Abstract
Description
Die Erfindung betrifft eine endoskopische Zange der im Oberbegriff des Anspruchs 1 genannten Art.The The invention relates to an endoscopic forceps in the preamble of Claim 1 mentioned type.
Gattungsgemäße
Zangen sind aus der
Da der Abstandshalter die Kontaktfläche, auf der er befestigt ist, überragt, ist er empfindlich gegen Beschädigungen, die zum Abreißen des Abstandshalters führen können. Außerdem ergibt sich eine komplizierte Herstellung, da der isolie rende Abstandshalter sehr sorgfältig auf der elektrisch leitfähigen, also metallischen Kontaktfläche befestigt werden muss.There the spacer the contact surface on which he attached is, surmounted, it is sensitive to damage, which can lead to the tearing off of the spacer. In addition, a complicated production, since the insulating spacers very carefully on the electrically conductive, so metallic contact surface must be attached.
Die Aufgabe der vorliegenden Erfindung besteht darin, eine gattungsgemäße Zange konstruktiv einfacher und haltbarer zu machen.The Object of the present invention is a generic To make pliers structurally simpler and more durable.
Diese Aufgabe wird mit dem Merkmal des Kennzeichnungsteils des Anspruches 1 gelöst.These Task is with the feature of the characterizing part of the claim 1 solved.
Erfindungsgemäß ist der Abstandshalter elektrisch leitend und elektrisch leitend befestigt. Er kann insbesondere auch einstückig mit der Kontaktfläche ausgebildet sein oder zum Beispiel als metallischer Stift auf dieser durch Verschrauben, Verschweißen oder dergleichen befestigt sein. Alle diese Möglichkeiten führen zu einer nahezu unzerstörbaren Ausbildung des Abstandshalters und zu einer sehr einfachen Herstellung. Der Isolierbelag auf der gegenüberliegenden Kontaktfläche ist ebenfalls sehr einfach herstellbar. Er kann beliebig großflächig ausgebildet sein und sehr flach der Kontaktfläche anliegen, so dass er nicht beschädigungsgefährdet ist und sehr gut hält.According to the invention the spacer electrically conductive and electrically conductive attached. In particular, it can also be integral with the contact surface be formed or for example as a metallic pin on this fastened by screwing, welding or the like be. All these possibilities lead to one almost indestructible training of the spacer and to a very simple production. The insulating covering on the opposite Contact surface is also very easy to produce. He can be designed arbitrarily large area and lie very flat on the contact surface, so he does not is at risk of damage and keeps very well.
Vorteilhaft ist der Isolierbelag gemäß Anspruch 2 in einer Vertiefung eingelassen. Er kann mit seiner Oberfläche bündig mit der Oberfläche der Kontaktfläche liegen, so dass er kaum durch Berührungen abgerissen werden kann.Advantageous is the Isolierbelag according to claim 2 in one Well recessed. He can flush with its surface lie with the surface of the contact surface, so that he can barely be torn off by touch.
