本发明涉及医疗器械技术领域,尤其涉及一种动力装置、手术机器人及接合方法。
背景技术
微创手术是指利用腹腔镜、胸腔镜等现代医疗器械及相关设备在人体腔体内部施行手术的一种手术方式。相比传统手术方式,微创手术具有创伤小、疼痛轻、恢复快等优势。
随着微创手术技术与人工智能技术的发展,手术机器人拥有进行复杂手术的能力、手术结果的高稳定性、操作精准、出血少且术后并发症少等优势,机器人辅助微创手术逐渐成为微创外科手术的发展趋势之一。
目前的微创手术机器人可以根据医生的操作控制对应的动力装置工作,驱动相应的手术器械动作,从而进行相应的手术操作。但是,考虑到手术器械的消毒需要,手术器械通常采用可拆卸的方式安装到动力装置所在的设备主体部分,利用手术器械来接收动力装置的转矩。在现有的手术机器人安装过程中,当安装完手术器械或无菌适配器后,仅能采用编码器等方式确定电机的转动角度,无法判断手术器械或无菌适配器是否已与动力装置处于耦接的状态,导致手术器械无法根据医生的操作精确地完成预定的动作,在手术器械未耦接状态下的自检过程引起的器械关节的非预期摆动还可能带来手术风险。

从操作设备2可以包括机械臂21、设置于机械臂21上的动力装置100、设置于动力装置100上的手术器械200,以及套设手术器械200的长轴210上的套管22。机械臂21用于调节手术器械200的位置;动力装置100用于驱动手术器械200执行相应操作。可以理解,本发明实施例并不限定主从式手术机器人,手术机器人也可以是不区分主从设备、将操作功能集成在从操作设备的构造。
手术器械200主要包括长轴210、末端执行器211和器械驱动部212,手术器械200的末端执行器211用于伸入体内,并通过其位于远端的末端器械执行手术操作,和/或获取体内影像。手术器械200的长轴210穿设于套管22内,其末端执行器211伸出套管22外,并通过动力装置100驱动其执行操作。手术器械200的长轴210位于套管22内的区域可以根据需要设置为刚性区域或柔性区域,套管22也可以省略。
从操作设备2可以包括一个或多个机械臂21,一个机械臂21上可以设置一个或多个动力装置100,一个动力装置100上可以安装一个或多个手术器械200。
可以在仅具有一个手术器械200的机械臂21上,用一个动力装置100对接一个手术器械200,为该手术器械200提供执行相关操作的驱动力;可以在具有多个手术器械200的机械臂21上,用一个动力装置100同时对接多个不同的手术器械200,为多个手术器械200提供驱动力。
如图3所示,为了实现手术器械200的多种不同的手术操作,每个手术器械200包括多个第一输入盘51,例如51A-51F,用于与之对接的每个动力装置100也具有多个转动件10,转动件10由电机驱动进行转动,当手术器械200驱动地结合到对应的动力装置100后,不同的第一输入盘51与不同的转动件10驱动地结合,从而实现扭矩的传递。根据末端执行器211的不同,动力装置100驱动末端执行器211执行相关的手术操作。图3示出了手术器械200包括六个第一输入盘51A-51F的情形,在其他实施方式中,第一输入盘可以是其他数量的个数。手术操作可以包括控制长轴210 的远端进行偏摆、旋转、俯仰等操作,末端执行器211可以是手术钳、烧灼设备、剪削设备、成像设备等。

下面实施例以手术器械200的器械壳体213的远端安装在动力装置100的近端为例进行说明,此时,动力装置100上形成有供手术器械200远端的长轴210穿设的器械通道,手术器械200的第一输入盘51位于器械壳体213的远端,朝向末端执行器211,动力装置100的转动件10位于动力装置100的近端。可以理解的是,本发明同样适用于手术器械200的器械壳体213的近端安装在动力装置100的远端的情形,此时,手术器械200的第一输入盘51位于器械壳体213的近端,背向末端执行器211,动力装置100的转动件10位于动力装置100的远端。

为了检测动力装置100的驱动输出情况,以为手术器械200提供稳定可靠的驱动输入,结合图4A~5A所示,本实施例提供了一种动力装置100,该动力装置主要包括第一壳体100a、转动件10、轴向偏置件20、第一检测部件30以及控制器40,其中,第一壳体100a用于固定电机M,每个电机M与一个第一输入盘51驱动连接,被配置为为第一输入盘51提供转动的动力源。转动件10可转动地设置在第一壳体100a内,包括轴向的耦接端部10S,耦接端部10S暴露于第一壳体100a外,以供驱动输入接口50对接,驱动输入接口50作为手术器械200的动力输入接口,可以是手术器械200的一部分,也可以是独立于手术器械200外的部件,也可以是动力装置100的一部分。
轴向偏置件20被配置为为转动件10提供朝向手术器械200的弹性偏置,使得驱动输入接口50与转动件10对接时可以保持弹性接触,实现稳定的轴向接触,其在驱动输入接口50与转动件10耦接时产生进一步的形变而使形变量变大。本实施例的轴向偏置件20采用压簧,设于转动件10 的背向手术器械200的一侧(远端),与电机M的转轴M1相对固定,随转动件10的转动而转动,在转动件10未被按压时,轴向偏置件20的压缩量最小,当转动件10被压下时,轴向偏置件20的压缩量增大。
可以理解的是,在其他实施方式中,轴向偏置件20也可以采用其他可以产生形变的弹性件,如橡胶。又例如图4C所示,轴向偏置件20还可以设于转动件10的靠近手术器械200的一侧(近端),并采用拉簧,轴向偏置件20的一端与电机M的转轴M1相对固定,另一端与转动件10固定,并朝手术器械200侧拉动转动件10,在转动件10未被按压时,轴向偏置件20的伸长量最小,当转动件10被压下时,轴向偏置件20的伸长量增大,为了避免拉簧伸出转动件10外影响对接,可以在转动件10端部开设凹槽C,将拉簧设于凹槽C中。
第一检测部件30
在初始状态下,转动件10上未安装驱动输入接口50,在转动件10的轴向上,第一检测部件30的检测端与转动件10之间具有间隔,第一检测部件30被配置为检测转动件10或其上的某一部位在其轴向上的位置。控制器40被配置为:在转动件10的被检测部相对于预设位置(如图4A所示的A0位置)位于背向手术器械200的一侧时,判定驱动输入接口50未与转动件10的耦接端部10S耦接。其中,当转动件10在预设位置A0时,为驱动输入接口50与转动件10耦接的临界状态,此时,驱动输入接口50压缩轴向偏置件20,为手术器械200提供转矩。也就是说,只有在驱动输入接口50与转动件10耦接时,转动件10才位于预设位置A0,在其他情况下,转动件10都不在预设位置A0,驱动输入接口50无法与转动件10驱动连接。
其中,第一检测部件30检测转动件10在其轴向上的位置的方式有多种,可以是直接测得转动件10沿其轴向上的位移(也即位置)变化,也可以通过间接测量轴向偏置件20的形变量实现。
