Wire knot delivery device

1. A wire knot delivery device for delivering and maintaining a knot of a medical wire, comprising:

a first body comprising a first plate part, and a first through hole passing through the first plate part;

a second body parallel to the first body and comprising a second plate part, and a second through hole passing through the second plate part, wherein the second body moves relative to the first body;

a first loop connected to the first body and caught by a side of the knot;

a second loop connected to the second body and caught by another side of the knot;

a coupling member head having a size that prevents the coupling member head from passing through the second through hole;

a coupling member rod extending from the coupling member head and inserted in the second through hole and the first through hole; and

a coupling member threaded to an end part of the coupling member rod opposite to the coupling member head,

wherein as the second body moves, a distance between the first loop and the second loop is adjusted.

2. The wire knot delivery device according to claim 1 , further comprising a catheter tube which guides a movement of the second body such that the second body slides relative to the first body.

3. The wire knot delivery device according to claim 1 , wherein the first loop is coupled to a first rear string routed through a first plate part of the first body; and

the wire knot delivery device further comprises a first adjustment part coupled to the first plate part and configured to wind the first rear string,

wherein the first adjustment part includes a first rotation member threaded to the first plate, and a first press member coupled to the first rotation member and configured to press the first rear string to a rotation shaft of the first rotation member.

4. The wire knot delivery device according to claim 1 , wherein the loop is coupled to a second rear string routed through a second plate part of the second body; and

the wire knot delivery device further comprises a second adjustment part coupled to the first plate part and configured to wind the second rear string,

wherein the second adjustment part includes a second rotation member threaded to the first plate, and a second press member coupled to the second rotation member and configured to press the second rear string to a rotation shaft of the second rotation member.

5. The wire knot delivery device according to claim 1 , wherein while the coupling member rod moves together with the second body, the coupling member rod is inserted in the second through hole, and

the first through hole elongated in a moving direction of the second body guides movement of the coupling member rod.

6. The wire knot delivery device according to claim 5 , wherein the coupling member moves together with the coupling member rod, and

the wire knot delivery device further comprises an auxiliary guide part with a groove into which the movement of the coupling member is inserted so that the coupling member is guided by the auxiliary guide part.

7. The wire knot delivery device according to claim 1 , further comprising a first handle part attached to the first body and having a hole.

8. The wire knot delivery device according to claim 1 , further comprising a second handle part attached to the second body and having a hole.

9. A surgical method for delivering a knot of a medical wire, comprising:

preparing a wire knot delivery device, which includes a first body comprising a first plate part, and a first through hole passing through the first plate part, a second body parallel to the first body and comprising a second plate part, and second through hole passing through the second plate part and wherein the second body moves relative to the first body, a first catching part comprising a first catching part loop and connected to the first body, a second catching part comprising a second catching part loop and connected to a side of the second body, a coupling member head having a size to be prevented from passing through the second through hole, a coupling member rod extending from the coupling member head and inserted in the second through hole and the first through hole, and a coupling member coupled as a nut to an end part of the coupling member rod opposite to the coupling member head wherein as the second body moves, a distance between the first catching part and the second catching part is adjusted (operation S 10 ),

passing the medical wire through the first catching part loop and the second catching part loop (operation S 20 );

forming the knot by forming the medical wire into a circular shape (operation S 30 );

moving the knot to a part to be medically treated in the body of a patient, by moving the wire knot delivery device in a first mode that the first catching part loop and the second catching part loop are spaced apart from each other (operation S 40 );

adjusting tension of the medical wire by pulling the medical wire (operation S 50 ); and

forming a second mode that the first catching part loop and the second catching part loop are adjacent to each other, and tightening the knot of the medical wire (operation S 60 ),

wherein the first catching part has a string shape extending from the first plate part and forming the first catching part loop by bending and returning to a side of the first plate part,

wherein the second catching part has a string shape extending from the second plate part and forming the second catching part loop by bending and returning to a side of the second plate part.

10. The surgical method according to claim 9 , further comprising cutting and removing an unnecessary part of the medical wire (operation S 70 ) after operation S 60 .

11. The surgical method according to claim 9 , further comprising completely removing the first catching part from the part to be medically treated, by cutting the first catching part at a point C 1 outside of the body of the patient and pulling the first catching part outside of the body of the patient (operation E 10 ) after operation S 60 .

12. The surgical method according to claim 9 , further comprising completely removing the second catching part from the part to be medically treated, by cutting the second catching part at a point C 2 outside of the body of the patient and pulling the second catching part outside of the body of the patient (operation E 20 ) after operation S 60 .
