Abstract

A bone anchoring device including a thread (1) whose middle part is in the form of a closed loop (2), and a deformable sleeve (5) which can slide on the thread (1) within the limits of the closed loop (2), wherein the deformable sleeve (5) can be deform into a ball by traction exerted on at least one strand (3, 4) of the thread (1).

Claims

1. A surgical device for anchoring a thread or wire to a bone having a hole bored therein, comprising:

a deformable tubular sleeve which is capable of deforming between a first stretched position of low cross section and a second folded position of greater cross section; and

a thread whose middle part is in the form of a closed loop passing through the deformable tubular sleeve, and wherein the deformable tubular sleeve is able to slide on the thread within the limits of the closed loop.

2. The device according to claim 1, wherein the sleeve can be deformed into a ball by traction exerted on at least one strand of the thread.

3. The device according to claim 1, wherein the length of the sleeve is less than or equal to twice the depth of the hole bored in the bone.

4. The device according to claim 2, wherein the length of the sleeve is less than or equal to twice the depth of the hole bored in the bone.

5. The device according to claim 1, wherein the diameter of the sleeve is less than or equal to the diameter of the hole.

6. The device according to claim 2, wherein the diameter of the sleeve is less than or equal to the diameter of the hole.

7. The device according to claim 3, wherein the diameter of the sleeve is less than or equal to the diameter of the hole.

8. The device according to claim 1, wherein the length of the sleeve is equal to at least 5 times the diameter of the sleeve.

9. The device according to claim 5, wherein the sleeve is made up of a single linear cylindrical element that is open at both of its ends.

10. The device according to claim 9, wherein the sleeve includes at least one orifice extending through its wall dimensioned for the passage of two strands of the thread.

11. The device according to claim 5, wherein the sleeve is made up of a toric ring and including at least two orifices for the passage of the strands of the thread.

12. The device according to claim 5, wherein the sleeve is made up of a toric ring having at least one orifice extending through its wall dimensioned for the passage of the strands of the thread.

13. The device according to claim 10, wherein the wall of the tubular sleeve has at least two orifices extending through it for the passage of the strands of the thread, these orifices being arranged in such a way that the traction exerted on the strands of the thread causes a tilting movement of the sleeve.

14. The device according to claim 11, wherein the wall of the toric ring has at least two orifices extending through it for the passage of the strands of the thread, these orifices being arranged in such a way that the traction exerted on the strands of the thread causes a tilting movement of the sleeve.

15. The device according to claim 12, wherein the wall of the tubular sleeve has at least two orifices extending through it for the passage of the strands of the thread, these orifices being arranged in such a way that the traction exerted on the strands of the thread causes a tilting movement of the sleeve.
