Embodiment 1

[0030] Such as Figure 1-3As shown, the abdominal wall support device for pneumoperitoneum laparoscopic surgery includes a rod-shaped main body 1 that is matched with the poking hole of the laparoscope. 1 is provided with at least one chute 11, the chute 11 is arranged radially along the rod-shaped main body 1, the support mechanism 2 is arranged in the chute 11, and the support mechanism 2 includes telescopic tubes detachably connected to each other 21 and a slider 22, the slider 22 is made of silica gel material, the telescopic tube 21 is detachably connected with an air supply device 3, and the gas supply device 3 fills gas into the telescopic tube 21 to control The slider 22 slides into and / or out of the chute 11. When the slider 22 moves into the chute 11, the outer surface of the slider 222 is coplanar with the outer surface of the rod-shaped main body 1. When the block 22 is away from the rod-shaped main body 1, the supporting mechanism 2 supports the abdominal cavity ...

Embodiment 2

[0037] like Figure 1-3 As shown, the abdominal wall support device for pneumoperitoneum-free laparoscopic surgery of this embodiment has the same structure as that of Embodiment 1, the difference is that a retraction mechanism 4 is arranged inside the telescopic tube 21, and the retraction mechanism 4 is connected with the slider 22 is detachably connected, and the retraction mechanism 4 exerts a force on the slider 22 toward the rod-shaped main body 1 .

[0038] In the abdominal wall support device for pneumoperitoneum-free laparoscopic surgery in this embodiment, the contraction mechanism 4 is arranged in the telescopic tube 21, on the one hand, the strength of the telescopic tube 21 is strengthened, so that the telescopic tube 21 is not easy to bend, which is conducive to maintaining the stability of the operation space. On the other hand, since the shrinking mechanism 4 exerts a pulling force on the slider 22, when the air supply device 3 stops supplying air, the pulling ...

Embodiment 3

[0041] like Figure 1-3 As shown, the abdominal wall support device for pneumoperitoneum-free laparoscopic surgery of this embodiment has the same structure as that of Embodiment 1, the difference is that a magnetic piece 5 is embedded in the slider 22, and a rod-shaped body 1 is also provided with a At least one positioning mechanism 6, the positioning mechanism 6 is located outside the abdominal cavity, the positioning mechanism 6 moves with the magnetic part 5, and the positioning mechanism 6 includes at least one metal block 61, between the metal block 61 and the rod-shaped main body 1 Connected by the connecting piece 62, the metal block 61 moves outside the abdominal cavity with the magnetic piece 5.

[0042] In the abdominal wall support device for pneumoperitoneum-free laparoscopic surgery of this embodiment, the magnetic piece 6 is embedded in the slider 22, and a metal block 61 is set outside the abdominal cavity as a positioning mechanism 6 to move with the magnetic...

Abstract

The invention relates to the field of medical devices, and in particular to an abdominal wall supporting device for a gasless laparoscopic surgery. The device comprises a rod-shaped body that cooperates with a cavity mirror puncture, wherein the rod-shaped body is provided with a through hole that cooperates with a laparoscope, the rod-shaped body is provided with at least one supporting mechanism, and the supporting mechanism comprises a telescopic tube and a slider which are detachably connected to each other, the slider is made of silicone material, and the telescopic tube is detachably connected with a gas supply device, the gas supply device controls the amount of gas in the telescopic tube, changes the distance between the slider and the rod-shaped body, and the telescopic tube is ina contracted state when the rod-shaped body is placed in the abdominal cavity in order to prevent the supporting mechanism from causing damage to the cavity mirror puncture, during the extension of the telescopic tube, the slider made of silicone material does not cause damage to the organ, at the same time, the gas supply device is used to control the moving speed of the slider, so as to avoid the crushing injury caused by the slider moving too fast, the abdominal wall and the internal organs can separate safely to form a surgical space for laparoscopic surgery in the abdominal cavity.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an abdominal wall support device for pneumoperitoneum-free laparoscopic surgery. Background technique [0002] Traditional laparoscopic surgery usually needs to introduce carbon dioxide into the abdominal cavity, separate the abdominal wall and intracavitary organs, form a carbon dioxide pneumoperitoneum space that is convenient for manual operation, and perform the operation under pneumoperitoneum. However, because carbon dioxide can be absorbed through the peritoneum, excessive The high carbon dioxide can easily cause hypercapnia and acidosis, especially for elderly patients, after establishing artificial carbon dioxide pneumoperitoneum for laparoscopic surgery, abnormal changes in heart rate and respiration are prone to occur, and because of the pneumoperitoneum process, the venous return of the patient's lower extremities is significantly reduced, The central venous pressure ...
