Air-inflation-type cut protection casing without pneumoperitoneum laparoscope

Abstract

The invention relates to an air-inflation-type cut protection casing without a pneumoperitoneum laparoscope. The casing comprises a sleeve and a supporting arm arranged on the outer wall of the sleeve. The casing is characterized in that an upper fixing ring and a lower fixing ring sleeve the outer wall of the sleeve, the supporting arm is arranged below the lower fixing ring and is a flexible supporting arm with a hollow interior, and an air inflation tube for conducting air inflation on the supporting arm is arranged on the supporting arm; a lifting and pulling part for upwards lifting and pulling the supporting arm is further arranged on the supporting arm, and the force application end of the lifting and pulling part is located above the upper fixing ring. The cut protection casing issimple in structure, convenient and safe to operate and low in manufacturing cost, after the supporting arm is subjected to air inflation, a certain area of an abdominal wall around a cut can be suspended effectively, the suspension effect of the whole abdominal wall is good, the good visual field is provided for the surgery, a laparoscope surgical instrument enters the abdominal cavity in the cutthrough the central space of the casing, and the injury to the abdominal wall of a patient during surgery is reduced to the greatest limit.

Description

technical field [0001] The invention relates to the field of laparoscopic surgical instruments, in particular to an inflatable incision protective cover for pneumoperitoneum-free laparoscopy. 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 technique can produce CO 2 Artificial pneumoperitoneum provides the space required for surgical operations, but due to CO 2 Pneumoperitoneum can be secondary to complications such as hypercapnia, air embolism, and blood stasis, which limits the application of this technique in children with immature tissues and organs, pregnant women, and elderly patients with underlying diseases. Pneumoperitoneum-free laparoscopy is an important technology in the field of minimally invasive, using external mechanical tension to provide operation space for surgery, without relying on artificial pneumo...

AI Technical Summary

Problems solved by technology

However, this technology has the following disadvantages: when using this device to perform pneumoperitoneum-free surgery, the maximum angle of intersection between the two laparoscopic surgical instruments that cooperate with each other is limited to a certain extent by the device, because the upper annular air bag made of elastic material There must be a considerable height when the lower annular airbag and the middle connecting part perform abdominal wall suspension stretching under working conditions. The greater the height is, the less flexible the instrument operation of laparoscopic surgery is. Abdominal wall suspension devices usually provide vertical upward traction To realize the suspension of the abdominal wall, and after the laparoscopic surgical instruments enter the abdominal cavity through the incision, more space needs to be oblique to the inner surface of the abdominal cavity instead of vertically downward and only limited to the operation directly below the incision

However, this technology has the following disadvantages: the device needs to be vertically inserted into the abdominal cavity to a certain depth in the folded state before the support arm can be opened in an umbrella shape through the pull rope, and the space in the abdominal cavity is limited. Blindly inserting the device and further expanding it around may cause damage to the intestinal tract; The reason for the design of the device is that the diameter and height are small, which results in a small displacement of the pulling rope sliding over the fulcrum during the process from the device being folded to the opening of the device. Due to elasticity, the device cannot effectively maintain the ideal shape

That is to say, the effectiveness and security of this technical solution are poor in practical applications
