Abstract
A method and apparatus for identifying a member used in a navigation system. The navigation system can determine the identification of an instrument via an input. The input can be substantially automatic when an instrument is introduced into the navigation system field or assembly.
Claims17
A method of navigating a surgical procedure relative to an anatomy, comprising:
- selecting a surgical instrument with a working portion from a plurality of surgical instruments;
- providing an identification portion with each of the plurality of surgical instruments;
- providing a processor operable to automatically determine an identity of the surgical instrument based on the identification portion;
- automatically determining a position of the working portion of the surgical instrument relative to a reference point based at least in part on the automatically determined identity of the surgical instrument from the plurality of surgical instruments;
- navigating the surgical instrument relative to the anatomy based at least on the automatically determined position of the working portion based at least in part on the automatically determined identity of the surgical instrument from the plurality of surgical instruments;
- displaying an icon representing the automatically determined identity of the surgical instrument relative to image data of the anatomy;
- wherein displaying the icon includes selecting an icon from a plurality of different icons, each of the different icons representing a different selected instrument that can be automatically identified;
- and
- wherein the icon is a display of the surgical instrument;
- providing an electromagnetic field;
- wherein providing the identification portion includes providing a distortion member;
- and
- detecting a distortion in the electromagnetic field produced by the distortion member.

A method of navigating a surgical procedure relative to an anatomy, comprising:
- obtaining image data of the anatomy;
- selecting an instrument from a plurality of instruments;
- automatically determining an identity of the instrument from the plurality of instruments with a processor by evaluating an identification portion of the instrument from the plurality of instruments;
- automatically determining a position of a working portion of the instrument relative to a reference point based at least in part on the automatically determined identity of the instrument from the plurality of instruments;
- navigating the instrument relative to the anatomy at least based on the automatically determined identity of the instrument from the plurality of instruments;
- and
- displaying an icon representing a position of the working portion of the instrument relative to the image data of the anatomy based at least in part on the automatically determined identity of the instrument from the plurality of instruments;
- wherein displaying the icon includes selecting an icon from a plurality of different icons, each of the different icons representing a different instrument that can be automatically identified;
- and
- wherein the icon is a display of the instrument;
- providing an electromagnetic field;
- wherein the identification portion includes a distortion member;
- and
- detecting a distortion in the electromagnetic field produced by the distortion member.

A method of navigating a surgical procedure relative to an anatomy, comprising:
- selecting a working portion of a surgical instrument having an identification portion from a plurality of surgical instruments;
- moving the working portion of the surgical instrument relative to a handle of the selected surgical instrument to create an electromagnetic distortion in an electromagnetic field generated relative to a volume in which the surgical procedure is to occur;
- automatically determining an identity of the surgical instrument with a processor based upon a received signal due to the electromagnetic distortion;
- automatically determining a position of the working portion relative to a reference point based at least in part on the automatically determined identity of the surgical instrument from the plurality of surgical instruments;
- displaying an icon representing the automatically determined identity of the surgical instrument relative to image data;
- wherein displaying the icon includes selecting an icon from a plurality of different icons, each of the different icons representing a different instrument that can be automatically identified;
- and
- wherein the icon is a display of the surgical instrument.
