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 fixed 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 sti...

Abstract

The invention discloses an adjusting method of stimulation frequency of a sacral nerve stimulator. The adjusting method comprises steps of setting two groups of stimulation electrodes; setting a stimulation change period, which is a fixed value; sending low frequency pulses to one group of the stimulation electrodes, and sending high frequency pulses to another group of the stimulation electrodes until the stimulation change period is reached; and in the next stimulation change period, exchanging stimulation frequency signals of the two groups of stimulation electrodes. According to the invention, by combining low frequency and high frequency, and electrical nerve stimulation, a bladder is controlled to contract and be fully discharged, and imbalanced contraction of the urethral sphincter is avoided; parts of frequency amplitude values in low frequency are changed, so fatigue to stimulation of nerves and muscles is avoided; only two stimulation points are set and high frequency stimulation and low frequency stimulation are alternatively performed at the two stimulation points, so a problem of the requirement of multiple stimulation points is avoided and difficulty level of an operation 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 ...
