The conventional surgical training apparatus such as the above publication is highly functional, but the price is high, the weight is large, and the occupied space is large. For this reason, this type of surgical training apparatus is usually installed immovably in a specific place such as a training room or a laboratory. Therefore, it can be used only in the specific place, and is not suitable for use such as bringing it to an external seminar venue for demonstration. Also, the number of units that can be installed is limited, and it was difficult for a large number of trainees to practice at once.
In view of the above circumstances, an object of the present invention is to provide a treatment training apparatus having a simple structure that is inexpensive and lightweight and can be carried.

The present invention is a surgical training apparatus for training the operation of a surgical instrument inserted into a human body,
A pseudo body surface including a pseudo body surface having a pseudo incision portion and a support portion, wherein the pseudo body surface covered with the pseudo body surface is formed by supporting the pseudo body surface by the support portion. It is possible to transform between a state and a second state that can be made more compact than the first state by releasing the support.

  When this surgical training apparatus is used, the simulated surgical cavity, that is, a space imitating a human body cavity is formed by setting the surgical training apparatus to the first state. Then, a surgical instrument such as an endoscope or forceps is inserted into the pseudo body cavity from the pseudo incision portion to perform surgical training. When the surgical training apparatus is not used, the surgical training apparatus can be made compact by placing the surgical training apparatus in the second state. Here, the release of the support means that the support part is not in a state of supporting the pseudo body surface so as to be in the first state, and the support part is separated from the pseudo body surface or folded. , Including being knocked down, disassembled, or shrunk. “Compactable” means that the occupation space of the surgical training apparatus can be made smaller than that in the first state, and includes, for example, that the entire surgical training apparatus or its components can be folded, disassembled, and compressed. As a result, the pseudo body cavity is crushed or disappears. Therefore, the treatment training apparatus can be easily stored and stored, and can be easily carried.

It is preferable that at least the pseudo body surface of the pseudo body surface and the support portion is transparent.
Thereby, the pseudo body cavity can be directly visually recognized through the pseudo body surface. Therefore, the posture and movement of a surgical instrument such as an endoscope in the pseudo body cavity can be confirmed without installing a camera in the pseudo body cavity. Of course, a TV monitor is also unnecessary. Therefore, the treatment training apparatus can be greatly reduced in price.

According to the first aspect of the treatment training apparatus, the pseudo body surface is a hard plate shape, and the support portion can be rotated between an expanded position and a folded position at both ends of the pseudo body surface. The leg portion at the unfolded position is substantially orthogonal to the pseudo body surface, and the leg portion at the folding position is along the pseudo body surface.
By setting the pair of legs to the deployed position, the treatment training device can be in the first state. By placing these pair of legs on the pseudo-surgical table, the pseudo-body surface can be supported away from the pseudo-surgical table, and a pseudo-body cavity is formed between the pseudo-body surface and the pseudo-surgical table below the pseudo body surface. Can be defined. As a result, surgical training can be performed. Moreover, by making a pair of leg part into the said folding position, a treatment training apparatus can be made into a 2nd state, and it can be made compact. By simply rotating the legs, the treatment training device can be easily transformed from the first state to the second state, or from the second state to the first state.

It is preferable that an angle formed between the leg portion at the deployed position and the pseudo body surface is greater than 90 ° to 120 °.
By exceeding 90 °, the pair of leg portions are inclined so as to be separated from each other toward the lower side (the side opposite to the side connected to the pseudo body surface). Therefore, the surgical training apparatus in the first state can be structurally stabilized, and the surgical training can be performed stably. Further, by setting the angle to be 120 ° or less, the support height of the pseudo body surface can be ensured, and as a result, the volume of the pseudo body cavity can be secured.

It is preferable that an anti-slip material is provided on an end surface of the leg portion opposite to the connection side with the pseudo body surface.
Thus, the treatment training apparatus can be prevented from slipping during the treatment training, and the treatment training can be performed more stably.

