Abstract

The apparatus and method is provided that employs a “radiopaque” object to count and account for surgical sponges in an operating room. A radiopaque object is embedded in surgical sponges so that a scanning device can detect and count a large number of the sponges within a container. The container is designed to minimize contact with the sponges by humans. In addition, a surgical team can insure that no surgical sponge is left in a patient without performing the messy and time-consuming job of individually counting sponges as they are entered and disposed of from the surgical site.

Claims

1. A detectable surgical article, comprising:

material capable of at least one of absorbing fluids within a body and packing bodily structures; and

a radiopaque object affixed to said material, wherein the radiopaque object produces a non-polygon-shaped radiographically imaged profile when the radiopaque object is radiographically scanned while orientated in at least one position and wherein said radiographically imaged profile exhibits a radiographically imaged contrast throughout an entire area encompassed by a perimeter of the radiographically imaged profile when the radiopaque object is radiographically scanned while orientated in any position.

2. The detectable surgical article of claim 1, wherein a detectable characteristic of the radiopaque object corresponds to a particular configuration of said material.

3. The detectable surgical article of claim 2, wherein the detectable characteristic of the radiopaque object is related to at least one of size, shape, outside dimension and material of the radiopaque object.

4. The detectable surgical article of claim 1, wherein the radiopaque object is spherical.

5. The detectable surgical article of claim 1, wherein the radiopaque object is non-spherical.

6. The detectable surgical article of claim 1, wherein the radiopaque object is at least partially made of metal.

7. The detectable surgical article of claim 1, wherein the radiopaque object includes a non-metallic radiopaque substance.

8. The detectable surgical article of claim 7, wherein the non-metallic radiopaque substance is barium sulfate.

18. The detectable surgical article of claim 1 wherein the radiopaque object is substantially non-activating when exposed to radio frequencies.

19. The detectable surgical article of claim 1, further comprising:

attachment means engaged between the radiopaque object and said material.

9. A method of counting surgical articles, comprising:

receiving a plurality of articles capable of at least one of absorbing fluids within a body and packing bodily structures, wherein each one of said articles includes a radiopaque object;

radiographically scanning the plurality of articles simultaneously, wherein the radiopaque object of each one of said articles produces a radiographically imaged profile dependent upon a shape of the radiopaque object during said scanning; and

determining the number of radiopaque objects at least partially dependent upon the radiographically imaged profile corresponding to each one of said radiopaque objects.

10. The method of claim 9, wherein:

the plurality of articles includes articles of at least two different configurations; and

the radiographically imaged profile of each one of said articles corresponds to a particular configuration of a respective one of said articles.

11. The method of claim 9, further comprising:

determining an as-scanned weight of said articles; and

determining an amount of fluid absorbed by said articles by subtracting an as-manufactured weight of said articles from the as-scanned weight of said articles.

20. The method of claim 9 wherein the radiopaque object of each one of said articles produces a non-polygon-shaped radiographically imaged profile when the radiopaque object is radiographically scanned while orientated in at least one position and wherein said radiographically imaged profile exhibits a radiographically imaged contrast throughout an entire area encompassed by a perimeter of the radiographically imaged profile when the radiopaque object is radiographically scanned while orientated in any position.

12. A product line of detectable surgical articles, comprising:

a plurality of articles each including a material capable of at least one of absorbing fluids within a body and packing bodily structures and a spherical shaped radiopaque object affixed to said material, wherein the radiopaque object of each one of said articles produces a respective radiographically imaged profile when radiographically scanned while orientated in any position, wherein a first portion of said articles has a first as-manufactured physical configuration and a second portion of said articles has a second as-manufactured physical configuration different than the first as-manufactured physical configuration, and wherein the radiographically imaged profile of the radiopaque object of each one of said articles corresponds to said configuration of a respective one of said articles.

13. The product line of claim 12, wherein:

the first as-manufactured physical configuration corresponds to said material being at least one of a first type, a first size and a first shape; and

the second as-manufactured physical configuration corresponds to said material being at least one of a second type, a second size and a second shape.

14. The product line of claim 13, wherein said radiographically imaged profile of the radiopaque object of each one of said articles is related to at least one of size, shape, outside dimensions and material.

15. The product line of claim 12, wherein said radiographically imaged profile of the radiopaque object of each one of said articles relates to at least one of size, shape, outside dimension and material.

16. The product line of claim 12, wherein the radiopaque object of each one of said articles is at least partially made of metal.

17. The product line of claim 12, wherein the radiopaque object of each one of said articles includes a non-metallic radiopaque substance.

21. A system for counting surgical articles, comprising:

means for receiving a plurality of article capable of at least one of absorbing fluids within a body and packing bodily structures;

means for scanning said articles simultaneously, wherein a radiopaque object of each one of said articles produces a radiographically imaged profile dependent upon a shape of the radiopaque object during said scanning; and

means for determining the number of radiopaque objects at least partially dependent upon the radiographically imaged profile corresponding to each one of said radiopaque objects.

22. The system of claim 21, wherein:

the plurality of articles includes articles of at least two different configurations; and

the radiographically imaged profile of each one of said articles corresponds to a particular configuration of a respective one of said articles.

23. The system of claim 21, further comprising:

means for determining an as-scanned weight of said articles; and

means for determining an amount of fluid absorbed by said articles by subtracting an as-manufactured weigh of said articles from the as-scanned weight of said articles.

24. The system of claim 21 wherein the radiopaque object of each one of said articles is substantially non-activating when exposed to radio frequencies.
