Abstract
High-frequency device to generate a plasma arc ( ) for the treatment of biological tissue ( ), in particular in medicine, with a high-frequency generator ( ) having an internal resistor ( ) and, connected thereto by means of a flexible lead ( ), an electrode ( ) with which the plasma arc ( ) is produced in a plasma segment ( ) between the electrode ( ) and the biological tissue ( ), which is likewise electrically connected to the high-frequency generator ( ), such that in the high-frequency generator ( ) a high-frequency voltage source ( ) is provided to which is connected a resonant circuit ( ) that comprises a first reactance element ( ) with a capacitive action and, in series therewith, a second reactance element ( ) with an inductive action, and that has a resonant frequency at the frequency of the high-frequency oscillation emitted by the high-frequency voltage source ( ), wherein the voltage to generate the plasma arc ( ) is derived from the first or second reactance element ( ).
