Patent ID: 8828026

Claim:
A tissue fastening tool indwelling apparatus comprising: a long axis member in which an opening is formed at a distal end side thereof, the long axis member being provided with a lumen having a longitudinal axis and being communicated with the opening; a stylet inserted into the lumen so as to freely move along a longitudinal axis direction in the lumen and to be rotatable around the longitudinal axis direction; an operating section that moves the stylet to the longitudinal axis direction in the lumen and rotates the stylet around the longitudinal axis direction in the lumen; a connecting section that is formed at a distal end of the stylet, is detachably connected to a tissue fastening tool, which is configured such that a wire wound in a coil form is arranged while being stretched, and moves along and rotates around the longitudinal axis direction in the lumen with the stylet and the tissue fastening tool depending on an operation of the operating section, and a rotating mechanism that guides the stylet to a direction which moves the stylet toward the distal end of the long axis member relative to the long axis member and that guides the stylet in a direction which rotates the stylet around the longitudinal axis depending on an operation of the operating section, wherein the rotating mechanism is configured to rotate the stylet in a wound direction of the tissue fastening tool in which the tissue fastening tool restores to the coil form so that compressing force of the tissue fastening tool acts in an axial direction of the tissue fastening tool when the tissue fastening tool is protruded from the long axis member.
