The invention relates to the technical field of
nerve stimulation, in particular to a miniature implantable
spinal nerve stimulator which comprises an
electrode, a stimulator body and a
control system. The
electrode, the stimulator body and the
control system operate in a matched mode, the
electrode and the stimulator body are integrally connected and arranged without an extension wire, the stimulator body sinks to the lower portion of a spine
spinous process, and an upper end wire is flush with other spinous processes of the spine; the
control system comprises a main controller unit, a
radio frequency unit, a channel decoding unit, a
transmitter unit, a power divider / synthesizer unit, a main
power supply unit, an
energy storage unit, an electrical stimulation unit, an array electrode unit and a
posture recognition unit. The miniature
spinal cord nerve stimulator is implanted in the early stage of
spinal cord injury by combining
spinal cord nerve
decompression operation and spinal fixation operation, the size of the stimulator is small, the electrode lead is short, no
implant protrusion phenomenon exists after operation, the golden
window period after
spinal cord injury is fully utilized, favorable conditions are created for
spinal cord injury rehabilitation, and the
rehabilitation effect is improved.
