Title
(EN) TRIGGER ASSEMBLY FOR TYMPANOSTOMY TUBE DELIVERY DEVICE
(FR) ENSEMBLE DE DÉCLENCHEMENT POUR DISPOSITIF DE POSE DE DRAINS TRANS-TYMPANIQUES
Abstract
(EN)
A tympanostomy tube delivery device comprises a shaft assembly, a pressure equalization tube, and a trigger assembly. The shaft assembly comprises a cannula and a pusher operable to translate relative to the cannula. The pressure equalization tube is positioned within the shaft assembly. The pusher is operable to drive the pressure equalization tube out of the shaft assembly. The trigger assembly includes a pair of pushbuttons and a linkage. The pushbuttons are secured to the device via living hinges and are selectively pivotable. The linkage is configured to engage the delivery device to thereby selectively prevent actuation of the delivery device. The pivoting of one or both the pushbuttons is configured cause the linkage to collapse so as to disengage the delivery device and thereby actuate the delivery device.
(FR)
L'invention concerne un dispositif de pose de drains trans-tympaniques qui comprend un ensemble arbre, un drain d'égalisation de pression et un ensemble de déclenchement. L'ensemble arbre comporte une canule et un poussoir pouvant être actionné pour se déplacer en translation par rapport à la canule. Le drain d'égalisation de pression est positionné à l'intérieur de l'ensemble arbre. Le poussoir peut fonctionner pour pousser le drain d'égalisation de pression hors de l'ensemble arbre. L'ensemble de déclenchement comprend une paire de boutons-poussoirs et un élément de liaison. Les boutons-poussoirs sont fixés au dispositif par l'intermédiaire de charnières vives et peuvent sélectivement pivoter. L'élément de liaison est configuré pour venir en prise avec le dispositif de distribution pour ainsi empêcher sélectivement l'actionnement du dispositif de pose. Le pivotement de l'un ou des deux boutons-poussoirs est configuré pour faire replier l'élément de liaison de manière à libérer le dispositif de pose et, ainsi, l'actionner.
