Abstract:
Otitis media with effusion (OME) arises from accumulation of fluid that occurs within the middle ear space. It is a very common ear disease occurring in adults and children alike when the middle ear is infected or the eustachian tube becomes dysfunctional. The common treatment for OME, when medication as first treatment fails, is to surgically insert a grommet is onto the ear membrane of the patients to discharge the fluid. In this paper, a novel “all-in-one” device allowing office-based grommet insertion in an awake patient with OME is developed and tested. It is a highly integrated and intelligent device comprises of the key components of a mechanical system, a sensing and guidance system and a motion control system. Each system is presented in this paper in details. Finally, the prototype is built and it is tested on mock membranes. Test results show that a success rate of up to 98{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} can be achieved by using this novel surgical device with the Shah type grommet.
