无线夹计数器
相关申请的交叉引用
本申请要求于2009年10月6日提交的、序列号为61/248,944的美国临时申请的优先权和利益，将其整个内容通过引用并入在此。
技术领域
本申请涉及外科器械，更特别地，涉及一种外科施夹器，其具有发送器(transmitter)和远程显示器以计数所述外科施夹器中夹子的数目。
背景技术
外科施夹器是现有技术已知的，并由于向体组织和血管的传统缝合提供了另一种选择而得到更多外科医生的欢迎。美国专利No.5,030,226(Green等人)和美国专利No.5,431,668(Burbank III等人)公开了典型的器械。这些器械通常提供多个夹子，所述多个夹子存储在器械中并基于器械近端处手柄的开合而被相继送入器械远端处的钳夹机构。当手柄闭合时，钳夹闭合以使位于钳夹元件之间的夹子变形，而当钳夹张开以释放变形的夹子时，将一个新的夹子从其序列送入钳夹之间的位置。这个过程重复执行直到将夹子序列中的所有夹子都已用过。
现有技术中还已知内窥镜用施夹器用于在进入体腔的过程中施加单个夹子。这些单个施夹器典型地由生物相容性材料制成并通常压在血管上。一旦施加在血管上，被压缩的夹子就终止流体流过其中。在共同转让的美国专利No.5,084,057和No.5,100,420(Green等人)中描述了内窥镜用施夹器，所述内窥镜用施夹器在内窥镜或腹腔镜检查过程中，当单次进入体腔时能够施加多个夹子，将所述两个专利的全部内容通过引用并入。在共同转让的美国专利No.5,607,436(Pratt等人)中公开了另一种多个内窥镜用施夹器，据此也将其全部内容通过引用并入。虽然不是必须的，但是在单一外科手术过程中还是典型地使用这些设备。美国专利申请序列号No.08/515,341即现在的美国专利No.5,695,502(Pier等人)公开了一种可重新消毒的外科施夹器，据此将其公开内容通过引用并入在此。所述施夹器在单次插入体腔的过程中改善和成形多个夹子。
夹子的应用可能会由于位于设备近端的用户的视野减小或触觉反馈的减少而复杂化。因此，需要通过向用户提供装载单元中所含的夹子用完的指示来改善器械的操作。传统的外科施夹器或内窥镜用施夹器具有内置计数器和显示器来提供这样的指示。由于施夹器的尺寸，显示器的尺寸会相对小。

具体实施方式
现在将参照附图对依照本公开的外科施夹器的实施例进行详细描述，其中相同的附图标记代表类似或相同的结构元件。如附图所示以及如下贯穿全文所描述的，当涉及外科器械的相对位置时，跟传统的一样，术语“近侧”表示装置靠近用户的一端，而术语“远侧”表示装置远离用户的一端。
多种外科施夹器可与在此描述的实施例配合使用。在2009年3月18日提出的、序列号为No.12/406,345、题为“Endoscopic Surfical Clip Applier(内窥镜外科施夹器)”的美国专利申请；2008年8月25日提出的、序列号为No.61/091,485的美国临时专利申请；以及2008年8月29日提出的、序列号为No.61/092,804的美国临时专利申请中描述了这些施夹器，将所述专利的全部内容通过引用并入于此。
现在参见图1至6，依照本公开的实施例的外科施夹器通常用100表示。外科施夹器100通常包括手柄组件102，该手柄组件102包括具有上半外壳104a和下半外壳104b的外壳104。手柄组件102进一步包括一对手柄106，所述一对手柄106可枢转地固定在外壳104上并从此处向外延伸。通道组件108稳固地固定在外壳104上并从此处向外延伸，终止于钳夹组件110。
如图1至7所示，施夹器100的两半外壳104a和104b通过彼此搭扣配合(snap fit)接合而装在一起。外壳104限定了形成于下半外壳104b内的用于支撑计数器机构190的窗口104c，计数器机构190在下文将参考图17进行更详细讨论。外壳104由合适的塑性材料制成。
如在图4中可见，手柄106通过手柄枢轴支柱104d固定在外壳104上，支柱104d从下半外壳104b延伸出并进入到形成于手柄106上的相应的孔106a内。手柄组件102包括连杆元件122，该连杆元件122在形成于相应手柄106上的枢轴点106b处枢转地连接至每个手柄106。每个连杆元件122的远端122a通过驱动销124枢转地连接到形成于驱动通道140内的枢轴点140a。驱动销124的每端可滑动地容纳在形成于相应的上、下半外壳104a、104b内的细长通道104e中。使用时，如下文将更详细描述的，当扣动手柄106时，连杆元件122通过驱动销124向远侧推动驱动通道140。
