Title
(DE) CHIRURGISCHE NÄHNADEL
(EN) SURGICAL SUTURING NEEDLE
(FR) AIGUILLE A COUDRE CHIRURGICALE
Abstract
(DE)
Die Erfindung betrifft eine chirurgische Nähnadel (1), die nach dem Weberschiffchenprinzip zwischen den beiden Maulteilen eines Nähgeräts umgesetzt werden kann. Die Nähnadel weist eine Krümmung derart auf, daß sich die gerade nicht eingespannte Spitze (2) und die Achse (4) der Nadel (1) auf der Bewegungsbahn der anderen, eingespannten Nadelspitze (2) bewegt. Damit die Nähnadel (1) definiert ausgerichtet in den Maulteilen eingespannt werden kann, weist sie an ihren beiden Spitzenbereichen eine flächige, schuhsohlenartige Ausnehmung (3) auf, über die sie kraftschlüssig in der jeweiligen Nadelhalterung eingespannt wird. Zum weitestgehend atraumatischen Durchstechen von Gewebe hat sich ein Kegelwinkel (8) an den beiden Nadelspitzen (2) von 25 bis 35° als optimal erwiesen.
(EN)
The invention relates to a surgical suturing needle (1) which can be moved on the shuttle principle between the two jaws of a suturing device. The suturing needles are curved in such a way that the straight unclamped point (2) and the axis (4) of the needle (1) moves on the path of the other clamped needle point. In order for the suturing needle (1) can be clamped directionally in the jaws it has a flat, shoe-sole-like recess (3) in its two point regions via which it is frictionally clamped in the needle holder. A wedge angle (8) at both needle points (2) of 25 to 35° has been found best in order to suture tissues with the least traumatic effect.
(FR)
L'invention concerne une aiguille à coudre chirurgicale (1) pouvant être déplacée entre les deux mâchoires d'une machine à coudre. L'aiguille à coudre (1) présente une courbe de telle façon que la pointe droite non bloquée et l'axe de l'aiguille se meuvent sur la trajectoire de l'autre pointe qui est bloquée. Pour que l'aiguille à coudre (1) puisse être bloquée dans les mâchoires dans une direction définie, chacune de ses extrémités présente un évidement (3) plat ressemblant à une semelle, par lequel elle peut être bloquée par liaison de force dans le porte-aiguille correspondant. Pour un piquage des tissus le plus possible atraumatique, un angle de cône (8) aux deux pointes (2) de l'aiguille de 25 à 35° s'est avéré une solution optimale.
