Built-in aspirator for laparoscopic surgery

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 devices, in particular to a built-in aspirator for laparoscopic surgery. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, and it is an inevitable trend in the development of future surgical methods. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open operations in the past have now been replaced by endovascular surgery. Greatly increased surgical options. The traditional method of retroperitoneal laparoscopic surgery is to make three small incisions of 1 cm on the patient's waist, each inserting a tube-shaped working channel called "trocar", and all subsequent operations are performed through these three channels; and then special lengthened surgical instr...

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