According to the second aspect of the surgical training apparatus, the main surface portion of the outer package that has a flexible outer packet and a deformable shape-retaining frame that constitutes the support unit and that should face upward in the outer package has the pseudo incision. And construct the pseudo body table,
In the first state, the shape retaining frame is formed into a frame shape, and the outer package is three-dimensionalized into a box shape by wrapping the shape retaining frame so that it can be taken out.
In the second state, the shape retaining frame can be made compact by releasing the frame shape.
When using this surgical training apparatus, it is set to the first state. As a result, the outer package can be three-dimensionalized into a box shape, and a space serving as a pseudo body cavity can be secured inside. Then, a surgical instrument such as an endoscope or forceps is inserted into the pseudo body cavity from the pseudo incision portion to perform surgical training. When the treatment training device is not used, the shape retaining frame is taken out from the outer packaging, and the outer packaging and the shape retaining frame are separated, so that the outer packaging can be deflated to form a plane, and further folded to be compact. . Further, the shape retaining frame can be made compact by releasing the frame shape. Here, releasing the frame shape means that the shape retaining frame is not the frame shape in the first state by disassembling or folding the shape retaining frame. “Compactable” means that the occupied space can be made smaller than the first state of the frame shape, for example, that the shape-retaining frame can be disassembled into a plurality of constituent members or folded. As a result, the entire treatment training apparatus can be made compact and not only easy to store, but also easily carried.

  The outer package is preferably made of a transparent material. Thus, the internal pseudo-body cavity can be directly visually recognized through the main surface portion of the outer packet. Therefore, the posture and movement of a surgical instrument such as an endoscope in the pseudo body cavity can be confirmed without installing a camera in the pseudo body cavity. Of course, a TV monitor is also unnecessary. Therefore, the treatment training apparatus can be reliably reduced in price.

It is preferable to provide tension applying means for applying tension to the main surface portion by pulling the outer packet.
Accordingly, the surgical instrument can be easily inserted into the pseudo body cavity from the pseudo incision portion, and the operability of the surgical instrument can be prevented from being hindered.
As said tension | tensile_strength provision means, an adhesive tape is mentioned, for example. While pulling the side part of the outer package downward with the adhesive tape, the adhesive tape is pasted so as to straddle the pseudo-treatment table from the side part. Thereby, tension can be given to the main surface portion of the outer packet, and at the same time, the treatment training device can be fixed to the pseudo-treatment table.

The shape-retaining frame includes a plurality of frame members, and in the first state, the plurality of frame members are joined in a separable manner to form a frame shape as a whole, and in the second state, the plurality of frame members It is preferable that the frame members are disassembled.
Thereby, when using the treatment training apparatus, the outer packaging can be three-dimensionalized by assembling the shape-retaining frame and storing it in the outer packaging. Further, when the surgical training apparatus is not used, the shape retaining frame can be reliably made compact by disassembling the shape retaining frame into a plurality of frame members, and can be easily carried with certainty.

At least some of the plurality of frame members are formed with slits that can be held by inserting other intersecting frame members, and in the first state, the plurality of frame members are assembled in a grid pattern. It is preferable.
Thus, the shape retaining frame can be easily assembled and disassembled. Furthermore, it can be reliably made compact by stacking a plurality of disassembled frame members, and can be easily carried with certainty.

  According to the treatment training apparatus of the present invention, the structure is simple, inexpensive and lightweight, and can be easily carried.

As shown in FIG. 2, the surgical training apparatus 1 in the second state is in the first state when the support of the pseudo body surface 12 is released by the support unit 20 and the pseudo body cavity 19 is eliminated (collapsed or disappeared). It becomes possible to make more compact. In the following description, it is assumed that the treatment training device 1 is in the first state (an assembled state at the time of use) unless otherwise specified. The total weight of the treatment training apparatus 1 is preferably about 100 to 1000 g.

The treatment training device 1 will be further described in detail.
The outer packet 10 is configured by forming the film 11 (pack body) into a bag shape. The film 11 is made of a flexible and transparent resin (transparent material). Examples of such a resin include, but are not limited to, polyethylene (PE). The film 11 may have a laminate structure in which a plurality of resins are laminated. Although the thickness of the film | membrane 11 is 50 micrometers-100 micrometers, for example, it is not limited to this. The membrane 11 can be folded or unfolded. As a result, the outer package 10 can be freely deformed by folding, unfolding, inflating, deflating, or the like. The outer packet 10 in the first state is three-dimensionalized in a box shape by a shape retaining frame (supporting portion) 20. The outer packet 10 in the second state can be flattened or folded by being released (unsupported) from the shape retaining frame 20.

