Abstract
A treatment instrument for an endoscope includes: a front end hood that is provided to a distal end of an inserting portion of the endoscope; a supporting member that is provided inside the front end hood; a treatment member that is rotatably supported by the supporting member; and an operating wire that is coupled to the treatment member and extended rearwardly from the front end hood. The treatment member is rotated about the supporting member by operating to extract and retract the operating wire at a base side of the endoscope.
Claims18
A treatment instrument for an endoscope, comprising:
- a front end hood that is provided to a distal end of an inserting portion of the endoscope;
- a supporting member that is provided inside the front end hood;
- a treatment member that is rotatably supported by the supporting member, the treatment member including a grabbing member, the grabbing member being rotatably supported by the supporting member at a rear side of the grabbing member;
- and
- an operating wire that is coupled to the treatment member and extends rearwardly from the front end hood,
- wherein the grabbing member is rotated about the supporting member at a vicinity of an opening of the front end hood by the extension and retraction of the operating wire, at a base side of the endoscope;
- wherein the grabbing member is provided with a spring characteristic and is elastically flexed by grabbing a foreign matter.
A treatment instrument for an endoscope, comprising:
- a front end hood that is provided to a distal end of an inserting portion of the endoscope;
- a supporting member that is provided inside the front end hood;
- a treatment member that is rotatably supported by the supporting member, the treatment member including a pair of beak-shaped treatment members, the pair of beak-shaped treatment members being rotatably supported by the supporting member;
- and
- an operating wire that is coupled to the treatment member and extends rearwardly from the front end hood, the operating wire comprising operating wires that are coupled to rear sides of the pair of beak-shaped treatment members, respectively;
- wherein the pair of beak-shaped treatment members are opened and closed by rotation about the supporting member in a beak-like manner at a vicinity of an opening of the front end hood by the extension and retraction of the operating wires at the base side of the endoscope, and
- wherein the front end hood is configured with a notch for eliminating interference of the opened pair of beak-shaped treatment members with the front end hood.
