Abstract

Surgical curettes or rakes with cutting edges conform or deflect to allow for contouring that follows the bony anatomy. The cutting tips can be pre-sterile, disposable and made from flexible materials including metals and polymers. The disposable tips ensure that a sharp cutting edge is exposed to the endplate for each procedure. The tips can also be adjusted to change the size of the cutting surface and window for retaining shaved disc material. The tips can pivot to provide for a self adjusting angle that allows the cutting edge to have full contact with the endplate at various angles like the pivot on a disposable razor blade.