  An opening 13 is formed at one end (front side in FIG. 3) of the outer packet 10. The opening 13 is directed to the side (front side in FIG. 1). An internal space 19 of the outer packet 10 is continuous with the opening 13. The internal space 19 constitutes a pseudo body cavity corresponding to the body cavity of the human body. The end of the outer packet 10 opposite to the opening 13 (the back side in FIG. 3) is closed by heat sealing or the like. A part or all of the opposite end portion of the outer packet 10 may be opened.

  As shown in FIG. 4, the pseudo tissue 3 is provided in the internal space 19 of the outer packet 10. The pseudo tissue 3 imitates a tissue such as a human organ, and is composed of, for example, a soft resin or rubber, but is not limited thereto, and may be composed of a hard resin or metal. Good. A plurality of types of pseudo-tissues 3 may be prepared corresponding to various organs of the human body.

  As shown in FIG. 1, the main surface 12 that should face the outer packet 10 constitutes a pseudo body surface corresponding to the body surface of the human body. A pseudo incision 15 is formed in the main surface 12. In this embodiment, four pseudo incisions 15 are provided in the outer packet 10. The number of pseudo incisions 15 may be 1 to 3, or 5 or more. As shown in FIG. 4, each pseudo incision 15 is composed of a cylindrical member made of resin having higher rigidity than the outer packet 10. The bottom of the pseudo incision 15 is joined and integrated with the main surface 12 of the outer packet 10 by welding or adhesion. The internal space of the pseudo incision portion 15 passes through the main surface portion 12 and communicates with the internal space 19.

  As shown in FIG.1 and FIG.4, the shape-retaining frame 20 at the time of use of the surgical training apparatus 1 (1st state) is a square frame shape with the upper surface and the bottom face opened. As shown in FIG. 2, the shape retaining frame 20 in the second state can be made more compact than in the first state. Specifically, the shape retaining frame 20 in the second state is disassembled for each of the constituent members 21 to 24. By superimposing these constituent members 21 to 24 on each other, the occupied space can be made smaller than in the first state.

The structure of the shape retaining frame 20 will be described in further detail.
As shown in FIG. 2, the shape retaining frame 20 includes four (plural) frame members 21 to 24 as constituent members. The material of these frame members 21 to 24 is made of hard resin. Therefore, the frame members 21 to 24 are sufficiently higher in rigidity than the outer packet 10. Examples of the hard resin include polypropylene (PP), but are not limited thereto. Each of the frame members 21 to 24 is in the form of a rectangular flat plate or sheet. Preferably, the frame members 21 to 24 are made of plastic cardboard sheets (so-called Pradan). Accordingly, the rigidity of the frame members 21 to 24 can be ensured, and the frame members 21 to 24 can be reduced in weight. The color of the frame members 21 to 24 is translucent or white, but is not limited thereto.
Note that the frame members 21 to 24 may be formed of a plastic molded product having a thickness similar to that of the cardboard.

  As shown in FIG. 3, the frame members 21, 22, 23, and 24 constitute front, rear, left and right walls of the shape retaining frame 20, respectively. The front frame member 21 is formed with a pseudo tissue inlet / outlet 21c. In this embodiment, the longitudinal dimension of the left and right frame members 23, 24 is larger than the longitudinal dimension of the front and rear frame members 21, 22, but the present invention is not limited to this. Moreover, although the dimension of the transversal direction (up-down direction) of the four frame members 21-24 is mutually equal, it is not restricted to this.

  As shown in FIG. 2, slits 21 a to 24 a are formed in at least some of the four frame members 21 to 24. Here, slits 21a, 22a, 23a, and 24a are formed at both ends in the longitudinal direction of the frame members 21, 22, 23, and 24, respectively. The slits 21 a, 22 a, 23 a, and 24 a extend from one side edge of the frame members 21, 22, 23, and 24 in the short side direction to the central part in the short side direction. The slits 21a, 22a of the front and rear frame members 21, 22 and the slits 23a, 24a of the left and right frame members 23, 24 are arranged on the opposite sides in the short direction.

