Surgical Saw for Actuating a Saw Blade with an Oscillating Head, the Saw Having a Coupling Assembly for Releasably Holding the Saw Blade

A surgical sagittal saw for use with a complementary blade assembly that includes a static bar. The saw includes a head over which the blade assembly bar is seated. A coupling rod is able to be mounted to the head to move along the longitudinal axis of the rod. The coupling rod has a head that, as result of the longitudinal movement of the rod is moved towards and away from the head. A blade assembly may be disposed on the saw head adjacent the coupling rod. The coupling rod can be positioned in a run state so that the rod head abuts the bar of the blade assembly so as to hold the blade assembly to the saw head. Alternatively, the coupling rod can be repositioned in a load state the rod head is spaced from the saw head. This allows the blade assembly to be removed and replaced.
