View Patent ↗A medical apparatus including a bar with a first attachment loop, a second attachment and a plurality of hooks, wherein the medical apparatus is an arch bar.
1. A surgical method comprising the steps of:
bending a first plate to the contour of a mandible;
inserting a first screw through a first hole formed with the first plate and into the mandible;
inserting a second screw through a second hole formed with first plate and into the mandible;
bending a second plate to the contour of a maxilla;
inserting a third screw through a third hole formed with the second plate and into the maxilla;
inserting a fourth screw through a fourth hole formed with the second plate and into the maxilla; and
attaching a first wire to the first plate and the second plate, the wire preventing movement of the mandible away from the maxilla.
2. The surgical method of claim 1 , wherein the attaching step includes attaching the first wire to a first hook monolithically formed with the first plate and a second hook monolithically formed with second plate.
3. The surgical method of claim 2 , further comprising the step of attaching a second wire to a third hook monolithically formed with the first plate and a fourth hook monolithically formed with the second plate.
4. The surgical method of claim 3 , wherein the first and second wires cross each other.
5. The surgical method of claim 1 , further comprising the step of bending a first stem connecting the first hole to the first plate.
6. The surgical method of claim 3 , further comprising the step of bending a second stem connecting the second hole to the first plate.
7. A surgical method comprising the steps of:
bending a first plate to the contour of a mandible;
inserting a first screw through a first hole formed with the first plate and into the mandible;
inserting a second screw through a second hole formed with first plate and into the mandible;
bending a second plate to the contour of a maxilla;
inserting a third screw through a third hole formed with the second plate and into the maxilla;
inserting a fourth screw through a fourth hole formed with the second plate and into the maxilla; and
attaching a first wire to a first hook monolithically formed with the first plate and a second hook monolithically formed with the second plate, the wire preventing movement of the mandible away from the maxilla.
8. The surgical method of claim 7 , further comprising the step of attaching a second wire to a third hook monolithically formed with the first plate and a fourth hook monolithically formed with the second plate.
9. The surgical method of claim 8 , wherein the first and second wires cross each other.
10. The surgical method of claim 7 , further comprising the step of bending a first stem connecting the first hole to the first plate.
11. The surgical method of claim 9 , further comprising the step of bending a second stem connecting the second hole to the first plate.
12. A surgical method comprising the steps of:
bending a first plate to the contour of a mandible;
determining a first position in the mandible for a first screw;
inserting the first screw through the first plate into the first position in the mandible;
determining a second position in the mandible for a second screw;
inserting the second screw through the first plate into the second position in the mandible;
bending a second plate to the contour of a maxilla;
determining a third position in the maxilla for a third screw;
inserting the third screw through the second plate into the third position in the maxilla;
determining a fourth position in the maxilla for a fourth screw;
inserting the fourth screw through the second plate into the fourth position in the maxilla;
attaching a first wire to the first plate and the second plate, the wire preventing movement of the mandible away from the maxilla.
13. The surgical method of claim 12 , wherein the attaching step includes attaching the first wire to a first hook monolithically formed with the first plate and a second hook monolithically formed with second plate.
14. The surgical method of claim 13 , further comprising the step of attaching a second wire to a third hook monolithically formed with the first plate and a fourth hook monolithically formed with the second plate.
15. The surgical method of claim 14 , wherein the first and second wires cross each other.
16. The surgical method of claim 12 , further comprising the step of bending a first stem connecting a first hole to the first plate, the bending of the first stem based upon the determining of the first position and the inserting of the first screw step including placing the first screw through the first hole.
17. The surgical method of claim 16 , further comprising the step of bending a second stem connecting a second hole to the first plate, the bending of the second stem based upon the determining of the second position and the inserting of the second screw step including placing the second screw through the second hole.
18. The surgical method of claim 17 , further comprising the step of bending a third stem connecting a third hole to the second plate, the bending of the third stem based upon the determining of the third position and the inserting of the third screw step including placing the third screw through the third hole.
19. The surgical method of claim 18 , further comprising the step of bending a fourth stem connecting a fourth hole to the second plate, the bending of the fourth stem based upon the determining of the fourth position and the inserting of the fourth screw step including placing the fourth screw through the fourth hole.
