Abstract

A universal rod holder including a drive member and an elongated shaft member. The drive member has a proximal portion and a distal portion, and may include a handle disposed on the proximal portion, external threads disposed on the proximal portion of the drive member, and a tip disposed on a distal end of the distal portion of the drive member. The elongated shaft member includes a through hole, the through hole configured to receive the drive member, internal threads disposed on an inner surface of the through hole and configured to engage the external threads, and a hook member disposed on a distal end of the shaft member. The through hole extends into an opening of the hook member. The distal portion of the drive member is configured to slide through the through hole and into the opening of the hook member to secure a rod positioned therein.

First claim

What is claimed:

1. A universal rod holder comprising:
a drive member having a proximal portion and a distal portion, the drive member including:
a handle disposed on the drive member;
external threads disposed on the proximal portion of the drive member; and
a tip disposed on a distal end of the distal portion of the drive member;

a shaft member including a through hole having an aperture at a distal end of the shaft, the through hole configured to receive the drive member in a coaxial arrangement;
internal threads disposed on an inner surface of the through hole, the internal threads configured to engage the external threads; and
a hook member disposed on a distal end of the shaft member, the hook member having an opening transverse to the aperture, wherein the distal portion of the drive member is configured to slide through the through hole such that the tip of the drive member is proximate an inner wall of the hook member.

2. The universal rod holder according to claim 1 , wherein the proximal portion of the drive member has a first diameter and the distal portion of the drive member has a second diameter, wherein the first diameter is larger than the second diameter.

3. The universal rod holder according to claim 1 , further including an anti-torque tool, wherein the shaft member includes a neck portion configured to releasably engage the anti-torque tool.

4. The universal rod holder according to claim 1 , wherein rotation of the drive member relative to the shaft member causes longitudinal movement of the distal portion of the drive member through the through hole.

5. The universal rod holder according to claim 1 , wherein the tip of the drive member has a non-planar configuration.

6. The universal rod holder according to claim 1 , wherein the tip of the drive member has a planar configuration.

7. The universal rod holder according to claim 3 , wherein engagement of the shaft member with the anti-torque tool inhibits rotation of the shaft member in a direction orthogonal to a longitudinal axis of the drive member.

8. The universal rod holder according to claim 1 , wherein the opening of the hook member is configured to receive a spinal rod therethrough and the inner wall is configured to receive the spinal rod thereon.

9. The universal rod holder according to claim 3 , wherein the anti-torque tool defines a receiving member, and the neck portion of the shaft member is disposed between a proximal portion and a distal portion thereof, the receiving member of the anti-torque tool includes an open end to selectively receive the neck portion therein.

10. The universal rod holder according to claim 1 , wherein the hook member defines a generally “C” shape.

11. The universal rod holder according to claim 1 , wherein a longitudinal axis of the shaft member is transverse to the opening of the hook member.

12. The universal rod holder according to claim 1 , wherein the shaft member includes a proximal portion, a distal portion, and the through hole extends therebetween.

13. The universal rod holder according to claim 1 , wherein the shaft member, the through hole, the aperture, and the drive member are configured to define a coaxial arrangement.

14. The universal rod holder according to claim 1 , wherein the aperture and the through hole of the shaft member are in communication with the opening of the hook member.