本实施例中,第一检测部件30检测转动件10沿其轴向上的位置变化实现,具体地,在转动件10的轴向上,第一检测部件30的检测端与转动件10之间具有间隔,第一检测部件30的检测端相对于转动件10设于背向手术器械200的一侧,即,设于转动件10的远端一侧,第一检测部件30 为非接触式感应器,被配置为检测转动件10的被检测部是否被感应到,例如,第一检测部件30采用接近传感器,与之相应地,控制器40被配置为:当第一检测部件30感应到转动件10的被检测部时,判定驱动输入接口50未与转动件10耦接。
如图4A所示,示出了手术器械耦接状态下的动力装置的内部结构示意图,如图4B所示,示出了本发明实施例1的一种手术器械非耦接状态下的动力装置的内部结构示意图,图5A示出了一种动力装置的主要结构示意图。驱动输入接口50与转动件10通过朝向彼此端面的凹特征与凸特征的配合而耦接。如图5A所示,当转动件10上方无驱动输入接口50时,轴向偏置件20处于初始形变状态,第一检测部件30与转动件10之间的距离较大,第一检测部件30无法检测到转动件10;如图4B中,当驱动输入接口50装入到转动件10上时,轴向偏置件20的形变量增大,当驱动输入接口50与转动件10上用于耦接的凹特征与凸特征没有对准时,驱动输入接口50朝向远端侧挤压转动件10,轴向偏置件20的形变量处于最大形变状态,导致第一检测部件30与转动件10之间的距离变小,转动件10沿其轴向上的实际位置A1已朝远端偏离预设位置A0,从而被第一检测部件30检测到,此时,控制器40判定驱动输入接口50未与转动件10耦接;如图4A中,当驱动输入接口50装入到转动件10上后,驱动输入接口50与转动件10上用于耦接的凹特征与凸特征处于对准状态而彼此配合时,转动件10朝向近端回弹一段距离,导致第一检测部件30与转动件10之间的距离增大,转动件10沿其轴向上的实际位置到达预设位置A0,无法再被第一检测部件30检测到,此时,控制器40判定驱动输入接口50与转动件10耦接。
图5A中,转动件10具有一圈环形的被检测部101,第一检测部件30被配置为检测被检测部101的被检测部101是否被感应到,控制器40被配置为:当被检测部101被检测部101被感应到时,判定驱动输入接口50未与转动件10耦接。图5A示出的是第一检测部件30的检测端正对转动件10的远端面情形,第一检测部件30位于转动件10的轴向的一侧,当转动件10被挤压朝增大轴向偏置件20的形变量的方向(即,背向手术器械200的方向)运动时,被检测部101到第一检测部件30的检测端的距离逐渐减小。可以理解的是,第一检测部件30的位置可以改变,例如,图5B示出了另一种动力装置,图5B中,转动件10具有一圈环形的被检测部101’, 第一检测部件30设于转动件10的径向外侧,朝向转动件10的中轴线摆放,用于检测被检测部101’的环形外周面,该环形外周面相比转动件10的临近外周面的径向尺寸更大,当转动件10被挤压朝增大轴向偏置件20的形变量的方向运动时,转动件10的被检测部101’可以从远处沿轴向运动至靠近第一检测部件30的检测端,被检测部101’到第一检测部件30的检测端的距离首先逐渐减小,在被检测部101’靠近第一检测部件30时可以被第一检测部件30检测到,在随后继续挤压转动件10的过程中,被检测部101’则会逐渐远离第一检测部件30的检测端,被检测部101’到第一检测部件30的检测端的距离会逐渐增大。第一检测部件30的位置可以被设置为当检测到正对被检测部101’时,转动件10到达预设位置A0,与之相应地,控制器40被配置为:当被检测部101’被检测到时,判定驱动输入接口50与转动件10耦接。这里,被检测部101’可以与被检测部101为同一对象,也可以是不同于被检测部101的另一部位。
可以理解的是,在其他实施方式中,第一检测部件30也可以不采用接近传感器,而是采用距离传感器代替,第一检测部件30被配置为检测其与被检测部101之间的距离,控制器40被配置为:当第一检测部件30检测到其与转动件10之间的距离小于预设距离时,判定驱动输入接口50未与转动件10耦接;当第一检测部件30检测到其与转动件10之间的距离等于预设距离时,判定驱动输入接口50与转动件10耦接;当第一检测部件30检测到其与转动件10之间的距离大于预设距离时,也判定驱动输入接口50未与转动件10耦接。接近传感器包括但不限于电容式、电感式、光电式传感器等,距离传感器包括但不限于光学传感器、红外传感器、超声波传感器等。
转接组件300
为了在手术机器人手术过程中提供合适的无菌环境,需要对无菌器械和有菌器械进行中间隔离,一般从操作设备2的机械臂21及动力装置100是有菌的,手术器械200需要是无菌的,本实施例在有菌的动力装置100与无菌的手术器械200之间配置转接组件300,具体使用时,转接组件300可以作为无菌罩的一部分,通过利用无菌罩将手术器械与设备的其他部位隔离开,可以对有菌的动力装置100和无菌的手术器械200进行隔离,动力装置100的动力(例如马达转矩输出)经过转接组件300传递到达手术 器械200,既可以驱动手术器械200执行相应的手术操作,又能保证无菌隔离效果。
通过在手术器械200上设有第一输入盘51,转接组件300上设有第二输入盘52,动力装置100上设有转动件10,转动件10的数量与手术器械200上的第一输入盘51、转接组件300上第二输入盘52的数量对应,使得每个第一输入盘51分别通过一个第二输入盘52与一个转动件10耦接。
如图6A~图7,本实施例中,转接组件300具体包括可拆卸地安装到第一壳体100a的第二壳体300a和可转动地设于第二壳体300a上的多个第二输入盘52,即52A-52F。在这种实施方式中,第一输入盘51、第二输入盘52组成驱动输入接口50,第二输入盘52仅作为驱动输入接口50的一部分,第一输入盘51、第二输入盘52、转动件10三者两两驱动接合才称之为驱动输入接口50与转动件10耦接,仅第二输入盘52与转动件10接合、第一输入盘51与第二输入盘52未接合则仍然属于驱动输入接口50与转动件10未耦接的情形,在此情形下,第一检测部件3仍然可以检测到转动件10。
作为一种优选的实施方式,第二输入盘52与转动件10通过朝向彼此端面的凹特征与凸特征的配合而耦接,设于手术器械200上的第一输入盘51与第二输入盘52通过朝向彼此端面的凹特征与凸特征的配合而耦接,以在转动件10与手术器械200之间传递转矩。其中,第二输入盘52具有沿第二壳体300a的轴向的自由度,也就是说,第二输入盘52既可以相对于第二壳体300a旋转,也可以沿第二壳体300a的轴向移动,这就使得第二输入盘52可以被轴向偏置件20弹性抵接并产生轴向位移,具有与转动件10接合和不结合的两种接触状态。
