In addition, the mounting portion A may be configured such that after the adhesive sheet S is transported to the target site, the adhesive sheet S is detached and installed at the target site. For example, when the distal end portion of the endoscope E moves to the vicinity of the affected area, the mounting portion A only needs to be able to be mounted in a state where the adhesive sheet S can be introduced into the body. The mounting part A can mount at least a part of the patch sheet S, and can be provided at any location of the body introduction aid 10 as long as the patch sheet S can be mounted in a state where the patch sheet S can be introduced into the body. . For example, the mounting portion A may be a part of the base B or a part of the sheet support piece 15.

In the present embodiment, the mounting portion A is composed of the pocket housing portion 12. The pocket housing part 12 has an opening 13 on the tip side. When the mounting portion A is constituted by the pocket accommodating portion 12, the adhesive sheet S can be accommodated in the pocket accommodating portion 12. In this case, since the adhesive sheet S is conveyed to the affected part while being accommodated in the pocket accommodating part 12, the shape of the adhesive sheet S is changed from the initial state before introduction into the body in the process of moving the adhesive sheet S to the vicinity of the affected part. Hard to collapse. In addition, when the adhesive sheet S has a property such that the adhesive force is activated by moisture, the adhesive sheet S is preferably attached to the affected part in a dry state. However, when the adhesive sheet S is accommodated in the pocket accommodating part 12, the pocket Most of the patch sheet S is accommodated in the accommodating portion 12 and introduced into the body. Therefore, it is possible to reduce the influence of the sticking sheet S on sticking due to moisture such as body fluids and blood, and it is possible to stick the sticking sheet S in a dry state. In this embodiment, the pocket accommodating portion 12 accommodates the adhesive sheet S and the sheet support piece 15. However, for example, when the place other than the pocket accommodating portion 12 is used as the attachment portion, the adhesive sheet S is used. You may accommodate only the sheet | seat support piece 15 without accommodating.

In this embodiment, the pocket accommodating part 12 is comprised by the two overlapping film sheets 11 and 11, and one film sheet serves as the base B as mentioned above. In the present embodiment, the outer peripheral edges of the two film sheets 11, 11 are sealed by heat welding, adhesion or the like so that the end on the distal end side when the distal end of the endoscope E is wound becomes the opening 13. It is stopped, and the pocket accommodating part 12 is comprised. The opening 13 is provided at the end of the film sheets 11, 11 on the front end side, and has an opening width that allows the adhesive sheet S to be taken in and out of the pocket housing part 12.

The pocket housing part 12 is not limited to the structure described above. For example, the pocket accommodating part 12 may be configured such that the base part B is constituted by a single sheet, and a separate pocket accommodating part 12 having an opening 13 is attached to the base part B. In addition, the pocket accommodating portion 12 is folded back by one film material, and the end portion on the distal end side when wound around the distal end portion of the endoscope E and each side other than the folded back side are sealed by heat welding, adhesion or the like. It may be configured. Moreover, the pocket accommodating part 12 may be comprised by using tube-shaped film material and sealing one side by heat welding, adhesion | attachment, etc. among two sides opened. In addition, when the pocket accommodating part 12 is a different body from the base B, the pocket accommodating part 12 may be comprised with the material same as the base B, and may be comprised with the material different from the base B. Good.

The opening 13 of the pocket accommodating portion 12 is provided only at the end on the front end side of the pocket accommodating portion 12, but all the sides other than the side on the rear end side of the pocket accommodating portion 12 may be the opening 13, and at least the inside view The shape of the opening 13 can be changed to various shapes as long as the adhesive sheet S can be taken in and out from the end on the front end side when wound around the front end side of the mirror E.

The shape of the pocket accommodating portion 12 and the shape of the adhesive sheet S accommodated in the pocket accommodating portion 12 are not limited to a rectangular shape, and any shape can be used as long as the adhesive sheet S having a desired shape can be accommodated in the pocket accommodating portion 12. The shape may be an ellipse, a circle, or a polygon. Moreover, the shape in which the pocket accommodating part 12 and the sticking sheet S differ may be sufficient.

The sheet support piece 15 is configured to be able to support the adhesive sheet S, and can support the adhesive sheet S so as to be able to be applied to the target site in the unfolded state. In this embodiment, the sheet support piece 15 has flexibility that can be wound around the distal end portion of the endoscope E, and supports the adhesive sheet S in a state of being wound around the distal end portion of the endoscope E. May have such a rigidity. The material of the sheet support piece 15 is not particularly limited as long as the material can transition while supporting the patch sheet S. For example, the sheet support piece 15 can use the same material as the material of the base B described above. The sheet support piece 15 may use a material different from the material of the base B.

As shown in FIG. 2, the sheet support piece 15 is configured to be able to transition between a mountable state and a deployed state. In the “wearable state”, for example, the body introduction assisting tool 10 including the sheet support piece 15 can be attached to a medical instrument such as the endoscope E introduced into the body, such as wrapping around the distal end portion of the endoscope E. This is a state in which the sheet support piece 15 is retracted from the affected part with respect to the deployed state. The “deployed state” is a state in which the sheet support piece 15 is moved or deformed from the mountable state and is displaced so that the patch sheet S mounted on the in-vivo assist device 10 approaches the affected part. In the present embodiment, as shown in FIG. 2, in the mountable state, the sheet support piece 15 is retracted in the front-rear direction, and the tip of the sheet support piece 15 protrudes from the opening 13 of the pocket housing portion 12. It is the state accommodated in the state. In the present embodiment, the unfolded state is a state in which the sheet support piece 15 has advanced from the two-dot chain line in FIG. However, the mountable state and the deployed state are not limited to the states shown in the present embodiment. For example, when the sheet support piece 15 can be expanded and contracted as in an embodiment described later, the mountable state is a state in which the sheet support piece 15 is contracted, and the unfolded state is a state in which the sheet support piece 15 is expanded. It is good also as a state which changed and changed in the direction containing the perpendicular direction ingredient to the surface of sheet support piece 15. The displacement of the sheet support piece 15 to the unfolded state is one or both of the displacement of the sheet support piece 15 toward the front end side and the displacement in the direction including the vertical component with respect to the surface of the sheet support piece 15. Any displacement that includes Further, the displacement to the deployed state may be a state in which the medical device such as the endoscope E is mounted so as to be able to be introduced into the body and separated from the medical device and deployed. May be in a state where the length in the width direction, which is a direction perpendicular to the insertion direction, is increased.

