Patent ID: 7998150

Claim:
A suturing device that sutures a tissue using a suture unit having a suture thread with both ends fitted to a first anchor and a second anchor, respectively, the suturing device comprising: a suture unit having a suture thread with both ends fitted to a first anchor and a second anchor; a hollow tip member receiving the first and second anchors; a wire having a front end inserted through the hollow tip member so that the first and second anchors can be released out from the hollow tip member; a flexible tube having a distal end integrally connected at a proximal end of the hollow tip member, through which the wire is inserted so as to freely move forward and backward in the axial direction of the flexible tube; a parallel member inserted through the flexible tube so as to freely move forward and backward in the axial direction of the flexible tube along with the wire; a relative position holding member fitted to the wire so as to hold constant a relative positional relationship between the wire and the parallel member, wherein the relative position holding member has an outer diameter that is larger than an outer diameter of the wire; a forward movement restricting member provided on the distal end of the flexible tube or the proximal end of the hollow tip member so as to restrict a forward movement of the parallel member; and an operating portion provided at a proximal end of the wire and the parallel member so as to operate the wire and the parallel member, wherein in a state in which the relative positional relationship between the wire and the parallel member is held constant by the relative position holding member, when the wire is moved in the forward direction until the forward movement of the parallel member is restricted by the forward movement restricting member, only the first anchor is released from the hollow tip member by the movement of the wire, and wherein at least one of the hollow tip member, the forward movement restricting member, and the flexible tube has a communication portion on an outer peripheral surface thereof so as to communicate with an internal cavity, and a middle portion of the suture unit is inserted into the communication portion and is tied to the wire.
