超声波内窥镜
摘要：
本发明提供在两管腔之间之间形成瘘孔的方法、超声波内窥镜、带球囊的导管、磁体留置器具和磁体组件。该瘘孔形成方法用于在第1管腔和第2管腔之间形成瘘孔，其包括以下步骤：用穿刺针自上述第1管腔内通过上述第1管腔的壁面、上述第2管腔的壁面穿刺至上述第2管腔内；将上述穿刺针配置在中心轴线的位置，用线圈针在上述穿刺针的周围自上述第1管腔向第2管腔进行穿刺，使第1管腔和第2管腔相连接；在使上述第1管腔和第2管腔相连通着的状态下维持上述线圈针；在上述线圈针的内侧形成瘘孔。
摘要（英）：

A fistulectomy method of forming a fistula between a first duct and a second duct includes sticking a puncture needle into the second duct from the inside of the first duct through a wall surface of the first duct and a wall surface of the second duct, arranging the puncture needle at a position of a central axis and sticking a coil needle around the puncture needle from the first duct toward the second duct to couple the first duct with the second duct, maintaining the coil needle in a state where the first duct communicates with the second duct, and forming the fistula on an inner side of the coil needle.
