Auditory ossicles prosthesis

An auditory ossicles prosthesis, comprising a head plate for abutment against an eardrum;

• and a shaft arranged on said head plate for bridging a tympanic cavity from the eardrum up to a stirrup or a stirrup footplate, said shaft having an end spaced from said head plate and facing the stirrup and being provided at said end with a coupling member, said head plate having a throughgoing passage which extends radially inwardly of a periphery of said head plate and completely through a width of said head plate and is formed for receiving said shaft, so that said shaft can be received in said throughgoing passage and displaced in said throughgoing passage to extend outwardly beyond an outer side of said head plate and to be cut off to be adjusted, said passage being narrowable so that when said shaft is received in said passage and said passage is narrowed, said shaft is immovably fixed in said head plate, said passage having a periphery which is interrupted by a slot, said head plate having a deformable web located in a vicinity of said slot and said passage so that said slot and said passage can be narrowed by caulking of said web.
