Abstract

Disclosed is a surgical navigation system for tracking an instrument relative to a patient. The system can track a portion of the patient, an instrument, and/or both relative to image data, a coordinate system, an atlas, a morphed atlas, or combinations thereof. The system can include a tracking device on the instrument to provide six degree of freedom information regarding the location of the instrument.

Claims

1. A method of providing an instrument for a procedure, comprising:

providing a tracking device for the instrument having a longitudinal axis, by;

providing a first tracking portion wrapped a first length around the longitudinal axis for a first distance, wherein the wrapped first length includes a plurality of turns and each turn is formed at a first winding angle relative to the longitudinal axis to define a first wrap axis; and

providing a second tracking portion wrapped a second length around the longitudinal axis for a second distance, wherein the wrapped second length includes a plurality of turns and each turn of the second material is formed at a second winding angle relative to the longitudinal axis to define a second wrap axis;

providing the first tracking portion and the second tracking portion configured to be in communication with a navigation system.

2. The method of claim 1, further comprising:

providing the first tracking portion formed of a first material; and

providing the second tracking portion to be formed of a second material.

4. The method of claim 1, further comprising:

providing the first tracking portion spaced a distance from the second tracking portion along the longitudinal axis.

5. The method of claim 1, further comprising:

providing the first tracking portion to be formed between the second tracking portion and an outer wall of the instrument.

6. The method of claim 1, further comprising:

providing the first tracking portion and the second tacking portion on the instrument to generate all of a first navigation vector and a second navigation vector to intersect near a single point in a single plane.

7. The method of claim 1, further comprising:

determining with the navigation system;

a first navigation vector of the first tracking portion and a second navigation vector of the second tracking portion; and

a location information for the tracking device based on the determined first navigation vector and the determined second navigation vector.

8. The method of claim 1, further comprising:

providing a third tracking portion wrapped a third length around the longitudinal axis for a third length, wherein the wrapped third length includes a plurality of turns and each turn is formed at a third winding angle relative to the longitudinal axis.

9. The method of claim 1, further comprising:

providing a plurality of the tracking devices; and

providing the instrument to be flexible;

wherein a first tracking device of the plurality of tracking devices is configured to track a first portion of the instrument and a second tracking device of the plurality of the plurality of tracking devices is configured to track a second portion of the instrument.

3. The method of claim 3, wherein the first material and the second material are the same material and a conductive material.

10. An instrument, comprising:

a tracking device formed around a longitudinal axis of the instrument, including;

a first tracking portion wrapped a first length around the longitudinal axis for a first distance, wherein the wrapped first length includes a plurality of turns and each turn is formed at a first winding angle relative to the longitudinal axis to define a first wrap axis; and

a second tracking portion wrapped a second length around the longitudinal axis for a second distance, wherein the wrapped second length includes a plurality of turns and each turn is formed at a second winding angle relative to the longitudinal axis to define a second wrap axis;

wherein the first tracking portion is configured to define a first navigation vector and the second tracking portion is configured to define a second navigation vector.

11. The instrument of claim 10, wherein the first tracking portion is formed of a first material and the second tracking portion is formed of a second material.

12. The instrument of claim 10, wherein the first tracking portion is spaced a distance along the longitudinal axis from the second tracking portion.

13. The instrument of claim 10, wherein the first tracking portion is positioned between the second tracking portion and an exterior wall of the instrument.

14. The system of claim 10, wherein at least one of the first winding angle and the second winding angle is about 40 degrees to about 50 degrees.

15. The system of claim 10, further comprising:

an elongated member as the instrument extending along the longitudinal axis.

16. The system of claim 14, further comprising:

a tracking system localizer having a system to induce a voltage in the first tracking portion and the second tracking portion;

a processor to receive a signal from the first tracking portion and the second tracking portion to compute a location of the first tracking portion and the second tracking portion based on the first navigation vector and the second navigation vector.

17. A trackable instrument, comprising:

an instrument having at least an elongated portion extending along a longitudinal axis;

a tracking device, including;

a first tracking portion of a first material having a first plurality of turns around the elongated portion, wherein each turn of the first plurality of turns is formed at a first winding angle relative to the longitudinal axis; and

a second tracking portion of a second material having a second plurality of turns around the elongated portion, wherein each turn of the second plurality of turns is formed at a second winding angle relative to the longitudinal axis, wherein the second winding angle is different from the first winding angle;

wherein the first tracking portion defines a first navigation vector and the second tracking portion defines a second navigation vector to determine an orientation of at least a first section of the elongated portion.

18. The trackable instrument of claim 17, further comprising:

a third tracking portion of a third material having a third plurality of turns around the elongated portion, wherein each turn of the third plurality of turns is formed at a third winding angle relative to the longitudinal axis.

19. The trackable instrument of claim 18, wherein the instrument includes a working portion configured to act at a selected angle relative to the longitudinal axis.

20. The trackable instrument of claim 19, wherein the working portion is selected from a group consisting of an opening, an ablation needle, a biopsy window, an ablation portion, or a sensing portion.

21. The trackable instrument of claim 19, further comprising:

a display device configured to display an icon representative of an orientation of the working portion illustrated relative to an environment in which the elongated portion is placed.

22. The trackable instrument of claim 21, further comprising:

a tracking system localizer having a system to induce a voltage in the first tracking portion and the second tracking portion to determine a position of the first navigation vector and the second navigation vector.