The transition from the mountable state of the seat support piece 15 to the unfolded state is performed by an operation member that causes the seat support piece 15 to transition in a predetermined direction. For example, in the present embodiment, the operation member is a grasping means (not shown) such as a forceps inserted into the forceps port of the endoscope E and coming out from the distal end side of the forceps port. The sheet support piece 15 and the leading end side of the adhesive sheet S are held by gripping means such as forceps, and the sheet support piece 15 is moved to the deployed state by moving the sheet support piece 15. The operation member that causes the sheet support piece 15 to transition is not limited to gripping means such as forceps. For example, the operation member may be a connection member 16 (see FIG. 3) that is connected to the sheet support piece 15 and can move the sheet support piece 15 in the front-rear direction, as shown in an embodiment described later. Good. In addition, as shown in an embodiment described later, the operation member includes a fluid supply unit (for example, a syringe) that supplies a fluid for expanding and contracting the sheet support piece 15 and a tubular member 16 that serves as a fluid flow path. (See FIG. 6).

In order to facilitate the transition from the mountable state of the sheet support piece 15 and the adhesive sheet S to the deployed state, for example, the outer periphery of the endoscope E and the in-vivo introduction tool wound around the outer periphery of the endoscope E. 10 is preferably configured so as to have a gap in the radial direction of the endoscope E. Due to this gap, the resistance when the sheet support piece 15 and the adhesive sheet S transition to the unfolded state is reduced, and the transition of the sheet support piece 15 and the adhesive sheet S is facilitated.

In order to form the above-described gap, for example, when the body introduction assisting tool 10 is attached to the endoscope E, the surface facing the outer periphery of the endoscope E of the body introduction assisting tool 10 and the outer periphery of the endoscope E A spacer interposed between the surfaces can be used. By attaching the in-vivo assist device 10 with the spacer interposed when the in-vivo assist device 10 is mounted on the endoscope E, a gap is generated by the thickness of the spacer after the spacer is removed. In addition, although the specific example of a spacer is mentioned later, if the structure of a spacer can produce a clearance gap, the shape and structure will not be specifically limited. Further, as will be described later, the distal end side of the body introduction assisting tool 10 is configured in an annular shape so that a gap is formed in advance between the distal end portion of the endoscope E and the sheet supporting piece 15 and the sticking piece 15. The transition to the developed state of the sheet S may be facilitated.

In the present embodiment, the sheet support piece 15 is at least one of the adhesive sheets S so that the adhesive sheet S supported by the sheet support pieces 15 does not hang down in the direction of gravity during the transition process from the mountable state to the deployed state. It is preferable that it is comprised so that a part may be supported. In this case, for example, the sheet support piece 15 may be configured to continuously support the adhesive sheet S from the mountable state to the expanded state, or from the middle of the transition process from the mountable state to the expanded state, You may comprise so that the sticking sheet S may be supported. In the case where the patch sheet S is supported in the middle of the transition process, for example, the sheet support piece 15 is accommodated in the pocket accommodating portion 12 and the upper surface of the pocket accommodating portion 12 or the like other than the pocket accommodating portion 12 in the mountable state. The case where the sticking sheet S is attached to the part is mentioned. In this case, the sheet support piece 15 and the adhesive sheet S are moved to the distal end side by gripping means such as forceps and the adhesive sheet S is supported by the sheet support piece 15 after being detached from the upper surface of the pocket housing portion 12. Moreover, the area of the adhesive sheet S supported by the sheet support piece 15 may increase as the state transitions from the mountable state to the deployed state. In addition, when the sticking sheet S is attached to the outside of the pocket housing portion 12, it is preferable that the sticking sheet S is in a wet state impregnated with physiological saline or the like because the shape at the time of attachment is easily maintained.

As described above, in the present embodiment, the sheet support piece 15 that supports the sticking sheet S is provided, and the sheet support piece 15 is configured to be able to transition between the mountable state and the unfolded state. Therefore, the adhesive sheet S can be easily pulled out from the in-vivo introduction aid 10 via the sheet support piece 15, and the adhesive sheet S can be attached to the affected area with a simple operation. Moreover, in this embodiment, the sheet | seat support piece 15 changes to a mounting | wearing possible state and an unfolded state, and the sticking sheet S is supported by the sheet | seat support piece 15 in an unfolded state at least before being stuck. Therefore, it is suppressed that the sticking sheet S hangs down in the direction of gravity in the unfolded state where the sticking operation of the sticking sheet S is performed, and the sticking operation becomes easy.

In this embodiment, the sheet support piece 15 is configured in a sheet shape as shown in FIG. 1 and has a support surface 15a for supporting the adhesive sheet S. The shape and structure of the sheet support piece 15 are not limited to those shown in the drawings as long as the sticking sheet S can be supported. In the present embodiment, the support surface 15a of the sheet support piece 15 is configured to support the entire patch sheet S, but the support surface 15a does not need to support the entire patch sheet S. For example, the support surface 15a of the sheet support piece 15 may be configured to support at least a part of the peripheral edge of the adhesive sheet S. For example, when the support surface 15a of the sheet support piece 15 is configured to support at least the rear end side of the adhesive sheet S in the peripheral portion of the adhesive sheet S, the rear end of the adhesive sheet S hangs down due to gravity. This can be suppressed. Further, when the support surface 15a of the sheet support piece 15 is configured to support at least the distal end side of the adhesive sheet S along the distal end side of the adhesive sheet S in the peripheral portion of the adhesive sheet S, the adhesive sheet It is easy to maintain the shape of the tip side of S. Further, when the support surface 15a of the sheet support piece 15 is configured to support at least both side edges connecting the front end and the rear end of the adhesive sheet S among the peripheral edges of the adhesive sheet S, the adhesive sheet S The shape of the side edge portion is maintained, and the sheet support piece 15 is suppressed from hanging down. Further, when the support surface 15a of the sheet support piece 15 is configured to support the corners of the adhesive sheet S, or when the periphery of the adhesive sheet S is supported in a frame shape, the shape of the adhesive sheet S is also the same. The sheet support piece 15 is suppressed from hanging down. Moreover, in this embodiment, although the support surface 15a of the sheet | seat support piece 15 is comprised larger than the area of the sticking sheet S, if the whole shape of the sticking sheet S does not collapse, the area of the sticking sheet S Alternatively, the support surface 15a of the sheet support piece 15 may be smaller, or the support surface 15a may have a notch or a hole.

