具体实施方式
现在将参照附图详细描述本公开的手术吻合装置的各个实施例，其中相同的附图标记指明的是相似或者相同的构造元件。在附图中和在以下说明书中，术语“近侧”指的是设备或者系统的最靠近操作者的端，而术语“远侧”指的是设备或者系统的距离操作者最远的端。
手术吻合装置在图1中被图示出并且以附图标记10代表。手术吻合装置10包括手柄组件20、从手柄组件20向远侧延伸出的细长体30和可释放地紧固到细长体30的远侧端的一次性装载单元40。一次性装载单元40包括机具组件42，机具组件42具有钉仓组件160和相对于钉仓组件160可活动地紧固的砧座组件150。一次性装载单元40构造为连续地施加线性成行的吻合钉。
手柄组件20包括静止手柄构件22、活动手柄构件24和筒形部分26。可旋转构件28被安装在筒形部分26上以利于细长体30相对于手柄组件20的旋转。邻近于可旋转把手28在筒形部分26的远侧端部上设置有关节式运动杠杆29以利于机具组件42的关节式运动。致动轴(未示出)被支撑在筒形部分26内。致动轴可操作地联接至活动手柄构件24，以使得手柄构件24在图1的箭头“B”的方向上的枢转运动轴向地推进致动轴，这依次引起手术吻合钉的发射。收缩把手27附着至致动轴。收缩把手27沿着筒形部分26可活动地定位以使得致动轴返回到收缩位置。
现在参照图2，一次性装载单元40包括机具组件42和近侧壳体部分46，近侧壳体部分46适于将一次性装载单元40可释放地接合至细长体30。安装组件48可枢转地紧固至壳体部分46的远侧端部以使得安装组件48绕着与壳体部分46的纵轴线“A-A”垂直的轴线的枢转运动实现了机具组件42的关节式运动。通过附着到吻合器械10的一次性装载单元40，机具组件42能够定位在组织周围。为了夹紧砧座组件150和钉仓组件160之间的组织，静止手柄构件22在图1中的箭头“B”所示的方向上运动。在第一冲程期间活动手柄构件24的一个完整冲程仅足以夹紧组织而不是发射吻合钉(即接近砧座组件150和钉仓组件160)地推进致动轴。为了发射吻合钉，活动手柄构件24被再次致动，即通过另一个冲程运动。
机具组件42包括砧座组件150和钉仓组件160。如在图6中最佳可见，砧座组件150包括限定多个手术吻合钉形变凹部154的砧座部分152和紧固到砧座部分152的顶表面上的盖板151。参照图3至图6，吻合钉钉仓组件160包括限定了多个挡槽168的吻合钉钉仓162和可释放地联接至吻合钉钉仓162的底部的钉仓底板161。钉仓底板161限定了定尺寸为以及构造为接收吻合钉钉仓162的细长支撑槽161a。分别沿着吻合钉钉仓162和钉仓底板161形成的相应的翼片163和狭缝167以起到将吻合钉钉仓162保持在支撑槽161a内的作用。形成在吻合钉钉仓162上的一对支撑支柱164定位成静置在钉仓底板161的侧壁上以进一步使得吻合钉钉仓162稳定在支撑槽161a内。形成在砧座部分152上的一对枢转构件155定位在形成在钉仓底板161中的狭缝177内以在开启位置和夹紧之间对砧座部分152进行导向。
如在图4中最佳所示，挡槽168从邻近于底板161的吻合钉钉仓162的底部延伸至组织接触表面169。组织接触表面169限定了与挡槽168连通的多个狭缝168a。挡槽168和狭缝168a与砧座组件150的多个手术吻合钉形变凹部154对准。如下文将详细描述的，多个挡槽168将多个推件166和具有编码嵌入部分的手术吻合钉100容纳在其中。
每个手术吻合钉100支撑在相应的推件166上。如在图4中最好地示出的，吻合钉钉仓162进一步限定了适于将轴向平移的致动滑座170接收在其中的间隔开的纵向狭缝172。随着致动滑座170向远侧平移而通过吻合钉钉仓162的纵向狭缝172，凸轮楔件176顺序地接合推件166。凸轮楔件176使得推件166在挡槽168内朝向于组织接触表面169平移，从而从狭缝168a朝向于砧座组件150的吻合钉形变凹部154发射吻合钉100。任选地，可以在吻合钉钉仓162上进一步设置纵向延伸的中央狭缝174以利于在将成行的吻合钉100施加到切割线的对侧上的同时使得组织分离的刀片(未示出)的通过。
