APPARATUS AND METHODS FOR USE IN MOUNTING A SURGICAL TRAJECTORY GUIDE

摘要

An apparatus (10) and methods for mounting a surgical trajectory guide (12) having a plurality of mounting apertures (14) above a patient's scalp includes a plurality of bone pillars (20) that correspond in quantity to the plurality of mounting apertures (14) in the trajectory guide (12). Each of the bone pillars (20) has oppositely disposed distal (22) and proximal ends (24) and a cylindrical main body section (26) extending between the ends. The distal end (22) of each of the bone pillars (20) includes a self-tapping threaded surface portion (28) for screwing into and through a patient's scalp. The proximal end (24) of each of the bone pillars (20) includes a threaded receptacle (42) for receiving a threaded fastener (16) and a driving surface (40) for engagement by a rotatable member (60) to rotate each of the bone pillars (20).
