Patent ID: 8702753

Claim:
A method for suturing a perforation formed in a hollow organ by a suture thread, comprising the steps of: causing a first end portion and a second end portion of the suture thread to penetrate through tissues on both sides of the perforation in a same direction as each other, each of the first end portion and the second end portion including an anchor, the anchor having an outer side surface which has a longitudinal shape and connects a distal end and a proximal end of the anchor, each of the first end portion and the second end portion being connected to the outer side surface and being formed in a T-shape; forming a loop of the suture thread by connecting the anchors provided at the first end and the second end portions of the suture thread to each other outside of the tissues such that the outer side surfaces of the anchors are parallel to each other after the first end and the second end portions of the suture thread penetrate through the tissues on the both sides of the perforation, wherein a side opposite to the outer side surface connected to the first end portion and a side opposite to the outer side surface connected to the second end portion are connected to each other, the first end portion and the second end portion being disposed so as to face each other, the suture thread extending from each of the anchors toward an outside of the perforation; displacing a stopper, which the suture thread penetrates through, relative to the suture thread so as to be close to a side of the first and second end portions of the suture thread after connecting the first end and the second end portions of the suture thread to each other; moving the tissues on the both sides of the perforation in directions of being close to each other and closing the perforation, by pulling the suture thread so as to be close to an opposite side of the side of the end portions such that a diameter of the loop decreases; and maintaining a tensional force of the suture thread by the stopper holding the suture thread.
