Detailed ways

The following descriptions are only preferred embodiments of the present invention, which do not limit the protection scope of the present invention.

An embodiment, as shown in FIG. 1, a multi-core medical control wire, comprising an outer quilt 1, a wrapping tape 2 and a cable core assembly 3, the wrapping tape 2 includes a cable core assembly 3, an outer quilt 1 wraps the wrapping tape 2, and the cable core The assembly 3 includes a first layer of cable cores 31 and a second layer of cable cores 32, the first layer of cable cores 31 includes one first cable core 33, the second layer of cable cores 32 includes six second cable cores 33, and the first layer of cable cores 31 includes six second cable cores 33. The cable cores 31 are arranged in the middle, the second layer of cable cores 32 are distributed on the outside of the first layer of cable cores 31 in a circular array, and the inner side of the second layer of cable cores 32 abuts against the first layer of cable cores 31. The outer side of the cable core 32 is pressed against the wrapping tape 2; the inner side of each second cable core 33 is pressed against the first cable core 33, and the outer side of each second cable core 33 is pressed against the wrapping tape 2; the first cable core 33 and the second cable core 33 respectively include a conductor 331 and an insulating layer 332, and the insulating layer 332 wraps the conductor 331.
