Description

用于植入电极丝的系统及其运行方法 技术领域
本公开涉及用于植入电极丝的系统、用于向目标物植入生物电极的系统、用于向目标物植入电极丝的系统以及用于运行根据本公开的系统的方法。
背景技术
柔性神经电极作为脑机接口领域的重要工具目前正在被国内外科研及商业机构开发并逐渐完善中。柔性神经电极相比于传统硬质神经电极最大的优势在于其优良的机械相容性,不易在脑组织中形成瘢痕。但也由于电极丝本身机械强度低、易变形,在植入脑组织过程中容易断裂,不容易穿过脑膜进入到组织中。因此,目前植入柔性神经电极的工具和方式是一个技术难点。
目前现存的植入方案中,主要分为两大类:手动植入与机器辅助植入。手动植入是以纯人工操作手段进行电极丝的植入,通常第一步是要提前准备好所有要植入的电极丝以及对应每根电极丝的引导针,需要将电极丝提前以粘连或者套环的方式固定在每根引导针上,然后找到要植入的脑组织区域,将一排引导针带电极丝同时植入到目标区域。此方法存在许多问题包括:1)准备时间长;2)因为电极整体尺寸限制,一次只能植入有限数量的一排电极丝,如果需要植入超过一排电极丝的数量则需要准备多个引导针加电极丝的组合,耗费大量准备时间和资源;3)由于每次需要将一排电极丝同时植入,无法自由选择植入的位点;4)手动植入还存在植入速度不够,可能会导致引导针无法穿过硬脑膜将电极丝植入。
综上所述,手动植入的方式存在许多问题,鉴于这些问题,由机器人辅助植入的方式是目前最具希望解决方案。机器人具有相较于人更精确的工作完成能力以及完成重复性工作的一致性能力。目前仍然存在诸多问题,比如植入头安装在一个三轴的移动平台上,这样会导致植入头无法以不同的角度进行植入,只能在XYZ轴上做直线运动,由于人脑表面并非平面,这样会导致电极丝无法预计植入的角度。另外一个问题是植入头部的针加夹子的形式容易导致电极丝断裂,除非电极丝的硬度够大,但硬度大又会导致脑组织的损伤加大,所以此结构存在风险。

如图所示,根据本公开的用于植入电极丝1的系统包括植入装置100。植入装置100可以包括植入针110、植入进给机构120和植入执行机构130。植入针110可以构造成用于将以其针头部分111接合电极丝1的自由端部,以便带动电极丝1运动。植入进给机构120可以构造成用于使植入针110沿植入装置100的纵向方向移动。植入执行机构130可以构造成用于驱动植入针110以将植入针110的针头部分111扎入脑部中。此外,用于植入电极丝1的系统还包括植入运动机构,该植入运动机构与植入装置100相配设。植入运动机构可以构造成用于使植入装置100能够从不同角度在不 同的朝向下进行电极丝1的植入。换言之,根据本公开的用于向目标物植入生物电极的系统包括执行机构,该执行机构构造成驱动与生物电极接合的引导装置运动,以使引导装置连同生物电极进入目标物。该引导装置可以构造为植入针110。该目标物可以包括脑。目标物可以包括非平坦的表面。例如,目标物可以脑部表面。该生物电极可以包括柔性电极丝1(或称为丝状柔性电极)。用于向目标物植入生物电极的系统还包括位置调整机构以及朝向调整机构,该位置调整机构构造成调整执行机构的位置,以使引导装置接近目标物的目标植入区域,该朝向调整机构构造成调整执行机构的朝向,以使引导装置能够在目标植入区域处以相对于目标植入区域表面的特定角度进入目标物。
如图1至图3所示,植入运动机构包括可在空间中自由运动的机械臂210。该机械臂210可以为常见的多轴机械臂210。通过该机械臂210可以实现6自由度或7自由度。如图4所示,植入运动机构还可以包括弧状导轨220,植入装置100可以在该弧状导轨220上滑移。在该弧状导轨220上可以开有未示出的滑槽。在植入装置100的背离植入针110的端部上设有与该滑槽相配合的滑块,通过该滑块可使得植入装置100在弧状导轨220上沿着弧状轨道滑移。弧状导轨220能够围绕法向于弧状导轨220的弧线并且延伸穿过弧状导轨220中心的转动轴线转动。