a system and method for wirelessly powering an electrosurgical device using a generator to generate a radio frequency energy field . a switch on the electrosurgical device sends a wireless signal to the generator , where the generator allows a current to pass through an inductive coil to generate the rf energy field . the rf energy field induces a current to flow across an inductive coil within the electrosurgical device . the current flow is then processed through a rf conditioning circuit and outputted to the end effector assembly of the device .
