Abstract
A bone screw driver () for inserting a bone screw () into a bone region (A) includes a driver shaft (B) that selectively engages the bone screw (). The bone screw () includes a screw threaded region (A) and a screw engagement region (B). The screw engagement region (B) includes a screw shaft (D) and an engager ring (E). The driver shaft (B) includes a shaft aperture (), a first resilient member (A), and a first shaft projection (A). The shaft aperture () receives at least a portion of the screw shaft (D), the first resilient member (A) engages the screw shaft (D) to inhibit movement of the screw shaft (D), and the first shaft projection (A) engages the engager ring (E) so that rotation of the driver shaft (B) results in rotation of the bone screw (). With this design, in certain embodiments, the bone screw () can be removed with the bone screw driver () from a screw retainer () that retains the bone screw (), and inserted into the bone region (A) without the physician contacting with the bone screw (). This reduces the likelihood of contaminating the bone screw () and increases the likelihood of success for the procedure.