Further, in the present embodiment, the sheet support piece 15 in the deployed state is configured to have a sheet shape so that a space can be secured between the affected part and the body. Since the sheet support piece 15 is in the form of a sheet, when the sheet support piece 15 is in a deployed state, a space is secured between the sheet support piece 15 and the inner wall of an organ in the affected area. In this case, the gastrointestinal tract and trachea are not blocked. For this reason, for example, it is possible to eliminate the adverse effects caused by the airway being closed or the duct being blocked. In addition, since the space is secured between the sheet support piece 15 and the body, the field of view of the objective lens Ec of the endoscope E is not blocked by the sheet support piece 15 even during the application work of the adhesive sheet S. The sticking operation of the sticking sheet S can be performed while ensuring the front view.

In the present embodiment, the sheet support piece 15 has a sheet shape, but when the sheet support piece 15 can be expanded and contracted as in the embodiment described later, the sheet support piece 15 has a non-cylindrical shape other than the sheet shape. May be. In this case as well, the gastrointestinal tract and trachea are not blocked. In addition, since the space is secured between the sheet support piece 15 and the body, the field of view of the objective lens Ec of the endoscope E is not blocked by the sheet support piece 15 even during the application work of the adhesive sheet S. The sticking operation of the sticking sheet S can be performed while ensuring the front view. Furthermore, when the sheet support piece 15 is in a non-cylindrical shape when expanded, the distal end portion of the endoscope E to which the in-vivo assist device 10 is attached is prevented from pressing the inner wall of the digestive tract due to the expansion of the sheet support piece 15. be able to. Further, the sheet support piece 15 may have a shape having a plurality of curved surfaces having different curvatures in a cross section perpendicular to the insertion direction.

Next, a specific example of the in-vivo aid 10 of the first embodiment will be described with reference to FIGS.

As shown in FIGS. 1 and 2, this in-vivo aid 10 includes a sheet support piece 15 that can be inserted into and removed from the opening 13 with respect to the pocket housing 12. The upper surface of the sheet support piece 15 is a support surface 15a for supporting the adhesive sheet S. The sheet support piece 15 is accommodated in the pocket accommodating portion 12 in a state where the adhesive sheet S is supported at least on the upper surface.

The planar shape of the sheet support piece 15 is formed in a convex shape in which the width on the rear end side is larger than the width on the front end side, and a notch surface 15f is provided on the front end side on both sides of the rear end portion. The pocket accommodating portion 12 is formed such that the width of the opening 13 is smaller than the width inside the pocket accommodating portion 12, and a terminal surface 12 b is provided on the rear end side of the sealing portion on the front end side. For this reason, when the sheet support piece 15 is pulled out from the opening 13 of the pocket accommodating portion 12, the notch surface 15 f of the sheet support piece 15 comes into contact with the end surface 12 b of the pocket accommodating portion 12.

In this embodiment, the length of the seat support piece 15 in the front-rear direction is set to be longer than the length of the pocket accommodating portion 12 in the depth direction (front-rear direction). That is, in the state where the sheet support piece 15 is accommodated in the pocket accommodating portion 12, the end portion 15b on the rear end side of the sheet support piece 15 abuts on the end portion 12a on the opposite side of the opening portion 13 of the pocket accommodating portion 12, An end 15c on the front end side of the sheet support piece 15 protrudes from the opening 13 and is substantially aligned with the front end of the adhesive sheet S. Note that the length of the sheet support piece 15 in the front-rear direction is not limited thereto, and when the sheet support piece 15 and the adhesive sheet S are accommodated in the pocket accommodating part 12 with their respective leading ends aligned, the adhesive sheet It is only necessary that the rear end side Sa of S be accommodated so that it is closer to the front (front end side) than the notch surface 15f of the sheet support piece 15. The length (width) on the front end side of the sheet support piece 15 may be smaller than the adhesive sheet S as long as it can be taken in and out from the opening 13.

In this embodiment, the material of the sheet support piece 15 is formed of a synthetic resin of the same material as the film sheets 11 and 11, but is not particularly limited as long as it can be taken in and out of the pocket housing portion 12. Alternatively, other materials may be used.
It is preferable that the sheet support piece 15 is made of a transparent material so that the adhesive sheet S superimposed on the upper surface can be confirmed with the endoscope E when the sheet support piece 15 is viewed from below.

Referring to FIG. 2, a method for introducing the patch sheet S into the body using the in-vivo aid 10 of the present embodiment will be described.

For example, after a gap 40 is formed between the outer peripheral surface of the endoscope E and the body introduction assisting tool 10 with a spacer or the like, a grasping means (not shown) such as forceps is inserted from the distal end surface Ea of the endoscope E. It advances and grasps both the sticking sheet S and the sheet | seat support piece 15 which protruded from the front end surface Ea (refer FIG. 25) of the endoscope E to the front end side.

When the distal end portion of the endoscope E is introduced to the affected part in the body, the grasping means is advanced and the adhesive sheet S and the sheet support piece 15 are pulled out as shown in FIG. The patch sheet S is pulled out while being supported by the support surface 15a of the sheet support piece 15. Even when the entire patch sheet S is pulled out from the pocket housing portion 12, the rear end portion of the sheet support piece 15 is the pocket housing portion. Since it is not pulled out from the inside, it does not hang down in the direction of gravity, and the support surface 15a of the sheet support piece 15 maintains the state of supporting the adhesive sheet S. In this state, the sticking sheet S is spread using the gripping means and the distal end portion of the endoscope E and attached to the affected part.

In this way, even if the entire patch sheet S is pulled out from the pocket accommodating portion 12, the support surface 15a of the sheet support piece 15 maintains the state in which the patch sheet S is supported, so that the patch sheet S does not hang down in the direction of gravity. It becomes easy to perform the pasting operation.

