Abstract

In electrosurgical apparatus for tissue desiccation and cutting, an electrosurgical generator has a series-connected output inductor which forms a series resonant circuit with the capacitance of the generator load, the load including an electrode unit and a cable coupled to the generator output. The series resonant frequency is typically 1.5 f where f is the operating frequency of the generator. A capacitor may be included, coupled between the conductors which connect bipolar electrodes to the generator, to increase the load capacitance. The effect of these measures is to boost the output voltage available for electrosurgical treatment, especially for tissue cutting.
