Patent ID: 8043292

Claim:
A blade assembly for attachment to a surgical sagittal saw, the saw having a moveable driver, said blade assembly having: a guide bar having opposed proximal and distal ends, the proximal end being shaped to be received by the saw and to cooperate with a saw fastening unit so that the fastening unit releasably holds said guide bar in a static state to the saw, the distal end of said guide bar having a thickness; a blade including: a base at least partially disposed inside said guide bar that is pivotally mounted to said guide bar adjacent the distal end of said guide bar; and a head integral with said base that is located outside of said guide bar, said blade head having a thickness at least equal to the thickness of the distal end of said guide bar and said blade head having teeth; and two drive rods that are connected to and that extend proximally away from said blade, said drive rods being connected to said blade on opposed sides of a pivot point around which said blade pivots, each said drive rod having a proximal end and a coupling feature that releasably couples said drive rods to the saw driver so that the actuation of the driver results in the simultaneous opposed reciprocation of said drive rods so that said drive rods oscillate said blade about the pivot point.
