Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0026] In one embodiment of the present invention, as figure 1 Shown, the regulation method of the stimulation frequency of a kind of sacral nerve stimulator of the present invention comprises the following steps:

[0027] Set up two sets of stimulating electrodes;

[0028] Setting the stimulus change period, the stimulus change period is a change value;

[0029] sending low-frequency pulses to one group of stimulating electrodes, and sending high-frequency pulses to the other group of stimulating electrodes until the st...

Abstract

The invention discloses a method of regulating a stimulation frequency of a sacral nerve stimulator. The method comprises steps: two groups of stimulation electrodes are set; a stimulation changing period is set, wherein the stimulation changing period is a changing value; low-frequency impulses are transmitted to one stimulation electrode group and high-frequency impulses are transmitted to the other stimulation electrode group until the stimulation changing period is reached; in a next stimulation changing period, stimulation frequency signals of the two groups of stimulation electrodes are exchanged. The high-frequency and low-frequency combined electrical nerve stimulation is adopted to control contraction of bladder to empty the bladder, and generation of sphincter urethrae maladjusted contraction can also be avoided; the frequency amplitude in the low frequency part is changing, thereby avoiding fatigue on stimulation by nerve muscle; and only two stimulation points only need to be set, high-frequency and low-frequency stimulation is carried out alternatively at the two stimulation points, the problem of requiring multiple stimulation points is solved, and the operation difficulty is reduced.

Description

technical field [0001] The invention relates to the field of sacral nerve stimulators, in particular to a method for adjusting the stimulation frequency of the sacral nerve stimulator. Background technique [0002] Sacral nerve electrical stimulator, also known as bladder pacemaker, is a minimally invasive and reversible new therapy for bladder voiding dysfunction. Sacral nerve stimulation, also known as sacral neuromodulation, is a medical electrical stimulation therapy. In terms of voiding dysfunction, it mainly treats the symptoms of frequent urination, urgency, urge urinary incontinence, and non-obstructive urinary retention in patients who are ineffective or unable to tolerate conservative treatment (oral drugs, behavioral therapy). A programmable stimulator, the sacral nerve stimulator, is usually implanted subcutaneously, which connects to the sacral nerve through leads and delivers low-amplitude electrical stimulation. [0003] Since in these conditions the nerves ...
