    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.
