Abstract
A surgical implement is disclosed for performing in combination a retracting and illuminating function within body cavities formed during surgery. The retraction function is performed by a blade, which can be segmented for flexible bending, mounted generally at right angles to a support shaft manipulatable by a handle. Miniature lamps present in the blade and powered by small batteries located in the handle perform the illumination function within the body cavity around which the retraction function is simultaneously performed.
