Abstract

A method for suturing a perforation formed in a hollow organ comprises the steps of: causing plural end portions of the suture thread to puncture a tissue around the perforation in the same direction as each other; connecting the end portions of the suture thread to each other; and tightening up the suture thread after connecting the end portions of the suture thread with each other.

Claims

1. A method for suturing a perforation formed in a hollow organ by a suture thread, comprising the steps of:

causing plural end portions of the suture thread to puncture a tissue around the perforation in the same direction as each other;

connecting the end portions of the suture thread to each other; and

tightening up the suture thread after connecting the end portions of the suture thread with each other.

2. The method according to claim 1, wherein in the step of connecting the end portions of the suture thread to each other, anchors provided at each of the end portions of the suture thread are attached to each other, and the end portions of the suture thread are connected to each other via the anchors.

3. A suture instrument for suturing a perforation formed in a luminal tissue, comprising:

a suture thread for penetrating the tissue around the perforation;

a first connection member provided at a first end portion of the suture thread; and

a second connection member provided at a second end portion of the suture thread and connectable to the first connection member.

4. The suture instrument according to claim 3, wherein the first connection member has at least one polarized portion, and the second connection member has a member which is attached to the first connection member due to a magnetic force of the first connection member.

5. The suture instrument according to claim 3, wherein the first connection member has a hole, and the tip of the second connection member is bent so as to be able to be inserted into the hole.
