Abstract
Description
Die Erfindung betrifft eine chirurgische Zange der im Oberbegriff des Anspruches 1 genannten Art.The The invention relates to a surgical forceps in the preamble of Claim 1 mentioned type.
Gattungsgemäße Zangen sind mit ihrem langgestreckten Schaft zum endoskopischen Einsatz vorgesehen. Durch die lösbare Verbindung der Hülse mit dem Schaft ist die Zange an dieser Stelle zwischen Schaft und Handgriff auseinandernehmbar. Diese Auseinandernehmbarkeit dient in erster Linie dazu, die Reinigungs- und Sterilisiermöglichkeiten zu verbessern, so dass die Zange auch bei hochsterilem chirurgischen Einsatz wiederverwendet werden kann.Generic pliers are intended with their elongated shaft for endoscopic use. By the detachable Connection of the sleeve with The shaft is the pliers at this point between the shaft and handle detachable. This disassembly serves first Line to improve the cleaning and sterilization options, so that the forceps are reused even in highly sterile surgical use can be.
Gattungsgemäße Zangen sind ferner mit einer Feder versehen, die beim Schließen der Zange mit hoher Schließkraft federnd nachgibt. Das kann zu verschiedenen Zwecken verwendet werden, z. B. zur Überlastbegrenzung, um Zerstörungen der Zange zu verhindern oder auch um in Verbindung mit einer Verriegelung der Zange längeres Halten unter konstanter Kraft zu ermöglichen.Generic pliers are further provided with a spring which when closing the Pliers with high clamping force yielding resiliently. This can be used for various purposes z. For overload limitation, for destruction of the To prevent pliers or even in conjunction with a lock the pliers longer Hold under constant force to allow.

gattungsgemäße Zange
ist aus
Die Aufgabe der vorliegenden Erfindung besteht darin, eine gattungsgemäße Zange mit verbesserter Reinigbarkeit zu schaffen.The Object of the present invention is a generic pliers with improved cleanability.
Diese Aufgabe wird mit den Merkmalen des Kennzeichnungsteiles des Anspruches 1 gelöst. Weitesbildungen folgen in den abhängigen Patentansprüchen.These Task is with the features of the characterizing part of the claim 1 solved. Weitesbildungen follow in the dependent claims.
Erfindungsgemäß ist die Hülse mit ihrem die Schraubenfeder tragenden Bereich derart angeordnet, dass sie den Schaftteil des Handgriffes überragt. Nach Trennung des Handgriffes vom Schaft ist die Schraubenfeder folglich nach außen völlig offen. Dieses geometrisch sehr komplizierte Teil kann somit äußerst wirkungsvoll und gründlich gereinigt und sterilisiert werden.According to the invention Sleeve with their helical spring bearing area arranged such that it projects beyond the shaft part of the handle. After separation of the Handle from the shaft, the coil spring is therefore completely open to the outside. This geometrically very complicated part can thus be extremely effective and thoroughly be cleaned and sterilized.
Vorteilhaft ist gemäß Anspruch 2 eine die Schraubenfeder lösbar umgebende Abdeckung vorgesehen, die während des Gebrauchs die Feder nach außen abdeckt, also z. B. die Einklemmgefahr in der Schraubenfeder beseitigt, nach Abnehmen aber die Schraubenfeder zu Reinigungszwecken freigibt.Advantageous is according to claim 2 a solvable the coil spring surrounding cover provided, which during use the spring after Outside covers, so z. B. eliminates the risk of entrapment in the coil spring, after removing but the coil spring releases for cleaning purposes.
Diese Abdeckung ist vorteilhaft gemäß Anspruch 3 am Schaft angeordnet, so dass sie bei Trennung von Handgriff und Schaft automatisch abgenommen wird und die Schraubenfeder zur Reinigung freigibt.These Cover is advantageous according to claim 3 arranged on the shaft so that they are separated by the handle and Shaft is automatically removed and releases the coil spring for cleaning.
Vorteilhaft gemäß Anspruch 4 ist an der Hülse eine Verdrehmöglichkeit zwischen Handgriff und Schaft vorgesehen, womit das Zangenmaul gegenüber dem Handgriff verdrehbar ist.Advantageous according to claim 4 is on the sleeve a twisting possibility provided between the handle and shank, whereby the forceps jaw opposite the Handle is rotatable.
Ohne Verriegelung wäre eine Zange mit Feder z. B. nur gegen Überlast gesichert. Ist vorteilhaft gemäß Anspruch 5 eine Verriegelung vorgesehen, so lässt sich die Zange in gespanntem Zustand verriegeln, was z. B. beim Einsatz als Nadelhalter von Vorteil ist oder wenn in weiterhin vorteilhafter Ausgestaltung gemäß Anspruch 6 zwischen den Branchen eine Wärmeerzeugung möglich ist, mit der z. B. ein Gefäß unter konstanter Klemmkraft koaguliert werden kann.Without Locking would be a pair of pliers with spring z. B. secured only against overload. Is advantageous according to claim 5 provided a lock, so the pliers can be in tensioned Lock state, what z. B. when used as a needle holder advantage is or if in a further advantageous embodiment according to claim 6 heat generation between industries possible is, with the z. B. a vessel below constant clamping force can be coagulated.
In der Zeichnung ist die Erfindung beispielsweise in einer einzigen Figur dargestellt, die einen Achsschnitt durch eine erfindungsgemäße chirurgische Zange zeigt.In the drawing is the invention, for example, in a single Figur shown, which is an axial section through a surgical inventive Pliers shows.
