System, apparatus and methods for recognizing surgical articles left inside patients
System, methods and apparatus related to surgical articles used during surgery. The system, methods and apparatus may include features such as an element/substrate added to surgical articles which enables the recognition by human visualization of the surgical articles when left inside patient bodies when viewed with medical imaging technologies. The element/substrate may include a plurality of three dimensional objects. Alternatively, the element/substrate may comprise a ribbon of radiopaque material having cut-puts or other radiolucent regions which provide image artifacts observable under fluoroscopic imaging.
1. A surgical article comprising:
a sheet of an absorbent fabric material configured to absorb body fluid; and
a first plurality of discreet radiopaque elements distributed over at least one distribution line extending from one edge of the sheet to another edge of the sheet;
wherein the first plurality of discreet radiopaque elements is arranged in a tethered construct which is attached to the sheet of an absorbent fabric material,
wherein the discreet radiopaque elements are secured to a flexible elongate member and the flexible elongate member and the discreet radiopaque elements are formed from the same material filled with a radiopaque filler,
wherein the sheet of absorbent material is configured to be folded and individual ones of the discreet radiopaque elements will align with others of the discreet radiopaque elements to enhance a radiopaque image artifact when the sheet is in its folded configuration, wherein two halves of the sheet are folded at least once over along a fold line and wherein the at least one distribution line crosses over the fold line so that some of the plurality of discreet radiopaque elements are on one side of the fold line and others of the plurality of discreet radiopaque elements are on the other side of the fold line after the sheet of the absorbent fabric material is folded, wherein at least some of the discreet radiopaque elements on one side of the fold line are interspersed between others of the plurality of discreet radiopaque elements on the other side of the fold line after the sheet of the absorbent fabric material is folded, and
wherein at least some of the discreet radiopaque elements on one side of the fold line are interspersed between others of the plurality of discreet radiopaque elements on the other side of the fold line after the sheet of the absorbent fabric material is folded.
2. A surgical article as in claim 1 , wherein the first plurality of discreet radiopaque elements are secured over the flexible elongate member.
3. A surgical article as in claim 1 , wherein the radiopaque elements have a higher radiopacity than that of the elongate member.
4. A surgical article as in claim 1 , wherein the tethered construct is attached to the sheet of an absorbent fabric material by weaving into the fabric, suturing to the fabric, or heat sealing to the fabric.
5. A surgical article as in claim 1 , wherein the sheet comprises a woven surgical sponge material.
6. A surgical article as in claim 1 , wherein some of the discreet radiopaque elements on one side of the fold line stack over or near others of the plurality of discreet radiopaque elements on the other side of the fold line after the sheet of the absorbent fabric material is folded.
7. A surgical article as in claim 1 , wherein the at least one line is oriented at an acute angle relative to the fold line so that the discreet radiopaque elements on one side of the fold line and discreet radiopaque elements on the other side of the fold line are oriented in a V-shape relative to each other after the sheet of the absorbent fabric material is folded.
8. A surgical article as in claim 1 , further comprising a second plurality of discreet radiopaque elements arranged in a tethered construct distributed over at least one additional distribution line extending from one edge of the sheet to another edge of the sheet.
9. A surgical article comprising:
a sheet of an absorbent fabric material configured to be folded and to absorb body fluid in the folded configuration; and
a first plurality of discreet radiopaque elements distributed over at least one distribution line extending from one edge of the sheet to another edge of the sheet,
wherein individual ones of the discreet radiopaque elements will align with others of the discreet radiopaque elements to enhance a radiopaque image artifact when the sheet is in its folded configuration,
wherein the discreet radiopaque elements are secured to a flexible elongate member and the flexible elongate member and the discreet radiopaque elements are formed from the same material filled with a radiopaque filler,
wherein the sheet comprises a woven surgical sponge material,
wherein two halves of the sheet are folded at least once over along a fold line and wherein the at least one distribution line crosses over the fold line so that some of the plurality of discreet radiopaque elements are on one side of the fold line and others of the plurality of discreet radiopaque elements are on the other side of the fold line, and
wherein at least some of the discreet radiopaque elements on one side of the fold line are interspersed between others of the plurality of discreet radiopaque elements on the other side of the fold line.
10. A surgical article as in claim 9 , wherein some of the discreet radiopaque elements on one side of the fold line stack over or near others of the plurality of discreet radiopaque elements on the other side of the fold line after the sheet of the absorbent material is folded.
11. A surgical article as in claim 9 , wherein the at least one distribution line is oriented at an acute angle relative to the fold line so that the discreet radiopaque elements on one side of the fold line and discreet radiopaque elements on the other side of the fold line are oriented in a V-shape relative to each other after the sheet of absorbent material is folded.
12. A surgical article as in claim 9 , further comprising a second plurality of discreet radiopaque elements distributed over at least one additional distribution line extending from one edge of the sheet to another edge of the sheet.
