Problems solved by technology

This method is relatively traditional. When the instrument is taken out from the puncture cannula, the "duckbill" sealing component will be turned over and deformed, and most of the "duckbill" sealing components have air leakage in clinical practice, which cannot be quickly Good guarantee of intracavitary pneumoperitoneum, so that the doctor's operating field of view is blocked, the operation time is prolonged, and the patient's pain is increased

Abstract

The invention belongs to the technical field of celiac minimally invasive surgical equipment and in particular relates to a laparoscope puncture outfit adopting a water sealing type structure. The laparoscope puncture outfit comprises a puncture part, a sleeve part, a locking part and a sealing part, wherein the sleeve pipe sleeves the puncture part; the locking part and the sealing part are arranged at the tail end of the sleeve part. The laparoscope puncture outfit adopting the water sealing type structure, provided by the invention, is ingenuous in structure; a water sealing mechanism and apurification pipe are additionally arranged on the basis of an existing puncture outfit, so that the sealing performance of the puncture outfit is improved and a phenomenon that the puncture outfit leaks gas is avoided; stable pneumoperitoneum in a celiac minimally invasive surgery process is ensured and the surgery time is shortened; the pains of patients are alleviated and the postoperative recovery time is reduced.

Description

technical field [0001] The invention belongs to the technical field of abdominal cavity minimally invasive surgical instruments, and in particular relates to a laparoscopic trocar adopting a water-sealed structure. Background technique [0002] Disposable puncture device is an important instrument in laparoscopic surgery. It is a supporting surgical instrument for thoracic cavity and laparoscopic surgery. It is suitable for thoracic cavity and laparoscopic examination. channel equipment. With the development of imaging technology and camera technology, in recent years, minimally invasive surgery represented by laparoscopic surgery has developed rapidly, especially in gynecology, general surgery and other operations involving the abdominal cavity, which are gradually changing from open surgery to intracavitary surgery. minimally invasive surgery. If minimally invasive surgery is used, it is necessary to ensure the airtightness of certain pneumoperitoneum and instruments in ...
