发明名称 Organ retractors
摘要 An improved organ retractor includes an elongate handle and a rigid stem extending from one end of the elongate handle. A hollow sleeve is positioned around the stem and is axially slidable along the stem from a retracted position partly inside of said handle to an extended position. The sleeve is bifurcated or divided axially in half adjacent a distal end thereof to define two opposed elongate resilient fingers. The distal ends of each of the fingers are movable from a closed position wherein those distal ends are substantially adjacent each other surrounding the rigid stem to an open position wherein the distal ends are spaced from each other. A connector arm is positioned between each of the fingers and the rigid stem. The connector arms move the fingers to an open position when the stem is in one of the retracted and extended positions and move the fingers to a closed position when the stem is in the other of the retracted and extended positions. In a second embodiment of the invention, the opposed resilient fingers include a plurality of digits serially pivotally mounted to each other along the length of each finger.