通道组件108包括通道或仓盖130和外部或下部通道132，各自均具有保持在外壳组件102内并位于上、下半外壳104a、104b之间的近端。仓盖130包括至少一个保持构件130a，其被构造为并适于可选择地以搭扣配合接合的方式与设置在外部通道132上的互补或相应的保持构件132a相接合。
如在图4和6中可见，施夹器100包括可滑动地配置在仓盖130下方的夹子推杆(push bar)160。推杆160包括限定了推动器160c的远端160a，所述推动器160c被构造为并适于可选择地接合/移动存放在外科施夹器100内的最远侧夹子“C1”。推杆160进一步包括近端160b，近端160b限定了可滑动地接收驱动销124于其中的近侧窗口160d。推杆160还在其中限定了用于可操作地与稳定器162接合的远侧窗口160e，稳定器162在下文将更详细讨论。推杆160还包括从其侧边突出并相对来说紧挨近侧窗口160d的鳍状部160f。
施夹器100进一步包括稳定器162，所述稳定器162被构造为覆于推杆160之上并与其接合。稳定器162包括：远侧突起162a，所述突起162a被构造为接合推杆160的远侧窗口160e；以及细长窗口162b，其限定为位于基本覆于形成于推杆160的近侧窗口160d之上并与之对准。稳定器162进一步包括突块(nub)162c，突块162c从稳定器162底部表面延伸出，位于细长窗口162b的近侧，并被构造且定尺寸为容纳在形成于推杆160中的最近侧孔160g中。如在图4和6中可见，稳定器162进一步包括一对突起162e，它们从稳定器顶表面的延伸出，位于近侧和远侧位置，并被构造且定尺寸为容纳在形成于上半外壳104a中的相应通道中。
如在图4和4A至4C中可见，施夹器100进一步包括运动倍增系统，其具有枢转地支撑在外壳104内的钟形曲柄传动件154和可滑动地支撑在外壳104内的加速齿条156。钟形曲柄传动件154包括：枢轴销154a，其被构造为可枢转地连接到外壳104；支撑于枢轴销154a上的盘形体154b；从盘形体154b径向延伸出的臂154c；以及正齿轮154d，其支撑在枢轴销154a上或与之一体形成并邻近盘形体154b设置。钟形曲柄传动件154限定了形成于盘形体154b侧边的棘爪或凹口154e(见图4C)以及形成在臂154c中的纵向定位的槽154f。钟形曲柄传动件154的正齿轮154d限定了多个形成于其侧边的齿轮齿154g，并且可为正如图4C所示的扇形齿轮。
钟形曲柄传动件154对于每个小型、中型或大型施夹器100来说是通用部件。形成于钟形曲柄传动件154的盘形体154b侧边上的凹口154e可用于大型施夹器的组装。更大型的施夹器需要更大的推进器冲程，因此需要钟形曲柄传动件154旋转更大角度。由于钟形曲柄传动件154的更大的旋转，盘形体154b将接触从加速齿条156延伸出的突起156e(见图4A和4B)。在组装过程中，使钟形曲柄传动件154旋转直到凹口154e接触加速齿条156的突起156e。
继续参见图4和4A至4C，运动倍增系统的加速齿条156包括基座壁156a，基座壁156a限定了形成于其中的细长的、纵向延伸的槽156b，用于可滑动地接收钟形曲柄传动件154的枢轴销154a。加速齿条156包括从基座壁156a侧边沿相反的两方向突出的侧壁156c，以及形成于侧壁156c中并与基座壁156a的槽156b对准或对齐的齿轮齿条156d。齿轮齿条156d被构造为与钟形曲柄传动件154的正齿轮154d的齿轮齿154g接合。
施夹器100进一步包括使加速齿条156与驱动通道140互连的偏压元件158。
如在图6中可见，钟形曲柄传动件154的臂154c的槽154f被构造且定尺寸为可滑动地并可旋转地接收稳定器162的突块162d于其中。使用时，当驱动通道140向远侧平移时，使驱动通道140和加速齿条156互连的偏压元件158随后使加速齿条156向远侧移动。当加速齿条156向远侧移动时，由于稳定器162的突块162d搭在钟形曲柄传动件154的臂154c的槽154f中，因此加速齿条156使得钟形曲柄传动件154旋转并将稳定器162和推杆160依次推向远侧。
