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 suffering of patients, but also increases their economic burden
In addition, DBS is installed under the neck and inside the scapula of the patient through procedures, which increases the pain and complexity of the operation for the patient.

Embodiment Construction

[0017] The external deep brain stimulator of the present invention will be described in detail below in combination with specific embodiments.

[0018] Such as figure 1 As shown, the external deep brain stimulator of the present invention includes a built-in induction coil 4 and stimulating electrodes 5 implanted under the skin of the human body, and an external controller 1 located outside the human body. The external controller 1 is composed of a power converter, a microprocessor 13 , a keyboard 12 connected to the external microprocessor 13 , a display 14 and a intermittent oscillator 11 . The power converter is composed of a power management circuit 8, a resonant circuit 9 and an external induction coil 2 connected in sequence. The keyboard 12 and the display 14 are used to set the amplitude, frequency and width of the stimulation pulse. Under the control of the microprocessor 13, the resonant circuit 9 is controlled by the intermittent oscillator 11 to generate the stimu...

Abstract

An external stimulator for the deep brain is composed of the internal induction coil and stimulating electrode, which are transplanted in human body, and the external controller for setting up the amplitude, frequency and width of stimulating pulses and composed of microprocessor, keyboard, display, interrupted oscillator, and the electric energy converter resisting of rectifying-filter circuit, resonance loop and external induction coil.

Description

technical field [0001] The invention relates to an external deep brain stimulator, which is used for the treatment of Parkinson's disease, torsion spasm, spastic torticollis, chorea, obsessive-compulsive disorder, epilepsy and other diseases. 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, ...
