    • A treatment tool is made to protrude at an appropriate position with respect to an endoscope while maintaining a high flexibility. Provided is a medical tube (1) including: a first lumen (4) that forms an endoscope channel by penetrating through a tube main body (2), which is constituted of a material possessing flexibility, in a longitudinal-axis direction; a plurality of second lumens (5 and 5a) that are capable of forming treatment-tool channels by penetrating through the tube main body (2) in the longitudinal-axis direction at a periphery of the first lumen (4) with spacings therebetween in a circumferential direction; a first indicator (12) that is provided on an inner surface in the vicinity of a distal end of the first lumen (4) and that specifies a circumferential-direction position of any one of the second lumens (5 and 5a) with respect to the first lumen (4); and a second indicator (13) that is provided at a proximal end of the tube main body (2) and that indicates the second lumen (5a) specified by the first indicator (12).
    • 处理工具相对于内窥镜在适当的位置突出,同时保持高度的柔性。 本发明提供一种医疗用管(1),该医疗用管(1)具备:第一管腔(4),其在纵轴方向贯通由具有挠性的材料构成的管主体(2) 多个第二管腔(5和5a),所述多个第二管腔(5和5a)能够通过在第一管腔(4)的周边沿纵轴方向穿过管主体(2)而形成治疗工具通道, 圆周方向; 第一指标(12),其设置在所述第一管腔(4)的前端附近的内表面上,并且指定所述第二管腔(5和5a)中的任一个相对于所述第二管腔 第一腔(4); 以及第二指示器(13),其设置在所述管主体(2)的基端,并且指示由所述第一指示器(12)指定的所述第二管腔(5a)。