由此,通过使弧状导轨220的转动与植入装置100在弧状导轨220上的滑移相组合,植入装置100基本上可以在一个半球形的区域内以任意朝向定向。在此,可以设置有机械臂210和弧状导轨220中的至少一个。在图1至图3中,示出仅设置有机械臂210的实施例。本领域技术人员应理解,在其他实施例中,也可以仅设置有弧状导轨220,或者同时设置有机械臂210和弧状导轨220。在同时设置有机械臂210和弧状导轨220时,植入装置100能够经由弧状导轨220与机械臂210连接。通过直接将植入装置100布置在弧状导轨220上,可以使产生角度变化运动的装置从误差链角度看更靠近执行终端、即植入针110,从而可以有效地控制角度变化误差。
位置调整机构的至少部分可以被实现为机械臂210。位置调整机构可以包括位置粗调模块和位置精调模块。朝向调整机构和位置粗调模块的至少部分可以被实现为机械臂210。由此,通过机械臂210一方面可以实现安置在机械臂210上的整个组件和属于该组件的引导装置沿各个方向的平移或者说位置粗调,另一方面可以实现引导装置朝向的调节。位置精调模块可以包括微动电机。微动电机可以布置在引导装置或者说植入针110的靠近目标物的端部处。例如,植入针110的针头部分111可以配备有 微动电机,微动电机能够使所述针头部分111在植入装置100的横向方向上运动。由此,在通过机械臂210进行位置粗调和朝向调节之后,可以根据目标物的具体情况通过引导装置上的微动电机对引导装置的位置进行精细调节,以位置精确地进行引导和植入操作。为了实现朝向的调节,朝向调整机构还可以包括弧状导轨220,执行机构的远离引导装置的第一端被安装到弧状导轨220,以便朝向调整机构调整执行机构的朝向。弧状导轨220如上所述可以围绕其转动轴线转动。朝向调整机构、如弧状导轨220可以设置于位置调整机构上,以使得位置调整机构通过调整朝向调整机构的位置来调整执行机构的位置。在图1至图3所示的实施例中,执行机构固定布置在背板230上,该背板230安置在机械臂210上。用于植入电极丝1的系统包括电极丝1支架,电极丝1支架能够接纳电极丝1,电极丝1支架布置在承载框架240上,承载框架240固定在背板230上。电极丝1支架可运动地布置在承载框架240上。电极丝1支架通过平面运动机构连接到承载框架240,平面运动机构构造为沿基本上平行于背板230的方向和基本上垂直于背板230的方向两者运动。换言之,用于固定电极的电极固定装置300可以布置在横向调整模块250上,使得该电极固定装置300可以沿横向方向移动,而横向调整模块250可以在纵向调整模块上移动,由此电极固定装置300总体上可以沿横向和纵向方向移动。在这种情况下,执行机构在安置在机械臂210上的框架结构中是固定的,而用于固定电极的电极固定装置300是可移动的,以调节执行机构与电极之间的相对位置。在其他实施例中,位置调整机构还可以包括纵向调整模块和横向调整模块250,其中,纵向调整模块构造成沿执行机构的纵向调整执行机构的位置,以使引导装置沿纵向接近目标植入区域;以及横向调整模块250构造成在与纵向垂直的平面上调整执行机构的位置,以使引导装置沿横向接近目标植入区域。执行机构可以布置纵向调整模块上,纵向调整模块可以在横向调整模块250上移动,或者执行机构可以布置在横向调整模块250,横向调整模块250可以在纵向调整模块上移动。在这种情况下,执行机构在框架结构中是可移动的,而用于固定电极的电极固定装置300可以是固定的。通过将执行机构布置在纵向调整模块或横向调整模块250上,可以为弧状导轨220的安装提供足够的安装空间。当然,在执行机构在框架结构上固定设置时,为了给弧状导轨220的安装提供安装空间,可以垂直于背板230伸出例如一个固定件,该固定件弧状导轨220可以可转动地安装在该固定件上。横向调整模块250和/或纵向调整模块可以构造为电机、如步进电机。
