TREATMENT TOOL FOR ENDOSCOPE OF TIP LOOP TYPE

摘要

PROBLEM TO BE SOLVED: To provide a treating tool for an endoscope of a tip loop type which easily forms an elastic wire to expand symmetrically, easily catch a desired matter by reducing the length of a part projecting to a tip side from the tip part of a loop and keeps the shape of the elastic wire at the time of expanding without distortion. SOLUTION: Concerning parts between first bending parts 11 formed in the neighborhood of the tip binding part of elastic wires 10 and second bending parts 12 positioned at the front tip parts of the outer edges of the loop when the wires 10 expand in the shape of a loop, parts close to the first bending parts 11 are formed to project inward and parts close to the second bending parts 12 are formed in a smoothly curved state projecting outward.
