Abstract:
1. An HF surgical device with an autostart function for cutting and/or coagulating biological tissue with HF current, said HF surgical device comprising: an HF generator for generating the HF current; a selected output for connecting a monopolar or bipolar electrode to the HF surgical device; a first measurement device associated with the output and for measuring a first measured value for an impedance of the electrode connected to the output; a first comparator for comparing the first measured value to a first setpoint, for switching-off the first measurement device and for switching-on a second measurement device if the first measured value is lower than the first setpoint, and for measuring a second measured value for the impedance of the connected electrode; and a second comparator for comparing the second measured value to a second setpoint and for switching-on of the HF current for the output if the second measured value is lower than the second setpoint.
