Conventional surgical training devices such as the above-mentioned publications are bulky and inconvenient to carry.
Therefore, the applicant of the present application has proposed a surgical training apparatus having a plate-like pseudo-body surface and a pair of legs that can be expanded and folded in the previous application (Japanese Patent Application No. 2013-177930). At the time of use (training), the pair of legs are expanded and stood substantially vertically, thereby supporting the pseudo body surface horizontally and creating a pseudo body cavity between the pseudo body surface and the pair of legs. When carrying or storing, the legs are folded along the bottom surface of the pseudo body surface. As a result, the treatment training apparatus can be made compact and easy to carry and store.
However, in use, when a surgical instrument such as forceps is inserted into the pseudo surgical hole in the pseudo body surface, the side of the surgical instrument hits the inner peripheral surface of the pseudo surgical hole, and the leg portion is likely to wobble.
In view of the above circumstances, the present invention is a surgical training apparatus having a pseudo body surface and a pair of legs that can be expanded and folded, so that the surgical training can be performed without hindrance by suppressing wobble during use. Is to make it.

The present invention is a surgical training apparatus for training the operation of a surgical instrument inserted into a human body,
A training apparatus body, and a support base that releasably supports the training apparatus body,
The training apparatus main body is rotatable between a hard plate-like pseudo body surface in which pseudo operation holes of the surgical instrument are formed and left and right ends of the pseudo body surface between a deployed position and a folded position. A pair of left and right legs connected to each other, the leg at the deployed position intersects the pseudo body surface, and the leg at the folded position is along the pseudo body surface,
The support base includes a pedestal and left and right holding members that are detachably attached to the left and right ends of the pedestal, respectively, and the holding member is opposite to the pseudo body surface of the leg portion in the deployed position. The side end portion is releasably held.

According to this surgical training apparatus, the left and right legs of the training apparatus main body are respectively set in the deployed position and supported by the support base, thereby imitating the body cavity of the human body between the pseudo body surface, the left and right legs, and the base. A simulated body cavity can be formed. Then, a surgical instrument such as forceps or an endoscope is inserted into the pseudo body cavity from the pseudo surgical hole to perform surgical training. At this time, even if a surgical instrument such as forceps hits the inner peripheral surface of the pseudo surgical hole, the holding member holds the leg, thereby suppressing or preventing the leg from wobbling. Therefore, surgical training can be performed without hindrance.
When the treatment training apparatus is not used, the training apparatus main body and the support base can be separated by releasing the legs from the holding member. Moreover, a training apparatus main body can be made compact by making a leg part into a folding position. Furthermore, the treatment training apparatus can be made more compact by separating the pedestal of the support base and the holding member. Therefore, the treatment training apparatus can be easily stored and stored, and can be easily carried.

It is preferable that the pseudo body surface is inclined in the front-rear direction by holding the leg portion by the holding member.
Thereby, the pseudo body surface can be made to resemble the state of the lower abdomen inflated with gas or the like for, for example, laparoscopic surgery, and the effectiveness of surgical training can be enhanced.

Four holding members are disposed at the four corners of the pedestal so as to protrude upward, the front left and right holding members have a relatively small protruding height, and the rear left and right holding members have a relatively protruding height. It is preferable that the leg portion is held at the upper end portion of each holding member.
Thereby, even if the pseudo body surface is horizontal when there is no support base, the pseudo body surface can be inclined in the front-rear direction by using the support base. In addition, by using four holding members, the support base can be further disassembled and made compact.

A base fitting groove into which the end of the pedestal is fitted is formed in the lower part of the side surface of the holding member, and a leg fitting groove into which the end of the leg is fitted is formed in the upper surface of the holding member. It is preferable.
Thus, the holding member can be easily attached to and detached from the pedestal, and the leg portion can be easily attached to and detached from the holding member.

The holding member is made of an elastic material, and in the natural state of the holding member, the thickness of the base fitting groove is smaller than the thickness of the end of the base, and the thickness of the leg fitting groove is The thickness is preferably smaller than the thickness of the end of the leg.
Accordingly, the holding member can be securely attached to the pedestal by the elastic force. Further, the leg portion can be firmly held by the elastic force of the holding member. Therefore, the wobble at the time of use can be suppressed more reliably.

  According to the surgical training apparatus of the present invention, surgical training can be performed without hindrance by suppressing wobble during use.

