Abstract: An injection needle for an endoscope includes: an outer and inner sheath; a needle tube; a stopper; an engaging contact portion integrally formed of the same material as the outer sheath, protrudes to an inner side in a radial direction relative to an inner circumferential surface of the outer sheath; and an operating member. A movable range of the operating member in a straight state is made up of a first range and a second range. A length of the second range is greater than a value of a difference between an inner diameter of the outer sheath and an outer diameter of the inner sheath, and a thickness of the engaging contact portion in the direction of the longitudinal axis is greater than a thickness of the inner sheath in a radial direction and a thickness of the outer sheath in the radial direction.

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.

Abstract: An endoscopic surgical device that includes: a sheath; a manipulator; a manipulation wire; a clip body having a pair of arms, connected to a distal end of the manipulation wire, and configured to be capable of advancing and retracting in accordance with manipulation of the manipulator along with a longitudinal axis of the manipulation wire; a holding tube into which a proximal portion of the clip body is inserted to be capable of advancing and retracting; and a biasing member configured to hold a position of the manipulation wire at an initial position. The clip body is nonrotatable around the longitudinal axis at the initial position. When the manipulation wire is advanced a prescribed amount against a biasing force of the biasing member, the clip body is rotatable around the longitudinal axis, and is allowed adjustment of an opening-closing direction of the pair of arms.
