Pneumoperitoneum-free peritoneoscope abdominal wall suspension device

Abstract

A pneumoperitoneum-free peritoneoscope abdominal wall suspension device comprises a hollow incision protecting sleeve with a suspension function and a splint, wherein the incision protecting sleeve with the suspension function is formed by a lifting part, a ring sleeve and a fixing part in an integrated mode from bottom to top, the incision protecting sleeve and the splint are fixedly connected through the fixing part, the incision protecting sleeve with the suspension function is made of soft material, and the thickness of the lifting part is larger than that of the ring sleeve. Preferably, the device further comprises a hollow annular supporting ring installed on the inner wall of the ring sleeve in a matched mode, the shape of the supporting ring is consistent with that of the incision protecting sleeve, and the hardness of the supporting ring is larger than that of the incision protecting sleeve; more preferably, the thickness of the portion, close to the center area, of the lifting part of the incision protecting sleeve with the suspension function is smaller than that of the edge area of the lifting part; the abdominal wall below an operation incision can be supported by using the device, not only are unnecessary injuries to the abdominal wall avoided, but also an operation view is good, meanwhile, the pneumoperitoneum-free peritoneoscope abdominal wall suspension device is simple in structure and convenient to operate, pneumoperitoneum-free peritoneoscope surgery is completed by using conventional laparoscopic surgery instruments, and untoward effects caused by pneumoperitoneum are avoided.

Description

technical field [0001] The invention relates to the field of laparoscopic surgical instruments, in particular to a gas-free laparoscopic abdominal wall suspension device. Background technique [0002] With the gradual improvement of medical technology, more and more diseases can achieve the best curative effect through laparoscopic minimally invasive surgery. Laparoscopic technology can provide the space required for surgical operations by making CO2 artificial pneumoperitoneum, but because CO2 pneumoperitoneum can cause complications such as hypercapnia, air embolism, and blood stasis, this technique is not suitable for tissues and organs that are mature. The application in children, pregnant women and elderly patients with underlying diseases is limited. Pneumoperitoneum-free laparoscopy is an important technology in the field of minimally invasive surgery. It uses external mechanical tension to provide operating space for surgery, does not rely on artificial pneumoperito...

AI Technical Summary

Problems solved by technology

However, this technology has the following disadvantages: the device needs to be vertically inserted into the abdominal cavity to a certain depth in the disturbed state before the support arm can be opened in an umbrella shape by pulling the rope, and the space in the abdominal cavity is limited. Blindly inserting the device and further opening it to the surroundings may cause damage to the intestinal tube; on the other hand, the device is moved from the distracted state to the extended state by the movement of the pull rope and prevents slippage. , due to minimally invasive reasons, the design of the device requires a small diameter and height, which results in a small displacement of the pulling rope sliding over the fulcrum during the process from the device being folded to the device being opened, and it is easy to be caused by excessive support of the abdominal wall. Due to the elasticity of the pulling rope material, the device cannot effectively maintain the ideal shape
