Abstract:
A surgical instrument, comprising:a body having proximal and distal parts, said distal part including a passageway extending axially therethrough, said passageway having first and second ports; with slots; a snare electrode adapted to telescope in said passageway, said distal part having an outward surface electrically insulated from said snare electrode; said snare electrode including first and second portions, said second portion being extendable from said second port for forming a loop sized to be placed over tissue to be removed from a patient; a spool rotatably supported in said proximal part with port, said first portion of said snare electrode being windable about said spool, wherein a rotation of said spool in a winding direction causes retraction of said first portion of said snare electrode from said first port, thereby closing said loop to engage said tissue; and an electrical connector connecting said snare electrode to be coupled to an electrical source, wherein an electrical current is passed from said electrical source to said loop to cauterize said tissue.
