Abstract

Claims (19)

1 . A lighted surgical access system to illuminate internally a body cavity comprising:

an outer ring;

an inner ring;

a sheath having a proximal end connected to the outer ring and a distal end connected the inner ring, the sheath delimiting an access channel extending from the outer ring to the inner ring;

a plastic optical fiber (POF) comprising a POF leader being a proximal portion of the POF and a POF tail being a distal portion of the POF, the POF leader extending beyond the outer ring and connectable to a light source; and

a sleeve connected to a distal portion of the sheath and spaced from the inner ring, the sleeve extending radially around the distal portion of the sheath and the POF tail being positioned within the sleeve.

2 . The lighted surgical access system of claim 1 wherein the POF tail comprises a plurality of cuts.

3 . The lighted surgical access system of claim 2 wherein the plurality of cuts are disposed on a side of the POF tail that faces away from the inner ring and are angled.

4 . The lighted surgical access system of claim 2 wherein the POF tail further comprises a non-transparent material covering a portion of the POF tail.

5 . The lighted surgical access system of claim 4 wherein the POF tail further comprises a reflective material disposed between the non-transparent material and the plurality of cuts.

6 . The lighted surgical access system of claim 1 further comprising a non-transparent material covering the POF leader.

7 . The lighted surgical access system of claim 6 wherein the POF leader further comprises a reflective material disposed between the non-transparent material and the POF leader.

8 . The lighted surgical access system of claim 6 wherein the POF leader comprises a plurality of cuts.

9 . The lighted surgical access system of claim 1 further comprising a reflective material positioned within the sleeve.

10 . The lighted surgical access system of claim 1 wherein the sheath has an inner surface and an outer surface, the sleeve being connected to the outer surface of the sheath and further comprising a reflective material positioned on the inner surface of the sheath.

11 . The lighted surgical access system of claim 1 wherein a distal end of the POF tail has an angled end profile.

12 . The lighted surgical access system of claim 1 further comprising an end cap connected to a distal end of the POF tail.

13 . The lighted surgical access system of claim 12 further comprising a reflective material attached to the end cap.

14 . The lighted surgical access system of claim 1 wherein the sleeve is sealed to the distal portion of the sheath and is impermeable.
