[0042] Further, based on the scheme that the cable includes 7 coaxial line unit groups; one coaxial line unit group includes 20 coaxial lines, and one coaxial line includes 7 cores, it is set that the core uses a 36AWG core;

[0043] Correspondingly, in this solution, the wire diameter of the cable used for medical ultrasound drive is 10.7±0.3 mm.

[0048] Based on any of the foregoing solutions, in one possible implementation manner, the characteristic impedance of the cable configured for medical ultrasound driving is 50 ohms.

[0049] Combination Figures 1 to 3 Based on any of the above solutions, in one possible implementation scheme, the cable includes:

[0050] 7 coaxial line unit groups 1 (A1-A7), the coaxial line unit group 1 is provided with a first sheath 2 and a second sheath 3;

[0051] A coaxial line unit group includes 20 coaxial lines 11, and each coaxial line 11 includes a core 111, an insulating layer 112, a shielding layer 113 and a sheath layer 114;

[0052] One coaxial line unit group 1 further includes a binding layer 4, and the binding layer 4 is used to bind the multiple coaxial lines 11 into a bundle.

[0054] In this solution, the cable design structure is optimized, and the outermost sheath (second sheath 3) of the cable is made of PVC material with good flexibility and white design;

[0055] Multiple coaxial lines are bound with nylon yarn, with 20 cores in a bundle (constituting a coaxial line unit group), which can be more clearly distinguished during processing;

[0056] The shielding layer 113 is made of tinned copper wire mesh, so that the cable has better overall flexibility and a smaller bending radius; the overall cable diameter is 10.7±0.3mm, which can save design space;

[0062] In this solution, silver-plated copper alloy is selected as the conductor of the wire core. The 36AWG wire core can meet the communication requirements and can be used in scenes with low rated current such as ultrasound and laser. The DC resistance of silver-plated copper alloy is smaller, the cable loss is lower, and the transmission efficiency is increased. The 70-core and 140-core integration is more suitable for multi-channel hard environments.

[0063] The outer layer uses tinned copper wire mesh to increase the shielding effect and better meet EMC design.
