Abstract

An article of manufacture such as surgical steel suspends an elongated antenna radiator above the surface of the steel. The steel surface acts as a ground plane that increases transmission/reception efficiency of the suspended radiator at UHF frequencies. Other embodiments support building reconfigurable surgical trays and the population of same with surgical instruments through a mixed or virtual reality human-machine interface to generate Centerline Gerber/Plot File data for Computer Numerical Control production and Human and/or Robotic Assembly of reconfigurable (or non-reconfigurable) Surgical Trays and the Human and/or Robotic population of Instruments in the Surgical Tray. Example applications include the use of the original Surgical Implant, Surgical Instrument, Surgical Tray, and other related Asset design and manufacturing databases including lot control for pre-populating a digital catalog/database that is used for both Human and Machine Surgical Set assembly and disassembly. Also, this same process may take as input high-resolution imagery and physical attribute capture of Assets to create a next-best-than original facsimile to the original design database and reconstitute a design database from this facsimile

Claims

1. An article of manufacture comprising:

a conductive surface;

a galvanic connection to the conductive surface;

a transponder circuit operatively coupled to the galvanic connection; and

an elongated radio frequency radiator operatively coupled to the transponder circuit, the radio being suspended above the conductive surface to enable the conductive structure to operate as a ground plane for the radiator.

2. The article of claim 1 wherein the conductive surface comprises surgical steel.

3. The article of claim 1 further including an encapsulant that encapsulates the transponder circuit and radiator, the encapsulant providing a dielectric disposed between the conductive surface and the radiator.

4. The article of claim 3 wherein the encapsulant is impervious to the effects of an autoclave, does not carry pathogens, is able to be sterilized, and is substantially transparent to radio frequencies.

5. A method of manufacturing an article comprising:

electrically coupling an RFID die to a conductive surface of an article;

attaching an RF radiator to the RFID die; and

encapsulating the RFID die and the attached RF radiator in an encapsulant to provide sealing, binding and adherence of the RFID die and the RF radiator to the article.

6. The method of claim 5 wherein the article comprises a steel surgical instrument.

7. The method of claim 5 wherein the RFID die includes IEEE 802.15.4 wireless technology.

8. The method of claim 5 wherein the article operates as a ground plane for the RF radiator.

9. The method of claim 5 wherein the encapsulant is impervious to high temperatures of an autoclave.

10. A method of tracking assets comprising:

automatically reading an Advanced Shipping Notice (ASN), confirmed physical contents and condition at the point of the pre-trip loaded inventory, and a continuous monitoring of loaded inventory condition from a mote disposed in a container associated with surgical instruments or other assets; and

providing end-to-end chain of custody tracking of said container,

wherein the mote is configured to withstand an autoclave.

11. The method of claim 10 further including heating the mote by periodically operating it.

12. The method of claim 10 wherein the mote is disposed in or on surgical steel.

13. The method of claim 10 wherein automatically reading is performed at least one of optically, acoustically, magnetically and electromagnetically.

14. The method of claim 10 further including providing a virtual or augmented reality display indicating at least some of the information read from the mote.

15. The method of claim 10 wherein the reading is performed while the container is within an autoclave.

16. A process for manufacturing a surgical tray comprising:

(a) scanning a surgical instrument;

(b) in response to the scanning, adding the surgical instrument as a digital object to a catalog;

(c) using at least one computer, defining a space envelope within a surgical tray for placement of the surgical instrument;

(d) confirming the surgical instrument fits within the defined space envelope; and

(e) using the at least one computer, directing selection of said surgical instrument within other surgical instruments in a surgical tray through a nesting algorithm that maintains alignment with at least some physician preferences, surgical instrument manufacturer requirements, patient attributes and healthcare provider facility characteristics.
