A vaginal cervical retractor used to maneuver and visualize the uterus during various medical examinations and procedures would include an inner tube provided with a movable pair of plastic caps designed to be inserted into the uterine cavity. A cervical cap is secured to this tube to insure that the tube would not extend beyond a certain distance into the uterus. A hollow outer shaft is provided into which the inner tube can be inserted.
