Abstract
(DE)
Die Erfindung betrifft eine stanzarme Kanüle wie in Fig. 3 dargestellt, deren Kanülenrohr (2) im Bereich der Einstichspitze (4) in Richtung auf die Mittelachse (6) gebogen ist. Der Schliff besteht aus einem Grundschliff (8) und zwei Facettenschliffen (9), wobei die gesamte Schnittlinie zwischen Grundschliff und innerer Oberfläche der Kanüle abstumpfend verrundet ist.
(EN)
The invention concerns a cannula, as illustrated in the figure 3, whose wall (2) is bent, at the tip (4), in towards the longitudinal axis (6) of the needle. The needle tip is ground to give a basic ground zone (8) and two facets, the whole interface between the basic zone and the inside surface of the bore being rounded so that they are blunt.
(FR)
L'invention concerne une canule à faible effet de poinçonnage telle que celle représentée figure 3, dont le tube (2) est incurvé en direction de l'axe médian (6) au niveau de la pointe (4). La surface polie se compose d'une surface polie de base (8) et de deux surfaces polies biseautées (9) et l'ensemble de la ligne de coupe est arrondi et émoussé entre la surface polie de base et la surface intérieure de la canule.
