摘要
A micro surgical lighting instrument includes a hollow needle and a light guide received coaxially within the hollow needle and connected to a light source for transmitting light to a surgical site of a patient. The light guide has a distal end formed with an end face of circular segment shape and defined by a plane oriented orthogonal to the axis of the hollow needle, and a slanted surface adjacent the end face and extending rearwardly at an acute angle, with the slanted surface being lined by a coating for reflection of incident light rays.
