First Claim
Patent Images
1. An on tool tracking and guidance device, comprising:
- a housing having a surface for engagement with a surface on a saddle;
a pair of cameras within or coupled to the housing wherein when the housing is coupled to the saddle the pair of cameras are in position to provide an image output having a field of view including at least a portion of an active element of a surgical tool coupled to the saddle;
a display on the housing;
an electronic image processor within or in communication with the housing configured to receive an output from the pair of cameras and perform an image processing operation using at least a portion of the output from the pair of cameras in furtherance of at least one step of a computer assisted surgery procedure; and
a communication element within the housing configured to provide information related to the image processing operation to a component separate from the housing, wherein the communication element is configured to provide information wirelessly, by Bluetooth, by WiFi, or by ultra-wideband technology,wherein the on tool tracking device is configured to determine a computer aided surgery (CAS) processing mode based upon an evaluation of one or more of;
a physical parameter within the surgical field such as a position or a combination of positions of one or more elements tracked in the field through reference frames attached to the one or more elements, a reference frame input, a projected image, a motion detected from a sensor, a motion detection from a calculation, the overall progress of a computer aided surgery procedure, a measured or predicted deviation from a previously prepared computer aided surgery plan wherein the CAS processing mode is selected from one of a number of predefined processing modes including a hover mode, a site approach mode, and an active step mode.

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.
