Abstract

The invention discloses an active magnetic stimulation nerve modulation device. The modulation device comprises an intracranial magnetic source module and a magnetic stimulation module; the intracranial magnetic source module uses intracranial mature lacuna such as artery, vein and cerebrospinal fluid as an implantation channel; the intracranial magnetic source module comprises a magnetic support, and the magnetic support is provided with a magnetic piece; the magnetic stimulation module comprises a fixing mechanism and a magnetic field generation module; the magnetic field generation module generates a magnetic field to be matched with the magnetic support on the intracranial magnetic source module to modulate nerves; and the magnetic piece comprises a magnetic material, and the magnetic support is covered with the magnetic material. According to the modulation device, accurate delivery is performed through an interventional operation, the targeting property of treatment is increased, and the focusing property of magnetic stimulation is increased by increasing an intracranial active magnetic field, arranging a plurality of endogenous magnetic fields and aiming at different target spots; and due to the existence of the endogenous magnetic fields, the stimulation time is prolonged, continuous stimulation can be performed, active magnetic stimulation makes up for the deficiency of the existing TMS, and improves the curative effect of neurological disease treatment.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an active magnetic stimulation nerve modulation device. Background technique [0002] As a non-invasive and non-invasive neuromodulation technology, transcranial magnetic stimulation has important applications in the exploration of the causes of mental disorders and the treatment of mental diseases. The performance of the TMS system directly affects the neuromodulation effect, but there is still an urgent contradiction to be resolved between the performance level of the existing TMS system and the performance requirements of clinical applications and scientific research. In view of the problems of insufficient intracranial induced electric field stimulation intensity, low focusing, and poor targeting that are generated by traditional TMS coils, in addition, the existing magnetic stimulation mechanism also has the problems of large required magnetic field intensity, short workin...
