1. A tracking array for surgical navigation, the tracking array comprising:
a three-dimensional structure having:
a first cylindrical body extending along a longitudinal axis, the first cylindrical body including a cavity located therewithin, an outer surface on the first cylindrical body, and
a neck region including a second cylindrical body within the cavity extending along the longitudinal axis beyond a distal end of the first cylindrical body, defining a cavity between an inner surface of the first cylindrical body and the neck region;
a plurality of tracking markers arranged on the outer surface of the first cylindrical body, the plurality of tracking markers configured to be detectable by an image capturing device, wherein the plurality of tracking markers are disposed around a circumference of the first cylindrical body; and
an attachment feature in the second cylindrical body configured to releasably and securely attach the tracking array to an elongate surgical shaft having a stimulation electrode disposed at its distal tip at a predetermined circumferential angle, wherein the first cylindrical body includes a visual orientation marker which is circumferentially aligned with the stimulation electrode when the second cylindrical body is attached to the elongate surgical shaft.
