具体实施方式
现在参考附图,特别是图1和2,其示出一种活检设备10,所述活检设备10通常包括非侵入式的(例如非一次性的)驱动器组件12和一次性活检探针组件14。
参考图3,驱动器组件12和一次性活检探针组件14共同地包括流体管理系统16,所述流体管理系统16包括真空源18、第一真空路径20和第二真空路径22。真空源18和第一真空路径20被永久地关联到驱动器组件12,第二真空路径22被永久地关联到一次性活检探针组件14,从而有助于活检组织样本安全有效的收集,下面将详细说明。
在本文中,术语“非一次性”是指在装置的使用寿命内计划用于多个患者的装置,术语“一次性”是指在一个患者使用后计划被弃置的装置。还有,术语“真空路径”表示用于在两点之间实现真空的流体通道,该流体通道流经一个或多个部件,例如一个或多个管道、导管、联接器和插入装置。还有,术语“永久地关联”表示在部件的使用寿命内计划不可释放地附接在常规基础上的连接。所以,例如,包括真空源18和第一真空路径20的驱动器组件12整体上作为一个单元是可重复使用的,而一次性活检探针组件14和第二真空路径22整体上作为一个单元是可弃置的。
驱动器组件12包括被构造为且按人体工学被设计为由用户持握的壳体24。驱动器组件12包括(收容在壳体24内)真空源18、第一真空路径20、控制器26、机电动力源28和真空监视机构30。用户界面32被定位成安装在壳体24上,并且相对于壳体24可从外部接近。壳体24限定细长空腔241,所述细长空腔241被构造为在驱动器组件12安装到活检探针组件14时接收活检探针组件14的相应壳体57。
控制器26和机电动力源28、真空源18、用户界面32以及真空监视机构30连通地联接。控制器26可以包括例如微处理器及相关的存储器,所述微处理器及相关的存储器用于执行程序指令以实现与活检组织样本回收相关的功能,比如控制真空源18和机电动力源28的一个或多个部件。控制器26还可以执行程序指令来监视活检设备10的部件的一个或多个条件和/或位置,以及监视与驱动器组件12和活检探针组件14相关的流体管理系统16的状态。
用户界面32包括控制按钮321和可视指示器322,控制按钮321向用户提供活检设备10的各项功能的控制,可视指示器322提供活检设备10的部件的一个或多个条件和/或位置的状态的视觉反馈。
机电动力源28可以包括例如电源34(比如电池)和电驱组件36。电池34可以是例如充电电池。电池34给活检设备10中所有的电动部件提供电力,所以图中为简明起见没有示出这些电联接。例如,电池34电联接到真空源18、控制器26、用户界面32和电驱组件36。
在本实施例中,电驱组件36包括第一驱动器361和第二驱动器362,每个都分别联接到电池,并且,第一驱动器361和第二驱动器362中的每一个分别可控地电联接到用户界面32。
第一驱动器361可包括电机381和传动单元401(通过一根线示意性示出)。第二驱动器362可包括第二电机382和传动单元402(通过一根线示意性示出)。每个电机381,382可以是例如直流(DC)电机、步进电机等等。第一驱动器361的传动单元401被构造为例如带有旋转-线性运动转换器,比如蜗杆装置、齿条齿轮装置、螺线管滑动装置等等。第二驱动器362的传动单元402被构造为传递旋转运动。第一驱动器361和第二驱动器362中的每一个都可以包括齿轮、齿轮系、皮带/带轮装置等等中的一种或多种。
真空源18电联接到电池34,并具有用于建立真空的真空源端口181。真空源18可控地电联接到用户界面32。真空源18还可以包括例如由电机183驱动的真空泵182。真空泵182可以是例如蠕动泵、隔膜泵、注射泵等等。
驱动器组件12的第一真空路径20永久地关联到真空源18。第一真空路径20(有时也被称为非一次性真空路径)具有近端201和远端202,并包括例如导管203、第一单向阀204和颗粒过滤器205。近端201以流体连通的方式固定地联接真空源18,例如固定地联接真空源18的真空源端口181。参考图4A,远端202包括第一真空密封件206。在本实施例中,第一真空密封件206是围绕第一真空路径20的第一通道207的平坦邻靠表面。
