Surgical saw for actuating a saw blade with an oscillating head, the saw having a coupling assembly for releasably holding the saw blade

Abstract

A method of navigating a surgical saw with a navigation system having a navigation processor. The method comprising attaching a saw blade to a head of the surgical saw and determining a position of the surgical saw. The method also comprises touching a tracked pointer to one or more reference points on the saw blade and tracking the position and orientation of the tracked pointer as the tracked pointer is touched to the one or more reference points on the saw blade. The method further comprises determining an angular orientation of the saw blade based on the tracked pointer and the one or more reference points on the saw blade, and the navigation system determining the position and orientation of the saw blade relative to saw based on the position and orientation of the saw, the angular orientation of the saw blade, and a characteristic of the saw blade.
