Abstract

The invention provides a wireless charging device and a sacral nerve stimulation system thereof. A charging receiving coil is arranged in an implant. When the electric quantity of a built-in battery is insufficient, an extracorporeal charging transmitting coil is arranged at the position matched with the charging receiving coil, and wireless charging for the built-in battery is performed through coupling between the coils. Besides, an intracorporeal charging control unit is also arranged in the implant to detect the electric quantity of the built-in battery and transmit the detected electric quantity information to the outside through the first antenna and the second antenna of the sacral nerve stimulation system so as to prompt a user to charge the built-in battery. Furthermore, when the built-in battery is charged, the charging receiving coil also supplies power to stimulating electrodes so as to ensure that the stimulating electrodes can still perform current stimulation on sacral nerves in charging. The risk of replacing the intracorporeal battery can be reduced for patients and the safety of the sacral nerve stimulation system can be increased.

Description

technical field [0001] The invention relates to a nerve stimulator, in particular to a wireless charging device capable of wirelessly charging an implant body and a wirelessly charging implantable sacral nerve stimulation system. Background technique [0002] Bladder diseases such as urinary incontinence and frequent urination are usually caused by damage to the nervous system and spinal cord. Medical research and practice have confirmed that applying electrical stimulation to the relevant nerves is an effective treatment method. Many studies have shown that stimulating the anterior root of the sacral nerve can affect the action of the bladder detrusor and the external urethral sphincter, so that the use of appropriate stimulation signals can inhibit the hyperreflexia of the bladder detrusor and achieve the purpose of relieving urinary incontinence; specific stimulation can also be used Pulse sequence to stimulate the coordinated action of bladder detrusor and external ureth...