第一单向阀204被构造和布置为允许负压流体流向真空源18,并防止正压流体远离真空源18流向第一真空路径20的远端202。第一单向阀204可以是例如随着流体流向真空源18而打开,随着流体远离真空源18反向流出而关闭的止逆阀,比如球阀或簧片阀。
在本实施例中,颗粒过滤器205设置在真空源18和第一真空路径20的远端202之间。颗粒过滤器205可以是例如由金属或塑料制成的网筛。但是可以预见的是,颗粒过滤器205可以设置在活检探针组件14的真空接收部件和真空源18之间的流体管理系统16中。
真空监视机构30联接到真空源18,从而在感测到的真空度低于阈值时关闭真空源18。真空监视机构30可以包括例如真空监视器和在控制器26上执行的控制程序、以及压力传感器301,所述压力传感器301联接到控制器26,并与第一真空路径20流体连通以探测第一真空路径20中的压力。例如,如果第一真空路径20内的真空度低于指示流体管理系统16中一种限制的预定值,则控制器26可以通过切断真空源18(例如关闭电机183)做出反应。或者,控制器26可以监视供应给电机183的电流,如果电流超过指示流体管理系统16中一种限制的预定值,则控制器26可以通过切断真空源18(例如关闭电机183)做出反应。
一次性活检探针组件14被构造为可释放地附接于驱动器组件12。在本文中,“可释放附接”是指不需要工具就能进行计划中的临时连接、随后又能相对于驱动器组件12操作一次性活检探针组件14的选择性分离的构造。
一次性活检探针组件14包括框架141,传动装置42、活检探针44和第二真空路径22安装在所述框架141上。活检探针44可驱动地联接到传动装置42,并且传动装置42可驱动地联接到驱动器组件12的机电动力源28。
在所示的实施例中,传动装置42包括与活检探针44的各种部件可驱动地接合的第一受驱单元421和第二受驱单元422。而且,第一受驱单元421与驱动器组件12的电驱组件36的第一驱动器361可驱动地接合。第二受驱单元422与驱动器组件12的电驱组件36的第二驱动器362可驱动地接合。
在所示的实施例中(例如参见图1-3),活检探针44包括样本篮441和切割器套管442。样本篮441具有帮助刺入组织的锋利尖端443,并且具有采用凹陷区域形式、用于接收活检组织样本的样本凹口444。样本篮441和切割器套管442被构造为可沿着纵向轴线445独立地运动。
在操作中,切割器套管442由第一受驱单元421线性地驱动以在样本篮441的样本凹口444之上沿着纵向轴线445来回移动。例如,第一受驱单元421可以线性滑动的形式与驱动器组件12的第一驱动器361可驱动地接合,然后在第一方向46(也就是朝着驱动器组件12的近端)上沿着纵向轴线445驱动切割器套管442以露出样本篮441的样本凹口444,并且沿与第一方向46相反的第二方向48驱动切割器套管442以切断垂落在样本凹口444中的组织。而且,第一受驱单元421和第二受驱单元422被构造为共同运行,以在穿刺射击手术(piercing shot operation)中沿着纵向轴线445共同推进样本篮441和切割器套管442,从而有助于将活检探针44插入纤维组织内。
第二受驱单元422可以包括柔性的带齿齿条50和齿轮系52。柔性的带齿齿条50连接到样本篮441,并且齿轮系52与柔性的带齿齿条50上的齿接合。在操作中,第二驱动器362将旋转运动传递给齿轮系52,接着齿轮系52与柔性的带齿齿条50接合以线性地移动样本篮441,从而将样本凹口444中获取的组织从患者体内传出。在缩回时,柔性的带齿齿条50收纳在卷绕单元54内,由此与刚性获取系统相比明显减少活检设备10的整体装置长度。每个得到的组织样本从患者体内传出,并由将组织样本从样本凹口444挖出的组织样本回收机构56收集。
