[0027] One embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0028] (Overall structure) Figure 1 is an overall view showing the simulator device 1 for the surgical training device of this embodiment.

[0029] This simulator device 1 comprises a base member 2 and a cover member 3 detachably attached to the base member 2. The cover member 3 is detachably attached to the end edges 2a and 2b of the base member 2, respectively, with its middle section in the longitudinal direction bent. The cavity 5 formed between the cover member 3 and the base member 2 constitutes a simulated thoracic cavity, and a simulated organ model is placed on the base member 2 within this cavity 5, as will be described later. In addition, the middle section in the longitudinal direction of the cover member 3 is provided with multiple through-holes 7 for the trainee to insert a simulated surgical instrument such as an endoscope into the simulated thoracic cavity (cavity 5).

[0030] Furthermore, a foldable frame member 8 is provided at the end of the base member 2 in a direction perpendicular to the longitudinal direction of the base member 2, in order to maintain the simulated abdominal and thoracic cavity shape.

[0031] Furthermore, the LED lights indicated by reference numeral 9 in the figure are a pair of LED lights that are supported at both ends by the frame member 8 and extend in the width direction of the cover member 3. By using these LED lights 9, the simulated organ model installed in the cavity 5 can be illuminated.

[0032] The following provides a more detailed explanation of each component, particularly the configuration of the base member 2 (frame member 8) and the cover member 3.

[0033] (Base component) Figure 2 is a perspective view showing the base member 2. This base member 2 is a rectangular flat plate in shape, and three snap button receiving parts 4a and 4b for attaching the ends 3a and 3b of the cover member 3 are attached to both end edges 2a and 2b in the width direction of the base member 2 at predetermined intervals along these side edges.

[0034] As mentioned above, foldable frame members 8 are attached to both ends of this base member 2. This frame member 8 has a peach shape. That is, it has a peach-shaped apex 8a, two side parts 8b provided symmetrically on either side of the apex 8a, and a base part 8c that connects these two side parts 8b.

[0035] The base portion 8c of the frame member 8 is attached to the base member 2 by a hinge component 10, indicated by reference numeral 10 in Figure 2. One end of the movable hinge piece of this hinge component 10 is fixed to the surface of the base member 2, and the other end is fixed to the base portion 8c of the frame member 8.

[0036] Furthermore, the hinge component 10 is configured to ensure a predetermined gap 11 between the frame member 8 and the base member 2, whether in the closed state (Figure 3) or the open state (Figure 2), allowing the ends 3a and 3b of the cover member 3 to be inserted. Figures 4 and 5 are side views showing this configuration. This configuration prevents the cover member 3 and the frame member 8 from interfering with each other and causing damage.

[0037] (Cover component) Figure 6 is a plan view showing the cover member 3. This cover member 3 is made of a flexible plastic material such as polypropylene or polyethylene terephthalate, and its length dimension a is formed by the outer circumference length of both sides 8b of the peach-shaped frame member 8 plus the lengths of both ends 3a and 3b. The through hole 7 is located in the middle of its length, and the convex side snap button parts 4b are installed at both ends 3a and 3b.

[0038] (assembly) Next, we will explain how to assemble this simulator device 1.

[0039] First, the base member 2 is placed on a flat surface, and the frame member 8 is raised from the state shown in Figure 3 to the state shown in Figure 2. Next, the LED lighting 9 is attached to the frame member 8 as indicated by arrow A in Figure 7.

[0040] Next, the middle portion of the cover member 3 in the longitudinal direction is bent upward, and both ends 3a and 3b are held in a folded state. In this state, it is placed over the frame member 8 as shown by arrow B in the figure, and then both ends 3a and 3b are inserted into the gap 11 between the frame member 8 and the base member 2 as shown by arrow C in the figure, aligning the receiving part 4a and the convex part 4b of the snap button. Then, the six snap button receiving parts 4a and convex parts 4b are fitted together and fixed so that they can be attached and detached. With this, the simulator device 1 for the surgical training device is completed as shown in Figures 1 and 8.

[0041] (How to use) When using this simulator device 1, for example, as shown in Figure 8, a simulated organ 15 for surgical training is placed approximately in the center of the base member 2.

[0042] This simulator device 1 is used, for example, for training in securing a field of view during endoscopic procedures.

[0043] In terms of usage, a port 16 is attached to a through-hole 7 (see perspective view and top view) provided in the cover member 3, and a training endoscope 17 is inserted through this port 16 to secure a field of view, thereby enabling training.

[0044] Furthermore, for more realistic training, as shown in Figure 9, the simulated skin member 19 is placed on the cover member 3, and an incision is made at a position 19a corresponding to the through-hole 7 into which the endoscope 17 is inserted. Then, the port 16 is inserted through this incision 19a and attached to the cover member 3. Additionally, the detachable tilt stand 18 attached to the device 1 is used to hold the entire simulator device 1 at a desired angle. Preferably, as shown in Figure 9, the tilt stand 18 has a saliva portion 18a that holds one end of the base member, and this saliva portion 18a is fixed to the base member 2 or hinge member by a fastener such as a screw 18b.

[0045] (Foldable) This simulator device 1 can be easily disassembled by removing the snap buttons 4a and 4b and detaching the cover member 3 from the frame member 8. Then, by returning the cover member 3 to its original flush state and folding the frame member 8 that was raised on the base member 2, the base member 2 and the cover member 3 can be returned to a flat state. After that, the two can be stacked and stored in a case.

[0046] This makes it possible to obtain a simulator device 1 that can be easily assembled into a flat shape for transport and into a three-dimensional shape for assembly.

[0047] Furthermore, this invention is not limited to the above-described embodiment, and can be modified in various ways without altering the essence of the invention.

[0048] For example, the cover member 3 in the above embodiment uses a flexible plastic material such as polypropylene or polyethylene terephthalate, but as shown in Figure 1, any material other than the above may be used as long as it has sufficient elasticity to form a cavity 5 between the cover member 3 and the base member 2 by bending the middle portion in the longitudinal direction, thereby forming a simulated thoracic cavity.

[0049] Furthermore, although the cover member 3 of the above embodiment is provided with a through-hole 7 for the trainee to insert their hand or instrument into the thoracic cavity, as shown in Figures 3 and 9, the size and shape of the through-hole 7 may be changed to match the size and position of the surgical training target holding device installed on the base member 2 within the hollow portion 5.

[0050] Furthermore, the fastener member 4 attached to the base member 2 and the cover member 3 is not limited to a snap button 4, but can be selected from a variety of materials, including the material used in the above embodiment, such as hook-and-loop fasteners, decorative screws, and double-sided sheets, as long as it satisfies the condition of being detachable.

[0051] Furthermore, although the cover member in the above embodiment was fixed on the base member 2, it is not limited to this and may also be fixed to the lower surface of the base member 2. For example, the edges 3a and 3b of the cover member 3 may be passed under the base member 2 and fastened to screw holes provided in the base 11 with decorative screws of about 4 mm in diameter to secure it.
