Abstract
A quick release device for a powered surgical instrument, for example, a Mueller osteotomy saw, includes a coupling having a spindle which forms a mounting surface, the spindle being driven with the coupling by the power source. Located on the spindle is a locking pin assembly movable between a locking and an unlocking position, the spindle cooperating with a plurality of concentrically disposed latching pins which latch the medical instrument to the spindle in driving relationship therewith. The medical instrument, for example, a saw blade, includes a predetermined number of apertures corresponding to the number of latching pins on the spindle, each of the apertures including a pin receiving end and a latching end. Eccentrically positioned with respect to the apertures is a locking pin receiving aperture through which the locking pin on the spindle is received. The instrument is assembled over the locking pin which has been depressed, moved such that the latching pins are received by the latching pin apertures, and then manipulated such that the latching pins are urged into the latching end of the apertures. Upon release of the now aligned locking pin which includes an outer taper…
