摘要：
A surgical screw driving device for driving a screw into a surgical fixture. The device has a screwdriver having a proximal end, a distal end having a driver for engaging the screw, and an elongated shaft extending therebetween. The device has a screw retainer surrounding and extending along the elongated shaft. The screw retainer is configured to engage and hold a periphery of a screw head prior to the screw being driven into the surgical fixture. The screw retainer is configured to disengage from the periphery of the screw head as an axial end of the screw retainer contacts the surgical fixture and is further configured, upon disengagement and without necessity of outside assistance, to translate along the elongated shaft of the screwdriver away from the distal end and toward the proximal end.
