Embodiment Construction

[0047] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0048] like figure 1 As shown, the implantable electrical stimulation device provided by the present invention includes an external controller and an implanted stimulator, and the external controller controls the implanted stimulator by means of wireless energy transmission.

[0049] The external controller includes a power supply module, a control module, a drive module, a feedback signal acquisition module, a transmission coil, and a relay compensation coil. The working process is as follows: the power supply module supplies power to the control module and the drive module; the control module outputs the control signal to the drive module, receives the feedback signal from the feedback signal acquisition module, and adjusts the control signal; the drive module receives the control signal from the control module, drives the transmission The coil generat...

Abstract

The invention discloses an implanted electrical stimulation device based on magnetic coupling resonance wireless energy transmission. The device comprises an external controller and an implanted stimulator, the external controller and the implanted stimulator are of wireless energy transmission, the external controller comprises a power supply module, a control module, a driving module, a feedbacksignal acquisition module and a transmit coils, and the implanted stimulator comprises a receiving module, a rectifier circuit module, a voltage stabilizing circuit module and a stimulating electrode. According to the implanted electrical stimulation device provided by the present invention, the implanted stimulator implanted in the human body no longer needs power supply unit such as a battery,so that the volume of the stimulator can be greatly reduced, which is beneficial to realizing the overall encapsulation of the electric stimulator and reducing safety risk caused by electrode breakageand battery liquid leakage.

Description

technical field [0001] The invention belongs to the fields of biomedicine and wireless energy transmission, in particular to an implantable electrical stimulation device based on magnetic coupling resonance wireless energy transmission. Background technique [0002] At present, neuromodulation methods represented by deep brain electrical stimulation, transcranial electrical / magnetic stimulation, peripheral nerve / muscle function electrical stimulation and other technologies have been applied in clinical disease treatment. Compared with non-invasive technical means, invasive methods represented by passive electrical stimulator implantation (such as deep brain electrical stimulator) can usually place the stimulation source directly into the desired target area, so that the stimulation source can be directly placed inside the desired target area. Accuracy is greatly improved. Since the source of the release stimulus is very close or located in the center of the target area, the...
