发明名称 Electrosurgical apparatus
摘要 The present invention relates to an electrosurgical cutting device for the cutting and/or coagulation of tissue with RF current. A cutting electrode and a patient plate are connectable to the terminals of a RF generator. A control system, using a condition change arising at the cutting area during cutting as a controlled value, serves to control the RF current produced by the RF generator as a manipulated variable. The invention is characterized in that, for control of the RF-voltage of the RF generator, the control system responds to d-c voltage that arises at the cutting area during cutting with the RF current.
