Abstract
An auditory ossicle prosthesis () which comprises, at one end, a plate-shaped first securing element () for bearing on the tympanic membrane or on the footplate of the stirrup, and, at the other end, a second securing element () for mechanical connection to the ossicular chain or to the inner ear, and also a connection element () that connects the two securing elements so as to conduct sound, wherein the first securing element has a radially inner coupling area () for coupling the first securing element to the connection element, and also a plurality of web elements () for radial connection of the coupling area to radially outer portions () of the first securing element, is characterized in that the coupling area, the web elements and the radially outer portions are of such a geometric configuration, and their material so chosen, that a plastic deformation is effected by stretching or pushing together in the plane of the plate of the first securing element, by means of which plastic deformation the external diameter of the first securing element is permanently increased or reduced. This means that the number of different prostheses to be kept ready during an operation can be reduced to a single standard prosthesis, without losing the possibility of optimal adaptation of the prosthesis to the specific case of use.
