Its basic principle is to send electrical pulse signals to the spinal nerves through implanted electrodes. These signals can regulate nerve activity, interfere with and block the transmission of pain signals to the brain, and also stimulate nerves to promote lower limb muscle activity and sensory recovery.

[0003] The Chinese patent with publication number CN112569471 B proposes a neural electrical stimulation device, including a front connector, an electrode wire, a rear connector, an extension wire and a limiting structure.
