Implantable sacral nerve stimulator

Abstract

The invention discloses an implantable sacral nerve stimulator which comprises an MCU control module, a special chip, a protecting circuit module, a power source management module and a radio frequency communication module. The MCU control module analyzes and processes signals received from the radio frequency communication module and outputs the control signals to the special chip. The special chip comprises a digital circuit port, a stimulus measuring circuit and a stimulating electrode port. The protecting circuit module carries out over-voltage and over-current protection on output of the power source management module and carries out static protection and electromagnetic interference and noise reduction on output of the special chip. The power source management module can output multiple levels of voltage to the special chip. The radio frequency communication module receives instruction signals from the outside of the body, and outputs the signals to the MCU control module after carrying out denoising and amplifying. By generating continuous electric pulses, electric stimulation is carried out on target nerves at multiple parts, and the satisfactory effect is obtained in the application to the fields of urinary incontinence, urinary retention, Parkinson, spinal cord neuralgia, periphery electric stimulation treatment 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...
