Claim Text:
1. A method of assembling a surgical sagittal saw, said method including the steps of: providing an oscillating head, the oscillating head having: a top located feature for removably holding a surgical sagittal saw blade to the head; a longitudinal axis that extends top-to-bottom through the head; and an elongated trunk that extends along the longitudinal axis, the elongated trunk being formed with at least one tapered surface such that, extending along the tapered surface from a bottom of the tapered surface to a top of the tapered surface, the distance between the longitudinal axis of the head and the tapered surface changes; providing a yoke, the yoke having: features for engaging a drive shaft capable of oscillating the yoke; and a bore, the bore shaped to receive the trunk of the oscillating head, the bore being defined by at least one yoke tapered surface that is complementary to the tapered surface of the trunk of said oscillating head; mounting the oscillating head to the yoke so the trunk of the oscillating head is seated in the bore of the yoke such that the tapered surface of the trunk of the oscillating head abuts the tapered surface of the yoke; pressing the oscillating head and the yoke together so the tapered surface of the trunk of the oscillating head presses against the tapered surface of the yoke so the oscillating head and the yoke become a single unit; and mounting the oscillating head and attached yoke to a saw body that includes a drive shaft so that the yoke engages the drive shaft and the oscillating head is able to oscillate so that the actuation of the yoke by the drive shaft results in the back and forth oscillations of the oscillating head around the longitudinal axis of the oscillating head.
