Abstract: An electrosurgical generator, a control device, a method for operating the electrosurgical generator and a computer program product. The electrosurgical generator includes an ultrasonic generator for providing an excitation signal by which an ultrasonic converter can generate an ultrasonic vibration, a radiofrequency generator for providing a radiofrequency energy at two output contacts, and a control unit adapted to independently activate the radiofrequency generator and the ultrasonic generator. The control unit is further adapted to determine a DC-offset voltage between the two output contacts of the radiofrequency generator, check if the DC-offset voltage exceeds a DC-offset threshold value, and deactivate the ultrasonic generator if the DC-offset voltage does not exceed the DC-offset threshold.

Abstract: A medical device includes: a housing; a switch provided on the housing; and a converter provided in the housing. The switch is configured to allow switching between a plurality of states and is configured to output a first signal in response to one of the states to which the switching is performed. The converter is configured to convert the first signal into a second signal of a different system when the converter receives the output of the first signal, and is configured to output the second signal to an outside configured to detect the second signal.
