Abstract: A tract expander includes a base having a threaded central hole and a plurality of wings. The base and the wings are connected by a plurality of hinges. Each of the plurality of hinges is connected to the base and to a wing of the plurality of wings so that each wing moves relative to the base. A threaded shaft includes a tip. The tip diameter is larger than the threaded shaft diameter and the threaded shaft is configured to screw into the threaded central hole. The threaded shaft is configured to rotate and move the tip toward the hinged base, causing the tops of the plurality of wings to move away from the threaded shaft.
