Problems solved by technology

[0005] However, if it is used as a simulator for training suturing techniques such as the bladder and urethral tube, it is difficult to judge whether the pelvic structure, urethral tube, or bladder are reproduced realistically. Problems of labor required for position adjustment when imitating the structure of the insertion body of human tissue

Embodiment 1

[0066] refer to Figure 1 to Figure 12 , the abdominal cavity simulator described in Example 1 will be described.

[0067] Such as figure 1 The abdominal cavity simulator shown has a shell 2 that simulates the abdominal cavity and pelvis needed to practice laparoscopic surgical skills, figure 2 Shown is the bladder model 10 and the suturing training device of the urethral tube 4 . Shell 2 that simulates the abdominal cavity and pelvis, the lower field of the abdominal cavity is simulated, figure 2 Shown is the opening on the diaphragm side of the abdominal space.

[0068] Such as image 3 As shown, the shell cover 3 can be removed from the abdominal cavity simulator 1 . Shell cover 3 in Figure 4 As shown, a plurality of through-holes (five through-holes in the figure) are provided, and the insertion holes 5 are provided in these through-holes. The insertion hole 5 has an insertion opening 6 through which forceps or surgical instruments can be inserted into the abdomi...

Embodiment 2

[0077] Regarding the shell cover of the abdominal cavity simulator involved in embodiment 2, refer to Figure 13 ~ Figure 15 Be explained.

[0078] The shell cover of the abdominal cavity simulator involved in embodiment 2 is different from the shell cover of the abdominal cavity simulator involved in embodiment 1, such as Figure 13 and Figure 14 As shown, the size of the insertion hole portion 7 becomes smaller, and the number of arrangement becomes larger. The socket port 8 is configured on the shell cover as a whole, such as Figure 15 As shown, the degree of freedom of the insertion position of the pliers 31 can be increased.

Embodiment 3

[0080] Regarding the abdominal cavity simulator involved in embodiment 3, refer to Figure 16 ~ Figure 20 Be explained. Figure 17 (1) is a front view of the abdominal cavity simulator, (2) is a rear view, (3) is a left side view, and (4) is a right side view. The abdominal cavity simulator involved in embodiment 3, such as Figure 16 and Figure 17 As shown, the shape of the shell approximates the shape of the abdomen to the pelvis of the human body. In addition, the casing itself is made of a light-transmitting material, so that the inner space of the casing, that is, the abdominal cavity space, can be observed. The casing of the abdominal cavity simulator 40 is composed of a casing part of the abdomen 41 , a casing part of the pelvic part 42 , a casing part of the back 43 , and a cover part 44 which will be described later. A plurality of insertion openings 45 are formed on the abdomen 41 . Forceps or surgical instruments can be inserted into the abdominal space throug...

Abstract

A simulator for training laparoscopic surgery skills, providing an abdominal cavity simulator that can be easily adjusted in position when exchanging a bio-textured organ model for repeated training. The abdominal cavity simulator of the present invention is composed of a pelvis, a back, and an abdomen shell, a biologically textured organ model, and a model holding part. The shell at least consists of a pelvic part that simulates the shape of a human body, a back with left and right transverse abdomens, and simulates the abdominal cavity space and the pelvis. In addition, the model holding part is a holding part arranged on the back or the pelvis, and fixes, places or holds the biologically textured organ model in the abdominal space. In addition, when performing the suturing training of the bladder model 10 and the urethral tube 4, a belt-shaped member 11 abutting against the inner wall of the shell 2 of the pelvic portion is set on the bladder model 10, and the bladder model 10 is separated from the urethral tube 4 through the belt-shaped member. The abdominal space was removed and placed.

Description

technical field [0001] The invention relates to an abdominal cavity simulator used for training or learning laparoscopic operation skills. Background technique [0002] In recent years, Intuitive Surgical, Inc. of the United States has developed a medical robot DA VINCH (registered trademark) for master-slave endoscopic surgery. In order to improve the level of operation of the medical robot, devices are known which simulate the abdominal and pelvic cavities. Generally, the housing of such a device is provided with a socket for inserting the forceps or instruments of the above-mentioned medical robot, and surgical skills training is performed on abdominal internal organs such as the bladder accommodated in the housing. [0003] Known techniques such as incision and skin suturing in medical clinics are known. By receiving perceptual training training close to reality, even if clinical experience is insufficient, it is possible to acquire a highly technical percutaneous surge...
