Laparoscope working casing pipe double-cleaning and gas leakage prevention device

Abstract

The invention relates to a laparoscope working casing pipe double-cleaning and gas leakage prevention device. One end of a connection rod is connected with a first cleaning ball, the edge of a second cleaning ball connected to the connection rod is tangent with the edge of the first cleaning ball, and the first cleaning ball and the second cleaning ball are made of water absorbing materials and are flexible. The laparoscope working casing pipe double-cleaning and gas leakage prevention device solves the problems that the cleaning range is small, a device needs to enter and get out of a working casing pipe many times, the cleaning effect and efficiency are affected, a casing pipe sealing cap is damaged, and gas leakage is caused in the prior art. The two adjacent cleaning balls can clean the casing pipe twice when entering and getting out of the casing pipe at a time, the potential safety hazard of residue of foreign matter in the body is eliminated, the second cleaning ball connected with the edge of the first cleaning ball stays in the working casing pipe when the first cleaning wall passes through an inner port of the working casing pipe and enters the body, gas is prevented from leaking effectively, operation suspension caused by pneumoperitoneum gas leakage is avoided, the gas consuming amount of an operation is reduced, and the total operation time is shortened.

Description

technical field [0001] The invention relates to a medical device, in particular to a double-cleaning and air-leakage-proof device for a laparoscopic working sleeve. Background technique [0002] An increasing number of surgical and gynecological procedures are performed laparoscopically or retroperitoneally. Laparoscopic surgery needs to establish a closed working space (pneumoperitoneum) in the body that is greater than the external atmospheric pressure. A 10mm diameter working sleeve is placed to connect the extracorporeal and internal space. During operation, when the laparoscopic mirror and surgical instruments enter and leave the body through the working sleeve, the fat tissue and blood stains in the body will be taken out, contaminating the working sleeve tube wall and the outer sealing cap. Especially the 10mm working cannula, which is usually used to place the laparoscopic mirror, is most likely to be contaminated by fatty tissue and blood; Dirt, which contaminates...

AI Technical Summary

Problems solved by technology

When cleaning the single ball device, it is necessary to pass the cleaning ball completely through the inner opening of the working sleeve to complete the full cleaning of the working sleeve. At this time, only the connecting rod remains in the working sleeve, and the diameter of the connecting rod is smaller than the inner diameter of the working sleeve. The casing sealing cap structure is broken, causing air leakage

[0006] 3. The above two defects of the practical single ball device will lead to gas leakage of the pneumoperitoneum

After insufflation, the operation needs to be suspended, and the gas should be injected into the abdominal cavity again to achieve the pressure required for the operation, which seriously consumes the operation time and the amount of operation gas, and increases the medical cost; especially when the operation is suspended when dealing with blood vessels or other important organs , may lead to serious adverse consequences
