Spindly non-pneumoperitoneum device for single-port laparoscopy

Abstract

The invention relates to the field of laparoscopic micro-invasive surgery, in particular to a spindly non-pneumoperitoneum device for a single-port laparoscopy. According to the spindly non-pneumoperitoneum device, the defects of small surgery space, poor surgical field exposure and great quantity of abdominal incisions in a traditional non-pneumoperitoneum technology can be overcome. The spindly non-pneumoperitoneum device consists of a fixed frame, a suspension mechanism and a spindle mechanism. Due to the adoption of the technical scheme that a support ring enables spindly spokes to be stretched off and be arrayed in an umbrella shape by upwards lifting a suspender, an anterior abdominal wall is semi-spherically lifted and suspended by the spokes arrayed in an umbrella shape and the phenomenon that the surgery space becomes smaller and narrower due to the fact that abdominal walls on two sides gather towards the middle to extrude intestinal canal to be concentrated to the middle by a suspending pull force of the abdominal walls is avoided; due to adoption of single incision in umbilical region, an illuminating probe, surgical instruments and the like extend into an abdominal cavity for surgery by using a hollow structure of the device; and due to the adoption of a rotational suspension device, the surgical instruments obtain a more favorable operation angle and the problems of small surgery space, insufficient surgical field exposure and great quantity of abdominal incisions in the traditional non-pneumoperitoneum technology are better solved.

Description

Technical field: [0001] The invention relates to the field of laparoscopic minimally invasive surgery, in particular to a spindle-shaped single-hole laparoscopic pneumoperitoneum-free 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 ovary. Traditional laparoscopic surgery using CO 2 Pneumoperitoneum technique to create surgical operation space. Due to CO 2 Pneumoperitoneum has many adverse effects on breathing, circulatory system and pregnant fetus. Various abdominal wall suspension devices have been developed to perform laparoscopic surgery without pneumoperitoneum. However, there are existing pneumoperitoneum-free technologies, including Japan’s Kirschner wire pneumoperitoneum-free device represented by Shanghai Island Medical Group, the air bag suspension device o...

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.

In addition, the existing pneumoperitoneum-free technology basically adopts porous technology, that is, three or four incisions need to be made on the abdomen during the operation so that the pneumoperitoneum-free device, lighting probe, surgical instruments, etc. can be inserted into the abdominal cavity for surgery. It is easy to cause postoperative pain, incision infection and incision hernia, and there are many scars in the abdomen after operation, which affects the appearance
