US Patent 6958063 Plasma generator for radio frequency surgery

The present invention furnishes a plasma generator for generating a cold plasma jet beam in the application field of medicine and in particular of surgery as well as other fields of science. The plasma generator is furnished with a separate, frequency tunable oscillator, wherein the frequency tunable oscillator controls the power end stage through a driver stage. The radio frequency of the outpout of the generator is determined by a resonance frequency of a resonance transformer. The plasma current is limited by a capacitor disposed in the hand piece.
