Description

Die vorliegende Erfindung betrifft eine Schiene zui Führung und Heilung fiaktunewer Knochen nut einem den Knochen in seiner Normallagc fixierenden Schienenkörper.The present invention relates to a rail zui Guidance and healing fiaktunewer bone nut a splint body that fixes the bone in its normal position.

Aus der britischen Patentschrift 322 458 ist eine elektromedizinische I.mpfangsvorriclitung für clek tromagnetische Schwingungen bekannt, die au-, einem stabförmigen festen Körper besteht, der eine Induktionsspule tragt, deren Wicklungsdrahtenden in unterschiedliche Raumrichtungen weisen.From British patent specification 322 458 an electromedical I.mpfangsvorriclitung for clek tromagnetic vibrations known, which au-, consists of a rod-shaped solid body carrying an induction coil, the winding wire ends in show different spatial directions.

Aus der I'SA.-Patentschrift 3 357 434 ist ein in den menschlichen Körper implanticrbares Geluiise bekannt, das eine Induktionsspule trägt, deren Wicklungsdrahtenden eine metallische Oberfläche aufweisen und vom implantierbaren Gehäuse abstehen sowie nach Art von Nadelkontakten ausgebildet sind, das einen Kondensator aufweist, der in Verbindung mit der Induktionsspule einen elektrischen Schwingkreis bildet, und in dessen Bereich ein an die Induktionsspule angeschlossener Gleichrichter vorhanden ist.A gel that can be implanted in the human body is disclosed in I'SA. patent 3 357 434 known that carries an induction coil, the winding wire ends have a metallic surface and protrude from the implantable housing and are designed in the manner of needle contacts, which has a capacitor in connection forms an electrical resonant circuit with the induction coil, and in its area an to the induction coil connected rectifier is available.

Die bekannten Vorrichtungen sind zu Führung uiid Heilung frakiurierter Knochen weder bestimmt noch geeignet, da sie ganz anderen Zwecken dienen und Weder eine Stützung noch Heilung eines frakturierten Knochens bewirken können.The known devices are not intended to guide and heal fractured bones nor suitable, since they serve completely different purposes and are neither a support nor a healing of a fractured one Cause bone.

Es ist ferner bekannt, daß organische Faserstrukluren, wie sie beispielsweise in Holz und in der Substanz des Knochens vorliegen, ein piezoelektrisches Verhalten zeigen und daß Gleichstrom in begrenztem Maß das Wachstum von Holz und Knochen fördern kann. Eine Neubildung von Fasctstrukttircn wurde vor allem an der negativen Elektrode der Stromquei-It is also known that organic fiber structures, as they exist, for example, in wood and in the substance of bone, a piezoelectric Show behavior and that direct currents promote the growth of wood and bones to a limited extent can. A new formation of fiber structure was mainly found on the negative electrode of the current source.
