Abstract: The present disclosure provides a bending section for a disposable endoscope. The bending section comprises a plurality of pull wire locating rings, which are made of a flexible material. Each of the pull wire locating rings has two opposing side walls defining a pull wire perforation therein respectively, the pull wire perforation running through the side wall. The pull wire locating rings are hinged end to end in series to form a bendable flexible tube structure. The pull wire perforations in the pull wire locating rings are communicated in sequence to define a pull wire channel located in the side walls of the pull wire locating rings. The pull wire locating ring has one end surface defining a notch. The present disclosure has the flexibility greatly enhanced and is more sensitive to pull.
