Abstract

An illuminated suction apparatus including a hand-held surgical device combining a high-performance non-fiber optic optical waveguide with suction. This device is useful in a wide array of surgical procedures including open and minimally invasive orthopedics.

Claims (17)

1. A hand held illuminated suction device, said device comprising:

a suction tube having an inner surface, an outer surface, a proximal portion, and a distal portion, wherein the proximal portion is configured to be fluidly coupled to a vacuum source, and wherein the distal portion is configured to remove fluid or debris from a surgical field;

a non-fiber optic waveguide coupled to the suction tube, the waveguide configured to deliver light to a surgical field; and

an optical cladding disposed over the waveguide, the optical cladding having an index of refraction that reduces light loss from the waveguide, and

wherein the suction tube is conductive and is configured to conduct electricity.

2. The device of claim 1 , wherein the waveguide comprises microstructures for controlling an output profile of the light delivered from the waveguide to the surgical field.

3. The device of claim 1 , wherein a distal portion of the waveguide comprises an array of lenses integrally formed therein, the array of lenses forming a plurality of spots of light on the surgical field.

4. The device of claim 1 , wherein the waveguide is slidably movable relative to the suction tube, and wherein proximal movement of the waveguide relative to the suction tube increases a spot size and increases diffuseness of the light delivered from the waveguide, and wherein distal movement of the waveguide relative to the suction tube decreases the spot size and increases brightness of the light delivered from the waveguide.

5. The device of claim 1 , wherein the suction tube is malleable and is configured to be bent into a desired shape.

6. The device of claim 1 , wherein the suction tube comprises an electrode for conducting electrical current.

7. The device of claim 1 , wherein the waveguide comprises a concave region for receiving the suction tube thereby reducing overall profile of an assembly of the waveguide and suction tube.

8. The device of claim 1 , further comprising a light source optically coupled with the waveguide.

9. The device of claim 1 , further comprising a suction hole fluidly coupled to the suction tube, the suction hole configured to control suction provided by the suction tube.

10. The device of claim 1 , further comprising a handle coupled with a proximal portion of the waveguide or a proximal portion of the suction tube.

11. The device of claim 1 , wherein the waveguide is formed from a malleable material, and wherein the waveguide is configured to be pulled over the suction tube.

12. The device of claim 1 , wherein an air gap is disposed between the waveguide and the suction tube, the air gap facilitating a reduction in light loss from the waveguide.

13. The device of claim 1 , wherein a non-conductive layer is disposed over the suction tube thereby forming an insulated region that prevents current from exiting from the insulated region.
