Abstract: A clip device includes an arm portion including a plurality of arms that are biased to an open state; a pressing tube into which a proximal-end portion of the arm portion is accommodated and configured to be able to lock the arm portion in a closed state; an insertion portion connected to a proximal-end opening of the pressing tube at a distal end of the insertion portion; a power transmission member extending through the insertion portion; a link configured to detachably connect a distal-end portion of the power transmission member and a proximal-end portion of the arm portion; a first stopper configured to regulate the distal-end portion of the power transmission member from protruding from a distal-end opening of the pressing tube, and a switching portion configured to switch the clip device between a first state and a second state.

Abstract: A medical device, a clip unit, and a method for indwelling a clip unit. The medical device includes a treatment portion, an operation wire that can operate the treatment portion, and a link that can releasably connect the treatment portion and the operation wire. The link includes a hook that includes first and second deformation portions, and a base that can be releasably coupled to the hook. The first deformation portion is capable of being deformed by movement of the operation wire, and the second deformation portion is capable of being deformed by further movement of the operation portion after the first deformation portion is deformed.

Abstract: A treatment device includes an indwelling device including a treatment portion, and a tubular member including a proximal-end opening and in which a proximal-end portion of the treatment portion is disposed. The treatment device further includes an actuator including a connector releasably connected to a proximal-end portion of the treatment portion, and a power transmission member connected to the connector for moving the connector. The treatment portion can be fixed with respect to the tubular member when the power transmission member is retracted such that connector pulls the proximal-end portion of the treatment portion in a proximal direction to a predetermined position. The treatment device also includes a regulation portion for regulating a displacement of the connector in a direction separating from a longitudinal axis of the tubular member in the state in which the connector pulls the proximal-end portion towards the predetermined position.
