Abstract

Font l'objet de cette invention un instrument chirurgical susceptible d'être utilisé avec une seule main et son procédé de fonctionnement. Ledit instrument chirurgical comprend un appareil d'exécution (300), un corps de connexion intermédiaire (200) et une commande (100), l'appareil d'exécution (300), le corps de connexion intermédiaire (200) et la commande (100) étant successivement connectés. L'appareil d'exécution (300) comprend un ensemble cartouche d'agrafe (3002), un ensemble enclume d'agrafe (3001) et un ensemble d'entraînement (3003). La commande (100) comprend, quant à elle, un mécanisme de déclenchement d'allumage, un mécanisme de prévention d'allumage et un mécanisme de remise à zéro automatique. L'instrument chirurgical selon l'invention possède une fonction de remise à zéro automatique permettant à l'appareil d'exécution (300) dudit instrument chirurgical, d'une part, de maintenir un tissu lorsque le mécanisme de prévention d'allumage n'a pas encore démarré et que le corps médical a mis en marche le mécanisme de déclenchement d'allumage (111) et, d'autre part, de revenir à la position initiale et de relâcher le tissu maintenu lorsque le corps médical desserre le mécanisme de déclenchement d'allumage (111). Ladite fonction de l'instrument chirurgical non seulement facilite le réglage de l'agrafeuse en ne nécessitant qu'une seule main pour maintenir le tissu dans une certaine position, elle est aussi avantageuse pour augmenter l'uniformité de l'épaisseur du tissu maintenu par le biais du maintien répété de la même partie du tissu, ce qui a pour effet d'améliorer l'agrafage et la coupe de tissus.
