BAYONET REGISTRATION TOOL/PROBE

The present disclosure provides new and innovative systems and apparatuses for a surgical registration probe that provides improved detection by a surgical navigation system (e.g., localizer). An example apparatus includes a surgical registration probe; a localizer configured to track the surgical registration probe; and a surgical visualization system (e.g., localizer) configured to display a surgical site responsive to the tracking. The surgical registration probe may include: a marker shaft with at least one marker or fiducial; wherein the marker or fiducial causes the localizer to detect the surgical registration probe; and a probe shaft having at least three sections that are bent at a defined angle with respect to each other. In some embodiments, the apparatus may further comprise a calibration plate for securing the surgical registration probe.
