Abstract
An illuminated microsurgical instrument is provided herein that includes a microsurgical instrument having a tubular member arranged to treat patient tissue at a surgical site, the tubular member having a distal tip, an inner surface, and an outer surface. The inner surface defines a lumen. The outer surface has a notch formed therein. The illuminated microsurgical instrument further includes an optical fiber arranged to deliver light to the surgical site. The optical fiber includes a proximal end arranged to receive a light beam from a light source and also includes a curved distal end arranged to emit light adjacent to the distal tip. A portion of the curved distal end is positioned within the notch and curves away from the tubular member.
