Abstract

A test device for an ossicular prosthesis for implantation in the middle ear that includes a first fastening element, a second fastening element and a connecting element that connects the two fastening elements in a sound-conducting manner. Parts of the ossicular prosthesis are made of a material having memory effect and subjected to shape-altering thermal treatment at implantation. The test device also includes a device for determining an optimized power setting or an energy application site for preparing parts of the ossicular prosthesis to be subjected intraoperatively to thermal treatment using a prosthesis mock-up that is identical in design to the ossicular prosthesis in terms of material, geometric shape, and manufacturing method in the parts to be subjected intraoperatively to thermal treatment.

Description

technical field [0001] The present invention relates to a kind of test device with the auditory ossicle prosthesis (Gehoerknoechelchenprothese) that is used to be implanted in the middle ear, and the auditory ossicle prosthesis replaces or supplements at least one joint (Glied) or joint of the human auditory ossicle chain (Gehoerknoechelchenkette) , wherein the ossicle prosthesis has at its one end a first fixation element for mechanical connection with the nodes of the ossicle chain or the tympanic membrane, especially with the incus protrusion (Ambossfortsatz) or with the malleus handle (Hammergriff), and at Its other end place has the second fixation element that is used to be connected with the other joint of auditory ossicle chain or the part of joint or directly with inner ear mechanically and with the connection element that these two fixation elements are interconnected in the mode of sound transmission, and wherein , at least part of the ossicle prosthesis is made of ...
