Description
Chirurgisches Verschlußmaterial Die Eigenschaften von chirurgischem Nahtmaterial, wie Zugfestigkeit, Resorbierbarkeit, Reizlosigkeit u. dgl., hängen u. a. in hohem Grade von der Qualität des Rohmaterials ab. So ist insbesondere von tierischem Rohmaterial bekannt, daß sich in den Geweben Stellen befinden, die infolge von Fettanlagerungen, von Anhäufung von Blutgefäßen und ähnlichem u. a. ein geringer festes strukturelles Gefüge aufweisen, das später am fertigen Faden eine geringere Zugfestigkeit zeigt. Um diesem Übelstande entgegenzutreten und dadurch u. a. die Zugfestigkeit an diesen Stellen zu erhöhen, werden nach der Erfindung bereits vor oder während der weiteren Verarbeitung die Gewebeteile oder die Darmteile zweckmäßig mit Polymerisaten von Monovinylverbindungen getränkt. Gleichzeitig läßt sich durch eine derartige Imprägnierung die Resorptionsdauer in bestimmter Richtung beeinflussen und im gegebenen Falle eine reaktionslose Einheilung des Fadenmaterials erzielen.Surgical Closure Material The properties of surgical Sutures, such as tensile strength, absorbability, lack of irritation and the like, hang i.a. depends to a large extent on the quality of the raw material. So in particular is of animal raw material known that there are places in the tissues that result of fat deposits, accumulation of blood vessels and the like, among others. a little have a solid structural structure, which later on the finished thread will be less Shows tensile strength. In order to counteract this disadvantage and thereby inter alia. the To increase tensile strength at these points, according to the invention are already before or the tissue parts or the intestinal parts expediently during further processing impregnated with polymers of monovinyl compounds. At the same time lets through such an impregnation influence the resorption time in a certain direction and, in the given case, achieve unresponsive healing of the thread material.
Das Verfahren ist anwendbar auf tierische Fasern, wie sie im üblichen Catgut Verwendung finden, auf Muskelfasern und andere Fasern tierischer Herkunft, auf Seide, Wolle, ferner auf pflanzliche Fasern, wie Baumwolle, schließlich auch auf geeignete zweckentsprechende Kombinationen. Das Verfahren gestattet insbesondere auch, aus an sich mehr oder weniger ungeeignetem Rohmaterial, z. B. ungenügend zugfestem, ungleichmäßigem, brauchbares Nahtmaterial zu gewinnen.The method is applicable to animal fibers, as in the usual Catgut is used on muscle fibers and other fibers of animal origin, on silk, wool, and also on vegetable fibers such as cotton, finally on suitable appropriate combinations. The procedure allows in particular also, from per se more or less unsuitable raw material, z. B. insufficient tensile strength, to gain uneven, usable suture material.
AlspolymereMonovinylverbindungenseien beispielsweise angeführt Polyvinylalkohole, Polyvinylester, Polyvinylacetale, Polyacrylsäureester und deren Derivate u. a. mehr.Examples of monovinyl compounds are polyvinyl alcohols, Polyvinyl esters, polyvinyl acetals, polyacrylic acid esters and their derivatives, among others. more.
Zur Ausführung des Verfahrens wird dem Rohmaterial die Polyvinylverbindung in einem zweckentsprechendenStadium desArbeitsganges einverleibt. Man kann z. B. die Gewebebänder vor oder während der Verarbeitung zu Fäden mit den polymeren Monovinylverbindungen tränken. plan kann das Faser- bzw. Rohfadenmaterial in einer Lösung, Suspension oder gegebenenfalls Schmelze der Polymonovinylverbindungen weiterverarbeiten, z. B. zwirnen, drehen o. dgl.The polyvinyl compound is added to the raw material to carry out the process incorporated at an appropriate stage of the work process. You can z. B. the fabric tapes before or during processing into threads with the polymeric monovinyl compounds soak. The fiber or raw thread material can be planar in a solution or suspension or, if appropriate, further process the melt of the polymonovinyl compounds, e.g. B. twist, turn or the like.
Besonders geeignet scheinen zur Ausführung des vorliegenden Verfahrens die polymeren Vinylalkohole oder ihre sich noch ähnlich verhaltenden partiellen Derivate. Durch Wahl der niedrig- oder hochpolymeren Qualitäten hat man es in der Hand, das gewünschte Fasermaterial mit einer leicht oder schwer löslichen bzw. leicht oder schwer resorbierbaren Imprägnierung zu versehen. Bei Verwendung der polymeren Monovinylverbindungen, insbesondere von Polyvinylalkohol, ist man in der Lage, durch Zusatz von geeigneten, die Resorbierbarkeit erhöhenden Stoffen, insbesondere von Elektrolyten, vorzugsweise organischen Säuren, z. B. Milchsäure, Essigsäure, den Resorptionsvorgang zu begünstigen oder durch anders geartete Zusätze zu verlangsamen. Der Zusatz vonresorptionsbefördemdenElektrolyten zu Polyvinylverbindungen allein ist an sich bekannt, nicht jedoch in Verbindung mit der Einverleibung von Polyvinylverbindungen in natürliches Fadenmaterial.Appear particularly suitable for carrying out the present method the polymeric vinyl alcohols or their partial ones, which still behave similarly Derivatives. By choosing the low or high polymer qualities you have it in the Hand, the desired fiber material with an easily or difficultly soluble or easily or hard-to-absorb impregnation. When using the polymer Monovinyl compounds, especially of polyvinyl alcohol, are able to through Addition of suitable, absorbability-increasing substances, in particular of Electrolytes, preferably organic acids, e.g. B. lactic acid, acetic acid, the To favor the resorption process or to slow it down by other types of additives. The addition of absorption promotes the electrolyte to polyvinyl compounds alone is known per se, but not in connection with the incorporation of polyvinyl compounds in natural thread material.
Auch in anderer Richtung wirksame an sich bekannteZusätze, z. B. therapeutisch wirksame, bakterizide, ebenso wie andere erwünschte Maßnahmen, z. B. besondere Keimfreiheit gewährleistendes Arbeiten, können mit dem vorliegenden Verfahren kombiniert werden. Auch diese Maßnahmen sind in Verbindung mit der Einverleibung von Polyvinylverbindungen in natürliches Fadenmaterial neu.Also effective in a different direction are additives known per se, e.g. B. therapeutic effective, bactericidal, as well as other desirable measures, e.g. B. special sterility guaranteeing work can be combined with the present method. These measures are also related to the incorporation of polyvinyl compounds in natural thread material new.
