Electromechanical polyp snare

Abstract

An electrosurgical device for use with an electrosurgical generator to remove polyps from the gastrointestinal tract comprising a hand piece including a body or housing having an operator handle and a snare support attached thereto, a snare guide including a snare channel formed therethrough to slidably receive at least a portion of a polyp snare including a snare loop therein and a snare positioning assembly coupled to the polyp snare to selectively move the polyp snare between an extended portion and a retracted position attached to the snare support and a remote switch assembly coupled between the electrosurgical generator and the snare positioning assembly to selectively energize the electrosurgical generator, to selectively operate the snare positioning assembly to move the polyp snare from the retracted position to the extended position such that the snare loop encircles a polyp to be removed from the gastrointestinal tract and to selectively supply energy from the electrosurgical generator to the snare loop to cut the encircled polyp from the gastrointestinal tract and to move the polyp snare from the extended position to the retracted position once the polyp is cut.
