Method and apparatus for surgical navigation
First Claim
1. A navigation system for determining the location of a member relative to an anatomy, comprising:
- a tracking system;
a sensor assembly including;
a sensor an a cap sensor body operable to be sensed by said tracking system; and
a connection portion to interconnect said sensor body with the anatomy having a body connection portion extending from an anatomy engaging portion and a rotation resisting portion.

Abstract
A surgical navigation system for navigating a region of a patient that may include a non-invasive dynamic reference frame and/or fiducial marker, sensor tipped instruments, and isolator circuits. The dynamic reference frame may be placed on the patient in a precise location for guiding the instruments. The dynamic reference frames may be fixedly placed on the patient. Also the dynamic reference frames may be placed to allow generally natural movements of soft tissue relative to the dynamic reference frames. Also methods are provided to determine positions of the dynamic reference frames. Anatomical landmarks may be determined intra-operatively and without access to the anatomical structure.
