| 摘要 |
The invention relates to an HF surgical device having an autostart function for cutting and/or coagulating biological tissue by means of HF current, said HF surgical device comprising an HF generator (65) for producing the HF current, a selected output for connecting a monopolar or bipolar electrode (70, 71) to the HF surgical device, a first measuring device (5) associated with the output (15) for measuring a first measured value of an impedance of the electrode (70, 71) connected to the output (15), a first comparator (44) for comparing the first measured value to a first target value, for switching off the first measuring devices (5) and switching on the second measuring device (10) if the first measured value is less than the first target value, and for measuring a second measured value of the impedance for the connected electrode (70, 71), and a second comparator (50) for comparing the second measured value to a second target value and for switching on the HF current for the output (15) if the second measured value is less than the second target value. |