As shown in FIG. 6, the pseudo body surface 11 has a plurality of pseudo treatment holes 15 formed therein. Each pseudo treatment hole 15 is a circular or elliptical hole penetrating the pseudo body surface 11 in the thickness direction. The size of the pseudo operation hole 15 is set in consideration of a general diameter (about 3 mmφ to 15 mmφ) of an endoscope such as a laparoscope and forceps. For example, the diameter of the circular pseudo surgical hole 15 is preferably about 5 mmφ to 20 mmφ, the major axis of the elliptical pseudo surgical hole 15 is preferably about 10 mm to 30 mm, and the minor axis is preferably about 5 mm to 20 mm, but is not necessarily limited thereto. It is not a thing. The placement position of the pseudo surgical hole 15 is set in consideration of the position of the hole formed in the abdomen for laparoscopic surgery, for example.
Note that the number, shape, size, arrangement position, and the like of the pseudo surgical holes 15 are not limited to those illustrated, and can be set as appropriate.

  As shown in FIG. 2, ear plates 11 e are integrally provided on the lower surfaces of the left and right ends of the pseudo-body surface 11. The ear plate 11e is formed in an elongated plate shape and extends in the front-rear direction (left and right in FIG. 2). The ear plate 11e is joined to the pseudo-body surface 11 with an adhesive or the like.

  As shown in FIG. 1, leg portions 12 are provided at both left and right ends of the pseudo-body surface 11. The pseudo body surface 11 is supported between the pair of leg portions 12 and 12 so as to be bridged. The leg 12 is made of a transparent and hard material. For example, the material of the leg portion 12 is an acrylic resin as in the pseudo-body surface 11, but is not limited thereto, and may be another resin such as polypropylene or polyethylene, or a material other than a resin such as glass. Alternatively, a material different from that of the pseudo-body surface 11 may be used.

  As shown in FIG. 3, the leg portion 12 has a rectangular plate shape that is narrower than the pseudo-body surface 11 and has substantially the same length as the pseudo-body surface 11. The longitudinal direction of the leg portion 12 is directed in the front-rear direction so as to follow the longitudinal direction of the pseudo body surface 11. An elongated ear plate 12e is integrally provided at the upper end portion of the leg portion 12 (the end portion on the connection side with the pseudo body surface 11). The ear plate 12 e extends along the upper end portion of the leg portion 12 while making the width direction orthogonal to the width direction of the leg portion 12. The ear plate 12e is joined to the upper end surface of the leg portion 12 with an adhesive or the like.

  As shown in FIG. 5, a hinge 13 is sandwiched between the ear plate 11 e of the pseudo body surface 11 and the ear plate 12 e of the leg portion 12. The leg portion 12 is connected to the pseudo-body surface 11 via a hinge 13 so as to be rotatable between a deployed position (FIG. 4) and a folded position (FIG. 5).

  As shown in FIG. 1, the leg 12 at the deployed position intersects (substantially orthogonally) the pseudo-body surface 11 and has a substantially vertical upright posture. The angle (inner angle) formed between the leg 12 at the deployed position and the pseudo-body surface 11 is preferably about 90 ° to 120 °, and more preferably about 90 °. As shown in FIG. 2, when the pair of plates 13 a and 13 b of the hinge 13 are overlapped with each other at the deployed position, the angle of the leg portion 12 with respect to the pseudo-body surface 11 is restricted from being further increased. The hinge 13 also functions as a stopper that regulates the rotation angle of the leg 12.

  As shown in FIG. 1, the leg portions 12, 12 in the deployed position are supported from below by a support base 20, so that the treatment training device 1 is in a paired state, and a pseudo body cavity 19 is formed therein. The upper part of the pseudo body cavity 19 is covered with the pseudo body surface 11, and both the left and right side parts of the pseudo body cavity 19 are partitioned from the outside by the legs 12. The bottom of the pseudo-body cavity 19 is defined by the support base 20. Further, as shown in FIGS. 2 and 3, the front and rear sides of the paired treatment training device 1 are opened by front and rear edges of the pseudo body surface 11, the pair of legs 12, 12 and the support base 20. A portion 17 (pseudo tissue entrance / exit) is formed. The pseudo body cavity 19 is opened to the outside through these openings 17.

  As shown in FIG. 5, the leg 12 at the folding position is substantially parallel to the pseudo-body surface 11. And the part on the opposite side to the connection side with the pseudo | simulation body surface 11 in a pair of leg parts 12 and 12 mutually overlaps. Thereby, the pseudo body cavity 19 is crushed or disappears, and the training apparatus body 10 becomes compact.

  As shown in FIG.1 and FIG.2, the support stand 20 supports the training apparatus main body 10 at the time of use of the treatment training apparatus 1 (at the time of treatment training), a base 21, and four holding members on the front, back, left, and right 22 and 23. The pedestal 21 has a flat plate shape. The material of the base 21 is a resin such as a vinyl chloride resin, but may be a metal. The pedestal 21 may be colored or transparent.

