Abstract

A vitrectomy or needle made of a hard resistance metal glass alloy. The wall of the outer tubing or the entire needle can be illuminated when connected to a light source. The instrument, when inserted inside the tissue or the eye, provides illumination, thereby illuminating the surrounding tissue structure and eliminating the need for additional internal or external illumination.

Claims

1. A vitrectomy cutter, comprising:

a needle with a body and a tip, said needle being configured to cut vitreous or tissue and being made from a compound that is transparent to visible light; and

an illumination device connected to said body of said needle, such that said illumination device is capable of providing illumination to an inside portion of an eye through at least one of said tip of said needle and said body of said needle,

wherein the needle includes an opening that is configured to enable cutting of the vitreous or the tissue.

2. The vitrectomy cutter according to claim 1 wherein

the body of the needle is coated with a black material.

3. The vitrectomy cutter according to claim 1 wherein

said compound is one of metal glass and amorphous glass.

4. The vitrectomy cutter according to claim 1 wherein

said illumination device is connected to said body of said needle at a portion of said needle that does not enter the eye.

5. The vitrectomy cutter according to claim 1 wherein

said illumination device is disposed inside said body of said needle.

6. The vitrectomy cutter according to claim 1 wherein

said compound is transparent to visible light from 400-800 nm.

7. The vitrectomy cutter according to claim 1 wherein

said compound is aluminum nitryloxyde.

8. The vitrectomy cutter according to claim 1 wherein

said needle is configured to cut the vitreous or the tissue such that the vitreous or the tissue is capable of being removed.

9. The vitrectomy cutter according to claim 1 wherein

said needle is an outer tube, and said vitrectomy cutter further comprises an inner tube, and

wherein said inner tube is configured to osscilate so as to be capable of cutting the vitreous or the tissue that enters the opening in said outer tube.

10. The vitrectomy cutter according to claim 9 wherein

said inner tube is configured to enable the cut vitreous or the cut tissue to be removed.
