Aillon Tube Bender. One of the most commom problems associated with nasotracheal intubation is observed at a time when the endotracheal tube is about to cross the vocal cords but stops making progress. The tube tends to follow a course which is forward and upward. The trachea's main direction is downward. The solution is to have a tool that not only will control the tip of the tube, but will also bend it down in order to conform with the direction of the trachea. The Aillon forceps tube bender is the solution.
