Abstract
A bending tube of an insertion appliance includes a first region including a first plurality of slits, a second region provided proximally relative to the first region and including a second plurality of slits, and a guiding surface on an inner circumferential surface of the bending tube, the guiding surface extending in a circumferential direction, and including a channel configured to slidably house a wire. Each slit of the first plurality of slits is at different position in the circumferential direction, and at different positions in a longitudinal direction. Each slit of the second plurality of slits is provided at different position in the circumferential direction, and at different position in the longitudinal direction. The first plurality of slits is distributed over a first angle in the circumferential direction, and the second plurality of slits is distributed over a second angle smaller than the first angle in the circumferential direction.
