An injection device (26) for use with tissue of a mammalian body comprising a first tubular member (62) and a second tubular member (61) slidably disposed in the first tubular member. The first and second tubular members have respective proximal and distal extremities (62a, 62b; 61a, 61b). The distal extremity of the second tubular member is provided with a needle (64) that is extendable from the distal extremity of the first tubular member. The proximal extremity of the second tubular member is lockable relative to the proximal extremity of the first tubular member. The second tubular member has a column strength when locked within the first tubular member for limiting retraction of the second tubular member relative to the first tubular member during puncture of the tissue by the needle.
La présente invention a trait à un dispositif d'injection (26) destiné à être utilisé avec le tissu d'un corps mammalien comportant un premier organe tubulaire (62) et un deuxième membre tubulaire (61) monté à coulissement dans le premier organe. Les premier et deuxième organes tubulaires présentent respectivement des extrémités proximales et distales (62a, 62b; 61a, 61b). L'extrémité distale du deuxième organe tubulaire est munie d'une aiguille (64) apte à s'étendre depuis l'extrémité distale du premier organe tubulaire. L'extrémité proximale du deuxième organe tubulaire est verrouillable par rapport à l'extrémité proximale du premier organe tubulaire. Le deuxième organe tubulaire possède une force de colonne lors de son verrouillage au sein du premier organe tubulaire pour limiter le recul du deuxième organe tubulaire par rapport au premier organe tubulaire lors de la ponction du tissu par l'aiguille.
