Claim Text:
1. A high frequency surgical device for generating a high frequency voltage for cutting or vaporizing of biological tissue during operations within a flushing liquid, the high frequency surgical device comprising: two output contacts at which an electrosurgical instrument is connectable and between which the high frequency voltage is provided during the operations; a parallel resonant circuit which is electrically connected with the two output contacts and in which the high frequency voltage is generated during the operations, wherein the high frequency voltage is configured for igniting an electric arc within the flushing liquid at the electrosurgical instrument, wherein a voltage limiter is arranged between the parallel resonant circuit and the two output contacts, wherein the voltage limiter is arranged parallel to the two output contacts, and wherein a voltage measuring device is arranged in parallel to the voltage limiter and the two output contacts, said voltage measuring device being distinct from said voltage limiter.