如在图2中最佳所示，一次性装载单元40的近侧壳体部分46由包含在外壳57内的上壳体半部和下壳体半部形成。近侧壳体部分46的近侧端包括用于与细长体30可释放地接合的接合块58，通过诸如与细长体30的远侧端部的卡扣型联接而接合。在6,953,139号美国专利中公开了适当的吻合器械的示例，其全文通过引用合并于此。
现在参照图7，本公开的实施例大体上示为手术吻合钉100。吻合钉100包括一对支腿102、104和后跨部110。每个支腿102、104包括相应的编码嵌入部分106、108以及相应的构造为和定尺寸为穿透组织的穿透远侧尖端102a、104a。在未成形的位置上，吻合钉100具有大致平坦的轮廓，其中支腿102、104与后跨部110处于同一个平面中。特别地，支腿102、104大致上是直的并且垂直于后跨部110的纵轴线“Z-Z”。但是，因为支腿102、104还能够相对于后跨部110成其他角度而定位，即不垂直于后跨部110，所以支腿102、104不需要是平行的。
参照图8至图10，吻合钉钉仓162包括多个感测器180。如在图8中最佳所示，每个感测器180嵌入在限定挡槽168的侧壁165中，在被射出之前吻合钉100被装载在挡槽168中。感测器180被放置在侧壁165中以使得当吻合钉100被正确地装载进挡槽168中并且被支撑在相应的推件166上时，吻合钉100的编码嵌入部分106、108与感测器180对准。感测器180可以采用，诸如机械、光学、磁性或者电气装置以确定编码嵌入部分106、108是否与感测器180对准。特别地，感测器180可以暴露在挡槽168中。在一些情形中，当手术吻合钉100被正确地装载进相应的挡槽168中时，暴露在挡槽168中的感测器180可以与编码嵌入部分106、108中的一个直接接触。由感测器180收集的数据，即编码嵌入部分106、108是否与相应的感测器180对准，可以通过电线185或者无线装置(未示出)发送给处于相对远程位置的用户。这些数据可以由处理单元进行处理，处理单元可以设置在手柄组件20或者外部终端(未示出)上。在手术吻合钉100的成形之前以及期间，结合吻合钉100的感测器180允许用户监测吻合钉100的位置/状态。
吻合钉的编码嵌入部分106、108可以是能够由磁性、电子或者光学感测器180读取的编码。因此在磁性感测器180的示例中，感测器180可以是霍尔效应感测器，并且编码嵌入感测器部分106、108可以涂覆有磁墨水。类似地，电子感测器180可以，诸如测量吻合钉的编码嵌入部分106、108的电阻，吻合钉的编码嵌入部分106、108可以镀有诸如银等低电阻生物相容性材料或者涂覆有诸如聚合物等高电阻材料。光学感测器180可以与吻合钉的编码嵌入部分106、108一起实施，吻合钉的编码嵌入部分106、108被涂刷或者以其他的方式进行处理以改变颜色、反射系数或者其他光学品质。
但是，感测器180的放置可以修改为满足正在实施的手术操作的特定需要。诸如，感测器180可以放置在自正确装载的吻合钉100的编码嵌入部分106、108偏移的位置处，以使得当吻合钉未被正确地装载进槽168中时，编码嵌入部分106、108与放置在偏移位置处的感测器180对准。因此，感测器180检测未正确装载的吻合钉100。此外，放置在偏移位置处的感测器180可以检测正确装载的吻合钉100的发射或者误发射。在吻合钉100正确发射的情形中，处于偏移位置的感测器180可以检测吻合钉100的编码嵌入部分106、108的通过。在吻合钉100误发射的情形中，感测器180可以检测位于偏置位置的误发射吻合钉100的编码嵌入部分106、108，即编码嵌入部分106、108未经过处于偏移位置的感测器180，而是与处于偏移位置的感测器180对准。此外，可预想的是，可以将编码嵌入部分106、108放置在后跨部110中以检测吻合钉100的正确装载和/或误发射。在这种布置下，感测器180将被放置在钉仓162的底部中或者钉仓底板161中。
