Multifunctional shear-type high-frequency electrotome capable of reducing heat damage

Abstract

The invention discloses a multifunctional shear-type high-frequency electrotome capable of reducing heat damage. The multifunctional shear-type high-frequency electrotome comprises a left handle and aright handle, a lower connecting rod is connected with an upper connecting rod through a rotating shaft, upper and lower jaws are arranged at front ends of the upper and lower connecting rods respectively, the left handle comprises a left handle upper cover and a left handle lower cover, a touch type switch and the lower connecting rod are fixed on the left handle lower cover, a cylinder on a stop hook is fixed in a round hole of the lower connecting rod, a stop piece is connected with the stop hook and the lower connecting rod separately, two ends of a spring are connected with the lower connecting rod and a trigger baffle respectively, the trigger baffle is connected with a trigger and an oscillating bar separately, and the oscillating bar is connected with a blade; the upper jaw consists of a front end of the upper connecting rod, a plastic encapsulation layer and an upper electrode plate; the lower jaw consists of a front end of the lower connecting rod, a plastic encapsulation layer and a lower electrode plate; and the upper jaw and the lower jaw are combined to be in a duckbill shape, and an insulating bulge point is arranged at the lower end of the upper jaw. The multifunctional shear-type high-frequency electrotome is simple in structure and reasonable in design, and improves the solidification effect of tissue and shortens the operation time.

Description

technical field [0001] The invention relates to a high-frequency electric knife, in particular to a multifunctional scissor-type high-frequency electric knife that can reduce heat damage. 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. Because of its extremely fast cutting, good hemostasis effect, and automatic disinfection of the wound side, it can greatly shorten the operation time, reduce the blood loss of patients, and thereby reduce complications. At present, the high-frequency electric knife has basically replaced the mechanical scalpel. However, the high-frequency electrosurgical knife generally has a fast thermal...

AI Technical Summary

Problems solved by technology

However, the high-frequency electrosurgical knife generally has a fast thermal diffusion during use, which is easy to cause thermal damage to surrounding tissues, and will reduce the coagulation effect of the target tissue and prolong the operation time
