Dr.Oppel’s electrode is not being heated by itself. Electrode Let’s the cellular tissue produce the joule heat, and operates hemostasis, cutting, and coagulation. 4MHz radio frequency makes possible precise cutting and deep coagulation even in water. Moreover, coagulation depth is determined by electrode as 5mm, 3mm, and 2mm.
The distinctive functions from other electrosurgical units and lasers
What is RF coagulation?
It’s a way of coagulation necrosis to the 5mm depth of tissue, when the radio frequency current flows from electrode, passing tissue, to the patient plate, by producing joule heat on the tissue itself close to electrode. It’s very hard to make necrosis with cauterization or cryosurgery because no deep coagulation is capable. However, coagulation necrosis is perfectly achieved in the coagulation with radio frequency current because electrode Let’s the tissue itself produce joule heat.
Self-control of coagulation depth
The coagulative depth is decided by the electrode size and the device is designed to make different coagulation depth by the electrode size as below.
