Abstract

A removable handswitch and electrode assembly for use with a forceps having opposing end effectors and a handle for effecting relative movement of the end effectors with respect to one another includes a housing having at least one portion which removably engages at least a portion of a mechanical forceps and a handswitch assembly disposed on the housing. A pair of electrodes is included which removably engage a distal end of the mechanical forceps such that the electrodes reside in opposing relation to one another. At least one electrode is adapted to connect to an electrosurgical generator through the handswitch assembly. At least one stop member is operatively associated with the electrodes and controls the distance between the opposing electrodes to affect a tissue seal.
