20150201982 | Anterior cervical plate - An anterior cervical plate system is provided. The cervical plate includes an actuator and two locks located between two holes adapted to receive fasteners. Each lock includes a pair of fingers oppositely disposed from a fastener retaining flange. The retaining flange face the holes and the fingers face each other with the actuator located between the fingers. The actuator includes an elongated body. As the actuator is rotated from an unlocked to a locked position, the elongated body pushes both locks simultaneously outwardly to retain fasteners placed inside the holes. As the actuator is rotated in the opposite direction to an unlocked position, the elongated body catches hooks on the fingers to pull the locks inwardly away from holes. The locks are configured to prevent bone fasteners from backing out of the plate. | 07-23-2015 |
20140135848 | Anterior cervical plate - An anterior cervical plate system is provided. The cervical plate includes a retention ring with a deflectable flange that is upwardly spaced from the top surface of the ring and configured to prevent an inserted bone fastener from backing out of the plate. The plate includes a locking pin having a camming surface and a blocking surface. When the camming surface is moved into position adjacent to the flange, the flange is free to flex out of the way of a bone screw being inserted into or removed from the plate. When the blocking surface is positioned adjacent to the flange, outward deflection of the flange is prevented to retain the bone screw inside the plate. The locking pin is rotated through a camming surface to bring a blocking surface against the flange deflecting the flange onto the head of the bone screw. | 05-15-2014 |