在本实施例中,卷绕单元54和组织样本回收机构56与壳体57形成整体单元,所述壳体57为卷绕单元54和组织样本回收机构56所共有。壳体57附接至框架141。组织样本回收机构56将在后面更详细地描述。例如,如图2,5A和6-8所示,壳体57具有由曲面和平面组合而成的独特外形S1,其总体高度H1、长度L1和宽度W1尺寸一起定义壳体57的独特轮廓。
在本实施例中,第二真空路径22(有时也称为一次性真空路径22)具有第一端221和第二端222,并且包括例如导管223、第二单向阀224以及流体管理箱225。第一端221被构造为可移除地附接于驱动器组件12的第一真空路径20的远端202。第二端222以流体连通的方式和样本篮441联接,并且更具体地,以流体连通的方式和样本篮441的样本凹口444联接。
还参见图4B,一次性真空路径22的第一端221包括第二真空密封件226。当一次性活检探针组件14附接在驱动器组件12上时,驱动器组件12的第一真空密封件206以密封接合的方式接触一次性活检探针组件14的第二真空密封件226。第二真空密封件226是围绕第二真空路径22的第二通道227的柔顺(例如橡胶)环状构件。
第二单向阀224被构造和布置为允许负压流体从样本篮441朝向第二真空路径22的第一端221流动,并冗余地(与驱动器组件12的第一单向阀204相结合地)防止任何正压流体沿着从第二真空路径22的第一端221朝向样本篮441的方向流动。换句话说,第二单向阀224提供冗余的第二层级保护以防止任何正压到达样本篮441的样本凹口444。在本实施例中,第二单向阀224可以例如是鸭嘴阀,比如簧片阀,所述鸭嘴阀随着流体流出鸭嘴阀的嘴部而打开,随着逆流而关闭。如所示那样,第二单向阀224可以定位在第二真空路径22的第一端221处的第二真空密封件226内。
还参见图5A,流体管理箱225在第一端221和第二端222之间被流体地插入第二真空路径22中。流体管理箱225包括箱体58和包含在箱体58内的过滤器装置60,所述过滤器装置被构造为防止残余的活检生物材料(例如血液和颗粒物)从样本篮441的样本凹口444流到驱动器组件12的真空源18。
流体管理箱225的箱体58具有第一端口581和第二端口582,第二真空路径22在第一端口581和第二端口582之间延续。流体管理箱225的第二端口582联接到样本篮441。第二真空路径22的第二单向阀224和第二真空密封件226中的每一个均联接到流体管理箱225的第一端口581,并且在本实施例中被安装到流体管理箱225的箱体58的外表面上。
如图5A和5B所示,过滤器装置60包括多个并列布置的流体吸收层62(被单独标示为层621、622、623和624),每个流体吸收层621、622、623和624与相邻的流体吸收层间隔开,比如621对622,622对623,623对624。每个流体吸收层621、622、623和624具有各自的贯通开口641、642、643、644,其中多个流体吸收层62的贯通开口641、642、643、644中的相邻开口例如在X、Y和Z方向中的至少一个方向上彼此偏置,以形成穿过多个流体吸收层62的曲折开放的流体通道66。每个流体吸收层621、622、623和624可以是例如吸水纸。
如图5A和5C所示,过滤器装置60还可包括沿着定义第二通道227的第二真空路径22布置为与多个流体吸收层62流体串联的多孔过滤件68。当多孔过滤件68中增加数量的小孔70被残余的活检生物材料(比如血液和组织颗粒)堵塞时,多孔过滤件68增加对流体流动的限制。当流过流体管理箱225的流体体积减少到预定水平时,真空监视机构30感测到真空限制,并且控制器26响应以关闭真空源18。
参考图6-13,每个得到的组织样本被送出患者身体,并由组织样本回收机构56收集。一般来说,组织样本回收机构56通过挖出活检探针44的样本篮441的样本凹口444中的组织样本来收集已得到的组织样本。
