Multifunctional bipolar high-frequency electric knife

Abstract

The invention discloses a multifunctional bipolar high-frequency electric knife, which comprises a handle, a first trigger and a second trigger. A lock sleeve is fixed in a lock sleeve groove in the handle, and a pin penetrates the lock sleeve and a middle tube main body for fixation of the middle tube main body, a clamp assembly is disposed at an end of the middle tube main body, a cutter bar assembly is disposed in the middle tube main body, the sleeve is sleeved on the outer side of the middle tube main body, two retaining rings are sleeved on the sleeve, a second spring is disposed betweenthe retaining ring near the protruding position of the sleeve and the sleeve, a third spring is disposed between the lock sleeve and a sleeve assembly, and the left end of the outer tube is screwed into the sleeve, a spinner card is arranged in a waist groove on the outer tube, a cutter bar ring sleeve and a first spring sleeve are sleeved on the outer tube, the knife bar ring is fixed on the outer tube through a ring penetrating shaft, and the clamp assembly is fixed at an end of the middle tube main body by a cutter head rivet. The electric knife has the advantages of simple structure and reasonable design, can simultaneously coagulate and cut the surgical site, shortens the operation time, reduces the operation risk, and improves the safety of the operation.

Description

technical field [0001] The invention relates to surgical equipment, in particular to a multifunctional bipolar high-frequency electric knife. Background technique [0002] A high-frequency electrosurgical device is an electrosurgical instrument that replaces a mechanical scalpel for tissue cutting. It heats the tissue when the high-frequency and high-voltage current generated by the effective electrode tip contacts the body, and realizes the separation and coagulation of the body tissue, thereby achieving the purpose of cutting and hemostasis. [0003] At present, hospitals use electrosurgical scalpels when performing thoracic and abdominal operations. It has fast cutting speed, good hemostasis effect, simple operation, safety and convenience. However, in the process of using electrosurgical surgery, the general bipolar high-frequency electrosurgical unit only has the function of electrocoagulation and cannot achieve cutting. The operation process is complicated and require...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems of frequent replacement of instruments in traditional surgery and the inability to realize cutting and coagulation at the same time, the present invention provides a bipolar high-frequency electric knife that can realize grasping, separation, electrocoagulation, pulling and cutting at the same time
