摘要:
Embodiments of this invention relate to endoscopic and laparoscopic surgical instruments. More specifically, embodiments of this invention relate to an open loop snare device including a means for securely closing the loop. In some embodiments, a snare device comprises a snare wire and a capture mechanism wherein, when the snare wire is advanced, the snare wire extends from a distal portion of the device along an arcuate path curving back toward the capture mechanism such that, after the snare wire is advanced, activation of the capture mechanism captures the snare wire, creating a formed loop around a target tissue. Retraction of at least one of the snare wire and capture mechanism contracts the formed loop, resecting the target tissue.