与之相应地,控制器40被配置为:在第二壳体300a安装到动力装置后,根据第一检测部件30的检测结果,判断第二输入盘52是否与转动件10耦接;在第二输入盘52与转动件10耦接,且手术器械200安装到动力装置后,根据第一检测部件30的检测结果,判断第一输入盘51是否与第二输入盘52耦接。这样,只需为每个转动件10设置一个第一检测部件30,即可同时实现转接组件300的第二输入盘52、手术器械200的第一输入盘51的接合状态的检测。
为了实现轴向的对接,转动件10的耦接端部10S具有第一耦合特征C1、C2,第二输入盘52的下表面(远端)设有第二耦合特征D1、D2,第二输入盘52的上表面(近端)设有第三耦合特征E1、E2,第一输入盘51的下表面(远端)设有第四耦合特征F1、F2,第一耦合特征C1、C2为凸特征或凹特征,第二耦合特征D1、D2相应地为与第一耦合特征C1、C2接合的凹特征或凸特征,第三耦合特征E1、E2为凸特征或凹特征,第四耦合特征F1、F2为与第三耦合特征E1、E2接合的凹特征或凸特征,第一耦合特征C1、C2与第二耦合特征D1、D2接合、第三耦合特征E1、E2与第四耦合特征F1、F2接合后,转动件10的转矩即可传递至第一输入盘51。
图6A示出了动力装置100及其转接组件300的结构示意图,示出的动力装置100包括六个转动件10,即10A-10F,多个转动件10安装在第一壳体100a内,每个转动件10受控制器40控制独立运动。每个控制器40分别独立控制和驱动手术器械200,例如各个转动件10分别控制手术器械100的旋转、偏摆、俯仰、末端器械开合等操作。在其他实施方式中,控制器40的数量也可以根据需要改变,例如,通过一个控制器40控制动力装置100内所有的转动件10转动。
结合图6A~7所示,转接组件300的第二壳体300a包括设于其近端的上壳体3001和设于其远端的下壳体3002,上壳体3001与下壳体3002配合构成多个容纳腔3011,每个容纳腔3011用于容纳一个第二输入盘52,上壳体3001具有用于限制第二输入盘52沿轴向朝远端运动的第一边缘部3010,下壳体3002具有用于限制第二输入盘52沿轴向朝近端运动的第二边缘部3020,第二输入盘52的轴向尺寸小于容纳腔3011,从而可在容纳腔3011内轴向运动。
结合图5A、6A和图6B,电机M的转轴M1自由端伸出转动件10,相比耦接端部10S更突出于转动件10外,转接组件300的第二输入盘52的轴心部位开设有轴孔H,当转接组件300安装到第一壳体100a后,转轴M1自由端插入到轴孔H内,轴孔H可以实现对转接组件300安装的预对准功能,有利于转动件10与第二输入盘52的径向对准。轴孔H也可以是凹槽,开设于第二输入盘52的远端所在面上。具体地,转轴M1的自由端固定有轴帽M11,将转动件10的中心开设有供转轴M1穿设的中心孔10h,轴帽M11固定在转轴M1的自由端并至少部分容纳在中心孔10h内,对转 动件10进行径向限位,转动件10在轴向偏置件20的作用下与轴帽M11在轴向上弹性抵接,轴帽M11容许转动件10在轴向上进行移动,但不能相对于转轴M1发生转动。
可以理解的是,转接组件300也非必须,在有的实施方式中,转接组件300也可以省略。如图8所示,第一输入盘51与转动件10直接对接而耦接。在这种情况下,驱动输入接口50包括设于手术器械200上的第一输入盘51,第一输入盘51与转动件10通过朝向彼此端面的凹特征与凸特征(C1、C2与F1、F2)的配合而耦接。与之相应地,控制器40被配置为:在手术器械200装入动力装置后,根据第一检测部件30的检测结果,判断第一输入盘51是否与转动件10耦接。这一检测过程与上面的过程一致,即,当转动件10的被检测部相对于预设位置A0位于背向手术器械200的一侧时,判定驱动输入接口50未与转动件10的耦接端部10S耦接。
信号端子P1、P2、P3
为了判断驱动输入接口50与转动件10的耦接状态,动力装置可以包括各种信号端子。如图6A,动力装置100的第一壳体100a上具有第一信号端子P1,该第一信号端子P1可与驱动输入接口50上的信号端子接触而导通,控制器40被配置为:根据第一信号端子P1与驱动输入接口50的信号端子导通的信号,判定驱动输入接口50装入动力装置。
在具有转接组件300的动力装置100中,转接组件300被配置为在转动件10与手术器械200之间传递转矩,转接组件300包括第二信号端子P2,第二信号端子P2同时贯穿第二壳体300a的近端和远端表面,当转接组件300安装到动力装置100的第一壳体100a后,其第二信号端子P2与第一壳体100a上的第一信号端子P1接触而导通,随后将手术器械200安装到转接组件300上,手术器械200上的第三信号端子P3可以在安装后与第二信号端子P2接触而导通,从而形成连接第一信号端子P1的通路。控制器40被配置为:根据第二信号端子P2与第一信号端子P1导通的信号,判定转接组件300已安装到第一壳体100a;在转接组件300安装到动力装置100的第一壳体100a后,根据手术器械200的第三信号端子P3与第一信号端子P1导通的信号,判定手术器械200已安装到转接组件300。
在不具有转接组件300的动力装置100中,当手术器械200安装到动力装置100的第一壳体100a后,其第三信号端子P3与第一信号端子P1接触而导通,控制器40被配置为:根据手术器械200的第三信号端子P3与第一信号端子P1导通的信号,判定手术器械200已安装到动力装置100。
指示装置301
尽管控制器40可以根据各信号端子的导通状态判断出转接组件300/手术器械200已安装,为了进一步方便操作者直观地观察到转接组件300、手术器械200的安装状态,如图6A和图7,本实施例的动力装置100还包括指示装置301,指示装置可以设于第二壳体300a的外壁上以便于观察到。由于第一壳体100a上设有第一信号端子P1,转接组件300具有第二信号端子P2,手术器械200具有第三信号端子P3,指示装置301设于转接组件300上,且与第二信号端子P2电连接,可以通过第二信号端子P2与第一信号端子P1所在的检测回路导通,从而根据转接组件300的第二输入盘52、手术器械200的第一输入盘51的耦接状态发出指示,指示装置301为指示灯,也可以是喇叭等。第二信号端子P2能在转接组件300安装到第一壳体100a后与第一信号端子P1导通,并能在手术器械200安装到转接组件300后与第三信号端子P3导通,控制器40被配置为:在转接组件300安装到第一壳体100a后,和/或,手术器械200安装到转接组件300后,根据第一检测部件30的检测结果切换指示装置的指示状态,例如,当检测到转接组件300的第二输入盘52与转动件10耦接时,指示装置301由亮转灭,当手术器械200的第一输入盘51与第二输入盘52耦接时,指示装置301由亮转灭。
第二检测部件60
