Problems solved by technology

Sound conduction between the tympanic membrane and the inner ear can often only be achieved to a limited extent with the known ossicle prostheses, because they can only replace the natural anatomy of the ossicles only to a limited extent.

Embodiment Construction

[0041] FIG. 1 shows a perspective view of an inventive ossicle prosthesis 10 with a first spring clip 11 to which a first rod 12 is fastened. The first rod 12 is slightly bent, it does not have to be arranged in a straight line. The rod 12 is materially connected to the first spring clip 11 , which is V-shaped and has a high degree of flexibility. Both the first spring clip 11 and the first bar 12 can be made of a titanium alloy.

[0042] One end of the first rod 12 is a ball 13 , opposite the rod 12 is a first spring clip 11 , the ball 13 is supported in a U-shaped barrel part 14 . Following this U-shaped barrel part 14 is a second rod 15 which transforms into a thick rod 16 . Instead of the thick rod 16 , a further spring clip can be provided on the second rod 15 . The ear ossicle prosthesis 10 according to the present invention is fixed in the middle ear on the incus condyle on one side by the first spring clip 11 or the thick rod or alternatively the other spring clip t...

Abstract

The invention relates to an ossicular prosthesis (40) which replaces or bridges at least one element of the human ossicular chain. The ossicular prosthesis (40) is made of an elastic material or from material having at least articular connection. The inventive prosthesis is characterised in that it is provided with means for adapting the frequency (tuning) for sound conduction in the middle ear, in particular in order to alter lift conditions in the ossicular chain. Sound conduction is considerably improved between the region of the middle ear and the inner ear of the human auditory channel, and enables, in particular, optimal adaptation to the individually different conditions and a tailor-made solution to problems and defects of each patient.

Description

【Technical field】 [0001] The invention relates to an auditory ossicle prosthesis, which replaces or overlaps at least one link in the human auditory ossicle chain, wherein the auditory ossicle prosthesis (10) is made of an elastic material or a material having at least one hinge connection production. 【Background technique】 [0002] Such an ossicle prosthesis is known, for example, from EP 1181907 B2. [0003] Ossicle prostheses are used to transmit sound from the eardrum to the inner ear when the ossicles of the middle ear are completely or partially missing or damaged. Here the ossicle prosthesis has two ends, wherein according to the difference of the specific situation, one end of the ossicle prosthesis is for example fixed on the incus bone process in the human body ossicle chain, and the other end of the ossicle prosthesis is for example It is fixed on the stapes in the auditory ossicle chain of the human body or directly sneaks into the inner ear. [0004] Because ...
