Claims
- 1. In a surgical snare of the type including a sheath and a wire assembly slidably mounted within the sheath, the wire assembly being moved within the sheath as a result of its being manipulated by a user at a neat end thereof, the wire assembly being formed into an electrically conductive flexible wire loop at a distal end thereof, the loop being retractable substantially entirely into the sheath by virtue of its flexibility, the improvement comprising means responsive to the manipulation of the near end by the user for causing said loop to become discontinuous, whereby the snare may be removed from a patient when the loop becomes caught on a polyp.
- 2. The surgical snare of claim 1, wherein said means for causing said loop to become discontinuous, comprises a frangible region on said loop, said loop being opened by supplying sufficient force to said wire assembly when it is caught on a polyp to cause said frangible region to break.