如图5A所示,为了准确检测转动件10的零位,即初始位置,方便电机M的转动角度的精确控制,动力装置100还具有第二检测部件60,转动件10上相应地设有靶点部T。当电机M带动转动件10转动至零位,靶点部T转动至与第二检测部件60正对,由此判断转动件10已回零位,根据该零位,可以判断转动件10的转动角度,可以方便后续的手术器械200的安装和耦接。控制器40被配置为:在靶点部T随转动件10转动至被第二检测部件60检测到时,判定转动件10转动至零位。
靶点部T可以为贯穿转动件10轴向的通孔,第二检测部件60包括发射端61和接收端62,发射端61和接收端62沿转动件10的轴向上分别设于靶点部T的两侧,当发射端61发出的信号被接收端62接收到时则说明靶点部T转动至发射端61和接收端62之间,否则,则认为靶点部T不与第二检测部件60正对。这里,靶点部T可以设置在环形的被检测部101上,发射端61和接收端62分别位于被检测部101的轴向的两侧,将被检测部101夹设于其中,发射端61和接收端62之间形成为被检测部101预留的轴向运动间隙600。
在其他实施例中,靶点部T也可以为其他供追踪的标识,例如,靶点部T为磁体,第二检测部件60为霍尔传感器,通过利用霍尔传感器检测磁体在其附近产生的磁场的变化情况即可识别转动件10的转动角度,从而确定零位。
通常,在动力装置100上电时,电机M驱动转动件10转动至零位,可以在此过程中结合电机的编码器等确定零位的位置,也能判断电机M是否正常工作,同时也能避免电机M故障对后续转接组件300和手术器械200的安装状态的检测准确性的影响。控制器40被配置为:根据电机M的通电指令,控制转动件10转动直至靶点部T被第二检测部件60检测到,使转动件10停止在零位位置,在此之后,才开始安装驱动输入接口50。在有的实施方式中,动力装置100上电时转动件10不回零位。
在具有转接组件300的动力装置100中,转接组件300可拆卸地安装到第一壳体100a,转接组件300安装到与转动件10驱动接合后,也可以控制电机M驱动转动件10转动至零位,手术器械200的末端执行器211穿过套管22后各种关节被基本捋直,转接组件300与转动件10驱动接合后,当各转动件10位于零位时,转接组件300的第二输入盘52与捋直的手术器械200对应关节的第一输入盘51的凹/凸特征的位置正好正对,因此,在安装手术器械200前将转动件10回零位可以使得手术器械200安装到转接组件300后可以直接与转接组件300驱动接合,或只需小幅度纠正转动件10的转动角度即可与对应的第一输入盘51耦接,可以提高手术器械的接合效率。控制器40被配置为:在转接组件300安装到第一壳体100a后,且第一检测部件30检测到转接组件300的第二输入盘52与转动件10驱动接合时,控制转动件10朝零位的方向转动,使靶点部T被第二检测部件60 检测到。在有的实施方式中,在安装手术器械200前转动件10不回零位,则需要在安装完手术器械200后再使第一输入盘51与对应的第二输入盘52对准耦接,这一过程将会花费更多时间。
如图6A,转动件10包括第一转动件10A和第二转动件10B,每个转动件10分别对应一个驱动输入接口50、一个第一检测部件30和一个第二检测部件60,第一转动件10A包括被配置为驱动手术器械200的末端执行器执行俯仰、偏航、开合等非自转动作的转动件10,第二转动件10B为被配置为驱动手术器械200的末端执行器执行自转动作的转动件10。当转接组件300安装到第一壳体100a且第二输入盘52与转动件10驱动接合后,即可接着安装手术器械200,在手术器械200安装到转接组件300并与转接组件300驱动接合后,第一转动件10A可以转动至零位,而与第一转动件10A不同,第二转动件10B可以转动至靶点部T位于预设角度区间α内。该预设角度区间α即为操作部1a与从操作设备200的主从操作限位区间,当靶点部T位于预设角度区间α外,在接下来手术前进行主从对齐时,无法将操作部1a的姿态与从操作设备200的姿态对齐,导致主从对齐程序自动退出,会影响医生的操作体验,只有在靶点部T位于该预设角度区间α内,才可以进行下一步的主从对齐程序。
因此,控制器40可被配置为:在手术器械200安装到转接组件300后,且第一检测部件30检测到第一输入盘51与第一转动件10A耦接时,如果靶点部T被第二检测部件60检测到,则第一转动件10A不再转动,否则,控制第一转动件10A转动,直至靶点部T被第二检测部件60检测到;在手术器械200安装到转接组件300后,且第一检测部件30检测到第一输入盘51与第二转动件10B耦接时,如果靶点部T位于预设角度区间α内,则第二转动件10B不再转动,否则,控制第二转动件10B转动至靶点部T位于预设角度区间α内。预设角度区间α可以根据电机M的编码器等数据限定出,靶点部T是否位于预设角度区间α内,也可以根据电机M的转动角度等推算出。
在实际安装过程中,当转接组件300安装到第一壳体100a后,或者手术器械200安装到转接组件300后,一般难以做到第一耦合特征C1、C2与第二耦合特征D1、D2一次对准、第三耦合特征E1、E2与第四耦合特征F1、F2一次对准,本实施例的控制器40被进一步配置为:在转接组件300 安装到第一壳体100a后,第二输入盘52未与转动件10耦接时,控制转动件10按预置的第一方式转动,当转动件10转动至与第二输入盘52耦接时,中断转动件10的预置转动,该预置的第一方式可以是例如正向和反向转动进行扫描,如扫描M次,这里,将从初始位置朝正向转动至极限位置再返回初始位置称为扫描,将从初始位置朝正向扫描一次返回或朝反向扫描一次返回称为扫描一次,转动件10的单向扫描的角度不超过第一角度阈值a;随后,在第一输入盘51未与第二输入盘52耦接时,控制转动件10按预置的第二方式转动,当转动件10转动至与第一输入盘51耦接时,中断转动件10的预置转动,该预置的第二方式可以是例如正向和反向转动进行扫描,如扫描N次,转动件10的单向扫描角度不超过第二角度阈值b,其中,M、N均不少于1次。
由于在手术器械200的安装过程中,转动件10转动至与第二输入盘52耦接的第一时间即中断预置转动,可以避免器械在与动力装置100驱动接合后被意外驱动,避免器械对于人体的伤害。而且,安装转接组件300的过程中,在第二输入盘52耦接成功时第一时间中断预置转动,可以省去不必要的动作,提高安装效率。
