Zur Herstellung einer festen Knochenverbindung kann das Kohlefasermaterial mit Glasionomer- Material(ien) getränkt und in Knochendefekte eingeführt werden.This is the glass ionomer material (s) of the Osteosyn Harden thesemateriales to [a] glass ionomer cement (s) calmly. For establishing a solid bone connection can the carbon fiber material with glass ionomer Material (ien) soaked and introduced into bone defects will.
Vorteilhaft werden bei der erfindungsgemäßen Verwendung die Kohlefasern in einem Kohlefaserbündel eingesetzt, wobei sie wahlweise als Ganzes genutzt oder als Geflecht verlegt werden. Be advantageous in the use according to the invention the carbon fibers used in a carbon fiber bundle, using them either as a whole or as a network be relocated.
Die Erfindung kann in den folgenden Bereichen besonders vorteilhaft angewandt werden:The invention can be particular in the following areas can be used advantageously:
- a) Zur Behebung von Knochendefekten nach Unfällen, Ent zündungen, Tumoren bzw. nach Operationen, die nach Unfällen, Entzündungen, Tumoren durchgeführt werden müssen. Insbesondere können mit dem erfindungsgemäßen Osteosynthesematerial auch Distanzen überbrückt werden, die aufgrund von Unfällen oder sonst in Knochen entstehen, beispielsweise nach operativer Beseitigung von Splitterstücken aus Knochen, insbesondere Schädel basisknochen.a) To correct bone defects after accidents, Ent ignitions, tumors or after operations after Accidents, inflammation, tumors are carried out have to. In particular, with the invention Osteosynthesis material also bridging distances those due to accidents or otherwise in bones arise, for example after surgical removal of fragments of bone, especially skulls base bone.
- b) Zur Schaffung dauerhafter Verbindungen bei Knochen brüchen. Auch hier ist besonders vorteilhaft, daß Distanzen überbrückt werden können.b) To create permanent connections in bones breaks. It is also particularly advantageous here that Distances can be bridged.
- c) Zur Schaffung und Fixierung von Mittelohrprothesen. Hierbei können ebenfalls Distanzen durch Kohlefasern überbrückt werden.c) To create and fix middle ear prostheses. Distances can also be caused by carbon fibers be bridged.
Die Kohlefasern des erfindungsgemäßen Osteosynthese materiales bzw. die mit ihm herstellbaren Prothesen schaffen ein besonders flexibles und formbares sowie den jeweiligen Gegebenheiten besonders gut anpaßbares System für den Anwender. Das Kohlefasermaterial kann nach dem jeweiligen Verwendungszweck gewählt werden. Je nach Anwendungsfall ist die Verwendung von Kohlefaserbündeln oder von Kohlefasergeflechten oder Einzelfasern vorteil haft. Das Kohlefasermaterial kann vor der Anwendung zuge schnitten und auch entsprechend dem Anwendungszweck in weiten Grenzen frei verformt worden sein.The carbon fibers of the osteosynthesis according to the invention create material or the prostheses that can be produced with it a particularly flexible and malleable as well as the System that is particularly adaptable to the circumstances for the user. The carbon fiber material can after can be selected for the respective purpose. Depending on Use case is the use of carbon fiber bundles or of carbon fiber braids or single fibers arrested. The carbon fiber material can be fed before use cut and also in accordance with the application wide limits have been freely deformed.
Die Anwendung des Kohlefasermaterials hat den weiteren Vorteil, daß es hygroskopische Eigenschaften hat und damit auch in den Fällen die Abbindung des feuchtigkeitsempfind lichen Glasionomerzements ermöglicht, in denen viel Flüssig keit anfällt. Ein derartiges "Zuviel" von Flüssigkeit im Operationsfeld tritt beispielsweise bei der Versorgung von Knochendefekten im Bereich der Schädelbasis und gleichzeitig bestehendem Liquorfluß auf. Bei Röhrenknochen tritt Blut aus den eröffneten Markräumen aus. In diesen Fällen kann die überschüssige Flüssigkeit durch die Kohle fasern aufgesaugt und aufgenommen werden. Damit können Voraussetzungen geschaffen werden, die zur optimalen Aus härtung des Glasionomerzements notwendig sind. Hierfür wird zwar etwas, aber nicht zu viel Feuchtigkeit benötigt.The application of the carbon fiber material has another Advantage that it has hygroscopic properties and therefore also in the cases the setting of the moisture sensitivity Lichen glass ionomer cement, in which a lot of liquid is incurred. Such "too much" liquid in the surgical field, for example, occurs during care of bone defects in the area of the skull base and at the same time existing CSF flow. For long bones blood comes out of the opened medulla. In these The excess liquid can fall through the coal fibers are absorbed and absorbed. So that can Prerequisites are created for the optimal out hardening of the glass ionomer cement are necessary. Therefor something is needed, but not too much moisture.

Kalfateisen ist besonders vorteilhaft zur Schaffung dauerhafter Ver bindungen in feuchten Bereichen, z. B. in der Schädel basischirurgie und bei eröffneten Markräumen. Sogenannte "Kalfateisen" sind in vergrößerter Form bereits aus dem Schiffsbau bekannt. Die Kohlefasern funktionieren in diesem Sinne als "Kalfatwolle". Der Vorteil der "Kalfattechnik" besteht darin, daß das Zuviel von Flüssigkeiten unterbunden wird.The invention also relates to a device for Implementation of the use according to the invention, which is characterized by being an auxiliary instrument, in particular a potassium iron, a button probe and / or is a holding forceps and / or a ball needle. Kalfa iron is particularly beneficial for creating permanent ver bindings in damp areas, e.g. B. in the skull basic surgery and in open medullary spaces. So-called "Kalfateisen" are already from the Known shipbuilding. The carbon fibers work in this Senses as "calf wool". The advantage of "calf technology" is that the excess of liquids is prevented.
Zur Schaffung dauerhafter Verbindungen (vgl. oben b) in Arealen mit Scherkräften ist es vorteilhaft, Halteein richtungen, beispielsweise Halte- bzw. Repositionszangen in verschiedenen Größen, die beispielsweise von der Herstellerfirma Synthes vertrieben werden, zu verwenden. Auch der Einsatz von Tuchklammern ist möglich.To create permanent connections (see above b) in Areas with shear forces are beneficial to hold directions, for example holding or reduction pliers in different sizes, for example from the Manufacturer company Synthes are sold to use. The use of cloth clips is also possible.
