Abstract

Use of a separate needle with the thread is avoided. To this end, metal is to be applied to the plastic thread, so that the end of the thread may itself serve as needle. The tipped thread is pref. made by cutting it across obliquely, evaporating Ag onto the cut end and Cr-plating over the Ag. The tipped end of the thread may be curved.

Description

Nähfaden für chirurgische ZweckeSuture thread for surgical use

Die Erfindung betrifft Nähfadenabschnitte aus Kunststoff für chirurgische Zwecke, insbesondere für Mikrochirurgie, sowie ein Verfahren zur Herstellung solcher Abschnitte.The invention relates to suture thread sections made of plastic for surgical Purposes, in particular for microsurgery, and a method for producing such Sections.

Nähfadenabschnitte der genannten Art werden bisher in Verbindung mit einer Nadel gebracht. Aufgabe der Erfindung ist, die Nadel entbehrlich zu machen. Zu diesem Zweck ist erfindungsgemäß auf das Ende des Fadenabschnittes Metall aufgebracht und das Ende selbst als Nadel ausgebildet. Vorzugsweise wird das als Nadel ausgebildete Ende des Fadenabschnittes bogenförmig gestaltet.Sewing thread sections of the type mentioned are so far in connection with brought to a needle. The object of the invention is to make the needle dispensable. For this purpose, according to the invention, metal is applied to the end of the thread section and the end itself is designed as a needle. This is preferably designed as a needle End of the thread section designed arcuately.

Bei der Herstellung der Nähfabenabschnitte wird erfindungsgemäß so verfahren, daß zunächst das Ende des Nähfadenabschnittes schräg abgeschnitten, auf das Ende Silber aufgedampft und das Ende hartverohromt wird. Das hartverchromate Padenende ist dann von einer metallischen Hülle umgeben, die eine Nadel bildet.According to the invention, this is how the sewing thread sections are produced proceed that first the end of the sewing thread section is cut off at an angle the end is vapor-deposited silver and the end is hard-eared. The hard chrome The end of the pade is then surrounded by a metallic sheath that forms a needle.

Ein Ausführungsbeispiel der Erfindung ist im folgenden anhand der Zeichnung beschrieben, in dieser zeigen: Fig. 1 einen Nähfadenabschnitt gemäß der Erfindung zum Teil im Schnitt und in stark vergrößertem Maßstab und Fig. 2 den gleichen Nähfaden mit einem bogenförmig gestalteten Ende.An embodiment of the invention is described below with reference to FIG The drawings, in which: FIG. 1 shows a suture thread section according to FIG Invention partly in section and on a greatly enlarged scale and FIG. 2 shows the same Sewing thread with a curved end.

In der Zeichnung bezeichnet 1 einen Kuststoffaden, z0 B.In the drawing, 1 denotes a Kuststoffaden, e.g.

aus Nylon, dessen Ende schräg abgeschnitten ist. Auf das Ende des Fadens ist eine Silberschicht 2 aufgedampft und auf diese Schicht wiederum eine Schicht 3 aus Chrom aufgebracht, d. h.made of nylon, the end of which is cut off at an angle. At the end of the A silver layer 2 is vapor-deposited on the thread, and another layer is applied to this layer Layer 3 of chrome applied, d. H.

das mit der Silberschicht 2 versehene Ende wird nach dem Aufdampfen der Silberschicht 2 hartverchromt. Das äußere Ende des Nähfadenabschnittes ist so von einer metallischen Halle umgeben, die auch die schräge Stirnfläche des Fadens bedeckt.the end provided with the silver layer 2 becomes after the vapor deposition the silver layer 2 hard chrome plated. The outer end of the suture thread section is like this surrounded by a metallic hall, which is also the sloping face of the thread covered.

Die Hülle bildet die eigentliche Nadel.The sheath forms the actual needle.

Nach Fig. 2 bildet das schräg abgeschnittene Ende des Nähfadenabschnittes einen Bogen 5. Auf diesen Bogen, d. h. nach der bogenförmigen Verformung des Fadens, werden die Silberschicht 2 und die Chromschicht 3 aufgebracht. Anstelle des Bogens kann dem Fadenende die - chirurgisch gesehen - Jeweils günstigste Form gegeben werden.According to FIG. 2, the obliquely cut end of the suture thread section forms an arch 5. On this arch, i. H. after the arcuate deformation of the thread, the silver layer 2 and the chrome layer 3 are applied. Instead of the bow the thread end can be given the most favorable shape in each case from a surgical point of view.
