Abstract

L'invention concerne un surtube comprenant : une partie saillante de maintien d'espace formée pour faire saillie à partir de la surface externe de l'extrémité avant du surtube de telle sorte que même une lésion ayant un diamètre relativement grand, par laquelle l'endoscopie ne peut pas être effectuée, peut être simplement ligaturée puis incisée ; une partie de ligature de bande pour ligaturer une partie de lésion, au moyen de chaque bande, au niveau de la surface extérieure de l'extrémité avant du surtube ; et un capuchon de guidage disposé de façon à pouvoir être fixé à/détaché de la partie saillante de maintien d'espace, ce qui permet à son extrémité avant de focaliser la partie de lésion à ligaturer tout en protégeant la partie de ligature de bande. Par conséquent, une opération de la lésion ayant le diamètre relativement grand, par lequel une endoscopie ne peut pas être effectuée, peut également être effectuée de manière simple, pratique et rapide sans incision.
