Abstract

The invention discloses an adaptive control module, a control method thereof and an interpolated nerve stimulation system. The control module cooperated with a stimulation part comprises a stimulationunit, an neutralization unit and a control unit; the stimulation unit provides negative stimulation for the stimulation part and generates a negative charge variance; the neutralization unit providespositive stimulation for the stimulation part and generates a positive charge variance; and in a predetermined stimulation period, the control unit controls that output of the neutralization unit and / or the stimulation unit so that the absolute value of the negative charge variance equals that of the positive charge variance. The module, system and method have the advantages that (1) the introduced control unit can control output of the the neutralization unit and / or the stimulation unit to realize electric neutralized balance; (2) electric neutralized balance can be kept for any stimulationwaveform; and (3) electric neutralized balance is also suitable for clinically constant voltage, constant current or variable frequency stimulation mode.

Description

technical field [0001] The invention relates to the field of implantable medical treatment, in particular to an adaptive control module, an implanted nerve stimulation system and a control method. Background technique [0002] Implantable medical systems have been more and more widely used in clinical medicine in recent years, usually including implantable neurostimulation systems (including deep brain stimulation system DBS, implantable cerebral cortex stimulation system CNS, implantable spinal cord stimulation System stimulation SCS, implantable sacral nerve stimulation system SNS, implantable vagus nerve stimulation system VNS, etc.), implantable cardiac stimulation system (commonly known as cardiac pacemaker), implantable drug infusion system (IDDS), etc. [0003] Implantable neurostimulation systems such as figure 1 As shown, the following components are generally included: several stimulating electrode contacts 30 (here, taking the left brain electrode contacts and th...
