Surgical methods of universal osteotomy device
The present invention provides a surgical method of universal osteotomy device comprises the steps of: placing a first body component and a second body component on the surface of a bone; engaging an engaging member with a connecting member; inserting at least one aiming bone pin in at least one aiming hole to confirm the cutting direction; cutting along a guide slot to produce an osteotomy; spreading said osteotomy; placing a bone plate to maintain the osteotomy; wherein the surface of the first body component and the surface of the second body component have an average curvature of bone surface or a uniform curvature.
1. A surgical method of universal osteotomy device comprising the steps of:
placing a first body component and a second body component on a surface of a bone;
engaging an engaging member with a connecting member;
inserting at least one aiming bone pin in at least one aiming hole to confirm a cutting direction;
cutting along a guide slot to produce an osteotomy;
spreading said osteotomy;
placing a bone plate to maintain said osteotomy;
wherein a surface of said first body component and a surface of said second body component have an average curvature of bone surface or a uniform curvature.
2. The surgical method of universal osteotomy device of claim 1 , wherein said first body component has an upper guide edge; said second body component has a lower guide edge disposed below said upper guide edge.
3. The surgical method of universal osteotomy device of claim 2 , wherein said guide slot is formed between said upper guide edge and said lower guide edge; said connecting member is disposed in said guide slot.
4. The surgical method of universal osteotomy device of claim 3 , wherein said engaging member and said aiming hole are disposed on an extracorporeal alignment component.
5. The surgical method of universal osteotomy device of claim 4 , wherein the step of inserting said aiming bone pin in said aiming hole comprises:
inserting an angle fixation bone pin in an angle fixation hole to maintain an angle of said universal osteotomy device.
6. The surgical method of universal osteotomy device of claim 5 , wherein said angle fixation hole is disposed in said engaging member.
7. The surgical method of universal osteotomy device of claim 6 , wherein the step of inserting said angle fixation bone pin in said angle fixation hole comprises:
inserting a plurality of fixation bone pins in a plurality of fixed holes to maintain said universal osteotomy device.
8. The surgical method of universal osteotomy device of claim 7 , wherein said fixed holes are disposed on said first body component and said second body component.
9. The surgical method of universal osteotomy device of claim 8 , wherein the step of cutting along said guide slot comprises:
cutting along a lateral guide edge.
10. The surgical method of universal osteotomy device of claim 9 , wherein said lateral guide edge is disposed at an end of said upper guide edge.
11. The surgical method of universal osteotomy device of claim 10 , wherein an extended barrier plate is disposed at an end of said lower guide edge to prevent over-cutting on said lateral guide edge.
12. The surgical method of universal osteotomy device of claim 11 , wherein the step of cutting along said lateral guide edge comprises:
inserting at least one osteotome.
13. The surgical method of universal osteotomy device of claim 12 , said first body component further comprising:
a first correcting through-hole being connected to said first body component by a first bar.
14. The surgical method of universal osteotomy device of claim 13 , said second body component further comprising:
a second correcting through-hole being connected to said second body component by a second bar.
15. The surgical method of universal osteotomy device of claim 14 , wherein at least one correction angle between at least one longitudinal axis of said first correcting through-hole and at least one longitudinal axis of said second correcting through-hole are formed.
16. The surgical method of universal osteotomy device of claim 15 , wherein the step of spreading said osteotomy comprises:
inserting an alignment bar in said longitudinal axis of said first correcting through-hole and the corresponding said longitudinal axis of said second correcting through-hole.
17. The surgical method of universal osteotomy device of claim 16 , wherein said at least one correction angle is 1°-45°.
18. The surgical method of universal osteotomy device of claim 17 , wherein a depth of cutting from said upper guide edge and said lower guide edge to a cutting end point is 10 mm-90 mm.
19. The surgical method of universal osteotomy device of claim 18 , wherein an angle between said upper guide edge and said lateral guide edge is 1°-150°.
20. The surgical method of universal osteotomy device of claim 19 , wherein the step of inserting said alignment bar comprises:
maintaining a height of said osteotomy by a distractor.
