20080269755 | SYSTEM AND METHOD FOR LOCATING SAW BLADES AND LIKE CUTTING ACCESSORIES WITH A SURGICAL NAVIGATION SYSTEM - A system and method for locating cutting accessories such as saw blades that, when actuated by the complementary driver, move relative to the driver. The saw blade is provided with one or more geometric features. The location of these features is identified by a pointer. The pointer is part of a surgical navigation system used to monitor the position of the driver to which the saw blade is attached. Based on the location of the geometric features, data regarding the head of the saw blade are generated. Thus, the surgical navigation has data indicating the position and orientation of the driver and the position of the head of the cutting accessory relative to the driver. Based on these data, the surgical navigation system generates data indicating the position and orientation of the head of the saw blade or like cutting accessory. | 10-30-2008 |
