Illuminated cannula
First Claim
1. A cannula comprising:
- a hub having a hub distal end and a hub proximal end;
a hub inner lumen of the hub;
a cannula base having a cannula base distal end and a cannula base proximal end, the cannula base fixed to a portion of the hub;
a valve having a valve distal end and a valve proximal end, the valve disposed in the cannula base;
an illumination tube having an illumination tube distal end and an illumination tube proximal end wherein the illumination tube proximal end is disposed in the cannula base;
an optic fiber guide having an optic fiber guide distal end and an optic fiber guide proximal end, the optic fiber guide disposed in the hub inner lumen;
an illumination source connector having an illumination source connector distal end and an illumination source connector proximal end;
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 hub inner lumen, the optic fiber guide, and the cannula base; and
an optic fiber lumen of the cannula base having an optic fiber lumen distal end and an optic fiber lumen proximal end wherein the optic fiber is disposed in the optic fiber lumen; and
a tapered portion of the optic fiber lumen configured to guide the optic fiber distal end out from the optic fiber lumen distal end wherein the optic fiber distal end is disposed flush with the illumination tube proximal end.

Abstract
An illuminated cannula may include an illumination tube, a hub, a cannula base, a valve, an illumination source connector, an optic fiber, and an optic fiber guide. The valve may be disposed in the cannula base. The cannula base may be fixed to the hub. The hub may include a hub aperture. The illumination tube may be disposed in the cannula base. The optic fiber guide may be disposed in the hub. The optic fiber may be disposed in the illumination source connector, the hub, the optic fiber guide, and the cannula base. The optic fiber may be optically coupled to the illumination tube. Illumination light from an illumination source may be configured to transmit through the optic fiber and into the illumination tube.
