Abstract

A cannula is described having a housing, a first lumen, a second lumen, and a port capable of fluid communication with the first lumen. The second lumen configured to receive fluid from the first lumen and to direct the fluid to a surgical site. A light emitting diode light source is positionable within the housing and configured to direct light through the second lumen to the surgical site.

Claims

1. A cannula system comprising:

a body;

a light source contained within the body;

an infusion port formed in the body for receiving fluids to be delivered to a surgical site; and

a cannula formed with the body and having a lumen for delivering the fluids received through the infusion port and for transmitting light from the light source,

wherein the light source is movable relative to the body for allowing a trocar to be inserted through the cannula to create an incision through which the cannula is inserted.

2. The system of claim 1, further comprising a lens held within the body between the light source and the cannula.

3. The system of claim 2, further including at least one length of fiber optic coupled to the lens and extending at least partially through the cannula.

4. The system of claim 1, further including a power source contained within the body for powering the light source.

5. The system of claim 1, further including a power source connected to and remote from the light source.

6. The system of claim 1, further including a light source-containing portion that is removable relative to the body.

7. The system of claim 1, the body comprising a cap, wherein the light source is contained in the cap.

8. The system of claim 1, wherein the cannula is transparent.

9. The system of claim 1, wherein the light source comprises at least one of a light emitting diode (LED), an organic light emitting diode (OLED), a light bulb, and a lamp.

10. A cannula system comprising:

a housing element having a lumen and a port configured to provide a flow of fluid to the lumen;

a light emitting diode light source positionable within the housing element, the light emitting diode light source configured to direct light through the lumen when disposed within the housing element; and

a trocar, the lumen sized to allow the trocar to pass through the lumen;

wherein a cannula defining the lumen is transparent and is configured to permit light to pass through the cannula defining the lumen from the light emitting diode light source to a surgical site, wherein the lumen is also configured to direct fluid to the surgical site.

11. The cannula system of claim 10, wherein the transparent cannula defining the lumen has a length capable of extending from an outer surface of an eye into an interior of the eye, the length being less than one-half of a diameter of the eye.

12. The cannula system of claim 10, further comprising a lens to direct light through the cannula defining the lumen.

13. The cannula system of claim 12, wherein the lens comprises a plurality of circumferential optical prism elements spaced along a length of the cannula defining the lumen.

14. The cannula system of claim 10, further comprising a power source for the light emitting diode light source.

15. The cannula system of claim 14, wherein the power source comprises at least one battery within the housing element.

16. The cannula system of claim 10, further comprising a phosphorescence material applied to the cannula defining the lumen, wherein light is dispersed from the lumen through the phosphorescence material.
