Ossicular prosthesis for use in ossicular chain, has fastening unit attached to eardrum or base plate, and another fastening unit connected with parts of limb, where one unit is mechanically stable in assembled condition of puzzle-parts

摘要

The prosthesis (10) has a plate-shaped fastening unit (11) attached to an eardrum or to a stapes base plate, and another fastening unit (12) connected with parts of a limb of an ossicular chain. A connection unit (13) connects the fastening units with one another in a sound-conducting manner, and bar units (15, 15') radially connects a radial inner coupling area (14) with radial outer sections (16, 16') of the unit (11). The area and/or bar units and/or radial sections form common parts of puzzle, where the unit (11) is mechanically stable in an assembled condition of the puzzle-parts.
