  The drawings used in the following description assume the practice of anastomosing the real organ to the gastrointestinal tract, but the present invention is not limited to this, and learns techniques necessary for various organ surgery. It can be used for practice.

The structure of Example 1 of the surgery practice kit which concerns on embodiment of this invention, its effect | action, and an effect are demonstrated concretely using FIGS. 1-4.
FIG. 1 is a perspective view showing an example of the appearance of the surgical practice kit of the present invention, and FIGS. 2 (a) to 2 (c) are a plan view, a front view and a side view thereof. FIG. 3A is an enlarged view of the cross-section of the string-like body and the retainer for explaining the state where the retainer is attached to the string-like body, and FIG. 3 (c) corresponds to a diagram showing a state in which the height and inclination of the mounting table in FIG. 2 (b) are changed.
4A is a plan view showing a state in which the surgical practice kit shown in FIGS. 1 to 3 is folded, and FIG. 4B is a cross-sectional view taken along line AA in FIG. 4A. FIG. And FIG. 5 is a figure for demonstrating the usage method of the surgery practice kit of this invention.

As shown in FIGS. 1 and 2, the surgical practice kit 1a according to the present invention includes a top plate 2, side plates 3a, 3a and reinforcing plates 3b, 3b formed of a transparent member such as synthetic resin or glass, and a top plate. Hinges 4 a and 4 b attached to the lower surface of the disk 2, a disk-shaped mounting table 5, four string-shaped bodies 6 each fixed to the top plate 2 and the mounting table 5, and both ends of the string-shaped body 6 The stopper 7 attached to the is provided.
The top plate 2, the side plate 3a, and the reinforcing plate 3b are all rectangular in plan view, but the width in the direction orthogonal to the side connected to the top plate 2 is greater for the reinforcing plate 3b than for the side plate 3a. Further, the reinforcing plate 3b is formed in an elongated rectangular shape as compared with the side plate 3a.

One end of the pair of side plates 3a, 3a is connected to one side of the top plate 2 via a pair of hinges 4a, 4a that can be rotated in a range of 0 ° to 90 °, respectively, near one pair of opposite sides. At the same time, one end of the pair of reinforcing plates 3b, 3b is connected to the vicinity of the other pair of opposite sides via two pairs of hinges 4b, 4b that can be rotated in the range of 90 ° to 180 °. However, the hinges 4a and 4a are installed so that each axis is along one set of opposite sides, and the hinges 4b and 4b are installed so that each axis is along another set of opposite sides.
In this embodiment, two pairs of hinges 4a and 4b are provided. However, if they are somewhat longer than the length of each side of the top plate 2, a pair of hinges 4a and 4b is used instead of two pairs. It is good also as a structure provided one by one.

  That is, one end of the side plates 3a and 3a is rotatably connected to the top plate 2, and when the angle of the hinges 4a and 4a is 0 °, the side plates 3a and 3a are parallel to the top plate 2 as shown in FIG. ) As shown in FIG. When the angles of the hinges 4a and 4a are 90 °, the side plates 3a and 3a are orthogonal to the top plate 2 and the top plate 2 is passed over them. In this case, the side plates 3a, 3a function as legs that support the top plate 2 horizontally.

The reinforcing plates 3b and 3b are also connected to the top plate 2 so that one end thereof is rotatable, and are orthogonal to the top plate 2 when the angles of the hinges 4b and 4b are 90 °. At this time, since both end surfaces of the reinforcing plates 3b and 3b are in contact with the inner surfaces of the side plates 3a and 3a, the side plates 3a and 3a cannot be rotated and the state orthogonal to the top plate 2 is maintained.
That is, the reinforcing plates 3b and 3b function as stoppers that prevent the side plates 3a and 3a from rotating when they are orthogonal to the top plate 2. In this case, since there is no possibility that the side plates 3a, 3a will rotate freely so as to fall inward, the surgical practice kit 1a can be used safely in a stable state.

On the other hand, the reinforcing plates 3b and 3b are parallel to the top plate 2 as shown in FIG. 4A when the angle of the hinges 4b and 4b is 180 °. At this time, the reinforcing plates 3b and 3b do not contact the inner surfaces of the side plates 3a and 3a at both end surfaces, and the function as the above-described stopper that prevents the side plates 3a and 3a from falling into the inner side is not exhibited.
That is, the surgical practice kit 1a has an effect that the side plates 3a and 3a can be easily folded inward by rotating the reinforcing plates 3b and 3b to a state parallel to the top plate 2.

The top plate 2 is provided with four through-holes at substantially equal intervals along the circumferential direction around a circular opening 2a provided substantially at the center, and each through-hole has a string 6 The upper part of each is inserted. Also, below the top plate 2, a mounting table 5 in which four through holes are provided in the vicinity of the peripheral edge at substantially equal intervals along the circumferential direction is arranged coaxially with the opening 2a. The lower part of the string-like body 6 is inserted in each through hole. The string-like body 6 has a stopper 7 attached to portions protruding from the through holes of the top plate 2 and the mounting table 5.
That is, the string-like body 6 is connected to the top plate 2 and the mounting table 5 so that both ends thereof are not easily removed from the through hole. The body 6 is suspended so as to be swingable with respect to the top plate 2.