转接组件300安装后,当第一耦合特征C1、C2与第二耦合特征D1、D2未对准时,轴向偏置件对转动件10施加的偏置力将第二输入盘52弹性抵接在第二壳体300a的近端内表面,通过控制转动件10正、反方向反复旋转,可使转动件10相对于第二输入盘52发生旋转,使第一耦合特征C1、C2与第二耦合特征D1、D2对准;同样地,在手术器械200安装后,当第三耦合特征E1、E2与第四耦合特征F1、F2未对准时,通过控制转动件10正、反方向反复旋转,可使第二输入盘52相对于第一输入盘51发生旋转,使第三耦合特征E1、E2与第四耦合特征F1、F2对准。其中,手术器械200装入前,转动件10可以带动转接组件300的第二输入盘52自由旋转,当手术器械200装入后,手术器械200也可能在没有耦合的状态下随转动件10转动,为避免造成末端执行器在伤口具有非受控的意外运动,第二角度阈值b小于第一角度阈值a。
可以理解的是,在有的实施方式中,控制器40也可以被配置为:当检测到转接组件300安装到第一壳体100a后,不论第二输入盘52是否与转动件10耦接,都控制转动件10正向和反向转动进行扫描,转动件10的单 向扫描角度不超过第一角度阈值a;当检测到手术器械200安装到转接组件300后,不论第一输入盘51是否与第二输入盘52耦接,都控制转动件10正向和反向转动进行扫描,转动件10的单向扫描角度不超过第二角度阈值b,第二角度阈值b也小于第一角度阈值a。
更进一步地,考虑到在手术器械200安装到转接组件300并与转接组件300驱动接合后,在一个实施方式中,第一转动件10A需要转动至零位,控制器40被配置为:在第一转动件10A与一个第二输入盘52耦接,且对应的第一输入盘51安装到对应的第二输入盘52后未与第一转动件10A耦接时,控制在第一转动件10A按预置的第三方式转动,在此过程中,一旦第一检测部件30检测到第一输入盘51与第二输入盘52耦接,立即中断第一转动件10A的预置转动,控制转动件10朝零位转动,当第一转动件10A转动至靶点部T被第二检测部件60检测到时停止转动;在第二转动件10B与另一个第二输入盘52耦接,且对应的第一输入盘51安装到对应的第二输入盘52后未与第二转动件10B耦接时,控制第二转动件10B按预置的第四方式转动,并在第二转动件10B转动至与对应的第一输入盘51耦接时,中断第二转动件10B的预置转动,并控制第二转动件10B转动至靶点部T位于预设角度区间α内。也就是说,一旦第一检测部件30检测到第一输入盘51与第二输入盘52耦接,不论转动件10是即将正转还是反转,都直接朝零位的方向转动,直至靶点部T被第二检测部件60检测到,零位的方位可以在动力装置100上电时结合编码器等确定。这样,可以使得转动件10在第一输入盘51与第二输入盘52耦接后以最短的时间和转动路径回到零位,不进行多余的动作,而无需等待转动件10扫描完某一角度阈值,提高了安装效率和安全性。
在有的实施方式中,在手术器械200安装到转接组件300,且第一检测部件30检测到第一输入盘51与第一转动件10A耦接时,第一转动件10A立即停止转动,不再回零位。控制器40被配置为:在第一转动件10A与一个第二输入盘52耦接,且对应的第一输入盘51安装到对应的第二输入盘52后未与第一转动件10A耦接时,控制第一转动件10A按预置的第三方式转动,并在第一转动件10A转动至与对应的第一输入盘51耦接时,中断第一转动件10A的预置转动,并停止转动第一转动件10A,不再控制转动件10朝零位转动;在第二转动件10B与另一个第二输入盘52耦接,且对应 的第一输入盘51安装到对应的第二输入盘52后未与第二转动件10B耦接时,控制第二转动件10B按预置的第四方式转动,并在第二转动件10B转动至与对应的第一输入盘51耦接时,中断第二转动件10B的预置转动,并控制第二转动件10B的靶点部T转动至预设角度区间α内。也就是说,一旦第一检测部件30检测到第一输入盘51与第二输入盘52耦接,不论转动件10是即将正转还是反转,都直接停止转动,等待下一步主从对齐指令。当手术器械200的所有驱动输入接口50均与动力装置对应的转动件10耦接,且第二转动件10B的靶点部T位于设角度区间α内时,则可进行下一步的主从对齐动作,将操作部1a的姿态与从操作设备2的姿态对齐。
另外,考虑到转接组件300安装到第一壳体100a后,即使控制转动件10正、反方向反复旋转M次后,第二输入盘52仍不能与转动件10耦接,或者,控制转动件10正、反方向反复旋转N次后,第一输入盘51仍不能与第二输入盘52耦接,如图6B,进一步地,本实施例的转接组件300还包括轴向振动件302,该轴向振动件302部分伸入容纳腔3011内,当第二输入盘52不能与转动件10耦接,或者第一输入盘51不能与第二输入盘52耦接时,可通过控制轴向振动件302沿转接组件300的轴向振动第二输入盘52,直至相应的耦合特征彼此接合,例如,轴向振动件302可以是线性电机,固定在第二壳体300a上,并可借助第二信号端子P2与控制器40电连接。
例如,可在每个第二输入盘52的外周面开设环向的凹部520,轴向振动件302一部分设于第二壳体300a内,另一部分伸入到凹部520内,当第二输入盘52与转动件10耦接、第二输入盘52与第一输入盘51耦接时,转动件10均在预设位置A0,轴向振动件302可不接触凹部520,因此不影响第二输入盘52的转动,而当转动件10不在预设位置A0时,轴向振动件302驱动第二输入盘52在轴向上小幅振动,并配合转动件10的正、反方向旋转,从而可以使转动件10、第二输入盘52、第一输入盘51三者耦接。因此,控制器40可被配置为:转接组件300安装后,当第一耦合特征C1、C2与第二耦合特征D1、D2未对准时,控制转动件10正、反方向反复旋转的同时,启动轴向振动件302,使转动件10相对于第二输入盘52发生旋转和轴向振动,使第一耦合特征C1、C2与第二耦合特征D1、D2对准;同样地,在手术器械200安装后,当第三耦合特征E1、E2与第四耦合特征F1、 F2未对准时,控制转动件10正、反方向反复旋转的同时,启动轴向振动件302,使第二输入盘52相对于第一输入盘51发生旋转和轴向振动,使第三耦合特征E1、E2与第四耦合特征F1、F2对准。
如图9,示出了本实施例的另一种转接组件300,考虑到在某些极端情况下,当转接组件300安装到第一壳体100a后,即使按照预置的方式转动转动件10后,转动件10始终与第二输入盘52呈未耦接的状态,二者的凹特征与凸特征并未结合而是保持错位状态,转动件10在轴向偏置件20的作用下带动未耦接的第二输入盘52克服转接组件300的第二壳体300a的反向摩擦力进行转动,容易让人误以为转动件10与第二输入盘52耦接。为了消除这种不真实的耦接状态,本实施例在第二壳体300a的正对第三耦合特征E1、E2所在面的表面(即第一边缘部3010)凸设有若干第二凸台3000,这些第二凸台3000沿每个容纳腔3011的周向间隔地布置,第二输入盘52的第三耦合特征E1、E2所在的面上凸设有若干第一凸台521,这些第一凸台521设于第二输入盘52的边缘,而且不会与第四耦合特征F1、F2接触,即,第一凸台521所在的圆的半径大于第四耦合特征F1、F2所在圆的半径中更大的一个,从而只会限制第二输入盘52与第二壳体300a的相对转动,而不会与手术器械200的第一输入盘51发生干涉。
