Abstract
The present invention relates to a high-frequency surgical generator (1) for adjusted cutting and coagluation having adjustment devices for setting the momentary electric output values, such as, e.g., current, voltage and power and having a device for direct and/or indirect determination of the state of the tissue in the vicinity of the cutting electrodes. The present invention is distinguished by a time-interval transmitter and electronic desired-value transmitters being provided and one mode of operation of at least two different modes of operation having different operative purposes being selected in successive time intervals and an electronic memory having evaluation electronics, to which the output value of the measurement device is transmitted and the output signal of the evaluation electronics is transmitted to the electronic desired-value transmitters in conjunction with the output value of the measurement device with the aid of which the temporal course of the electric output values of the high-frequency generator for the selected mode of operation are suitably set.
