A suturing device that is inserted into the body, releasing the anchor of the elongated locked to the tissue, the elongate member distal end adapted to be introduced into the tissue from the proximal end of the proximal side extends to a flexible, and at the distal end of the elongate member has a pierceable sharp end tissue tip, as well as a plurality of accommodating the anchor, the side holes of the anchor can pass is provided inside a pusher having a distal end abuts against the needle, the anchor is housed in the needle inside is disposed so as to be movable in the axial direction of the member in said elongated, provided on the pusher or the needle, with the pusher I was suture instrument with a extrusion control unit for changing the direction toward the side hole from the longitudinal direction of the needle movement direction of the anchor is moved to the forming position of the side hole.体内に挿入され、組織に係止される細長のアンカーを放出する縫合器であって、手元側の近位端から組織に導入される遠位端まで延び、可撓性を有する細長部材と、前記細長部材の遠位端に設けられ、先端に組織を穿通可能な鋭利な端部を有し、内部に前記アンカーを複数収容可能であると共に、前記アンカーが通過可能な側孔が設けられた針と、前記針内に収容された前記アンカーに遠位端が当接し、前記細長部材内を軸方向に移動可能に配設されたプッシャと、前記針又は前記プッシャに設けられ、前記プッシャで前記側孔の形成位置まで移動させられた前記アンカーの移動方向を前記針の長さ方向から前記側孔に向かう方向に変化させる押し出し制御部と、を有する縫合器とした。
