High-frequency surgical generator for cutting tissue
First Claim
1. A high frequency surgical generating system having a device for setting the maximum power output sufficient for tissue being operated on with respect to material detected at an operation site comprising:
- a high frequency generator having an output;
indicating means, said indicating means comparing a spectrum of power from said high frequency generator output influenced by electrical values dependent thereon;
said indicating means comparing the power spectrum of at least two different frequency ranges;
display means receiving and displaying an electric signal representing said power;
an evaluating circuit receiving an output from said indicating means, said evaluating circuit having a desire-value transmitter for setting a desired output value from said high frequency generator that is dependent upon a ratio of a plurality of output signals representing said at least two different frequency ranges from said indicating means.

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.
