An implantable sacral nerve stimulator

Abstract

The invention discloses an implantable sacral nerve stimulator, which includes an MCU control module, a dedicated chip, a protection circuit module, a power management module and a radio frequency communication module. The MCU control module analyzes and processes signals received from the radio frequency communication module, Output the control signal to a dedicated chip; the dedicated chip includes a digital circuit interface, a stimulus measurement circuit and a stimulating electrode interface; the protection circuit module performs overvoltage and overcurrent protection on the output of the power management module, and performs electrostatic protection and electromagnetic interference on the output of the dedicated chip Noise reduction; the power management module can output multi-level voltages to dedicated chips; the radio frequency communication module receives command signals from the outside, denoises and amplifies them, and outputs them to the MCU control module. The present invention generates continuous electrical pulses to electrically stimulate target nerves at multiple locations, and achieves satisfactory effects in the fields of urinary incontinence, urinary retention, Parkinson's, spinal neuralgia, peripheral electrical stimulation and the like.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an implanted sacral nerve stimulator. Background technique [0002] For patients with spinal cord injury, bladder detrusor hypertonic reflex and detrusor-sphincter synergy disorder often occur, causing urinary retention and kidney damage. In the past, drug treatment, intermittent catheterization and various surgical treatments were often used And so on, but there are disadvantages such as unsatisfactory effect, long treatment cycle, and many complications. Until the advent of the sacral nerve root stimulator, it is based on the principle that the biological characteristics of the detrusor and sphincter muscles are different. When using intermittent pulse stimulation, it can During the two stimulation periods, urination occurs due to the continuous increase in the intravesical pressure, but this urination method belongs to an artificial voiding mode, and the stimulation parameters...