  As shown in FIG. 8, square fitting recesses 21 e are formed on the back surfaces (the bottom surface, the front surface in FIG. 8) of the front, rear, left and right end portions (four corners) of the base 21. Each fitting recess 21e reaches two end surfaces of the pedestal 21 that intersect each other. As a result, the four corners of the pedestal 21 are thin fitting portions 21f.

  A tape-shaped or film-shaped anti-slip material 24 is provided at the center of the back surface of the base 21. The anti-slip material 24 is preferably made of a material having a large coefficient of static friction with respect to the pseudo-treatment table 5 (FIG. 1), such as a thermoplastic elastomer.

As shown in FIG. 7A, holding members 22 are detachably attached to the left and right ends of the front side of the base 21, respectively. As shown in FIG. 7B, holding members 23 are detachably attached to the left and right ends of the rear side of the base 21, respectively. The holding members 22 and 23 preferably have elasticity, and further preferably have a high coefficient of static friction with respect to the base 21, the leg portion 12, and the pseudo treatment table 5. Examples of the material of the holding members 22 and 23 include rubber.
The material of the holding members 22 and 23 is not limited to rubber, and may be a resin having appropriate elasticity.

  As shown in FIG. 4, each holding member 22 on the front side has a substantially quadrangular prism shape. A base fitting groove 22 e is formed in the lower portion of the holding member 22. The base fitting groove 22e has a horizontal cut shape, and is open on the surface (one side surface) facing the inner side in the left-right direction of the holding member 22 and the front and rear side surfaces. The thickness (vertical dimension) of the base fitting groove 22e in the natural state of the holding member 22 is slightly smaller than the thickness of the fitting portion 21f of the base 21.

A leg fitting groove 22 d is formed in the upper portion of the holding member 22. The leg fitting groove 22d has a cut shape that extends vertically and front and rear, and opens on the upper surface and front and rear side surfaces of the holding member 22. The thickness (right and left dimension) of the leg fitting groove 22d in the natural state of the holding member 22 is slightly smaller than the thickness of the lower end portion of the leg portion 12 (the end portion on the side opposite to the connection side with the pseudo body surface 11). Small.
Here, the natural state of the holding member 22 refers to a state in which the holding member 22 is separated from the base 21 and the training apparatus main body 10.

  As shown in FIG. 7A, left and right fitting portions 21 f on the front side of the base 21 are fitted in the table fitting grooves 22 e of the left and right holding members 22, respectively. As a result, the holding member 22 is mounted on the pedestal 21 so as to protrude upward from the pedestal 21. Since the thickness of the fitting portion 21f is slightly larger than the table fitting groove 22e, the upper and lower portions sandwiching the table fitting groove 22e in the holding member 22 strongly hold the fitting portion 21f. The lower surface of the holding member 22 is substantially flush with the lower surface (back surface) of the base 21 or slightly protrudes downward. Further, the lower end portion of the leg portion 12 is fitted in the leg fitting groove 22 d of each holding member 22. Since the thickness of the leg portion 12 is slightly larger than the leg fitting groove 22d, both portions sandwiching the leg fitting groove 22d of the holding member 22 strongly sandwich the lower end portion of the leg portion 12.

  As shown in FIG. 4, each holding member 23 on the rear side has a substantially quadrangular prism shape that is longer than the holding member 22 in the vertical direction. A base fitting groove 23 e is formed in the lower portion of the holding member 23. The base fitting groove 23e has a horizontal cut shape, and is open on the surface (one side surface) facing the inner side in the left-right direction of the holding member 23 and the front and rear side surfaces. The thickness (vertical dimension) of the base fitting groove 23e in the natural state of the holding member 23 is slightly smaller than the thickness of the fitting portion 21f of the base 21.

A leg fitting groove 23 d is formed in the upper portion of the holding member 23. The leg fitting groove 23d has a cut shape extending vertically and front and rear, and is open on the upper surface and front and rear side surfaces of the holding member 23. The thickness (the dimension in the left-right direction) of the leg fitting groove 23 d in the natural state of the holding member 23 is slightly smaller than the thickness of the lower end portion of the leg portion 12.
Here, the natural state of the holding member 23 means a state in which the holding member 23 is separated from the base 21 and the training apparatus main body 10.

  As shown in FIG. 7B, the left and right fitting portions 21f on the rear side of the pedestal 21 are fitted in the table fitting grooves 23e of the left and right holding members 23, respectively. Thus, the holding member 23 is mounted on the pedestal 21 so as to protrude upward from the pedestal 21. The protruding height of the holding member 23 is larger than the protruding height of the holding member 22. Further, since the thickness of the fitting portion 21f is slightly larger than the table fitting groove 23e, the upper and lower portions sandwiching the table fitting groove 23e in the holding member 23 strongly hold the fitting portion 21f. The lower surface of the holding member 23 protrudes substantially or flush with the lower surface (back surface) of the base 21. Further, the lower end portion of the leg portion 12 is fitted into the leg fitting groove 23 d of each holding member 23. Since the thickness of the leg portion 12 is slightly larger than the leg fitting groove 23d, both portions sandwiching the leg fitting groove 23d in the holding member 23 strongly sandwich the lower end portion of the leg portion 12.

