Abstract
A double irrigating bipolar surgery forceps for reducing char buildup on working regions of the forceps. Each of the two forceps arms provides electrical current to the working regions and carries a fluid conduit for delivering irrigating fluid to the working region of the arm. The fluid conduits are, in a preferred form of the invention, carried on an outside surface of each arm and deliver irrigating fluid to an inside surface of each arm proximate to or within the working region. In a particularly preferred embodiment, an open channel is formed on the inside surface of each working region and in communication with the distal end of the arm's fluid conduit for improved delivery of irrigating fluid from the fluid conduit onto the working region and to the cautery site.