参考图6-9,探针组件14的活检探针44包括围绕纵向轴线445同轴布置的活检套管(例如切割器套管442)以及样本篮441。带有样本凹口444的样本篮441被设置为由机电动力源28和第二驱动器362相对于活检套管442沿着纵向轴线445从样本采集位置72(图6和7所示)移动到组织样本回收区74(图6-8所示),更全面的描述可参考图3。还参考图10和12,样本凹口444是具有通常为半圆形截面的样本篮441的细长凹陷区域,并具有凹陷底部76、一对在凹陷底部76的相反侧隔开的细长边缘78,80、前过渡斜坡82和后过渡斜坡84。前过渡斜坡82和后过渡斜坡84位于细长凹陷区域(也就是样本凹口444)的相反两端。
在本实施例中,组织样本回收机构56包括样本箱接收器86、样本收集箱88、肘节机构(toggle mechanism)90和箱定位机构92。样本收集箱88被构造为可移除地插入样本箱接收器86。
可以与壳体57整体成型的样本箱接收器86包括中空导向器87,其具有能滑动地接收样本收集箱88的尺寸。所以,样本箱接收器86的构造使得样本箱接收器86允许样本收集箱88沿着基本上垂直于纵向轴线445的方向89(用双头箭头表示)双向运动。而且,样本箱接收器86的构造使得样本箱接收器86防止样本收集箱88沿着纵向轴线445在方向46或48上运动。
样本收集箱88限定单个收集腔94(参见图9),其被构造为接收多个组织样本,比如组织样本TS。样本收集箱88具有形成收集腔94的基座96、前壁98、后壁100、一对侧壁102,104以及可移除盖106。样本收集箱88还包括组织样本勺108。样本收集箱88被构造为当样本篮441沿着纵向轴线445在组织样本回收区74处移动时,从样本凹口444直接收集组织样本。至此,样本收集箱88的组织样本勺108被构造为与样本篮441的样本凹口444接合。
组织样本勺108被固定到基座96并从基座96向下凸出。组织样本勺108向前朝着样本收集箱88的前部110延伸到边缘112处。组织样本勺108具有组织收集内腔114,由活检探针组件14得到的每个组织样本TS都将通过该组织收集内腔114。组织收集内腔114起始于边缘112附近的开口116,并且延伸到收集腔94。组织样本勺108具有定位成邻近边缘112的斜坡面118。而且,组织样本勺108具有定位在开口116的相反侧上的第一肩部120和第二肩部122。
齿条124纵向地(例如垂直地)定位在样本收集箱88的后壁100上,从而与肘节机构90接合。
参考图6-9,肘节机构90被构造为帮助样本收集箱88安装到样本箱接收器86中,还帮助样本收集箱88从样本箱接收器86中移除。肘节机构90安装到壳体57并包括旋转齿轮126和弹簧128。旋转齿轮126具有旋转轴线130,例如附接于壳体57或与壳体整体成型的转轴。弹簧128联接在旋转齿轮126和壳体57之间,并偏心地安装在旋转齿轮126上,也就是在偏离旋转轴线130的位置。旋转齿轮126被设置用于在样本收集箱88被样本箱接收器86滑动地接收时,与样本收集箱88的齿条124驱动接合。
参考图6-8,肘节机构90被构造为限定转折点132,例如在所示方位中的12点位置处。图6示出样本收集箱88没有被安装到样本箱接收器86的中空导向器87中时肘节机构90的方位,弹簧128沿所示定位中的顺时针方向定位于超过12点的位置,由此限定肘节机构90的静止位置133。
图7示出样本收集箱88被安装(插入)到样本箱接收器86的中空导向器87中时肘节机构90的方位。当样本收集箱88被插入样本箱接收器86的中空导向器87时,样本收集箱88的齿条124接合旋转齿轮126,并使旋转齿轮126绕旋转轴线130沿所示定位中的逆时针方向旋转。当样本收集箱88被样本箱接收器86滑动地接收,弹簧128沿逆时针方向移动超过转折点132(例如12点位置)时,弹簧128通过旋转齿轮126产生偏置作用力134(例如向下的压力),以朝向纵向轴线445向下偏置样本收集箱88。所以在图7所示的方位中,当弹簧128沿逆时针方向移动超过12点位置时,偏置作用力134在样本收集箱88上施加向下压力,并且当样本收集箱88被安装到样本箱接收器86时维持偏置力134。
