Abstract

A surgical retractor has a shaft with an integral blade. The shaft and the blade are joined at an angle. The blade has an upper surface. A plurality of LED lights are embedded within the blade and are exposed at the upper surface. The blade surrounding the LED lights is opaque. The retractor may further include a camera mounted on the blade. Also disclosed is a surgical retractor kit including a mounting ring, at least one of the aforementioned surgical retractors, and a coupler for releaseably mounting the retractor to the ring.

Claims

a shaft with an integral blade, the shaft and the blade being joined at an angle, the blade having an upper surface, a plurality of LED lights being embedded within the blade and exposed at the upper surface, the blade surrounding the LED lights being opaque.

2. The surgical retractor of claim 1 wherein each of the LED lights comprises a lens and a LED, the lens being exposed at the upper surface.

3. The surgical retractor of claim 1 wherein each of the LED lights being flush with the upper surface or protruding above the upper surface.

4. The surgical retractor of claim 1 wherein the plurality of LED lights emit at least 90 lumens.

5. The surgical retractor of claim 1 wherein the blade and shaft having a lower surface with an integral channel therein and a closure member covering the channel.

6. The surgical retractor of claim 1 wherein the channel houses electrical connectors for the LED lights.

7. The surgical retractor of claim 1 further comprising a power source for the LED lights in communication with the electrical connectors, and the power source being either carried on the shaft or remote from the shaft.

8. The surgical retractor of claim 1 further comprising a gripping surface on the shaft.

9. The surgical retractor of claim 1 wherein the angle between the shaft and the blade being adjustable.

10. The surgical retractor of claim 1 wherein the shaft being telescoping.

11. The surgical retractor of claim 1 further comprising a second blade facing the first mentioned blade and being moveable to and from the previous mentioned blade.

12. The surgical retractor of claim 1 wherein the upper surface being concave.

13. The surgical retractor of claim 1 further comprising a camera being mounted on the blade.

14. The surgical retractor of claim 13 wherein the camera being mounted in a second surface adjacent to the upper surface.

15. A surgical retractor kit comprising a mounting ring, at least one surgical retractor according to claim 1, and a coupler for releaseably mounting the retractor to the ring.

16. A surgical retractor comprising:

a shaft with an integral blade, the shaft and the blade being joined at an angle, the blade having an upper surface, a plurality of lights facing up from the upper surface, a second surface at an angle to the upper surface, and a camera disposed in the second surface, wherein the camera faces down the blade and away from the upper surface.

17. The surgical retractor of claim 16 where the camera being a CCD camera.

18. The surgical retractor of claim 16 where the lights being LED lights.
