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.

Medical device and medical system

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.
