Abstract
An endoscope treatment tool includes: a cap defining a longitudinal axis and a proximal-end opening for insertion of a distal end section of an endoscope to detachably attach the cap to the endoscope; a treatment tool extending longitudinally along an outside of the cap and having a distal end configured for tissue manipulation; and a coupling member extending between the cap and the treatment tool to movably couple the treatment tool to the cap, the coupling member having high flexibility.
Claims22
A endoscopic tool comprising:
- a cap configured to be attached to a distal end of a flexible tubular member, the cap having a channel extending longitudinally to accept the distal end of the flexible tubular member;
- a guide hole having an opening on an outer peripheral surface of the cap;
- and
- a filament extending through the guide hole such that the filament and the outer peripheral surface of the cap contact each other.
A endoscopic tool comprising:
- a cap configured to be attached to a distal end of a flexible tubular member, the cap having a channel extending longitudinally to accept the distal end of the flexible tubular member;
- a support portion disposed on the outside of the cap;
- and
- a filament configured to swing around the support portion.
A system comprising:
- a flexible tubular member;
- a cap configured to be attached to a distal end of the flexible tubular member, the cap having a channel extending longitudinally to accept the distal end of the flexible tubular member;
- a guide hole having an opening on an outer peripheral surface of the cap;
- and
- a filament extending through the guide hole such that the filament and the outer peripheral surface of the cap contact each other.
