The tissue fastener placement device system includes a sheath formed with a lumen, a needle tube formed in a cylindrical shape, and disposed inside the sheath so as to be able to protrude and retract from the distal end of the lumen, and a state in which the needle tube is extended inside the needle tube. A tissue clamp having a coil area that can be restored to a coil shape having the same winding diameter outside the needle tube, a stylet connected to the end of the tissue clamp inside the needle tube, and a tissue clamp. An operation unit for operating the stylet so as to advance the tool while rotating the tool, and for rotating the sheath in one direction around the longitudinal axis when the stylet is advanced, wherein the distal end of the needle tube is more proximal than the distal end of the sheath. In the state located on the end side, the operating unit moves forward while rotating the tissue fastener and rotates the sheath in one direction, the tissue fastener projects from the sheath by a length corresponding to one turn of the coil area. Do The sheath is configured to rotate by a rotation amount of less than one rotation, a coil region projecting from the sheath is biased so that a greater than the winding diameter size.組織締付具留置装置システムは、ルーメンが形成されたシースと、筒状に形成され、ルーメンの先端から突没自在にシース内に配置された針管と、針管の内部に引き延ばされた状態で配置され、針管の外部で同一巻き径のコイル状に復元可能なコイル領域を有する組織締付具と、針管の内部で組織締付具の端部に接続されたスタイレットと、組織締付具を回転させながら前進させるようにスタイレットを動作させると共に、スタイレットを前進させる際にシースを長手軸周りの一方向に回転させる操作部とを備え、針管の先端がシースの先端よりも基端側に位置する状態において、操作部は、組織締付具を回転させながら前進させると共にシースを一方向に回転させるとき、組織締付具がシースからコイル領域の一巻き分の長さだけ突出する間にシースが１回転未満の回転量だけ回転するように構成され、シースから突出したコイル領域が、巻き径よりも大きい径となるように付勢される。
