Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0019] Fig. 1 is a system structure block diagram of the present invention. The external deep brain stimulator of the present invention divides the deep brain stimulator into a signal stimulation part inside the body and a signal generation and control part outside the body, and the two parts transmit signals through the signal coupling module coupling coil. As shown in Fig. 2, the signal coupling module is composed of a pair of coils 1, 4 respectively arranged inside the body and outside the body, and an alignment device. The stimulation part inside the body only retains an induction output coil and a pair of stimulation electrodes; the signal generation and control part outside the body includes a pulse drive module, a microcontroller module, a button and display module, a power supply monitoring and charging module, an excitation coil and i...

Abstract

An external deep stimulator for brain and its aligning unit are disclosed. The stimulator has external exciting coil and the induction output coil in human body for the coupling between internal and external signals. The aligning unit has the external permanent magnet close to said exciting coil and two magnetic cores respectively arranged in said exciting coil and induction output coil.

Description

technical field [0001] The invention relates to a deep brain stimulator and belongs to the field of medical equipment. technical background [0002] Deep brain stimulator is commonly known as brain pacemaker, and its English name is Deep Brain Stimulator, or DBS for short. DBS has been widely used in the treatment of movement disorders, and is currently the most promising method for the treatment of Parkinson's Disease (PD). [0003] Parkinson's disease (Parkinson's Disease, PD) is a common middle-aged and elderly nervous system degenerative disease, which usually occurs after the age of 60. and other symptoms. In my country, there are more than 1.7 million patients with Parkinson's disease among the elderly over 55 years old. The prevalence rate is close to that of European and American countries, and the disease shows a trend of younger patients. [0004] Currently, treatments for Parkinson's disease are under constant research. Traditional drug treatment is mainly bas...
