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 releasably mounting the retractor to the ring.

Claims

1. 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, one or more LED lights are embedded within the blade and exposed at the upper surface, where the blade surrounding the LED lights is opaque,

one or more electrical connectors that connect the one or more LED lights with a power source;

one or more ridges (80) located on said shaft and located at an end opposite of the blade where each said ridge has a proximal end located toward the middle of the shaft and a distal end located on the shaft end opposite of the blade;

the power source for the LED lights is in communication with the electrical connectors, said power source having one or more slots (41) operationally associated with the one or more ridges (80), each said slot including an open end (86) located on an end closest to a handle (82) and a barrier (88) located on the opposite end of the slot (41);

wherein said shaft (12) is slideably engaged with the slots (41) on the power source by aligning the proximal end of each ridge(s) (80) of the shaft with the open end of each slot(s) (41) of the power source (38) and sliding the power source in a direction opposite of the blade until the proximal end of each ridge lies within each slot and engages the barrier (88) of each slot to releasably secure the shaft to the power source;

wherein each barrier (88) prevents its corresponding ridge (80) and the shaft (12) from exiting the slot (41) while the tissue retractor is in use.

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 are 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 have a lower surface with an integral channel therein, the electrical connectors for the LED lights are housed within the channel, and a closure member covering the channel.

6. The surgical retractor of claim 1 wherein the surgical retractor is autoclavable.

7. The surgical retractor of claim 1 further comprising a pair of re-enforcing wings located at the intersection of the shaft and the blade;

a sleeve which emanates up from the blade, wherein the sleeve is a semi-circular tube-like shape which is hollow and is open at both of its ends such that visualization by the medical professional is not unduly obstructed; and

an insert which is removably and slideably engaged within the sleeve.

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 is adjustable.

10. The surgical retractor of claim 1 wherein the shaft is 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 is concave, flat, convex or round.

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

14. The surgical retractor of claim 13 wherein the camera or cameras are mounted anywhere along the upper surface on the blade either flush with the blade or on a raised surface.

15. A surgical retractor kit comprising a mounting ring, at least one surgical retractor according to claim 1, and a coupler for releasably 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, one or more LED lights facing up from the upper surface, a second surface at an angle to the upper surface, and a sleeve (72) which emanates up from the blade, wherein the sleeve (72) is a semi-circular tube-like shape which is hollow and is open at both of its ends such that visualization by the medical professional is not unduly obstructed;

an insert (70) which is removably and slideably engaged within the sleeve (72);

one or more electrical connectors that connect the one or more LED lights with a power source;

one or more ridges (80) located on said shaft and located at an end opposite of the blade where each said ridge has a proximal end located toward the middle of the shaft and a distal end located on the shaft end opposite of the blade;

the power source for the LED lights is in communication with the electrical connectors, said power source having one or more slots (41) operationally associated with the one or more ridges (80), each said slot including an open end (86) located on an end closest to a handle (82) and a barrier (88) located on the opposite end of the slot (41);

wherein said shaft (12) is slideably engaged with the slots (41) on the power source by aligning the proximal end of each ridge(s) (80) of the shaft with the open end of each slot(s) (41) of the power source (38) and sliding the power source in a direction opposite of the blade until the proximal end of each ridge lies within each slot and engages the barrier (88) of each slot to releasably secure the shaft to the power source;

wherein each barrier (88) prevents its corresponding ridge (80) and the shaft (12) from exiting the slot (41) while the tissue retractor is in use.

17. The surgical retractor of claim 16 further comprising a camera.

18. The surgical retractor of claim 16 wherein the surgical retractor is autoclavable.

19. The surgical retractor of claim 16 where the angle where the shaft and the blade are joined is 5-90°

.

20. The surgical retractor of claim 16 further comprising a pair of re-enforcing wings located at the intersection of the shaft and the blade and further comprising a hook located at an end of said blade.
