Transverse rod connector clip
First Claim
1. A spinal fixation system comprising:
- a) a first clip body having a pair of opposed spaced apart arcuate rod engaging hooks for engaging a first elongated spinal rod and a laterally extending transverse connector;
b) a second clip body having a pair of opposed spaced apart arcuate rod engaging hooks for engaging a second elongated spinal rod and a laterally extending transverse connector; and
c) a fastener for securing the transverse connector of the first clip body and the transverse connector of the second clip body to one another, the fastener having an inner portion with an outer surface and an outer portion with an inner surface, the inner surface of the outer portion being adapted and configured to slidably engage the outer surface of the inner portion to radially compress the inner portion.

Abstract
A transverse connector clip for connecting cylindrical rods to each other in a spinal fixation system, comprising a clip body having two sides. The first side of the clip body has a longitudinal axis and a pair of mirror image hemi-cylindrical shells. These hemi-cylindrical shells have an inner diameter that is slightly smaller than the outer diameter of a cylindrical rod. The clip body is shaped so as to allow the hemi-cylindrical shells to spread around the cylindrical rod when the cylindrical rod is inserted between said shells and to securely clamp on the cylindrical rod at a 90° angle relative to the clip body The second side of the clip body can comprise one of several embodiments; a short laterally extending hemi-cylinder rod, a laterally extending hemi-cylinder rod with a plurality of vertical teeth, a second pair of mirror image hemi-cylindrical shells, a laterally extending rod tapering from a proximal cylindrical shape to a distal hemi-cylinder shape, or a body portion and a locking mechanism configured to receive and lock a hemi-cylindrical or cylindrical rod.
