Bending structure of endoscope

The utility model discloses a bending structure of an endoscope, which comprises a bending framework, the bending framework comprises a bending part which is integrally formed by injection molding, the bending part is formed by combining a plurality of bending blocks which are integrally formed by injection molding, and a plurality of through holes which can be penetrated by traction guide wires are arranged on the inner circumferential surface of the bending part. Hollowed-out cavities are formed between the bending blocks in the bending part, and the whole bending framework is made of a medical-grade elastic PC material. The whole structure is obtained through injection molding, a plurality of working procedures, process control and the like in the machining process are omitted, and the production efficiency is greatly improved; meanwhile, the whole product is of a symmetrical structure, injection mold drawing/demolding is facilitated, the injection molding difficulty of integral molding is reduced, the lar
