Abstract: A treatment device includes: an operating section; an elongated insertion section connected to the operating section; a pair of clamp members provided at the distal end of the insertion section so as to be openable and closable relative to each other; a movable member that is moved so as to push staples relative to tissue sandwiched between the clamp members; and a coil member that is arranged so as to pass through the insertion section in the longitudinal direction and that transmits a pressing force from the operating section to the movable member.

Abstract: A suture securing instrument can include a cylindrical body that has an inner circumferential surface, and a securing portion configured to secure a suture. The securing portion can include an outer circumferential surface supported by the inner circumferential surface of the cylindrical body by moving along a longitudinal axis relative to the cylindrical body, and a holding portion configured to hold the suture between the cylindrical body and the securing portion. The holding portion can also include a groove for the suture.

Abstract: A gastrointestinal-tract constricting method includes, while observing the gastrointestinal tract by inserting an endoscope into the gastrointestinal tract, forming a spreading block that blocks infiltration of a substance, which damages a mucosa basal layer of the gastrointestinal tract, into the muscular layer underlying the mucosa basal layer, the spreading block being formed along a circumferential direction of the gastrointestinal tract and between the mucosa basal layer and the muscular layer; and supplying the substance along the circumferential direction of the gastrointestinal tract and to a surface of the mucosa that lies within a region that overlaps an inner side of the gastrointestinal tract with respect to the spreading block out of the entire circumference of the gastrointestinal tract in a transverse section of the gastrointestinal tract.

Abstract: A tissue pressing tool includes: a shaft that extends in one direction; a tissue pressing part that is a rod-like or belt-like member having a rigidity enough to hold a shape thereof even when pressed against a tissue; and a passive bending part that is arranged between the tissue pressing part and the shaft so that the tissue pressing part is capable of bending in all direction around an axis line of the shaft so as to keep an inverted state of the tissue by the tissue pressing part pressing the tissue linearly

Abstract: A needle holder for holding a curved needle to which a suture thread is connected. The needle holder includes a flexible tube; and a grasper provided at a distal end of the flexible tube. The grasper includes a first jaw having a groove, and a protrusion at a distal end portion of the first jaw; and a second jaw movably connected to the first jaw. The grasper can hold the curved needle between the second jaw and the protrusion of the first jaw, and can hold a part of the suture thread between a surface of the groove and the second jaw such that another part of the suture thread passes through a gap formed between another surface of the groove and the second jaw. The protrusion has a hook surface for hooking the suture thread extending outside the groove.

Abstract: A locking member of a suture locking device includes a loop portion formed in an a-shape when viewed from a width direction, and a pair of extensions extending from the loop portion towards a distal side, and an intersection portion in which the pair of extensions intersect is formed at a distal end of the loop portion. The loop portion is inserted into the hollow portion from the distal side with the thread being inserted through an inner space of loop portion, and the thread is pulled from a proximal side towards the intersection portion in the inner space of the loop portion so that the thread is locked to the loop portion.

Abstract: The first fixing member and the second fixing member are arranged such that the first clamping surface and the second clamping surface face each other in an axis line direction of the insertion portion. When the manipulation portion is manipulated and the insertion portion and manipulation member is rotated relatively, the first clamping surface and the second clamping surface are configured to approach by screw-fitting with the second fixing member and the first fixing member. When a predetermined manipulation is performed to the manipulation portion, a coupling between the manipulation member and the other is configured to be released.
