Description

The present invention relates to a training device for laparoscopic surgery.

Among this type of laparoscopic surgery training equipment, examples of kits that are easy to use and allow for practice include the commercially available "personal dry box" and the laparoscopic surgery training device described in JP 2019-207304 A. Hereinafter, these will be referred to as training kits.

These inventions are thought to be based on the same idea as the present invention. For example, in Non-Patent Document (1), a simple case, thought to be made of resin, is equipped with a human body model, and a camera and multiple surgical instruments attached to the side panel are used for, for example, surgical training or remodeling. Furthermore, Patent Document (1) also states, for example, in [0004], that "Since the abdominal wall is simulated with a flexible material that can be pierced with a needle-shaped member or cut with a blade, it is possible to create an environment that is closer to an actual surgical operation than before, which has the excellent effect of enabling better surgical training."

A preferred embodiment of the present invention is described below.

1 to 3, the training equipment has an outer shell 1 of a case made of a plate material formed into a cube shape using an outer shell material made of cardboard , thick paper , wood, or resin as necessary. This outer shell 1 is foldable and can form a storage space H.

As can be seen, for example, in the unfolded state shown in Fig. 1, the outer shell 1 has a first plate 3 with a first rising piece 3a attached to the right side and a second plate 5 with a second rising piece 5a attached to the left side in the figure, with a rectangular base plate 2 with first to fourth rising pieces 3a, 5a, 6a, and 7a attached to it, as a base point, in four directions, a front plate 6 with a fourth rising piece 7a located in front of the first plate 3 and the second plate 5 ( upper side in Fig. 1 ) , and a support plate 7 with a third rising piece 6a located behind the first plate 3 and the second plate 5 ( near side in Fig. 1 ) . Between the first plate 3 and the front plate 6, and between the second plate 5 and the front plate 6, a pair of openings, each of which has an obtuse angle in a plan view, are symmetrically located.

With reference to FIG. 1, in this invention, the direction X will be described as the front (the position where the front plate 6 is provided) and the direction Y will be described as the rear (the position where the support plate 7 is provided). In addition, the direction Z1 will be described as the right (the position where the first plate 3 is provided) and the direction Z2 will be described as the left (the position where the second plate 5 is provided).

The base plate 2, the first and second plates 3, 5, the front plate 6, and the support plate 7 form the outer shell 1 and the cube shown in Fig. 3. The front plate 6 is opaque, with the intention of enabling the trainee to quickly and reliably achieve the results of the training. In other words, the target placed on the base plate 2 located behind the front plate 6 at the rear Y is prevented from being seen by the trainee with the naked eye. In this example, the first and second plates 3, 5 can conceal both sides (one direction is also possible), which is effective in preventing, for example, the occurrence of obstacles such as light and reflection, but is not limited thereto (the same applies to the other plates , although not explicitly stated).

The front X of the first plate 3 is an upright edge 3-1, and the rear Y is a recessed edge 3-2. This upright edge 3-1 is formed with a first gusset piece 3d having a hook-shaped third notch 3b through which the third hole 3c can be formed. In principle, this first gusset piece 3d is formed to bulge out towards the same surface as the second gusset piece 5d (see Figure 2). When this first gusset piece 3d is folded onto the surface of the first plate 3, the third notch 3b rises, and the third hole 3c is formed along the third notch 3b (see Figure 6). In addition, a first edge 3e that rises vertically is provided at the upper end of the first rising piece 3a that rises from the base plate 2, and a first notch 3f and a first hole 3g are formed adjacent to this first edge 3e. When the first plate 3 is folded, a first insertion piece 8 (described later) that bulges out to the right Z1 of the front plate 6 is inserted and supported in this first hole 3g (see Figures 2 and 3).

The second plate 5 has an upright edge 5-1 at the front X and a recessed edge 5-2 at the rear Y, and this upright edge 5-1 is formed with a second gusset piece 5d having a hook-shaped fourth notch 5b through which the fourth hole 5c can be formed. In principle, this second gusset piece 5d is formed to bulge toward the same surface as the first gusset piece 3d (see Figure 2). When this second gusset piece 5d is folded onto the surface of the second plate 5, the fourth notch 5b rises, and the fourth hole 5c is formed along the fourth notch 5b (see Figure 6). In addition, a second edge 5e that rises vertically is provided at the upper end of the second rising piece 5a that rises from the base plate 2, and a second notch 5f and a second hole 5g are formed adjacent to this second edge 5e. When the second plate 5 is folded (superimposed on the base plate 2), a second insertion piece 9 (described later) that bulges out to the left Z2 of the front plate 6 is inserted and supported in this second hole 5g (see Figures 2 and 3).

As mentioned above, the first insertion piece 8 is formed on the right side Z1 edge of the front panel 6, and the second insertion piece 9 is formed on the left side Z2 edge of the front panel 6.

A support plate 7 is provided on the third rising piece 6a at the rear Y of the base plate 2, and a key-shaped fifth notch 10 is formed at the connection between this support plate 7 and the third rising piece 6a. When the support plate 7 is folded parallel to the base plate 2, this fifth notch 10 forms a fifth hole 11 (see Figure 2). The third insertion piece 12, which is bulged out at the front X of the front plate 6, is inserted and supported in this fifth hole 11 when the front plate 6 is folded (see Figure 3).

Furthermore, a fold line 15 is formed at each joint of each plate material.

In Fig. 1, Fig. 3, Fig. 6, etc., a combination of the first gusset piece 3d, the third notch 3b and the third hole 3c provided therein, and an example of its use will be described as follows: As shown in Fig. 6, the first gusset piece 3d is bent in the plane direction to the left Z2, and rises from the third notch 3b, leaving a notch remaining piece 3h, and the third hole 3c is formed, and the first insertion piece 8 is inserted into this third hole 3c, and the front plate 6 rises (see Fig. 7, etc.). Also, the combination of the second gusset piece 5d, the fourth notch 5b and the fourth hole 5c provided therein, and an example of its use are the same as the above-mentioned examples, so the description will be omitted. Also, an example of the use of the second plate 5 is similar to the above-mentioned example of the use of the first plate 3.

