Abstract

Provided herein is an illuminated microsurgical instrument system and an illuminated microsurgical instrument. In one implementation, the system includes a microsurgical instrument having a distally projecting tubular member arranged to perform a medical procedure at an interventional site. The tubular member has a distal tip and an outer surface, the outer surface having a flat surface formed therein. The instrument includes a sheath member surrounding a portion of the tubular member and extending toward the distal tip of the tubular member and an optical fiber extending along a length of the flat surface between the tubular member and the sheath member. The instrument may further include a slack chamber, collar structure, and fiber guard member to support and guide the optical fiber to the distal tip.
