ELECTROSURGICAL MODE CONVERSION SYSTEM

摘要

This invention is a surgical system that applies electrical energy to obtain predetermined surgical effects while improving the control of the application of energy that is supplied by electro-surgical generators. In one embodiment, a surgical assembly (300) interfaces with, and receives power from an electro-surgical generator for executing a first electro-surgical procedure. This surgical assembly (300) may employ a shunt circuit (16) between its power (7), and return (11) lines for providing in effect a voltage limitation; and/or to allow a constant power generator to execute an at least substantially constant voltage electro-surgical technique. The electro-surgical assembly (300) may also include a return coupler (6) for directing energy from the patient back to the electro-surgical generator, which in turn may include a dielectric material which interfaces with the patient, and which at least initially conveys the return energy via one or more electric fields versus conduction.