施夹器100进一步包括配置在通道组件108内及推杆160下方的夹承载器170。夹承载器170通常呈盒状结构，具有上壁170a、一对侧壁170b和下壁170c，限定一穿过其中的通道170d。夹承载器170包括多个分隔开的窗口172，所述窗口172形成于上壁170a内并延其长度纵向延伸。夹承载器170包括形成于下壁170c内并延其长度纵向延伸的细长窗口(未示出)。
如在图4中可见，一叠外科夹子“C”装载和/或保持在夹承载器170的通道(未示出)内，以在其内和/或沿其滑动。通道被构造且定尺寸为将一叠或多个外科夹子“C”以头尾相接的方式可滑动地保持于其中。
如在图4和图4F中可见，施夹器100进一步包括可滑动地配置在夹承载器170通道内的夹从动件(clip follower)174。如下面将要更详细地讨论的，夹从动件174位于这叠外科夹子“C”的后方，设置为在施夹器100致动期间将这叠夹子“C”向前推进。通过楔形板180的前后往复运动来致动夹从动件174。
如在图4F中可见，夹从动件174包括：限定了一平面的主体部174a，从主体部174a基本上向上和向后延伸出的远侧突起175，以及从主体部174a基本上向下和向后延伸出的近侧突起176。远侧突起175包括：在由主体部174a限定的所述平面下方向下延伸的远侧部175a；和在由主体部174a限定的所述平面上方向上延伸的近侧部175b。
远侧突起175的近侧部175b被构造且定尺寸为可选择地与形成于夹承载器170的上壁170a内的窗口172接合。使用时，夹从动件174的远侧突起175的近侧部175b接合在形成于夹承载器170的上壁170a内的窗口172中，防止了夹从动件沿在近侧方向平移或移动。
近侧突起176被构造且定尺寸为可选择地与形成于楔形板180内的窗口180b接合。使用时，夹从动件174的近侧突起176接合在形成于楔形板180内的窗口180b中，使得夹从动件174基于楔形板180的远侧移动而向远侧前进或移动。
如在图4中可见，施夹器100进一步包括可滑动地配置在手柄组件102和通道组件108内的楔形板180。楔形板180定位或配置在夹承载器170下方。楔形板180包括用于选择性操作地插在钳夹120之间的基本锥形的远端180a。楔形板180限定了：多个沿其长度纵向延伸并形成于其隆起部分中的间隔开的窗口或孔180b、位于孔180b远侧的远侧窗口或孔180c、以及定位在孔180c近侧的最近侧横向定向槽180d。
如在图4中可见，施夹器100包括由仓盖130支撑的远侧闭锁178。远侧闭锁178包括尾部或突起178a，所述尾部或突起178a基本上向后和向下延伸并构造且定尺寸为容纳在楔形板180的远侧窗口或孔180c中。
如在图4、4D、4E和6中可见，施夹器100包括楔形板运动反转机构(motion reversing mechanism)，其呈枢转臂179的形式，可枢转地支撑在外壳104的下半外壳104b上，用于将驱动通道140的平移传递成楔形板180的反转平移(reverse translation)。枢转臂179包括：被构造为可枢转地连接到外壳104上的枢转凸起部(boss)179a、位于枢转臂179的一端并沿与枢转凸起部179a相反的方向延伸的第一柱杆或指状部179b、以及位于枢转臂179的第二端并沿与枢转凸起部179a相反的方向延伸的第二柱杆或指状部179c。第一柱杆或指状部179b被构造为适于接合在楔形板180的最近侧槽180d中。第二柱杆或指状部179c被构造为接合在形成于驱动通道140中的槽140g中，其连接在限定于驱动通道140中的窗口140g中。槽140g包括彼此轴向和横向偏离的纵向延伸远侧部和纵向延伸近侧部，以及使远侧部和近侧部相互连接的横向部。
使用时，当驱动通道140向远侧移动时，在一滞留时间段(dwell period)之后(即，驱动通道140的槽140g的纵向延伸的远侧部的长度)，第二柱杆或指状部179c向远侧方向移动，使枢转臂179旋转，从而使第一柱杆或指状部179b沿第二方向移动。当第一柱杆或指状部17b沿第二方向移动时，第一柱杆或指状部179b将楔形板180从钳夹120之间拉出，推动推进器160的鳍状部160f以及向近侧推进或推动鳍状部160f以使推进器160沿近侧方向移动，从而使其推进器杆160c从钳夹120之间移出，反之亦然。当楔形板180向远侧方向移动时，如在图17中可见，楔形板180的远端180a凸靠(camagainst)钳夹120的内表面，从而保持钳夹120彼此间隔开。