  As shown in FIG. 3, the other frame members intersecting with the frame members are inserted and held in the slits 21 a to 24 a of the frame members 21 to 24, so that the four frame members 21 to 24 are connected to each other. Is assembled. As a result, the frame members 21 to 24 are joined to each other in a separable manner to form a rectangular frame shape as a whole. Specifically, the front end portions of the left and right frame members 23 and 24 are inserted and held in the slits 21 a and 21 a at both ends of the front frame member 21, and the front slits of the left and right frame members 23 and 24 are held. Both end portions of the frame member 21 are inserted and held in 23a and 24a, respectively. The rear ends of the left and right frame members 23 and 24 are inserted and held in the slits 22a and 22a at both ends of the rear frame member 22, respectively, and the rear sides of the left and right frame members 23 and 24 are held. Both ends of the frame member 22 are inserted and held in the slits 23a and 24a, respectively. As shown in FIG. 2, when the surgical training apparatus 1 is not used, the front and rear frame members 21 and 22 are pulled down and the left and right frame members 23 and 24 are pulled up so that the frame members 21 to 24 are They are separated from each other, and the shape retaining frame 20 enters the second state (disassembled state).

  As shown in FIGS. 1 and 3, the shape-retaining frame 20 in the first state has a frame shape, and the shape-retaining frame 20 is wrapped in an outer packet 10 so as to be removable (releasable). Specifically, the shape retaining frame 20 is accommodated in the inner space 19 so as to be removable through the opening 13 of the outer packet 10. By the shape retaining frame 20, the outer packet 10 is held in a swelled state in a box shape. That is, the outer packet 10 is three-dimensionalized. The main surface portion 12 covers the upper surface opening of the shape retaining frame 20 and thus directly covers the internal space 19. Further, the front side frame member 21 is directed to the opening 13 of the outer packet 10. The entrance / exit 21 c is connected to the outside through the opening 13. The pseudo tissue 3 can be taken in and out of the internal space 19 through the opening 13 and the outlet 21 c.

As shown in FIG. 4, the treatment training device 1 is placed on the pseudo treatment table 5 and fixed to the pseudo treatment table 5 with an adhesive tape 4 (fixing means, tension applying means). The pseudo treatment table 5 corresponds to a treatment table and is not particularly limited, and a general desk or table can be used. The adhesive tape 4 is provided at two places (a plurality of places) separated in the front-rear direction on both the left and right sides of the outer packet 10. Each adhesive tape 4 is stuck across the upper surface of the pseudo-treatment table 5 from the side surface portion 14 of the outer packet 10. A certain amount of tension is applied to the main surface portion 12 by pulling the side surface portion 14 of the outer packet 10 downward by the adhesive tape 4. Each side surface portion 14 is inclined so as to move away from the frame members 23 and 24 as it goes downward. Further, the bottom of the front end opening 13 of the outer packet 10 is fixed to the pseudo-treatment table 5 by the adhesive tape 4E. It is preferable that the adhesive tapes 4 and 4E have a required adhesive force and can be easily peeled from the outer packet 10 and the pseudo-treatment table 5 with a certain peeling force.
As a means for fixing the treatment training apparatus 1 to the pseudo treatment table 5, an adhesive may be used instead of the adhesive tapes 4 and 4E. In that case, like the adhesive tape 4, it is preferable that this adhesive has adhesive force and ease of peeling.

An example of a method of using the surgical training apparatus 1 having the above configuration will be described.
As shown in FIG. 3, when using the surgical training apparatus 1, the shape-retaining frame 20 is assembled into a frame shape. The shape retaining frame 20 is accommodated in the outer packet 10. As a result, as shown in FIG. 1, the surgical training apparatus 1 can be in the first state, and the outer package 10 can be three-dimensionalized to secure the volume of the internal space 19, that is, the pseudo body cavity. As shown in FIG. 4, the treatment training device 1 is placed on the pseudo treatment table 5. Next, the treatment training device 1 is fixed to the pseudo treatment table 5 with the adhesive tape 4 and tension is applied to the main surface portion 12. Further, the pseudo tissue 3 is accommodated and set in the pseudo body cavity 19.