结合图7-9参考图11,箱定位机构92被构造为在提升位置136(图7所示)和下降位置138(图8,9所示)之间选择性地移动样本收集箱88。
箱定位机构92与机电动力源28可驱动地接合,以结合肘节机构90选择性地将样本收集箱88从提升位置136下降到下降位置138,从而将样本收集箱88的一部分(也就是组织样本勺108)定位成与样本凹口444滑动接合,进而当样本篮441移动到组织样本回收区74时,帮助从样本篮441中收集组织样本(也就是组织样本TS)。而且,机电动力源28可驱动地接合箱定位机构92和/或柔性的带齿齿条50,从而在从样本篮441上收集组织之前和之后,选择性地逆着肘节机构90所施加的偏置作用力134和箱定位机构92所施加的偏置作用力152将样本收集箱88从下降位置138提升到提升位置136,进而使样本收集箱88与样本篮441的样本凹口444分离。
更具体地,参考图6-8和11,箱定位机构92包括提升构件140、弹簧142、杠杆144、闩构件146和闩扣148。
参考图7和8,提升构件140被沿着纵向轴线445定位。提升构件140具有被定位成与样本收集箱88的斜坡面118接合的斜坡面150。弹簧142被定位在提升构件140和壳体57之间,从而在提升构件140上施加偏置作用力152,以沿着远离样本收集箱88的斜坡面118的方向偏置斜坡面150。
如图11所示,杠杆144从提升构件140沿垂直于纵向轴线445的方向154延伸。杠杆144具有被构造为接合机电动力源28的远端156,其可能是销158的形式。
机电动力源28可操作以沿着纵向轴线445在方向46上移动提升构件140,从而在提升构件140的斜坡面150沿着样本收集箱88的斜坡面118滑动时,将样本收集箱88提升远离纵向轴线445。同样的,机电动力源28可操作以沿着纵向轴线445在与第一方向46相反的方向48上移动提升构件140,从而在提升构件140的斜坡面150沿着样本收集箱88的斜坡面118滑动时,将样本收集箱88朝着纵向轴线445降下。
如图11所示,机电动力源28包括提升驱动器363,所述提升驱动器363具有联接到传动单元403(部分以线条示意性示出)的电机383,所述传动单元403通常终止于齿轮164和166。齿轮166包括用于接合杠杆144的销158的槽168。传动单元403向齿轮164提供旋转运动,然后使齿轮166旋转。传动单元403可以包括一个或多个齿轮、齿轮系、皮带/带轮装置等等,用于实现齿轮164的至少部分旋转。但是,齿轮166仅部分旋转,从而实现杠杆144的销158的线性平移,然后实现提升构件140的线性平移。
通过机电动力源28启动样本收集箱88的下降以用于样本收集(回收),其中机电动力源28的提升驱动器363的齿轮166沿一个方向旋转使杠杆144平移,然后使提升构件140沿着方向48平移,从而使样本收集箱88下降。施加到提升构件140上的偏置作用力152有助于斜坡面150沿着方向48远离样本收集箱88的斜坡面118。此时,组织样本勺108的第一肩部120和第二肩部122被定位成沿着纵向轴线445分别与样本篮441的样本凹口444的细长凹陷区域的一对隔开的细长边缘78,80滑动接合。
更具体地,参考图8和11,杠杆144及随后提升构件140沿方向48的平移导致样本收集箱88的倾斜斜坡面118滑下提升构件140的倾斜斜坡面150,并且具有边缘112的组织样本勺108朝着凹陷底部76移动进入样本篮441的样本凹口444的细长凹陷区域。参考图9和10,样本凹口444由机电动力源28沿方向46的连续传送将使组织样本勺108的边缘112沿着凹陷底部76以及沿着样本凹口444的细长边缘78,80之间的侧面滑动,从而挖出组织样本TS并将组织样本TS沿着路径170通过组织收集内腔114输送到样本收集箱88的收集腔94。样本收集箱88的肩部120,122被构造为沿样本篮441的上部间隔细长边缘78,80滑动,从而保证没有组织样本物质被推出样本凹口444。
