ABSTRACT:
An electrosurgical device in which high frequency electrical energy powers a cutting electrode. Radio frequency energy is set up in a driver coil and a driven coil mounted in a handpiece. The driver coil energizes the driven coil to energize a surgical electrode connected to one end of the driven coil. Connection between the source of radio frequency energy and the driver coil includes a circuit in which condensers and impedances are so connected that, if there is a failure of the condensers, energy is dissipated.
