Description

Chirurgische Fäden Es wurde gefunden, daB= sich Polyacrylnitril und Mischpolymerisate mit überwiegendem Gehalt an Acrylnitril hervorragend zur Herstellung von chirurgischen Fäden eignen.Surgical threads It has been found that polyacrylonitrile and Copolymers with a predominant content of acrylonitrile are excellent for production suitable of surgical threads.

In der Patentschrift 698 o2o wird die Verwendung von Polyvinylalkohol für chirurgische Zwecke als bekannt vorausgesetzt und statt dessen die Verwendung wasserunlöslicher Polyvinylverbindungen, wie Ester, Äther oder Acetale des Polyvinylalkohols oder Ester der Polyacrylsäure, vorgeschlagen. Wie in der genannten Patentschrift bereits erwähnt ist (S. i, Zeilen 470 48)q läBt sich Polyvinylalkohol infolge seiner Wasserlöslichkeit nicht in den üblichen wäBrigen Sterilisierlösungen aufbewahren. Die anderen a. a. O. genamiten Polyvinylverbindungen sind zwar wasserunlöslich, haben aber den Nachteil der geringen Hitzebeständigkeit sowie der Quellbarkeit in Alkohol Diese beiden Eigenschaften wirken sich ungünstig für die Sterilisation, im einen Fall für die Trockensterilisation und im anderen Fall für die Sterilisation in Alkohol, aus.In the patent specification 698 o2o the use of polyvinyl alcohol for surgical purposes is assumed to be known and instead the use of water-insoluble polyvinyl compounds, such as esters, ethers or acetals of polyvinyl alcohol or esters of polyacrylic acid, is proposed. As already mentioned in the cited patent specification (p. 1, lines 470 48) q, polyvinyl alcohol cannot be stored in conventional aqueous sterilizing solutions because of its solubility in water. The other polyvinyl compounds mentioned above are insoluble in water, but have the disadvantage of poor heat resistance and swellability in alcohol. These two properties are unfavorable for sterilization, in one case for dry sterilization and in the other case for sterilization in alcohol .

Aus der Patentschrift 8.37 751 sind Polyamide als chirurgische Nähfäden bekannt. Die Polyamide stellen jedoch ein praktisch nicht resorbierbares chirurgisches Nahtmaterial dar. Dieser Nachteil schließt sie von der Verwendung als chirurgische Fäden für Innennähte aus.The patent specification 8.37 751 discloses polyamides as surgical sewing threads known. However, the polyamides represent a practically non-absorbable surgical method Sutures This disadvantage precludes them from being used as surgical sutures for Inside seams.

Im Gegensatz hierzu sind die aus Polymerisaten oder Mischpolymerisaten des Acrylnitrils bestehenden Fäden bei ihrer Verwendung als chirurgisches Nahtmaterial allen bisher beschriebenen Fäden überlegen.In contrast, those are made of polymers or copolymers of the acrylonitrile existing threads when used as surgical sutures superior to all threads described so far.

Die erfindungsgemäß zu verwendenden Fäden sind infolge ihrer hohen Temperaturbeständigkeit trocken bis zu.i2o° sterilisierbar. Sie unterscheiden sich hierin wesentlich von den bisher verwendeten natürlichen Därmen (Catgut). Infolge ihrer Beständigkeit gegen Wasser und die üblichen organischen Lösemittel, insbesondere Alkohol, sind die Fäden auch in gespanntem Dampf oder in Wasser sowie in Alkohol sterilisierbar. Beim Aufbewahren in z. B. 7o°/jgem Alkohol oder in Wasser zeigen sie keine Veränderung. Die Fäden der vorliegenden Erfindung unterscheiden sich dadurch vorteilhaft von den bisher empfohlenen Polyvinylverbindungen.The threads to be used according to the invention are due to their high Temperature resistance dry up to i2o ° sterilizable. They are different here essentially from the previously used natural intestines (catgut). As a result their resistance to water and the usual organic solvents, in particular Alcohol, the threads are also in tensioned steam or in water as well as in alcohol sterilizable. When stored in z. B. show 70 ° / jgem alcohol or in water they no change. The threads of the present invention differ in this advantageous from the polyvinyl compounds recommended so far.

Wie weiterhin Versuche, bei denen die Fäden subcutan oder in die Leibeshöhle von Ratten versenkt wurden, ergeben haben, erfolgt spätestens nach 21/2 Monaten eine vollständige Resorption. Die Fäden unterscheiden sich hierdurch vorteilhaft von den Polyamidfäden.As continue experiments in which the sutures are subcutaneous or into the body cavity were sunk by rats, takes place after 21/2 months at the latest complete absorption. In this way, the threads differ advantageously from the polyamide threads.

Das Material der hier verwendeten Fäden zeigt außerdem keine cancerogene Wirksamkeit.The material of the threads used here is also not carcinogenic Effectiveness.
