Suturing method for penetrating hole
A suturing method for a penetrating hole formed in a luminal organ using a suture material to close the penetrating hole according to the present invention includes the steps of inserting a needle at a position that is removed from the open edge of the penetrating hole by a distance that is less than the thickness of the wall of the luminal organ and passing the needle through the wall; sending out from the needle an anchor affixed to the end of the suture material; placing the anchor in place by pulling the needle through the wall and passing the suture material through the wall; and tightening the suture material after passing the suture material in the same direction through the wall at multiple sites interposing the penetrating hole.
1. A suturing method for a penetrating hole formed in a stomach using a suture material passing through a hole of a stopper to close the penetrating hole comprising the steps of:
inserting a needle at insertion positions that are separated from an open edge of said penetrating hole by a distance that is less than a thickness of a wall of said stomach from a mucosa side of said stomach, and passing said needle through said wall;
sending out from said needle an anchor affixed to an end of the suture material;
placing said anchor in place by pulling said needle through said wall and passing said suture material through said wall;
adhering muscular tunics of said stomach together by tightening said suture material so that said stopper and said stomach contact with each other and all of the insertion positions and the hole of said stopper approximately coincide with each other by advancing said stopper relative to said suture material so that a distance between said stopper and said anchor is decreased after passing said suture material in the same direction through said wall at multiple sites interposing said penetrating hole.
2. A suturing method for a penetrating hole according to claim 1 further comprising the step of tightening said suture material further so that the tissue near the insertion position is compressed and partially crushed.
3. A suturing method for a penetrating hole according to claim 1 , wherein said stopper only moves in a direction in which the distance between said stopper and said anchor is decreased.
4. A suturing method for a penetrating hole according to claim 1 further comprising the step of falling said stopper into the mucosa side of said stomach.
5. A suturing method for a penetrating hole according to claim 1 , wherein the step of adhering the muscular tunics of said stomach is conducted so that said wall from the open edge of said penetrating hole to each of the insertion positions is bent toward a side of an abdominal cavity of said stomach.
6. A suturing method for a penetrating hole according to claim 1 , wherein said stopper and the mucosa side of said stomach contact with each other by advancing said stopper.
7. A suturing method for a penetrating hole according to claim 1 , wherein a plate member of said stopper and said stomach contact with each other by advancing said stopper, the plate member having the hole of said stopper.
8. A suturing method for a penetrating hole according to claim 7 , wherein substantially all of a surface of the plate member and said stomach contact with each other by advancing said stopper.
