Abstract

A surgical sagittal and a saw blade cartridge. The saw has a head to which the blade cartridge is releasably mounted and a clamping assembly that releasably hold the cartridge to the head. The blade cartridge includes a blade bar, a blade head mounted to the bar and at least one drive rod that actuates the blade head. A rib projects from the blade bar to stiffen the cartridge. The rib extends over the blade bar so as to extend both proximally and distally relative to where the clamp assembly bears against the blade bar. The rib reduces skiving of the cartridge when a load is applied to either the top or bottom surface of the blade bar.
