Problems solved by technology

However, clinical studies have shown that DBS has no significant therapeutic effect on the symptoms of tremor, stiffness, unresponsiveness and posture instability in some Parkinson's patients
For other patients, DBS may cause side effects such as cognitive decline, depression, language dysfunction, and decreased balance ability, which may cause symptoms such as memory loss, dysphonia, and easy falls.
Moreover, once a patient adapts to a fixed frequency of stimulation, the therapeutic effect declines over time
[0003] At present, some DBS try to solve the problem of ineffectiveness by increasing the stimulation frequency, but continuous high-frequency stimulation also has many disadvantages
First, increasing stimulation frequency also increases the risk of side effects
Secondly, continuous high-frequency stimulation increases power consumption and shortens the service life of equipment
Finally, continuous high-frequency stimulation still uses a single frequency, which cannot solve the problem that the therapeutic effect is reduced due to patient adaptation

Abstract

The invention provides an implantable nerve stimulation device. The implantable nerve stimulator comprises a random number generator which is used for generating random numbers in sequence. The adjacent random numbers are not equal, and the random numbers are used for indicating the frequency of pulses. The implantable nerve stimulator further comprises a pulse output circuit which is used for sequentially outputting stimulation pulses with random frequencies according to the random numbers.

Description

technical field [0001] The invention relates to the field of implantable medical equipment, in particular to implantable nerve stimulation equipment. Background technique [0002] Traditional implantable deep brain stimulators (DBS) mostly use a single fixed-frequency pulse stimulation. However, clinical studies have shown that DBS has no significant therapeutic effect on the symptoms of tremor, stiffness, unresponsiveness and posture instability in some Parkinson's patients. For other patients, DBS may cause side effects such as cognitive decline, depression, language dysfunction, and decreased balance ability, causing patients to suffer from symptoms such as memory loss, dysphonia, and easy falls. Moreover, once a patient adapts to a fixed frequency of stimulation, the therapeutic effect declines over time. [0003] At present, some DBS attempts to solve the problem of ineffectiveness by increasing the stimulation frequency, but continuous high-frequency stimulation also...
