Sleeved gasless single-hole operating platform for laparoscopic surgery

Abstract

The invention discloses a sleeved gasless single-hole operating platform for laparoscopic surgery. The sleeved gasless single-hole operating platform comprises a single-hole channel, a suspension umbrella, a mechanical arm and a fixed rod, wherein the suspension umbrella is suspended on the mechanical arm; the mechanical arm is installed on the fixed rod; the single-hole channel is composed of a main tube and an extension tube; a porous disc for surgical instruments to pass in and out is arranged in the middle of the main tube in the single-hole channel; the single-hole channel of the platform is sleeved in the suspension umbrella; the single-hole channel is connected with a lower ring of the suspension umbrella by joints at two lower sides of the main tube; an upper ring and the lower ring of the suspension umbrella are elliptical; the single-hole channel is sleeved in the middle of the upper ring and the lower ring; and the middle joint of a spoke is in spring connection. With the adoption of the operating platform, the laparoendoscopic single-site surgery and gasless surgery can be organically combined, thus the disadvantage that the prior gasless laparoendoscopic single-site surgery has small operation space and bad surgical field exposure is overcome; and meanwhile, operation of the gasless laparoendoscopic single-site surgery is simplified so as to be easier to popularize and use.

Description

technical field [0001] The invention relates to the field of laparoscopic minimally invasive surgery, in particular to a set-in type pneumoperitoneum-free single-hole operating platform for laparoscopic surgery. 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. Laparoscopic surgery routinely uses CO2 insufflation technology to create a surgical operating space. Because CO2 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, the existing pneumoperitoneum-free technology includes the Japanese "Kirschner wire" pneumoperitoneum-free device represented by Shanghai Island Medical Group, the fan-type abdominal...

Problems solved by technology

[0007] The purpose of the present invention is to provide a laparoscopic operation with a single-hole operation platform without pneumoperitoneum, which organically combines the laparoscopic single-hole technology and the non-pneumoperitoneum technology, which can overcome the existing operation space of the pneumoperitoneum-free technology. The shortcomings of small size and poor exposure of the surgical field, and the advantages of more minimally invasive and more aesthetically pleasing single-port technology, and simplifies the operation steps of laparoscopic pneumoperitoneum-free single-port surgery, making it easier to promote and apply