Further, when the sheet support piece 15 is pulled out from the opening 13 of the pocket housing portion 12, the notch surface 15f of the sheet support piece 15 comes into contact with the end surface 12b of the pocket housing portion 12 and resistance when pulled out increases. It is possible to prevent all the sheet support pieces 15 from being pulled out. It is also possible to prevent the sheet support piece 15 from dropping and being left in the body when the endoscope E is pulled out of the body after the patch sheet S is pasted to the affected area.

In the present embodiment, the adhesive sheet S is smaller than the sheet support piece 15 and is accommodated on the support surface 15a of the sheet support piece 15, but the size of the adhesive sheet S is not limited to this, You may accommodate in the pocket accommodating part 12 in the state folded and pinched | interposed the sheet | seat support piece 15 in between. In this case, the adhesive sheet S on the support surface 15a of the sheet support piece 15 is applied to the affected part, and then the adhesive sheet S located on the opposite surface of the support surface 15a of the sheet support piece 15 is spread with a gripping means or the like. What is necessary is just to affix on an affected part.

In the present embodiment, the sheet support piece 15 is configured to be able to transition between a mountable state and a deployed state that is deployed by introduction of a fluid. In the present embodiment, the sheet support piece 15 is configured to expand and contract as a fluid is introduced and discharged. Thereby, the seat support piece 15 can be attached to the distal end portion of the endoscope E, the fluid is not introduced, or the discharged state is contracted (attachable state), and the fluid is introduced in an expanded state. Transition to (expanded state) is possible. With the deformation of the sheet support piece 15 due to expansion, the patch sheet S supported by the sheet support surface 15 can move toward the affected area. Therefore, when the sticking sheet S is stuck, the sticking sheet S can be easily moved toward the affected part via the sheet support piece 15, and the sticking sheet S can be stuck to the affected part by a simple operation. .

In the present embodiment, the seat support piece 15 is mounted in the retracted state in the pocket housing portion 12 (base B), and is advanced forward in the contracted state with respect to the mountable state. It is comprised so that it may change between a state (refer FIG. 9) and the expansion | deployment state (refer FIG. 10) expanded from the advance state. In this embodiment, the sheet support piece 15 is at least one of the adhesive sheets S so that the adhesive sheet S supported by the sheet support pieces 15 does not hang down in the direction of gravity in the transition process from the mountable state to the advanced state. It is preferable that it is comprised so that a part may be supported. In this case, for example, the sheet support piece 15 may be configured to continuously support the adhesive sheet S from the attachable state to the advanced state, or from the middle of the transition process from the attachable state to the advanced state, You may comprise so that the sticking sheet S may be supported.

In this embodiment, the sheet support piece 15 is configured to expand while supporting the adhesive sheet S from the advanced state to the expanded state. In the present embodiment, the sheet support piece 15 is configured in a sheet shape having a support surface 15a on the upper surface in the contracted state. Further, in the expanded state, the sheet support piece 15 has a direction in which the support surface 15a is substantially perpendicular to the direction in which the body introduction assisting tool 10 is introduced into the body (or to the support surface 15a in the contracted state). It is configured to extend to. Thereby, in this embodiment, the patch sheet S can be moved toward the affected part while being supported by the support surface 15a of the sheet support piece 15, and can be moved to the affected part while maintaining the effective area of the patch sheet S. It becomes easy to apply. Further, in the present embodiment, the support surface 15a of the sheet support piece 15 expanded by the introduction of the fluid can be elastically deformed together with the adhesive sheet S according to the surface shape of the internal wall of the body where the affected part is located. is there. Therefore, the patch sheet S can be easily pasted even in an affected area having a complicated surface shape.

The structure of the sheet support piece 15 is not particularly limited as long as the sheet support piece 15 can be switched between the mountable state and the deployed state by introducing a fluid. In the present embodiment, as shown in FIG. 7, the sheet support piece 15 includes an airtight chamber 152 that is formed fluid-tight, and is configured to be in an expanded state by introduction of fluid into the airtight chamber 152. Has been. In the present embodiment, the sheet support piece 15 is connected to a tubular member 16 having a lumen, the tip of which is inserted into the pocket accommodating portion 12 from the end opposite to the opening 13. The lumen of the tubular member 16 communicates with the hermetic chamber 152 and is configured to introduce fluid into the hermetic chamber 152 through the lumen. One opening of the tubular member 16 communicates with the airtight chamber 152, and the other opening is connected to a fluid supply unit (not shown) that supplies fluid such as air into the airtight chamber 152 such as a syringe. In the present embodiment, the tubular member 16 is slidably inserted through the outer cylinder 17. In this case, the sheet support piece 15 can be moved from the mountable state to the advanced state by moving the tubular member 16 to the front end side in the outer cylinder 17.

In the present embodiment, as shown in FIG. 11, the sheet support piece 15 in the deployed state is configured to have a non-cylindrical shape so that a space SP can be secured between the affected part and the body. ing. In this case, as shown in FIG. 11, when the sheet support piece 15 is in the deployed state, a space SP is secured between the sheet support piece 15 and the inner wall of the organ in the affected area. Therefore, the gastrointestinal tract and trachea are not blocked. Therefore, for example, conventionally, it has been necessary to perform a careful work so that the airway is not closed or the pipeline is not blocked. It can be done easily.

