Abstract

A disc preparation system includes an oscillating rasp for preparation of vertebral endplates and a central reamer for reaming a pair of kidney-shaped grooves into the vertebral endplate. The oscillating rasp is powered by a rotary power source. A linkage assembly is coupled to the rotary power source to convert the rotary motion into a reciprocating motion. A pair of rasps plates, which are linked to the linkage assembly, linearly reciprocate in opposite directions in response to the reciprocating motion of the linkage assembly. In one form, the central reamer includes a pair of cutting elements that are coupled to the rotary power source in order to rotate in response to rotational movement from the rotary power source. In another form, the central reamer includes a single cutting element coupled to an angled reamer handle and a reamer guide.
