Method and device for surgical marking
View Patent ↗A surgical marking pen may include a pen body, a first chamber within the pen body containing at least one powdered dye, a second chamber within the pen body and separated from the first chamber, and a tip in fluid communication with the first chamber or the second chamber. The second container contains a solvent, and the first chamber and the second chamber are selectively placeable into fluid communication with one another. The at least one powdered dye and the solvent, when mixed, form a dye solution which is disposable upon a skin or tissue surface and is able to be visualized simultaneously by a user in ambient light and with a fluorescence imager.
1. A surgical marking pen, comprising:
a pen body;
a first chamber within the pen body containing at least one powdered dye;
a second chamber within the pen body and separated from the first chamber, the second container containing a solvent, the first chamber and the second chamber being selectively placeable into fluid communication with one another; and
a tip in fluid communication with the first chamber or the second chamber,
wherein the at least one powdered dye and the solvent, when mixed, form a dye solution which is disposable upon a skin or tissue surface and is able to be visualized simultaneously by a user in ambient light and with a fluorescence imager.
2. The pen of claim 1 , further comprising a filter between the tip and the first chamber or the second chamber, the filter being configured to homogenize the dye solution and to filter any particulates before the dye solution enters the tip.
3. The pen of claim 2 , wherein the filter comprises a plurality of pores having a size between 5 and 100 microns.
4. The pen of claim 1 , wherein the at least one powdered dye contains one or more dyes visible upon the skin or tissue surface in ambient light.
5. The pen of claim 4 , wherein the at least one powdered dye is selected from the group consisting of gentian violet, bonnie's blue, brilliant green, silver nitrate, aniline dye, and combinations thereof.
6. The pen of claim 1 , wherein the at least one powdered dye comprises one or more invisible fluorescing dyes.
7. The pen of claim 6 , wherein the one or more invisible fluorescing dyes is selected from the group consisting of cyanine, phthalocyanine, oxazine, rhodamine dye, and combinations thereof.
8. The pen of claim 1 , wherein the pen is sterile.
9. The pen of claim 1 , wherein the pen body and/or a cap for receiving the pen body is marked with a scale.
10. A surgical procedure kit, comprising:
the pen as in claim 1 ; and
a volume of intravenous ICG.
11. The kit of claim 10 , further comprising at least one surgical drape.
12. The kit of claim 10 , further comprising a measuring device comprising a scale or a caliper.
13. The kit of claim 10 , further comprising an infrared fluoroscope.
14. The pen of claim 1 , wherein the first chamber is configured to maintain the at least one powdered dye in a shelf-life safe condition until the at least one powdered dye is mixed with the solvent.
15. A surgical marking pen, comprising:
a pen body;
a first chamber within the pen body containing at least one fluorescing dye;
a second chamber within the pen body and separated from the first chamber, the second container containing a solvent, the first chamber and the second chamber being selectively placeable into fluid communication with one another; and
a tip in fluid communication with the first chamber or the second chamber, wherein
the first chamber is configured to maintain the at least one fluorescing dye in a shelf-life safe condition until the at least one fluorescing dye is mixed with the solvent, and
the at least one fluorescing dye and the solvent, when mixed, form a dye solution which is disposable upon a skin or tissue surface and is able to be visualized simultaneously by a user in ambient light and with a fluorescence imager.
16. The pen of claim 15 , further comprising a filter between the tip and the first chamber or the second chamber, the filter being configured to homogenize the dye solution and to filter any particulates before the dye solution enters the tip.
17. The pen of claim 16 , wherein the filter comprises a plurality of pores having a size between 5 and 100 microns.
18. The pen of claim 15 , wherein the at least one fluorescing dye contains one or more dyes visible upon the skin or tissue surface in ambient light.
19. The pen of claim 18 , wherein the one or more dyes visible upon the skin or tissue surface is selected from the group consisting of gentian violet, bonnie's blue, brilliant green, silver nitrate, aniline dye, and combinations thereof.
20. The pen of claim 15 , wherein the at least one fluorescing dye comprises one or more invisible fluorescing dyes.
21. The pen of claim 20 , wherein the one or more invisible fluorescing dyes is selected from the group consisting of cyanine, phthalocyanine, oxazine, rhodamine dye, and combinations thereof.
22. The pen of claim 15 , wherein the pen is sterile.
23. The pen of claim 15 , wherein the pen body and/or a cap for receiving the pen body is marked with a scale.
24. A surgical procedure kit, comprising:
the pen as in claim 15 ; and
a volume of intravenous ICG.
25. The pen of claim 15 , wherein the at least one fluorescing dye is a powdered dye.
26. The pen of claim 15 , wherein the solvent comprises at least one dye visible in ambient light.
27. The pen of claim 1 , wherein the solvent comprises at least one dye visible in ambient light.
