Abstract

Claims (37)

1. An illuminated surgical retractor comprising:

a handle;

a blade including:

a curved portion at a proximal end of the blade,

a main blade portion extending from the curved portion, the curved portion being disposed between the handle and the main blade portion, and

a lip at a distal end of the blade; and

an illumination assembly comprising at least one direct light source positioned to emit light toward a distal end of the blade,

wherein the blade surrounds the illumination assembly at least along opposite vertical sides of the illumination assembly,

wherein the illumination assembly includes a cover partially enclosing the at least one direct light source,

wherein said cover extends along the curved portion of the blade, and

wherein the at least one direct light source is positioned closer to the proximal end of the blade than to a distal end of the blade,

wherein the cover is configured to snap fit into a recessed cavity of the blade; and wherein the recessed cavity includes a plurality of slots and the cover includes a plurality of corresponding tabs, each of said tabs being configured to snap fit into a corresponding slot.

2. The illuminated surgical retractor in accordance with claim 1 , wherein the cover includes an open end and the at least one direct light source is positioned within the open end and is angled to direct light along the main blade portion.

3. The illuminated surgical retractor in accordance with claim 1 , wherein the at least one direct light source is positioned proximate to the curved portion.

4. The illuminated surgical retractor in accordance with claim 1 , wherein the blade has a concave surface and wherein the illumination assembly abuts the concave surface of the blade.

5. The illuminated surgical retractor in accordance with claim 1 , wherein the at least one light source is one of a light emitting diode (LED), an incandescent lamp and a fluorescent lamp.

6. The illuminated surgical retractor in accordance with claim 1 , wherein the illumination assembly further includes a power source, and wherein the cover at least partially encloses the power source.

7. The illuminated surgical retractor in accordance with claim 1 , wherein the handle and the blade are molded from a high strength polymer.

8. The illuminated surgical retractor in accordance with claim 1 , wherein the curved portion includes a recessed cavity and the cover is configured to be fitted within the recessed cavity.

9. An illuminated surgical retractor comprising:

a handle;

a blade including:

a curved portion at a proximal end of the blade,

a main blade portion extending from the curved portion, the curved portion being disposed between the handle and the main blade portion, and

a lip at a distal end of the blade; and

an illumination assembly comprising at least one direct light source positioned to emit light toward a distal end of the blade and a cover partially enclosing the at least one direct light source,

wherein the curved portion includes a recessed cavity, and

wherein the cover and at least a portion of the at least one direct light source are configured to be fitted within the recessed cavity, wherein the cover is configured to snap fit into the recessed cavity in the curved portion; and wherein the recessed cavity includes a plurality of slots and the cover includes a plurality of corresponding tabs, each of said tabs being configured to snap fit into a corresponding slot.

10. The illuminated surgical retractor in accordance with claim 9 , wherein the at least one direct light source is proximate to the curved portion.

11. The illuminated surgical retractor in accordance with claim 9 , wherein the cover includes an open end and the at least one direct light source is positioned within the open end and is angled to direct light along the main blade portion.

12. The illuminated surgical retractor in accordance with claim 9 , wherein the at least one light source is one of a light emitting diode (LED), an incandescent lamp and a fluorescent lamp.

13. The illuminated surgical retractor in accordance with claim 9 , wherein the illumination assembly further includes a power source, and wherein the cover at least partially encloses the power source.

14. The illuminated surgical retractor in accordance with claim 9 , wherein the handle and the blade are molded from a high strength polymer.

15. The illuminated surgical retractor in accordance with claim 9 , wherein the at least one direct light source is angled to direct substantially all of the light emitted from the direct light source to the distal end of the blade.

16. The illuminated surgical retractor in accordance with claim 9 , wherein the illumination assembly does not include a light pipe.

17. The illuminated surgical retractor in accordance with claim 1 , wherein the illumination assembly is positioned along a central axis of the blade.

18. The illuminated surgical retractor in accordance with claim 9 , wherein the blade surrounds the illumination assembly at least along opposite vertical sides of the illumination assembly.
