Adjustable loop fiber optic illumination device for surgery
View Patent ↗The present disclosure provides an adjustable endoscopic surgical device for illuminating a tissue surface with diffuse and oblique light. In some embodiments, light emanates from the sides of an optical fiber, which is optionally formed at least in part into a loop shape.
1. A surgical device comprising an optical fiber, wherein:
the optical fiber comprises a loop,
a proximal end of the optical fiber is operably coupled to an adjuster that extends from a first point that is coupled to the proximal end of the optical fiber housed within a stem to a second point outside the stem, and
the adjuster is configured to adjust a size associated with the loop.
2. The device of claim 1 , wherein the adjuster comprises a sliding shaft or a sliding cover.
3. The device of claim 1 , wherein the device comprises a first configuration wherein light emanates from the loop, and a second configuration wherein light emanates from a tip of the optical fiber.
4. The device of claim 3 , wherein the device is configured to convert from the first configuration to the second configuration during surgery.
5. The device of claim 1 , wherein the adjuster comprises a lever or a button.
6. The device of claim 1 , wherein the proximal end of the optical fiber terminates within the stem.
7. A method of illuminating ocular tissue, the method comprising:
providing a device according to claim 1 ;
increasing the loop length such that the loop has a diameter larger than an eye or a portion thereof;
placing the loop in proximity to the eye; and
reducing the loop length such that the loop is stationary with respect to the eye.
8. The method of claim 7 , wherein the loop has a diameter larger than a pars plana.
9. The method of claim 7 , wherein the ocular tissue is retinal tissue.
10. The method of claim 7 , wherein a stem housing at least a portion of the optical fiber comprises a flange portion, the method further comprising anchoring the device to the eye using the flange.
11. The method of claim 7 , wherein the method does not include administering a vital dye to the eye.
12. A surgical illumination device comprising:
an optical fiber extending through a lumen and comprising a distal end and a proximal end;
a stem comprising the lumen, wherein the optical fiber and the proximal end are housed within the lumen to form a loop portion defining a loop length; and
an adjuster having a first point operably coupled to the proximal end and extending to a second point outside the stem, wherein movement of the adjuster causes the loop length to change,
wherein the distal end of the optical fiber is configured for coupling to a light source.
13. The device of claim 12 further comprising an optical fiber cable surrounding at least a portion of the optical fiber.
14. The device of claim 12 , wherein the adjuster comprises a sliding shaft or a sliding cover.
15. The device of claim 12 , wherein the stem comprises a flange suitable for anchoring the device in or through ocular tissue.
16. The device of claim 12 , wherein the adjuster comprises a lever or a button.
