ABSTRACT:
A high-frequency snare for an endoscope has an electrically conductive control wire axially movably inserted in an electrically insulating sheath. A wire loop formed from an electrically conductive elastic wire is connected at the rear end thereof to the control wire. A distal end tip is attached to a bent portion at the distal end of the wire loop. The distal end tip has a pair of parallel through-holes. Two approximately parallel portions of the elastic wire bent in a U-shape at the bent portion of the wire loop are loosely passed through the through-holes, respectively, without being secured to the distal end tip.
