Patent ID: 8403932

Claim:
A cutting guide and saw blade assembly, said assembly comprising: a cutting guide having a body shaped to be positioned against tissue to be cut, said body having: a guide surface that is an exposed surface of said body; and features for receiving fasteners that hold said body to the tissue against which said cutting guide is positioned; a saw blade assembly, said saw blade assembly having: a bar having opposed proximal and distal ends, the proximal end shaped to be attached to a saw and the distal end having a thickness; a blade having a base that is movably mounted in said bar adjacent the bar distal end and a head integral with said base that is located outside of said bar, said head having a thickness at least equal to the thickness of the bar distal end and having teeth; and at least one drive rod moveably disposed in said bar, said at least one drive rod having a proximal end shaped to be attached to a driver integral with the saw and a distal end connected to said blade base so that the actuation of said drive rod by the saw driver results in said drive rod oscillating said blade around a pivot point; and a coupling assembly having a first feature attached to said cutting guide body and a second feature integral with said saw blade assembly bar, said features configured to moveably hold said saw blade assembly bar to said cutting guide body on the cutting guide guide surface so that, said saw blade assembly bar is able to move over the guide surface and is constrained from movement outside of a plane above the guide surface.