Then, the endoscope 2 (surgical instrument) is inserted into the pseudo body cavity 19 through the pseudo incision 15 to train the operation of the endoscope 2. Since the main surface portion 12 is transparent and directly covers the pseudo body cavity 19, the posture and movement of the endoscope 2 can be visually confirmed from the outside. Therefore, it is not necessary to install a camera inside the treatment training apparatus 1. A TV monitor is also unnecessary.
In addition, it is assumed that the endoscope 2 is in contact with the inner peripheral surface of the pseudo incision 15 and the like, and friction is applied. However, by applying tension to the main surface 12 of the outer packet 10 with the adhesive tape 4, It can suppress that the incision part 15 inclines or shakes by the said friction. This can prevent the operability of the endoscope 2 from being hindered.
Furthermore, according to the content of training, the pseudo-tissue 3 can be easily replaced with one corresponding to another organ or the like through the opening 13 and the entrance / exit 21c.

When the training is completed, the endoscope 2 is removed from the pseudo incision 15.
Further, when the treatment training device 1 is cleared, the pseudo tissue 3 is taken out from the pseudo body cavity 19. Moreover, the adhesive tape 4 is peeled off, and the fixed state between the treatment training device 1 and the pseudo treatment table 5 is released. Further, the shape retaining frame 20 is taken out from the outer package 10 and the outer package 10 and the shape retaining frame 20 are separated. Then, the outer packet 10 is folded, the shape retaining frame 20 is disassembled, and the four frame members 21 to 24 are stacked and collected. Thereby, the surgical training apparatus 1 can be made into a compact 2nd state, and accommodation and storage of the surgical training apparatus 1 can be simplified.
Moreover, the treatment training device 1 is sufficiently light compared to the large-scale treatment training device described in Patent Literatures 1 to 3 and the like. Therefore, it can carry easily by setting the treatment training apparatus 1 to a 2nd state. Therefore, the present invention is not limited to a specific place such as a training room or a laboratory, and can be used by bringing it to a venue for external training, for example.
In addition, the treatment training device 1 is extremely inexpensive as compared with the treatment training devices described in Patent Documents 1 to 3 and the like, and does not take up a place for storage, so a large number can be prepared. Therefore, even if it is a seminar of a large number of people, it is possible to give each person the practicing training apparatus 1 and practice it at the same time.
Furthermore, the outer packaging 10 and the shape retaining frame 20 of various sizes can be arranged. Thereby, according to the magnitude | size of the pseudo-tissue 3, the treatment training apparatus 1 of a suitable magnitude | size can be selected and used.

Next, another embodiment of the present invention will be described. In the following embodiments, the same reference numerals are given to the drawings for the same configurations as those described above, and the description is simplified.
FIG. 5 shows a second embodiment of the present invention. The second embodiment is a modification of the outer package. This outer packet 10A has a cylindrical shape with both ends opened. That is, not only the opening 13 is provided at the front end of the outer packet 10A, but also the opening 13A is provided at the back end. Therefore, the frame member 20 can be taken in and out not only from the front of the outer package 10A but also from the back side.

  6 and 7 show a third embodiment of the present invention. The third embodiment is a modification of the shape retaining frame. As shown in FIG. 6, in the shape retaining frame 20X, left and right frame members 23X and 24X are divided into two frame pieces 25 and 25 in the longitudinal direction, respectively. These two frame pieces 25, 25 are connected by a shaft 26 so as to be rotatable. Accordingly, as shown in FIG. 7, the frame member 23X is extended as a whole by arranging the two frame pieces 25, 25 of the frame member 23X in the front-rear direction (FIG. 7A), 2 By superimposing the two frame pieces 25, 25, the frame member 23X can be contracted as a whole ((b) in the figure). Although illustration is omitted, the frame member 24X can be similarly extended or contracted. As shown in FIG. 6, in the shape retaining frame 20X in the first state, the frame members 23X and 24X are extended. As shown in FIG. 7B, in the second state, the frame members 23X and 24X can be made more compact by shrinking them. Therefore, the convenience of storage and carrying can be further enhanced. The shape-retaining frame 20X may be combined with the bag-shaped outer packet 10 (FIG. 1), or may be combined with the cylindrical outer packet 10A (FIG. 5).

