Abstract

A bending tool can be configured to bend an orthopedic implant and includes a first jaw assembly and a second jaw assembly. The first jaw assembly includes a first base and a first adjustment member that is movably coupled to the first base. The second jaw assembly is movably coupled to the second jaw assembly. The second jaw assembly includes a second base and a second adjustment member that is movably coupled to the second base.

First claim

What is claimed:

1. A bending tool that is configured to bend an orthopedic implant that includes a first implant portion and a second implant portion, the bending tool comprising:
a first jaw assembly that includes a first jaw that defines a first engagement surface;
a second jaw assembly that is movably coupled to the first jaw assembly, the second jaw assembly including a second jaw, the second jaw including a base and an adjustment member that defines a second engagement surface, the adjustment member movably coupled to the base such that the second engagement surface is movable with respect to the first engagement surface along a lateral direction with respect to a longitudinal axis of the bending tool, wherein the first and second engagement surfaces are offset from each other along the lateral direction so as to define an adjustment distance that extends from the second engagement surface to the first engagement surface with respect to the lateral direction, such that the first and second engagement surfaces are separated by a gap, wherein the adjustment member is movable with respect to the base so as to adjust the adjustment distance,
wherein movement of the first and second jaw assemblies relative to each other from an open configuration to a closed configuration a) causes at least one of the first and second jaws to move in at least the lateral direction to decrease the adjustment distance, and b) causes the first and second jaws to apply a force to a portion of the orthopedic implant that is disposed in the gap, thereby bending the orthopedic implant such that the first implant portion is offset relative to the second implant portion by an offset distance that is partially defined by the adjustment distance.

2. The bending tool according to claim 1 , wherein the offset distance is defined by a difference between the adjustment distance and a thickness of the portion of the orthopedic implant along the lateral direction.

3. The bending tool according to claim 1 , wherein the adjustment member is configured to translate relative to the base.

4. The bending tool according to claim 1 , wherein the offset distance is a first offset distance of a plurality of offset distances, and the base includes a plurality of base markings, each base marking corresponding to one of the plurality of offset distances, the adjustment member including an adjustment marking, and the adjustment marking is configured to be substantially aligned with one of the plurality of base markings such that the first implant portion can be bent relative to the second implant portion by one of the predetermined offset distances.

5. The bending tool according to claim 1 , wherein the adjustment member is configured to move incrementally relative to the base.

6. The bending tool according to claim 5 , wherein the adjustment member includes an adjustment body and adjustment teeth that protrude from the adjustment body, and the base includes a base body and base teeth that protrude from the base body, the base teeth are configured to mate with the adjustment teeth such that the adjustment member is configured to move incrementally relative to the base.

7. The bending tool according to claim 1 , wherein the base is a second base, the adjustment member is a second adjustment member, and the first jaw includes a first adjustment member and a first base that is movably coupled to the first base.

8. The bending tool according to claim 7 , wherein the first adjustment member is configured to translate relative to the first base.

9. The bending tool according to claim 8 , wherein the first adjustment member is configured to move incrementally relative to the first base.

10. The bending tool according to claim 7 , wherein the first base defines the first engagement surface.

11. The bending tool according to claim 1 , wherein the first and second jaws are configured to move relative to each other in the lateral direction and in a transverse direction that is substantially perpendicular to the transverse direction.

12. The bending tool according to claim 11 , wherein the first jaw assembly includes a first handle member that is coupled to the first jaw, and the second jaw assembly includes a second handle member that is coupled to the second jaw, and the movement of the first and second handle members toward each other causes the first and second jaws to move toward each other toward the closed configuration.

13. The bending tool according to claim 12 , further comprising a biasing member that is connected between the first handle member and the second handle member to bias the first and second handle members away from each other.

14. The bending tool according to claim 1 , wherein the second jaw assembly further comprising a jaw fastener that is connected between the adjustment member and the base, and the jaw fastener is configured to move between an unlocked position and a locked position to fix a position of the adjustment member relative to the base.

15. The bending tool according to claim 1 , wherein a first movement of the first and second jaw assemblies relative to each other cause at least one of the first and second jaws to move in a toward a closed configuration in a first direction that is aligned with the lateral direction, and a second movement of the first and second jaw assemblies relative to each other cause at least one of the first and second jaws to move toward the open configuration in a second direction opposite the first direction so as to increase the adjustment distance.

16. The bending tool according to claim 1 , wherein the second jaw assembly is pivotally coupled to the first jaw assembly.

17. The bending tool according to claim 1 , wherein the first adjustment member is coupled to an elongated member, and rotation of the elongated member causes the first adjustment member to move relative to the base.

18. The bending tool according to claim 17 , wherein the base defines a bore that receives a portion of the elongated member, the base includes inner threads that surround the bore, the elongated member includes external threads that are configured to mate with the inner threads such that rotation of the elongated member causes the elongated member to move relative to the base in the lateral direction.

19. The bending tool according to claim 17 , further comprising a handle that is coupled to the elongated member, wherein the handle is configured to allow a user to rotate the elongated member.

20. The bending tool according to claim 17 , further comprising a support member that is coupled to the elongated member, wherein the support member defines a socket that is configured to receive a driving tool capable of rotating the support member, thereby rotating the elongated member.

21. The bending tool according to claim 1 , where the first engagement surface and the second engagement surfaces are planar surfaces.

22. A bending tool that is configured to bend an orthopedic implant that includes a first implant portion and a second implant portion, the bending tool comprising:
a first jaw assembly that includes a first jaw, the first jaw defining an engagement surface and an outer surface opposed to the engagement surface along a lateral direction with respect to a longitudinal axis of the bending tool;
a second jaw assembly including a second jaw, the second jaw assembly movably coupled to the first jaw assembly such that the first jaw is movable with respect to the second jaw so as to at least partially define
