Claim 0:
1. An electrosurgical system, comprising:
an electrosurgical device operable in at least one of a monopolar mode, via a received monopolar RF energy signal of at least one of a first power waveform and a second power waveform and a bipolar mode, via a received bipolar RF energy signal of a third power waveform, wherein the first power waveform, the second power waveform and the third power waveform each provide different power levels and frequency ranges;
an accessory charging circuit operably coupled to an accessory, the accessory charging circuit having an energy storage element and to receive a bipolar signal of a fourth power waveform and to store electrical energy in the energy storage element, the fourth power waveform below an RF range relative to the first, second, and third power waveforms, the accessory charging circuit operable via the energy storage element to provide power to the accessory; and
an electrosurgical unit having a bipolar receptacle and a monopolar receptacle disposed on an exterior housing of the electrosurgical unit, the bipolar receptacle being coupled to the electrosurgical device and the accessory charging circuit via a plug and the electrosurgical device and the accessory charging circuit in parallel to the electrosurgical unit,
the electrosurgical unit providing one of the monopolar RF energy signal of at least one of the first power waveform and the second power waveform as an output via the monopolar receptacle, and the electrosurgical unit providing the bipolar RF energy signal of the third power waveform to the electrosurgical device corresponding with an activated mode and the bipolar signal to the accessory charging circuit of the fourth power waveform as an output via the bipolar receptacle;
wherein the electrosurgical unit outputs the bipolar RF energy signal and not the bipolar signal from the bipolar receptacle to be received by the electrosurgical device when in the activated mode and the electrosurgical device outputs the bipolar signal and not the bipolar RF energy signal from the bipolar receptacle to the accessory charging circuit when not in the activated mode.
