Document Type and Number:
Japanese Patent JP2002503515
Kind Code:
A
Abstract:
Deafness is often caused by damage to the ossicular chain, which at present is partly or fully replaces by surgical implantation of a corresponding titanium prosthesis. Known versions of this type of middle ear implant consist of a flat coupling body (8) designed to rest against the ear drum, an oblong shank (3) connected to the body for bridging the tympanic cavity and a base (4,11) which is joined to the shank (3) and rests against the base of the implant in the tympanic cavity. Because the depth oft he tympanic cavity varies from patient to patient and measurements become known only during surgery, the length of the implant has to be adjusted very quickly. To be able to do this more simply than is possible with the known implants having a fixed length, the middle ear implant provided by the invention is characterized in that the oblong shank (3) has separation zones (6) to allow for individual adjustment of the shank length to the patient-specific depth of the tympanic cavity during the surgical intervention, and in that the base (4, 11) and/or the flat coupling body (1, 8) are embodied as a slide-on connector part which houses the corresponding end of the shank (3).
