Summary:[Problem] To provide an outer sleeve tube that can be held in a fixed manner in a desired curved-shape, and a treatment tool having the outer sleeve tube. [Solution] This outer sleeve tube (3) is characterized by being provided with the following: a curving member (10) having curving segments (13) that are formed so as to be able to be accommodated in an annular and narrow cylindrical member (9) and that are disposed at two fixed segments fixed in the cylindrical member (9) and disposed between the fixed segments, and that can be curved in a direction that intersects the longitudinal direction of the curving portions, and the curving member causing the cylindrical member (9) to be curved in accordance with the curving segments (13) in a direction intersecting the longitudinal direction; an angle adjusting member (20) that can adjust the curvature angle of the curving segments (13); and an angle maintaining mechanism (30) that can maintain at any angle of curvature the curving segments (13) that have been curved by the angle adjusting member (20).  La présente invention vise à proposer un tube de manchon externe, qui peut être maintenu de façon fixe dans une forme incurvée souhaitée, et un outil de traitement ayant le tube de manchon externe. A cet effet, l'invention concerne un tube de manchon externe (3) qui est caractérisé en ce qu'il comprend : un élément de courbure (10) ayant des segments de courbure (13) qui sont formés de façon à pouvoir être reçus dans un élément cylindrique annulaire et étroit (9), et qui sont disposés sur deux segments fixes fixés dans l'élément cylindrique (9) et disposés entre les segments fixes, et qui peuvent être incurvés dans une direction qui coupe la direction longitudinale des parties de courbure, et l'élément de courbure amenant l'élément cylindrique (9) à s'incurver en fonction des segments de courbure (13) dans une direction coupant la direction longitudinale; un élément d'ajustement d'angle (20) qui peut ajuster l'angle de courbure des segments de courbure (13); et un mécanisme de maintien d'angle (30) qui peut maintenir à n'importe quel angle de courbure les segments de courbure (13) qui ont été incurvés par l'élément d'ajustement d'angle (20).
