Abstract
A surgical sagittal saw including a handpiece from which a planar guide bar extends. A saw blade is mounted to the distal end of the guide bar to move across the guide bar. Drive rods connect the saw blade to a drive assembly in the handpiece, which drive assembly reciprocates the drive rods. The drive rods oscillate the saw blade across the distal end of the guide bar. The saw is used with a cutting guide that is in a fixed position relative to the bone or hard tissue to be cut. A capture element is disposed adjacent the guide surface and holds the guide bar to the guide surface so the cut is made along the desired cut plane.
