The plasma surgical device is a cryogenic electrosurgical device used for soft tissue cutting and coagulation, which can reduce intraoperative bleeding and reduce thermal damage to surrounding tissues.
Technical Principle:
Plasma surgery equipment through the low-frequency stable electric field (about 100kHz) to stimulate saline into low-temperature plasma, the front end of the electrode to form a thin plasma layer with a thickness of about 100 μm. Charged particles in the electric field to accelerate the movement, get enough kinetic energy to break the molecular bond, so that the tissue decomposition, vaporization or cutting, and produce coagulation effect. Since the operating temperature is only 40~70 ℃, the thermal damage to the surrounding normal tissues is minimal.