在图1至图3中所示的实施例中,植入装置100的针头部分111设置在滑板上, 该滑板可以通过植入执行机构130在滑轨上快速移动,以执行植入操作。在图5至图7中示出植入装置100的另一种实施例。在该另一种实施例中,植入装置100还可以包括用于布置植入执行机构130的第一植入承载件133,第一植入承载件133能够通过植入进给机构120进行直线运动。植入进给机构120可以包括第一引导块121和第一直线导轨122。第一引导块121能够在第一直线导轨122上进行直线运动。第一引导块121能够经由传动机构在第一直线导轨122上进行直线运动,所述传动机构能够将旋转运动转变为第一引导块121的直线运动。该植入进给机构120可以构造为步进电机。该传动机构可以构造为螺杆传动机构123。第一植入承载件133与植入进给机构120的第一引导块121一体式构造。第一植入承载件133也可以可拆卸地布置在植入进给机构120的第一引导块121上。第一植入承载件133例如可以螺纹连接在植入进给机构120的第一引导块121上。植入装置100还可以包括用于固定植入针110的第二植入承载件134,所述植入执行机构130能够驱动第二植入承载件134进行直线运动,从而将植入针110的针头部分111扎入脑部中。植入执行机构130可以构造为高速驱动电机,通过磁力驱动第二植入承载件134执行高速植入操作。第二植入承载件134配设有第二引导块131和第二直线导轨132,第二引导块131能够在第二直线导轨132上进行直线运动,第二植入承载件134布置在第二引导块131上,从而第二植入承载件134在被植入执行机构130驱动时以被引导的方式经由第二引导块131在第二直线导轨132上进行直线运动。植入执行机构130可以构造为电磁执行机构,所述电磁执行机构能够驱动第二植入承载件134连同第二引导块131在第二直线导轨132上运动限定的行程,从而使针头部分111运动限定的行程。植入执行机构130也可以构造为气动执行机构,在第二直线导轨132上设置有止挡部,所述气动执行机构能够驱动第二植入承载件134连同第二引导块131在第二直线导轨132上运动,直到第二引导块131止挡在止挡部上,从而使针头部分111运动限定的行程。构造为步进电机的植入进给机构120及传动螺杆可以将整个植入执行机构130向下移动至制定高度,然后由植入执行机构130驱动植入针110进行电极植入。植入完成之后再由植入进给机构120将植入针110向上送回初始高度。
由图7可以清楚看出,第二植入承载件134可以包括植入针固定块135,植入针110能够可拆卸地固定在植入针固定块135上。植入针110可以两件式地构造,植入针110可以包括针管部分112和针头部分111,针头部分111可以固定在针管部分112的端部上或嵌入到针管部分112中。植入针110能够经由转接头固定在植入针固定块 135上,其中,针管部分112的背离针头部分111的端部可以经由转接头固定在植入针固定块135上,固定方式可以采用螺纹固定以及环氧树脂固定方法。植入针110可以材料锁合地连接在转接头上,其中,转接头与针管部分112可以例如通过粘接、焊接等进行连接。
为了将针头部分111扎入脑部,植入执行机构130能够使针头部分111以介于0.5m/s至5m/s之间或介于0.01m/s至10m/s之间的速度扎入脑部。在一个示例中,进行脑部神经植入之前,需要将植入目标物进行麻醉;备皮剪开头皮以暴露颅骨之后,在目标植入区域打开颅骨,形成一个脑窗;然后揭掉脑窗范围内的硬脑膜,将脑表面暴露出来。植入执行机构130可以驱动针头部分111以大于等于1m/s的速度朝向目标植入区域运动,以便针头部分111可以穿刺软脑膜进入目标植入区域。在一个示例中,可以不揭掉脑窗范围内的硬脑膜,替代地,在植入的目标位点处进行定点硬脑膜开孔,例如可以使用脉冲电场消融(PFA)、热消融、微波消融、光波消融、射频消融、激光消融、冷冻消融等消融手段作为开孔技术。其中,较佳地,使用脉冲电场消融的方式。因为与其他消融方式相比,脉冲电场消融是非接触式、非热能、特异性的消融方式。然后,植入执行机构130可以驱动针头部分111朝向开孔的植入位点处运动,以便进行植入。运动的速度可以等于或者较佳地略高于揭掉硬脑膜的情况下针头部分111的运动速度。在一个示例中,可以不采用上述两种方式,替代地,将植入目标物的颅骨的外板(颅盖骨骨密质的部分)磨去,例如用外科颅钻磨去目标植入区域的颅骨的外板,但不暴露脑表面。植入执行机构130可以驱动针头部分111以大于等于3m/s的速度朝向目标植入区域运动,以便针头部分111可以穿刺磨薄的颅骨进入目标植入区域。
