Abstract

An illumination probe may include a handle, an optic fiber, a tube, and an illumination source connector. The tube may include a tube distal end and a tube proximal end. The tube may include a tube aperture of the tube distal end. The tube proximal end may be disposed in the handle wherein the tube distal end extends out from a distal end of the handle. The optic fiber may include an optic fiber distal end and an optic fiber proximal end. The optic fiber may be disposed in the illumination source connector, the handle, and the tube wherein the optic fiber distal end is disposed in the tube. The tube aperture may be configured to modify a property of incident illumination light.

Claims

1. An instrument comprising:

a handle having a handle distal end and a handle proximal end;

an illumination source connector having an illumination source connector distal end and an illumination source connector proximal end;

a tube having a tube distal end and a tube proximal end;

an tube aperture of the tube distal end wherein the tube aperture has a generally rectangular geometry having a width in a range of 0.00314 to 0.0320 inches and a height in a range of 0.00314 to 0.0320 inches; and

an optic fiber having an optic fiber distal end and an optic fiber proximal end, the optic fiber disposed in the illumination source connector, the handle, and the tube.

2. The instrument of claim 1 further comprising:

a piston tube having a piston tube distal end and a piston tube proximal end, the piston tube disposed in the handle.

3. The instrument of claim 2 further comprising:

a piston tube guide having a piston tube guide distal end and a piston tube guide proximal end, the piston tube guide disposed in the handle wherein at least a portion of the piston tube is disposed in the piston tube guide.
