    Abstract: An endoscope treatment tool includes: a cylindrical distal-end member to be attached to a distal end of an endoscope; a grasping tool that is provided at an outer side surface of the endoscope along a longitudinal axis of the endoscope, that grasps biological tissue, and that is movable in a first direction perpendicular to the longitudinal axis in a state in which the biological tissue is grasped; an electrode that is disposed so as to protrude forward with respect to a distal end of the distal-end member; and an electrode driving portion that is configured to move the electrode in the first direction.

    Abstract: An endoscope treatment tool includes: a cylindrical cap attached to an outer side of a distal-end section of an endoscope and having first and second radial directions intersecting each other; a treatment tool supported at an outer side of the cap in the first radial direction to be movable in the longitudinal direction; and a linear flexible coupling member coupling the treatment tool with the cap such that the grasper reaches a position where the grasper protrudes from a distal end of the cap. A swing section of the coupling member couples the cap with the treatment tool to allow relative movement in the second radial direction, and, in response to pressed forward in the longitudinal direction by the treatment tool, swings about a swing axis extending in the second radial direction while generating a tensile force and bending the treatment tool inward in the first radial direction.

    Abstract: An endoscope cap includes: a hood portion attached to a distal end portion of an endoscope; a cap portion connected to a distal end of the hood portion, having an abutting surface against which the endoscope is abutted in a state of the endoscope being inserted into the hood portion, and protruding from the distal end of the hood portion; a channel tube into which an elongated device is inserted; and a coupling member for coupling the device with the hood portion, the member being supported by the hood portion and extending along the hood portion. The hood portion has a pair of support holes into which the member is inserted. The member is pivotable with respect to the hood portion, with the individual support holes serving as fulcrums. The holes are formed at positions closer to a proximal end of the hood portion than the abutting surface is.

    Abstract: An endoscope clip can include an arm portion that can move into the following configurations: a closed configuration, a first open configuration in which the pair of arms are separated at a first distance, and a second open configuration in which the pair of arms are separated at a second distance larger than the first distance. The endoscope clip can also include an operation wire and a restriction portion configured to restrict movement of the operation wire to fix the arm portion in one of the possible configurations.

    Abstract: Provided is an endoscope clip. The clip includes an arm having a first arm and a second arm, the arm configured to be transitioned between a first configuration in which the first arm and the second arm are separated from each other by a first amount and a second configuration in which the first arm and the second arm are separated from each other by a second amount larger than the first amount. The clip includes a slider to operate the arm to be transitioned between the configurations, and a limiter configured to restrict movement of the slider so as to restrict the transition of the arm from one configuration to another of the configurations.
