Illuminated surgical retractor
An illuminated surgical retractor comprising a blade having first and second opposing surfaces, a handle extending in a first direction at an angle from a proximal end of the blade, an illumination assembly comprising at least one direct light source positioned to directly emit light toward a distal end of the blade, wherein the first surface of the blade faces away from the first direction, the illumination assembly abuts the first surface of the blade, and the illumination assembly includes a cover partially enclosing the at least one light source and abutting the first surface of the blade.
1. An illuminated surgical retractor comprising:
a blade having first and second opposing surfaces;
a handle extending in a first direction at an angle from a proximal end of the blade;
an illumination assembly comprising at least one direct light source positioned to directly emit light toward a distal end of the blade, wherein:
the first surface of the blade faces away from the first direction,
the illumination assembly abuts the first surface of the blade, and
the illumination assembly includes a cover abutting the first surface of the blade to partially enclose the at least one direct light source, wherein the direct light source is sandwiched between the cover and the first surface of the blade.
2. The illuminated surgical retractor in accordance with claim 1 , wherein the illumination assembly does not abut the second surface of the blade.
3. The illuminated surgical retractor in accordance with claim 1 , wherein the blade includes a curved portion and a main blade portion, said curved portion forming a joint between the handle and the main blade portion, and wherein the illumination assembly abuts the curved portion of the blade.
4. The illuminated surgical retractor of claim 1 , wherein the illumination assembly further comprises at least one power source and a switch for energizing the direct light source, wherein the cover partially encloses the at least one power source and the switch.
5. The illuminated surgical retractor of claim 4 , wherein the switch comprises one of a removable tab extending from an opening in the cover of the illumination assembly and an electrical switch.
6. The illuminated surgical retractor of claim 1 , wherein the illumination assembly does not include a light pipe.
7. The illuminated surgical retractor of claim 1 , wherein the illumination assembly is non-releasably integrated into the retractor.
8. The illuminated surgical retractor of claim 1 , wherein the blade and the handle are molded from a high strength plastic.
9. The illuminated surgical retractor of claim 1 , wherein a distal end of the blade is wider than the proximal end of the blade.
10. The illuminated surgical retractor of claim 1 , wherein the blade includes a lip at the distal end for retaining tissue.
11. An illuminated surgical retractor comprising:
a blade including a curved portion at a proximal end thereof and a main blade portion extending from the curved portion;
a handle extending at an angle from the proximal end of the blade, said curved portion forming a joint between the handle and the main blade portion;
an illumination assembly comprising at least one direct light source positioned to emit light toward a distal end of the blade,
wherein the illumination assembly includes a cover partially enclosing the at least one direct light source, said cover extending along the curved section of the blade.
12. The illuminated surgical retractor of claim 11 , wherein the direct light source is angled so that substantially all of the light emitted by the direct light source travels to the distal end of the blade.
13. The illuminated surgical retractor of claim 11 , further comprising at least one power source and a switch for energizing the light source.
14. The illuminated surgical retractor of claim 11 , wherein the curved portion includes a recess for accommodating the illumination assembly.
15. The illuminated surgical retractor of claim 11 , wherein the illumination assembly is non-releasably integrated into the retractor.
16. The illuminated surgical retractor of claim 11 , wherein the blade and the handle are formed from high strength plastic.
17. An illuminated surgical retractor comprising:
a blade having first and second opposing surfaces;
a handle extending in a first direction at an angle from a proximal end of the blade;
an illumination assembly comprising at least one direct light source positioned to emit light toward the distal end of the blade, wherein:
the first surface of the blade faces away from the first direction, and
the illumination assembly includes a cover partially enclosing the at least one direct light source and extending along a portion of the first surface of the blade, wherein the direct light source is sandwiched between the cover and the first surface of the blade.
18. The illuminated surgical retractor of claim 17 , wherein the direct light source is angled so that substantially all of the light emitted by the direct light source travels to the distal end of the blade.
19. The illuminated surgical retractor of claim 17 , further comprising at least one power source and a switch for energizing the direct light source, wherein the cover partially encloses the at least one power source and the switch.
20. The illuminated surgical retractor of claim 17 , wherein the illumination assembly is non-releasably integrated into the retractor.
21. The illuminated surgical retractor of claim 17 , wherein the blade and the handle are formed from high strength plastic.
