Folding-fan-type peritoneoscope gasless device

Abstract

The invention relates to the filed of peritoneoscope minimally invasive surgery, in particular to a folding-fan-type peritoneoscope gasless device which can overcome the defects that an existing gasless technology is small in operation space, and poor in operative filed exposure. The folding-fan-type peritoneoscope gasless device is composed of a fixing support, a hanging arm and a folding fan mechanism. An opening-closing method of a folding fan is adopted to realize unfolding and folding of blades, the folding fan mechanism is used for enabling the blades to open one by one in a rotary mode and to form a folding fan shape so as to lift abdominal walls. A front abdominal wall is lifted and hung through the blades which are in the shape of a folding fan, and therefore the problem that the existing gasless technology is not enough in exposure in operation space is solved.

Description

Technical field: [0001] The invention relates to the field of laparoscopic minimally invasive surgery, in particular to a folding fan type laparoscopic pneumoperitoneum device. Background technique: [0002] As a minimally invasive technique, laparoscopic surgery has become an important surgical method for tissues and organs such as liver, gallbladder, pancreas, spleen, stomach, intestine, abdominal wall hernia, uterus and ovaries. Traditional laparoscopic surgery uses CO 2 Pneumoperitoneum technology to create surgical operation space. Due to CO 2 Pneumoperitoneum has many adverse effects on the breathing, circulatory system and pregnant fetus. Various abdominal wall suspension devices have been developed to perform laparoscopic surgery without pneumoperitoneum. However, the existing pneumoperitoneum technology, including the Japanese Kirschner wire pneumoperitoneum device represented by Shanghai Island Medical Group, the airbag suspension device of Fu-Hsing Chang in Taiwan, th...

AI Technical Summary

Problems solved by technology

The main reason is that the suspension tension of the abdominal wall of the existing pneumoperitoneum-free technique will make the bilateral abdominal walls gather in the middle, squeeze the intestines and concentrate in the middle, resulting in a smaller and narrower operating space; when the muscle tension is greater, the operating space will be more crowded. Significantly reduced

In the field of laparoscopic minimally invasive surgery, the main reason why the pneumoperitoneum-free technique cannot be further developed is that the pneumoperitoneum-free technique has a small operating space and poor exposure of the surgical field.