  8 to 10 show a fourth embodiment of the present invention. The treatment training device 30 of the fourth embodiment includes a pseudo body surface 31 and a pair of legs (supporting portions) 32 and 32. The pseudo body surface 31 is made of a transparent and hard material and has a rectangular flat plate shape. The material of the pseudo body surface 31 is, for example, an acrylic resin, but is not limited thereto, and may be other resin such as polypropylene or polyethylene, or may be a material other than resin such as glass. One or a plurality of pseudo incisions 38 are formed in the pseudo body surface 31. Each pseudo incision 38 is a circular hole that penetrates the pseudo body surface 31 in the thickness direction. The size (diameter) of the pseudo incision 38 is preferably about 5 mmφ to 15 mmφ in consideration of a general diameter (6 mmφ to 14 mmφ) of an endoscope such as a laparoscope or forceps, but is limited to this. is not. Moreover, the number of pseudo incisions 38, the arrangement position, etc. are not limited to those shown in the figure, and can be set as appropriate. End plates 31e are integrally provided on the lower surfaces of both end portions in the width direction (short direction, left and right in FIGS. 9 and 10) of the pseudo body surface 31, respectively. The end plate 31e is formed in an elongated plate shape, and extends in the longitudinal direction of the pseudo-body surface 31 (the direction orthogonal to the paper surface in FIGS. 9 and 10). This end plate 31e is joined to the pseudo-body surface 31 with an adhesive or the like.

  A pair of leg portions 32 and 32 are provided at both ends in the width direction (short direction) of the pseudo-body surface 31. The leg portions 32 and 32 constitute a support portion that supports the pseudo-body surface 31 so that the pseudo-body surface 31 can be released. Each leg 32 is made of a transparent and hard material, has a rectangular plate shape that is narrower than the pseudo-body surface 31 and has substantially the same length as the pseudo-body surface 31. The longitudinal direction of the leg portion 32 is directed in the same direction as the longitudinal direction of the pseudo body surface 31. The material of the leg portion 32 is acrylic resin, similar to the pseudo body surface 31, but is not limited thereto, and may be other resin such as polypropylene or polyethylene, or may be a material other than resin such as glass. The material may be different from that of the pseudo-body surface 31. An elongated end plate 32e is integrally provided at the upper end portion of the leg portion 32 (the end portion on the connection side with the pseudo body surface 31). The end plate 32 e extends in parallel with the leg portion 32 with its width direction oriented in the thickness direction of the leg portion 32. The end plate 32e is joined to the upper end surface of the leg portion 32 with an adhesive or the like.

  A hinge 33 is sandwiched between the end plate 31 e of the pseudo body surface 31 and the end plate 32 e of the leg portion 32. The hinge 33 includes a pair of hinge plates 33a and 33b and a hinge shaft 33c. The pair of hinge plates 33a and 33b are rotatable relative to each other about the hinge shaft 33c. The axis of the hinge shaft 32 c is directed in the longitudinal direction of the pseudo body surface 31 and the leg portion 32. The first hinge plate 33a is integrally joined to the end plate 31e with an adhesive or the like. The second hinge plate 33b is integrally joined to the end plate 32e with an adhesive or the like. As shown in FIGS. 10A and 10B, the leg portion 32 is connected to the pseudo body surface 31 via the hinge 33 so as to be rotatable between the deployed position and the folded position. Eventually, the treatment training device 30 can be transformed between the first state and the second state. That is, as shown in FIG. 10A, the treatment training device 30 is in the first state by setting the pair of legs 32 to the deployed position, and as shown in FIG. 10B, the pair of legs By setting 32 to the folding position, the treatment training device 30 is in the second state. In the first state, the pseudo body cavity 39 is formed by supporting the pseudo body surface 31 by the legs 32 and 32. The upper portion of the pseudo body cavity 39 is covered with a pseudo body surface 31, and both end portions in the width direction of the pseudo body cavity 39 are closed by the leg portions 32. Further, both ends in the longitudinal direction of the pseudo-body cavity 39 are connected to the outside through an opening 37 (pseudo-tissue entrance / exit) between the pseudo-body surface 31 and the ends of the pair of legs 32, 32 in the longitudinal direction. In the second state, when the support is released, the pseudo body cavity 39 is crushed or disappears, and the treatment training device 30 becomes more compact than the first state.

