Intelligent cranial nuclei electric stimulation system

Abstract

The invention relates to an electric stimulus system for an intelligent cranial nerve nuclei mass, which can be used for helping locate the implanted electrode by electrical signals of the feedback electrode peripheral nerve in the process of operation, generates a controllable electrical signal to stimulate a targeted nerve nuclei mass or records, transmits and analyzes the electrical signal of the targeted nerve nuclei mass after the operation so as to automatically adjust the stimulus signal sequence and monitor the change of intracranial pressure. The system is composed of three parts, comprising an implanted part, a radio frequency control part and a power pack in vitro; wherein, the implanted part is composed of six subunits, comprising a stimulus signal generation unit and an information processing unit, a radio frequency communication unit, an intracranial pressure monitoring unit, a neural signal acquisition unit, an electrode and sensor interface and a power supply unit; theradio frequency control unit is mainly composed of five subunits, comprising a radio frequency communication unit, a control unit, an input / output unit, an information processing and analyzing unit and a computer interface; the power pack in vitro mainly consists of two subunits, comprising a coil unit and a high frequency inverter circuit unit.

Description

technical field [0001] The invention relates to a novel medical implantable device for functional electrical stimulation of deep brain nuclei in the field of biomedical engineering. In particular, it is suitable for the positioning of the implanted electrode by feeding back the electrical signal of the peripheral nerve of the electrode during the operation, and generating a controllable electrical signal to stimulate the target nerve nucleus after operation, or to record, transmit and analyze the target nerve The electrical signal of the nuclei automatically adjusts the stimulation signal sequence and monitors the change of intracranial pressure. Background technique [0002] Functional brain diseases are a group of clinical syndromes caused by functional abnormalities of inner groups or nerves in the brain, and most patients are not accompanied by organic diseases. It mainly includes various movement disorders, cranial nerve syndrome, epilepsy, mental illness, nausea and o...

AI Technical Summary

Problems solved by technology

[0005] (1) The deep brain stimulator system has no collection and recording function, and cannot perform precise positioning of nerve nuclei, which affects the curative effect; lacks reliable disease data collection, curative effect evaluation and feedback control system, and cannot be used for in-depth research on brain diseases

[0006] (2) There is no intracranial pressure monitoring device, and it is impossible to monitor the recovery of the brain after surgery

[0007] (3) Powered by disposable batteries, the use time and intensity are limited by the battery power

It is impossible to choose a high-voltage, high-frequency stimulation mode that consumes a lot of power for a long time, which will affect the curative effect; and the stimulation device must be replaced regularly

[0008] (4) The volume of the stimulator (including the battery) is too large, the selection of the surgical site and the positioning during the operation make the patient's surgical wound too large, and the foreign body sensation also causes long-term psychological burden to the patient

[0009] All of these bring unnecessary physical and mental pain and damage to patients, and cause certain economic losses.