As shown in FIG. 2, since the height of the holding member 22 is relatively small and the height of the holding member 23 is relatively large, the training apparatus main body 10 and therefore the pseudo body surface 11 are forward (left in FIG. 2). It is inclined in the front-rear direction so as to become lower as it goes. Angle theta ₁₁ relative to the horizontal plane of the mimetic table 11 is, for example, 0 ° <θ ₁₁ ≦ 90 ° C., preferably theta ₁₁ = 15 ° approximately.

The treatment training device 1 is assembled and used as follows, for example.
As shown by a two-dot chain line in FIG. 4, holding members 22 and 23 are attached to the four corners of the base 21, respectively. At this time, the fitting portion 21f is press-fitted into the table fitting grooves 22e and 23e while the table fitting grooves 22e and 23e are slightly expanded by the fitting portion 21f. Accordingly, the lower portions of the holding members 22 and 23 can be elastically pressed against both surfaces of the fitting portion 21f. In addition, the holding members 22 and 23 have a large static friction coefficient with respect to the base 21. Accordingly, the holding members 22 and 23 can be stably attached to the base 21.

  In addition, as shown in FIG. 3, the pair of leg portions 12, 12 is set to the deployed position and is held by the holding members 22, 23. At this time, the leg fitting grooves 22d and 23d are slightly expanded by the lower end portion of the leg portion 12, and the lower end portion of the leg portion 12 is press-fitted into the leg fitting grooves 22d and 23d. Accordingly, the upper portions of the holding members 22 and 23 can be elastically pressed against both surfaces of the lower end portion of the leg portion 12. Moreover, the holding members 22 and 23 have a large static friction coefficient with respect to the leg portion 12. Therefore, the leg portions 12 and 12 can be stably held by the holding members 22 and 23, and the upright posture of the leg portions 12 and 12 can be maintained. As a result, the training apparatus body 10 can be stably supported by the support base 20.

As shown in FIG. 1, this treatment training device 1 is placed on a pseudo treatment table 5. A large static frictional resistance acts on the pseudo-treatment table 5 by directly contacting the lower surfaces of the anti-slip material 24 and the holding members 22 and 23. Thereby, it is possible to reliably prevent the surgical training apparatus 1 from slipping, and the surgical training apparatus 1 can be stably placed on the pseudo surgical table 5.
Further, the pseudo tissue 3 is inserted into the pseudo body cavity 19 from the front and rear openings 17 and is set on the pedestal 21. Alternatively, the pseudo tissue 3 may be placed on the pedestal 21 first, and the training apparatus main body 10 may be placed thereon.

  Then, the surgical instrument 2 is inserted into the pseudo body cavity 19 through the pseudo surgical hole 15 to perform surgical training. At this time, even if the surgical instrument 2 hits the inner peripheral surface of the pseudo-body cavity 19, it is possible to suppress the wobbling of the training apparatus main body 10 by holding the legs 12, 12 firmly by the support base 20 and maintaining the upright posture, or Can be prevented. Therefore, surgical training can be performed without hindrance.

Furthermore, since the pseudo body surface 11 is inclined in the front-rear direction, the pseudo body surface 11 can be made to resemble the lower abdomen in a state inflated with gas or the like for laparoscopic surgery. Thereby, the effectiveness of the treatment training can be enhanced.
By making the protruding heights of the front and rear holding members 22 and 23 different from each other, the pseudo-body surface 11 can be reliably inclined.

Moreover, since the pseudo-body surface 11 is transparent, the operation status of the surgical instrument 2 can be easily confirmed visually from the outside.
Or you may install the camera in the opening part 17 of the front side or the back side, image | photograph the inside of the pseudo body cavity 19, and operate the treatment tool 2 while watching the image | video on a monitor.

As shown in FIG. 4, at the end of the treatment training or when the treatment training device 1 is not used, the training device main body 10 and the support base 20 are removed by pulling and releasing the leg 12 from the leg fitting grooves 22d and 23d. Can be easily separated. Moreover, as shown in FIG. 5, the training apparatus main body 10 can be made compact by rotating the leg part 12 to a folding position. Furthermore, about the support stand 20, the treatment training apparatus 1 can be made still more compact by pulling out the holding members 22 and 23 from each fitting part 21f, and isolate | separating the base 21 and the four holding members 22 and 23.
