Abstract

Embodiments of claimed subject matter are directed to an illuminating surgical device comprising an array of illuminating elements and an array of louvers to direct light from the individual illuminating elements toward a surgical field.

Claims

1. An illuminating surgical device, comprising:

a plurality of illuminating elements, and a plurality of louvered devices corresponding to the plurality of illuminating elements, the plurality of illuminating elements and the plurality of louvered devices arranged in an array,

the plurality of louvered devices to direct light from individual illuminating elements of the plurality of illuminating elements toward a target surgical field, and

an array of angled reflective surfaces corresponding to the plurality of illuminating elements and the plurality of louvered devices to direct the light from the individual illuminating elements towards the louvers of the plurality of louvered devices.

2. The illuminating surgical device of claim 1, wherein one or more louvers of the plurality of louvered devices is oriented at an angle approximately in the range of 120 degrees to 150 degrees relative to a substantially planar surface of the array.

3. The illuminating surgical device of claim 2, wherein the one or more louvers of the plurality of louvered devices is adjustable between angles of 100 degrees to 160 degrees relative to the substantially planar surface of the array.

4. The illuminating surgical device of claim 1, wherein a top side of one or more louvers of the plurality of louvered devices is coated with a light-absorbing coating to reduce backscattered illumination.

5. The illuminating surgical device of claim 1, wherein at least some illuminating elements of the plurality of illuminating elements are anharmonically spaced relative to one another.

6. The illuminating surgical device of claim 5, wherein beamwidths of at least some illuminating elements of the plurality of illuminating elements are situated so as to overlap with one another.

7. The illuminating surgical device of claim 1, wherein one or more louvers of the plurality of louvered devices is oriented at an angle that minimizes backscatter while maximizing illumination area over the target surgical field.

8. The illuminating surgical device of claim 1, wherein at least some of the reflective surfaces of the array of angled reflective surfaces are oriented at an angle approximately in the range of 25 degrees to 55 degrees relative to a substantially planar surface of the array.

9. The illuminating surgical device of claim 1, wherein illuminating elements of the plurality of illuminating elements utilize light emitting diodes having a color temperature approximately in the range of 6500 degrees Kelvin to 7500 degrees Kelvin.

10. The illuminating surgical device of claim 1, wherein one or more louvers of the plurality of louvered devices comprises a Fresnel-type lens on an underside of the one or more louvers.

11. An illuminating surgical device, comprising:

a plurality of illuminating elements arranged in an array and mounted to a substrate layer;

a reflective layer to having a plurality of reflective surfaces arranged in an array;

a spacing layer to at least partially surround the plurality of illuminating elements and the plurality of reflective surfaces, individual illuminating elements of the plurality of illuminating elements and individual reflective surfaces of the plurality of reflective surfaces being proximate to, and in correspondence with, one another; and

a louvered layer to direct light from individual illuminating elements of the plurality of illuminating elements toward a target surgical field.

12. The illuminating surgical device of claim 11, wherein at least some illuminating elements of the plurality of illuminating elements are arranged anharmonically in a first dimension of the array.

13. The illuminating surgical device of claim 11, wherein the louvered layer comprises louvers oriented approximately in the range of 120 degrees to 150 degrees relative to a substantially planar surface of the array.

14. The illuminating surgical device of claim 11, wherein the louvered layer is slidable so as to permit redirection of illuminating fields.

15. The illuminating surgical device of claim 11, wherein beamwidths of at least some individual illuminating elements of the plurality of illuminating elements overlap with one another.

16. The illuminating surgical device of claim 11, wherein at least some reflective surfaces are oriented at an angle approximately in the range of 30 degrees to 50 degrees relative to a plane of the substrate layer.

17. The illuminating surgical device of claim 11, wherein at least some reflective surfaces of the plurality of reflective surfaces operate to provide approximately lossless reflection of light having a color temperature approximately in the range of 6500 degrees Kelvin to 7500 degrees Kelvin.

18. The illuminating surgical device of claim 11, wherein at least some reflective surfaces of the plurality of reflective surfaces operate to provide approximately lossless reflection of light having a color temperature that includes 3500 degrees Kelvin.

19. The illuminating surgical device of claim 11, wherein a lateral dimension of at least some illuminating elements of the plurality of illuminating elements comprises a length of about one half the lateral dimension of at least some orifices of the spacing layer.
