Abstract
The present invention relates to tools and methods for cutting the annulus of a spinal disc. The cutting tools of the invention may be cannulated for use in conjunction with a guide wire. A stop surface of the cutting tool is configured to contact the annulus during cutting to prevent further longitudinal movement of the surgical blade(s) into the annulus, thus limiting the size of the incision(s).
