Abstract

Connector assemblies, systems, and methods thereof. An articulating connector has a first end that clamps to a first rod in an existing construct and a second end having a second end that clamps to a second rod in a new construct or such that the new construct can be extended from the existing construct. In the case of different sized constructs used in different areas of the spine, an articulating connector has a first end that clamps to a first rod in a new construct having rods of a first size and a second end having a second end that clamps to a second rod in a new construct having rods of a second size. The clamping portions are capable of translating and rotating with respect to each other.

First claim

What is claimed is:

1. A connector system comprising:
a connector having a body having a first clamping portion and a second clamping portion;
the first clamping portion having:
a first passageway having a first longitudinal axis extending therethrough and being sized to allow a first rod to be inserted therein;
a bottom portion having a first opening in communication with the first passageway;
two opposing legs, the first passageway defined between the two opposing legs; and
a first securing mechanism positioned at least in part in the first passageway, the first securing mechanism capable of moving from a first position to a second position; and

the second clamping portion having:
a second passageway having a second longitudinal axis extending therethrough and being sized to allow a second rod to be inserted therein;
a post extending from the second clamping portion and having a partially cylindrical outer surface, the post being configured and

dimensioned to be received in the first opening,

wherein the first clamping portion and second clamping portion are configured to rotate and/or translate relative to each other,
wherein the first clamping portion includes a second opening configured to receive a pin, the pin is positioned perpendicularly to the post and positioned under the post, wherein the pin is positioned perpendicular to a longitudinal axis of the first clamping portion, and wherein the pin is configured to engage with the post to limit translation and rotation of the post.

2. The system of claim 1 , wherein the second clamping portion comprises two opposing legs, the second passageway defined between the two opposing legs.

3. The system of claim 1 , further comprising a locking cap configured and dimensioned to engage the opposing legs of the first clamping portion after the first rod is received in the first passageway.

4. The system of claim 3 , wherein rotation of the locking cap results in the locking cap pushing on the first rod which results in the first rod pushing on the securing mechanism moving the securing mechanism from the first position to the second position, wherein in the second position, the securing mechanism prevents movement of the first clamping portion with respect to the second clamping portion.

5. The system of claim 4 , wherein the securing mechanism is a saddle comprising a projection portion.

6. The system of claim 1 , wherein the second rod is larger than the first rod.

7. The system of claim 1 , wherein the first clamping portion and the second clamping portion each have outer surfaces and wherein at least one of the outer surfaces of the first clamping portion and the second clamping portion includes a pair of dovetails for engaging with a reduction instrument.

8. A connector system comprising:
a connector having a body having a first clamping portion and a second clamping portion;
the first clamping portion having:
a first passageway having a first longitudinal axis extending therethrough and being sized to allow a first rod to be inserted therein;
a bottom portion having a first opening in communication with the first passageway and a second opening configured and dimensioned to receive a pin member;
two opposing legs, the first passageway defined between the two opposing legs; and
a first securing mechanism positioned at least in part in the first passageway, the first securing mechanism capable of moving from a first position to a second position; and

the second clamping portion having:
a second passageway having a second longitudinal axis extending therethrough and being sized to allow a second rod to be inserted therein;
a post extending from the second clamping portion, the post being configured and dimensioned to be received in the first opening,

wherein the first clamping portion and second clamping portion are configured to rotate and/or translate relative to each other
wherein the pin member is positioned perpendicularly to the post and positioned, wherein the pin member is positioned perpendicular to a longitudinal axis of the first clamping portion, and wherein the pin member is configured to engage with the post to limit translation and rotation of the post.

9. The system of claim 8 , wherein the post has a cutout on a lower surface, the cutout configured and dimensioned to engage with the pin member to limit translation and rotation of the first clamping portion relative to the second clamping portion.

10. The system according to claim 8 , wherein the post has an upper surface that includes texturing.

11. The system of claim 8 , further comprising a locking cap configured and dimensioned to engage the opposing legs of the first clamping portion after the first rod is received in the first passageway.

12. The system of claim 11 , wherein rotation of the locking cap results in the locking cap pushing on the first rod which results in the first rod pushing on the securing mechanism moving the securing mechanism from the first position to the second position, wherein in the second position, the securing mechanism prevents movement of the first clamping portion with respect to the second clamping portion.

13. The system of claim 8 , wherein the second clamping portion comprises two opposing legs, the second passageway defined between the two opposing legs.

14. The system of claim 13 , further comprising a locking cap configured and dimensioned to engage the opposing legs of the second clamping portion after the second rod is received in the second passageway.
