Laparoscopic surgery smoke exhaust device

Abstract

The invention belongs to the technical field of smoke exhaust devices, particularly relates to a laparoscopic surgery smoke exhaust device and aims at solving the problem that a Veress needle is utilized for air extraction, enterocoelia can contract at the same time although smoke in the enterocoelia is thoroughly exhausted, and an operation space for a surgery is destroyed of an existing manner of removing surgical smoke. Now the following technical scheme is provided, the laparoscopic surgery smoke exhaust device comprises a lying plate; a connecting plate is fixedly installed on the top ofthe lying plate; a fixed plate is fixedly installed on one side of the connecting plate and is provided with a fixed cavity; fixed grooves are formed in the inner wall of the top and the inner wall ofthe bottom of the fixed cavity respectively; one fixed rod is fixedly installed on the inner walls of the two sides of each fixed groove; the two fixed rods are provided with one sliding plate in a sliding manner; one ends of springs are fixedly installed on one side of the sliding plate; and the other ends of the springs are fixedly installed on the inner walls of one sides of the fixed groovesrespectively. The laparoscopic surgery smoke exhaust device is simple in structure and convenient to use and can facilitate the situations that the smoke in a belly of a patient is exhausted, and airpressure in the belly can be kept constant.

Description

Technical field [0001] The invention relates to the technical field of smoke evacuation devices, in particular to a smoke evacuation 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 through a small incision can be said to be a small wound and less painful operation; do the abdominal cavity During endoscopic surgery, the doctor will cut an 8mm hole in the patient’s abdomen, insert a pneumoperitoneum, and inject an appropriate amount of carbon dioxide gas to expand the abdominal cavity to form an operating space. Punch two or three small holes in the other part of the stomach to insert a camera-like eyepiece and surgical instruments illuminated by a laser beam. Turn the eyepiece from all angles, and the doctor can clearly see the internal organs on the TV screen. This is the case; electrosu...

AI Technical Summary

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