样本收集箱88的提升发生在组织收集序列接近结束时。在组织收集序列接近结束时,由机电动力源28和第二驱动器362操作的样本篮441的样本凹口444沿方向46的进一步运动由样本篮441沿方向46与T形止挡172(其附接于提升构件140,参见图12)的驱动接合传递至提升构件140,这导致提升构件140沿方向46移动。样本收集箱88的勺边112抵达样本凹口444的倾斜前过渡斜坡82并被样本收集箱88的斜坡面118和样本凹口444的前过渡斜坡82之间的相互作用向上推,由此开始提升样本收集箱88。当提升构件140被样本凹口444的运动沿着方向46进一步移动时,勺边112离开样本凹口444和样本收集箱的斜坡面118,并停靠在提升构件140的斜坡面150上,这关闭样本收集箱88的组织收集内腔114,并且防止组织样本TS落出组织收集内腔114。
还有,提升驱动器363旋转以保证在样本凹口444所施加的作用力不足以完成平移时提升构件140完全沿方向46平移。更具体地,机电动力源28使提升驱动器363的齿轮166沿一个方向旋转从而使杠杆144沿方向46平移。所以,机电动力源28使提升构件140逆着弹簧142施加的偏置作用力152在第一方向46上沿纵向轴线445运动,从而在提升构件140的斜坡面150沿着样本收集箱88的斜坡面118滑动时提升样本收集箱88。
在样本凹口444沿方向46朝驱动器组件12的近端的传送完成时,T形止挡172的簧片舌174(参见图12)在样本凹口444的后过渡斜坡84处从真空路径22的第二端222除去残留的组织物质和碎屑,以保证足够的真空被吸入样本凹口444。
又参考图6-8,11和13,闩构件146被附接于提升构件140,或者与提升构件140整体形成。闩构件146从杠杆144沿方向46延伸,并具有远侧钩176。闩构件146被定位成与闩扣148接合,从而将提升构件140闩锁在闩锁输送位置,如图13所示,其对应于样本收集箱88的提升位置136。闩扣148可以附接于壳体57,或者与壳体57整体形成。
闩构件146的一个目的是在活检探针组件14的传送过程中保持杠杆144处于正确的插入位置,从而保证活检探针组件14正确地插入驱动器组件12。在活检探针组件14插入驱动器组件12之前,杠杆144被保持在闩锁输送位置,这是允许杠杆144的远端156上的销158插入提升驱动器363的槽168(也就是驱动器凹坑)的唯一位置(见图11)。在闩锁输送位置,如图13所示,杠杆144由闩构件146保持就位,闩构件146由来自弹簧142的压力(偏置作用力152)保持为逆着闩扣148的张力。所以,在闩锁输送位置活检探针组件14插入驱动器组件12导致杠杆144的远端156处的销158被定位在提升驱动器363的槽168(也就是驱动器凹坑)中。
闩构件146的第二个目的是防止意外重复使用一次性探针。作为动力源的一部分,提升驱动器363接合杠杆144的远端156处的销158,并使杠杆144沿方向46移动到完全缩回位置,接着使闩构件146与闩扣148脱离接合。闩构件146的张力被释放,从而导致闩构件146移出闩扣148所在的平面并防止闩构件146与闩扣148重新接触。由于弹簧142会沿方向48偏置提升构件140,因此,一旦活检探针组件14已经从驱动器组件12上移除,就可能不会重新建立图13所示的闩锁输送位置。因为闩锁输送位置是允许活检探针组件14插入驱动器组件12的唯一位置,所以防止了活检探针组件14被意外重复使用。
图14-23涉及用于给驱动器组件12的电池34自动充电的充电站700。图14单独示出充电站700,图15示出充电站700和可移除地安装在给驱动器组件12的电池34充电的充电站700上的驱动器组件12。还参考图16,充电站700包括基座702和充电坞704。
