Description
Technical field
This utility model belongs to the electrophysiological technique field, refers more particularly to a kind of deep brain stimulation electrode.
Background technology
In the Neural Technology field, deep brain stimulation (deep brain stimulation, DBS) device is also referred to as brain pacemaker, the specific region implant electrode of brain, continuously transmit boost pulse to the deep-brain specific region to reach therapeutic purposes.The consists lithium battery power supply, accept the controller adjusting of skin outside, can adjust pulsewidth, frequency and the intensity of stimulation, to obtain best therapeutic effect, probe is that the coil that scribbles insulant connects four electrodes formations, uses the target region that stereospecific technology is placed on brain.Five sixties of last century, DBS is used for the treatment of intractable pain the earliest, after be used for the treatment of again epilepsy, modern DBS starts from 1987, France professor Benabid is first with trembling that the alternative Thalamotomy operative treatment parkinson disease of DBS cause, DBS treatment Parkinson's disease therapy has been passed through in Canada, Europe, Australia in 1998,1997, drugs approved by FDA DBS treatment essential tremor and Parkinson's tremor, went through to treat parkinson disease in 2002, go through to treat myodystonia in 2003, went through to treat obsession in 2009.Over past ten years, DBS has developed into one to the effective Therapeutic Method of multiple sacred disease, and the scope of DBS treatment sacred disease is in continuous increase, and the mechanism for the treatment of these diseases for DBS has also had further investigation progressively.The characteristics such as DBS receives much concern because having the clear and definite characteristic of target spot, and it has alternative, controllability, reversibility, Wicresoft's wound is little and safety is high.
Over past ten years, DBS is flourish abroad as the method for the multiple sacred disease of a kind of effective treatment.It is evident in efficacy that let it be to the greatest extent, but the definite therapy apparatus system of at present relevant DBS, the suitableeest target spot is still unclear.And animal model is to the mechanism of action of illustrating DBS with seek best target and have important effect, but the research of animal model so far still far lags behind the clinical practice of DBS.At present the DBS zooscopy is mainly on primates and rat, and wherein rat has that reproductive capacity by force, is easily raised and the characteristics such as body size is suitable, is a kind of laboratory animal commonly used when carrying out the research such as physiology, behavioristics, hereditism, pharmacology.The DBS therapeutic effect depends on the correct position that electrode acts on the corresponding target spot in brain district, but because rat brain district area is less, therefore having relatively high expectations to electrode: both required electrode to be convenient in the location of the corresponding target position in brain district, and satisfied again the electrode active area simultaneously little and do not affect other core group function.At home, most of electrodes often adopt concentric design, mainly from import or the customization of domestic minority producer, expensive, recovery utilization rate is low, and general zoopery requires sample size larger, so fancy price has limited this class electrode application at home greatly.Therefore, develop a kind of easy and simple to handlely, material requested is simple and easy to, low cost of manufacture, and the electrode that can be widely used not only can be saved a large amount of scientific research funds, and also have great importance for the research work of DBS mechanism of action.