在进行植入时,需要控制植入深度,涉及植入深度的两个参量是植入初始位置(指沿植入装置100的z轴的位置)和植入行程。植入行程如上所述通过电磁执行机构或气动执行机构本身所产生的限定的行程来实现。植入初始位置可以体现为针头部分111的尖端与脑表面之间的距离。为确定该距离,根据本公开实施例的系统可以包括脑表面探测装置,脑表面探测装置能够检测到可导电的针头部分111接触脑部表面。脑表面探测装置可以包括探测电路,针头部分111连接在探测电路上,被植入生物体的另一个部位接入电路,其中,在该电路上连接有电压测量装置,在针头部分111接触脑部表面时,电路接通,电压测量装置测量到电压,以指示针头部分111接触到脑部表面。在针头部分111接触到脑部表面之后,控制植入进给机构120以使植入针110 回撤预定距离,从而使得植入针110的针头部分111的尖端位于距离脑表面的预定距离处,即位于初始位置处。该预定距离d可以根据针头部分111的尖端需要进入目标植入区域的深度D和电磁/气动执行机构具有的限定的行程S来确定,即d=S-D。针头部分111的尖端需要进入目标植入区域的深度D可以根据电极需要被植入的深度、以及电极接合到针头部分111的位置来确定。
换言之,根据本公开实施例的用于向目标物植入电极丝1的系统包括植入子系统,植入子系统包括:执行机构,构造成驱动与电极丝1接合的引导装置沿执行机构的纵向以第一速度朝靠近目标物的方向运动,以使引导装置连同电极丝1进入目标物;以及纵向位置调整机构,构造成沿纵向以第二速度调整执行机构的位置,以使引导装置沿纵向接近目标物的目标植入区域,其中,所述第一速度大于第二速度。执行机构还构造成驱动进入目标物的引导装置沿纵向以第三速度朝远离目标物的方向回撤,以使引导装置退出目标物。在此,第一速度和第三速度均介于0.5m/s至5m/s之间,或介于0.01m/s至10m/s之间。如上所述,可以根据需要设置不同的速度,以实现软脑膜穿刺、硬脑膜穿刺以及薄颅骨穿刺。执行机构驱动引导装置回撤的加速度介于25m/s 2至35m/s 2之间,引导装置以较大的加速度回撤,有利于电极与引导装置脱离,尽量避免引导装置撤出目标植入区域时带出电极。执行机构可以包括电磁致动模块、高速电机致动模块、或气动模块。执行机构还构造成驱动引导装置沿纵向运动特定的行程,所述植入子系统还包括:植入深度控制模块,构造成控制纵向位置调整机构以使引导装置的尖端位于距离目标植入区域的表面的预定距离处,再控制执行机构驱动引导装置运动。植入深度控制模块还构造成控制纵向位置调整机构以使引导装置接近目标植入区域,直至引导装置的尖端接触到目标植入区域的表面停止,然后控制纵向位置调整机构以使引导装置回撤预定距离,从而使得引导装置的尖端位于距离目标植入区域的表面的预定距离处。植入深度控制模块通过在引导装置的尖端接触到目标植入区域的表面即被接通的探测电路,来探测引导装置的尖端接触到目标植入区域的表面。
此外,植入子系统还包括:朝向调整机构,构造成调整执行机构的朝向,以使引导装置能够在目标物的目标植入区域处以相对于目标植入区域表面的特定角度进入目标物。如上文所述类似地,植入子系统还包括:横向位置调整机构,构造成在与纵向垂直的平面上调整执行机构的位置,以使引导装置对准目标植入区域。植入子系统还可以包括电极固定装置300,构造为在其靠近目标物的表面上可分离地固定所述电极丝1。在该实施例中,引导装置是可移动的,而电机电极固定装置300可以是固定 不动的。在其他实施例中,电极固定装置300也可以配设有横向位置调整机构,使得电极固定装置300在与纵向垂直的平面上调整位置,而执行机构的位置可以是固定不动的。横向位置调整机构可以具有小于4μm的调整精度。上述两种实施例都可以实现执行机构与电极固定装置300之间的相对位置的变化。当然,在其他实施例中,电极固定装置300和执行机构也可以都构造为可移动的。
