摘要:
A method and device for inserting screws into a patient, such that when the device is removed the device does not stick to the screw. The device, being a push-off driver, may have a handle, an inner driver, and a threaded driver sleeve having a button mechanism and a plurality of spheres, and an inner sleeve. The method includes the steps of assembling a push-off driver attaching a bone screw to the push-off driver inserting the bone screw and detaching the bone screw from the driver by unthreading the threaded driver sleeve from the polyaxial screw which causes the spheres in the recess of the inner driver to back up against the start of the recess and causing the threaded driver sleeve to “push-off” the polyaxial screw from the inner driver.