The shape of the sheet support piece 15 in the unfolded state is a non-cylindrical shape, and the cross-sectional shape in the width direction, which is a direction perpendicular to the direction of introduction into the body, is non-circular, and between the affected part and the body. In order to secure the space SP, in the cross-sectional shape in the width direction, the length in the width direction may be configured to be longer than the length in the vertical direction, which is a direction perpendicular to the introduction direction and the width direction. There is no particular limitation. The cylindrical shape is a shape formed such that a circular cross section having a circular cross section in the width direction has a length, and includes shapes such as a cylindrical shape and a rugby ball shape. For example, a balloon made of a stretchable material is uniformly expanded in a direction perpendicular to the introduction direction, and thus has a cylindrical shape when inflated with a fluid. For example, as shown in FIG. 11, the sheet support piece 15 in the deployed state preferably expands so as not to block the front of the objective lens Ec and / or the forceps port Eb of the endoscope E. In this case, the field of view of the objective lens Ec of the endoscope E and the space SP in front of the forceps port Eb are not blocked by the expanded sheet support piece 15 at the time of applying the application sheet S. Therefore, the functions of instruments such as forceps protruding from the objective lens Ec of the endoscope E and the forceps port Eb toward the distal end are not easily restricted. As the non-cylindrical shape of the sheet support piece 15 in the unfolded state, for example, as shown in FIGS. 10 and 11, a flat shape expanded in a direction perpendicular to the introduction direction in the body can be used. When the sheet support piece 15 in the unfolded state is flat, a wide space SP is secured on the distal end side of the endoscope E. In the present embodiment, the sheet support piece 15 in the unfolded state is configured to expand in the same manner on both the upper surface side and the lower surface side with respect to the sheet-like sheet support piece 15 before the unfolded state. However, the sheet support piece 15 has an expansion amount on the upper surface side that is the affected area side larger than an expansion amount on the lower surface side, for example, by making the rigidity of the material on the lower surface side higher than the rigidity of the material on the upper surface side. Alternatively, the lower surface side may be configured not to expand.

The number of the airtight chambers 152 provided in the sheet support piece 15 is not particularly limited, and the number of the airtight chambers 152 may be one or plural. In the present embodiment, as shown in FIGS. 7 and 10, the sheet support piece 15 is divided into two airtight chambers 152 a and 152 a communicating with each other, but the number of the airtight chambers 152 is not particularly limited. Further, when there are a plurality of the airtight chambers 152, the partitioning direction may be partitioned in the front-rear direction, or may be partitioned in the width direction in the direction orthogonal to the front-rear direction in the sheet support piece 15.

Next, a specific example of the in-vivo aid 10 of the fifth embodiment will be described with reference to FIGS.

As shown in FIG. 7, the sheet support piece 15 in this embodiment has a substantially rectangular planar shape, and the outer peripheral edges of the two overlapping support film sheets 151 and 151 are sealed by heat welding or the like. An airtight chamber 152 is formed.
In the central portion of the airtight chamber 152, a sealing portion 15d is formed up to a middle position by thermal welding or the like from the end portion 15c on the front end side to the end portion 15b on the rear end side. The chambers 152a and 152a are formed by being divided into two in the direction in which they are made.

The front end of a tubular connection member (tubular member) 16 is connected to the sheet support piece 15 at an end portion 15 b on the rear end side of the sheet support piece 15 so that only the inner cavity communicates with the airtight chamber 152. .
Although the material of the tubular member 16 is not limited, it is comprised from the tube which has the softness | flexibility which consists of synthetic resins, such as polyethylene, a polypropylene, a polystyrene, a polyvinyl chloride, for example. When the material of the tubular member 16 is a synthetic resin of the same material as the support film sheets 151 and 151, the tubular member 16 is fixed to the tubular member 16 by thermal welding at a time when sealing the periphery of the support film sheets 151 and 151. Can do.

The rear end portion (not shown) of the tubular member 16 is connected to a syringe via a luer lock-shaped connector part or the like. When the plunger of the syringe is pushed, the air in the syringe is introduced into the airtight chamber 152 of the sheet support piece 15 through the lumen of the tubular member 16, and the sheet support piece 15 expands. Further, when the plunger of the syringe is pulled, the air in the airtight chamber 152 of the sheet support piece 15 is sucked into the syringe through the lumen of the sheet support piece 15, so that the sheet support piece 15 contracts.

A gripping portion 15 e for gripping the sheet support piece 15 by a gripping means such as forceps protrudes from the end portion 15 c on the front end side of the sheet support piece 15. As shown in FIG. 6, when the sheet support piece 15 is accommodated in the pocket accommodating portion 12, the gripping portion 15 e protrudes from the opening portion 13. In the present embodiment, the grip portion 15e is formed at the center of the end portion 15c on the front end side of the sheet support piece 15, but may be formed over the entire end portion 15c on the front end side of the sheet support piece 15. Good. The shape of the gripping part 15e may be a pocket shape (bag shape) or a hole as long as it can be gripped by the gripping means, or may be a ring member formed of a thread or the like. Moreover, you may comprise so that the sticking sheet S may be pulled out from the front-end | tip of the endoscope E using a press part instead of a holding part.

A method for attaching the in-vivo introduction aid 10 of this embodiment to the endoscope E and an in-body introduction method for the adhesive sheet S using the in-body introduction aid 10 will be described.
In this embodiment, for example, after the body introduction assisting tool 10 is wound around the distal end portion of the endoscope E with a spacer 20 (see FIG. 23) described later interposed therebetween, the spacer 20 is extracted. At this time, as shown in FIG. 8, in the body introduction aid 10, the grip portion 15 e and the sealing portion 15 d located at the center of the sheet support piece 15 are closest to the forceps port Eb on the distal end surface Ea of the endoscope E. It is wound around the outer peripheral surface of the endoscope E so as to be located at a location.

Thereafter, a grasping means (not shown) such as forceps is advanced from the forceps port Eb on the distal end surface Ea of the endoscope E, and the sticking sheet S protruding from the distal end surface Ea of the endoscope E toward the distal end side. The grip part 15e of the sheet support piece 15 is gripped. And if the front-end | tip part of the endoscope E is introduce | transduced to the affected part in a body, a holding means will be advanced and the whole sticking sheet S will be pulled out. The pulled-out sticking sheet S and the sheet support piece 15 are pulled out while maintaining the shape wound around the endoscope E as shown in FIG.

Next, when a fluid such as air is introduced into the airtight chamber 152 of the sheet support piece 15 through the tubular member 16, the sheet support piece 15 expands as shown in FIGS. 10 (A) and 10 (B). The distal end surface Ea of the endoscope E is flatter or slightly curved at the distal end side, and the adhesive sheet S supported by the support surface 15a of the sheet support piece 15 is pasted so as to be pressed against the affected area.

