BOTTOM LOADING CONNECTOR FOR ATTACHING A SPINAL ROD TO A VERTEBRAL MEMBER

摘要

Connectors for attaching a spinal rod to an anchor. The connectors may include a receiver with a rod-receiving opening on a bottom side that leads into a receiver passage sized to receive the spinal rod. A elongate member may extend through an opening on the top side of the receiver, and may include a cut-out to receive the spinal rod. A grommet may be operatively connected to the receiver and include a grommet passage to receive the anchor. A disk may be positioned between the receiver and the grommet and may include an angled surface that is positioned on a side of the receiver passage. The elongate member may be movable along the first axis between extended and retracted positions with the cut-out positioned closer to the second axis in the retracted position than in the extended position. Moving the elongate member from the extended position to the retracted position with the spinal rod received in the cut-out may cause the disk to move along the second axis towards the grommet passage to fix the first axis in spaced relation relative to the grommet passage.
