Bipolar scissors

Abstract

The invention relates to a bipolar scissors, which is mainly suitable for surgical operation. The bipolar scissors includes a scissor head assembly, a tong rod assembly and a handle assembly. The scissor head assembly comprises an active scissor blade, a loop electrode blade, a passive scissor blade, a pull rod, a pull rod insulating tube, a support frame insulating sleeve, a support frame and a pull rod joint. The passive scissor blade is made of an insulating material, and is positioned between the active scissor blade and the loop electrode blade and insulates the active scissor blade and the passive scissor blade only contacts with the active scissor blade edge. Also provided is a jaw bar assembly connected with a handle assembly, a scissor head assembly passing through the jaw bar assembly, and a front end of the jaw bar assembly and the scissor head assembly are internally threaded. The structure design of the invention is more reasonable, can be disassembled and cleaned, can withstand high temperature and high pressure sterilization, and can be repeatedly used for many times. At that same time, the invention is suitable for human endoscopic operation, reduce the operation risk, has good effect of removing pathological tissue and blood coagulation, shorten the postoperative recovery time of patients, and is safe and reliable to use.

Description

technical field [0001] The invention relates to a kind of medical scissors, in particular to a kind of bipolar scissors, which belongs to the field of medical technology and is mainly suitable for human body surgery. Background technique [0002] In the prior art, medical electrocoagulation scissors are divided into two types: monopolar and bipolar, and are mainly used for cutting and coagulating human tissues in surgical operations, so as to control and reduce bleeding while separating human tissues. [0003] When working with unipolar scissors, the negative electrode needs to be in contact with the human body, and the high-frequency electric energy extensively passes through the human body and has a certain impact on the human heart; at the same time, glucose is used as the flushing medium during the operation, and diabetics are prone to TURP syndrome, that is, water intoxication. And the required power is large, the heat diffusion range is large, and the damage to the sur...

AI Technical Summary

Problems solved by technology

Bipolar scissors and low-temperature electrocoagulation scissors with this structure have the following disadvantages in use: 1. They are not suitable for repeated use, cannot be disassembled and cleaned, and cannot withstand high temperature and high pressure sterilization; 2. The outer jacket on the electrode hub is heat-shrinkable and insulated Tube, affects scissors opening angle and handle operation

Although bipolar scissors with this structure can electrocoagulate hemostasis during surgery and are suitable for human endoscopic surgery, they still have the following disadvantages when used: the structure is not suitable for repeated use, cannot be disassembled and cleaned, and cannot withstand high temperatures Autoclave
