Paper Abstract

We present the process controlling of a high-frequency surgery generator during tissue treatment. Hereby, the temporal behavior of the voltage and the current are measured and then the finger print of the generated light arc in the electrical characteristic is analyzed by the control unit. This unit forces the high-frequency generator to supply an appropriate electrical power for different kinds of tissue. The functional ability is verified by cuts with different set points of the controlled variable, therefore, different degrees of slough, and cuts through tissue heterojunctions.
