[0002] At present, the existing medical endoscope cables have an overall hard feel and are not soft enough. Doctors feel bad when using them, and they are prone to bending and difficult to restore after multiple uses. Since these endoscope cables are reused, if the cables are deformed after a period of use, it will cause inconvenience in subsequent use and be detrimental to doctors' operations.

[0003] Therefore, a flexible cable for endoscope is designed to solve the above problems.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the utility model and for the convenience of understanding by those skilled in the art.

[0016] Furthermore, the filler 2 is an insulating sheath containing bulletproof wire inside; when the diameter of the core wire 2 is smaller than the diameter of the core wire 1, a single core wire 2 and two fillers 2 together form a unit, and the unit is arranged between the two core wires 1. In this solution, the bulletproof wire is filled in the insulating sheath to make the insulating sheath softer; the insulating sheath is filled between the core wire 1 and the core wire 2 to prevent the part of the wire body from sinking, and the insulating sheath only needs to be filled in the position where the core wire 2 is, so that the whole can be more rounded.

[0017] Furthermore, the signal shielding unit is wrapped outside the wrapping tape 2; the signal shielding unit includes a shielding layer 1 and a wrapping tape 3 arranged outside the shielding layer 1. In this solution, the shielding layer can play a shielding effect, and the wrapping tape can play an insulating and fixing role, so that the wrapped internal structure is more rounded.
