[0014] Example

[0015] In order to solve the above technical problems, this embodiment provides a medical image signal transmission line, such as Figure 1As shown, the coaxial line 10 includes a plurality of core wires 20, and a tape layer 30 and an outer layer 40 sequentially wrapped around the outer periphery of the coaxial line 10 and the core wire 20. The coaxial line 10 includes a first conductor 11 and at least five layers of PTFE foam raw tape 12 wrapped around the first conductor 11. An aluminum foil layer 13, a first braided layer 14 and a first inner layer 15 are sequentially wrapped around the outer periphery of the PTFE foam raw tape 12. By wrapping the tape layer 30 and the outer layer 40 around the coaxial line 10 and the core wire 20, the internal structure of the transmission line can be protected. While ensuring the roundness of the transmission line's shape, the first conductor 11 is coated with at least five layers of PTFE foam raw tape 12 to further improve the physical properties of the insulation layer and ensure signal transmission stability. The PTFE foam raw tape 12 is insulated by tape wrapping, using five layers of PTFE foam raw tape to replace the insulation layer. PTFE foam raw tape has an extremely low friction coefficient, good wear resistance, and excellent chemical stability, which can improve the flexibility of the transmission line, thereby extending the service life of the transmission line drag chain. By coating the PTFE foam raw tape 12 with an aluminum foil layer 13, a first braided layer 14, and a first inner layer 15, it can shield the coaxial line 10 and the core wire 20, ensuring the stability of the transmission signal, improving the physical properties of the transmission line to pass the required drag chain test, and extending the service life of the transmission line drag chain.

[0016] Specifically, the core wire 20 includes a second conductor 21, an insulating layer 22 coated on the second conductor 21, a second braided layer 23 and a second inner layer 24. By coating the second conductor 21 with the insulating layer 22 and the second braided layer 23, the core wire 20 and the coaxial cable 10 can be shielded to ensure the stability of the transmission signal. By coating the second conductor 21 with the second inner layer 24, the internal structure of the core wire can be protected, and the roundness of the core wire 20 can be maintained, thereby achieving a shielding effect between the core wires 20.

[0017] Furthermore, the first conductor 11 and the second conductor 21 are formed by twisting a plurality of silver-plated copper wires.

[0018] In the above scheme, the outer layer 40 is composed of an elastomer TPU material. By using the elastomer TPU to form the outer layer 40, the physical properties of the outer layer can be effectively improved, thereby improving the softness and strength of the wire, thereby improving the service life of the wire, achieving improved softness and strength of the wire, and further improving the service life of the wire.

[0019] In order to ensure that the shape of the wire is round and tight, as a preferred embodiment, the wrapping layer 30 is wrapped around the coaxial line 10 and the core wire 20 in the S direction. By wrapping the wrapping layer 30 around the coaxial line 10 and the core wire 20 in the S direction, the cable is formed in one go during the wrapping process, so that the wire can be ensured to be round and tight during the twisting process, thereby ensuring that the shape of the wire is round and tight.
