SURGICAL SAGITTAL BLADE CARTRIDGE

A surgical sagittal saw cartridge that includes a guide bar formed from an inner plate and opposed outer plates. The cartridge has a blade that extends distally from the guide bar, the blade comprising a blade head including a plurality of teeth. The plurality of teeth may include a combination of pilot teeth and base teeth, the pilot teeth configured to extend distally beyond the base teeth. The inner plate may comprise an inner tine and/or two opposed outer tines. The inner tine may be formed to define the head against which the blade is configured to pivot about. The inner plate may be configured to have opposed edges that extend beyond the opposed edges of the outer plates to define a mounting feature. The inner plate may also define a reference feature configured to register and/or verify the pose of the cartridge with a navigation system.
