Description
Nadel für Injektionsspritzen. Es gibt Nadeln für Injektionsspritzen mit einem auf der Nadel angebrachten Anschlag. Nach der Erfindung ist der Anschlag fest und unverschiebbar auf der Nadel in einem solchen Abstande zwischen dem Nadelhalter und der Nadelspitze angeordnet, daß dabei der Doppelzweck erreicht wird, die Einstichtiefe der Nadel in das Gewebe zu begrenzen und das Herausziehen der Nadelspitze aus dem Gewebe zu ermöglichen, wenn die Nadel am Einspannende abbricht.Syringe needle. There are needles for hypodermic syringes with a stop attached to the needle. According to the invention is the stop fixed and immovable on the needle at such a distance between the needle holder and the needle tip arranged so that the dual purpose is achieved, the puncture depth limiting the needle into the tissue and withdrawing the needle tip from the Allow tissue if the needle breaks at the clamping end.
In der Zeichnung ist eine Ausführungsform der Erfindung dargestellt, und zwar zeigt Abb. i eine Seitenansicht- des Erfindungsgegenstandes in der Arbeitsstellung, während Abb. 2 ein achsialer Längsschnitt und Abb: 3 eine Draufsicht der Nadel mit dem Halter ist.In the drawing, an embodiment of the invention is shown, namely Fig. i shows a side view of the subject of the invention in the working position, while Fig. 2 is an axial longitudinal section and Fig: 3 is a plan view of the needle the holder is.
Das dicke Ende ix der röhrenförmigen Nadel io ist in bekannter Weise in der achsialen Bohrung i2 des nach vorn verjüngten Endes des Nadelhalters 14 befestigt, welcher mit dem üblichen Innengewinde 15 zum Aufschrauben auf das Mundstück 16 der Injektionsspritze versehen ist. Um nun einmal die Einstechiiefe der Nadel io in das Gewebe 17 zu begrenzen und das andere Mal beim Abbrechen der Nadel an dem Einspannende leichtes und bequemes Herausziehen der abgebrochenen Nadel aus dem Gewebe zu ermöglichen, ist gemäß der Erfindung in geeignetem Abstande vom Nadelhalter zwischen diesem und der Nadelspitze ein Anschlag 18 fest und unverschiebbar auf der Nadel angeordnet. Zweckmäßig ist der Anschlag 18 scheibenförmig mit abgerundeten Kanten ausgebildet. Er begrenzt beim Einstechen der Nadel in das Gewebe die Einstechtiefe, und falls die Nadel abbricht, was meist am Einspannende erfolgt, ermöglicht er es, den abgebrochenen Teil sicher aus dem Gewebe herauszuziehen, so daß ein nachträglicher operativer Eingriff zur Entfernung der Nadelspitze unnötig wird. Um Verletzungen des Knochens oder der Knochenhaut beim Einstich der Nadel auszuschließen, , ist auf dem Halter 14 eine Strichmarke 22 vorgesehen, welche es ermöglicht, die jeweilige Lage der Schrägfläche 21 an der Nadelspitze 2o auch bei eingestochener Nadel feststellen zu können, indem die Nadel so im Halter befestigt wird, daß die Schrägfläche 21 an der Spitze sich unten befindet, wenn die Strichmarke z2 oben ist, wie Abb. 3 es erkennen läßt.The thick end ix of the tubular needle io is fastened in a known manner in the axial bore i2 of the forwardly tapered end of the needle holder 14, which is provided with the usual internal thread 15 for screwing onto the mouthpiece 16 of the injection syringe. In order to limit the penetration depth of the needle into the tissue 17 and to allow the broken needle to be pulled out of the tissue easily and conveniently when the needle breaks off at the clamping end, according to the invention there is a suitable distance from the needle holder between this and the needle tip a stop 18 is fixedly and immovably arranged on the needle. The stop 18 is expediently designed in the form of a disk with rounded edges. It limits the penetration depth when the needle is inserted into the tissue, and if the needle breaks, which usually takes place at the clamping end, it enables the broken part to be safely pulled out of the tissue, so that subsequent surgery to remove the needle tip is unnecessary. In order to rule out injuries to the bone or periosteum when the needle is inserted, a line mark 22 is provided on the holder 14, which makes it possible to determine the respective position of the inclined surface 21 on the needle tip 2o even when the needle is inserted, by placing the needle in this way is fastened in the holder that the inclined surface 21 is at the top at the bottom when the line mark z2 is at the top, as Fig. 3 shows.
