1. A tracking assembly comprising: a reader comprising: a housing structure that includes a base and a cover; anda scanner positioned in the housing structure for scanning a medical implant;a sterile sheath positioned on the cover; anda sterile drape permanently secured to the sterile sheath, where the sterile drape and the sterile sheath substantially enclose the housing structure, and further wherein the sterile drape includes a drape lower portion that at least partially encloses one or more cords extending from the housing structure. 2. The assembly of claim 1, where the sterile drape extends radially and downwardly from the sterile sheath. 3. The assembly of claim 1, where the sterile drape is removably secured to the sterile sheath. 4. The assembly of claim 1, where the sterile drape is comprised of at least one of elastomer, plastic, rubber, polyethylene, and polypropylene. 5. The assembly of claim 1, further comprising an aperture in the cover to allow optical signals to pass between the scanner and the medical implant. 6. The assembly of claim 5, where the scanner is positioned in the base to form a focal point on a surface of the sterile sheath positioned above the aperture. 7. The assembly of claim 6, where the base further comprises a cavity for at least partially receiving the scanner. 8. The assembly of claim 1, 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 a medical implant upon being scanned by the reader. 9. The assembly of claim 1, where the sterile sheath is formed of a single piece of transparent plastic. 10. A tracking assembly comprising: a reader comprising: a scanner;a scanner mounting structure supporting the scanner;a housing structure that includes a cover with an aperture and a base secured to the cover;a sheath positioned on the cover; anda drape permanently secured to the sterile sheath, where the drape and sheath substantially enclose the housing structure,where the scanner mounting structure is secured to the base, andwhere the scanner and scanner mounting structure are substantially enclosed in the housing structure. 11. The assembly of claim 10, where the sheath is rigid and cylindrical in shape. 12. The assembly of claim 10, where the sheath is cylindrical in shape and includes a locking mechanism. 13. The assembly of claim 10, further including a cavity positioned inside the base, where the scanner is substantially positioned inside the cavity. 14. The assembly of claim 10, where the scanner includes a scanner housing attached to the scanner mounting structure. 15. The assembly of claim 14, where the scanner is capable of scanning 2×2 mm etched identifiers. 16. The assembly of claim 10, where the aperture of the cover corresponds with a focal point of the scanner. 17. The assembly of claim 16, where an optically transparent portion of the sheath is situated in an area above the aperture of the cover. 18. The assembly of claim 14, 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. 19. The assembly of claim 16, where the sterile sheath includes a sterile sheath top surface having at least one of a convex portion and a magnifying portion. 20. The assembly of claim 10, where the sterile sheath is formed of a single piece of transparent plastic. 21. The assembly of claim 10, 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. 22. The assembly of claim 10, where the scanner is connected via a cord to a computer located outside the housing structure. 23. 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; anda housing structure comprising: a cover comprising: an aperture in the cover; and a base secured to the cover, where the base includes a cavity,where the scanner mounting structure is positioned in the cavity of the base, and where the scanner and scanner mounting structure are substantially enclosed in the housing structure;covering the cover with a sterile sheath and further enclosing the reader with a drape secured to the sterile sheath, where the sterile drape and the sterile sheath substantially enclose the housing structure, and further wherein the sterile drape includes a drape lower portion that at least partially encloses one or more cords extending from the housing structure;positioning the reader adjacent to a surgical patient;placing an implant having an identifier over the aperture; andscanning the identifier of the implant to electronically record the implant data.
