Description
Für die chirurgische Nähtechnik finden gerade oder gebogene Näh- bzw. Heftnadeln Verwendung, die einen drehrunden, ovalen oder kantigen Querschnitt haben. Von diesen werden die drehrunden und die dreikantigen gebogenen Nadeln am häufigsten gebraucht. For surgical sewing technology, straight or curved sewing or stapling needles that have a rotating, oval or angular cross-section to have. Of these, the rotating needles and the triangular bent needles are on frequently used.
Die drehende Form ist für solche Nähte bestimmt, bei denen das Gewebe geringen Widerstand bietet und möglichst ohne Blutung hervorzurufen durchstochen werden soll. The rotating shape is intended for those seams where the fabric offers little resistance and punctured without causing bleeding if possible shall be.
Die dreikantige Nadel larird für die Naht solcher Gewebe verwendet, die dem Durchstechen einen besonderen Widerstand entgegensetzten; das ist vor allem die äußere Haut. Es ist jedoch allgemein bekannt, daß auch diese Nadelform sowohl am Menschen als auch besonders an den Haustieren einen erheblichen und unangenehmen Kraftaufwand erfordert, was sogar häufig dazu führt, daß die Nadel sich verbiegt und abbricht. Die Form der dreikantigen gebogenen Nadel ist aus derAbbildung in Ansicht und Querschnitt ersichtlich. Sie ist so ausgeführt, daß ihre drei Kanten in gleichmäßigem Verlauf in die Spitze übergehen. Es kommt daher beim Durchstechen von Gewebe an der Spitze keine Schneidwirkung zustande. Die Nadel wirkt vielmehr als Keil, der das Gewebe seitlich verdrängt. The triangular needle larird is used for the suturing of such tissues, who offered particular resistance to piercing; that is above all the outer skin. However, it is generally known that this needle shape as well in humans as well as especially in domestic animals a considerable and unpleasant one Requires force, which in fact often leads to the needle bending and breaks off. The shape of the triangular bent needle is from the figure in View and cross-section visible. It is designed so that its three edges merge evenly into the tip. It therefore occurs when piercing there is no cutting effect of tissue at the tip. Rather, the needle works as a wedge that displaces the tissue laterally.
Es ist daher leicht einzusehen, daß beim Nähen von zäher Haut mehr oder weniger erhebliche Kräfte benötigt werden, eine Tatsache, die von zahlreichen Chirurgen als übel und lästig empfunden wird.It is therefore easy to see that when sewing tough skin, more or less substantial forces are required, a fact by numerous Surgeons find it nasty and annoying.
In der Abbildung ist die Kontur der bisherigen und ebenso die Ausführung der neuen Nadel dar gestellt. Im Gegensatz zur bisherigen Ausführung wurde nämlich, wie ersichtlich, die Spitze in der Weise abgeschliffen, daß auf der konkaven Seite der Nadel eine Schneide entsteht, welche mit dem weiteren Verlauf der konkaven Kante einen stumpfen Winkel bildet und beim Durchstechen von zähem Gewebe wie eine Messerschneide wirkt. In the figure is the contour of the previous one and also the execution the new needle is presented. In contrast to the previous version, as can be seen, the point ground off in such a way that on the concave side the needle creates a cutting edge, which with the further course of the concave edge forms an obtuse angle and acts like a knife edge when piercing tough tissue works.
