Abstract

An assembly and method for tracking implant devices within a sterile field, the assembly comprising a reader that includes a housing structure with a base and a cover, a scanner having a scanner housing, where the scanner housing is at least partially positioned in a cavity provided in the base; and an aperture provided in the cover, where the cover is configured to receive a transparent sterile sheath to at least partially encase the cover.

Claims

1. A tracking assembly comprising:

a reader comprising;

a housing structure that includes a base and a cover;

a scanner having a scanner housing, where the scanner housing is at least partially positioned in a cavity provided in the base;

an aperture provided in the cover;

a disposable rigid plastic transparent sterile sheath positioned over the cover; and

a medical drape attached to a side wall of the transparent sterile sheath.

2. The assembly of claim 1, where the transparent sterile sheath includes a generally circular sheath top surface and cylindrical sheath side wall that extends perpendicularly downward from the sheath top surface towards a sheath bottom surface.

3. The assembly of claim 1, where the medical drape extends radially and downwardly from the transparent sterile sheath.

4. The assembly of claim 1, where the medical drape is removably secured to the transparent sterile sheath by an elastic band.

5. The assembly of claim 1, where the medical drape is permanently secured to the transparent sterile sheath.

6. The assembly of claim 1, where the combination of the transparent sterile sheath and the medical drape substantially cover the housing structure to substantially limit exposure of the housing structure to the atmosphere.

7. The assembly of claim 1, where the scanner is positioned in the base to form a focal point on a top surface of the transparent sterile sheath above the aperture.

8. The assembly of claim 7, where the reader further comprises a scanner mounting structure supporting the scanner wherein the scanner mounting structure is positioned substantially in the cavity and secured to the base.

9. The assembly of claim 7, where the scanner is in communication with a computer device located apart from the reader, where the computer device is capable of receiving and storing information obtained from the identifier upon being scanned by the reader.

10. The assembly of claim 9, where the scanner is capable of scanning 2×

2 mm etched identifiers.

11. A tracking assembly comprising:

a reader comprising;

a scanner;

a scanner mounting structure supporting the scanner; and

a housing structure that includes a cover with an aperture and a base secured to the cover,

where the housing structure is configured to receive one or more coverings to at least partially enclose the housing structure,

where the one or more coverings include a sterile sheath positioned over the cover, and a medical drape attached to the sterile sheath,

where the scanner mounting structure is secured to the base, and

where the scanner and scanner mounting structure are substantially enclosed in the housing structure.

12. The assembly of claim 11, where the medical drape is permanently secured to the sterile sheath.

13. The assembly of claim 11, further including a cavity positioned inside the base, where the scanner is substantially positioned inside the cavity.

14. The assembly of claim 13, where the scanner includes a scanner housing attached to the scanner mounting structure.

15. The assembly of claim 11, where the sterile sheath is at least partially transparent.

16. The assembly of claim 15, where the sterile sheath includes a magnifying portion.

17. The assembly of claim 15, where the scanner is capable of scanning 2×

2 mm etched identifiers.

18. The assembly of claim 15, where the aperture of the cover corresponds with a focal point of the scanner.

19. The assembly of claim 18, where the scanner housing has a lens secured thereto, where the lens includes a front surface, where the front surface is situated between about 3 inches to about 5 inches from the aperture of the cover.

20. The assembly of claim 18, where the sterile sheath includes at least one of a convex portion and a magnifying portion.

21. The assembly of claim 11, where the sterile sheath is formed of a single piece of partially or completely transparent plastic.

22. The assembly of claim 21, where the sterile sheath is disposed of after identifiers have been received for all the medical implants implanted in a single patient during an operation.

23. The assembly of claim 11, where the sterile sheath includes a sheath side wall having at least one radial pin slot sized and positioned to interlock with at least one radial pin extending from the cover, to allow for temporary engagement therebetween.

24. The assembly of claim 15, where the scanner is connected via a cord to a computer located outside the housing structure.

25. A method of using a tracking assembly comprising the steps of:

providing a tracking assembly comprising;

a reader comprising;

a scanner;

a scanner mounting structure supporting the scanner; and

a housing structure that includes an aperture,

where the scanner mounting structure is positioned in a cavity of the housing structure, and

where the scanner and scanner mounting structure are substantially enclosed in the housing structure;

covering at least a portion of the housing structure with a transparent sterile sheath and a medical drape secured to the transparent sterile sheath;

placing an implant having an identifier over the aperture; and

scanning the identifier of the implant to electronically record the implant data.

26. The method of claim 25, further including disposing of the medical drape and the transparent sterile sheath after a single use during a medical procedure.

27. The method of claim 25, where the identifier on the implant is an etched 1.4×

1.4 mm matrix containing data regarding the implant.

28. The method of claim 25, further including sensing an implant having an identifier, when the implant is positioned above the aperture and automatically obtaining a scan of the identifier.
