Description

  The present invention relates to a procedure simulator for training a procedure using a catheter and a simulation method using the procedure simulator.

  The peritoneal dialysis method is attracting a great deal of attention because it allows patients to exchange dialysate containers (bags) at home or at work, making it easier to return to society. In this peritoneal dialysis method, one end of a catheter (peritoneal dialysis catheter) is placed in the abdominal cavity of a patient and the other end is placed outside the body, and then dialysate is injected into the abdominal cavity through the lumen of the catheter. In this method, the dialysate is exchanged by discharging the intraperitoneal dialysate through the lumen of the catheter after a certain time has elapsed.

  In order to perform peritoneal dialysis in this way, peritoneal dialysis catheter placement is necessary, but in the education, experiment, practice, etc. to learn the procedure using such a catheter, it should be performed using the human body. I couldn't, so there wasn't anything that I was satisfied with. For this reason, it has been difficult to learn a procedure using a catheter without much clinical experience.

  By the way, as a procedure simulator that gives a simulated experience that approximates an actual procedure by the human body, a human skin substitute (for example, pig skin) and a human organ substitute (for example, porcine trachea) are used for incision of the trachea and abdomen. A technical idea for making a simulated skin suture experience is known (see, for example, Patent Document 1). In addition, a technique simulator for learning a technique for organ surgery performed by incising a chest wall of a patient is known (see, for example, Patent Document 2).

JP 2010-85512 A JP 2001-5378 A

  However, the technique simulator according to Patent Document 1 is for causing a simulated experience of trachea and skin incision and skin suture, and the technique simulator according to Patent Document 2 is for organ surgery performed by incising the chest wall. It is for learning techniques. That is, since the above-described conventional technique does not assume a procedure using a catheter, it is difficult to efficiently acquire a procedure using a catheter even if the procedure simulator is used.

  The present invention has been made in consideration of such problems, and even if it is not based on clinical experience, it is possible to have a simulated experience that approximates the actual procedure by the human body, and the procedure using the catheter is efficient. It is an object of the present invention to provide a technique simulator that can be learned and a simulation method using the same.

[1] A technique simulator according to the present invention is a technique simulator for training a technique using a catheter, and is provided in a hollow torso model corresponding to a torso part of a human body, and provided in the torso model. A space forming means for forming a space corresponding to the abdominal cavity of the human body, and a human abdominal part substitute that can be attached to the torso model, and the torso model has an opening that communicates with the space; fixing means for fixing is provided to the human body abdominal substitute placed so as to cover the opening from the outside with respect to the body model, the space forming means is arranged to the waist of the body model And a deep bottom portion that is connected to the shallow bottom portion and is disposed in a ridge portion of the trunk model and corresponds to a Douglas pit of a human body.

  Since the human body abdominal substitute is used according to the procedure simulator according to the present invention, for example, the sensation of incising the human abdominal substitute approximates the sensation of incising the actual human abdomen (peritoneum and skin). To do. The body model is provided with a space forming means for forming a space corresponding to the abdominal cavity of the human body and an opening communicating with the space is formed in the body model. The feeling of inserting a catheter into the space through the opening is similar to the feeling of inserting a catheter into the abdominal cavity of an actual human body. Thereby, even if it does not depend on a clinical experience, the simulation experience approximated to the actual procedure by the human body can be performed, and the procedure using the catheter can be efficiently learned.

[2] In the above procedure simulator, the human body abdominal substitute is equivalent to the human peritoneum, may have a peritoneal portion ing from the ventral membrane of mammals or birds animals other than humans. According to such a procedure simulator, more approximate to the human body abdominal substitute the actual human abdomen. This makes it possible to perform training that is sensuously close to the actual procedure.

[3] The technique simulator may further include a human body organ substitute disposed in the space formed by the space forming unit. According to such a procedure simulator, since the human organ substitute is disposed in the space formed by the space forming means, the catheter hits the human organ substitute when the catheter is inserted into the space. Become. Thereby, when the catheter is inserted into the abdominal cavity of an actual human body, it is possible to experience a simulation of the sense that the catheter hits the internal organs (intestinal tract).

