Es ist eine Gefäßklemme der genannten Art vorgeschlagen wor¬ den (P 28 52 559.9), deren Schaft (Außenelement und Innen¬ element) federnd flexibel ausgebildet ist. Nachteilig ist dabei, daß durch die nachgiebige Ausbildung die Handhabung der Klemme erschwert ist und daß zum Anlegen beide Hände gebraucht werden müssen. Im übrigen kann zwar der federnde Schaft aus dem Operationsfeld weggebogen werden, jedoch muß er ständig gehalten werden, da er sonst wieder zurückfedert.A vascular clamp of the type mentioned has been proposed (P 28 52 559.9), the shaft (outer element and inner element) of which is designed to be resiliently flexible. The disadvantage here is that the flexible training makes the handling of the clamp difficult and that both hands must be used to put on. Otherwise, the resilient shaft can be bent away from the operating field, but it must be held constantly, otherwise it will spring back again.
Der Erfindung liegt die Aufgabe zugrunde, eine Gefäßklemme der eingangs genannten Art zu schaffen, die einfach mit einer Hand anlegbar ist. Dies wird erfindungsgemäß dadurch erleichtert, daß das Außenelement des Klemmenschaftes als flexible, vorzugsweise federnde Hülse ausgebildet ist und daß das Innenelement ein plastisch biegbarer Stab ist. Hier¬ durch.,ist es möglich, den Schaft in eine beliebige Form zu biegen, die dann auch beibehal.ten wird, ohne daß die Funktion der Klemme behindert wird.The invention has for its object to provide a vascular clamp of the type mentioned that is easy to put on with one hand. This is made easier according to the invention in that the outer element of the clamping shaft is designed as a flexible, preferably resilient sleeve and in that the inner element is a plastically bendable rod. In this way, it is possible to bend the shaft into any shape which will then be retained without the function the clamp is hindered.
Vorzugsweise besteht das Außenelement aus einem schrauben¬ förmig gewundenen Federdraht, während das Innenelement aus einem plastisch biegbaren Draht oder auch aus einem Rohr aus plastisch formbarem Material, dessen Innenraum durch einen Innendraht oder dergleichen ausgefüllt ist, besteht.The outer element preferably consists of a helically wound spring wire, while the inner element consists of a plastically bendable wire or also of a tube made of plastically formable material, the interior of which is filled with an inner wire or the like.
Das Rohr kann aus Messing, Kupfer oder Neusilber oder ähn¬ lichen Materialien bestehen, während der Innendraht zweck¬ mäßig ein Federdrahtseil sein kann.The tube can consist of brass, copper or nickel silver or similar materials, while the inner wire can expediently be a spring wire rope.
Durch die besondere Ausbildung des Schaftes wird auchim ge¬ bogenen Zustand eine sichere Funktion gewährleistet, während ein Abknicken des inneren Stabes oder Drahtes verhindert wird, so daß auch nach längerem Gebrauch die einwandfreie Funktion gewährleistet ist.The special design of the shaft ensures reliable function even in the bent state, while kinking of the inner rod or wire is prevented, so that proper function is ensured even after prolonged use.
Die Erfindung ist im folgenden anhand der Zeichnung an Aus¬ führungsbeispielen näher erläutert. In der Zeichnung zeigen:The invention is explained in more detail below with the aid of exemplary embodiments. The drawing shows:
