Electrocoagulator high-frequency scalpel (high-frequency scalpel) is a kind of electrosurgical instrument that replaces mechanical scalpel for tissue cutting. It heats the tissue when it comes into contact with the muscle through the high-frequency, high-voltage current generated by the tip of the effective electrode, realizing the separation and coagulation of the muscle tissue, thus serving the purpose of cutting and hemostasis .
The high-frequency electric knife has been used in clinical practice since 1920, and has a history of more than 70 years. It has experienced a spark plug discharge - high-power tubes - high-power transistors - high-power MOS tube four generations of change. With the popularization, application and development of computer technology, at present, high-performance microcontroller is widely used in the high-frequency electrosurgical knife machine control, the implementation of a variety of functions under the power waveform, voltage, current, automatic adjustment, a variety of safety indicators, as well as the detection of 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.