At this time, the airtight chamber 152 of the sheet support piece 15 is divided into chambers 152a and 152a by the sealing portion 15d, and the sealing portion 15d is positioned at a position closest to the forceps port Eb on the distal end surface Ea of the endoscope E. Thus, since the body introduction assisting tool 10 is wound around the outer peripheral surface of the endoscope E, the sheet support piece 15 has a wing shape (flat shape) sandwiching the gripping means advanced from the forceps port Eb of the endoscope E. In one example) it expands on both sides.
When the sealing portion 15d does not exist, the sheet support piece 15 expands in the vertical direction in the drawing of FIG. For this reason, there is a possibility that the gripping by the gripping means advanced from the forceps port Eb of the endoscope E may be released or the endoscope E or the gripping means may be damaged. Further, when the sheet support piece 15 is expanded, the fixing portion 14 accommodated in the pocket accommodating portion 12 on the lower side of the drawing of FIG. 10B is pulled out by expansion, and the sheet support piece 15 is pulled into the pocket. There is also a possibility that it cannot be accommodated again in the accommodating part 12. In the present embodiment, since the sheet support piece 15 expands on both sides with the forceps port Eb of the endoscope E interposed therebetween, the above-described fear can be avoided.

In the expanded state of the sheet support piece 15, as shown in FIG. 11, the support surface 15 a that is the upper surface of the sheet support piece 15 is pressed against the affected area, while a large space is provided on the lower surface side of the sheet support piece 15. SP is secured. Therefore, in the present embodiment, unlike a balloon-like structure that swells into a cylindrical shape, the duct in the body is not blocked, and a space SP is secured in front of the objective lens Ec and the forceps port Eb of the endoscope E. . Therefore, it is possible to eliminate the adverse effects caused by blockage of the duct such as the digestive tract and the trachea, and the function of the instrument such as the forceps protruding from the objective lens Ec of the endoscope E or the forceps port Eb toward the distal end is restricted. Hateful.

After the sticking sheet S is attached to the affected area, the gripping means is released and the gripping means is retracted, and then the fluid of the sheet support piece 15 is extracted to contract the sheet support piece 15. And the sheet | seat support piece 15 is accommodated in the pocket accommodating part 12 again by pulling the tubular member 16 to the rear-end side. Thereby, since the observation visual field of the front end side of the endoscope E can be secured, the pasting state of the patch sheet S on the affected part is confirmed by the endoscope E. After the other treatment by the endoscope E is completed, the endoscope E is pulled out from the body.

The sheet support piece 15 in this modification differs from the sheet support piece 15 of the embodiment of FIG. 7 in that the grip portion 15e is not present, but a grip portion 15e may be provided.
As shown in FIG. 13, the sheet support piece 15 is folded in half so that the adhesive sheet S is on the outside in a state where the adhesive sheet S is superimposed on the support surface 15 a. At this time, the end portion 15c on the front end side that is folded back is located on the front end side with respect to the end portion 15b on the rear end side to which the tubular member 16 is connected. In this state, as shown in FIG. The piece 15 is accommodated in the pocket accommodating portion 12 of the body introduction aid 10.

The method for introducing the patch sheet S into the body using the in-body introduction aid 10 of the present embodiment will be described with respect to differences from the fifth embodiment.

The in-vivo assisting tool 10 in this state is wrapped around the distal end portion of the endoscope E via a spacer 20 (see FIG. 23) or the like only, and the spacer 20 is pulled out to remove the outer peripheral surface of the endoscope E and the in-vivo introduction assisting tool. After the gap 40 (see FIG. 25) is formed between the distal end of the endoscope E and the affected part of the body, the distal end of the endoscope E is introduced to the affected part without grasping the adhesive sheet S and the sheet support piece 15 by the grasping means.

Next, the tubular member 16 is pushed to the front end side to push out the folded sheet support piece 15 until the entire adhesive sheet S and the end portion 15c on the front end side of the sheet support piece 15 come out of the opening 13.
When a fluid such as air is introduced into the hermetic chamber 152 of the sheet support piece 15 through the tubular member 16, the sheet support piece 15 expands, the half-folded state is released, extends to the front end side, and is flat or slightly curved Thus, the patch sheet S supported by the support surface 15a of the sheet support piece 15 is pasted so as to be pressed against the affected area.
After sticking the patch sheet S to the affected part, the fluid of the sheet support piece 15 is extracted and contracted, and the tubular member 16 is pulled to the rear end side, whereby the sheet support piece 15 is stored again in the pocket storage part 12.

In the in-vivo introduction assisting tool 10 of the present embodiment, as shown in FIG. 14, the mounting portion A has an engaging portion 18 that can engage at least both ends in the width direction of the adhesive sheet S. In the present embodiment, the mounting portion A having the engaging portion 18 is the pocket accommodating portion 12. The patch sheet S is attached to the distal end side of the pocket accommodating portion 12 or the upper surface of the pocket accommodating portion 12 by engaging with the engaging portion 18 and is provided outside the in vivo introduction assisting tool 10 when introduced into the body. .

As shown in FIG. 15, the engaging portion 18 is configured such that both end portions in the width direction of the adhesive sheet S are engaged at least. The width direction of the adhesive sheet S is a direction orthogonal to the front-rear direction in a state where the adhesive sheet S is flat. Both end portions in the width direction of the adhesive sheet S need only be predetermined regions on both end sides in the width direction, and need not be edges in the width direction of the adhesive sheet S. In this embodiment, the engaging portion 18 is formed over the entire width direction, as shown in FIGS. 14 and 15. In this case, the range of engagement with the adhesive sheet S is increased, and the adhesive sheet S can be more reliably engaged. The engagement portion 18 can be introduced into the body in a state where the flat region of the patch sheet S corresponding to the affected part is maintained in a state where the sheet support piece is attached to the medical instrument such as the endoscope E. Further, it may be provided so as to engage with the sticking sheet S. Moreover, the engaging part 18 may be comprised so that the sticking sheet S may be engaged with the sticking sheet S so that the flat part of a predetermined area may be formed in the unfolded state.

As described above, the mounting portion A has the engaging portions 18 at which both end portions in the width direction of the adhesive sheet S can be engaged at least. In this case, for example, during the introduction of the body introduction aid 10 into the body, such as during the movement from the insertion of the endoscope E into the body to the affected area, as shown in FIG. The adhesive sheet S exposed to the outside moves in the body with both end portions engaged with the engaging portion 18. Therefore, when the patch sheet S moves in the body together with the body introduction assisting tool 10, both end portions of the patch sheet S may be turned up because both end portions of the patch sheet S are engaged with the engaging portions 18.

