Button-type RFID tag
An RFID tag that is integrated into button-type, substantially cylindrically-shaped housing with a portion for attaching the tag to an object to be identified through radio frequency identification techniques.
1. A button-type RFID tag comprising:
a substantially cylindrically-shaped structure; and
an RFID transponder circuit secured to the structure, wherein the substantially cylindrically-shaped structure comprises a threaded attachment portion that mates with a complimentary threaded attachment portion at a distal end of a surgical instrument handle, thereby allowing the tag to be detachably affixed to the surgical instrument.
2. The tag according to claim 1 , wherein a memory structure in the RFID transponder circuit the tag stores identification information as well as processing history information for the instrument to which the tag is attached though the life cycle of the instrument.
3. The tag according to claim 1 , wherein the threaded attachment portion comprises a threaded screw member.
4. The tag according to claim 1 , wherein the threaded attachment portion comprises a threaded recess.
5. The tag according to claim 1 , wherein the transponder circuit is formed on a portion of the structure.
6. The tag according to claim 1 , wherein the transponder circuit comprises an antenna, a microprocessor and a digital memory.
7. The tag according to claim 6 , wherein the memory is operable to store identification information for at least one item that the tag is associated with.
8. The tag according to claim 6 , wherein the memory comprises a read only portion and a writable portion.
9. The tag according to claim 6 , wherein the antenna is a wire antenna that circumscribes a portion of the substantially cylindrically-shaped structure.
10. The tag according to claim 1 , wherein at least a portion of the RFID transponder circuit is encapsulated in a protective material.
11. The tag according to claim 10 , wherein the protective housing comprises a material selected from the group consisting of plastic, metal, metal alloy and other pressure resistant material.
12. The tag according to claim 1 , further comprising an outermost shroud portion.
13. The tag according to claim 12 , wherein the outermost shroud portion comprises a recess adapted to receive a turning tool.
14. The tag according to claim 1 , further comprising one or more visual indicia on an outward facing surface of the substantially cylindrically-shaped structure.
15. The tag according to claim 14 , wherein the one or more indicia is selected from the group consisting of a brand owner name, a product name, a category name, a color code, a graphic image, a product identification number, a bar code and combinations thereof.
16. A removable RFID tag comprising:
a substantially cylindrically-shaped structure; and
an RFID circuit secured to the structure, wherein the substantially cylindrically-shaped structure comprises a threaded attachment portion that mates with a complimentary threaded attachment portion at a distal end of a surgical instrument handle, thereby allowing the tag to be removably affixed to the surgical instrument.
17. The tag according to claim 16 , wherein a memory structure in the RFID circuit stores identification information as well as processing history information for the instrument to which the tag is attached though the life cycle of the instrument.
18. The tag according to claim 16 , wherein the threaded attachment portion comprises a threaded screw member.
19. The tag according to claim 16 , wherein the threaded attachment portion comprises a threaded recess.
20. The tag according to claim 16 , wherein the transponder circuit is formed on a portion of the structure.
21. The tag according to claim 16 , wherein the transponder circuit comprises an antenna, a microprocessor and a digital memory.
22. The tag according to claim 21 , wherein the memory is operable to store identification information for at least one item that the tag is associated with.
23. The tag according to claim 21 , wherein the memory comprises a read only portion and a writable portion.
24. The tag according to claim 21 , wherein the antenna is a wire antenna that circumscribes a portion of the substantially cylindrically-shaped structure.
25. The tag according to claim 16 , wherein at least a portion of the RFID transponder circuit is encapsulated in a protective material.
26. The tag according to claim 25 , wherein the protective housing comprises a material selected from the group consisting of plastic, metal, metal alloy and other pressure resistant material.
27. The tag according to claim 16 , further comprising an outermost shroud portion.
28. The tag according to claim 27 , wherein the outermost shroud portion comprises a recess adapted to receive a turning tool.
29. The tag according to claim 16 , further comprising one or more visual indicia on an outward facing surface of the substantially cylindrically-shaped structure.
30. The tag according to claim 29 , wherein the one or more indicia is selected from the group consisting of a brand owner name, a product name, a category name, a color code, a graphic image, a product identification number, a bar code and combinations thereof.
31. A method of rendering a surgical instrument identifiable with an RFID reader comprising:
attaching substantially cylindrically-shaped housing containing an RFID tag circuit to a distal end of a surgical instrument handle using a threaded attachment mechanism aligned along a long axis of the handle;
programming identification information corresponding to the surgical instrument in a memory structure in the RFID tag; and
programming additional processing information in the memory structure when the instrument is processed in or out of an instrument processing facility over the life cycle of the instrument.
