Method and apparatus for positioning a guide relative to a base
First Claim
1. A system for positioning a guide relative to an anatomy comprising:
- a base adapted to be moved relative to the anatomy and thereafter immoveably coupled to the anatomy;
a guide moveably coupled to the base, wherein the guide is configured to move relative to the base at least when the base is immoveably coupled to the anatomy;
a first tracking device coupled to the base and a second tracking device coupled to the guide;
a tracking system that tracks a position of the first tracking device and the second tracking device relative to the anatomy;
a navigation system configured to independently determine a position of both the base and the guide relative to the anatomy based on the position of the first tracking device and the second tracking device and determine if the determined position of the base and the determined position of the guide are about equal to a desired position of the base and a desired position of the guide; and
a display configured to display the desired position of the base and the guide superimposed on an image of the anatomy, a first directional icon superimposed on the image of the anatomy that graphically indicates a desired manipulation of the base required to move the base into the desired position of the base relative to the anatomy and a second directional icon superimposed on the image of the anatomy that graphically indicates a desired manipulation of the guide required to move the guide into the desired position of the guide relative to the anatomy.

Abstract
A system for positioning a guide relative to an anatomy is provided. The system can include a base adapted to be coupled to the anatomy, and a guide that can move relative to the base. The system can include at least one tracking device that can be coupled to the base and the guide, and a tracking system that tracks a position of the tracking device. The system can include a navigation system that determines a position of the base and the guide relative to the anatomy, and whether the position of the base and the guide are in a desired position. The system can include a display, which can display at least one icon superimposed on the image of the anatomy that graphically indicates a manipulation of the guide required to move the guide into the desired position.

12. A method for positioning a guide relative to an anatomy comprising:
-
acquiring a surgical plan for a surgical procedure to be performed on the anatomy that includes a trajectory for an instrument; tracking a first tracking device coupled to a base relative to the anatomy; tracking a second tracking device coupled to a guide relative to the anatomy, the guide movable relative to the base; determining a position of the base and guide relative to the anatomy; comparing the position of the base and the guide relative to the anatomy with a desired base position for the base and a desired guide position for the guide in the surgical plan that enables the guide to guide the instrument along the trajectory; and displaying at least a first icon superimposed onto an image of the anatomy that indicates an amount and direction of a first manipulation required to move the guide into the desired position and at least a second icon superimposed onto an image of the anatomy that indicates an amount and direction of a second manipulation required to move the guide relative to the base into the desired position. - View Dependent Claims (13, 14, 15, 16, 25, 26)

17. A system for positioning a guide relative to an anatomy comprising:
-
a base adapted to be fixedly coupled at a selected location to the anatomy; a guide that moves relative to the base to guide at least one instrument into the anatomy, the guide operable to be coupled to a drive system; a first tracking device coupled to the base; a second tracking device coupled to the guide; a tracking system that tracks a position of the first tracking device and a position of the second device relative to the anatomy; a navigation control module that receives patient image data and surgical plan data, the surgical plan data including a desired base position for the base and a desired guide position for the guide relative to the anatomy; a navigation system that determines a position of the base and the guide relative to the anatomy based on the position of the first tracking device and the second tracking device, and determines if both the position of the base is about equal to the desired base position and if the position of the guide is about equal to the desired guide position; and wherein the navigation control module outputs image data that includes; a first arrow icon superimposed onto the patient image data that graphically represents an amount of movement required to move the base to the desired base position, a second arrow icon superimposed onto the patient image data that graphically represents an amount of rotation and a direction of rotation for the guide to move the guide to the desired guide position, and a third arrow icon superimposed onto the patient image data that graphically represents an amount of translation and a direction of translation for the guide to move the guide to the desired guide position, or combinations thereof. - View Dependent Claims (18, 19, 20)
