A smoke exhaust device for laparoscopic surgery

Abstract

The invention belongs to the technical field of smoke exhaust devices, in particular to a smoke exhaust device for laparoscopic surgery. The existing method for removing surgical smoke is to use a Veress needle to exhaust the smoke in the abdominal cavity, but at the same time It will also cause the abdominal cavity to shrink and destroy the operating space of the operation. The following scheme is proposed now, which includes a lying board. There is a fixed cavity, the top inner wall and the bottom inner wall of the fixed cavity are provided with fixed grooves, the same fixed rod is fixedly installed on the inner walls of both sides of the fixed groove, and the same slide plate is slidably installed on the two fixed rods, one side of the slide plate One end of the spring is fixedly installed, and the other end of the spring is fixedly installed on one side inner wall of the fixing groove. The invention has the advantages of simple structure and convenient use, and can conveniently discharge the smoke in the patient's stomach and maintain the constant air pressure in the stomach.

Description

technical field [0001] The invention relates to the technical field of smoke exhaust devices, in particular to a smoke exhaust device for laparoscopic surgery. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive surgery. Compared with the larger incisions required in the traditional surgical process, the operation in the abdomen is performed through small incisions, which can be said to be less invasive and less painful. During endoscopic surgery, the doctor will cut a small hole of 8 mm in the patient’s abdomen, insert a Veress needle, inject an appropriate amount of carbon dioxide gas, and stretch the abdominal cavity to form an operating space. Two or three small holes are made in another part of the stomach, and a camera-like eyepiece illuminated by a laser beam and surgical instruments are inserted into it. By turning the eyepiece from various angles, the doctor can see the internal organs of the stomach very clearly on the TV scre...

Problems solved by technology

[0004] The purpose of the present invention is to solve the existing method of removing surgical smoke in the prior art, which is to use a Veress needle to exhaust the smoke in the abdominal cavity, but at the same time it will also shrink the abdominal cavity and destroy the operation space of the operation. It is necessary to re-inflate the abdominal cavity through a Veress needle to continue the operation. This method not only affects the operation, but also greatly increases the burden of the doctor's operation and increases the operation time. A smoke exhaust device for laparoscopic surgery is proposed
