Abstract
A surgical tool for mounting a trackable target to a human bone, suitable for fixation to a human femur. The tool includes a removable bone clamp and a releasable coupling member which is integrated with the removable bone clamp. The releasable coupling member is arranged to mate with a compatible coupling member mounted on the trackable target to establish a predetermined spatial relationship between the bone clamp and trackable target. The releasable and compatible coupling members form a releasable connection which is mechanically constrained to re-engage only in a re-engaged position that accurately recaptures the predetermined spatial relationship.
