Abstract
A computer assisted surgery system for accurate positioning of a drill bit into a body part. The system includes a drill guide and a drill with attached localizing emitters whose poses are determined by a localizing device. The drill bit is attached to the drill and the location of the tip of the drill bit is determined during a calibration step. During drilling, the drill bit is inserted through the bore of the drill guide and the pose of the drill bit is calculated from measured position data of both the drill guide and drill. A graphic representation of the drill bit is then displayed on a monitor screen in an appropriate position relative to stored images or other surgical instruments.
