ABSTRACT:
A disposable bipolar electrosurgical probe which can be readily applied to the tissue to be treated, then discarded. The probe comprises an elongated substrate member having a peripheral surface of dielectric material and a longitudinal axis extending between a working end and an attachment end. At least a pair of electrically isolated electrodes extend continuously on the peripheral surface of the substrate member between an active region at the working end and an electrical terminal region at the attachment end for quick connection and/or disconnection, respectively, to opposite poles of an RF generator. A handle with a quick disconnect mechanism is provided to physically support the probe and enable it to be selectively energized. The probes can be of a fail safe construction so as to assure that only a proper probe can be used for a desired treatment.