基座702具有足够的尺寸和重量以保证充电站700被放置在平坦水平表面(比如桌面)时的稳定。还有,基座702可以包括多个孔(未示出)以使得充电站700的基座702能以垂直方位被壁上安装。可以由橡胶或类似橡胶的材料制成的保护盘706被安装在基座702上,以使充电站700在没有永久安装在安装面上时能抵抗滑动。基座702包括凹形接收器708以帮助充电坞704以相对于基座702枢转的方式被安装。
充电坞704包括框架710,所述框架710具有被构造为与基座702的凹形接收器708匹配接合的凸起712。充电坞704通过螺钉714相对于基座702被引导,所述螺钉714穿过延伸通过凸起712的槽孔716,螺钉714的螺纹部分由基座702的凹形接收器708上的相应螺纹孔718接收。至少一个带螺纹的旋钮(图14中是两个)被旋入凸起712上相应的孔722中,所述旋钮旋紧时接合凹形接收器708从而保持充电坞704位于选定的相对于基座702的位置。旋钮的松开允许充电坞704相对于基座702枢转到所需要的角位置,例如20度。
框架710的长度和大体形状与活检探针组件14的框架141的长度和大体形状相对应。所以,当驱动器组件12放置在充电坞704上时,框架710闭合驱动器组件12的壳体24上的细长腔241以保护驱动器组件12的内部结构。
充电坞704包括安装到框架710上的壳体724。参见图14,壳体724具有由曲面和平面组成的独特外形S2,具有总的高度H2、长度L2和宽度W2,它们共同定义壳体724的独特轮廓。鼻部726向远侧延伸到壳体724,并通常对应于活检探针组件14的样本箱接收器86的位置。刻意地,壳体724的外形S2和活检探针组件14的壳体57的外形S1基本上相同(例如参见图5A),从而使活检探针组件14和充电坞704可互换地插入驱动器组件12的腔241内(例如比较图2和15)。
参见图17,一组电触点728被可接近地设置在壳体724的侧壁730处,以在驱动器组件12被安装在充电坞704上给电池34充电时,方便充电站700和驱动器组件12之间的电连通。相应地,如图18所示,一组对应的电触点732被定位成通过驱动器组件12的壳体24的细长腔241的侧壁可接近,以用于和充电坞704的一组电触点728接合。还有,手动软件重置开关735可以定位在电触点732附近,或者其他期望的位置,所述手动软件重置开关735能由用户使用小而尖的物体(比如掰直的回形针)手动激活,从而将控制器26重置,以重新启动由驱动器组件12所执行的软件。
参见图19,框架710具有通往壳体724的内腔738的接近开口736,并且壳体724的侧壁730具有通往壳体724的内腔738的接近开口740。参见图20,21A和21B,可移除盖742被设置成覆盖通往壳体724的内腔738的框架710的接近开口736,并且保持一组电触点728的板被设置成覆盖接近开口740。充电坞704的充电单元744安装在可移除盖742上。
参见图21A和21B,充电单元744包括和电源插头748电连通的印刷电路板746,印刷电路板746安装充电单元744的所有电子部件,例如保险丝、指示器发光二极管(LED)749等等。印刷电路板746包括适当的屏蔽以使得EMI干涉最小化。电源插头748的终端向上延伸穿过可移除盖742的上升部分,并且因此,由于不存在流体(例如清洁过程中过量的流体)被携带到终端上或附近的风险,而使终端免受腐蚀。
LED749被定位成不穿过可移除盖742的外表面,由此使设计更加清洁友好。LED749从内部照亮塑料的特征段,从而指示充电单元744正在供应正确的电流以及内置保险丝是起作用的。如果LED停止发光,则用户能知道是充电单元744有问题而不是活检驱动器组件12。
印刷电路板746还安装电触点728,以使得当可移除盖742安装到框架710上时,电触点728通过壳体724的侧壁730的接近开口740露出。而且,壳体724和可移除盖742被构造为使得当可移除盖742被联接到壳体724时(也就是当可移除盖742被附接到框架710时),充电单元744的所有电子部件都被定位在壳体724内部在内腔738中。
