Abstract
An electrosurgical system having an electrosurgical device, an accessory charging circuit, and an electrosurgical unit is disclosed. The electrosurgical device is operable in at least one of a monopolar mode and a bipolar mode. The electrosurgical unit electrically is coupled to the electrosurgical device and the accessory charging circuit. The electrosurgical unit provides one of a monopolar RF energy signal and a bipolar RF energy signal to the electrosurgical device corresponds with an activated mode and a bipolar signal to the accessory charging circuit.