On the other hand, when the body introduction assisting tool 10 is introduced into the body, the sticking sheet S is restricted from moving with respect to the mounting portion A on the side opposite to the introduction direction into the body. Therefore, even if the end of the adhesive sheet S that is not grasped by the grasping means such as forceps is to be turned when introduced into the body, the engaging portion 18 is caught and the end of the adhesive sheet S is prevented from being turned. Therefore, the entire adhesive sheet S is conveyed in a state close to the original state without the end of the adhesive sheet S being turned up. Moreover, in this embodiment, since the mounting part A has the engaging part 18, the engaging sheet 18 can be simply engaged with the engaging part 18 from the outside of the body introduction assisting tool 10. Installation is complete. Therefore, it is possible to omit the troublesome work of storing the adhesive sheet S a plurality of times in the pocket accommodating portion 12 which is a narrow space, such as when attaching a plurality of adhesive sheets S to the affected area, and to reduce the application time of the adhesive sheet. It can be shortened. The engaging part 18 may be engaged with the adhesive sheet S in the introduction direction, and the adhesive sheet S can be detached by moving the engaging part 18 in either direction.

The shape of the engaging portion 18 is not particularly limited as long as it can be engaged with both end portions of the adhesive sheet S to suppress turning up of both end portions of the adhesive sheet S. For example, as shown in FIG. 14, the engaging portion 18 may be provided with a plurality of protruding engaging portions protruding toward the distal end side at the end edge of the pocket accommodating portion 12. Moreover, the engaging part 18 may be provided in the upper surface of the pocket accommodating part 12, as FIG. 16 shows.

Moreover, the shape in which the pocket accommodating part 12 and the sticking sheet S differ may be sufficient.

According to this embodiment, since the adhesive sheet S of the in-vivo assist device 10 is only sandwiched between two overlapping film sheets 11, 11, the adhesive sheet S can be easily taken out and applied to the affected area. Can do.
Further, since the adhesive sheet S sandwiched between the film sheets 11 and 11 is wound around the endoscope E with a gap 40 formed between the film 20 and the endoscope E by the thickness of the spacer 20, the adhesive sheet S is attached. The sheet S can be reliably taken out between the film sheets 11 and 11.
Since the gap 40 between the endoscope 20 provided by the spacer 20 differs depending on the thickness of the film sheets 11 and 11 and the adhesive sheet S and the length wound around the endoscope E, the necessary gap 40 can be obtained. What is necessary is just to set the thickness of the spacer 20 suitably.

FIG. 21 shows a spacer 20 that is used when the in-vivo assisting tool 10 containing the patch sheet S is wound around the distal end portion of the endoscope E. The spacer 20 described below can also be used when the in-vivo aid 10 described in the first to eighth embodiments is wound around the distal end portion of the endoscope E.

The spacer 20 has a cylindrical portion having one end side as a knob portion 21 and the other end side as a main body portion 22. The knob portion 21 is formed by cutting out the lower portion of the cylindrical body along the axial direction, and has an arc shape in a cross-sectional view. The main body portion 22 is a portion attached to the distal end portion of the endoscope E, and the distal end side end portion 22 b is formed by forming the knob portion 21. A diameter adjusting portion 22a is formed in the main body portion 22 by cutting an angular position opposite to the knob portion 21 with respect to the center of the cylindrical body over the entire axial direction.

The inner diameter of the cylindrical body of the spacer 20 is slightly smaller than the outer diameter of the distal end portion of the endoscope E to which the spacer 20 is attached, and is provided in the main body portion 22 when being attached to the distal end portion of the endoscope E. When the gap between the diameter adjusting portions 22a is opened, a difference in diameter from the endoscope E can be absorbed, and the spacer 20 can be mounted along the outer periphery of the endoscope E.

The spacer 20 is made of a pipe made of metal such as stainless steel or a pipe made of synthetic resin such as polyethylene, polypropylene, polystyrene, polyvinyl chloride or the like, but a synthetic resin pipe having flexibility is preferable. The spacer 20 may be made of other materials or shapes, but is preferably a cylindrical body because the state after attachment is stable.

Next, a method for mounting the in-vivo introduction aid 10 on the endoscope E and a in-body introduction method for the patch sheet S using the in-body introduction aid 10 will be described. In the following, a method of mounting on the endoscope E using the in-vivo introduction aid 10 of the ninth embodiment and an in-body introduction method of the adhesive sheet S using the in-body introduction aid 10 will be described. The method of attaching to the endoscope E and the method of introducing the adhesive sheet S into the body can also be applied to the first to eighth embodiments.

First, as shown in FIG. 22, the end portion 22 b on the distal end side of the main body portion 22 of the spacer 20 and the distal end surface Ea of the distal end portion of the endoscope E are aligned, and the spacer 20 is placed at the distal end portion of the endoscope E. Install (first step). The knob portion 21 protrudes toward the distal end side of the endoscope E.
Next, the other part of the adhesive sheet S is accommodated in the pocket accommodating part 12 of the body introduction aid 10 such that a part of the adhesive sheet S protrudes from the opening 13 of the pocket accommodating part 12. Then, as shown in FIG. 23, the opening 13 is aligned with the distal end surface Ea of the distal end portion of the endoscope E, and the spacer 20 is interposed only on the distal end side of the body introduction assisting device 10 (pocket accommodating portion 12). Wrap it around the tip of the endoscope E in a state. On the distal end surface Ea of the endoscope E, for example, a forceps port Eb through which a gripping means (not shown) such as forceps can be inserted is provided so as to be able to advance and retreat. As shown in FIG. 10 is wound so that the central portion of the end portion on the front end side of the adhesive sheet S is positioned in the vicinity of the forceps port Eb. If the end portion on the front end side of the adhesive sheet S is disposed at a position where it can be gripped by forceps, the end portion of the end portion on the front end side of the adhesive sheet S is positioned in the vicinity of the forceps port Eb. The part may be located. The protruding portion of the sticking sheet S protruding from the film sheets 11 and 11 is in an exposed state and faces the forceps port Eb side. Therefore, the part in which the adhesive sheet S is accommodated from the pocket accommodating part 12 is pulled out by forceps so that the adhesive sheet S can be easily separated from the endoscope E.

