Abstract
An illuminated microsurgical surgical instrument that allows for illumination of the interior of a body cavity during a surgical procedure is provided herein. The surgical instrument may include an elongate tubular member having a distal end for insertion through tissue, the elongate tubular member having an inner diameter, an outer diameter, and a wall thickness. A longitudinal slot extending from the distal end of the elongate tubular member is formed in the elongate tubular member. The surgical instrument further may include an optical fiber extending within the longitudinal slot toward the distal end of the elongate tubular member. The optical fiber may be affixed within the longitudinal slot by an adhesive. The optical fiber may be positioned such that a distal tip thereof is protected from damage by a distal edge of the elongate tubular member during insertion of the instrument into the body cavity.