[4] In the above procedure simulator, a lubricant may be applied to the outer surface of the human organ substitute. According to such a procedure simulator, since the lubricant is applied to the outer surface of the human body organ substitute, the body organ substitute can be made more similar to the internal organs of the actual human body.

[5] In the above procedure simulator, the trunk model and the space forming means may have transparency. According to such a procedure simulator, since the trunk model and the space forming means are transparent, the position of the distal end portion of the catheter inserted into the space formed by the space forming means can be easily visually recognized from the outside. can do. As a result, it is possible to easily know whether or not the distal end of the catheter has reached the target position (for example, the portion corresponding to the Douglas fossa of the human body), so that the training of the procedure using the catheter is more efficient. Can be done automatically.

[6] In the simulation method according to the present invention, a space forming means for forming a space corresponding to the abdominal cavity of the human body is provided in a hollow body model corresponding to the body portion of the human body, and the space model is formed on the body model. A simulation method using a technique simulator in which a human abdominal substitute provided to cover an opening communicating with the body from the outside is fixed to the body model by a fixing means, wherein the space forming means includes the body An incision for incising the human abdominal substitute , comprising: a shallow bottom portion disposed on the waist of the model; and a deep bottom portion connected to the shallow bottom portion and disposed on the buttocks portion of the torso model and corresponding to the Douglas fossa of the human body A step of inserting a catheter into the space through the incision formed in the human abdominal substitute and the opening, and after the insertion step, And a reaching step of causing the tip portion to reach the deep bottom portion .

  According to the simulation method of the present invention, since the incision step of incising the human abdominal substitute is performed, it is possible to experience a sensation that approximates the sense of incising the abdomen (peritoneum and skin) of the actual human body. In addition, the catheter is inserted into the abdominal cavity of an actual human body in order to perform the insertion step of inserting the catheter into the space formed by the space forming means through the incision portion formed in the incision step and the opening of the trunk model You can experience a sensation that approximates your senses. Thereby, even if it is not based on clinical experience, it is possible to have a simulated experience that approximates an actual procedure by a human body, so that it is possible to efficiently acquire a procedure using a catheter.

  As described above, according to the present invention, the space forming means for forming the space corresponding to the abdominal cavity of the human body is provided in the hollow body model corresponding to the body portion of the human body, and the body model communicates with the space. The human body abdominal substitute can be fixed by forming an opening to cover the body model so as to cover the opening from the outside, so that it approximates to the actual procedure by the human body without using clinical experience And can learn the technique using a catheter efficiently.

  DESCRIPTION OF EMBODIMENTS Hereinafter, a technique simulator according to the present invention will be described with reference to the accompanying drawings by giving a preferred embodiment example in relation to a simulation method using the same.

  The procedure simulator 10 according to an embodiment of the present invention is for training a procedure using the peritoneal dialysis catheter 200, and is used in a state where the human abdominal substitute 100 is attached.

  First, the human body abdomen substitute 100 will be described. As shown in FIG. 1, the human abdominal substitute 100 is incised and sutured during the simulation of the procedure using the peritoneal dialysis catheter 200. Therefore, every time the simulation is performed once to several times, a new human body is obtained. Replaced with abdominal substitute. Therefore, in this embodiment, the procedure simulator 10 does not include the human body abdomen substitute 100. However, the procedure simulator 10 may include the human body abdomen substitute 100.

  The human body abdomen substitute 100 has a peritoneum 102 corresponding to the peritoneum of the human body and a skin 104 corresponding to the skin of the abdomen of the human body. As such a human body abdomen substitute 100, for example, the abdomen of mammals other than humans such as pigs and cattle or avian animals such as chickens can be used, and the abdomen of pigs is particularly preferable. This is because the abdomen of pigs is inexpensive and excellent in availability, and its structure and tissue are similar to those of the human abdomen. In this embodiment, an example in which a pig abdomen is used as the human abdomen substitute 100 will be described. The human abdominal part substitute 100 may be composed of, for example, a peritoneum part of a mammal such as a pig or a cow, and an artificial skin covering the peritoneum part.

