A laparoscopic surgery built-in suction device

Abstract

A laparoscopic surgery built-in suction device includes a body, a flow duct, a thick conduit and a thin conduit, the upper end of the main body is provided with a connecting flange, a first conduit penetrating through the connecting flange is installed on the inner side of the connecting flange, second catheter, A rotating lever is mounted at the center of the inner side of the main body through arotating shaft, first movable conduits are respectively arranged on the inner sides of the two ends of the rotating lever, second movable catheter, the first movable catheter, the upper end of the second movable conduit is respectively connected with the first conduit, and the lower end of the second conduit is connected with the bellows. The outer sides of the lower ends of the first movable conduit and the second movable conduit are provided with liquid inlet holes. The outer side of the second movable conduit is provided with a fixing rod passing through the main body, and the fixing rod is provided with a finger ring near the outer end of the main body. The invention is convenient for fast switching between thick and thin conduits, and can effectively prevent the internal conduit of the device from being blocked.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a built-in aspirator for laparoscopic surgery. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method and an inevitable trend in the development of surgical methods in the future. With the rapid advancement of industrial manufacturing technology, the integration of related disciplines has laid a firm foundation for the development of new technologies and new methods. Coupled with the increasingly skilled operation of doctors, many past open surgeries have now been replaced by intracavitary surgeries. Greatly increase the chances of surgery options. The traditional method of retroperitoneal laparoscopic surgery is to make three small 1-cm incisions on the waist of the patient and insert a pipe-like working channel called "trocar" into each. All subsequent operations will be carried out through these three pipes; then special lengthened surgic...

AI Technical Summary

Problems solved by technology

[0004] 1. It is necessary to use a thick catheter or a thin catheter during use, and it is necessary to switch back and forth between the thick catheter and the thin catheter during the operation, resulting in a long operation time and inconvenient use;

[0005] 2. Due to the small diameter of the suction tube itself, the internal tube is easily blocked by blood clots and other objects during the suction process
