Abstract
A dual-lead thread drive screw system for a lateral expanding coaxial spinal implant. The system consists of a centrally located drive screw with lateral actuators. The actuators contain pins positioned through angular slots located on sidewalls attached to endplates. The angular slots provide angular positioning when the actuator pins translate through them. A carriage contains a drive screw for operating of the actuators. Alignment pins provided on each endplate allow the endplates rotate laterally relative to the carriage. An adjustment nut is axially retained by the carriage, but allowed to rotate. To expand/contract the endplates, the drive screw and adjustment nut are rotated together, with no relative motion between them. To change the angle of the endplates, the drive screw is rotated.