  The procedure simulator 10 includes a support 12, a hollow body model 14 corresponding to the body part of the human body, and a container (space formation) that is disposed inside the body model 14 and forms a space S corresponding to the abdominal cavity of the human body. Means) 16, an intestinal tract model (human organ substitute) 18 disposed in the container 16, and a plurality of fixing pins (fixing means) 20 for fixing the human abdominal substitute 100 to the trunk model 14. With.

  The support base 12 is for mounting the trunk model 14, and may include a fixing means (not shown) that fixes the trunk model 14 in a mounted state. In this case, it is possible to prevent the trunk model 14 from moving with respect to the support base 12 during the simulation using the procedure simulator 10.

  As shown in FIGS. 2 and 3, the trunk model 14 can be made of, for example, a relatively hard resin material, and has transparency (translucency). That is, the body model 14 of this embodiment can visually recognize the inside from the outside. The torso model 14 can be appropriately set in dimensions for children and adults.

  An opening 22 having a substantially trapezoidal shape (see FIG. 2) in plan view is formed in the center of the abdomen of the trunk model 14. The opening 22 can be set to an arbitrary size. For example, if the opening 22 is formed over substantially the entire center of the abdomen of the torso model 14, the incision of the human abdomen substitute 100, the insertion of the peritoneal dialysis catheter 200, etc. The wall part etc. which comprise the said opening part 22 do not become obstructive.

  A plurality of through holes 24 are formed in the body model 14 at substantially equal intervals along the entire circumference of the edge of the opening 22. The diameter of each through-hole 24 is set to a dimension that allows the fixing pin 20 to be inserted. A long hole 26 extending along the longitudinal direction of the trunk model 14 is formed on both sides of the trunk model 14. That is, in the trunk model 14 of the present embodiment, the opening 22 is located between the pair of long holes 26.

  The container 16 has a certain degree of flexibility and can be made of, for example, a resin material such as silicone. As a result, the container 16 can be easily inserted into the body model 14 through the opening 22 of the body model 14 while being bent. The container 16 is maintained in a predetermined shape in the body model 14. The container 16 has transparency (semi-transparency), and includes a bottom portion 28, a side wall portion 30 erected from the entire edge of the bottom portion 28, and a pair of locking portions provided on the outer surface of the side wall portion 30. 32.

  The bottom portion 28 has a gently curved shape, and includes a shallow bottom portion 28a disposed on the waist portion 14a of the trunk model 14, and a deep bottom portion 28b connected to the shallow bottom portion 28a and disposed on the ridge portion 14b of the trunk model 14. (See FIG. 3). The deep bottom portion 28b is a portion where the dialysate L (see FIG. 16) easily accumulates, and corresponds to the Douglas pit of the human body.

  A substantially inverted U-shaped cutout 34 in plan view is formed at the center in the width direction at the end of the deep bottom 28b opposite to the shallow bottom 28a (see FIG. 4). That is, a pair of projecting portions 30 a and 30 b are formed on the side wall portion 30 so as to sandwich the notch portion 34. The notch 34 is set to a size that allows the crotch portion 14c of the body model 14 to be disposed.

  Accordingly, the pair of projecting portions 30a and 30b are formed in the crotch portion 14c of the trunk model 14 in a state where the container 16 is disposed in the trunk model 14 so that the cutout portion 34 is located in the crotch portion 14c of the trunk model 14. Since the container 16 approaches or comes into contact, it is possible to suitably suppress the relative movement of the container 16 relative to the trunk model 14 along the width direction.

  As can be understood from FIGS. 2 and 3, the space S (the space corresponding to the abdominal cavity of the human body) inside the container 16 is provided in the opening 22 of the torso model 14 while being disposed in the torso model 14. Communicate.

