Abstract
A cannulated driver includes a handle, a barrel coupled to the handle, and a drive tip coupled to the barrel and having an outer surface and an engagement end that engages within a head of a cannulated screw. The driver is configured to removably retain a corresponding cannulated screw onto the driver. The drive tip includes a passageway disposed generally in a radial direction with respect to the driver's longitudinal axis. An engagement pin is movably mounted for travel in the passageway between an extended position wherein an exposable end of the pin protrudes radially beyond the outer surface of the drive tip and a retracted position wherein the pin does not thus protrude. In the extended position, the exposable end of the pin protrudes into a corresponding recess in the head of a special cannulated screw to removably retain the screw onto the driver.