As shown in FIG. 10A, the leg portion 32 at the deployed position is substantially orthogonal to (intersects) the pseudo-body surface 31. Preferably, an angle θ ₁ (an angle of a corner defined by the pseudo body surface 31 and the leg portion 32 in the pseudo body cavity 39) between the leg portion 32 and the pseudo body surface 31 at the deployed position is more than 90 °. Is slightly larger, specifically, more than 90 ° to 120 ° (90 ° <θ ₁ ≦ 120 °). Accordingly, the pair of leg portions 32 and 32 are inclined so as to be separated from each other toward the lower side (the side opposite to the connection side with the pseudo body surface 31), and have a “C” shape in a front view. At this time, the hinge plates 33a of the hinge 33, 33b if and are superposed, the angle theta ₁ is greater more is restricted. It also serves as a stopper for regulating the rotation angle of the leg portion 32 of the hinge plates 33a and 33b.
When the angle of the leg portion 32 with respect to the pseudo body surface 31 is θ ₁ , rotation may be restricted by contact between the end plates 31 e and 32 e, and the pseudo body surface 31 and the leg portion 32 may be restricted. The rotation may be regulated by directly hitting. The angle θ ₁ formed between the leg portion 32 and the pseudo-body surface 31 at the deployed position may be just 90 ° or may be less than 90 ° to about 70 °.

As shown in FIG. 10B, the leg portion 32 at the folding position is substantially parallel to the pseudo body surface 31 and is along the pseudo body surface 31. That is, the angle θ ₂ formed between the leg portion 32 and the pseudo-body surface 31 is sufficiently small, and preferably close to 0 °. The portions of the pair of leg portions 32, 32 opposite to the connection side with the pseudo body surface 31 are overlapped with each other.

As shown in FIG. 10A, the lower end surface of each leg portion 32 (the end surface opposite to the connection side with the pseudo body surface 31) is inclined with respect to both side surfaces of the leg portion 32. . The angle of the end face θ ₃ has a size corresponding to the angle θ ₁ formed by the leg portion 32 and the pseudo-body surface 31 at the deployed position (θ ₃ = θ ₁ ). Therefore, when the leg 32 is placed on the pseudo-surgical table 5 in the deployed position, the lower end surface of the leg 32 is just parallel to the upper surface of the pseudo-surgical table 5.

  Further, an anti-slip material 34 is provided on the lower end surface of the leg portion 32 (the end surface opposite to the connection side with the pseudo body surface 31). The anti-slip material 34 is made of, for example, a high friction rubber or resin sheet, and is attached to the lower end surface of the leg portion 32 by adhesion or the like. Two anti-slip members 34 are provided at both ends in the longitudinal direction of the lower end surface of each leg 32, but the present invention is not limited to this, and three anti-slip members 34 are provided in the longitudinal direction of the lower end surface of each leg 32. It may be provided as described above, or may be provided over the entire lower end surface of each leg portion 32.

At the same time, the leg portions 32 are placed upright on the pseudo-treatment table 5. Thus, the pseudo body surface 31 is horizontally supported away from the pseudo operation table 5, and a pseudo body cavity 39 is formed between the pseudo body surface 31 and the pseudo operation table 5 below the pseudo body table 31. The pseudo-tissue 3 is inserted into the pseudo-body cavity 39 through the openings 37 before and after the pseudo-body cavity 39 and placed on the pseudo-treatment table 5. Alternatively, the pseudo-tissue 3 may be placed on the pseudo-treatment table 5 and the treatment training device 30 may be placed thereon. Then, the endoscope 2 (the surgical instrument) is inserted into the pseudo body cavity 39 from the pseudo incision portion 38 to perform surgical training. Since the pseudo body surface 31 is transparent, it is possible to easily check the operation status of the endoscope 2 from the outside. In the first state, the pair of leg portions 32, 32 are formed in a “C” shape when viewed from the front, so that the resistance against vertical and lateral loads can be effectively exerted, and the posture of the surgical training apparatus 30 is stabilized. Can be made. Moreover, the slip of the leg part 32 can be prevented by the anti-slip material 34, and the treatment training device 30 can be arranged more stably on the pseudo treatment table 5.

  As shown in FIG. 10 (b), when the surgical training is completed and the surgical training device 30 is cleared, the leg 32 is rotated toward the pseudo body surface 31 to the folding position, and the surgical training device 30 is eventually moved. Set to the second state. Thereby, the treatment training apparatus 30 can be made more compact than the first state. Moreover, the structure is simple and the weight is light. Therefore, the treatment training device 30 can be easily stored, stored, or carried.