Next, as shown in FIG. 24, the fixing portion 14 of the in-vivo assist device 10 is fixed to the outer peripheral surface of the endoscope E by the fixing tape 30 (second step). At this time, if the rear end side of the adhesive sheet S in the pocket accommodating portion 12 is simultaneously fixed with the fixing tape 30, the adhesive sheet S cannot be pulled out from the pocket accommodating portion 12. For this reason, as shown in FIG. 20, it is preferable to increase the width of the fixing portion 14 of the in-vivo introduction aid 10 so that the fixing tape 30 does not cover the pocket housing portion 12.
Furthermore, the tip tape 31 is wound around the position corresponding to the main body 22 of the spacer 20 from the outside of the body introduction assisting tool 10. The length of the main body portion 22 of the spacer 20 in the axial direction is slightly longer than the width of the tip tape 31.
The width of the fixing tape 30 and the distal end tape 31 is such that the distal end portion of the endoscope is easily bent.
It is preferable to make the body introduction assisting tool 10 as small as possible within a range where it can be firmly fixed to the endoscope E. The fixed tape 30 and the tip tape 31 may be composed of a stretchable tape. Further, the fixing tape 30 and the leading end tape 31 may be made of the same material tape, or may be made of different materials.

Next, when the knob portion 21 of the spacer 20 is picked and the spacer 20 is extracted from the distal end portion of the endoscope E, as shown in FIG. 25, the outer peripheral surface of the endoscope E and the body introduction assisting tool 10 (pocket housing portion). 12) is formed (third step). As described above, in order to remove the spacer 20 after the distal end tape 31 is wound around the distal end portion of the body introduction assisting device 10, the width of the body assisting device 10 in the direction of winding around the endoscope E (the opening 13 in FIG. 20). The opening width + the width of the surrounding sealing portion is preferably longer than the outer peripheral length of the distal end portion of the endoscope E. When it is desired to make the opening width of the opening portion 13 smaller than the outer peripheral length of the distal end portion of the endoscope E, the width of the surrounding sealing portion may be increased.

In the state shown in FIG. 25, the endoscope is arranged so that the gripping means (not shown) is advanced from the forceps port Eb on the distal end surface Ea of the endoscope E so that the adhesive sheet S can be taken out from the pocket housing portion 12 by the gripping means. The sticking sheet S protruding from the front end surface Ea of the mirror E to the front end side is gripped. An objective lens (observation imaging member) Ec is attached to the distal end surface Ea of the endoscope E, and the portion of the endoscope E is projected from the distal end surface Ea of the endoscope E of the adhesive sheet S to the distal end side. Since the observation visual field may be blocked, the endoscope E is inserted into the body in a state in which the gripping means is slightly retracted and the protruding portion of the adhesive sheet S is pulled back to secure the observation visual field of the endoscope E. Insert into.

When the distal end portion of the endoscope E is introduced to the affected area in the body, the gripping means is advanced to bring the majority of the adhesive sheet S into a state of being pulled out as shown in FIG. During this time, the adhesive sheet S is spread and applied while being pressed against the affected area, and then the remaining adhesive sheet S is attached while being pulled out while the endoscope E is retracted. The endoscope E may be retracted while being pressed by the distal end portion of the endoscope E from the beginning of the sticking sheet S being pulled out.
The width in the winding direction of the adhesive sheet S to be wound around the distal end portion of the endoscope E can be pulled out even if it is longer than the outer peripheral length of the distal end portion of the endoscope E. It is preferable to be shorter than the outer peripheral length of the tip of the mirror E.

According to this embodiment, since the adhesive sheet S of the in-vivo assist device 10 is only sandwiched between two overlapping film sheets 11, 11, the adhesive sheet S can be easily taken out and applied to the affected area. Can do.
Further, since the adhesive sheet S sandwiched between the film sheets 11 and 11 is wound around the endoscope E with a gap 40 formed between the film 20 and the endoscope E by the thickness of the spacer 20, the adhesive sheet S is attached. The sheet S can be reliably taken out between the film sheets 11 and 11.
Since the gap 40 between the endoscope 20 provided by the spacer 20 differs depending on the thickness of the film sheets 11 and 11 and the adhesive sheet S and the length wound around the endoscope E, the necessary gap 40 can be obtained. What is necessary is just to set the thickness of the spacer 20 suitably.

Note that the adhesive sheet S may be wound around the distal end portion of the endoscope E without using the spacer 20. In this case, the body introduction assisting tool 10 is wound around the distal end portion of the endoscope E, and is fixed with an appropriate strength when the distal end tape 31 is wound from above the body introduction assisting tool 10 to the distal end side. And the front-end | tip part of the endoscope E is introduce | transduced into a body, The sticking sheet S is taken out from between the film sheets 11 and 11 of the in-vivo auxiliary | assistance introduction tool 10 with a holding means, and is affixed on an affected part.

In addition, the body introduction aid 10 is configured in an annular shape so that a gap is formed between at least the distal end side of the mounting portion A and the outer periphery of the distal end portion of the endoscope E without using the spacer 20. May be. In this case, since the tip end side of the mounting portion A is annular so that a gap is formed between the outer periphery of the tip end portion of the endoscope E, it is not necessary to fix the tip end side with the tip tape 31 or the like. The attachment of the in-vivo aid 10 to the endoscope E is completed simply by stopping the rear end side with a tape or a rubber band. Therefore, an operation of attaching a spacer to the distal end side of the body introduction aid 10 or winding a tape becomes unnecessary. Therefore, the work of attaching the in-vivo assist tool 10 to the endoscope E is simplified, and the time required for the work of applying the adhesive sheet S to the affected area is shortened.

In addition, the body introduction aid 10 in which the distal end side of the mounting portion A is configured in an annular shape may be configured such that, for example, the pocket accommodating portion 12 is cylindrical in the front-rear direction, or the distal end of the pocket accommodating portion 12 You may be comprised so that only the side may become a cylinder shape.
