1. A system to determine information related to a selected device used with a surgical navigation system for navigating a procedure relative to an anatomy, the system comprising:
- an information tag having a memory operable to store, receive, or transmit a selected information;
an information tag reader configured to read the selected information from the memory of the information tag, write the selected information to the memory of the information tag, or combinations thereof at least during an operative procedure;
a surgical instrument associated with the information tag wherein the information tag includes the selected information specific to the surgical instrument;
a navigation system;
a communication system interconnecting the information tag reader and the navigation system wherein the selected information read from the information tag is transmitted to the navigation system;
wherein the information tag reader is further configured to write the selected information to the memory of the information tag during or after a use of the surgical instrument including a change from a previous calibration information including size of the surgical instrument, tip location of the surgical instrument, or orientation of the surgical instrument; and
a display operable to display a representation of the surgical instrument based upon the information read by the information tag reader from the memory of the information tag including the change in calibration information when previously written, wherein the selected information read by the information tag reader from the memory is read during the operative procedure to ensure that the representation of the surgical instrument is correct.

Abstract
A system and apparatus taught to determine the identification and selected information relating to surgical instruments near a reader. The information can be stored on a member operable to transmit the information to a reader at a selected time. The information can be used in a navigation system to assist in navigation of the instrument relative to a patient.

13. A system to determine information related to a selected device used with a surgical navigation system for navigating a procedure relative to an anatomy, the system comprising:
-
an information tag having a member, wherein the information tag is operable to receive and transmit a selected information; an information tag reader operable to read the selected information transmitted from the information tag, write the selected information to the information tag, or combinations thereof; a surgical instrument connected to the information tag, wherein the selected information identifies the surgical instrument; a navigation system having a display device configured to display an icon representing the surgical instrument based on the selected information; a communication system interconnecting the information tag reader and the navigation system wherein the selected information read from the information tag is transmitted to the navigation system; and a navigation system processor included with the navigation system configured to compare the selected information that identifies the instrument read from the information tag that is transmitted to the navigation system and a pre-operative surgical plan accessed by the navigation system processor to determine whether the surgical instrument is appropriate as within the pre-operative surgical plan and that the icon represents the surgical instrument connected to the information tag for display with the display device based at least on the selected information read from the information tag; wherein the pre-operative surgical plan includes surgical plan portions determined and saved prior to an operative procedure including the surgical instrument determined appropriate for at least one surgical plan portion; wherein the navigation system is configured to provide a signal to a user based on the comparison by the navigation system processor; wherein the information tag reader is further configured to write the selected information to the memory of the information tag during or after a use of the surgical instrument including a change from a previous calibration information including size of the surgical instrument, tip location of the surgical instrument, or orientation of the surgical instrument. - View Dependent Claims (14, 15, 16)

17. A system to determine information related to a selected device used with a surgical navigation system for navigating a procedure relative to an anatomy, the system comprising:
-
a navigation system having a localizer, a processor, and a memory system; an information tag member having a memory operable to receive and transmit a selected information; an information tag reader incorporated into the localizer, wherein the information tag reader is configured to at least one of read the selected information from the memory of the information tag member, write the selected information to the memory of the information tag member, or combinations thereof; a surgical item including the information tag member, wherein the selected information includes information specific to the surgical item; a communication system interconnecting the information tag reader and the navigation system wherein the selected information read from the memory of the information tag member is transmitted to the navigation system; and a display operable to display information regarding the surgical item based upon the selected information read by the information tag reader from the memory of the information tag member; wherein the navigation system is configured to determine a representation of the surgical item to be displayed with the display based at least on the read selected information; wherein the memory system stores a surgical plan configured to be recalled by the processor, wherein the surgical plan includes at least a particular surgical item to be used during a surgical procedure; wherein the processor is configured to compare the read selected information to the surgical plan recalled from the memory system and determine that at least the surgical item is appropriate for the planned procedure when compared to the particular surgical item; wherein the information tag reader is further configured to write the selected information to the memory of the information tag during or after a use of the surgical instrument including a change from a previous calibration information including size of the surgical instrument, tip location of the surgical instrument, or orientation of the surgical instrument. - View Dependent Claims (18, 19, 20)
