Abstract: A high-frequency generator for high-frequency surgery is driven by a d.c. voltage supply. This d.c. voltage supply has a first working mode for transferring energy in a direction of the high-frequency generator, and also a second working mode for transferring energy in an opposite direction. With this arrangement, a particularly fast and efficient regulation of output voltage of the generator is possible. Therefore a reliable first cut may be performed on different kinds of tissue without any coagulation. Furthermore, owing to a high efficiency, a particularly small constructional size can be achieved.

Abstract: A high-frequency generator for high-frequency surgery comprises a power generator for supplying high frequency energy at a base frequency. A standardizing factor is determined, with which an output variable from the power generator must be scaled in order to attain a given desired value. Furthermore, harmonics of the base frequency are determined from the output variable and scaled using this factor. By means of an input, the thus obtained signal now controls the output power of the generator. With this arrangement, a reliable first cut may be performed on various kinds of tissue without occurrence of any coagulation.

Abstract: The invention refers to a device for monitoring the application of a neutral electrode in unipolar HF surgery, having an impedance sensor with a resonant circuit comprising a secondary coil of a transformer and HF input capacitors of preferably two partial electrode surfaces. The impedance sensor detects the transient impedances of two partial electrode surfaces connected in series with the patient's tissues by application of a patient auxiliary current and is moderated by the transition impedances. The invention is characterized in that the resonant circuit is excited by alternating voltages of variable frequencies in the range of a resonant frequency, and in that a peak value detector is provided which detects an alternating voltage peak value at the resonant frequency. The disclosed device excites the resonant circuit in such a manner that a faultless measurement of the transition impedance at the level of the patient's tissues is made possible.
