背景技术
微丝电极是一种微型可植入大脑,并提取脑信号的电极,在脑神经研究领域有着至关重要的作用,广泛用于高校相关研究,传统的微丝电极电极丝的长度是固定的,不能单独控制每根电极丝的刺入深度,而微丝电极的电极丝通常采用电极丝阵列,在植入到一定深度时,往往有个别电极丝因为电极尖端的位置不合适而无法采集到良好的电信号,如果整体调整电极丝的植入深度,对其他电极丝的位置又会产生影响。
发明内容
为了解决上述问题,本发明提供了一种新型气压式控制的微丝电极。技术方案如下:
包括智能气压阀门;
进出气装置,包括进气管、出气管,所述进出气装置安装于所述智能气压阀门;
电极壳体;
气塞,安装于所述电极壳体内部,配置成所述气塞可在所述电极壳体的内部滑动;
电极丝,与所述气塞固定连接;
粘贴片,安装于所述电极壳体外部,配置成可粘贴于大脑表皮;
每根所述电极丝依次穿过所述电极壳体和所述粘贴片相应的孔洞,使多根所述电极丝形成电极丝阵列。
优选的,所述进出气装置还包括通气管,所述通气管安装于所述智能气压阀门和所述电极壳体之间。
优选的,所述微丝电极还包括测距装置,设置于所述气塞上,配置成可测量所述电极丝的尖端相对所述电极壳体的移动距离。
本发明所取得的有益效果是:能够利用气压控制每根电极丝刺入大脑深度,并且电极可以贴附在大脑表皮。