在此参考描述根据本公开实施例的用于运行根据本公开的系统的方法中的电极丝引导步骤的图8A至图8C,可看出,电极固定装置300包括支撑板310,支撑板310可以在其靠近(或朝向)目标物的表面上可分离地固定电极基板320。电极丝1可以被粘附于电极基板320上,从而被固定在支撑板310上。由于电极丝1具有较大的柔性并且具有较小的机械强度,不便于固定在支撑板310上,因此可以借助于硬度高于电极丝1的电极基板320。电极基板320可以由高分子聚合物制成,并与电极丝1共同被制造,以为被植入目标物之前的电极丝1提供限位与支撑。在实施中,多个电极丝1通常被批量地共同形成,这样的多个电极丝1可以被形成为并排粘附于电极基板320上。根据植入的需要,可以将这多个电极丝1中的一个电极丝1植入目标物,也可以将这多个电极丝1中的多个电极丝1依次植入目标物。
植入子系统还可以包括:电极位置调整机构,构造成沿与纵向垂直的平面调整电极固定装置300的位置,以使引导装置沿纵向从电极固定装置300的远离目标物的第一侧向电极固定装置300的靠近目标物的第二侧运动的过程中,能够与固定在电极固定装置300上的电极丝1相接合。在电极丝1的自由端部上可以设置有环,例如圆环、椭圆环、半圆环、矩形环等,植入针110或引导装置的尖端能够穿过环以接合电极丝1的自由端部。
在使植入针110或者说引导装置与电极丝1相接合时,需要观察定位电极丝1前端的接合部位和植入针110的尖端。如图1至图3所示,为此根据本公开实施例的用于植入电极丝1的系统还可以包括:第一光源410,所述第一光源410用于提供适于观察植入针110和电极丝1的自由端部的第一光;第二光源420,所述第二光源420用于提供适于观察脑部表面的第二光;第一相机430,所述第一相机430构造成在第一光的辅助下获取针头部分111和电极丝1的自由端部的第一图像;第二相机440,所述第二相机440构造成在第一光的辅助下获取针头部分111和电极丝1的自由端部的第二图像,其中,第一相机430的光路和第二相机440的光路彼此成角度;脑部表面相机450,所述脑部表面相机450构造成在第二光的辅助下获取脑部表面的第三图 像;以及处理装置,所述处理装置构造成基于第一图像和第二图像识别针头部分111与电极丝1的自由端部相对位置,以及基于第三图像识别脑部表面的可植入区域。第一光包括白光、蓝光、红光、红外光和近紫外光中的一个或多个,和/或,所述第二光包括绿光。第一相机430以及脑部表面相机450可以布置在背板230上。第二相机440可以布置在承载框架240的与背板230相对置并基本上平行于背板230的第一承载区段上。第一相机430和/或所述第二相机440构造成位置可调整的,以便调整其位置使得针头部分111和电极丝1的自由端部以可被观察的清晰度呈现在其视野中。第一相机430和第二相机440可以布置成,使得第一相机430的光路和第二相机440的光路在电极丝1的自由端部处汇聚。如图9所示,假定观察目标(电极丝1末端)位于图中坐标系原点O。第一相机430与第二相机440需要同时观察目标。第一相机430的光路与第二相机440的光路显示两个相机的观察方向。第一相机430及其镜头可以布置在XZ平面上,第二相机440及其镜头布置在YZ平面上。第一相机430的光路与X轴的初始设定夹角可以为45°,且可根据使用者要求进行调整。第二相机440的光路与Y轴的初始设定夹角同样可以为45°,且可根据使用者要求进行调整。
