Surgical instrument system and irrigation sleeve
A surgical instrument system including an endoscope having an elongated housing extending between a proximal instrument end and a distal instrument end. The surgical instrument system may further include an irrigation sleeve having a sleeve body extending between a proximal sleeve end and a distal sleeve end. The irrigation sleeve may further have a first lumen and a second lumen spaced out of fluid communication with the first lumen, the first lumen formed in the sleeve body for receiving at least a portion of the elongated housing of the endoscope with the distal instrument end arranged adjacent to the distal sleeve end. The second lumen may be formed in the sleeve body and extend between a lumen inlet adapted for fluid communication with an irrigation source and a lumen outlet arranged to direct irrigation fluid toward the distal instrument end.
1. A surgical instrument system usable with an irrigation source, the surgical instrument system comprising:
an endoscope having an elongated housing extending between a proximal instrument end and a distal instrument end; and
an irrigation sleeve comprising:
a sleeve body extending between a proximal sleeve end and a distal sleeve end;
a first lumen formed in the sleeve body for receiving at least a portion of the elongated housing of the endoscope with the distal instrument end arranged adjacent to the distal sleeve end; and
a second lumen formed in the sleeve body and extending between a lumen inlet adapted for fluid communication with the irrigation source and a lumen outlet arranged to direct irrigation fluid toward the distal instrument end; and
wherein the second lumen is spaced out of fluid communication with the first lumen.
2. The surgical instrument system as set forth in claim 1 , wherein a proximal lumen region of the second lumen has a larger cross-sectional area than a distal lumen region of the second lumen.
3. The surgical instrument system as set forth in claim 2 , wherein the proximal lumen region of the second lumen has a generally crescent-shaped profile.
4. The surgical instrument system as set forth in claim 2 , wherein the distal lumen region of the second lumen has a profile different from the proximal lumen region.
5. The surgical instrument system as set forth in claim 2 , wherein the distal lumen region of the second lumen has a generally cylindrical profile.
6. The surgical instrument system as set forth in claim 2 , wherein the first lumen is aligned about a first lumen path; and
wherein the proximal lumen region of the second lumen is aligned about a second lumen path spaced from the first lumen path.
7. The surgical instrument system as set forth in claim 6 , wherein the first lumen path is linear.
8. The surgical instrument system as set forth in claim 6 , wherein the second lumen path is radially spaced from the first lumen path.
9. The surgical instrument system as set forth in claim 6 , wherein the second lumen path is linear.
10. The surgical instrument system as set forth in claim 1 , wherein the first lumen has a generally cylindrical profile.
11. The surgical instrument system as set forth in claim 1 , wherein the first lumen has a closed periphery.
12. The surgical instrument system as set forth in claim 1 , wherein the lumen outlet is arranged at the distal sleeve end.
13. An irrigation sleeve for use with a surgical system comprising an irrigation source, a surgical instrument having a housing extending to a distal end, the irrigation sleeve comprising:
a sleeve body extending between a proximal sleeve end and a distal sleeve end;
a first lumen formed in the sleeve body for receiving at least a portion of the surgical instrument; and
a second lumen formed in the sleeve body, spaced from the first lumen, and comprising a proximal lumen region and a distal lumen region, the proximal lumen region extending from a lumen inlet adapted for fluid communication with the irrigation source to a lumen transition, and the distal lumen region extending from the lumen transition to a lumen outlet, the proximal lumen region having a larger cross-sectional area than the distal lumen region taken at the lumen transition; and
wherein the distal lumen region of the second lumen is spaced out of fluid communication with the first lumen.
14. The irrigation sleeve as set forth in claim 13 , wherein a proximal lumen region of the second lumen has a larger cross-sectional area than a distal lumen region of the second lumen.
15. The irrigation sleeve as set forth in claim 13 , wherein the first lumen has a generally cylindrical profile.
16. The irrigation sleeve as set forth in claim 13 , wherein the first lumen has a closed periphery.
17. The irrigation sleeve as set forth in claim 13 , wherein a proximal lumen region of the second lumen has a generally crescent-shaped profile.
18. The irrigation sleeve as set forth in claim 13 , wherein a distal lumen region of the second lumen has a profile different from a proximal lumen region.
19. The irrigation sleeve as set forth in claim 13 , wherein a distal lumen region of the second lumen has a generally cylindrical profile.
20. The irrigation sleeve as set forth in claim 13 , wherein the lumen outlet is arranged between the lumen transition and the distal sleeve end.