  Each locking portion 32 is formed by fixing the belt-shaped member to the side wall portion 30 in a state of being bent in a substantially C shape. Each locking portion 32 protrudes outside the trunk model 14 from each long hole 26 of the trunk model 14 in a state where the container 16 is disposed in the trunk model 14. Thereby, the relative displacement of the trunk | drum model 14 and the container 16 along the longitudinal direction of the trunk | drum model 14 can be suppressed. That is, each of the locking portions 32 and each of the long holes 26 functions as a restricting unit that restricts the relative displacement between the body model 14 and the container 16.

  The intestinal tract model 18 is formed by connecting a plurality of single intestine models 18a in a row. Each single intestine model 18a is filled with a liquid (for example, water). As a result, the intestinal tract model 18 can be made to have substantially the same weight as the actual human intestinal tract. In addition, each single intestine model 18a is preferably made of a material (for example, rubber or the like) that is torn and liquid inside leaks when a force that damages the intestinal tract of an actual human body is applied. Such an intestinal tract model 18 can be formed, for example, by connecting a plurality of long thin water balloons in a row. In this case, the intestinal tract model 18 can be obtained at low cost.

  Further, a lubricant is applied to the outer surface of the intestinal tract model 18. As the lubricant, for example, an anionic, nonionic, cationic, or amphoteric surfactant can be used. Thereby, the intestinal tract model 18 can be further approximated to the actual intestinal tract of the human body.

  Each fixing pin 20 is configured by, for example, a metal rod having a tapered tip. These fixing pins 20 can be inserted into any through hole 24 in a state where the human abdomen substitute 100 is penetrated. Thereby, the human body abdomen substitute 100 can be fixed to the trunk model 14.

  The procedure simulator 10 according to the present embodiment is basically configured as described above. Next, a procedure for fixing the human body abdomen substitute 100 to the procedure simulator 10 will be described.

  As shown in FIG. 5, first, the human body abdomen substitute 100 is disposed on the torso model 14 so as to cover the opening 22 of the torso model 14 fixed to the support 12. Then, in a state where an appropriate tension is applied to the human body abdomen substitute 100, the human body abdomen substitute 100 is fixed to each locking portion 32 with a fixing thread 36 or the like (see FIG. 6). Thereby, since the human body abdomen substitute 100 is maintained in a state where a predetermined tension is applied, the human body abdomen substitute 100 can be made more approximate to the abdomen of the actual human body.

  Subsequently, each fixing pin 20 is inserted into the human body abdomen substitute 100 and inserted into the through hole 24 of the trunk model 14. At this time, since the trunk model 14 has transparency, it can be easily confirmed by visual observation from the outside whether each fixing pin 20 is inserted through the through hole 24.

  In the present embodiment, six fixing pins 20 are used for the twelve through holes 24. As described above, by setting the number of the through holes 24 to be larger than the number of the fixing pins 20 (for example, twice the number), the piercing position of the fixing pin 20 with respect to the human abdominal substitute 100 is a through hole. Even if the position is slightly deviated from the position 24, the fixing pin 20 can be reliably inserted into the through hole 24. However, the numbers of the fixing pins 20 and the through holes 24 may be arbitrarily set.

  Further, as a method of fixing the human abdominal substitute 100 to the torso model 14, in addition to the present embodiment, six openings 106 are provided on the periphery of the human abdominal substitute 100 and a fixing belt (not shown) is passed, A method of fixing the fixing belt to the six fixing portions 25 provided at positions away from the opening 22 (see FIG. 1) of the trunk model 14 may be used. In this case, by adjusting the length of the fixing belt, it is possible to easily adjust the tension applied to the human abdominal substitute 100. Therefore, it is possible to secure a wider surgical field than when the fixing pin 20 is used. it can.

  Next, a simulation method using the procedure simulator 10 according to the present embodiment will be described. In this embodiment, an example of a simulation method for training a procedure using a peritoneal dialysis catheter (hereinafter simply referred to as “catheter”) 200 will be described with reference to FIGS.

