Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0026] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, "connected" can be used for fixing or coupling or communication.

[0027] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations or positional relationships are based on the orientations or positional relationships shown in the drawings, and ar...

Abstract

The invention relates to a deep brain stimulation electrode device which comprises a first electrode, a second electrode, a fixing sleeve and circuit connecting parts, wherein each of first electrodeand the second electrode comprises an electrode implantation part and an electrode fixing part; the electrode implantation part is used for being implanted into a specific target point of the brain; the electrode fixing part is fixedly arranged in the fixing sleeve, and the electrode fixing part and the fixing sleeve are insulated and isolated from each other; the fixing sleeve is arranged so as to be fixed to a position of a skull punching point; the first electrode and the second electrode are fixed to a preset position in the brain through the fixing sleeve; and the first electrode and thesecond electrode introduce electrical stimulation signals through the circuit connecting parts. Through the deep brain stimulation electrode device, electrical stimulation on the target point can be reliably and precisely realized through a dual-channel combined effect; the precise electrical stimulation on a predetermined brain area is achieved; the injury on the brain area is extremely little; the deep brain stimulation electrode device can be used for effectively and safely treating drug addiction; and the influence on free activities of a brain stimulation object by the structure is small.The deep brain stimulation electrode device has the advantages that the implementation of a manufacturing mode is simple; the cost is low; and the mass production is easily realized.

Description

technical field [0001] The invention relates to an implantable medical device, in particular to a deep brain stimulating electrode device. Background technique [0002] Implantable brain electrodes can be applied to brain stimulation, brain signal collection, and neural function reconstruction. Deep brain stimulation (DBS) technology is a new treatment method for the treatment of functional nerves in recent years. It has been widely used in the treatment of drug-refractory advanced Parkinson's disease, dystonia, essential tremor and other movement disorders related diseases. . In addition, DBS technology also has a certain effect on some refractory mental disorders, chronic depression, obesity, drug addiction, etc. Although its mechanism of action is still unclear, when it comes to the treatment of drug addiction, the advantages of DBS technology in terms of micro-injury and adjustable make it possible to replace drug treatment and brain resection surgery. [0003] At pre...
