Problems solved by technology

The biggest disadvantage of this product is: the power supply battery of the DBS implanted in the human body cannot supplement the electric energy from outside the body, it can only be used once, and its life span is 3-5 years
It not only increases the patient's pain and surgical risk, but also increases its economic burden

Embodiment

[0040] The power converter 1 and the power coupling component 9 in the power module 10 form a primary side and a secondary side of energy conversion. The primary side uses high-frequency switching to generate pulse signals with a frequency of 10-20kHz. After passing through the L and C energy storage elements, resonance energy coupling is generated, and an induced electromagnetic field is generated in the secondary side inductance to provide electrical energy for the stimulation pulse generator. The switch can be MOSFET, SRC, etc., and the energy storage element can be rechargeable battery or super capacitor. Selection of materials: the shell material can be titanium alloy, etc.

[0041] The low-power solution for the stimulus pulse generator is as follows:

[0042] 1. As the core microprocessor of the stimulation pulse generator, the MSP430 series of ultra-low power consumption is selected, with its own A / D converter, and the ultra-low power consumption D / A converter MAX5512...

Abstract

The invention discloses a rechargeable stimulator for deep parts of brain, which comprises an electrical energy transforming apparatus, an exterior control monitoring apparatus outside human body and a stimulation impulse generator implanted into hypodermal of human body, wherein the electric energy transforming apparatus is used to generate high-frequency resonant electromagnetic field, the high-frequency resonant electromagnetic field penetrates human body skin and conveys electrical energy to the stimulation impulse generator, which includes an electric energy coupling module for receiving the high-frequency resonant electromagnetic field and transform it into electric energy, wherein the power supply regulating module provide electrical source to the stimulation pulse generator.

Description

technical field [0001] The invention relates to a percutaneously charged implantable deep brain stimulator. Background technique [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 is one of the common diseases of the nervous system in middle-aged and elderly people. In my country, it is estimated that there are currently about 1.1 million to 1.5 million patients. Clinically adopted treatment methods include drug therapy and surgical treatment. However, people have gradually found that the curative effect of the drug decreases after long-term use, and serious side effects that are difficult to solve by medical treatment appear. The current surgical treatment of PD is usually to ...
