How to make a high frequency knife for surgery

High-frequency electric knife since 1920 applied to clinical so far, has a history of more than 90 years. It has experienced a spark plug discharge - high-power electronic tube - high-power transistor - high-power MOS tube four generations of change. With the popularization, application and development of computer technology, the implementation of a variety of functions under the power waveform, voltage, current automatic adjustment, the detection of various safety indicators, as well as programmed control and fault detection and indication. Thus, it greatly improves the safety and reliability of the equipment itself and simplifies the operation process of doctors.

At the same time, with the development of medical technology and clinical requirements, high-frequency scalpel-based composite electrosurgical equipment has developed accordingly: high-frequency argon knife, high-frequency ultrasound surgical system, high-frequency electrocutaneous endoscopic treatment system, high-frequency rotary cutting and degreasing machine and other equipment, in the clinic have achieved remarkable results. And with the derivation of a variety of high-frequency surgeon special accessories (such as: bipolar electrocutaneous scissors, bipolar electrocutaneous mirrors, electrocutaneous mirrors, vaporizing roller electrodes, etc.) has also developed a wider range of use for clinical surgery.

Classification

Listen to the voice

Based on the function and use of high-frequency surgeon, can be broadly divided into the following types:

1, multi-functional high-frequency electrosurgical knife: with a pure cut, mixed cuts, unipolar coagulation, electrocautery, bipolar electrocoagulation;

2, unipolar high-frequency electrosurgical knife: with a pure cut, mixed cuts, unipolar electrocoagulation, electrocautery;

3, bipolar Electrocoagulator: bipolar electrocoagulation;

4, electrocautery: unipolar electrocautery;

5, endoscopic special high-frequency generator: with pure cut, mixed cut, unipolar electrocoagulation;

6, high-frequency argon knife: with argon protection cutting, argon arc jet coagulation;

7, multi-functional high-frequency cosmetic instrument: with a point of coagulation, a point of cauterization, ultra-high-frequency electrocautery.

Basic Composition

Listen to the voice

High-frequency electrocautery is composed of the host and electrocautery knife handle, the patient pole plate, bipolar tweezers, foot switch and other accessories.

Principle of operation

Listen to the voice

The HF scalpel has two main modes of operation: monopolar and bipolar.
