Abstract
Abstract The present invention provides a disposable electrosurgical device which is useful in performing laparoscopic surgical procedures. This electrosurgical device has suction and irrigation capabilities in which the application of electrosurgical current, the application of suction, and the transmission of irrigation fluid, to a surgical site, can be conveniently regulated through control mechanisms contained within a surgical handpiece. The mechanisms which regulate the electrosurgical current, the suction, and the irrigation can be conveniently actuated independently with one hand at a single location on the surgical handpiece. A disposable rotatable combined electrosurgical-suction-irrigation probe releasably attaches to the distal end of the surgical handpiece. This probe is an electrically conductive fluid conduit which forms an electrical and fluid connection to the surgical handpiece. It provides an electrical and fluid passageway to an electrocauterizing tip which applies the therapeutic electrosurgical current.
