Abstract: A tissue-fastening tool indwelling device includes: a sheath; a needle tube having a needle tip and disposed to be retractable from a distal end of a lumen of the sheath; a tissue-fastening tool having a restoring force to a curved shape with distal and proximal end side regions and disposed inside the needle tube in a stretched state; and a stylet coupled to a proximal end portion of the tissue-fastening tool in the needle tube. The stylet has a first state in which the stylet is advanced straight with respect to the needle tube and the sheath until the entire distal end side region of the tissue-fastening tool protrudes from the needle tube, and a second state in which the stylet is advanced while being rotated until a proximal end of the proximal end side region of the tissue-fastening tool protrudes from the needle tube.

Abstract: An endoscopic treatment tool includes a sheath having a lumen, an elongated shaft inserted into the lumen and having an insertion passage, a stylet disposed in the insertion passage, an implant connected to the stylet, and a manipulation part main body provided on the sheath, a slider advanceable and retractable in an axial direction relative to the manipulation part main body, and a cam tube retracting while rotating in accordance with manipulation of the slider and having a spiral guide passage. A proximal end portion of the stylet has a projection engaged with the guide passage such that a force retracting the stylet is applied to the stylet by the cam tube retracting while rotating. The projection is slidable on the guide passage such that the stylet is advanceable relative to the elongated shaft against the force.

Abstract: A tissue-fastening tool indwelling system includes: a sheath; a needle tube disposed in the sheath; a tissue-fastening tool including a wire having a coil region disposable in the needle tube in a stretched state and restorable to a coil shape with the same winding diameter outside the needle tube; a stylet connected to the wire; and a manipulation part for manipulating the stylet to advance the wire and rotate the sheath in a first direction. In a state where a distal end of the needle tube is proximal of the distal end of the sheath, the manipulation part is designed to operate such that the wire is delivered from the sheath by a length of one winding of the coil region per rotation of the sheath by less than one turn, and the protruding coil region biased to have a diameter larger than the winding diameter.

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.
