A High-frequency electrosurgical knife (high-frequency surgical instrument) is an electrosurgical instrument that replaces mechanical scalpels for tissue cutting. It heats the tissue through the high-frequency high-voltage current generated by the effective electrode tip when it is in contact with the body, so as to realize the separation and coagulation of the body tissue, so as to achieve the purpose of cutting and hemostasis.
Here is some application introduction:
High-frequency electrosurgery has been used in clinic for more than 90 years since 1920. It has undergone four generations of changes in spark plug discharge - high-power electronic tube - high-power transistor - high-power MOS tube. With the popularization, application and development of computer technology, the automatic adjustment of power waveform, voltage and current under various functions, the detection of various safety indicators, and the detection and indication of programmed control and faults have been implemented. Therefore, the safety and reliability of the device itself are greatly improved, and the operation process of the doctor is simplified.
At the same time, with the development of medical technology and the clinical requirements, the composite electrosurgical equipment based on high-frequency surgical instruments has also developed accordingly: high-frequency argon knife, high-frequency ultrasonic surgical system, high-frequency electrosurgical surgery Endoscope treatment system, high-frequency rotary cutting fat removal machine and other equipment have achieved remarkable results in clinical practice. The various high-frequency surgical accessories derived therefrom (such as: bipolar electric shears, bipolar resectoscopes, resectoscope vaporization roller electrodes, etc.) have also opened up a wider range of clinical operations.
