Electro surgery summary

When the high-frequency and high-voltage current generated by high-frequency electrosurgery unit

passes through high-impedance tissue, it will generate heat in the tissue, causing the tissue to vaporize or solidify.

High-frequency electrosurgery uses the high-frequency and high-voltage current generated by the effective electrode tip 

to heat the tissue when it comes into contact with the body, thereby achieving the separation and coagulation of body tissue, thereby achieving the purpose of cutting and stopping bleeding.

During electrosurgical use, the resistance varies from 100 ohms to 2000 ohms. As the tissue solidifies, 

the water in the cells vaporizes, drying out the tissue, causing resistance to increase until the current 

flow stops altogether.
