Embodiment Construction

[0021] The present invention will be further explained below in conjunction with the accompanying drawings.

[0022] like figure 1 As shown in the figure, an implantable electrical stimulation device for controlling the motor function of limbs includes a body surface detection electrode 1, a signal processing circuit 2, a communication channel 3, an excitation signal generation circuit 4, an implanted stimulation electrode circuit 5, and a myoelectric signal recording Device 6 with programming replay function. The body surface detection electrode 1 is used to collect body surface myoelectric action potential signals at corresponding collection points during healthy limb movement and send them to the signal processing circuit 2 . The signal processing circuit 2 is used to process the body surface myoelectric action potential signal to obtain multiple nerve or myoelectric characteristic signals. The communication channel 3 is used to send multiple nerve or myoelectric characte...

Abstract

The invention discloses an implantable electrostimulation limb movement function regulation device. A body surface detecting electrode is adopted to collect body surface myoelectric action potential signals during movement at a site corresponding to a healthy limb, the body surface myoelectric action potential signals are amplified and filtered by a signal processing circuit, pulse amplitude modulation technology is utilized to modulate the body surface myoelectric action potential signals onto high-frequency carriers, high-frequency signals after being modulated are applied onto an in-vitro coil to generate a high-frequency electromagnetic field, the in-vitro coil is coupled on a coil of an in-vivo implantable electrode to generate high-frequency voltage, stimulating voltage pulse is formed after amplitude detection, the stimulating voltage pulse is applied onto an in-vivo electrode contacting with a controlled nerve bundle, and action potential is excited in the nerve bundle so as to realize movement of a paralytic limb. The body surface electrode is pasted on the healthy limb to acquire movement related myoelectric signals, so that the device has the advantage of non-intrusion; the in-vivo implantable electrode is adopted for functional electrostimulation, so that the device has the advantages of low stimulation voltage, high control sensitivity and high selectivity.

Description

technical field [0001] The invention belongs to the intersecting field of traditional medicine, rehabilitation medicine and electronic science, and relates to an implanted electrical stimulation regulating device for limb motor function. Background technique [0002] In the past ten years, the inventors have studied microelectronic neural bridges related to nerve signal regeneration and functional reconstruction, and have formed the goal of realizing limb nerve function regeneration by bridging interrupted nerve channels. In the invention patent of ZL200510135541.6, a "Microelectronic System Assisted Nerve Channel Function Restoration Method and Device" is proposed, which is used for channel bridging, signal regeneration and functional reconstruction of damaged spinal cord nerves. The characteristic of this method is to restore the function of damaged nerve bundles or nerve fibers by means of microelectronics. The disadvantage is that surgery is required to implant the micro...
