Abstract
An electrosurgical unit including a radiofrequency generator configured to generate electrosurgical energy. The radiofrequency generator includes a first receptacle configured to electrically couple with an electrosurgical hand piece configured to deliver bipolar radiofrequency energy. A second receptacle is included and configured to electrically couple with an electrosurgical hand piece configured to deliver monopolar radiofrequency energy. The radiofrequency generator includes a relay circuit configured to allow simultaneous radiofrequency energy delivery to the electrosurgical hand pieces in the first receptacle and the second receptacle.
