Abstract

An illumination system to be used within the body of an animal includes a cannula mounted on a handle. On the end of the cannula to be inserted within the animal is a light emitting diode. Either a wired or a wireless system controls the illumination of the LED.

Claims

1. A system for illuminating an interior space within the body of an animal, said system comprising:

a cannula having a first end and a second end;

a hollow handle constructed and arranged for mounting said cannula;

said first end of said cannula being constructed and arranged for insertion into the interior space of the body of the animal;

said second end of said cannula being constructed and arranged for connection to said hollow handle;

said first end of said cannula further including a light emitting diode; and

means for providing an electrical signal for controlling the operation of said light emitting diode.

2. The system as defined in claim 1 wherein said means for providing an electrical signal are located in a console and said electrical signal is conducted to said light emitting diode by wires passing through said hollow handle and said cannula.

3. The system as defined in claim 1 wherein said means for providing an electrical signal is located in a console and said electrical signal is a wireless transmission to a receiver located in said hollow handle, which receiver is connected to said light emitting diode by wires passing through said hollow handle and said cannula.

4. The system as defined in claim 1 wherein the combination of said hollow handle, said cannula, and said light emitting diode are disposable.