再参见图21C,通过供电单元750给电源插头748供电,供电单元又联接到交流电(AC)电源752,比如壁式电力插口。供电单元750被构造为给电源插头748供应直流电(DC)的变压器/整流器单元。作为给电源插头748供应直流电(DC)的一种替代方式,本领域技术人员会意识到供电单元750可以被构造为给电源插头748供应交流电(AC)的变压器,且整流器设置在印刷电路板746上。
图22是与充电站700相关联的控制系统的框图。如前面完整描述那样,控制器26连通地联接到驱动器361,362和363。位置传感器754连通地联接到控制器26,以将驱动器361,362和363的机械部件的当前位置反馈给控制器26。监视电路756监视充电坞704的电触点728和驱动器组件12的电触点732之间的连接,并且包括用于帮助电池34的充电的电压和电流控制电路。或者,可以预见的是,电压和电流控制电路可以被设置在充电坞704的充电单元744中。在将驱动器组件12安装到充电站700的充电坞704之前,安装在驱动器组件12上的任何活检探针组件14必须先从驱动器组件12上移除,从而腾出用于接收充电站700的充电坞704的壳体724的驱动器组件12的腔241。
当驱动器组件12被安装到充电站700后,一旦充电坞704的电触点728和驱动器组件12的电触点732之间建立连接,控制器26就调用监视子程序,如图23中的流程所述。
在步骤S1000,感测到充电站700的充电单元744的电触点728和驱动器组件12的电触点732之间形成连接。例如,监视电路756通过电触点732处电压的变化可以感测到充电站700的充电单元744的电触点728和驱动器组件12的电触点732之间形成连接。
在步骤S1002,基于步骤S1000中的感测,提供信号给驱动器组件12的控制器26,从而指示充电坞704的充电单元744的电触点728和驱动器组件12的电触点732之间已经形成连接。例如,充电单元744通过监视电路756可以给控制器26提供电压信号(例如数字“high”信号),从而指示充电坞704的充电单元744的电触点728和驱动器组件12的电触点732之间已经形成连接。
在步骤S1004,一旦从充电单元744接收到信号,控制器26就执行程序指令来确定驱动器组件12是否处于错误状态,也就是处于故障条件下。例如,如果驱动器361,362和363中的一个或多个的机械零件没有处于正确的位置来帮助驱动器组件12和活检探针组件14的联接,则就可能存在错误状态。
如果不存在错误状态,则整个程序前进到步骤S1006开始给电池34充电。
但是,如果在步骤S1004确定存在错误状态,则程序前进到步骤S1008,此时控制器26执行程序指令将驱动器组件12重置到初始状态。例如,控制器26可以命令机电动力源28的电动组件36的驱动器361,362和363回到初始状态。初始状态将机电动力源28的电动组件36的驱动器361,362和363的机械部件预定位,以对应新活检探针组件14的出厂预设状态,从而实现驱动器组件12和活检探针组件14之间正确的可驱动的机械联接。
然后,过程前进到步骤S1006给电池34充电。驱动器组件12的监视电路756例如通过调教电压和电流来调节充电坞704供应的直流电的电压,以给电池34充电。
由于通过在充电过程的初始阶段将驱动器组件12重置,在重新充电期间没有活检探针组件能被安装在驱动器组件12上,因此,这保证一旦驱动器组件12从充电站700取下,驱动器组件12就能够和新的活检探针组件14可驱动地联接。
虽然本发明已描述至少一个实施例,但是本发明能够在本公开的范围和精神内做进一步改动。所以本申请根据其一般原则意在覆盖本发明的任何变型、使用或改变。另外,本申请意在覆盖在本领域公知技术和常规实践的范围内的、属于本发明并落入后附权利要求限定之内的、本文没有公开的内容。
