Abstract

A surgical sagittal saw blade and a complementary cutting guide for use with the blade. The blade includes a bar shaped to be releasably secured in a static position to a complementary surgical sagittal saw. A blade head with teeth is mounted to the bar to pivot. One or more drive links connected to the saw extend to the blade head to pivot the blade head. The cutting guide and blade bar have complementary features for holding the blade bar to above a surface of the cutting guide. The features that hold the blade bar to the cutting guide allow the blade to move over the cutting guide surface while constrain the blade from moving out of the plane immediately above the cutting guide surface.
