Abstract
In various specific embodiments, a localizer can include a plurality of coil groups, where each coil group includes three coils that are formed around a single center. Each of the three coils can be formed around separate jigs and the jigs can be interconnected to form the coil group. The jigs need not be annular, but may be formed in any appropriate configuration of shape or geometry for forming the final coil group.
Claims21
A system for navigating an instrument, comprising:
- a first coil jig having at least one first coil of conductive material positioned thereon;
- a second coil jig having at least one second coil of conductive material positioned thereon;
- a third coil jig having at least one third coil of conductive material positioned thereon;
- wherein the first coil jig is configured to be assembled with the second coil jig and the second coil jig is configured to be assembled with the third coil jig to form a coil group of the first coil jig, the second coil jig, and the third coil jig,
- wherein the first coil jig includes a main coil receiving portion formed between a first side wall and a second side wall of the first coil jig, and
- wherein the main coil receiving portion has faceted corners configured to receive the at least one first coil of conductive material wrapped on the coil receiving portion and the faceted corners.
A system for navigating an instrument, comprising:
- a transmitter coil array having a coil group, including:
- a first coil portion having a first jig with at least one first coil of conductive material positioned thereon;
- a second coil portion having a second jig having at least one second coil of conductive material positioned thereon;
- a third coil portion having a third jig having at least one third coil of conductive material positioned thereon;
- a tracking device configured to sense a field generated by the transmitter coil array;
- a navigation processor configured to execute instructions to determine a position of the tracking device;
- and
- a display device configured to display a representation at the determined position of the tracking device;
- wherein the first jig includes a coil receiving portion having faceted corners configured to receive the at least one first coil of conductive material wrapped on the coil receiving portion and the faceted corners.
A method of forming and using a localizer for navigating an instrument with a system, comprising:
- forming a coil group by:
- positioning at least one coil of conductive material on a first coil jig;
- positioning at least one coil of conductive material on a second coil jig;
- positioning at least one coil of conductive material on a third coil jig;
- and
- assembling together the first coil jig, the second coil jig, and the third coil jig to form the coil group;
- wherein positioning the at least one coil of conductive material on the first coil jig includes winding the at least one coil of conductive material in a main coil channel of the first coil jig to form a first winding;
- and
- wherein the main coil channel includes faceted corners and the at least one coil of conductive material is wound about the faceted corners.
A system for navigating an instrument, comprising:
- a first coil jig having at least one coil of conductive material positioned thereon;
- wherein the first coil jig includes a main coil receiving portion;
- wherein the main coil receiving portion has faceted corners configured to receive the at least one coil of conductive material wrapped on the coil receiving portion and the faceted corners.
