External energy controller of nerve stimulation system

Abstract

The invention discloses an external energy controller of a nerve stimulation system. Through a radio frequency way, electric energy is transmitted to an implantable nerve stimulator through a radio frequency way, and the external energy controller and the implantable nerve stimulator communicate. The external energy controller of the nerve stimulation system comprises an input device, an antenna module, a display device, a storage unit and a control unit, wherein the external energy controller receives information through the input device; the antenna module and the stimulator antenna of the implantable nerve stimulator carry out radio frequency coupling so as to send an input signal containing electric energy and control information to the implantable nerve stimulator, and instruction data can be received from the implantable nerve stimulator; the display device is used for displaying the data, the instruction and the input information; the storage unit stores an operation program, the input information and the data; and the control unit is independently connected with the input device, the antenna module and the display device so as to control operation of the whole external energy controller. The external energy controller of the nerve stimulation system can overcome treatment failure caused by short-time communication interruption, and the implantable nerve stimulator can obtain stable power supply.

Description

technical field

[0001] The invention relates to an external energy controller of a nerve stimulation system, which forms a nerve stimulation system together with an implanted nerve stimulator with a main control chip through radio frequency communication. Background technique

[0002] Neurostimulation systems incorporating implantable neurostimulators have been widely used in the medical field. In this system, an implantable neurostimulator is implanted in the patient to achieve treatment of the affected area.

[0003] Traditional implantable neurostimulators require their own batteries for power. When the battery dies, the neurostimulator implanted in the patient needs to be removed so the battery can be reinstalled. In addition, when the doctor needs to change the treatment plan, the neurostimulator implanted in the patient also needs to be removed in order to reconfigure the treatment plan. The treatment scheme includes, for example, the pulse width and frequency of st...
