Abstract

La présente invention concerne, selon un mode de réalisation, un dispositif à agrafes chirurgicales. Le dispositif à agrafes chirurgicales comprend : une unité de chargement qui comporte un dispositif de coupe pour couper les tissus corporels et des agrafes pour fermer les sites d'incision ; et une unité de poignée pour commander le fonctionnement de l'unité de chargement, l'unité de chargement pouvant être attachée à l'unité de poignée et détachée de celle-ci. L'unité de poignée comprend une partie boîtier de poignée, une partie arbre d'entraînement, une partie poignée d'actionnement, une première partie de butée et une seconde partie de butée. La partie arbre d'entraînement est disposée à l'intérieur de la partie boîtier de poignée de manière à pouvoir effectuer un mouvement de va-et-vient d'arrière en avant. La partie poignée d'actionnement est disposée dans la partie boîtier de poignée de manière à pouvoir pivoter. La première partie de butée est disposée sur un côté de la partie arbre d'entraînement, et restreint sélectivement le mouvement vers l'avant de la partie arbre d'entraînement par déplacement dans la direction haut-bas par le mouvement de la partie poignée de commande. La seconde partie de butée est disposée sous la partie d'extrémité avant de la partie arbre d'entraînement de manière à pouvoir être levée et abaissée, et vient en contact étroit avec la surface inférieure de la partie arbre d'entraînement lorsqu'elle est levée.
