Abstract:
1. An electrosurgical system comprising: a grasper having a first jaw and a second jaw that are movable relative to each other between an open condition and a closed condition so as to be capable of grasping tissue, the grasper including a first electrode disposed on the first jaw and that is attachable to a first output of an energy supply, the grasper including a third electrode disposed on the second jaw and that is selectively attachable to a second output of the energy supply, the third electrode is electrically isolated from the first electrode; a snare having a second electrode that is selectively attachable to the second output of the energy supply; and switching circuitry that selectively couples the second electrode or the third electrode to the second output of the energy supply, the switching circuitry being switchable between at least first and second positions, (i) the switching circuitry coupling the second electrode to the second output of the energy supply when in the first position to enable the grasper and the snare to operate as a bipolar electrosurgical system, and (ii) the switching circuitry disconnecting the second electrode from the second output of the energy supply when in the second position and coupling the second output of the energy supply to the third electrode when in the second position so that the grasper operates as a bipolar grasper when the switching circuitry is in the second position.
