Working principle of plasma knife: The plasma module excites the electrolyte (normal saline) to form a plasma thin layer with the thickness of 100 μm around the electrode through a 100 kHz RF electric field. The plasma thin layer is composed of a large number of charged particles, producing enough energy (electron volt) to open the molecular bonds constituting the target tissue cells at a lower temperature, so that the tissue is rapidly decomposed into molecules and atoms with low molecular weight, thus forming an efficient tissue ablation, cutting and coagulation effect at a lower temperature. Since plasma has the same cutting effect as "knife", it is also clinically called "plasma knife".

· Percutaneous endoscopic lumbar disc herniation treatment: extra-discal ablation, direct decompression, safe and efficient, with wide indications
