A method of surgical navigation into' the brain includes establishing a trajectory through the skull into the brain to a target, drilling a hole in the skull using a drill (14), and verifying the trajectory of the drilled hole during drilling using image guidance. A surgical navigation system includes a cannulated drill, a cannulated access member (30), and a coupling member (16) for coupling the access member to the drill and for maintaining alignment of the cannulations in the drill and the access member. The access member is movable relative to the coupling member such that the access member can be secured to tissue while the coupling member maintains the alignment of the cannulations. A surgical kit includes a cannulated drill, a cannulated access member, a coupling member for coupling the access member to the drill, and a probe for receipt within the cannulated drill.
