ABSTRACT:
A high-frequency electrosurgery apparatus for cutting and/or coagulating biological tissues that may have a number of operating modes is described. As control panel on which one or more parameters of the high-frequency output of the apparatus can be set. Particularly important is the current-limiting system which includes setting of a desired maximal current level, to which for a particular mode of operation the current can be limited or in response to which a warning signal may be activated and/or the high-frequency generator shut down. The effective current that the application instrument reaches or exceeds previously set maximal current level. In such a high-frequency electrosurgery apparatus the cable leading to the active electrode is provided with electrial shielding which is connected to the conductor leading to the neutral electrode at a location between the output transformer of the apparatus and the current sensor of the current limiting system.