当转接组件300安装到第一壳体100a后,在轴向偏置件20的偏置作用下,第二输入盘52被转动件10抵接在第二壳体300a的内表面,也即上壳体3001的内表面,第二输入盘52的第一凸台521嵌入第二壳体300a的第二凸台3000之间的间隔内,当转动件10在未耦接状态下带动第二输入盘52转动时,第一凸台521在第二凸台3000之间的间隔内转动至与被第二凸台3000阻挡,即使一个第二凸台3000无法施加足够的阻力使第二输入盘52短暂停止,当第一凸台521经过多个第二凸台3000的作用后可以对第二输入盘52减速,从而可以使转动件10与第二输入盘52真正耦接,当二者耦接后即可克服第一凸台521与第二凸台3000之间的阻力而带动第二输入盘52跟随转动。
实施例2
如图10,本实施例提供了一种检测手术机器人的动力装置的接合状态的方法,该动力装置100包括第一壳体100a,转动件10可转动地设置在第一壳体100a上,包括轴向的耦接端部10S,轴向偏置件20被配置为为转动 件10提供朝向手术器械200的弹性偏置,并在驱动输入接口50与转动件10耦接时形变量变大,第一检测部件30被配置为检测转动件10在其轴向上的位置。
通过在动力装置中采用第一检测部件30后,该检测方法包括:根据第一检测部件30的检测结果,判断驱动输入接口50是否与转动件10耦接。其中,该驱动输入接口50被配置为在与转动件10耦接时压缩轴向偏置件20,为手术器械200提供转矩。具体地,当转动件10的被检测部相对于预设位置位于背向手术器械200的一侧时,判定驱动输入接口50未与转动件10耦接;反之,当转动件10位于预设位置A0时,判定驱动输入接口50与转动件10耦接。
当手术机器人不具有转接组件300时,第一输入盘51与转动件10通过朝向彼此端面的凹特征与凸特征(C1、C2与F1、F2)的配合而耦接。驱动输入接口50包括设于手术器械200上的第一输入盘51,第一输入盘51与转动件10通过朝向彼此端面的凹特征与凸特征的配合而耦接。在手术器械200装入动力装置100后,该检测方法包括:根据第一检测部件30的检测结果,判断第一输入盘51是否与转动件10耦接。当转动件10的被检测部相对于预设位置A0位于背向手术器械200的一侧时,判定驱动输入接口50未与转动件10的耦接端部10S耦接。
当手术机器人包括转接组件300时,转接组件300作为动力装置100的一部分,在转接组件300安装到动力装置100后,该检测方法包括:根据第一检测部件30的检测结果,判断第二输入盘52是否与转动件10耦接;在第二输入盘52与转动件10耦接,且手术器械200安装到转接组件300后,根据第一检测部件30的检测结果,判断第一输入盘51是否与第二输入盘52耦接。
在一个实施方式中,第一检测部件30通过检测转动件10的被检测部101是否被感应到来判定驱动输入接口50的耦接状态。此时,该检测方法包括:当第一检测部件30感应到转动件10的被检测部101时,判定驱动输入接口50未与转动件10耦接;当第一检测部件30未检测到转动件10的被检测部101时,则判定驱动输入接口50与转动件10耦接。
在一个实施方式中,第一检测部件30通过检测其与被检测部101之间的距离来判定驱动输入接口50的耦接状态。此时,该检测方法包括:当第一检测部件30检测到其与转动件10之间的距离小于预设距离时,判定驱动输入接口50未与转动件10耦接;反之,则判定驱动输入接口50与转动件10耦接。
在一个实施方式中,第一检测部件30通过检测轴向偏置件20的形变量判定驱动输入接口50的耦接状态。此时,该检测方法包括:当第一检测部件30检测到轴向偏置件20的形变量小于或大于预设值时,判定驱动输入接口50未与转动件10耦接;反之,当第一检测部件30检测到轴向偏置件20的形变量等于预设值时,则判定驱动输入接口50与转动件10耦接。
在一个实施方式中,动力装置100还包括设于第一壳体100a上的第一信号端子P1,该第一信号端子P1可与驱动输入接口50上的信号端子接触而导通,从而实现电信号的传递。该检测方法包括:根据第一信号端子P1与驱动输入接口50的信号端子导通的信号,判定驱动输入接口50已装入动力装置;否则,则判定驱动输入接口50暂未安装或安装失败。
在不具有转接组件300的动力装置100中,当手术器械200安装到动力装置100的第一壳体100a后,其第三信号端子P3与第一信号端子P1接触而导通。该检测方法包括:根据第一信号端子P1与第三信号端子P3导通的信号,判定手术器械200已装入动力装置。
在一个实施方式中,动力装置100包括被配置为在转动件10与手术器械200之间传递转矩的转接组件300,转接组件300上具有第二信号端子P2,手术器械200上具有第三信号端子P3,第二信号端子P2可与第一壳体100a上的第一信号端子P1接触而电连接,也可以与手术器械200上的第三信号端子P3接触而电连接。该检测方法包括:根据第二信号端子P2与第一信号端子P1导通的信号,判定转接组件300已安装到第一壳体100a;在转接组件300安装到第一壳体100a后,根据手术器械200的第三信号端子P3与第一信号端子P1导通的信号,判定手术器械200安装到转接组件300。
在一个实施方式中,动力装置100还具有指示装置301,指示装置301设于转接组件300上,且与第二信号端子P2电连接。从而,第二信号端子 P2能在转接组件300安装到第一壳体100a后与第一信号端子P1导通,并能在手术器械200安装到转接组件300后与第三信号端子P3导通。该检测方法包括:在转接组件300安装到第一壳体100a后,和/或,在手术器械200安装到转接组件300后,根据第一检测部件30的检测结果,切换指示装置的指示状态。例如,指示装置301为指示灯时,当检测到转接组件300的第二输入盘52与转动件10耦接时,指示装置301由亮转灭,当手术器械200的第一输入盘51与第二输入盘52耦接时,指示装置301由亮转灭。在其他实施方式中,指示装置301也可以是喇叭或显示装置等。该指示装置301的指示信息也可以采用其他方式发出提醒,例如,通过主操作台1或独立的影像装置(如影像车)进行显示。
实施例3
如图11,本实施例提供了一种手术机器人的动力装置的接合方法,包括:
S01、将驱动输入接口50安装到动力装置的转动件10的耦接端部10S;其中,转动件10在轴向偏置件20的作用下与驱动输入接口50弹性抵接,驱动输入接口50可为手术器械200提供转矩;
S02、检测转动件10在其轴向上的位置;
S03、当检测结果表明转动件10的被检测部相对于预设位置位于背向手术器械200的一侧时,按预置的方式(如正向和/或反向)转动转动件10,以使转动件10沿其轴向移动至预设位置A0;当检测结果表明转动件10沿其轴向位于预设位置A0时,则驱动输入接口50与转动件10接合成功。