如在图4和6中可见，施夹器100包括驱动通道140，其往复地支撑在手柄组件102的外壳104和通道组件108内并在二者之间延伸。驱动通道140的近端支撑在外壳104的上、下半外壳104a、104b之间，而驱动通道140的远端支撑在仓盖130和通道组件108的外部通道132之间，位于楔形板180的下方。

如在图4和6中可见，施夹器100进一步包括偏压元件146，其呈拉力弹簧的形式，可操作地固定到驱动通道140的近端和外壳104上并处于二者之间，趋向于保持驱动通道140处于缩回的或最近侧的位置。偏压元件146的作用在于在钳夹120之间成形夹子“C”之后使驱动通道140缩回或便于驱动通道140缩回。
如在图4和4H中可见，驱动通道140的近端包括棘轮齿条元件141，其固定在驱动销124上并可与驱动通道140一起移动。棘轮齿条元件141被构造为且适于与支撑在外壳104内的棘轮爪142接合。齿条元件141和棘爪142限定了棘轮机构144。使用时，当驱动通道140轴向移动时，齿条元件141也移动。齿条元件141限定了一系列具有一定长度的齿条齿141a，当随着驱动通道140到达最近或最远侧位置而使齿条元件141在近侧运动和远侧运动之间变化时，所述长度允许棘爪142倒退并返回到齿条元件141上。
通过棘爪销147将棘爪142可枢转地连接到下半外壳104b上，在此处棘爪142基本上与齿条元件141可操作地接合。棘爪142与齿条元件141能够接合以限制齿条元件141以及依次驱动通道140的纵向移动。棘轮机构144进一步包括棘爪弹簧145，其被构造且定位为将棘爪142偏压至与齿条元件141可操作的接合。棘爪弹簧145的作用在于保持棘爪142的齿与齿条元件141的齿141a啮合，以及保持棘爪142处于旋转或倾斜的位置。
如在图1至4中可见，施夹器100包括一对安装在通道组件108的远端上或远端处的钳夹120，其通过手柄组件102的手柄106来致动。钳夹120由适合的例如不锈钢或钛的生物相容性材料制成。
通过延伸穿过驱动通道140的往复限制槽140f的铆钉122或类似物将钳夹120安装在驱动通道140的远端，以使得钳夹120相对于外部通道132和驱动通道140是纵向静止的。
如在图1至4和6中可见，施夹器100进一步包括支撑在手柄组件102的外壳104中的计数器机构190。下文将参考图17更详细的描述计数器机构190。计数器机构190包括由PVC制成的突起192a，突起192a设置在电池或能源198和开关194的触点194a之间或设置在开关194的触点194a之间以防止电池或能源198在存放过程中被耗尽。如在图1A和1B中可见，突起192a从施夹器100的外壳104向外部延伸以允许该突起易于从外壳移除。一旦移除突起192a，电池或能源198与开关194的触点194a电接触或在开关194的触点194a之间形成电接触。可通过形成于驱动通道140中的突块140e来致动计数器机构190。使用时，如在图6中可见，当向前驱动驱动通道140时，其突块140e与触点194a接合使得触点194a形成一电路。在另一实施例中，如上在图4中可见，施夹器100可设置有被构造为将能源198固定到外壳104上的条片196。

如在图17中可见，通常用800表示依照本公开的实施例的计数器机构。计数器机构800向显示单元900(图18)发送信号以显示夹子的数目。计数器机构800包括向计数器机构800中的电路提供电力的电池802。电池802可由将交流(AC)电源转换为直流(DC)电源的动力源替换。计数器机构800包括开关804。当按如前所述致动开关804时(采用施夹器100的计数器机构190的开关194和/或施夹器1000的计数器机构1320的开关1324的方式)，开关804形成向编码器806提供信号或脉冲的电路。编码器806可提供具有单个比特的比特序列来指示开关804已被启动，或提供具有至少两个比特的比特序列来指示开关804未被启动。比特序列可具有数据头和数据部分，所述数据头能识别由临床医师使用的施夹器或将接收所发送的比特或比特序列的显示器，所述数据部分指示已施加的夹子和/或确定由计数器机构800发送的信号是否正确的错误校正码。编码器806向射频(RF)发送器808提供比特或比特序列。RF发送器808将信号转换成RF信号并通过发射天线810发射该RF信号。
