摘要：
A marker for use with a surgical navigation system for tracking the tissue with which the marker is associated. The overall dimensions of the mark is such that it is shaped to be disposed below the skin of the patient in which the marker is implanted. The marker has a stem or a spike that allows the marker to be implanted in hard tissue such as bone. A head, containing navigation system components is located above the stem or spike. Once the procedure is completed the marker is removed from the patient by breaking the head free from the stem Alternatively the head may be rotated to cause the whole of the marker to break free from the bone in which the marker is implanted.