  First, as shown in FIG. 8, the positions of the inner cuff 202 and the outer cuff 204 of the catheter 200 are marked on the outer surface of the human abdominal substitute 100 fixed to the torso model 14 by the fixing method described above (step of FIG. 7). S1). In this embodiment, a swan neck type catheter is used as the catheter 200. However, the present invention is not limited to this, and for example, a straight type catheter may be used.

  Thereafter, the first marking portion M1 corresponding to the internal cuff 202 is incised using an electric knife (medical instrument) (step S2). That is, the peritoneum 102 and the skin 104 of the human body abdominal substitute 100 are incised with an electric knife. At this time, four edge portions constituting the peritoneal incision 70 may be held by mosquito forceps (not shown).

  Then, a metal rod-shaped stylet 206 coated with a lubricant is passed through the lumen of the catheter 200, and the distal end side of the catheter 200 is the skin incision 72, the peritoneal incision 70, and the opening of the first marking portion M1. It inserts in the space S inside the container 16 through the part 22 (refer step S3, FIG.9 and FIG.10).

  Subsequently, the user (trainer) holds the ring portion 206a of the stylet 206 and operates the catheter 200, so that the distal end portion of the catheter 200 becomes the deep bottom portion 28b of the container 16 (the portion corresponding to the Douglas fossa of the human body). (Step S4).

  At this time, the user can experience the simulation when the catheter 200 contacts the actual intestinal tract of the human body by the catheter 200 contacting the intestinal tract model 18. Moreover, since the lubricant is applied to the outer surface of the intestinal tract model 18, the feeling that the catheter 200 is in contact with the intestinal tract model 18 is very close to the feeling when the catheter 200 is in contact with the actual intestinal tract of the human body.

  Furthermore, when the force applied from the catheter 200 to the intestinal tract model 18 is too strong, a part of the intestinal tract model 18 is broken and the liquid inside leaks out. By doing so, it is possible to experience whether the actual human intestinal tract is damaged.

  Moreover, since the trunk | drum model 14 and the container 16 have transparency, a user can visually confirm from the outside whether the front-end | tip part of the catheter 200 reached | attained the deep bottom part 28b of the container 16 easily. Can do.

  Next, the user removes the stylet 206 from the catheter 200 and sutures and fixes the internal cuff 202 to the peritoneum 102 with the absorbable suture 74 (see step S5, FIG. 11). Suture is performed with the absorbable suture 75 (step S6, FIG. 12). At the stage where the peritoneum portion 102 has been sutured, the rear end side of the catheter 200 is exposed to the outside from the upper end of the suture portion of the peritoneum portion 102. In this step S6, as shown in FIGS. 11 and 12, the Penrose drain 76 may be inserted in the vicinity of the internal cuff 202 when the incised peritoneum portion 102 is sutured.

  Subsequently, the second marking portion M2 corresponding to the external cuff 204 is opened with an electric knife (step S7). That is, only the skin 104 of the human abdominal substitute 100 is incised with an electric knife.

  Then, the rear end side of the catheter 200 is guided between the peritoneum 102 and the skin 104 of the human abdominal substitute 100 and the skin incision 78 of the second marking portion M2 by a trocar (not shown) (see step S8, FIG. 12).

  Next, the collagen cuff 80 is attached in the vicinity of the rear end side of the outer cuff 204 of the catheter 200, and the rear end portion of the catheter 200 is guided to a predetermined position through the space between the peritoneum 102 and the skin 104 of the human abdominal substitute 100, It is exposed to the outside of the skin 104 (see step S9, FIG. 13). Thereafter, the outer cuff 204 is sutured and fixed to the peritoneum 102 with the absorbent suture 82 in a state where the outer cuff 204 is disposed in the skin incision 78 (step S10).

