Abstract

The invention provides a sacral nerve stimulator which comprises an external controller and an implanted stimulator which is implanted into the body. The implanted stimulator comprises a transceiver circuit, a single-chip microcomputer, a stimulation pulse generating module and an electrode bundle. The electrode bundle comprises at least two electrodes. The end of each electrode is provided with a stimulation point which is used for contacting with the sacral nerve, and furthermore two electrodes in the electrode bundle are working electrodes. The external controller and the implanted stimulator perform bidirectional communication in a wireless manner. The sacral nerve stimulator can stimulate the sacral nerve according to a parameter which is preset by a user for treating frequent urination and urgent urination and realizing controlled urination, and furthermore can acquire sacral nerve electric signals and tissue impedances for mastering an internal practical physiological condition of patient body.

Description

technical field [0001] The present invention relates to a nerve stimulator, in particular to a sacral nerve stimulator. 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 sacral nerve S2\S3\S4 can affect the action of bladder detrusor and external urethral sphincter, so that the use of appropriate stimulation signals can inhibit the hyperreflexia of bladder detrusor and achieve the purpose of relieving urinary incontinence; A specific stimulation pulse sequence can be used to stimulate the coordinated action of the bladder detrusor and the external urethral sphincter to achieve controlled voiding. [0003] The existing sacral nerve stimulation products or technol...
