Abstract:
A manipulating part of an endoscopic treatment tool, comprising:a shaft member having a first finger retaining member and an elongated slit formed along the length of said shaft member;a second finger retaining member slidably mounted to said shaft member so that a sliding movement of said second finger retaining member along said shaft member drives a distal end operating part remote from said manipulating part; anda stopper movably provided on said shaft member, and fixed at an arbitrary position on said shaft member and along the length of said slit, said stopper restricting a length of said sliding movement of said second finger retaining member;wherein said shaft member is elastically deformed along the length of said slit to permit said movement of said stopper relative to said shaft member, and a deformation restricting member is connected to said second finger retaining member in said elongated slit to inhibit said elastic deformation of said shaft member when said second finger retaining member is located close to said stopper.
