Abstract:
1. A spinous process retractor surgical instrument, comprising: a pair of opposing proximal handles coupled to a pair of opposing distal jaws through a single joint such that when the handles are compressed the jaws spread apart, the handles defining a plane when viewed from the side; the jaws curving downwardly from the plane distally from the joint, the jaws then curving back upwardly before terminating in end portions configured for spreading; the instrument defining a centerline when viewed from above, the jaws distally from the joint diverging outwardly from the centerline, then curving back toward the centerline before terminating in the end portions; and wherein the end portion of each jaw comprises a single flat surface that faces the single flat plate of the opposing jaw, such that the single flat surfaces contact each other when the jaws are closed; and wherein the end portions of the jaws further include opposing, outwardly facing textured or roughened bone-contacting surfaces.