继续参照图9和图10，砧座组件150包括砧座感测器系统190、限定多个凹部154的砧座部分152和紧固到砧座部分152的顶表面上的盖板151。如在图9中最佳所示，每个凹部154包括用于使相应的支腿102、104变形的凹进部分154a、154b。一对感测器192、194邻近于凹部154的相应凹进部分154a、154b嵌入以使得当吻合钉100相对于凹部154的凹进部分154a、154b正确地成形并且从而成为“B-形”吻合钉100时，编码嵌入部分106、108分别与感测器192、194对准。类似于感测器180，感测器192、194可以采用，诸如机械、光学、磁性或者电气的装置以确定吻合钉100的编码嵌入部分106、108是否与相应的感测器192、194对准。可以构想，在某些情形中，嵌入在砧座部分152中的感测器192、194可以部分地暴露到编码嵌入部分106、108。特别的是，在吻合钉100正确成形之后，吻合钉100的编码嵌入部分106、108可以分别与感测器192、194直接接触。此外，吻合钉的编码嵌入部分106、108可以具有由吻合钉成形的变型或者变形期间的机械刮削而修改的编码。因此可以去除磁墨水或者减小磁场，吻合钉的编码嵌入部分106、108的电阻可以改变或者其光学特性可以改变，以使得来自感测器180和感测器192、194的数据可进行比较以进一步保证正确的成形。
感测器192、194通过电线195或者无线装置(未示出)将信号发送到相对远程的位置，其中所述信号由处理单元进行处理。由处理单元处理的数据为用户显示在手柄组件20上或外部终端(未示出)上，所述用户将监测吻合钉100是否已经正确地成形，即编码嵌入部分106、108是否与相应的感测器192、194正确地对准。可选地，输出数据可以直接由自动/处理器从动系统进行处理以控制吻合钉成形。在任何一种情形中，在手术吻合钉100的发射之后砧座感测器系统190结合吻合钉100允许用户监测吻合钉100的位置/状态且从而判定是否发生了吻合钉100的正确成形。通过采用砧座感测器系统190和钉仓感测器180，用户能够在器械使用之前确认吻合钉的存在以及手术吻合钉100的发射之后确认吻合钉的正确成形。此外，用户能够监测是否所有的吻合钉已经被发射。此外，用户能够控制吻合钉成形以防止在吻合钉的欠成形或者过成形和/或补偿变化的组织厚度或者特性。如通过感测器180描述的，可以进一步构想，感测器192、194可定位为偏离于正确成形的吻合钉100的编码嵌入部分106、108，以使得未正确成形的吻合钉100的编码嵌入部分106、108与处于偏移位置的感测器192、194对准。
在使用时，如图10所示使得组织“T”夹紧在砧座组件150和钉仓组件160之间，根据本领域技术人员已知的方法来使用手术吻合器械10。此时，包括编码嵌入部分106、108的吻合钉100装载在相应的挡槽168中。正确地支撑在挡槽168内的相应推件166上的吻合钉100允许编码嵌入部分106、108与嵌入在挡槽168的相应侧壁165中的感测器180对准。如上文描述的，感测器180可以采用诸如机械、光学、磁性或者电气装置，以判定编码嵌入部分106、108是否与感测器180对准，通过电线185或者无线装置(未示出)将感测器180获得的数据发送到处于相对远程位置的处理单元。如上文所述，数据可以由处理单元进行处理，所述处理单元可以设置在手柄组件20或者外部终端(未示出)上。同样地，在多个手术吻合钉100发射之前以及发射期间，结合吻合钉100的感测器180允许用户监测多个吻合钉100的位置/状态。
在确定吻合钉100被正确地装载在相应的挡槽168中时，即，在吻合钉100的各个编码嵌入部分106、108与相应的感测器180对准时，用户现在准备好将吻合钉100发射进组织“T”中，以用于诸如在切除之前组织的闭合或者用于器官的闭塞。如上文所述用户通过操纵手柄组件20来发射吻合钉100。手柄组件20的操纵引起致动轴在远侧方向上的轴向运动，这依次向远侧驱动致动滑座170。如图11所示，凸轮楔件176顺序地与多个推件166形成接触，这依次迫使推件166在箭头“U”的方向上朝向于砧座组件150推进。支撑在相应的推件166上的各个吻合钉100朝向于砧座组件159被推动并且从挡缝168a被发射而通过组织“T”。吻合钉100的穿透远侧尖端102a、104a对着凹部154被推动并且朝向于后跨部110被弯曲，从而形成“B-形”吻合钉100。如图11所示，正确地成形的“B-形”吻合钉100提供了编码嵌入部分106、108以便与邻近于砧座部分152中的相应凹进部分154a、154b布置的相应的感测器192、194对准。如上文所述，取决于所使用的感测器180的类型，感测器192、194可以定位在邻近于凹部154的砧座部分152内，以使得当吻合钉100已经正确地成形时编码嵌入部分106、108与相应的感测器192、194之间发生直接的接触。
