Abstract

Implantable magnet is fitted wtih one or more metal strips, containing each at least one hole for osteosynthesis screws. Preferably material cross-section of strips is identical in region o fholes and in region between holes.Two magnets may be interconnected by strip firmly in definer spacing. More than two magnets may be interconnected in set. Alignment of magnet poles, in such case is selected in opposition so that, together with external magnets, one or more magnetic circuits may be generated.

Description

Zur Fixation von Epithesen, Toupets und bestimmter Hörgeräte sind Magnetverankerungen beschrieben und empfohlen worden. Dazu werden spezielle Magnete auf oder in den Schädelknochen implantiert. Entsprechende Gegenmagnete oder Metallplatten werden in die externe Vorrichtung eingebracht und zur Fixation der Epithese, des Toupets oder des Hörgerätes genutzt.to Fixation of epitheses, toupees and certain hearing aids are magnetic anchors described and recommended. These are special magnets on or in the skull bones implanted. Corresponding counter magnets or metal plates are introduced into the external device and for fixation of the epithesis, the Toupet or the hearing aid used.

Die einfache und sichere Befestigung der Magnete am Knochen war in der Vergangenheit unbefriedigend. Sie erfolgte durch Weichgewebslappen, Fäden oder selbsthärtenden Kunststoff (Autopolymerisat). Die Befestigung mit Kunststoff war schwierig und zeitaufwändig, die Fixation mit Fäden und Lappen instabil. Deshalb wurden die folgenden Fixationstechniken entwickelt, von denen Ausführungsbeispiele in den anliegenden Graphiken dargestellt sind.The simple and secure attachment of the magnets to the bone was in the Unsatisfactory past. It was done through soft tissue flaps, Threads or self-curing Plastic (autopolymer). The attachment with plastic was difficult and time consuming, the fixation with threads and Lobes unstable. Therefore, the following fixation techniques were used developed, of which embodiments are shown in the accompanying graphics.

Das Prinzip besteht darin, dass ein – meist flach zylinderförmiger – Magnet mit einem, zwei oder mehreren Stegen versehen wird, die Löcher zur Aufnahme von Osteosyntheseschrauben aufweisen. Diese Stege können gebogen und der Knochenoberfläche angepasst werden. Für gleichmäßige Biegeeigenschaften der Stege empfiehlt sich eine geometrische Form, bei welcher der Materialquerschnitt im Bereich der Löcher zur Aufnahme der Schrauben und in den Stegbereichen zwischen den Löchern etwa konstant ist.The The principle is that a - usually flat cylindrical - magnet provided with one, two or more webs, the holes to Have recording of osteosynthesis screws. These webs can be bent and the bone surface be adjusted. For uniform bending properties the webs is recommended a geometric shape in which the Material cross section in the area of the holes for receiving the screws and is approximately constant in the land areas between the holes.

Für bestimmte Indikationen wie beispielsweise einer magnetischen Verankerung von Hörgeräten oder Epithesen empfiehlt sich die Implantation von Doppel- oder Mehrfachmagneten, die bereits durch die Stege fest in definierten Abständen miteinander verbunden sind. Die Ausrichtung der Magnetpole kann bei gegebener Indikation gegensätzlich gewählt werden, so dass zusammen mit den externen Magneten ein oder mehrere magnetische Kreise entstehen.For certain Indications such as magnetic anchoring of Hearing aids or Epithesis recommends the implantation of double or multiple magnets, already firmly connected by the webs at defined intervals are. The orientation of the magnetic poles can be given a given indication antithetical to get voted, so that together with the external magnets one or more magnetic Circles arise.

Ausführungsbeispiele sind in den 1 – 3 dargestellt. 1 zeigt einen einzelnen Magneten (1) mit zwei Stegen (2), in denen sich je ein Loch (3) zur Aufnahme einer Osteosyntheseschraube befindet.Embodiments are in the 1 - 3 shown. 1 shows a single magnet ( 1 ) with two webs ( 2 ), in each of which a hole ( 3 ) is located for receiving an osteosynthesis screw.

2 stellt zwei Magnete (1) dar, die zusätzlich miteinander durch einen Steg (2) verbunden sind. Die Fixation am Knochen erfolgt wie im Ausführungsbeispiel der 1 durch Osteosyntheseschrauben, die durch die Löcher (3) in den Stegen eingebracht werden. 2 puts two magnets ( 1 ), which are additionally interconnected by a bridge ( 2 ) are connected. The fixation on the bone is carried out as in the embodiment of 1 through osteosynthesis screws that pass through the holes ( 3 ) are introduced in the webs.

3 zeigt ein analoges Ausführungsbeispiel mit drei Magneten (1). 3 shows an analogous embodiment with three magnets ( 1 ).
