Abstract: Provided is a segmented bending section assembly for a disposable ureteroscope, including a bending sectional tube, elastic tubes, and traction cables. Multiple U-shaped limiting grooves arranged in an axial direction of the bending sectional tube are formed in a side wall of a tail portion of the bending sectional tube. An end portion of each of the elastic tubes abuts against a bottom wall of each U-shaped limiting groove, a side wall of the elastic tube abuts against an inside wall of the U-shaped limiting groove, and the elastic tube is welded to the U-shaped limiting groove. A tube body of the bending sectional tube is internally provided with multiple wire-passing channels for the traction cables to pass through, and the traction cable penetrates through the elastic tube and the wire-passing channel and then are fixedly connected to a front end of the bending sectional tube.
