Claims (8)

1. Vorrichtung zur Befestigung eines Magneten oder einer elektrischen Spule an den Gehörknöchelchen des menschli­ chen Mittelohrs, dadurch gekennzeichnet, dass sie aus zwei am Magneten (20) oder der elektrischen Spule (20) befe­ stigten Befestigungselementen besteht, von denen das erste Befestigungselement (26) am sogenannten langen Ambossfort­ satz (10) und das zweite Befestigungselement (28) am soge­ nannten Amboss-Steigbügelgelenk (14) der Gehörknöchelchen befestigt wird.1. Device for fastening a magnet or an electrical coil to the ossicles of the human middle ear, characterized in that it consists of two fastening elements on the magnet ( 20 ) or the electrical coil ( 20 ), of which the first fastening element ( 26 ) is attached to the so-called long anvil extension ( 10 ) and the second fastening element ( 28 ) on the so-called anvil stirrup joint ( 14 ) of the ossicles. 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Befestigungselemente (26, 28) aus gebogenen federnden Metallprofilen bestehen.2. Device according to claim 1, characterized in that the fastening elements ( 26 , 28 ) consist of curved resilient metal profiles. 3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, dass die Befestigungselemente (26, 28) eine Öffnung bilden, mit der sie über den langen Ambossfortsatz (10) beziehungs­ weise das Amboss-Steigbügelgelenk (14) geschoben werden können, wobei durch die federnde Konstruktion der Befesti­ gungselemente (26, 28) die Öffnung beim Aufschieben auf den langen Ambossfortsatz (10) beziehungsweise das Amboss- Steigbügelgelenk (14) erweitert und nach dem Aufschieben wieder verengt wird, so dass die Befestigungselemente (26, 28) den Magneten (20) oder die elektrische Spule (20) sicher am langen Ambossfortsatz (10) und am Amboss-Steig­ bügelgelenk (14) befestigen. 3. Device according to claim 2, characterized in that the fastening elements ( 26 , 28 ) form an opening with which they can be pushed over the long anvil extension ( 10 ), as the anvil-stirrup joint ( 14 ), whereby by the resilient construction its mountings supply elements (26, 28) opening when pushed onto the long process of the incus (10) and the anvil stapes joint expanded (14) and is narrowed again after being slid so that the fastener elements (26, 28) the magnet (20) or attach the electrical coil ( 20 ) securely to the long anvil extension ( 10 ) and the anvil stirrup hinge ( 14 ). 4. Vorrichtung nach Anspruch 2 oder 3, dadurch gekennzeich­ net, dass die ersten und zweiten Befestigungselemente (26, 28) in Form von Klammern ausgebildet sind.4. The device according to claim 2 or 3, characterized in that the first and second fastening elements ( 26 , 28 ) are designed in the form of brackets. 5. Vorrichtung nach einem der vorhergehenden Ansprüche, da­ durch gekennzeichnet, dass die Befestigungselemente (26, 28) zusätzlich einen Steg (22, 24) aufweisen, mit dem sie am Magneten (20) oder der elektrischen Spule (20) befes­ tigt sind.5. Device according to one of the preceding claims, characterized in that the fastening elements ( 26 , 28 ) additionally have a web ( 22 , 24 ) with which they are attached to the magnet ( 20 ) or the electrical coil ( 20 ). 6. Vorrichtung nach einem der Ansprüche 2 bis 5, dadurch ge­ kennzeichnet, dass beide Befestigungselemente (26, 28) eine flache Federkennlinie aufweisen.6. Device according to one of claims 2 to 5, characterized in that both fastening elements ( 26 , 28 ) have a flat spring characteristic. 7. Vorrichtung nach einem der vorhergehenden Ansprüche, da­ durch gekennzeichnet, dass die beiden Befestigungselemente (26, 28) aus Titan oder einer Titanlegierung bestehen.7. Device according to one of the preceding claims, characterized in that the two fastening elements ( 26 , 28 ) consist of titanium or a titanium alloy. 8. Vorrichtung nach einem der vorhergehenden Ansprüche, da­ durch gekennzeichnet, dass der Magnet (20) oder die elek­ trische Spule (20) eine Kapselung aus Titan oder einer Titanlegierung aufweisen.8. Device according to one of the preceding claims, characterized in that the magnet ( 20 ) or the elec trical coil ( 20 ) have an encapsulation made of titanium or a titanium alloy.
