Claims
- 1. A surgical kit for implanting a spinal fusion implant into a disk space of disk material separating a first and second vertebrae, said disk space and first and second vertebrae divisible into first and second sides separated by a sagittal plane, said kit comprising:
- a distraction plug sized smaller than said implant and further sized to be inserted between said vertebrae on at least one of said sides and with said distraction plug further sized for external surfaces of said distraction plug to urge against end-plates of said vertebrae to urge said vertebrae apart by a distraction equal to an external sizing of said plug;
- a guide pin sized approximate to said sizing of said plug;
- a drill tube guide attached to said guide pin on a distal end of said drill tube guide with said drill tube guide having predetermined external dimensions;
- a drill tube sized to be received upon said drill tube guide with said drill tube guide within said drill tube and with external surfaces of said drill tube guide in close tolerance with internal surfaces of said drill tube and with means on a distal end of said drill tube for fastening said drill tube to said vertebrae; and
- a boring tool having a proximal end with means for boring into said vertebrae and with said boring tool sized to be received within said drill tube with said drill tube acting against external surfaces of said boring tool to guide said boring tool.
- 2. A kit according to claim 1 comprising a drill tube planer having means on a distal end thereof for rasping said vertebrae with said drill tube planer hollow and sized to be received upon said drill tube guide in close tolerance.
- 3. A kit according to claim 1 further comprising an implant driver having means on a distal end thereof for releasably engaging an implant and turning said implant upon turning of said driver, said driver sized to be slidably received within said drill tube.
- 4. A kit according to claim 3 wherein each of said implant driver and drill tube includes cooperating stop surfaces to limit advancement of said implant driver toward said disk space.
- 5. A kit according to claim 1 wherein said boring tool includes means on a distal end thereof for boring into said vertebrae upon turning of said boring tool and further having means on said distal end for releasably receiving said guide pin;
- said boring tool sized to be received within said drill tube.
- 6. A kit according to claim 1 wherein each of said boring tool and drill tube includes cooperating stop surfaces to limit a depth of penetration of said boring tool into said disk space.
