Abstract
A surgical effecter, such as a tool, implant or instrument, or a tracking element mounted to the surgical effecter, includes an elongated shaft with a marker affixed thereon that is detectable by cameras or detectors of a localizer or tracking system configured to track the position and orientation of the effecter during a surgical procedure. The marker is wrapped around the circumference of the shaft and presents a top edge and a bottom edge that are perpendicular to the longitudinal axis of the shaft, and a visible spiral edge extending from the top edge to the bottom edge.
