Abstract
A surgical sagittal saw blade with a static blade bar shaped to be coupled to a sagittal saw. At least one drive rod extends through the bar. The drive rod is moveable within the blade bar. A blade crown, located outside the distal end opening of the blade bar is connected to the drive rod. The actuation of the drive rod by the saw results in the oscillation of the blade crown. Proximal to the distal end of the blade bar, the bar is formed with secondary openings. When the drive rod and blade crown are actuated, tissue entrained in the blade bar is discharged from the secondary openings.