然后，感测器192、194通过电线195或者无线装置将信号发送到位于相对远程位置上的处理单元。处理单元对信号进行处理并且将是否发生了吻合钉100的正确成形显示在手柄组件20上或者外部显示终端上。监测吻合钉100是否已经正确地成形，即编码嵌入部分106、108是否与相应的感测器192、194正确地对准的用户将确定动作的下个过程。同样地，在发射之后以及发射期间，结合吻合钉100的砧座感测器系统190允许用户监测吻合钉100的位置/状态。
如图11所示，不具有完整成形的“B-形”构造的最远侧的吻合钉100缺乏编码嵌入部分106、108与相应的感测器192、194之间的正确对准。这种状态将被显示在手柄组件20上或者显示在外部显示终端上。
现在参照图12，如“B-形”吻合钉100的正确成形所表示的并且由在吻合钉钉仓162的最远侧位置处的致动滑座170进一步证实的，完成了组织“T”的吻合。这里，所有的吻合钉100已经正确地成形。同样地，每个单个的吻合钉100的编码嵌入部分106、108与相应的感测器192、194正确地对准。此时，感测器系统190将收集的指示所有吻合钉100的正确成形的数据发送到其中用户能够对数据进行处理的相对远程位置。此时，获知了所有的手术吻合钉100已经正确地成形，用户能够实施其他手术操作。但是，如果多个手术吻合钉100的任何一个缺陷地或者非完整地成形，在执行其他手术操作之前用户可以重复该过程以纠正问题。
参考图13和图14，示出了根据本公开的具有编码嵌入部分506、508的手术吻合钉500的另一个实施例。吻合钉500包括限定凹槽512的后跨部510和分别具有组织穿透尖端502a、504a的一对支腿502、504。一对支腿502、504以一定的角度，即非垂直于后跨部510从后跨部510延伸出。在薄组织的情形中，凹槽512为一对支腿502、504提供了额外的行进长度。因此，即使是在吻合薄组织的情形中，组织穿透尖端502a、504a将不会被驱动而进入后跨部510中，导致手术吻合钉500不期望的弯曲。此外，这种设计防止支腿502、504被驱动而经过后跨部510，这依次可能抑制相邻组织的穿透。吻合钉500的操作和使用与吻合钉100是实质相同的并且出于简洁的考虑将被省略。
如图15和图16所示，进一步构想，使公开的吻合钉位置感测器系统能够构造为与诸如圆形吻合器械1000以及横向吻合器械2000一起使用。典型地，这些装置的每个包括具有致动器1022、2022的壳体1020、2020、可操作地联接到致动器1022、2022上的致动机构和机具组件1040、2040。每个致动器1022、2022可活动以实现致动机构的推进，所述致动机构实现吻合钉100相对于限定在每个砧座组件1050、2050中的多个凹部的成形。机具组件1040、2040可操作地联接到致动机构上。每个机具组件1040、2040具有钉仓组件1060、2060和相对于钉仓组件1060、2060可活动地安装的砧座组件1050、2050。每个机具组件1040、2040容纳上文描述的吻合钉位置感测器系统。特别地，具有编码嵌入部分106、108的多个吻合钉100布置在钉仓组件1060、2060中。钉仓组件1060、2060均包括检测吻合钉100在钉仓组件1060、2060中的挡槽中的正确装载的感测器。每个砧座组件1050、2050包括砧座感测器系统，所述砧座感测器系统包括邻近于限定在相应的砧座组件1050、2050中的凹部布置的一对感测器。应当注意的是，虽然本公开的吻合钉位置感测器系统在上述实施例中是相对于内窥镜/腹腔镜器械详细描述的，但是吻合钉位置感测器系统并不限于这种吻合器械。本公开的吻合钉位置感测器系统能够用于在开放式手术操作中使用的器械中，诸如如图16所示的横向吻合器械2000。
将要理解的是，可以对本公开的手术夹和夹施夹器的实施例做出各种改进。因此，上述说明不应当被理解为限定性的，而仅仅作为实施例的示例。本领域技术人员将设想到在本公开的范围和精神内的其他改进。
