High frequency electrosurgical unit is an electrosurgical instrument that replaces mechanical scalpel for tissue cutting. It heats the tissue by contacting the body with the high-frequency and high-voltage current generated by the effective electrode tip, thereby achieving separation and solidification of the body tissue, thereby cutting and stopping bleeding. There are two main working modes of high-frequency electrosurgical unit: monopolar and bipolar.
According to the function and use of the high frequency surgical instrument, it can be roughly divided into the following types:
1, multi-function high-frequency electrosurgical unit: with pure cutting, mixed cutting, monopolar coagulation, electrocautery, bipolar coagulation;
2, monopolar high-frequency electrosurgical unit: with pure cutting, mixed cutting, monopolar electrocoagulation, electrocautery;
3, bi-active coagulation set: bipolar electrocoagulation;
4, electric cautery: unipolar electrocautery;
5, endoscope special high frequency generator: with pure cutting, mixed cutting, monopolar electrocoagulation;
6, high-frequency argon knife: with argon protection cutting, argon arc jet coagulation;
7, multifunctional high-frequency beauty apparatus: with point condensation, point burning, ultra-high frequency electric burning.
