图1至图3中所示的外壳12结合包括端部执行器300的可互换轴组件200示出,所述端部执行器包括被构造成能够可操作地支撑其中的外科钉仓304的外科切割和紧固装置。外壳12可被构造用于与可互换轴组件结合使用,所述可互换轴组件包括能够支撑不同尺寸和类型的钉仓的端部执行器,并具有不同的轴长度、尺寸和类型等。此外,外壳12也可有效地与多种其它可互换轴组件一起使用,所述其它可互换轴组件包括被构造成能够将其它动作和形式的能量(例如,射频(RF)能量、超声能量和/或动作)施加到能够与各种外科应用和外科手术结合使用的端部执行器布置的那些组件。此外,端部执行器、轴组件、柄部、外科器械和/或外科器械系统可利用任何一种或多种合适的紧固件来紧固组织。例如,包括可移除地存储在其中的多个紧固件的紧固件仓能够可移除地插入轴组件的端部执行器中和/或附接到轴组件的端部执行器。
图1示出了具有可操作地联接到其的可互换轴组件200的外科器械10。图2和图3示出了可互换轴组件200至外壳12或柄部组件14的附接。如图4所示,柄部组件14可以包括一对可互连柄部外壳段16和18,该对柄部外壳段可通过螺钉、按扣特征结构、粘合剂等互连。在所示布置中,柄部外壳段16、18配合以形成可由临床医生握持和操纵的手枪式握把部19。如将在下文更详细地讨论,柄部组件14在其中操作地支撑多个驱动系统,该多个驱动系统被构造成能够生成各种控制动作并将其施加到可操作地附接到其的可互换轴组件的对应部分。
现在参见图4,柄部组件14还可包括可操作地支撑多个驱动系统的框架20。例如,框架20能够可操作地支撑通常标示为30的“第一”或闭合驱动系统,该“第一”或闭合驱动系统可用于将闭合和打开动作施加到可操作地附接或联接到其的可互换轴组件200。在至少一种形式中,闭合驱动系统30可包括被框架20枢转地支撑的闭合触发器32形式的致动器。更具体地,如图4所示,闭合触发器32经由销33枢转地联接到外壳14。此类布置使得闭合触发器32能够由临床医生操纵,使得当临床医生握持柄部组件14的手枪式握把部19时,闭合触发器32可容易地从启动或“未致动”位置枢转到“致动”位置并且更具体地枢转到完全压缩或完全致动位置。闭合触发器32可被弹簧或其它偏压布置(未示出)偏压到未致动位置。在各种形式中,闭合驱动系统30还包括枢转地联接到闭合触发器32的闭合连杆组件34。如图4所示,闭合连杆组件34可包括由销35枢转地联接到闭合触发器32的第一闭合连杆36和第二闭合连杆38。第二闭合连杆38在本文中也可称为“附接构件”并且包括横向附接销37。
仍然参见图4,可观察到,第一闭合连杆36可在其上具有锁定壁或锁定端39,该锁定壁或锁定端被构造成能够与枢转地联接到框架20的闭合释放组件60配合。在至少一种形式中,闭合释放组件60可包括具有在其上形成的朝远侧突起的锁定爪64的释放按钮组件62。释放按钮组件62可被释放弹簧(未示出)沿逆时针方向枢转。当临床医生将闭合触发器32从其未致动位置朝向柄部组件14的手枪式握把部19按压时,第一闭合连杆36向上枢转至某个点,其中锁定爪64落入该点中以与第一闭合连杆36上的锁定壁39保持接合,从而阻止闭合触发器32返回未致动位置。参见图18。因此,闭合释放组件60有助于将闭合触发器32锁定在完全致动位置。当临床医生期望将闭合触发器32解锁以允许其被偏压到未致动位置时,临床医生只需枢转闭合释放按钮组件62,使得锁定爪64运动成与第一闭合连杆36上的锁定壁39脱离接合。当锁定棘爪64已运动成与第一闭合连杆36脱离接合时,闭合触发器32可枢转回到未致动位置。也可采用其它闭合触发器锁定和释放布置结构。
除上述之外,图13至图15示出了处于未致动位置的闭合触发器32,该未致动位置与轴组件200的打开或松开构型相关联,在该构型中,组织可定位在轴组件200的钳口之间。图16至图18示出了处于致动位置的闭合触发器32,该致动位置与轴组件200的闭合或夹持构型相关联,在该构型中,组织被夹持在轴组件200的钳口之间。读者在将图14与图17比较之后将会知道,当闭合触发器32从其未致动位置(图14)向其致动位置(图17)运动时,闭合释放按钮62在第一位置(图14)与第二位置(图17)之间枢转。闭合释放按钮62的旋转可称为向上旋转,然而,闭合释放按钮62的至少一部分朝向电路板100旋转。参见图4,闭合释放按钮62可包括从其延伸的臂61和安装到臂61的磁性元件63,例如,永磁体。当闭合释放按钮62从其第一位置旋转到其第二位置时,磁性元件63可朝向电路板100运动。电路板100可包括被构造成能够检测磁性元件63的运动的至少一个传感器。在至少一个方面,例如,磁场传感器65可安装到电路板100的底部表面。磁场传感器65可被构造成能够检测由磁性元件63的运动引起的环磁场传感器65的磁场变化。磁场传感器65可例如与微控制器1500(图19)进行信号通信,该微控制器可确定闭合释放按钮62是处于其第一位置、其第二位置,还是/或者第一位置与第二位置之间的任何位置,该第一位置与闭合触发器32的未致动位置和端部执行器的打开构型相关联,该第二位置与闭合触发器32的致动位置和端部执行器的闭合构型相关联。
如在本公开通篇中所使用,磁场传感器可为磁场传感器、探测线圈、磁通门、光泵、核旋、超导量子干涉仪(SQUID)、霍尔效应、各向异性磁电阻、巨磁电阻、磁性隧道结、巨磁阻抗、磁致伸缩/压电复合材料、磁敏二极管、磁敏晶体管、光纤、磁光,以及基于微机电系统的磁传感器等。
在至少一种形式中,柄部组件14和框架20可以可操作地支撑在本文中称为击发驱动系统80的另一个驱动系统,该驱动系统被构造成能够将击发动作施加到附接到其的可互换轴组件的对应部分。击发驱动系统80在本文中也可称为“第二驱动系统”。击发驱动系统80可采用位于柄部组件14的手枪式握把部19中的电动马达82。在各种形式中,马达82可以是直流有刷驱动马达,其具有例如大约25,000RPM的最大转速。在其它布置中,马达可包括无刷马达、无绳马达、同步马达、步进马达、或任何其它合适的电动马达。马达82可由电源90供电,在一种形式中,该电源可包括可移除电源组92。如图4所示,例如,电源组92可包括近侧外壳部分94,该近侧外壳部分被构造用于附接到远侧外壳部分96。近侧外壳部分94和远侧外壳部分96被构造成能够可操作地支撑其中的多个电池98。电池98各自可包括例如锂离子(“LI”)电池或其它合适的电池。远侧外壳部分96被构造成能够以可移除方式可操作地附接到同样可操作地联接到马达82的控制电路板组件100。可使用可串联连接的多个电池98作为外科器械10的电源。此外,电源90可以是可替换的和/或可充电的。
如上文关于其它各种形式所概述,电动马达82可包括与齿轮减速器组件84可操作地交接的可旋转轴(未示出),该齿轮减速器组件被安装成与能够纵向运动的驱动构件120上的一组或一齿条的驱动齿122啮合接合。在使用中,电源90所提供的电压极性可沿顺时针方向操作电动马达82,其中由电池施加给电动马达的电压极性可被反转,以便沿逆时针方向操作电动马达82。当电动马达82沿一个方向旋转时,驱动构件120将沿远侧方向“DD”被轴向地驱动。当马达82被沿相反的旋转方向驱动时,驱动构件120将沿近侧方向“PD”被轴向地驱动。柄部组件14可包括开关,该开关被构造成能够使由电源90施加到电动马达82的极性反转。如同本文所述的其它形式一样,柄部组件14还可包括传感器,该传感器被构造成能够检测驱动构件120的位置和/或驱动构件120运动的方向。
马达82的致动可由枢转地支撑在柄部组件14上的击发触发器130控制。击发触发器130可在未致动位置和致动位置之间枢转。击发触发器130可被弹簧132或其它偏压布置结构偏压到未致动位置中,使得当临床医生释放击发触发器130时,击发触发器可被弹簧132或偏压布置结构枢转到或以其它方式返回未致动位置。在至少一种形式中,如上文所讨论,击发触发器130可定位在闭合触发器32“外侧”。在至少一种形式中,击发触发器安全按钮134可由销35枢转地安装到闭合触发器32。安全按钮134可定位在击发触发器130和闭合触发器32之间,并且具有从其突起的枢转臂136。参见图4。当闭合触发器32处于未致动位置时,安全按钮134被容纳在柄部组件14中,在此情况下,临床医生不能容易地接近安全按钮并使安全按钮在阻止击发触发器130的致动的安全位置和其中可击发击发触发器130的击发位置之间运动。当临床医生按压闭合触发器32时,安全按钮134和击发触发器130向下枢转,随后可被临床医生操纵。
