ABSTRACT:
The present invention relates to high-frequency generator for cutting tissue having adjustment devices, with which at least one of the momentary electric output values, such as e.g., current, voltage, power or electric arc can be set.
The present invention is distinguished by, for improvement of the initial incision behavior, an electronic desired-value transmitter and a measurement device having an evaluation unit for direct and/or indirect determination of cutting being provided and said electronic desired-value transmitter providing upon commencement of an incision a particularly suited generator setting for the initial incision as long as said measurement device signals tissue-separating cutting of the probe and thereupon providing a lower desired value for the generator in such a manner that normal cutting corresponding to the desired surgical goal ensues.
