[0028] By installing an isolation net 105 inside the electrode mounting seat 104, larger tissue fragments generated during the operation will be blocked by the isolation net 105 before entering the suction tube 106. This area is in the working area of the plasma electrode, and the tissue fragments will be further decomposed into particles or carbon dioxide and water here, thereby ensuring that the suction tube 106 will not be blocked.
