Abstract: A treatment device has an arm member having a plurality of arms to have an open state and a closed state; a wire having a distal end connected to the arm member and the distal end is attachable and detachable to the arm member; a sheath through which the wire is inserted; an operator connected to a proximal end of the sheath; a slider connected to the wire and attached to the operator to be slidable toward a distal end or a proximal end of the operator, wherein the slider makes the plurality of arms to be in the closed state when the slider is disposed in a first range, and the slider makes the plurality of arms to be in the open state when the slider is disposed in a second range; and a slider restriction mechanism provided between the distal end of the operator and the slider.

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.
