Claim 15:
16. A method, comprising:
coupling a drill to a neuromonitoring bone drill bit, wherein an electrically insulating shield and an electrically insulating cover extend over the neuromonitoring bone drill bit;
coupling a neuromonitoring clip to the neuromonitoring bone drill bit;
securing a locking system in an unlocked position to allow the electrically insulating shield to withdraw proximally in response to engagement of the electrically insulating shield with a bone of a subject;
advancing the neuromonitoring bone drill bit into the bone of the subject, wherein advancing the neuromonitoring bone drill bit into the bone of the subject causes the electrically insulating shield extending over a distal end portion of the neuromonitoring bone drill bit to withdraw proximally relative to the distal end portion as the neuromonitoring bone drill bit advances into tissue the bone of the subject; and
withdrawing the neuromonitoring bone drill bit from the bone of the subject, wherein withdrawing the neuromonitoring bone drill bit from the bone of the subject causes the electrically insulating shield to advance distally over the distal end portion of the neuromonitoring bone drill bit.
