Title
(EN) NEEDLE STRUCTURE COMPRISING A HOLLOW CANNULA AND A STYLET
(FR) STRUCTURE D'AIGUILLE COMPRENANT UNE CANULE CREUSE ET UN STYLET
Abstract
(EN)
Needle structure (1) comprising a hollow cannula (2) and a stylet (3) with a body (4) and a solid front end (5), which stylet (3) is mountable in, and retractable from the hollow cannula (2), wherein the body (4) of the stylet (3) comprises stylet members (6, 7) that are adjacent to each oth- er and are movable with respect to each other and that connect to each other at the solid front end (5) of the stylet (3) protruding from the cannula (2), wherein the stylet members (6, 7) are fixed at or near a proximal end (11) of the stylet (3) which is distant from the solid front end (5) and are mu- tually separated from each other by a slit (13) or slits ex- tending uninterruptedly from the proximal end (11) to the sol- id front end (5) of the stylet (3).
(FR)
La présente invention concerne une structure d'aiguille (1) comprenant une canule creuse (2) et un stylet (3) avec un corps (4) et une extrémité avant solide (5), lequel stylet (3) peut être monté dans la canule creuse et en être rétracté (2), le corps (4) du stylet (3) comprenant des éléments de stylet (6, 7) qui sont adjacents l'un à l'autre et qui sont mobiles l'un par rapport à l'autre et qui se connectent l'un à l'autre au niveau de l'extrémité avant solide (5) du stylet (3) faisant saillie à partir de la canule (2), les éléments de stylet (6, 7) étant fixés au niveau ou à proximité d'une extrémité proximale (11) du stylet (3) qui est distante de l'extrémité avant solide (5) et étant séparés les uns des autres par une fente (13) ou des fentes s'étendant de manière ininterrompue de l'extrémité proximale (11) à l'extrémité avant solide (5) du stylet (3).
