Abstract

An insertion instrument for expandable spinal implants includes an elongate member, a shuttle, and a worm gear. The elongate member includes a handle portion of a proximal end and an end effector on a distal end, wherein the end effector is configured to be releasably engaged to an expandable spinal implant. The shuttle is slidably disposed within a cavity defined within the end effector and includes a wedged shaped distal end configured to engage an expandable spinal implant. The worm gear is rotatably disposed within the cavity defined in the end effector and is in mechanical communication with the shuttle, such that rotation of the worm gear effectuates movement of the shuttle. Distal movement of the shuttle effectuates articulation of an expandable spinal implant. A method of performing surgery is also disclosed.
