Abstract

A surgical reduction clamp has a first clamping arm and a second clamping arm movable relative to the first clamping arm. The first clamping arm comprises a base portion, a tip portion, a joint movably coupling the tip portion to the base portion, and a locking member adapted to lock the joint so as to fasten a position of the tip portion relative to the base portion. The joint is a revolute joint having a spherical portion which can be locked into position by a clamping force.

First claim

The invention claimed is:

1. A surgical reduction clamp comprising a first clamping arm and a second clamping arm movable relative to the first clamping arm, the first clamping arm comprising:
a base portion;
a tip portion;
a joint movably coupling the tip portion of the first clamping arm to the base portion of the first clamping arm;
a locking member adapted to lock the joint so as to fasten a position of the tip portion of the first clamping arm relative to the base portion of the first clamping arm;
wherein the tip portion of the first clamping arm comprises a sleeve having a longitudinal axis substantially perpendicular to a longitudinal axis of the first clamping arm throughout an entire range of movement of the tip portion with respect to the longitudinal axis of the first clamping arm;
wherein the second clamping arm comprises a base portion and a tip portion comprising an elongate member; and
wherein the first and second clamping arm are pivotably coupled to one another.

2. The clamp according to claim 1 , wherein the joint rotatably couples the tip portion of the first clamping arm to the base portion of the first clamping arm.

3. The clamp according to claim 2 , wherein the tip portion of the first clamping arm is rotatable about a longitudinal axis of the first clamping arm.

4. The clamp according to claim 1 , wherein the joint couples the tip portion of the first clamping arm to the base portion of the first clamping arm by means of a revolute joint.

5. The clamp according to claim 1 , wherein the joint pivotably couples the tip portion of the first clamping arm to the base portion of the first clamping arm.

6. The clamp according to claim 1 , wherein the locking member is adapted to lock the joint by applying a clamping force.

7. The clamp according to claim 1 ,
wherein the locking member comprises a handle to lock or release the joint.

8. The clamp according to claim 1 ,
wherein the locking member comprises a screw head to lock or release the joint.

9. The clamp according to claim 1 ,
wherein the tip portion comprises a sharp bone tip.

10. The clamp according to claim 1 , wherein the tip portion of the first clamping arm is releasable from the base portion of the first clamping arm and interchangeable.

11. The clamp according to claim 1 , wherein a spring is formed between the first and the second clamping arm so as to bias the first and the second clamping arm relative to each other.

12. The clamp according to claim 1 , wherein a ratchet toothed member is formed at one of the first and second clamping arm and extends towards the other clamping arm so as to permit locking of a position of the first and the second clamping arm relative to one another by engagement of the other clamping arm with teeth of the ratchet toothed member.

13. The clamp according to claim 1 , wherein the tip portion of the second clamping arm is integrally joined to the second clamping arm.

14. The clamp according to claim 1 , wherein the tip portion of the second clamping arm comprises a sleeve.

15. A surgical reduction clamp comprising a first clamping arm and a second clamping arm movable relative to the first clamping arm, the first clamping arm comprising:
a base portion;
a tip portion;
a joint movably coupling the tip portion of the first clamping arm to the base portion of the first clamping arm; and
a locking member adapted to lock the joint so as to fasten a portion of the tip portion of the first clamping arm relative to the base portion of the first clamping arm, wherein the joint rotatably couples the tip portion of the first clamping arm to the base portion of the first clamping arm by means of a revolute joint, wherein the locking member is adapted to lock the revolute joint by applying a clamping force to a portion of the joint; and
wherein the tip portion of the first clamping arm comprises a sleeve having a longitudinal axis substantially perpendicular to a longitudinal axis of the first clamping arm throughout an entire range of movement of the tip portion with respect to the longitudinal axis of the first clamping arm;
wherein the second clamping arm comprises a base portion and a tip portion comprising an elongate member; and
wherein the first and second clamping arm are pivotably coupled to one another.

16. The clamp according to claim 15 , wherein the tip portion of the first clamping arm has a cylindrical portion having a spherical end which spherical end portion forms part of the revolute joint.
