Description

Atraumatische Nadel Bei chirurgischen Nadeln, die in das Gewebe des Patienten eindringen sollen, ist es erforderlich, daß rauhe Oberflächen, Vorsprünge und Absätze vermieden werden, weil dadurch Verletzungen, insbesondere von Blutgefäßen, entstehen können. Es sind daher statt Nadeln mit Öhr oder Schlitzen zum Befestigen des Nähfadens bereits Nadeln beschrieben worden, bei denen der Faden am Ende der Nadel, z. B. in einer Längsbohrung, befestigt ist.Atraumatic needle With surgical needles that are inserted into the tissue of the To penetrate the patient, it is necessary that rough surfaces, protrusions and heels are avoided because they cause injuries, especially of blood vessels, can arise. There are therefore instead of needles with eyes or slots for fastening of the sewing thread have already been described needles in which the thread at the end of the Needle, e.g. B. is fixed in a longitudinal bore.

Bei solchen an sich glatten Nadeln ist aber immer noch ein absatzartiger Übergang vom dickeren Nadelschaft zum dünneren Faden vorhanden, selbst wenn das Nadelende am Übergang zum Faden abgerundet ist. In the case of such needles, which are smooth in themselves, there is still a shoulder-like one There is a transition from the thicker needle shaft to the thinner thread, even if that The end of the needle is rounded at the transition to the thread.

Es hat sich herausgestellt, daß dieser Absatz noch zu Verletzungen führen kann. Bei einer atraumatischen Nadel, an deren ungeschlitztem Ende der Faden befestigt ist, wird der erwähnte Nachteil erfindungsgemäß dadurch vermieden, daß der Durchmesser der Nadel sich ohne Absatz allmählich auf den Durchmesser des Fadens verjüngt. It has been found that this paragraph still leads to injury can lead. In the case of an atraumatic needle, the thread at its unslit end is attached, the disadvantage mentioned is avoided according to the invention in that the diameter of the needle without a step gradually changes to the diameter of the thread rejuvenates.

In der Abbildung ist eine erfindungsgemäße Nadel dargestellt. Mit a ist die Nadel, mit c der Faden bezeichnet. Der erfindungsgemäße allmähliche Übergang von der Nadel zum Faden ist mit b bezeichnet. A needle according to the invention is shown in the figure. With a is the needle, c is the thread. The gradual transition according to the invention from needle to thread is denoted by b.
