Abstract

The application provides a reusable ultrasonic surgical instrument. The reusable eultrasonic surgical instrument comprises a cannula assembly, a cutter bar, a base and a clamping driving assembly. The cannula assembly comprises a pair of clip forceps at the far end, an outer cannula and an inner cannula. The outer cannula, the inner cannula and the cutter bar are coaxially arranged. The near end of the pair of clip forceps is provided with two rotary shafts. One end of the two rotary shafts is rotatably connected with the pair of clip forceps and the other one rotary shaft is rotatably connected with the inner cannula. The cannula assembly can be detached towards the far end direction of the axis of the cutter bar from the base and the clamping driving assembly or can be installed on the base and the clamping driving assembly towards the near end direction of the axis of the cutter bar. The outer cannula is connected with the base through one or multiple first detachable structures. The inner cannula is connected with the clamping driving assembly through one or multiple second detachable structures. The reusable ultrasonic surgical instrument is advantaged by being simple in structure and low in cost.

Description

technical field [0001] The present application relates to a surgical instrument, in particular to a reusable ultrasonic surgical instrument. Background technique [0002] With the popularization of minimally invasive surgery, ultrasonic scalpel has become a routine surgical instrument. The ultrasonic knife uses an ultrasonic frequency generator to mechanically vibrate the knife head at a certain ultrasonic frequency, so that the water molecules in the tissue are vaporized, the hydrogen bonds of the protein are broken, and the cells are disintegrated, so that the tissue is cut or coagulated, and the blood vessel can also be closed. . The ultrasonic scalpel enables tissue cutting and coagulation to stop bleeding at the same time, and has less lateral thermal damage. [0003] The ultrasonic scalpel system is mainly composed of ultrasonic frequency generators, transducers and surgical instruments. Among them, the ultrasonic frequency generator sends out oscillating electrical...
