摘要：
Embodiments of this invention relate to endoscopic and laparoscopic surgical instruments. More specifically, embodiments of this invention relate to an open loop polypectomy system including a means for securely closing the loop. In some embodiments, the open loop polypectomy system 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 open loop polypectomy system along a path passing through the capture mechanism. After the snare wire has advanced through the plane of the capture mechanism, retraction of the capture mechanism secures 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.
