Problems solved by technology
Since the pulse amplitude is a non-feedback output, even if it is adjusted very accurately at the factory, with the long-term use of the implantable deep brain electrical stimulation system DBS implanted in the human body, it is impossible to ensure that the output pulse amplitude will always remain within the specification. within the required range
Therefore, the prior art has the following defects: (1) The adjustment of the current reference source is time-consuming and labor-intensive; (2) After long-term use, the non-feedback output mode will cause output deviations in the pulse amplitude

Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.
[0016] Such as figure 1 As shown, the implantable electrical nerve stimulation system includes a doctor's programmer 10, a pulse generator 20, and stimulating electrodes (not shown) placed in the patient's body. The stimulating electrodes can be implanted into the patient's brain target tissue, sacral nerve target tissue, spinal cord nerve target tissue, and the like.
[0017] The pulse generator 20 can be placed outside the patient's body, or inside the patient's body. Generally, before being placed in the patient's body, the electrical stimulation test can be performed outside the patient's body. A...

The invention discloses an implantable nerve electrical stimulation control device, an implantable nerve electrical stimulation control system and an implantable nerve electrical stimulation control method. The device comprises a processing module and an output module. The processing module has a first initial pulse amplitude. The output module is used for receiving the first initial pulse amplitude. In an adjustment period, the output module is used for adjusting the first initial pulse amplitude to a first actual pulse amplitude and feeding the first actual pulse amplitude back to the processing module. The processing module is used for calculating a first difference between a target fixed value and the first actual pulse amplitude. When the absolute value of the first difference is not greater than an amplitude threshold, the output module outputs the first actual pulse amplitude. When the absolute value of the first difference is greater than the amplitude threshold, the processing module and the output module adjust the first actual pulse amplitude. Real-time adjustment and accurate output of pulse amplitude are realized through feedback cooperation between the processing module and the output module. On one hand, the accuracy of pulse amplitude is improved, and on the other hand, the production difficulty is reduced.
Description
technical field [0001] The invention relates to an implanted medical system, in particular to an implanted nerve electrical stimulation control device, system and method. Background technique [0002] Implantable medical systems have been more and more widely used in clinical medicine in recent years, usually including implanted nerve electrical stimulation systems (including deep brain electrical stimulation system DBS, implanted cerebral cortex stimulation system CNS, implanted spinal cord stimulation system) Electrical stimulation system to stimulate SCS, implanted sacral nerve electrical stimulation system SNS, implanted vagus nerve electrical stimulation system VNS, etc.), implanted cardiac electrical stimulation system (commonly known as cardiac pacemaker), implanted drug infusion system ( IDDS) etc. Taking the implanted electrical nerve stimulation system as an example, it mainly includes an implanted electrical nerve pulse generator implanted in the body, extension ...
