摘要： A total prosthesis for the middle ear, with a prosthesis body, with a first coupling element for connection of the prosthesis to the tympanic membrane or for coupling to the manubrium, and with a second coupling element for connection to the footplate of the stirrup, which second coupling element has a receiving part, connected rigidly to the prosthesis body, and has an insert part with a plug element that can be inserted coaxially, and with a shoe that is connected rigidly to the plug element and that bears on the footplate of the stirrup, is characterized in that the receiving part has an elongate cavity as a receiving opening with a cylindrical bore which extends axially and encloses the full circumference of the plug element and whose inside diameter is greater than the maximum transverse extent of the plug element, which elongate cavity is closed at the end away from the insert part and acts as an end abutment for the plug element, and in that the second coupling element extends axially by at most a third of the axial length of the prosthesis body. In this way, it is easy to produce a desired defined length of the prosthesis, which also remains fixed after surgery, and it is also possible, during surgery, to react to the specific individual situation of the stirrup bone.

摘要： A medical device that is composed of a sterilizable material, is used to create thin cartilage discs, and includes a device body and a cover with a plurality of holding devices, each of which includes a section that with a recess located in the top side of the device body, the recess being entirely or partially enclosed by a delimiting ridge, and being closable via a projection located on the top side of the cover, and in which the lateral delimiting ridge has a guide slot, into which a cutting blade is inserted and guided via an end face of the section and extends, at a distance that differs for each section, parallel to the bottom surface of the particular recess. It is therefore possible to create thin cartilage discs having certain, different thicknesses and a consistent level of quality, even without using the known shims.

摘要： An ossicular prosthesis has a first fastening element for connection to the tympanic membrane or a component of the ossicular chain, a second fastening element for connection to a further component of the ossicular chain, or directly to the inner ear, an elongated connecting element that connects the two fastening elements in a sound-conducting manner and includes an adjusting device for adjusting the axial length of the prosthesis and including at least two partial strands that extend symmetrically to the longitudinal axis of the connecting element, are extendable and/or compressible in the axial direction, are permanently plastically deformable, and are folded into a plurality of loops transversely to the longitudinal axis before being deformed. As a result, a relatively simple design of the adjusting device considerably reduces the number of different prostheses that must be kept on hand, while ensuring that the prosthesis may be optimally adapted for a specific case.

摘要： An auditory ossicle prosthesis (10) which comprises, at one end, a plate-shaped first securing element (11) for bearing on the tympanic membrane or on the footplate of the stirrup, and, at the other end, a second securing element (12) for mechanical connection to the ossicular chain or to the inner ear, and also a connection element (13) that connects the two securing elements so as to conduct sound, wherein the first securing element has a radially inner coupling area (14) for coupling the first securing element to the connection element, and also a plurality of web elements (15) for radial connection of the coupling area to radially outer portions (16) 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.

摘要： A passive ossicular prosthesis includes a first and second fastening element for connection to the tympanic membrane. A connecting element connects the fastening elements in a sound-conducting manner. The connecting element includes a receiving part and an insertion part. The insertion part is inserted into a receiving opening of the receiving part. The receiving part encloses an end section of the insertion part in the manner of a clamp by way of two opposing, parallel legs disposed parallel to a shank axis of the connecting element. The legs have catch devices that fix the enclosed end section discrete spatial positions relative to the shank axis.