当手术机器人不具有转接组件300时,第一输入盘51与转动件10通过朝向彼此端面的凹特征与凸特征(C1、C2与F1、F2)的配合而耦接。驱动输入接口50包括设于手术器械200上的第一输入盘51,第一输入盘51与转动件10通过朝向彼此端面的凹特征与凸特征的配合而耦接。则在手术器械与动力装置的接合时,只需先将手术器械200安装到动力装置100的第一壳体100a,然后检测转动件10在其轴向上的位置,当转动件10不在预设位置A0时,按预置的某一方式,如正向和/或反向转动转动件10,直至转动件10沿其轴向移动至预设位置A0,第一输入盘51即完成与转动件10的耦接。
当手术机器人包括转接组件300时,转接组件300作为动力装置100的一部分,转接组件300包括具有轴向和周向的自由度的第二输入盘52,第二输入盘52与转动件10通过朝向彼此端面的凹特征与凸特征的配合而耦接,设于手术器械200上的第一输入盘51与第二输入盘52通过朝向彼此端面的凹特征与凸特征的配合而耦接。这种情况下,该接合方法包括转接组件300和手术器械200两个安装过程,首先需要将转接组件300安装到动力装置100的第一壳体100a,然后检测转动件10在其轴向上的位置,当转动件10的被检测部相对于预设位置位于背向手术器械200的一侧时,则按预置的第一方式,如正向和/或反向转动转动件10,以使转动件10沿其轴向移动至预设位置A0,即完成转接组件300的安装和第二输入盘52的耦接;随后,将手术器械200安装到转接组件300的第二壳体300a,然后检测转动件10在其轴向上的位置,当转动件10不在预设位置A0时,在第二输入盘52的挤压下转动件10的被检测部相对于预设位置A0位于背向手术器械200的一侧,则按预置的第二方式,如正向和/或反向转动转动件10,以使转动件10沿其轴向移动至预设位置A0,即完成手术器械200的安装和第一输入盘51的耦接。
通常,在动力装置100上电时,电机M驱动转动件10转动至零位,第二检测部件60被用来检测转动件10的零位,通过在转动件10上设有靶点部T,当电机M带动转动件10转动至零位,靶点部T转动至与第二检测部件60正对。在将驱动输入接口50安装到动力装置100的转动件10的耦接端部10S前,可以转动转动件10直至靶点部T被第二检测部件60检测到,使转动件10回零位,方便下一步操作。
靶点部T可以为贯穿转动件10轴向的通孔,第二检测部件60包括发射端61和接收端62,发射端61和接收端62沿转动件10的轴向上分别设于靶点部T的两侧,当发射端61发出的信号被接收端62接收到时则说明靶点部T转动至发射端61和接收端62之间,否则,则认为靶点部T不与第二检测部件60正对。这里,靶点部T可以设置在环形的被检测部101上,发射端61和接收端62分别位于被检测部101的轴向的两侧,将被检测部101夹设于其中,发射端61和接收端62之间形成为被检测部101预留的轴向运动间隙600。转动件10转动至零位,具体表现为,靶点部T被第二检测部件60检测到。
在其他实施例中,靶点部T也可以为其他供追踪的标识,例如,靶点部T为磁体,第二检测部件60为霍尔传感器,通过利用霍尔传感器检测磁体在其附近产生的磁场的变化情况即可识别转动件10的转动角度,从而确定零位。
除了在动力装置100上电时转动件10可能需要回零位,当转接组件300安装到第一壳体100a,且第二输入盘52与转动件10耦接成功后,转动件10也可能需要回零位。在安装手术器械200前将转动件10回零位可以使得手术器械200安装到转接组件300后可以直接与转接组件300驱动接合,或只需小幅度纠正转动件10的转动角度即可与对应的第一输入盘51耦接,可以提高手术器械的接合效率。具体地,当转接组件300安装到第一壳体100a后,且第一检测部件30检测到转接组件300的第二输入盘52与转动件10驱动接合时,控制转动件10朝零位的方向转动,使靶点部T被第二检测部件60检测到。在有的实施方式中,在安装手术器械200前转动件10不回零位,则需要在安装完手术器械200后再使第一输入盘51与对应的第二输入盘52对准耦接,这一过程将会花费更多时间。
转动件10包括第一转动件10A和第二转动件10B,每个转动件10分别对应一个驱动输入接口50、一个第一检测部件30和一个第二检测部件60,第一转动件10A包括被配置为驱动手术器械200的末端执行器俯仰、偏航、开合等非自转动作的转动件10,第二转动件10B包括被配置为驱动手术器械200的末端执行器执行自转动作的转动件10。在驱动输入接口50接合过程中,当手术器械200安装到转接组件300后,且第一检测部件30检测到驱动输入接口50与第一转动件10A耦接时,第一转动件10A可以转动至零位:如果靶点部T被第二检测部件60检测到,则第一转动件10A不再转动,否则,则控制第一转动件10A转动,直至靶点部T被第二检测部件60检测到,使第一转动件10A回零位;但在手术器械200安装到转接组件300后,且第一检测部件30检测到驱动输入接口50与第二转动件10B耦接时,如果靶点部T位于预设角度区间α内,则第二转动件10B不再转动,否则,控制第二转动件10B转动至靶点部T位于预设角度区间α内。预设角度区间α可以根据电机M的编码器等数据限定出,靶点部T是否位于预设角度区间α内,也可以根据电机M的转动角度等推算出。
当手术机器人包括转接组件300时,转接组件300的第二输入盘52具有轴向和周向的自由度。在转接组件300安装到第一壳体100a后,第二输入盘52未与转动件10耦接时,控制转动件10按预置的第一方式转动,当转动件10转动至与第二输入盘52耦接时,中断转动件10的预置转动,该预置的第一方式可以是例如正向和反向转动进行扫描,如扫描M次,这里,将从初始位置朝正向转动至极限位置再返回初始位置称为扫描,将从初始位置朝正向扫描一次返回或朝反向扫描一次返回称为扫描一次,转动件10的单向扫描的角度不超过第一角度阈值a;随后,在第一输入盘51未与第二输入盘52耦接时,控制转动件10按预置的第二方式转动,当转动件10转动至与第一输入盘51耦接时,中断转动件10的预置转动,该预置的第二方式可以是例如正向和反向转动进行扫描,如扫描N次,转动件10的单向扫描角度不超过第二角度阈值b,其中,M、N均不少于1次。第一角度阈值a大于第二角度阈值b,以避免造成末端执行器在伤口具有非受控的意外运动。
可以理解的是,在有的实施方式中,手术器械与动力装置的结合过程也可以是:当检测到转接组件300安装到第一壳体100a后,不论第二输入盘52是否与转动件10耦接,都控制转动件10正向和反向转动进行扫描,转动件10的单向扫描角度不超过第一角度阈值a;当检测到手术器械200安装到转接组件300后,不论第一输入盘51是否与第二输入盘52耦接,都控制转动件10正向和反向转动进行扫描,转动件10的单向扫描角度不超过第二角度阈值b,第二角度阈值b也小于第一角度阈值a。