  The retainer 7 is a substantially spherical elastic body formed of silicon, rubber or the like, and as shown in FIG. 3A, an insertion hole 7a of the string-like body 6 is provided so as to pass through the center thereof. Yes. The insertion hole 7a is formed in such a size that the string-like body 6 can be anchored at an arbitrary position by the elastic force of the elastic body and the string-like body 6 can be slid against the elastic force. ing. Further, the string-like body 6 is formed so that the outer diameters of both end portions are larger than the outer diameters of the other portions so that the stopper 7 is not dropped off.

  In the surgical practice kit 1a having such a structure, when the length of the string-like body 6 between the top board 2 and the mounting table 5 is changed, as shown in FIGS. 3 (b) and 3 (c), the mounting table 5 and the height of the mounting table 5 with respect to the upper surface of the desk on which the surgical practice kit 1a is installed easily change. When the retainer 7 is slid and moored at a predetermined position of the string-like body 6, the length of the string-like body 6 between the top plate 2 and the mounting table 5 is maintained in the changed state. The

  That is, according to the surgical practice kit 1a, since the inclination and height of the mounting table 5 on which the organ model is placed on the upper surface can be easily adjusted, the organ model is supported in a predetermined posture. It is possible to create a situation that is most suitable for learning. In addition, the surgical practice kit 1a can easily change the length of the string-like body 6 between the top plate 2 and the mounting table 5 by simply sliding the stopper 7 without any special operation. Since the state is maintained, the operability is excellent.

  Further, in the surgical practice kit 1a, the top plate 2, the side plate 3a, the reinforcing plate 3b, and the mounting table 5 are formed of transparent members, and an organ model is placed on the upper surface of the mounting table 5 to practice surgery. This can be easily confirmed visually from the outside. That is, according to the surgery practice kit 1a, the surgeon can practice while confirming the state of the surgery, so that necessary techniques can be efficiently learned.

  As shown in FIG. 3C, when the camera 11 is installed below the mounting table 5, the state in which the organ model is sutured or the like can be seen from an angle that cannot be visually observed during actual surgery. You can shoot. At that time, the surgical practice kit 1a can finely adjust the posture of the organ model by swinging the mounting table 5, so that the unique effect of taking an image from an optimum angle is exhibited.

When the surgical practice kit 1a is not used, when the pair of side plates 3a, 3a and the reinforcing plates 3b, 3b are folded inward as shown in FIG. This makes it very easy to carry and store.
In addition, as shown in FIG. 5, the surgeon practicing surgery using the surgical practice kit 1 a puts his hand into the opening 2 a from above the top plate 2 and places it on the upper surface of the mounting table 5. In this case, the movable range of the hand is restricted by the opening 2 a of the top 2. Furthermore, since the mounting table 5 that supports the organ model 12 is suspended from the top plate 2 via the string-like body 6, the organ model 12 is in a state that it is very easy to swing together with the mounting table 5. .
As described above, according to the surgical practice kit 1a, it is possible to faithfully reproduce the situation at the time of actual surgery that "an organ supported in an unstable state must be handled in a narrow space". . Therefore, an operator who performs an operation practice using the operation practice kit 1a can efficiently acquire a necessary technique.

The structure, operation, and effect of Example 2 of the surgical practice kit according to the embodiment of the present invention will be specifically described with reference to FIG.
6A is an external perspective view of the surgical practice kit of this embodiment, and FIGS. 6B to 6D are external views of the substrate, the mounting plate, and the elastic plate shown in FIG. 6A, respectively. It is a perspective view. In addition, about the component shown in FIG. 1 thru | or FIG. 5, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIGS. 6 (a) to 6 (d), the surgical practice kit 1b of the present invention is the same as the surgical practice kit 1a of the first embodiment. A mounting plate 9 and an elastic plate 10 provided with notches 9a and 10a, respectively, which can be inserted into the substrate 8 and the string-like body 6 and can be locked to the stopper 7; The attachment plate 9 is installed on the top surface of the top plate 2 with the string-like body 6 inserted into the notch 9a, and the elastic plate 10 with the string-like body 6 inserted into the notch 10a. Is installed between the top plate 2 and the mounting plate 9. The elastic plate 10 is formed of an elastic member such as rubber or elastomer, a gel-like member, or the like.

In the surgical practice kit 1b having such a structure, the side plates 3a and 3a, whose lower ends are respectively inserted into the recesses 8a and 8a, are held unrotatable by the substrate 8, so that the side plates 3a and 3a rotate freely. The use state is further stabilized and the safety is further improved.
Further, when the surgeon applies a force to the organ model placed on the upper surface of the placing table 5, the elastic plate 10 is compressed by the retainer 7 through the mounting plate 9, and the organ model is appropriately adjusted accordingly. Will sink into. That is, according to the surgical practice kit 1b, the degree of subsidence changes depending on the level of force applied by the surgeon to the organ model, so that the organ to be operated can be placed on other elastic organs. It is possible to faithfully reproduce the actual situation at the time of surgery.

  The surgical practice kit of the present invention is not limited to the structure shown in the present embodiment. For example, a structure in which at least a part of the string-like body 6 is formed of an elastic material such as a spring or rubber can be used. In this case, the main effect is that the string-like body 6 expands and the organ model 12 sinks appropriately in accordance with the level of the operator's force applied to the organ model placed on the upper surface of the placing table 5. This is demonstrated in the same manner as in the embodiment.

  However, as shown in this embodiment, when the elastic plate 10 is installed, the organ model is more suitable for the degree of force applied by the operator than when the string-like body 6 is formed of an elastic material. There is a possibility that subtle differences in the elasticity of different organs can be reproduced more faithfully depending on the type of organ, the age of the patient, or the progress of the medical condition.