如上文所讨论,柄部组件14可包括闭合触发器32和击发触发器130。参见图14至图18A,击发触发器130能够可枢转地安装到闭合触发器32。闭合触发器32可包括从其延伸的臂31,击发触发器130可围绕枢轴销33可枢转地安装到臂31。如上文所概述,当闭合触发器32从其未致动位置(图14)运动到其致动位置(图17)时,击发触发器130可向下下降。在安全按钮134已运动到其击发位置之后,主要参见图18A,可按压击发触发器130,以操作外科器械击发系统的马达。在各种实例中,柄部组件14可包括跟踪系统,例如,系统800,该跟踪系统被构造成能够确定闭合触发器32的位置和/或击发触发器130的位置。主要参照图14、图17和图18A,跟踪系统800可包括磁性元件(例如,永磁体802),该磁性元件安装到从击发触发器130延伸的臂801。跟踪系统800可包括一个或多个传感器,例如,第一磁场传感器803和第二磁场传感器804,这些传感器可被构造成能够跟踪磁体802的位置。
读者在将图14与图17比较之后将会知道,当闭合触发器32从其未致动位置运动到其致动位置时,磁体802可在与第一磁场传感器803相邻的第一位置和与第二磁场传感器804相邻的第二位置之间运动。
读者在将图17与图18A比较之后将进一步知道,当击发触发器130从未击发位置(图17)向击发位置(图18A)运动时,磁体802可相对于第二磁场传感器804运动。传感器803和804可跟踪磁体802的运动,并且可与电路板100上的微控制器进行信号通信。微控制器可利用来自第一传感器803和/或第二传感器804的数据,确定磁体802沿着预定义的路径的位置,并且微控制器可基于该位置,确定闭合触发器32是处于其未致动位置、其致动位置、还是其未致动位置和其致动位置之间的位置。相似地,微控制器可利用来自第一传感器803和/或第二传感器804的数据,确定磁体802沿着预定义的路径的位置,并且微控制器可基于该位置,确定击发触发器130是处于其未击发位置、其完全击发位置、还是其未击发位置和其完全击发位置之间的位置。
如上所述,在至少一种形式中,能够纵向运动的驱动构件120具有在其上形成的一齿条的齿122,以用于与齿轮减速器组件84的相应驱动齿轮86啮合接合。至少一种形式还包括能够手动致动的“应急”组件140,该组件被构造成能够使临床医生能够在马达82变得失能的情况下手动地缩回能够纵向运动的驱动构件120。应急组件140可包括杠杆或应急柄部组件14,该杠杆或应急柄部组件被构造成能够被手动地枢转成与同样设置在驱动构件120中的齿124棘轮接合。因此,临床医生可使用应急柄部组件14手动地缩回驱动构件120,以使驱动构件120沿近侧方向“PD”做棘轮运动。现为美国专利8,608,045的美国专利申请公布US2010/0089970公开了应急布置和同样可用于本文所公开的各种器械的其它部件、布置和系统。名称为“POWERED SURGICAL CUTTING AND STAPLING APPARATUS WITH MANUALLYRETRACTABLE FIRING SYSTEM”的美国专利申请序列号12/249,117(美国专利申请公布2010/0089970,现为美国专利8,608,045)据此全文以引用方式并入。
现在参见图1和图7,可互换轴组件200包括外科端部执行器300,该外科端部执行器包括被构造成能够可操作地支撑其中的钉仓304的细长通道302。端部执行器300还可包括砧座306,该砧座相对于细长通道302可枢转地支撑。可互换轴组件200还可包括关节运动接头270和关节运动锁350(图8),该关节运动锁可被构造成能够将端部执行器300相对于轴轴线SA-SA可释放地保持在期望的位置。有关端部执行器300、关节运动接头270和关节运动锁350的构造和操作的细节阐述于提交于2013年3月14日的名称为“ARTICULATABLESURGICAL INSTRUMENT COMPRISING AN ARTICULATION LOCK”的美国专利申请序列号13/803,086(现为美国专利申请公布2014/0263541)中。提交于2013年3月14日的名称为“ARTICULATABLE SURGICAL INSTRUMENT COMPRISING AN ARTICULATION LOCK”的美国专利申请序列号13/803,086(现为美国专利申请公布2014/0263541)据此以引用方式并入本文。如图7和图8所示,可互换轴组件200还可包括由喷嘴部分202和203构成的近侧外壳或喷嘴201。可互换轴组件200还可包括闭合管260,该闭合管可用于闭合和/或打开端部执行器300的砧座306。现在主要参见图8和图9,轴组件200可包括脊210,该脊可被构造成能够可固定地支撑关节运动锁350的轴框架部分212。参见图8。脊210可被构造成能够:一,可滑动地支撑其中的击发构件220;二,可滑动地支撑围绕脊210延伸的闭合管260。脊210还被构造成能够可滑动地支撑近侧关节运动驱动器230。关节运动驱动器230具有远侧端部231,该远侧端部被构造成能够可操作地接合关节运动锁350。关节运动锁350与关节运动框架352交接,该关节运动框架能够可操作地接合端部执行器框架(未示出)上的驱动销(未示出)。如所指出的那样,有关关节运动锁350和关节运动框架的操作的更多细节可见于美国专利申请序列号13/803,086(现为美国专利申请公布2014/0263541)。在各种情况下,脊210可包括可旋转地支撑在底座240中的近侧端部211。在一种布置中,例如,脊210的近侧端部211具有在其上形成的螺纹214,以便通过螺纹附接到被构造成能够被支撑在底座240内的脊轴承216。参见图7。这种布置有利于将脊210可旋转地附接到底座240,使得脊210可以相对于底座240选择性地围绕轴轴线SA-SA旋转。
主要参见图7,可互换轴组件200包括闭合梭动件250,该闭合梭动件可滑动地支撑在底座240内,使得其可相对于底座240轴向运动。如图3和图7所示,闭合梭动件250包括被构造成能够附接到附接销37的一对朝近侧突起的钩252,该附接销附接到第二闭合连杆38,如将在下文更详细地讨论。闭合管260的近侧端部261联接到闭合梭动件250以用于相对于其旋转。例如,将U形连接器263插入闭合管260的近侧端部261中的环形狭槽262中,使其保留在闭合梭动件250中的竖直狭槽253内。参见图7。这种布置有助于将闭合管260附接到闭合梭动件250,以用于与闭合梭动件一起轴向行进,同时使闭合管260能够围绕轴轴线SA-SA相对于闭合梭动件250旋转。闭合弹簧268轴颈连接在闭合管260上,并且有助于沿近侧方向“PD”偏压闭合管260,从而有助于当轴组件可操作地联接到柄部组件14时将闭合触发器枢转到未致动位置中。
在至少一种形式中,可互换轴组件200还可包括关节运动接头270。然而,其它可互换轴组件可能无法进行关节运动。如图7所示,例如,关节运动接头270包括双枢轴闭合套管组件271。根据各种形式,双枢轴闭合套管组件271包括具有朝远侧突出的上柄脚273和下柄脚274的端部执行器闭合套管组件272。端部执行器闭合套管组件272包括马蹄形开孔275和插片276,其用于按以引用方式并入本文的提交于2013年3月14日的名称为“ARTICULATABLESURGICAL INSTRUMENT COMPRISING AN ARTICULATION LOCK”的美国专利申请序列号13/803,086(现为美国专利申请公布2014/0263541)中所述的各种方式接合砧座306上的开口插片。如本文更详细地描述,当砧座306打开时,马蹄形开孔275和插片276与砧座上的插片接合。上部双枢轴连杆277包括向上突出的远侧枢轴销和近侧枢轴销,这些枢轴销分别接合闭合管260上的朝近侧突出的上柄脚273中的上部远侧销孔以及朝远侧突出的上柄脚264中的上部近侧销孔。下部双枢轴连杆278包括向上突出的远侧枢轴销和近侧枢轴销,这些枢轴销分别接合朝近侧突出的下柄脚274中的下部远侧销孔以及朝远侧突出的下柄脚265中的下部近侧销孔。另外参见图8。
在使用中,闭合管260朝远侧(方向“DD”)平移,以(例如)响应于闭合触发器32的致动而闭合砧座306。通过下述方式闭合砧座306:朝远侧平移闭合管260且因此平移轴闭合套管组件272,从而使其按前述参考文献美国专利申请序列号13/803,086(现为美国专利申请公布2014/0263541)中所述的方式撞击砧座360上的近侧表面。也如该参考文献所详述,通过下述方式打开砧座306:朝近侧平移闭合管260和轴闭合套管组件272,从而使插片276和马蹄形开孔275接触并且推挤砧座插片以将砧座306抬起。在砧座打开位置,轴闭合管260运动到其近侧位置。
如上所述,外科器械10还可包括在美国专利申请序列号13/803,086(现为美国专利申请公布2014/0263541)中更详细描述的类型和构造的关节运动锁350,该关节运动锁可被构造和操作成能够选择性地将端部执行器300锁定就位。当关节运动锁350处于其解锁状态时,这种构造使端部执行器300能够相对于轴闭合管260旋转或做关节运动。在这种解锁状态下,端部执行器300可被定位并推压贴靠例如环绕患者体内手术部位的软组织和/或骨,以使端部执行器300相对于闭合管260做关节运动。端部执行器300也可通过关节运动驱动器230相对于闭合管260做关节运动。
同样如上所述,可互换轴组件200还包括击发构件220,该击发构件被支撑以便在轴脊210内轴向行进。击发构件220包括被构造成能够附接到远侧切割部分或刀杆280的中间击发轴部分222。击发构件220在本文中也可称为“第二轴”和/或“第二轴组件”。如图8和图9所示,中间击发轴部分222可在其远侧端部中包括纵向狭槽223,该纵向狭槽可被构造成能够接收远侧刀杆280的近侧端部282上的插片284。纵向狭槽223和近侧端部282可被设定尺寸并被构造成能够允许两者间的相对运动,并且可包括滑动接头286。滑动接头286可允许击发驱动装置220的中间击发轴部分222运动,以在不运动或至少基本上不运动刀杆280的情况下,使端部执行器300做关节运动。一旦端部执行器300已被适当地取向,中间击发轴部分222就可朝远侧推进,直到纵向狭槽223的近侧侧壁接触到插片284,以便推进刀杆280并击发定位在通道302内的钉仓。如图8和图9中可进一步看到的那样,轴脊210在其中具有细长的开口或窗口213,以利于把中间击发轴部分222装配进轴框架210以及插入该轴框架中。一旦中间击发轴部分222已被插入轴框架中,顶部框架段215就可与轴框架212接合,以封闭其中的中间击发轴部分222与刀杆280。有关击发构件220的操作的进一步描述可见于美国专利申请序列号13/803,086(现为美国专利申请公布2014/0263541)。
除上述之外,轴组件200可包括离合器组件400,该离合器组件可被构造成能够选择性地和可释放地将关节运动驱动器230联接到击发构件220。在一种形式中,离合器组件400包括围绕击发构件220定位的锁定衬圈或锁定套管402,其中锁定套管402可在接合位置和脱离位置之间旋转,在该接合位置,锁定套管402将关节运动驱动器360联接到击发构件220,在该脱离位置,关节运动驱动器360没有可操作地联接到击发构件200。当锁定套管402处于其接合位置时,击发构件220的远侧运动可使关节运动驱动器360朝远侧运动,并且因此,击发构件220的近侧运动可使关节运动驱动器230朝近侧运动。当锁定套管402处于其脱离位置时,击发构件220的运动不传递到关节运动驱动器230,并且因此,击发构件220可独立于关节运动驱动器230运动。在各种情况下,当击发构件220没有使关节运动驱动器230在近侧方向或远侧方向上运动时,关节运动驱动器230可被关节运动锁350保持就位。
主要参见图9,锁定套管402可包括圆柱形或至少基本上圆柱形的主体,该主体包括限定于其中的被构造成能够接收击发构件220的纵向开孔403。锁定套管402可包括沿直径相反的面朝内的锁定突起404和面朝外的锁定构件406。锁定突起404可被构造成能够与击发构件220选择性地接合。更具体地,当锁定套管402处于其接合位置时,锁定突起404定位在限定于击发构件220中的驱动凹口224内,使得远侧推力和/或近侧拉力可从击发构件220传递到锁定套管402。当锁定套管402处于其接合位置时,第二锁定构件406被接收在限定于关节运动驱动器230中的驱动凹口232内,使得施加到锁定套管402的远侧推力和/或近侧拉力可传递到关节运动驱动器230。实际上,当锁定套管402处于其接合位置时,击发构件220、锁定套管402和关节运动驱动器230将一起运动。另一方面,当锁定套管402处于其脱离位置时,锁定突起404可以不定位在击发构件220的驱动凹口224内,并且因此,远侧推力和/或近侧拉力可以不从击发构件220传递到锁定套管402。因此,远侧推力和/或近侧拉力可以不传递到关节运动驱动器230。在这种情况下,击发构件220可相对于锁定套管402和近侧关节运动驱动器230朝近侧和/或朝远侧滑动。
如图8至图12所示,轴组件200还包括可旋转地接收在闭合管260上的开关鼓500。开关鼓500包括中空轴段502,该中空轴段具有在其上形成的轴凸台504,以用于将向外突起的致动销410接收在其中。在各种情况下,致动销410延伸穿过狭槽267进入设置在锁定套管402中的纵向狭槽408,以在锁定套管402与关节运动驱动器230接合时,利于该锁定套管做轴向运动。旋转扭转弹簧420被构造成能够如图10所示接合开关鼓500上的凸台504以及喷嘴外壳203的一部分,以将偏压力施加到开关鼓500。参见图5和图6,开关鼓500还可包括限定于其中的至少部分周边的开口506,这些开口可被构造成能够接收从喷嘴半部202、203延伸的周边安装架204、205,并且允许开关鼓500和近侧喷嘴201之间的相对旋转,而不是平移。如这些图所示,安装架204和205还延伸穿过闭合管260中的开口266以坐置在轴脊210中的凹陷部211中。然而,喷嘴201旋转到某个点(在该点处,安装架204、205到达它们各自的狭槽506在开关鼓500中的端部)将导致开关鼓500围绕轴轴线SA-SA的旋转。开关鼓500的旋转最终将引起致动销410的旋转以及锁定套管402在其接合位置与脱离位置之间的旋转。因此,实质上,喷嘴201可用于以在美国专利申请序列号13/803,086(现为美国专利申请公布2014/0263541)中更详细描述的各种方式来使关节运动驱动系统与击发驱动系统可操作地接合和脱离接合。
也如图8至图12所示,例如,轴组件200可包括滑环组件600,该滑环组件可被构造成能够将电力传导至端部执行器300和/或从该端部执行器传导电力,并且/或者将信号传送至端部执行器300和/或从该端部执行器接收信号。滑环组件600可包括近侧连接器凸缘604和远侧连接器凸缘601,该近侧连接器凸缘安装到从底座240延伸的底座凸缘242,该远侧连接器凸缘定位在限定于轴外壳202、203中的狭槽内。近侧连接器凸缘604可包括第一面,并且远侧连接器凸缘601可包括第二面,其中第二面与第一面相邻定位,并能够相对于第一面运动。远侧连接器凸缘601可围绕轴轴线SA-SA相对于近侧连接器凸缘604旋转。近侧连接器凸缘604可包括限定于其第一面中的多个同心或至少基本上同心的导体602。连接器607可安装在连接器凸缘601的近侧侧面上,并可具有多个触件(未示出),其中每个触件对应于导体602中的一个并与其电接触。这种布置在保持近侧连接器凸缘604与远侧连接器凸缘601之间电接触的同时,允许这两个凸缘之间相对旋转。例如,近侧连接器凸缘604可包括电连接器606,该电连接器可使导体602与安装到轴底座240的轴电路板610进行信号通信。在至少一个实例中,包括多个导体的线束可在电连接器606与轴电路板610之间延伸。电连接器606可朝近侧延伸穿过限定于底盘安装凸缘242中的连接器开口243。参见图7。提交于2013年3月13日的名称为“STAPLE CARTRIDGE TISSUE THICKNESS SENSOR SYSTEM”的美国专利申请序列号13/800,067(现为美国专利申请公布2014/0263552)全文以引用方式并入。提交于2013年3月13日的名称为“STAPLE CARTRIDGE TISSUE THICKNESS SENSOR SYSTEM”的美国专利申请序列号13/800,025(现为美国专利申请公布2014/0263551)全文以引用方式并入。有关击滑环组件600的更多细节可见于美国专利申请序列号13/803,086(现为美国专利申请公布2014/0263541)。
如上文所讨论,轴组件200可包括近侧部分和远侧部分,该近侧部分可固定地安装到柄部组件14,该远侧部分能够围绕纵向轴线旋转。如上文所讨论,可旋转远侧轴部分可围绕滑环组件600相对于近侧部分旋转。滑环组件600的远侧连接器凸缘601可定位在可旋转的远侧轴部分内。而且,除上述之外,开关鼓500也可定位在可旋转的远侧轴部分内。当可旋转的远侧轴部分旋转时,远侧连接器凸缘601和开关鼓500可彼此同步地旋转。另外,开关鼓500可相对于远侧连接器凸缘601在第一位置与第二位置之间旋转。当开关鼓500处于其第一位置时,关节运动驱动系统可与击发驱动系统可操作地脱离接合,因此,击发驱动系统的操作可不使轴组件200的端部执行器300进行关节运动。当开关鼓500处于其第二位置时,关节运动驱动系统能够可操作地与击发驱动系统接合,因此,击发驱动系统的操作可以使轴组件200的端部执行器300做关节运动。当开关鼓500在其第一位置和其第二位置之间运动时,开关鼓500相对于远侧连接器凸缘601运动。在各种实例中,轴组件200可包括被构造成能够检测开关鼓500的位置的至少一个传感器。现在参见图11和图12,远侧连接器凸缘601可包括例如磁场传感器605,并且开关鼓500可包括磁性元件,例如永磁体505。磁场传感器605可被构造成能够检测永磁体505的位置。当开关鼓500在其第一位置和其第二位置之间旋转时,永磁体505可相对磁场传感器605运动。在各种实例中,磁场传感器605可检测当永磁体505运动时产生的磁场变化。磁场传感器605可与例如轴电路板610和/或柄部电路板100进行信号通信。基于来自磁场传感器605的信号,轴电路板610和/或柄部电路板100上的微控制器可确定关节运动驱动系统是与击发驱动系统接合还是脱离。
再次参见图3和图7,底座240包括在其上形成的至少一个、优选地两个锥形附接部分244,该锥形附接部分能够被接收在对应的燕尾形狭槽702内,这些燕尾形狭槽在框架20的远侧附接凸缘部分700内形成。每个燕尾形狭槽702可以是锥形,或换句话讲,可以略成V形,从而以坐置方式将附接部分244接收在其中。如图3和图7中可进一步看到的那样,轴附接耳状物226在中间击发轴222的近侧端部上形成。如将在下文更详细地讨论,例如,当可互换轴组件200联接到柄部组件14时,轴附接耳状物226被接收在纵向驱动构件120的远侧端部125中形成的击发轴附接支架126中,例如由图3和图6中所示。
各种轴组件采用闩锁系统710以可移除地将轴组件200联接到外壳12,并且更具体地,联接到框架20。如图7所示,例如,在至少一种形式中,闩锁系统710包括可动地联接到底座240的锁定构件或锁定轭712。在所示示例中,例如,锁定轭712为U形,其具有两个隔开的向下延伸的支脚714。支脚714各自具有在其上形成的枢轴耳状物716,这些枢轴耳状物能够被接收在底座240中形成的对应孔245中。这种布置有利于锁定轭712至底座240的枢转附接。锁定轭712可包括朝近侧突起的两个锁定耳状物714,这两个锁定耳状物被构造用于与框架20的远侧附接凸缘700中对应的锁定棘爪或沟槽704可释放地接合。参见图3。在各种形式中,锁定轭712被弹簧或偏压构件(未示出)沿近侧方向偏压。锁定轭712的致动可通过可滑动地安装在闩锁致动器组件720上的闩锁按钮722来实现,该闩锁致动器组件安装到底座240。闩锁按钮722可相对于锁定轭712沿近侧方向偏压。如将在下文更详细地讨论,锁定轭712可通过沿远侧方向偏压闩锁按钮而运动到解锁位置,这也使锁定轭712枢转成不再与框架20的远侧附接凸缘700保持接合。当锁定轭712与框架20的远侧附接凸缘700“保持接合”时,锁定耳状物716保持坐置在远侧附接凸缘700中对应的锁定棘爪或沟槽704内。
当采用包括适于切割和紧固组织的本文所述类型的端部执行器以及其他类型的端部执行器的可互换轴组件时,可能有利的是防止可互换轴组件在端部执行器致动期间不经意地从外壳脱离。例如,在使用中,临床医生可致动闭合触发器32以抓持目标组织并将其操纵至期望的位置。一旦目标组织以期望取向定位在端部执行器300内,临床医生就可完全致动闭合触发器32,以关闭砧座306并将目标组织夹持在合适位置供切割与缝合。在该实例中,第一驱动系统30已被完全致动。在目标组织已被夹持在端部执行器300中之后,可能需要防止轴组件200不经意地从外壳12脱离。闩锁系统710的一种形式被构造成能够防止这种不经意的脱离。
如可在图7中最具体所见,锁定轭712包括至少一个且优选地两个锁定钩718,所述锁定钩能够接触在闭合梭动件250上形成的对应的锁定耳状物部分256。参见图13至图15,当闭合梭动件250处于未致动位置(即,第一驱动系统30未致动并且砧座306打开)时,锁定轭712可沿远侧方向枢转,以将可互换轴组件200从外壳12解锁。当处于该位置时,锁定钩718不接触闭合梭动件250上的锁定耳状物部分256。然而,当闭合梭动件250运动到致动位置(即,第一驱动系统30被致动并且砧座306处于闭合位置)时,锁定轭712被阻止枢转到解锁位置。参见图16至图18。换句话讲,如果临床医生试图将锁定轭712枢转到解锁位置,或者例如,锁定轭712不经意地以原本可能引起其朝远侧枢转的方式受到冲撞或发生接触,则锁定轭712上的锁定钩718将接触闭合梭动件250上的锁定耳状物256,并且防止锁定轭712运动到解锁位置。
现在将参照图3描述可互换轴组件200与柄部组件14的附接。要开始联接过程,临床医生可将可互换轴组件200的底座240定位在框架20的远侧附接凸缘700上方或附近,使得底座240上形成的锥形附接部分244与框架20中的燕尾形狭槽702对准。然后临床医生可沿垂直于轴轴线SA-SA的安装轴线IA运动轴组件200,以使附接部分244坐置成与对应的燕尾形接收狭槽702“可操作地接合”。这样做时,中间击发轴222上的轴附接耳状物226也将坐置在可纵向运动的驱动构件120中的支架126中,并且第二闭合连杆38上的销37的部分将坐置在闭合轭250中对应的钩252中。本文中所使用的术语“可操作地接合”在两个部件的上下文中是指这两个部件彼此充分地接合,使得一旦向其施加致动动作,这些部件就可执行其预期行动、功能和/或工序。
如上文所讨论,可互换轴组件200的至少五个系统能够可操作地与柄部组件14的至少五个对应系统联接。第一系统可包括框架系统,该框架系统将轴组件200的框架或脊与柄部组件14的框架20联接和/或对齐。另一系统可包括闭合驱动系统30,该闭合驱动系统可将柄部组件14的闭合触发器32与轴组件200的闭合管260和砧座306可操作地连接。如上文所概述,轴组件200的闭合管附接轭250可与第二闭合连杆38上的销37接合。另一系统可包括击发驱动系统80,该击发驱动系统可将柄部组件14的击发触发器130与轴组件200的中间击发轴222可操作地连接。
如上文所概述,轴附接耳状物226可与纵向驱动构件120的支架126可操作地连接。另一系统可包括电气系统,该电气系统可用信号通知柄部组件14中的控制器(例如,微控制器)轴组件(例如,轴组件200)已与柄部组件14可操作地接合,并且/或者(二)在轴组件200和柄部组件14之间传导功率和/或通信信号。例如,轴组件200可包括可操作地安装到轴电路板610的电连接器1410。电连接器1410被构造用于与柄部控制板100上的对应的电连接器1400配合接合。有关电路系统和控制系统的更多细节可见于美国专利申请序列号13/803,086,该专利申请的完整公开内容此前以引用方式并入本文。第五系统可由用于可释放地将轴组件200锁定到柄部组件14的闩锁系统组成。
再次参见图2和图3,柄部组件14可包括电连接器1400,该电连接器包括多个电触件。现在参见图19,电连接器1400可包括例如第一触件1401a、第二触件1401b、第三触件1401c、第四触件1401d、第五触件1401e和第六触件1401f。尽管所示示例利用了六个触件,但可设想出可利用多于六个触件或少于六个触件的其它示例。
如图19所示,第一触件1401a可与晶体管1408电连通,触件1401b-1401e可与微控制器1500电连通,并且第六触件1401f可与地电连通。在某些情况下,电触件1401b-1401e中的一个或多个电触件可与微控制器1500的一个或多个输出通道电连通,并且在柄部1042处于加电状态时可通电,或具有施加到其的电压电位。在一些情况下,电触件1401b-1401e中的一个或多个电触件可与微控制器1500的一个或多个输入通道电连通,并且当柄部组件14处于加电状态时,微控制器1500可被构造成能够检测电压电位何时被施加到此类电触件。当轴组件诸如轴组件200装配到柄部组件14时,电触件1401a-1401f可不彼此连通。然而,当轴组件未装配到柄部组件14时,电连接器1400的电触件1401a-1401f可暴露,并且在一些情况下,触件1401a-1401f中的一个或多个触件可意外地布置成彼此电连通。例如,当触件1401a-1401f中的一个或多个触件接触导电材料时,可出现此类情况。例如,当发生这种情况时,微控制器1500可接收错误的输入并且/或者轴组件200可接收错误的输出。为解决这个问题,在各种情况下,当轴组件诸如轴组件200未附接到柄部组件14时,柄部组件14可不加电。
在其它情况下,当轴组件诸如轴组件200未附接到柄部1042时,柄部1042可加电。在这种情况下,例如,微控制器1500可被构造成能够忽略不计施加到与微控制器1500电连通的触件(即,触件1401b-1401e)的输入或电压电位,直到轴组件附接到柄部组件14。即使在这种情况下微控制器1500可供应有功率,以操作柄部组件14的其它功能,该柄部组件14也可处于掉电状态。在某种程度上,电连接器1400可处于掉电状态,因为施加到电触件4001b-4001e的电压电位可能不影响柄部组件14的操作。读者将会知道,即使触件1401b-1401e可处于掉电状态,但未与微控制器1500电连通的电触件1401a和1401f可处于或可不处于掉电状态。例如,无论柄部组件14是处于加电还是掉电状态,第六触件4001f可保持与地电连通。
此外,无论柄部组件14是处于加电还是掉电状态,晶体管1408和/或任何其它合适布置的晶体管诸如晶体管1410和/或开关可被构造成能够控制从电源1404(例如,位于柄部组件14内的电池90)到第一电触件1401a的功率供应。在各种情况下,例如,当轴组件200与柄部组件14接合时,轴组件200可被构造成能够改变晶体管1408的状态。在某些情况下,除下述之外,磁场传感器1402可被构造成能够切换晶体管1410的状态,因此可切换晶体管1408的状态,最终将来自电源1404的功率供应给第一触件1401a。这样,联接到连接器1400的功率电路和信号电路两者在轴组件未安装到柄部组件14时可被掉电,而在轴组件安装到柄部组件14时可被加电。
在各种情况下,再次参见图19,柄部组件14可包括例如磁场传感器1402,该磁场传感器可被构造成能够在轴组件联接到柄部组件14时检测轴组件诸如轴组件200上的可检测元件诸如磁性元件1407(图3)。磁场传感器1402可由诸如电池之类的电源1406供电,该电源实际上可放大磁场传感器1402的检测信号,并经由图19所示的电路与微控制器1500的输入通道通信。一旦微控制器1500接收到指示轴组件已至少部分地联接到柄部组件14并因此电触件1401a-1401f不再暴露的输入,微控制器1500就可进入其正常的或加电的操作状态。在此类工作状态中,微控制器1500将对从轴组件传输到一个或多个触件1401b-1401e的信号进行评估,和/或通过处于其正常使用状态的一个或多个触件1401b-1401e将信号传输到轴组件。在各种情况下,在磁场传感器1402可检测到磁性元件1407之前,可能必须使轴组件200完全坐置。例如,虽然可利用磁场传感器1402来检测轴组件200是否存在,但也可利用任何合适系统的传感器和/或开关来检测轴组件是否已装配到柄部组件14。这样,除上述之外,联接到连接器1400的功率电路和信号电路两者在轴组件未安装到柄部组件14时可被掉电,而在轴组件安装到柄部组件14时可被加电。
在各种示例中,例如,如在本公开通篇中所使用,可采用任何合适的磁场传感器来检测轴组件是否已装配到柄部组件14。例如,用于磁场感测的技术包括霍尔效应传感器、探测线圈、磁通门、光泵、核旋、超导量子干涉仪(SQUID)、霍尔效应、各向异性磁电阻、巨磁电阻、磁性隧道结、巨磁阻抗、磁致伸缩/压电复合材料、磁敏二极管、磁敏晶体管、光纤、磁光,以及基于微机电系统的磁传感器等。
参见图19,微控制器1500通常可包括微处理器(“处理器”)和可操作地联接到该处理器的一个或多个存储器单元。处理器通过执行存储器中存储的指令码,可控制外科器械的各种部件,例如,马达、各种驱动系统和/或用户显示器。微控制器1500可使用集成和/或离散硬件元件、软件元件和/或硬件元件和软件元件两者的组合来实施。集成硬件元件的示例可包括处理器、微处理器、微控制器、集成电路、专用集成电路(ASIC)、可编程逻辑器件(PLD)、数字信号处理器(DSP)、现场可编程门阵列(FPGA)、逻辑门、寄存器、半导体器件、芯片、微芯片、芯片组、微控制器、片上系统(SoC)和/或封装系统(SIP)。离散硬件元件的示例可包括电路和/或电路元件,例如逻辑门、场效应晶体管、双极型晶体管、电阻器、电容器、电感器和/或继电器。在某些实例中,例如,微控制器1500可包括混合电路,该混合电路在一个或多个基板上包括离散和集成电路元件或部件。
参见图19,微控制器1500可为例如可购自Texas Instruments的LM 4F230H5QR。在某些实例中,Texas Instruments LM4F230H5QR为ARM Cortex-M4F处理器芯,其包括:256KB的单循环闪速存储器或其它非易失性存储器(最多至40MHZ)的片上存储器、用于使性能改善超过40MHz的预取缓冲器、32KB的单循环串行随机访问存储器(SRAM)、装载有软件的内部只读存储器(ROM)、2KB电可擦编程只读存储器(EEPROM)、一个或多个脉宽调制(PWM)模块、一个或多个正交编码器输入(QEI)模拟、具有12个模拟输入通道的一个或多个12位模数转换器(ADC),以及易得的其它特征。可以很方便地换用其他微控制器,来与本公开联合使用。因此,本公开不应限于这一上下文。
如上文所讨论,当轴组件200未装配到或未完全装配到柄部组件14时,柄部组件14和/或轴组件200可包括被构造成能够防止或至少降低柄部电连接器1400的触件和/或轴电连接器1410的触件发生短路的可能性的系统和构型。参见图3,柄部电连接器1400可至少部分地凹陷于限定于柄部框架20中的腔体1409内。电连接器1400的六个触件1401a-1401f可完全陷入腔体1409内。这种布置可降低物体意外地接触触件1401a-1401f中的一个或多个触件的可能性。相似地,轴电连接器1410可定位在轴底座240中限定的凹陷部内,这可降低物体意外地接触轴电连接器1410的触件1411a-1411f中的一个或多个触件的可能性。参照图3所示的具体示例,轴触件1411a-1411f可包括凸形触件。在至少一个示例中,例如,每个轴触件1411a-1411f可包括从其延伸的柔性突出部,该柔性突出部可被构造成能够接合对应的柄部触件1401a-1401f。柄部触件1401a-1401f可包括凹形触件。在至少一个示例中,每个柄部触件1401a-1401f可包括例如平坦表面,轴凸形触件1401a-1401f可贴靠该平坦表面擦过或滑过,并且维持平坦表面和轴凸形触件1401a-1401f之间的导电接合。在各种实例中,将轴组件200装配到柄部组件14的方向可平行于或至少基本上平行于柄部触件1401a-1401f,使得当将轴组件200装配到柄部组件14时,轴触件1411a-1411f贴靠柄部触件1401a-1401f滑动。在各种另选示例中,柄部触件1401a-1401f可包括凸形触件,并且轴触件1411a-1411f可包括凹形触件。在某些另选示例中,柄部触件1401a-1401f和轴触件1411a-1411f可包括任何合适布置的触件。
在各种实例中,柄部组件14可包括被构造成能够至少部分地覆盖柄部电连接器1400的连接器防护件和/或被构造成能够至少部分地覆盖轴电连接器1410的连接器防护件。当轴组件未装配到、或只是部分地装配到柄部时,连接器防护件可防止、或至少降低物体意外地接触电连接器的触件的可能性。连接器防护件可以是可动的。例如,连接器防护件可在防护位置与非防护位置之间运动,在防护位置,该连接器防护件至少部分地保护连接器,在非防护位置,该连接器防护件不保护连接器,或至少为连接器提供较少保护。在至少一个示例中,连接器防护件的位置可随着轴组件装配到柄部而移位。例如,如果柄部包括柄部连接器防护件,则轴组件可随着轴组件装配到柄部而接触并移位柄部连接器防护件。相似地,如果轴组件包括轴连接器防护件,则柄部可随着轴组件装配到柄部而接触并移位轴连接器防护件。在各种实例中,例如,连接器防护件可包括门。在至少一种情况下,该门可包括倾斜表面,当门与柄部或轴接触时,该倾斜表面可有利于门沿一定方向的移位。在各种实例中,例如,连接器防护件可被平移和/或旋转。在某些实例中,连接器防护件可包括覆盖电连接器触件的至少一层膜。当轴组件装配到柄部时,该层膜可能破裂。在至少一个实例中,连接器的凸形触件可先刺透这层膜,再与定位在这层膜下方的对应触件接合。
如上所述,外科器械可包括能够选择性地使电连接器诸如电连接器1400的触件加电或激活的系统。在各种实例中,触件可在未激活状况和激活状况之间转换。在某些实例中,触件可在监控状况、去激活状况和激活状况之间转换。例如,当轴组件尚未装配到柄部组件14时,微控制器1500例如可监控触件1401a-1401f,以确定触件1401a-1401f中的一个或多个触件是否可能已经短路。微控制器1500可被构造成能够将低电压电位施加到触件1401a-1401f中的每个触件,并评估在该触件中的每个触件处是否仅存在最小电阻。这种操作状态可包括监控状况。如果在某个触件处检测到的电阻很高,或超过了阈值电阻,则微控制器1500可去激活该触件、多于一个触件,或者全部触件。这种操作状态可包括去激活状况。如上文所讨论,如果轴组件装配到柄部组件14,并被微控制器1500检测到,则微控制器1500可提高施加到触件1401a-1401f的电压电位。这种操作状态可包括激活状况。
本文所公开的各种轴组件可采用传感器和各种其他部件,所述传感器和各种其他部件需要与外壳中的控制器电连通。这些轴组件通常被构造成能够相对于外壳旋转,因此必须在两个或更多个可相对彼此旋转的部件之间设置有利于这种电连通的连接件。当采用本文所公开类型的端部执行器时,连接器构造在本质上必须相对稳固,同时还必须略微紧凑,以装配到轴组件的连接器部分中。
参见图20,示出了端部执行器300的非限制性形式。如上所述,端部执行器300可包括砧座306和钉仓304。在该非限制性示例中,砧座306联接到细长通道198。例如,开孔199可限定于细长通道198中,这些开孔可接收从砧座306延伸的销152并允许砧座306相对于细长通道198和钉仓304从打开位置枢转到闭合位置。此外,图20示出了被构造成能够纵向平移到端部执行器300中的击发杆172。击发杆172可由一个实心节段构成,或在各种示例中,可包括层压材料,该层压材料包括例如一叠钢板。击发杆172的远侧突出端可附接到E形梁178,该E形梁可(除了其它以外)在砧座306处于闭合位置时有助于将砧座306与定位在细长通道198中的钉仓304间隔开。E形梁178还可包括锋利切割刃182,当通过击发杆172向远侧推进E形梁178时,切割刃182可用于切断组织。在操作中,E形梁178还可致动或击发钉仓304。钉仓304可包括模塑的仓体194,该仓体保持多个钉191,所述多个钉安置在钉驱动器192上,所述钉驱动器位于相应的向上打开的钉腔195内。楔形滑动件190通过E形梁178朝远侧驱动,从而在仓托盘196上滑动,该仓托盘将可替换钉仓304的各种部件保持在一起。楔形滑动件190使钉驱动器192向上进行凸轮运动,以将钉191挤出成与砧座306变形接触,同时E形梁178的切割表面182切断夹持的组织。
除上述之外,E形梁178可包括在击发期间接合砧座306的上部销180。E形梁178还可包括中间销184和底脚186,其可接合仓体194、仓托盘196和细长通道198的各个部分。当钉仓304定位在细长通道198内时,限定于仓体194中的狭槽193可与限定于仓托盘196中的狭槽197以及限定于细长通道198中的狭槽189对齐。在使用中,E形梁178可滑动穿过对齐的狭槽193、197和189,如图20所示,其中E形梁178的底脚186可沿着狭槽189的长度接合沿着通道198的底面延伸的沟槽,中间销184可沿着纵向狭槽197的长度接合仓托盘196的顶部表面,并且上部销180可接合砧座306。在这种情况下,当击发杆172向远侧运动以从钉仓304击发钉和/或切入砧座306和钉仓304之间捕集的组织时,E形梁178可隔开或限制砧座306和钉仓304之间的相对运动。然后,击发杆172和E形梁178可向近侧回缩,从而允许砧座306打开,以释放两个缝合和切断的组织部分(未示出)。

在一个方面,安全处理器2004被构造成能够针对一个或多个电路段2002c-2002h(例如,马达段2002g)实施看门狗功能。就这一点来说,安全处理器2004采用看门狗功能来检测主处理器2006的故障并从主处理器2006的故障中恢复。在正常操作期间,安全处理器2004监控主处理器2004的硬件故障或程序错误,并发起一种或多种校正动作。校正动作可包括将主处理器2006置于安全状态,并恢复正常的系统操作。在一个示例中,安全处理器2004至少联接到第一传感器。第一传感器测量外科器械10(图1至图4)的第一性质。在一些示例中,安全处理器2004被构造成能够将外科器械10的所测量性质与预先确定的值进行比较。例如,在一个示例中,马达传感器2040a联接到安全处理器2004。马达传感器2040a向安全处理器2004提供马达的速度和位置信息。安全处理器2004监控马达传感器2040a并将值与最大速度和/或位置值进行比较,并且如果值高于预先确定的值,则阻止马达2048的操作。在一些示例中,预先确定的值基于马达2048的实时速度和/或位置计算、从与主处理器2006连通的第二马达传感器2040b提供的值计算,并且/或者从例如联接到安全处理器2004的存储器模块提供给安全处理器2004。
在一些方面,第二传感器联接到主处理器2006。第二传感器被构造成能够测量第一物理性质。安全处理器2004和主处理器2006被构造成能够提供分别指示第一传感器的值和第二传感器的值的信号。当安全处理器2004或主处理器2006指示值超出可接受范围时,分段电路2000便阻止电路段2002c-2002h中的至少一个电路段诸如例如马达段2002g的操作。例如,在图21A至图21B所示的示例中,安全处理器2004联接到第一马达位置传感器2040a,并且主处理器2006联接到第二马达位置传感器2040b。马达位置传感器2040a、2040b可包括任何合适的马达位置传感器,例如,具有正弦和余弦输出的磁性角度旋转输入装置。马达位置传感器2040a、2040b向安全处理器2004和主处理器2006提供指示马达2048的位置的相应的信号。
当第一马达传感器2040a的值和第二马达传感器2040b的值处于预先确定的范围内时,安全处理器2004和主处理器2006生成激活信号。当主处理器2006或安全处理器2004检测到值超出预先确定的范围时,则终止激活信号,随即中断并/或阻止至少一个电路段2002c-2002h(例如,马达段2002g)的操作。例如,在一些示例中,来自主处理器2006的激活信号和来自安全处理器2004的激活信号联接到与门。与门联接到马达功率开关2020。当来自安全处理器2004和主处理器2006两者的激活信号都较高(指示马达传感器2040a,2040b的值在预先确定的范围内)时,与门便将马达功率开关2020保持在闭合或打开位置。当马达传感器2040a,2040b中任一者检测到值超出预先确定的范围时,则来自马达传感器2040a,2040b的激活信号被设定为低,并且与门的输出也被设定为低,从而打开马达功率开关2020。在一些示例中,第一传感器2040a的值与第二传感器2040b的值例如通过安全处理器2004和/或主处理器2006进行比较。当第一传感器的值与第二传感器的值不同时,安全处理器2004和/或主处理器2006便可阻止马达段2002g的操作。
在一些方面,安全处理器2004接收指示第二传感器2040b的值的信号,并且将第二传感器的值与第一传感器的值进行比较。例如,在一个方面,安全处理器2004直接联接到第一马达传感器2040a。第二马达传感器2040b联接到主处理器2006和/或直接联接到安全处理器2004,该主处理器将第二马达传感器2040b的值提供给安全处理器2004。安全处理器2004将第一马达传感器2040的值与第二马达传感器2040b的值进行比较。当安全处理器2004检测到第一马达传感器2040a与第二马达传感器2040b之间存在失配时,安全处理器2004可例如通过切断到马达段2002g的功率来中断马达段2002g的操作。
在一些方面,安全处理器2004和/或主处理器2006联接到被构造成能够测量外科器械的第一性质的第一传感器2040a和被构造成能够测量外科器械的第二性质的第二传感器2040b。第一性质和第二性质包括外科器械正常操作时的预先确定的关系。安全处理器2004监控第一性质和第二性质。当检测到第一性质的值和/或第二性质的值与预先确定的关系不一致时,则发生故障。当发生故障时,安全处理器2004至少采取一种动作,例如,阻止电路段中的至少一个的操作、执行预先确定的操作,和/或重置主处理器2006。例如,安全处理器2004在检测到故障时可打开马达功率开关2020,以切断到马达电路段2002g的功率。
在一个方面,安全处理器2004被构造成能够执行独立的控制算法。在操作中,安全处理器2004监控分段电路2000并且被构造成能够独立地控制和/或覆写来自其它电路部件诸如例如主处理器2006的信号。安全处理器2004可执行预先编程的算法并且/或者在操作期间可基于外科器械10的一种或多种动作和/或位置实时更新或编程。例如,在一个示例中,每当新的轴和/或端部执行器联接到外科器械10时,便使用新的参数和/或安全算法对安全处理器2004进行重新编程。在一些示例中,安全处理器2004存储的一个或多个安全值由主处理器2006复制。执行双向错误检测,以确保处理器2004或2006存储的值和/或参数是正确的。
在一些方面,安全处理器2004和主处理器2006实施冗余的安全检查。安全处理器2004和主处理器2006提供指示正常操作的周期性信号。例如,在操作期间,安全处理器2004可向主处理器2006指示安全处理器2004正在执行代码并且正常操作。主处理器2006同样可向安全处理器2004指示主处理器2006正在执行代码并且正常操作。在一些示例中,安全处理器2004和主处理器2006之间的连通是以预先确定的间隔发生的。预先确定的间隔可为恒定的,也可基于外科器械10的电路状态和/或操作而变化。

在一些实例中,使用循环电路2102被构造成能够监控功率组件2100所历经的修复循环次数。修复循环可包括例如清洁循环、消毒循环、充电循环、常规和/或预防维修、和/或任何其他合适的修复循环。使用指示器2106被构造成能够检测修复循环。例如,使用指示器2106可包括水分传感器以检测清洁和/或消毒循环。在一些实例中,使用循环电路2102监控功率组件2100所历经的修复循环次数,并在修复循环次数超出预先确定的阈值之后,停用功率组件2100。
使用循环电路2102可被构造成能够监控功率组件2100交换的次数。每当交换功率组件2100时,使用循环电路2102便递增使用循环计数。当超出最大交换次数时,使用循环电路2102锁定功率组件2100和/或外科器械2110。在一些实例中,当功率组件2100联接到外科器械2110时,使用循环电路2102识别功率组件2100的序列号并锁定功率组件2100,使得功率组件2100只能与外科器械2110一起使用。在一些实例中,每当功率组件2100从外科器械2110移除和/或联接到该外科器械时,使用循环电路2102递增使用循环。
在一些实例中,使用循环计数对应于功率组件2100的消毒。使用指示器2106包括被构造成能够检测消毒循环的一个或多个参数诸如例如温度参数、化学参数、水分参数和/或任何其它合适的参数的传感器。当检测到消毒参数时,处理器2104递增使用循环计数。在预先确定的消毒次数之后,使用循环电路2102停用功率组件2100。在一些实例中,使用循环电路2102在消毒循环、电压传感器和/或任何合适的传感器检测再充电循环期间被重置。当检测到修复循环时,处理器2104递增使用循环计数。当检测到消毒循环时,停用使用循环电路2102。当功率组件2100联接到外科器械2110时,重新激活和/或重置使用循环电路2102。在一些实例中,使用指示器包括零功率指示器。零功率指示器在消毒循环期间改变状态,并当功率组件2100联接到外科器械2110时由处理器2104检查。当零功率指示器指示已经发生消毒循环时,处理器2104递增使用循环计数。
计数器2108保持着使用循环计数。在一些实例中,计数器2108包括非易失性存储器模块。每当检测到使用循环时,处理器2104便递增存储在非易失性存储器模块中的使用循环计数。存储器模块可由处理器2104和/或控制电路诸如例如控制电路200访问。当使用循环计数超出预先确定的阈值时,处理器2104停用功率组件2100。在一些实例中,使用循环计数由多个电路部件保持。例如,在一个实例中,计数器2108包括电阻器(或熔断器)组。在每次使用功率组件2100之后,电阻器(或熔断器)可被烧断成打开位置,从而改变电阻器组的电阻。功率组件2100和/或外科器械2110读取剩余的电阻值。当电阻器组的最后一个电阻器被烧坏时,电阻器组便具有预先确定的电阻诸如例如,对应于开式电路的无穷大电阻,这表明功率组件2100已经达到其使用限度。在一些实例中,电阻器组的电阻用于推导出剩余的使用次数。
在一些实例中,当使用循环计数超出预定使用限度时,使用循环电路2102便阻止功率组件2100和/或外科器械2110的进一步使用。在一个实例中,例如,利用与外科器械2110一体形成的屏幕将与功率组件2100相关的使用循环计数提供给操作者。外科器械2110向操作者提供使用循环计数已经超出功率组件2100的预先确定的限值的指示,并阻止外科器械2110的进一步操作。
在一些实例中,使用循环电路2102被构造成能够在达到预先确定的使用限度时在物理上防止其操作。例如,功率组件2100可包括护罩,该护罩被构造成能够在使用循环计数超出预先确定的使用限度时部署在功率组件2100的触件上。该护罩通过覆盖功率组件2100的电连接件阻止功率组件2100的再充电及使用。
在一些实例中,使用循环电路2102至少部分地位于外科器械2110内,并被构造成能够保持外科器械2110的使用循环计数。图22以虚线示出了外科器械2110内的使用循环电路2102的一个或多个部件,并示出使用循环电路2102的另选定位。当超出外科器械2110的预先确定的使用限度时,使用循环电路2102停用和/或阻止外科器械2110的操作。当使用指示器2106检测到特定事件和/或需求(例如,外科器械2110的击发、对应于单次患者手术时间的预先确定的时间段)时,使用循环电路2102响应于表明达到了一个或多个预先确定的阈值和/或满足了任何其它合适需求的系统诊断,而根据外科器械2110的一个或多个马达参数递增使用循环计数。如上文所讨论,在一些实例中,使用指示器2106包括对应于单次患者手术时间的计时电路。在其它实例中,使用指示器2106包括一个或多个传感器,这些传感器被构造成能够检测外科器械2110的特定事件和/或条件。
在一些实例中,使用循环电路2102被构造成能够防止在达到预先确定的使用限度之后使用外科器械2110。在一些实例中,外科器械2110包括可视指示器,以便当已经达到和/或超过预先确定的使用限度时给出指示。例如,标记(例如红色标记)可从外科器械2110(例如从柄部)弹出,从而为操作者提供外科器械2110已超出预先确定的使用限度的视觉指示。又如,使用循环电路2102可联接到与外科器械2110一体形成的显示器。使用循环电路2102显示指示已经超出预先确定的使用限度的信息。外科器械2110可以向操作者提供已经超出预先确定的使用限度的听觉指示。例如,在一个实例中,当超出预先确定的使用限度时,外科器械2110发出可以听见的音调,然后将功率组件2100从外科器械2110移除。可以听见的音调指示外科器械2110的最后一次使用,并指示应该丢弃或修复外科器械2110。
在一些实例中,使用循环电路2102被构造成能够将外科器械2110的使用循环计数传输到远程位置,例如,中央数据库。使用循环电路2102包括被构造成能够将使用循环计数传输到远程位置的通信模块2112。通信模块2112可利用任何合适的通信系统,例如,有线和/或无线通信系统。远程位置可包括被构造成能够保持使用信息的中央数据库。在一些实例中,当功率组件2100联接到外科器械2110时,功率组件2100记录外科器械2110的序列号。例如,当功率组件2100联接到充电器时,该序列号被传输到中央数据库。在一些实例中,中央数据库保持着对应于外科器械2110的每一次使用的计数。例如,每次使用外科器械2110时,与外科器械2110相关联的条形码便可被扫描。当使用计数超过预先确定的使用限度时,中央数据库向外科器械2110提供指示应该丢弃外科器械2110的信号。
外科器械2110可被构造成能够在使用循环计数超出预先确定的使用限度时锁定和/或阻止操作外科器械2110。在一些实例中,外科器械2110包括一次性仪器,并且在使用循环计数超出预先确定的使用限度之后被丢弃。在其它实例中,外科器械2110包括可重复使用的外科器械,该外科器械可在使用循环计数超出预先确定的使用限度之后被修复。在达到预先确定的使用限度之后,外科器械2110引发可逆闭锁。技术人员例如利用被构造成能够重置使用循环电路2102的专业技术键来修复外科器械2110并释放闭锁。

图28A和图28B示出了控制电路3000的另一方面,该控制电路被构造成能够控制图1至图18A所示的电动外科器械10。如图18A、图28B所示,柄部组件14可包括马达3014,该马达可由马达驱动器3015控制,并可由外科器械10的击发系统使用。在各种形式中,马达3014可以是直流有刷驱动马达,其具有例如大约25,000RPM的最大转速。在其它布置中,马达3014可包括无刷马达、无绳马达、同步马达、步进马达或任何其它合适的电动马达。在某些情况下,马达驱动器3015可包括例如H桥FET 3019,如图28A和图28B所示。马达3014可由功率组件3006供电,该功率组件能够可释放地安装到柄部组件14。功率组件3006被构造成能够向外科器械10供应控制功率。功率组件3006可包括电池,该电池可包括串联连接的多个电池单元,该多个电池单元可用作电源,以对外科器械10供电。在这种构型中,功率组件3006可称为电池组。在某些情况下,功率组件3006的电池单元可以是可替换的和/或可充电的。在至少一个示例中,电池单元可以是能够可分离地联接到功率组件3006的锂离子电池。
适合与外科器械10一起使用的驱动系统和闭合系统的示例公开于名称为“CONTROL SYSTEM OF A SURGICAL INSTRUMENT”且提交于2013年3月14日的美国临时专利申请序列号61/782,866,该专利的完整公开内容全文以引用方式并入本文。例如,电动马达3014可包括与齿轮减速器组件可操作地连接的可旋转轴(未示出),该齿轮减速器组件可被安装成与能够纵向运动的驱动构件上的一组或一齿条的驱动齿啮合接合。在使用中,电池所提供的电压极性可操作电动马达3014,以驱动能够纵向运动的驱动构件,以使端部执行器300起作用。例如,马达3014可被构造成能够驱动能够纵向运动的驱动构件,例如,以推进击发机构,从而将钉从与端部执行器300装配在一起的钉仓击发到由端部执行器300捕集的组织中,并且/或者推进切割构件,从而切割由端部执行器300捕集的组织。
