The woven mesh tube 200 is sleeved on the periphery of the inner tube 100, and the outer coating 300 is formed on the periphery of the woven mesh tube 200 through a plastic dipping process or a plastic spraying process, that is, the woven mesh tube 200 and the inner tube 100 are tightly wrapped by the outer coating 300, so that the woven mesh tube 200 is fixed relative to the inner tube 100. In view of the wrapping effect of the woven mesh tube 200 and the outer covering layer 300, the torsion resistance of the inner tube 100 can be improved, that is, when one end of the inner tube 100 is twisted, the other end of the inner tube 100 can generate expected twisting change, and the phenomenon that the inner tube 100 is randomly bent due to the influence of self materials, structures and the like to influence the transmission of twisting effect is avoided.
In the embodiment of the present application, the inner tube 100 may include at least one of a straight tube section and a spiral tube section, and the structure of the inner tube 100 may be determined according to a specific application scenario of the endoscope, which is not limited in the embodiment of the present application; for example, for an endoscope insertion tube for bronchial use, both ends of the inner tube 100 may be straight tube sections, and the middle section of the inner tube 100 may be a spiral tube section.

In the plastic dipping process, the situation that the radial size of the part is larger due to the fact that a large amount of plastisol is locally adhered to the substrate possibly exists, so that the normal use of the endoscope insertion tube is influenced, and if the endoscope insertion tube cannot be twisted normally, the change is caused. Therefore, in a further technical solution, the processing method may further include:
