A surgical sagittal saw blade assembly and cutting guide for use with the blade assembly. The blade assembly includes a static bar from which a moving blade head protrudes. The blade head is reciprocated by a drive link internal to the bar. The cutting guide has a body that is positioned adjacent where the blade is to be used to cut tissue. The cutting guide has an outer surface over which the blade assembly is positioned. The cutting guide has a constraining feature. The constraining feature holds the blade bar to the body of the guide so the blade assembly can move over the body while being constrained from movement above the outer surface of the body. The constraining feature is mounted to the body of the cutting guide so as to be able to move while constraining guide retains the blade bar.

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.
