    摘要： A surgical drill assembly is provided that includes an elongate shaft having a proximal end adapted to mate to a driver mechanism, and a distal end having a bone preparation element formed thereon. An elongate, hollow sleeve is coupled to, but slidably disposed around at least a portion of the elongate shaft. The hollow sleeve includes a stepped region that is positioned between proximal and distal portions such that the distal portion has an outer diameter that is less than an outer diameter of the stepped region to allow the distal portion to be disposed within a lumen in a drill guide, and the stepped region to abut the drill guide. In use, the elongate, hollow sleeve is effective to longitudinally align the elongate shaft therein during a surgical procedure. The elongate shaft can also optionally include a stop member that is effective to limit penetration depth of the bone preparation element with respect to the hollow sleeve.

    摘要： A drill guide for use in securing a spinal fixation plate to a spine is provided. In a preferred embodiment, the drill guide generally includes a support member having first and second arms mated thereto. Each arm includes a proximal end and a distal end having at least one barrel coupled thereto and defining a lumen for receiving a tool. One or both arms can be slidably movable along the support member to allow the distance between the arms to be adjusted. In use, the arms can be adjusted to engage a spinal fixation plate and to position the barrels on each arm in alignment with bores formed in the fixation plate. The drill guide can then be used to drill, awl, tap, and insert implants, such as spinal screws, into the vertebral bodies to attach the fixation plate thereto.
