Problems solved by technology

[0004] The pulse generator is implanted in the chest, and it is necessary to create a long subcutaneous tunnel to connect the extension wire and the electrode, and the operation is relatively complicated
Moreover, the extension wire passes through the neck from the chest and connects to the electrode under the skin of the head. The movement of the neck can easily cause the extension wire to be stressed, which will cause a series of problems such as connection failure, extension wire or electrode breakage, etc.

Embodiment Construction

[0032] A traditional deep brain stimulation system is mainly composed of a pulse generator 1, an extension wire 2 and an electrode 3, such as figure 1 As shown, the pulse generator 1 is implanted under the skin of the chest and connected to the extension lead 2, which passes from the subcutaneous of the chest to the subcutaneous of the neck, and is connected to the electrode 3 under the skin of the head. When the neck moves, it is easy to pull the extension cord 2, so that the extension cord itself and the joint between the extension cord 2 and the electrode 3 are stressed. The implantation of the extension lead 2 requires the creation of a subcutaneous tunnel between the chest and the head, which is relatively traumatic.

[0033] like figure 2 As shown, the deep brain electrical stimulation system of the present invention is all implanted in the head, no longer needs to extend the wire, the pulse generator 1 is directly connected to the electrode 3, the electrode is fixed b...

Abstract

The invention discloses a deep brain electric stimulation system implanted in the head, and belongs to the technical field of implanting type medical instruments. Due to the fact thats the whole system is implanted in the head of the human body and an electrode is directly connected with a pulse generator, operation complexity can be reduced, stress of a connection port and the electrode can be avoided, and reliability of the system is enhanced.

Description

technical field [0001] The invention relates to a nerve electric pulse stimulation system which is completely implanted in the head, and belongs to the technical field of implantable medical instruments. Background technique [0002] For some types of neurological diseases, such as Parkinson's disease, epilepsy, torsion spasm, spastic torticollis, chorea, idiopathic vertigo, clinically commonly used drug therapy and surgical treatment, but side effects and complications are important disadvantages. Deep brain stimulation therapy performs chronic electrical pulse stimulation by stimulating different functional nuclei in the deep brain, such as stimulating the subthalamic nucleus and globus pallidum for Parkinson's disease. Treatment is an ideal treatment method, and it is used more and more widely. [0003] The implanted part of the existing deep brain electrical stimulation system currently on the market is usually composed of a pulse generator, extension wires and electro...
