ABSTRACT:
An electrosurgical handpiece applies electrical energy to a blade electrode to accomplish blade electrosurgery or to a transfer electrode in a nozzle to transfer electrical energy in arcs in a flowing gas to accomplish conductive gas electrocoagulation. The blade electrode may be selectively extended to conduct blade electrosurgery and withdrawn when conductive gas electrocoagulation is accomplished. Finger activated switches on the handpiece control the application of electrical energy to the blade electrode and the application of gas to the nozzle and the electrical energy to the transfer electrode within the nozzle. A cord includes a tubing for supplying gas to the handpiece. The cord also includes a plurality of conductors for conducting electrical energy to the two electrodes and conducting control signals to an electrosurgical apparatus which delivers the electrical energy and the gas. A nozzle and electrode assembly fits within the end of the tubing.
