Under the low frequency electric field of 100KHz, a plasma thin layer with a thickness of about 100 μm is formed around the electrode by normal saline. The plasma thin layer is composed of high-energy ions. These particles have enough kinetic energy to break the organic molecular bonds of the target tissue and make it vaporized and cracked into gas. The low-temperature plasma technology can realize the functions of tissue cutting, ablation and coagulation at a low temperature of 40-70 C, which effectively avoids defects of high temperature, deep damage, and excessive bleeding.
Operating at 100kHz, this system maintains a working temperature of approximately 40-70°C. This results in shallow damage depth and significantly faster postoperative recovery. During surgery, the coagulation effect is excellent with minimal bleeding and reduced patient pain compared to traditional 300khz-600khz systems.
