A surgical device includes a rigid shaft connected between a handle and a head. The head of the surgical device is sized for insertion into an organ such as a vagina, a uterus, a rectum, or an esophagus. The head includes an expansion plate and a door coupled to a central plate. The central plate has a distal end connected to the rigid shaft, an anterior surface, and a recess formed in a posterior side of the central plate that provides a posterior surface opposite the anterior surface. The expansion plate is coupled to and movable relative to the anterior surface of the central plate. The door is coupled disposed within the recess of the central plate and movable relative to the posterior surface of the central plate. The expansion plate is movable independently of the door to allow the head to expand and move the organ.
