ABSTRACT:
A radiofrequency electrosurgical device which includes an active electrode and a passive electrode coupled to a chassis ground of a radiofrequency generator of the device. If the passive electrode is disconnected from the chassis ground, a potential develops between the chassis ground and a system ground. This potential is used to actuate a relay to disable the radiofrequency generator if the passive electrode becomes disconnected.