更进一步地,考虑到在手术器械200安装到转接组件300并与转接组件300驱动接合后,在一个实施方式中,第一转动件10A需要转动至零位,手术器械与动力装置的结合过程也可以是:在第一转动件10A与一个第二输入盘52耦接,且对应的第一输入盘51安装到对应的第二输入盘52后未与第一转动件10A耦接时,控制在第一转动件10A按预置的第三方式转动,在此过程中,一旦第一检测部件30检测到第一输入盘51与第二输入盘52耦接,立即中断第一转动件10A的预置转动,控制转动件10朝零位转动,当第一转动件10A转动至靶点部T被第二检测部件60检测到时停止转动;在第二转动件10B与另一个第二输入盘52耦接,且对应的第一输入盘51安装到对应的第二输入盘52后未与第二转动件10B耦接时,控制第二转动 件10B按预置的第四方式转动,并在第二转动件10B转动至与对应的第一输入盘51耦接时,中断第二转动件10B的预置转动,并控制第二转动件10B转动至靶点部T位于预设角度区间α内。也就是说,一旦第一检测部件30检测到第一输入盘51与第二输入盘52耦接,不论转动件10是即将正转还是反转,都直接朝零位的方向转动,直至靶点部T被第二检测部件60检测到,零位的方位可以在动力装置100上电时结合编码器等确定。这样,可以使得转动件10在第一输入盘51与第二输入盘52耦接后以最短的时间和转动路径回到零位,不进行多余的动作,而无需等待转动件10扫描完某一角度阈值,提高了安装效率和安全性。
在有的实施方式中,在手术器械200安装到转接组件300,且第一检测部件30检测到第一输入盘51与第一转动件10A耦接时,第一转动件10A立即停止转动,不再回零位。手术器械与动力装置的结合过程也可以是:在第一转动件10A与一个第二输入盘52耦接,且对应的第一输入盘51安装到对应的第二输入盘52后未与第一转动件10A耦接时,控制第一转动件10A按预置的第三方式转动,并在第一转动件10A转动至与对应的第一输入盘51耦接时,中断第一转动件10A的预置转动,并停止转动第一转动件10A,不再控制转动件10朝零位转动;在第二转动件10B与另一个第二输入盘52耦接,且对应的第一输入盘51安装到对应的第二输入盘52后未与第二转动件10B耦接时,控制第二转动件10B按预置的第四方式转动,并在第二转动件10B转动至与对应的第一输入盘51耦接时,中断第二转动件10B的预置转动,并控制第二转动件10B的靶点部T转动至预设角度区间α内。也就是说,一旦第一检测部件30检测到第一输入盘51与第二输入盘52耦接,不论转动件10是即将正转还是反转,都直接停止转动,等待下一步主从对齐指令。当手术器械200的所有驱动输入接口50均与动力装置对应的转动件10耦接,且第二转动件10B的靶点部T位于设角度区间α内时,则可进行下一步的主从对齐动作,将操作部1a的姿态与从操作设备2的姿态对齐。
另外,考虑到转接组件300安装到第一壳体100a后,即使控制转动件10正、反方向反复旋转M次后,第二输入盘52仍不能与转动件10耦接,或者,控制转动件10正、反方向反复旋转N次后,第一输入盘51仍不能与第二输入盘52耦接,如图6B,进一步地,本实施例的转接组件300还 包括轴向振动件302,该轴向振动件302部分伸入容纳腔3011内,当第二输入盘52不能与转动件10耦接,或者第一输入盘51不能与第二输入盘52耦接时,可通过控制轴向振动件302沿转接组件300的轴向振动第二输入盘52,直至相应的耦合特征彼此接合,例如,轴向振动件302可以是线性电机,固定在第二壳体300a上,并可借助第二信号端子P2与控制器40电连接。
例如,可在每个第二输入盘52的外周面开设环向的凹部520,轴向振动件302一部分设于第二壳体300a内,另一部分伸入到凹部520内,当第二输入盘52与转动件10耦接、第二输入盘52与第一输入盘51耦接时,转动件10均在预设位置A0,轴向振动件302可不接触凹部520,因此不影响第二输入盘52的转动,而当转动件10不在预设位置A0时,轴向振动件302驱动第二输入盘52在轴向上小幅振动,并配合转动件10的正、反方向旋转,从而可以使转动件10、第二输入盘52、第一输入盘51三者耦接。因此,手术器械与动力装置的结合过程也可以是:转接组件300安装后,当第一耦合特征C1、C2与第二耦合特征D1、D2未对准时,控制转动件10按预置的方式正、反方向反复旋转的同时,启动轴向振动件302,使转动件10相对于第二输入盘52发生旋转和轴向振动,使第一耦合特征C1、C2与第二耦合特征D1、D2对准;同样地,在手术器械200安装后,当第三耦合特征E1、E2与第四耦合特征F1、F2未对准时,控制转动件10按预置的方式正、反方向反复旋转的同时,启动轴向振动件302,使第二输入盘52相对于第一输入盘51发生旋转和轴向振动,使第三耦合特征E1、E2与第四耦合特征F1、F2对准。

实施例5
如图13所示,本实施例提供了一种手术机器人的控制方法,该控制方法包括:
S11、根据第一检测部件30的检测结果,判断驱动输入接口50是否与转动件10耦接;
S12、当手术器械200的所有驱动输入接口50均与动力装置对应的转动件10耦接后,将操作部1a的姿态与从操作设备的姿态对齐,该姿态对齐步骤可以由控制器40执行,也可以由另一控制器执行。
转动件10包括第一转动件10A和第二转动件10B,第一转动件10A和第二转动件10B的每个分别对应一个第二输入盘52和第一输入盘51。为了方便进行下一步的主从对齐程序,当手术器械200的所有驱动输入接口50均与动力装置对应的转动件10耦接后,步骤S12将操作部1a的姿态与从操作设备2的姿态对齐前,还需要先检测第二转动件10B的靶点部T是否转动至预设角度区间α内,当第二转动件10B的靶点部T转动至预设角度区间α内时,将操作部的姿态与从操作设备的姿态对齐,否则,不执行姿态对齐步骤。除此之外,该控制方法还包括控制动力装置与手术器械结合的步骤,动力装置与手术器械结合的步骤在上述实施例3中已有详细的介绍。
可以理解的是,本实施例的步骤S11中的判断驱动输入接口50是否与转动件10耦接的依据包括但不限于依赖第一检测部件30的检测,第一检测部件30的检测结果也可以采用其他方式代替,例如,可以根据驱动输入接口50与转动件10之间的阻力矩判断,当二者之间的阻力矩达到预设阈值时,则认为二者耦接,否则判定为没有耦接;或者,也可以根据电机M的电流大小判断,当电机M的电流达到预设电流值时,则认为二者耦接,否则判定为没有耦接;又或者,也可以根据手术器械200的第一输入盘51 与转动件10之间的间距判断,当二者之间的间距小于预设距离阈值时,则认为二者耦接,否则,判定二者没有耦接。