换言之,根据本公开实施例的用于向目标物植入电极丝1的系统还可以包括观察子系统,所述观察子系统包括:视觉模块400,构造成获取引导装置的用于接合电极丝1的端部、以及被固定在电极固定装置300上的电极丝1的用于接合引导装置的端部的第一图像;以及运算控制模块,构造成基于第一图像识别引导装置的端部与电极丝1的端部的相对位置,并基于识别结果控制电极位置调整机构调整电极固定装置300的位置和/或控制横向位置调整机构调整执行机构的位置,以使引导装置沿纵向从电极固定装置300的第一侧向第二侧运动的过程中,引导装置的端部能够与固定在电极固定装置300上的电极丝1的端部相接合。视觉模块400还构造成获取目标物的第二图像,运算控制模块还构造成基于第二图像识别目标物的目标植入区域,并基于识别结果控制横向位置调整机构调整执行机构的位置,以使引导装置对准目标植入区域。
如图1至图3所示,用于植入电极丝1的系统还可以包括喷雾装置500,喷雾装置500构造为保持脑部表面和/或周围环境湿润、和/或使电极丝1贴附于植入针110。换言之,用于向目标物植入电极丝1的系统还可以包括辅助子系统,所述辅助子系统包括:第一喷雾装置,被布置在目标物附近,构造成提供喷雾以保持目标物表面和/或周围环境湿润;和/或第二喷雾装置,被布置在引导装置与电极丝1的接合处附近,构造成对电极丝1施加喷雾,以使得电极丝1贴附于引导装置。
图8A至图8E是根据本公开实施例的用于运行根据本公开的系统的方法中的电极丝引导以及喷雾步骤的示意图。下面参照8A至图8C说明用于运行根据本公开实施例的系统的方法,其中,所述方法包括以下步骤:将电极丝1布置在电极丝1支架上;由处理装置基于所述第一图像和所述第二图像识别电极丝1的自由端部以及植入针110的针头部分111之间的相对位置,并基于相对位置控制植入装置100和/或电极丝1支架运动,以使得植入针110的针头部分111沿纵向方向对准电极丝1的自由端部;通过植入进给机构120使植入针110沿植入装置100的纵向方向运动以接合到电极丝1的自由端部,并使电极丝1脱离电极丝1支架;由处理装置基于所述第三图像识别脑部的可植入区域,并在可植入区域中确定植入的目标位置;由处理装置控制植入装置100运动,以使植入针110的针头部分111以特定角度对准目标位置植入进给机构120;通过植入进给机构120植入进给机构120使得植入针110带动电极丝1运动到距离目标位置的表面的预定距离处;以及通过植入执行机构130驱动植入针110连同电极丝1向前运动。在植入针110完成植入操作之后,可以通过植入执行机构130驱动植入针110回撤。将电极丝1布置在电极丝1支架上包括:将电极丝1的头部区段布置在电极丝1支架上,并使得电极丝1的头端部伸出电极丝1支架成为所述自由端部;以及使得电极丝1的用于与电路连接的尾部区段与头部区段之间的部分区段悬空为非张紧的状态。
如图8A所示,电极丝1的前部区段布置在电极固定装置300上,并使得电极丝1的位于前端的接合部伸出电极固定装置300以便于与引导装置接合。电极丝1被固定在电极固定装置300上之后,在电极丝1的用于与电路连接的后部区段与前部区段之间,存在部分区段(下文称为“后段”)悬空为非张紧的状态(如图中所示的“悬空部分”)。
执行机构可以被大致定位在植入目标物到电极固定装置300的延长线上并驱动用于引导电极丝1的引导装置大致朝向目标物运动。如图所示,引导装置可以包括位于引导装置末端的针头部分111和用于安装针头部分111的针管部分112,针头部分111可以以例如粘接或套接等方式安装在针管部分112上。执行机构可以被定位在针管部分112的顶端,从而经由驱动针管部分112运动来驱动针头部分111。在引导装置与被固定在电极固定装置300上的电极丝1的接合部相接合之后,执行机构驱动引导装置继续例如向下运动以牵引电极丝1,即对电极丝1的前端施加拉力,从而将电极丝1至少部分地从电极固定装置300上分离,如图8B所示。引导装置可以在执行机构的 驱动下朝着目标物继续向下运动,以继续通过电极丝1的前端对电极丝1施加拉力,从而可以使得电极丝1完全脱离电极固定装置300,如图8C所示。由于电极丝1的后段悬空(未紧密固定在电极固定装置300上)并且后段为非张紧的状态,因此,在电极丝1完全脱离电极固定装置300之后,在电极丝1的前端到其后端(未示出,指用于连接电路的端部)之间也呈非张紧状态地被悬挂。