如图28A和图28B所示,并如下文更详细地描述,例如,功率组件3006可包括功率管理控制器,该功率管理控制器可被构造成能够调节功率组件3006的功率输出,以便当可互换轴组件200联接到柄部组件14(图1)时,输送第一功率输出来为马达3014供电,以推进切割构件,而当可互换轴组件200联接到柄部组件14时,输送第二功率输出来为马达3014供电,以推进切割构件。这种调节在避免将超出联接到柄部组件14的可互换轴组件需求的过高功率传输到马达3014这方面可以是有利的。
在某些情况下,例如,通过将一个或多个通信信号路由通过位于柄部组件14(图1)中的主控制器3017,接口3024可有利于在功率管理控制器3016与轴组件控制器3022之间传输这类通信信号。在其他情况下,当轴组件200(图1)和功率组件3006联接到柄部组件14时,接口3024可有利于通过柄部组件14的功率管理控制器3016和轴组件控制器3022之间的直接通信线路。
在一个实例中,主微控制器3017可以是任一种单核或多核处理器,例如由TexasInstruments提供的以ARM Cortex为商品名的那些。在一个实例中,外科器械10(图1至图4)可包括功率管理控制器3016,例如,包括两个基于微控制器的系列(例如同样由TexasInstruments提供的以Hercules ARM Cortex R4为商品名的TMS570和RM4x)的安全微控制器平台。然而,可不受限制地采用微控制器和安全处理器的其他合适的替代物。在一个实例中,安全处理器2004(图21A)可专门构造用于IEC 61508和ISO 26262安全关键应用等,以在输送可扩展的性能、连接性和存储器选项时提供高级集成安全特征。
在某些实例中,微控制器3017可以是例如可购自Texas Instruments的LM4F230H5QR。在至少一个示例中,Texas Instruments LM4F230H5QR是ARM Cortex-M4F处理器内核包括高达40MHz的256KB单周期闪速存储器或其它非易失性存储器的芯片上存储器、40MHz以上的用于提高性能的预取缓冲区、32KB单周期串行随机存取存储器(SRAM)、加载有软件的内置只读存储器(ROM)、2KB电可擦除可编程只读存储器(EEPROM)、一个或多个脉宽调制(PWM)模块、一个或多个正交编码器输入(QEI)模拟、具有12个模拟输入通道的一个或多个12位模/数转换器(ADC)、以及随时可用于产品数据表的其它特征。本公开不应限于这一上下文。

值得注意的是,功率管理控制器3016和/或轴组件控制器3022各自可包括可存储多个软件模块的一个或多个处理器和/或存储器单元。尽管可以举例的方式描述外科器械14(图1)的某些模块和/或块,但可以理解,可使用更多或更少数量的模块和/或块。另外,虽然可根据模块和/或块来描述各种实例以有利于说明,但这些模块和/或块可通过一个或多个硬件部件(如处理器、数字信号处理器(DSP)、可编程逻辑装置(PLD)、专用集成电路(ASIC)、电路、寄存器)和/或软件部件(如程序、子例程、逻辑)、和/或硬件部件与软件部件的组合来实施。
在某些实例中,外科器械10(图1至图4)可包括输出装置3042,该输出装置可包括用于向用户提供感官反馈的一个或多个装置。此类装置可包括例如视觉反馈装置(例如,LCD显示屏、LED指示器)、听觉反馈装置(例如,扬声器、蜂鸣器)或触觉反馈装置(例如,触觉致动器)。在某些情况下,输出装置3042可包括显示器3043,该显示器可包括在柄部组件14(图1)中。轴组件控制器3022和/或功率管理控制器3016可通过输出装置3042向外科器械10的用户提供反馈。接口3024可被构造成能够将轴组件控制器3022和/或功率管理控制器3016连接到输出装置3042。读者将会知道,作为替代,输出装置3042可与功率组件3006集成。在这类情况下,当轴组件200联接到柄部组件14时,输出装置3042与轴组件控制器3022之间的通信可通过接口3024来实现。
在已描述外科器械10(图1-4)和用于控制其操作的各种控制电路2000、3000的前提下,本公开现转到外科器械10和控制电路2000(或3000)的各种具体构型。
本公开还提供了用于模块化再加载件的新型技术,以识别自身并且限定马达控制器的操作程序来致动模块。
一种技术包括定义程序表并且构造模块以将所要选择和执行的软件程序(或其他机器可执行的指令)传送到柄部。作为对比,可设想到其他技术,所述技术在内镜外科装置的柄部部分中不包括操作程序,相反将程序存储在模块自身中,并且在附接柄部时上载程序来执行。在另一种技术中,将不在柄部中执行任何程序。柄部将包含马达控制器、致动按钮和甚至功率控制器,但不包括操作程序。模块将包含全部上层逻辑器和子处理器以执行程序,使得每个模块包括主处理器和该再加载件的程序。当轴附接到柄部时,处理器通电并且其识别所附接的柄部。一旦被识别,柄部就从属于具有给定和处理全部命令的模块的模块化再加载件。当按钮被按下时,例如,模块作出响应并且确定下一个动作,然后将运动的距离和速度以及停止的时间传送给从马达控制器。如果在模块中包括主处理器,则还应在模块与柄部之间存在相对较高带宽的通信总线以允许必要的通信流量。这可通过以下方式来实现:将模块化附接件的旋转轴部件保持在站框架附接部件内,使得固定部分容纳处理器和控制程序。因此,通信总线不必还用作滑环触点组。
如本文所述,外科系统可包括模块化部件,该模块化部件可附接和/或结合在一起而形成外科器械。此类模块化部件可被构造成能够通信和相互作用以影响外科功能。再次参见外科器械10(图1-4),外科器械10包括第一模块化部件14(图1)(例如,柄部组件14)和第二模块化部件200(图1),例如,包括本文所述的细长轴260(图1)和端部执行器300(图1)的附接组件。柄部组件14和附接组件200可组装在一起以形成模块化外科器械10或其至少一部分。任选地,不同的模块化部件可联接到柄部组件14,诸如具有不同于附接组件200(图1)的尺寸和/或特征结构的附接件。例如,另选的附接件可与附接组件200互换。在各种情况下,外科器械10可包括另外的模块化部件,例如诸如模块化电池90(图4)。

在其他情况下,外科器械10(图1-4)的处理器可包括主处理器,并且外科器械10的另一个处理器可包括从处理器。操作系统和/或多个控制模块可被主处理器访问。例如,操作系统和/或控制模块可利用和/或通过例如外科器械10的元件或子系统来影响至少一个外科功能。控制模块可包括例如软件、固件、程序、模块和/或例程,并且/或者可包括例如多个软件、固件、程序、控制模块和/或例程。控制模块可基于例如预先编制的例程、操作者输入和/或系统反馈来影响外科功能。在各种情况下,主处理器可被构造成能够将信息和/或命令引导到从处理器。此外,从处理器可被构造成能够从主处理器接收信息和/或命令。从处理器可响应于来自主处理器的命令来起作用。在各种情况下,从处理器可不包括控制模块和/或操作系统,并且从处理器的动作可归因于来自主处理器和可被主处理器访问的控制模块的命令。如本文所述,外科器械10的附接组件200(图1)的控制系统可包括主处理器,并且外科器械10的柄部组件14(图1)的控制系统可包括例如至少一个从处理器。
再次参见外科器械10(图1-4),柄部组件14可与不同的附接件兼容,所述附接件可被构造成能够影响不同的外科功能。各种附接件可为可互换的,并且不同的外科功能可对应于例如不同的组织类型和/或不同的外科手术。因为不同的附接件可被构造成能够影响不同的外科功能,所以专用于特定附接件的控制模块可存储在相应的附接件上。例如,附接组件200(图1)可存储专用的控制模块以用于操作附接组件200。另外,附接组件200可包括上层逻辑器和子处理器以运行控制模块。在此类情况下,附接组件200中的处理器可包括主控制系统和/或主处理器,所述主控制系统和/或主处理器被构造成能够命令柄部组件14中的从处理器以执行存储在附接组件200上的控制模块。
因为每个附接件包括用于其操作的专用控制模块,并且因为附接件中的处理器包括主处理器,所以模块化外科器械10被构造成能够针对特定的附接件运行最适当的和最新的控制模块。另外,当更新的和/或修改的附接件和/或其控制模块被设计和应用时,更新的和/或修改的附接件被设计成能够与具有并非最新更新和/或修改的柄部组件一起适当地工作。换句话讲,更新的和/或修改的附接件可翻新以与现有和/或旧式柄部组件一起适当地操作。

在各种情况下,当附接组件200(图1)附接到柄部组件14(图1)时,电连接器1400(图3)、1410(图3)可接合,并且柄部组件14中的电池90(图4)可对柄部组件14和附接组件200供电。例如,当附接组件200联接到柄部组件14时,电池90可对轴电路板610(图7)提供电力。在各种情况下,当附接组件200连接到柄部组件14时,电池90可对轴电路板610和/或其部件自动地供电。