如在图18和19中可见，通常用900表示依照本公开实施例的显示器单元。显示器单元900包括接收天线902，该接收天线902接收来自计数器机构800的发送器808的RF信号并将该RF信号传送给RF接收器904。RF接收器904接受该RF信号并将该RF信号转换成比特序列。将比特序列提供给将该比特序列解码的解码器906。解码器906可确定显示器单元900是正确的显示器单元，以使用数据头信息接收该比特序列。解码器906还可确定接收到的比特序列是没有错误的，并且如果所接收到的比特序列确实存在错误的话，则解码器906可校正该错误或要求从计数器机构800重新发送该比特序列。
解码器906向二进制编码的十进制(BCD)计数器908提供信号或脉冲。BCD计数器908包括计十位的BCD计数器908a和计个位的BCD计数器908b。当开启显示器单元900时，表示施夹器中夹子数目的默认数字将存储在存储器中(未示出)。当BCD计数器908从解码器906接收到一信号时，BCD计数器将对默认数字加一或减一。例如，当BCD计数器908接收一信号时，第二BCD计数器908b可将计数加一。当第二BCD计数器908b中的计数达到10时，则例如第一BCD计数器908a中的计数加一。反过来，如果计数递减的话，当BCD计数器908接收一信号时，第二BCD计数器908b可将计数减一。当第二BCD计数器908b中的计数到达0时，则第一BCD计数器908a中的计数减一。
BCD计数器908向BCD解码器/驱动器912提供二进制编码信号。BCD解码器/驱动器912包括从第一BCD计数器908a接收信号的第一BCD解码器/驱动器912a和从第二BCD计数器908b接收信号的第二BCD解码器/驱动器912b。BCD解码器/驱动器912将接收到的二进制编码信号进行解码并将该信号输出给显示器914。显示器914向外科医师显示一个或多个施夹器的操作参数。由显示器914显示的操作参数包括剩余夹子的数量或数目、已经使用的夹子的数目或过程中的其它任意参数。显示器914包括一对七段发光二极管(LEDs)914a和914b。第一LED 914a显示由第一BCD解码器/驱动器912a提供的十位数，而第二LED 914b显示由第二BCD解码器/驱动器912b提供的个位数。
由动力源916向显示器单元900提供电力。动力源916可连接至交流电源或其它任何电源，交流电源例如是110v/220v墙面上的电源(wall source)。动力源916能将AC电源转换为足够的DC电压以向显示器单元900的零件提供电力。备选地，动力源916可包括串联或并联的一个或多个电池以向显示器单元900的零件提供充足的电力。
显示器单元900还提供了“加电”/“复位”开关918。当显示器914上所显示的计数到达0或某个预定的数字时，开关918可用于将显示器914复位为存储在显示器单元900中的默认数字或重置为0。还可提供“与”门910，以便就BCD计数器908a和BCD计数器908b而言，当BCD计数器908中的计数到达0时，与门910将计数保持在0。
在此描述的实施例仅仅是示意性的，并不旨在限制本申请的范围。本领域技术人员能很容易地认识到，当前所描述的实施例可用在各种外科施夹器中。例如，序列号为No.12/406,345的美国专利申请，将其整个内容也通过引用并入于此，其中在外科施夹器上使用了光学路径，当路径被破坏时，可向计数器机构提供信号以将计数递增或递减。
进一步，显示器单元可包括执行上述零件的所有功能并向显示器输出信号的微处理器。显示器可为具有任何数量的七段发光二极管以适应任意数量的数位或可以是液晶显示器。
可以理解的是，之前的描述仅仅是本公开示意性的描述。所属领域技术人员不脱离本公开可设计多种变形和修改。因此，本公开旨在包含所有这些变形、修改和变化。参考随附的附图描述的实施例仅仅展示了本公开的特定实例。其它非实质性不同于以上描述和/或附加的权利要求的元件、步骤、方法和技术也希望包括在本公开的范围内。
