Myringotomy training device

About

Background: Myringotomy and tympanostomy tube placement is one of the most common surgical procedures performed in the United States. It is often the first procedure learned by a junior resident in otolaryngology and is commonly not practiced prior to a first attempt on a patient. Novice surgeons are more likely to injure the external auditory canal (ear canal) or take a longer time to complete the surgery as compared to an experienced surgeon. This leads to increased costs and recovery time for the patient. A solution is needed whereby these physicians can practice these microsurgical skills in a manner that is transferable to actual practice.    Technology: The prototype device includes real-time auditory and visual feedback as well as stored feedback about the number of touches and duration of the procedure. It will keep track of a user’s past scores in a game-like manner to encourage continued self-directed improvement that is enjoyable. The ear canals are modular and upgradable so residents can train on various ear canal morphologies. There is a replaceable, disposable cartridge system to imitate the tympanic membrane. It will be held in place between the ear canal and the ossicles (middle ear bones) by magnets that allow the user to snap the cartridge out and replace it with another one between each simulated surgical procedure.    Application: Myringotomy training simulation device for surgical residents   Advantages: 1. Model is anatomically correct 2. Includes real-time auditory and visual feedback as well as stored feedback 3. Ear canals will be modular and upgradeable so residents can train on various ear canal morphologies   Stage of Development: Prototype Provisional Patent Application filed
