Abstract
The surgical instrument includes a handle assembly and an elongate body that has first and second ends with the first end being located adjacent to the handle assembly and the second end being moveably connected to an implant engagement assembly. The surgical instrument also has a length control mechanism that includes a gripping portion, a drive shaft and a gear assembly. The surgical instrument further has a locking mechanism that includes a gripping portion, a connecting rod and a coupling end. The length control mechanism functions to adjust the overall length of an implant that is held by the implant engagement assembly before being implanted in vivo. The locking mechanism operates to secure the overall length of the implant following final length adjustment and implantation. A surgical method for using the surgical instrument, a method of fabrication and a spinal implant insertion kit is also disclosed.
