1. A surgical effecter, comprising:
an elongated shaft having a circumference and defining a longitudinal axis; and
a marker including a sheet wrapped around the circumference of the shaft, the sheet including;
a perimeter;
a lower edge and an opposite upper edge at the perimeter that are parallel to each other and that are arranged perpendicular to the longitudinal axis of the shaft; and
a visible edge at the perimeter extending between the lower and upper edges at a non-perpendicular and non-colinear angle relative to the longitudinal axis of the shaft,
wherein said sheet is formed of a material 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.
