Surgical drape with separable elements
The present disclosure relates to a surgical drape to be used in conjunction with a surgical procedure, and more specifically to a surgical drape that includes one or more of the following: (1) a patient drape for use with a standalone non-draped image acquisition device (requiring circumferential access to the patient); (2) a patient drape for use with a standalone non-draped image acquisition device with image guidance navigation technology; (3) the means to provide temporary sterile coverage of an underlying sterile field; (4) the means to provide sterile separation of at least a portion, if not the entire temporary sterile coverage; (5) the means to provide covering of the undersurface of the operating surface and enclosing any suspended medical devices, wires, cables, tubes, etc; and (6) a single-use disposable outer surgical drape that ensures sterility of a covered surgical apparatus, device, or machine, or an inner drape associated therewith.
1. A surgical draping system, comprising:
an inferior sheet;
a superior sheet, comprising a superior edge and an inferior edge and overlapping an overlap area of the inferior sheet; and
a breakable attachment mechanism, comprising at least one strip of material that interconnects the inferior edge of the superior sheet to the inferior sheet about at least part of the overlap area,
wherein the breakable attachment mechanism is configured:
to be broken, and thereby allow the inferior and superior sheets to be separated and removed, upon application of opposing pulling forces at opposing ends of the surgical draping system, and
in such a way that, when the breakable attachment mechanism is broken and the inferior and superior sheets are separated, no portion of the superior edge of the superior sheet (i) passes over any portion of the inferior sheet without a portion of the inferior edge of the superior sheet intervening therebetween, or (ii) contacts any portion of the inferior sheet.
2. The surgical draping system of claim 1 , wherein the breakable attachment mechanism further comprises one or more adhesive portions of either or both of the inferior sheet and the superior sheet, one or more adhesive elements separate from the inferior and superior sheets, or a combination thereof.
3. The surgical draping system of claim 1 , wherein the breakable attachment mechanism further comprises a hook-and-loop fastener.
4. The surgical draping system of claim 3 , wherein the breakable attachment mechanism further comprises a heat seal.
5. The surgical draping system of claim 1 , wherein the breakable attachment mechanism further comprises an electrostatically attractive element.
6. The surgical draping system of claim 1 , wherein the at least one strip of material is perforated.
7. The surgical draping system of claim 6 , wherein the at least one perforated strip of material comprises a linear perforated strip of plastic film.
8. The surgical draping system of claim 1 , wherein the at least one strip of material interconnects the inferior edge of the superior sheet to the inferior sheet via an adhesive, a heat-seal, or a combination thereof.
9. The surgical draping system of claim 1 , wherein the inferior and superior drapes are sized and configured to cover and maintain the sterility of one of (i) a surgical back table, (ii) a Mayo stand, (iii) a patient or a patient table, (iv) an imaging device, and (v) a surgical robot.
10. A method for maintaining sterility of a sterile surface, comprising:
covering the sterile surface with a surgical draping system, the surgical draping system comprising:
an inferior sheet;
a superior sheet, comprising a superior edge and an inferior edge and overlapping an overlap area of the inferior sheet; and
a breakable attachment mechanism, comprising at least one strip of material that interconnects the inferior edge of the superior sheet to the inferior sheet about at least part of the overlap area,
wherein the breakable attachment mechanism is configured:
to be broken, and thereby allow the inferior and superior sheets to be separated and removed, upon application of opposing pulling forces at opposing ends of the surgical draping system, and
in such a way that, when the breakable attachment mechanism is broken and the inferior and superior sheets are separated, no portion of the superior edge of the superior sheet (i) passes over any portion of the inferior sheet without a portion of the inferior edge of the superior sheet intervening therebetween, or (ii) contacts any portion of the inferior sheet.
11. The method of claim 10 , further comprising:
breaking the breakable attachment mechanism, thereby separating the inferior and superior sheets, by applying opposing pulling forces at opposing ends of the surgical draping system.
12. The method of claim 11 , wherein the breakable attachment mechanism further comprises one or more adhesive portions of either or both of the inferior sheet and the superior sheet, one or more adhesive elements separate from the inferior and superior sheets, or a combination thereof, wherein the magnitude of the opposing pulling forces exceeds the adhesive strength of the one or more adhesive portions, one or more adhesive elements, or combination thereof.
13. The method of claim 11 , wherein the breakable attachment mechanism further comprises a hook-and-loop fastener and the breaking step comprises disengaging the hook-and-loop fastener.
14. The method of claim 11 , wherein the breakable attachment mechanism further comprises a heat seal and the breaking step comprises breaking the heat seal.
15. The method of claim 11 , wherein the breakable attachment mechanism further comprises an electrostatically attractive element and the breaking step comprises disengaging the electrostatically attractive element.
16. The method of claim 10 , wherein the at least one strip of material is perforated.
17. The method of claim 16 , wherein the at least one perforated strip of material comprises a linear perforated strip of plastic film.
18. The method of claim 10 , wherein the at least one perforated strip of material interconnects the inferior edge of the superior sheet to the inferior sheet via an adhesive, a heat-seal, or a combination thereof.
19. The method of claim 10 , wherein the sterile surface is selected from the group consisting of a top surface of a surgical back table, a top surface of a Mayo stand, a surface of a patient, a top surface of a patient table, a surface of an imaging device, and a surface of a surgical robot.
