摘要

A surgical navigation system for navigating a procedure relative to a patient having an electrical isolating portion. The navigation system includes an electrical source (34) and an instrument (52) including a conducting element disposable near the patient. A transmission medium (50) interconnects the electrical source (34) and the instrument (52). An electrical isolator (55) electrically isolates the instrument (52) from the electrical source (34).