  Subsequently, the skin 104 of the human abdominal substitute 100 is sutured with the sutures 84 and 86 so that each of the skin incision 72 and the skin incision 78 is completely closed (step S11, see FIG. 14). In this state, the rear end portion of the catheter 200 is exposed to the outside of the human abdominal substitute 100.

  Then, a bifurcated connecting tube 88 is connected to the rear end of the catheter 200, and a dialysate bag 90 filled with dialysate L is attached to one end of the bifurcated connecting tube 88. An empty dialysate collection bag 92 is attached to the other end (step S12).

  Next, the clamp 94 on the dialysate bag 90 side is opened and the clamp 96 on the dialysate collection bag 92 side is closed to allow the catheter 200 and the dialysate bag 90 to communicate with each other, and between the catheter 200 and the dialysate collection bag 92. With the communication blocked, the dialysate L in the dialysate bag 90 is injected into the space S inside the container 16 through the connection tube 88 and the catheter 200 (see step S13, FIG. 15).

  After the injection of the dialysate L is completed, the clamp 94 on the dialysate bag 90 side is closed and the clamp 96 on the dialysate collection bag 92 side is opened to block communication between the catheter 200 and the dialysate bag 90. With the catheter 200 and the dialysate recovery bag 92 communicated, the dialysate L in the container 16 is recovered into the dialysate recovery bag 92 via the catheter 200 and the connection tube 88 (step S14, FIG. 16).

  At this time, as can be understood from FIG. 16, when the amount of dialysate L in the container 16 decreases, the dialysate L collects in the deep bottom portion 28 b of the container 16 corresponding to the Douglas pit of the human body. Since the portion is located at the deep bottom portion 28b, the dialysate L can be recovered in the dialysate recovery bag 92 without leaving the dialysate L. This simulation is completed when the recovery of the dialysate L is completed.

  According to the present embodiment, since the human abdominal substitute 100 is fixed to the torso model 14, the sense of incising the human abdominal substitute 100 cuts the abdomen (peritoneum and skin) of the actual human body. Approximate to the senses.

  Further, since the container 16 that forms the space S corresponding to the abdominal cavity of the human body is disposed in the torso model 14 and the opening 22 that communicates with the space S is formed in the torso model 14, the skin incision 72, The feeling of inserting the catheter 200 into the space S through the peritoneal incision 70 and the opening 22 approximates the feeling of inserting the catheter 200 into the actual abdominal cavity of the human body. Thereby, even if it does not depend on a clinical experience, the simulation experience approximated to the actual procedure by a human body can be performed, and the procedure using the catheter 200 can be acquired efficiently.

  In the present embodiment, since the human abdominal substitute 100 uses the abdomen of a pig which is a mammal other than a human, the human abdominal substitute 100 is more similar to the abdomen of an actual human body. This makes it possible to perform training that is sensuously close to the actual procedure.

  In addition, since the intestinal tract model 18 is disposed in the container 16, the catheter 200 hits the intestinal tract model 18 when the catheter 200 is inserted into the space S inside the container 16. Thereby, when the catheter 200 is inserted into the abdominal cavity of an actual human body, it is possible to experience a simulation of the feeling that the catheter 200 hits the internal organs (intestinal tract). Furthermore, since the lubricant is applied to the outer surface of the intestinal tract model 18, the intestinal tract model 18 can be more closely approximated to an internal organ (intestinal tract) of an actual human body.

  According to this embodiment, since the trunk model 14 and the container 16 have transparency, the position of the distal end portion of the catheter 200 inserted into the space S formed by the container 16 can be easily visually recognized from the outside. be able to. This makes it possible to easily know whether or not the distal end portion of the catheter 200 has reached the deep bottom portion 28b of the container 16 (the portion corresponding to the Douglas fossa of the human body). Training can be performed more efficiently.

  The present invention is not limited to the above-described embodiment, and it is naturally possible to adopt various configurations without departing from the gist of the present invention.

  For example, the procedure simulator according to the present invention may include a hollow human body model (whole body model) corresponding to the whole body of the human body instead of the torso model.
