A threaded syringe (10) provides a mechanism by which a clinician can deliver a viscous fluid through a relatively small lumen and can obtain tactile or audible feedback of delivery. The threaded syringe (10) allows for delivery of more viscous fluids with less forces and/or allows for more controlled delivery. The syringe includes a syringe barrel (12) and a sliding member (14) positioned on the proximal end of the syringe barrel (12). The sliding member (14) has a first threaded hole (28) and a second hole (30). The sliding member (14) is sliding on the syringe barrel (12) between a first position at which the first threaded hole (28) is aligned with the syringe barrel (12) for precise delivery of a material from the syringe and a second position at which the second hole (30) is aligned with the syringe barrel (12) for filling of the syringe or to stop bleed out.
L'invention concerne une seringue filetée (10) qui comporte un mécanisme permettant au praticien d'administrer un fluide visqueux via une lumière de taille relativement réduite et de recevoir en rétroaction une information tactile ou audible. La seringue filetée (10) assure l'administration de fluides plus visqueux selon des forces réduites et/ou permet une administration plus contrôlée. La seringue comprend un cylindre (12) et un élément coulissant (14) placé à l'extrémité proximale du cylindre (12). L'élément coulissant (14) comporte un premier trou fileté (28) et un second trou (30). L'élément coulissant (14) coulisse sur le cylindre (12) entre une première position à laquelle le premier trou fileté (28) est aligné avec le cylindre (12) pour l'administration précise de matériau depuis la seringue, et une seconde position à laquelle le second trou (30) est aligné avec le cylindre (12) pour le remplissage de celle-ci ou pour l'arrêt de l'écoulement.
