Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a filter puncturer for laparoscopic surgery. Background technique [0002] With the continuous improvement of living standards, laparoscopic surgery is increasingly favored, and more and more widely concerned and applied. The laparoscopic puncture device commonly used in the market is used to establish a channel for surgical instruments. It has the advantages of small abdominal opening of the patient and easy healing of the wound surface, so it can realize minimally invasive surgery. Minimally invasive surgery has developed from a single inspection and drug administration in the early days to more modern surgical operations. Now that surgical operations are prevalent, various surgical tools have been produced. In almost all surgical operations, there are It is necessary to use active medical devices such as electric knife, electrocoagulation, electric hook, etc., whi...
