An endoscope flexible tube having a cylindrical flexible tube base that has flexibility and a resin layer that coats the flexible tube base includes the resin layer, which is a single layer or multiple layers of two or more layers, comprises a layer A which comprises: polyester elastomers, at least one of polyurethane elastomers or polyamide elastomers, and both a hindered phenol compound and a hindered amine compound, wherein the content of the polyester elastomers in the layer A is 55 mass % or more.

Flexible tube for endoscopes and method for producing same

A method for washing a treatment tool stand of an endoscope using a stand washing tool having a first washing member formed to a first height position and a second washing member formed to a second height position lower than the first height position. The washing method comprises a first washing member inserting step of inserting the first washing member into a gap between a stand storage wall section of the endoscope and the treatment tool stand; a second washing member abutting step of making the second washing member abut against a treatment tool guide surface of the treatment tool stand; and a stand washing tool moving step of moving the stand washing tool along the treatment tool guide surface in a state where the first washing member is inserted into the gap and the second washing member is made to abut against the treatment tool guide surface.