1, 3, etc., the relationship between the first notch 3f and the first hole 3g formed in the first plate 3 is explained as follows: by providing the first notch 3f, the first end edge 3e of the first rising piece 3a is formed in an upright state, and the first hole 3g is structured so that the first end edge 3e fits in when the first plate 3 is folded toward the base plate 2. Also, as shown in Figs. 1, 2, and 5, the explanation of the relationship between the second notch 5f and the second hole 5g formed in the second plate 5 and the use example are the same as the above-mentioned example, and the explanation will be omitted. Also, the cutout remaining piece 5h of the second gusset piece 5d of the second plate, which corresponds to the cutout remaining piece 3h of the first gusset piece 3d shown in the first plate 3, is shown in Fig. 2 and is also shown in Figs. 5 and 6. Also, other than the second plate 5, it is similar to the above-mentioned first plate 3.

1, 2, 5, etc., the relationship between the support plate 7, the third rising piece 6a, the fifth notch 10, and the fifth hole 11 will be described. The fifth notch 10 and the fifth hole 11 are provided at the joint between the third rising piece 6a and the support plate 7, and the fifth hole 11 is formed when the support plate 7 is folded onto the base plate 2, and the fifth notch 10 is located inside the third rising piece 6a (see FIG. 2). The third insertion piece 12 is inserted and supported in the fifth hole 11 when the front plate 6 is folded onto the upper side of the base plate 2 (superimposed on the base plate 2). In this state and when the first plate 3 and the second plate 5 are folded, the outer shell 1 is folded into a thin plate shape as shown in FIG. 3. As a result, a storage space H surrounded by the base plate 2, the first and second plates 3 and 5, and the front plate 6 is formed . The storage space H contains the video device 40, the camera 42, the cord 43, etc. When carrying the device, it is preferable to store it in a hard container such as a plastic bag or sack.

Next, an example of a method of using the device as a training device for laparoscopic surgery shown in Figures 7 and 8 will be described. The first plate 3 and the second plate 5 are raised, and the third notch 3b and the fourth notch 5b are bent at approximately right angles to the surface direction of the first plate 3 and the second plate 5. This bending forms the third hole 3c and the fourth hole 5c. The first insertion piece 8 and the fourth insertion piece 9 of the front plate 6 are inserted (inserted) toward the third hole 3c and the fourth hole 5c while being bent at approximately right angles. When the first and second plates 3 and 5 are raised and the front plate 6 is raised , a storage space H that is U-shaped in plan view and is surrounded by these plates and the base plate 2 is formed. At the same time, the base plate 2 of the storage space H is hidden from the outside , and the data of the installed human body model and the operation status are displayed as images on the screen of the video device 40 that is housed in the storage space H or arranged behind it . In principle, the support plate 7 can be raised up against the upper surface of the base plate 2 or laid down ( folded) on the upper surface. Based on this video, the patient uses at least two surgical instruments 41 to simulate surgery and learn the techniques and precautions. Representative examples of the surgical instruments 41 include surgical forceps, scissors, and a needle holder, but it goes without saying that any other instruments, devices, etc. used in laparoscopic surgery may also be used . The video device 40 in the figure is a computer, tablet, or other device.

In the figure, B indicates a simulated abdominal cavity. Holes 44 are holes into which one or more surgical instruments 41 are inserted, and packing 45 that can be used as a guard, guide, slide, etc. is attached to these holes 44. Numeral 46 indicates an anti-slip material, and multiple pieces are provided on the back surface of the base plate 2.

After use, it can be folded freely, for example, simply by reversing the assembly steps described above. For example, see the methods shown in Figures 2 and 5.

9-1 to 9-7 are examples of assembly of the outer shell 1. In FIG. 9-1, for example, the front plate 6 provided at the front X in the longitudinal direction Q is foldable, and the front plate 6 can be raised by a support part 100 provided at the rear Y. However, the structure is such that the storage space H can be formed. The front plate 6 does not necessarily have to be configured to completely close the storage space H. In FIG. 9-2 and FIG. 9-3, the front plate 6 is raised using the legs 101 ( rods, armrests, etc. ) , and the rest is similar to FIG. 9-1. The legs 101 are separate from the outer shell 1 (components of the outer shell 1, such as the front plate 6, the base plate 2, the first plate 3, etc.), and examples of the legs include rods, paper, rulers, various rods, wood, etc. The same applies below . Also, in FIG. 9-4, the front plate 6 is raised using the support piece 102, and the rest conforms to FIG. 9-1. In FIG. 9-5, the front plate 6 is not limited as long as it is a folding type or a rolling type and forms the storage space H. The rest conforms to FIG. 9-1. In FIG. 9-6, the hinge 6b of the front plate 6 is movable by a pin 51 at the bottom (composed of the base plate 2 and the first to fourth rising pieces 3a to 7a, etc.) and can be fixed as necessary, and the bottom is closed by the front plate 6 to form the storage space H. In FIG. 9-7, the front plate 6 (lid portion) is fitted (covered) on the bottom, like a housing or case. In this example, the lid portion is raised to the bottom and used. The rise is achieved by using, for example, the legs 101. The other structures conform to the above-mentioned assembly examples.

The present invention is not limited to the embodiments, and various modifications are possible within the scope of each claim. In other words, embodiments obtained by combining technical means that are appropriately modified within the scope of each claim are also included in the technical scope of the present invention.
