Patent Images
1. An on tool tracking and guidance device, comprising:
- a housing having a surface for releasable engagement with a portion of a hand held surgical tool;
a display on the housing;
a first camera and a second camera in an arrangement within the housing on either side of a central longitudinal axis of the housing whereby each of the first camera and the second camera provide an image output containing an extracorporeal surgical field selected for a computer assisted surgery procedure;
an electronic image processor within the housing configured to receive the image output from each of the first and second cameras and perform an image processing operation using the image output from each of the first and second cameras to provide an image guided navigation output for use in the computer assisted surgery procedure and;
a projector within the housing positioned to provide an output visible within the extracorporeal surgical field containing information related to the image guided navigation output for use in the computer assisted surgery procedure.

Abstract
A number of improvements are provided relating to computer aided surgery utilizing an on tool tracking system. The various improvements relate generally to both the methods used during computer aided surgery and the devices used during such procedures. Other improvements relate to the structure of the tools used during a procedure and how the tools can be controlled using the OTT device. Still other improvements relate to methods of providing feedback during a procedure to improve either the efficiency or quality, or both, for a procedure including the rate of and type of data processed depending upon a CAS mode.
