    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 its 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, 15′, 15″) for radial connection of the coupling area to radially outer portions (16, 16′, 16″) of the first securing element, is characterized in that the web elements are of such a geometric configuration, and their material so chosen, that the web elements can be easily broken off and the radially outer portions appended to them detached from the first securing element, such that the external diameter of the first securing element is reduced in this area. 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： An ossicle prosthesis has, at on one end, a first fastening element for connection to the tympanic membrane or a component of the ossicular chain, on the other end, a second fastening element for connection to a further component of the ossicular chain, or directly to the inner ear, and a connecting element that connects the two fastening elements in a sound-conducting manner, and it also includes an elongated applicator for transferring the ossicle prosthesis from a sterile packaging to the surgical site and for insertion into the middle ear or the auditory meatus, with a free end extending away from the prosthesis and used for handling purposes, and with an engagement part which is initially fastened to the prosthesis in a non-positive or form-fit manner, or via a material bridge which may be broken off or sheared off, and which may be detached and removed together with the applicator once the prosthesis has been inserted into the ear. This prosthesis may be removed from the sterile packaging and immediately inserted directly into the auditory meatus of the patient, or inserted into the middle ear in a standardized manner, without the use of additional tools, while ensuring that handling during surgery is optimal and tailored to the geometry of the prosthesis and ruling out the possibility of damage occurring via the gripping and transfer of the prosthesis.

    摘要： An ossicle prosthesis (10) includes a first securing element (11) and a second securing element (12), the second securing element connected to a member of the ossicle chain. The ossicle chain ends at the first securing element in a ball joint, which includes two struts (13, 13′) solidly connected to the first securing element (11). The two struts enclose a gaplike space, in which a ball (14) is pivotably supported in two recesses (15), the ball (14) being part of an elongated shaft (16) that connects the first and second securing elements and includes many balls (14, 14′, 14″) adjacent to one another. The elongated shaft is displaceable through the gaplike space between the two struts and through a perforation (17) in the first securing element, where one of the balls snaps between the respective recesses. The gaplike space can be made narrower between the two struts (13, 13′) of the ball joint for fixation of the shaft (16) after the desired length has been adjusted.

    摘要： An ossicle prothesis (10) which includes, at one end, a first fastening element (11) designed as a top plate for mechanical connection with the tympanic membrane and, at the other end, a second fastening element (12) for mechanical connection with a component of the ossicular chain or with the inner ear; it also includes a rotary joint between the two fastening elements, which includes a receiving part (13) in which a rotary element (14)—which is fixedly connected with a longitudinal shank (16) which connects the two fastening elements with each other—is hingedly supported, is characterized by the fact that the receiving part is made of an elastic plastic, the receiving part is rigidly connected with the first fastening element, and the receiving part includes a cavity which is shaped such that, in the installed state, it encloses at least half of the surface of the rotary element. This results in an articulation point which is easy and cost-effective to manufacture and provides the necessary post-operative flexibility and variability of the prosthesis while greatly improving the quality of sound conduction through the prosthesis.
