Title
(EN) HYBRID BLUNT CANNULA WITH PUNCTURE NEEDLE ASSEMBLY
(FR) CANULE ÉMOUSSÉE HYBRIDE AVEC ENSEMBLE AIGUILLE DE PONCTION
Abstract
(EN) A hybrid blunt cannula with puncture needle assembly provides an outer cannula member comprising a needle channel, an eye, a stopper member disposed at the second end of the cannula member, and an inner needle disposed inside the needle channel and coupled to buttons. The buttons follow a translation path between a static position and an insertion position. The static position enables the free end of inner needle to be proximal to the second end of the outer cannula member, and within the needle channel. The insertion position enables the free end of the inner needle to be proximal to second end of the outer cannula member and partially outside of the outer needle's channel. The free end of inner needle is operable to penetrate the stopper member while in insertion position for discharge of a liquid through the eye.
(FR) L'invention concerne une canule émoussée hybride dotée d'un ensemble aiguille de ponction, qui fournit un élément de canule externe comprenant un canal d'aiguille, un oeillet, un élément d'arrêt disposé au niveau de la seconde extrémité de l'élément de canule, et une aiguille interne disposée à l'intérieur du canal d'aiguille et couplée à des boutons. Les boutons suivent un trajet de translation entre une position statique et une position d'insertion. La position statique permet à l'extrémité libre de l'aiguille interne d'être proximale à la seconde extrémité de l'élément de canule externe, et à l'intérieur du canal d'aiguille. La position d'insertion permet à l'extrémité libre de l'aiguille interne d'être proximale à la seconde extrémité de l'élément de canule externe et partiellement à l'extérieur du canal de l'aiguille externe. L'extrémité libre de l'aiguille interne peut être actionnée pour pénétrer dans l'élément d'arrêt tout en étant en position d'insertion pour la décharge d'un liquide à travers l'oeil.
