Abstract

L'invention concerne un dispositif d'agrafage chirurgical allongé qui comprend : un corps principal, un support de cartouche (1), une cartouche (3) et une enclume (2) qui sont placés à une extrémité distale du corps principal, et une tige d'entraînement d'outil (6) mobile. La tige d'entraînement d'outil (6) entraîne un outil (7) et un bloc de tir (5) à déplacer. Le support de cartouche (1) est muni avec faculté de pivotement d'un bloc de sécurité (8) pour empêcher un second tir. Le bloc de sécurité (8) est placé à l'extrémité distale de la tige d'entraînement de l'outil (6) et de l'outil (7). Lorsque le dispositif est à l'état initial et après que le tir ait été effectué, le mouvement de la tige d'entraînement de l'outil (6) et de l'outil (7) est empêché de l'extrémité proximale à l'extrémité distale du dispositif d'agrafage chirurgical allongé. La fermeture du dispositif d'agrafage chirurgical allongé peut être empêchée lorsque le médecin ne remplace pas la cartouche (3) tirée ou que la cartouche (3) n'est pas montée en place, de façon à éviter un accident médical, ou de léser le tissu normal ; en outre, la structure est simple et efficace.