在植入针110接合到电极丝1的自由端部之后,通过喷雾装置500向悬挂在植入针110旁的电极丝1施加喷雾,以使得电极丝1的头部区段贴附在植入针110上。
喷雾装置500可以被定位为面向电极丝1的与电极固定装置300分离的部分(特别是面向靠近前端的区段部分)并面向引导装置,并且喷雾装置500可以被定位为能够喷射具有大致从电极丝1的靠近前端的区段部分到引导装置的指向的喷射力的液体,如图8D所示,以便电极丝1的至少靠近前端的区段部分在喷射液体的作用下贴附于引导装置,如图8E所示。喷雾装置500使液体以被雾化的状态被喷射。喷射的液体可以包括纯水或适用于目标物的溶液。
通过设置的喷雾装置500使得电极丝1的至少靠近前端的区段部分贴附于引导装置,能够避免对目标物的生物组织形成较大的切口损伤。此外,通过喷射液体还能带来进一步的技术效果。在引导装置与被固定在电极固定装置300上的电极丝1的接合部相接合、并且在引导装置使得电极丝1完全脱离电极固定装置300之后,如图8C所示,电极丝1在自身重力的作用下,可能使得其接合部从引导装置上脱落,从而导致不期望的电极丝1与引导装置分离的后果。而通过喷射液体使得电极丝1贴附于引导装置之后,即使得电极丝1处于图8E所示的状态后,可加强电极丝1与引导装置之间的接合,避免因电极自身重力导致的电极丝1从引导装置上脱落。
在本实施例中,控制植入装置100运动包括:使植入装置100在弧状导轨220上滑移并且使弧状导轨220围绕法向于弧状导轨220的弧线延伸穿过弧状导轨220中心的转动轴线转动,和/或使可在空间中自由运动的机械臂210运动,以改变植入针110的针头部分111的朝向。
在对植入装置100和电极丝1进行观察时,可以调节第一光源410的照射角度、照射强度和/或光源颜色,以及调节第一相机430和/或第二相机440的成像参数、位置和/或光路指向,以使得第一相机430和第二相机440能够获得各自的清晰成像。此外,可以调节第二光源420的照射角度、照射强度和/或光源颜色,以及调节脑部表面相机450的成像参数、位置和/或光路指向,以使得脑部表面相机450能够获得清 晰成像。
在由处理装置控制植入装置100运动时,可以控制植入装置100沿纵向运动直至针头部分111的尖端接触到脑部表面停止,并在第三图像中标记针头部分111的尖端位置作为后续控制植入装置100运动以使植入针110的针头部分111对准目标位置的初始位置。此外,可以控制植入装置100沿纵向运动直至针头部分111的尖端接触到脑部表面停止,再控制植入装置100沿纵向回撤所述预定距离,以使得植入针110带动电极丝1运动到距离目标位置的表面的预定距离处。为了确定针头部分111的尖端已接触到脑部表面,可以利用在针头部分111的尖端接触到目标位置的表面即被接通的探测电路来探测针头部分111的尖端接触到目标位置的表面。在此,可以利用针头部分111上的微动电机微调针头部分111的XY位置,将落点对准可植入区域中的点。对准植入点后,植入装置100中的植入进给机构120使针头部分111缓慢地朝着目标位置,在接触到脑表面之后,将植入针110回撤至预定高度,再驱动植入执行机构130使植入针110快速向下植入,其中,该预定高度与植入深度以及植入执行机构130的限定行程有关,例如,当植入深度为2mm,而植入执行机构130的限定行程为5mm时,则将植入针110抬到其尖端离脑部表面3mm处)。接着,快速地、例如以30m 2/s的速度回撤植入针110,使电极丝1脱离植入针110留在脑组织内。在植入针110回撤之后,可以对植入针110的针头部分111进行清洗。接着可以移动电极固定装置300,以进行下一次植入。
