Abstract
A spinal implant includes a locking mechanism. The locking mechanism includes an inner surface defining a tapered passageway. A tapered collet is configured for disposal in the tapered passageway. The tapered collet has an inner surface defining a passageway configured for disposal of a longitudinal member. The tapered collet is configured to translate within the tapered passageway between a non-locking orientation in which the longitudinal member is moveable relative to the tapered collet and a locking orientation in which the longitudinal member is fixed relative to the tapered collet.
Claims12
A spinal implant including a locking mechanism, the locking mechanism comprising:
- a spinal plate;
- an arcuate collar rotatably disposed in the spinal plate, the arcuate collar comprising an inner surface defining a tapered passageway;
- a longitudinal member;
- and
- a tapered collet configured for disposal in the tapered passageway, the tapered collet having an inner surface defining a passageway configured for disposal of the longitudinal member,
- wherein the tapered collet is configured to translate between a non-locking orientation in which the longitudinal member is moveable within the passageway of the tapered collet and a locking orientation in which the longitudinal member is fixed relative to the arcuate collar and the tapered collet to prevent translation of the longitudinal member while allowing rotation of the arcuate collar and the longitudinal member relative to the spinal plate.
