Sacral nerve stimulation system

Abstract

The invention discloses a sacral nerve stimulation system, which comprises an implanted nerve stimulator, a stimulator programmed controller and a stimulating electrode, wherein the implanted nerve stimulator comprises a MCU (micro-programmed control unit) control module, a special chip, a protection circuit module, a power management module and a radio frequency communication module; the stimulator programmed controller comprises an ARM control module, a USB communication module, a charger module, a medical implanted equipment special communication module, a storage module, a display module and a key module; the stimulating electrode is connected to the special chip; and sacral nerves are directly stimulated after a stimulating pulse is received. The implant stimulator disclosed by the invention, by generating lasting electric pulse, can conduct electric stimulation on target nerves in a plurality of parts; the implant stimulator is controlled by the stimulator programmed controller in vitro; and the stimulation system achieves a satisfying effect when applied to such fields as uracratia, urinary retention, Parkinson, spinal neuralgia, peripheral electrical stimulation therapy and the like.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a sacral nerve stimulation system. 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 ca...

Problems solved by technology

In addition, it will be possible to treat spastic bladder by this method without the need for posterior rhizotomy of the sacral nerve

[0004] The general sacral nerve stimulation system uses different frequency bands, often causing interference and ineffective control; the layout of the external part and the implanted part is not clear; the communication between the two has invalid problems
