Abstract

La présente invention concerne un outil multi-procédure pour une couche sous-muqueuse endoscopique qui exécute une pluralité de modes dans un dispositif par l'intermédiaire d'un module multi-procédure, et résout les problèmes qui existent avec les outils chirurgicaux classiques pour la couche sous-muqueuse endoscopique, caractérisé en ce qu'un cathéter de pulvérisation qui est généralement un cathéter destiné à pulvériser un pigment, un couteau de marquage, une aiguille d'injection, un couteau d'incision, un couteau d'hémostase et de nettoyage, et un couteau de délamination sont utilisés en alternance pendant l'opération. Cela demande beaucoup de temps d'acquérir les compétences nécessaires à l'utilisation des outils décrits précédemment. Cela demande également beaucoup de temps de remplacer la pluralité de couteaux, et le coût d'achat de la pluralité d'outils chirurgicaux est élevé. L'outil multi-procédure pour la couche sous-muqueuse endoscopique selon la présente invention comprend un module de commande, un module de tube, et un module multi-procédure. Ainsi, un mode de pulvérisation de pigment, un mode de marquage de lésion, un mode d'injection, un mode d'incision-hémostase-nettoyage, et un mode de délamination peuvent être exécutées sous le contrôle d'un mode de commande. En outre, une pression de pulvérisation d'eau peut être ajustée pour réaliser une opération de micro-incision, et simultanément, tous les modes tels que l'incision hémostatique et diverses injections peuvent être exécutées par une manipulation. Ainsi, même un non-expert peut facilement acquérir les compétences. Des sections fortement cintrées peuvent être également médicalement opérées, et des incisions verticales et des incisions tournantes peuvent être pratiquées. De plus, le temps et le coût d'opération peuvent être réduits au minimum.
