具体实施方式
本领域技术人员将理解，本文所具体描述并且在附图中示出的装置和方法是非限制性示例性实施例。可以想到，在不偏离本公开的范围的前提下，结合一个示例性实施例所示出或描述的元件和特征可以与其他实施例的元件和特征相组合。同样，本领域技术人员将基于上述实施例来理解本公开的其他特征和优点。因此，除了所附权利要求所指出的内容之外，本公开不受具体示出和描述的内容的限制。
如本文中所使用的，术语远侧指的是装置离临床医生最远的部分，而术语近侧指的是装置离临床医生最近的部分。此外，如本文所使用的，术语临床医生指的是包括医生、护士和辅助人员的医务人员。
本文公开的外科吻合装置包括枢转指示器，所述枢转指示器支撑在外科吻合装置的手柄组件上。所述指示器响应于外科吻合装置从未接近位置移动至接近位置而从第一位置枢转至第二位置，以向临床医生指示吻合装置处于击发就位位置。外科吻合装置还包括指示器连接件，所述指示器连接件定位成与指示器接合并且响应于外科吻合装置的击发触发器的致动而将指示器从第二位置移动至第三位置，以向临床医生指示外科吻合装置已经被击发。下文将详细描述外科吻合装置。
图1示出了本文公开的外科吻合装置(通常表示为附图标记10)的一个实施例。外科吻合装置10包括手柄组件12、本体14、盒组件或壳体组件16和砧座组件18，所述本体14从手柄组件12向远侧延伸，所述盒组件或壳体组件16支撑在本体14的远侧端部上，所述砧座组件18相对于壳体组件16被可移动地支撑在与壳体组件16间隔开的位置和与壳体组件16并列对准的位置之间。手柄组件12包括外壳20、击发触发器22、接近旋钮24和指示器26，所述击发触发器22枢转地支撑在外壳20上，所述接近旋钮24可旋转地支撑在外壳20上，所述指示器26通过形成为穿过外壳20的上壁的窗口28可见。如图所示，指示器26可以具有球形或凸形形状使得指示器26穿过窗口28突出。指示器26的球形形状允许从吻合装置10的相对两侧观察指示器26。美国专利No.7303106(“‘106专利”)公开了一种外科吻合装置，所述外科吻合装置包括进一步详细描述的许多相同的部件和机构，并且其全部内容通过引用并入本文。
还参照图2，手柄组件12支撑接近组件30。接近组件30包括接近旋钮24(图1)、中空套筒32、固定地紧固至中空套筒32的一端部的套环(collar)34、和传动螺杆36。传动螺杆36具有近侧端部和远侧端部，所述近侧端部延伸穿过套环34并且进入中空套筒32，所述远侧端部可操作地连接到砧座组件18。传动螺杆36包括螺旋凹槽(未示出)，所述螺旋凹槽接收支撑在套环34上的销38。
接近旋钮24(图1)、套筒32和套环34可旋转地支撑在手柄组件12的外壳20的近侧端部上，其中销38接收在螺旋凹槽内。套环34限定了环形凹槽40，所述环形凹槽40接收形成在外壳20的内壁上的凸缘42，以将套环34轴向地固定在外壳20内。因此，当相对于外壳20的近侧端部致动或旋转接近旋钮24时，销38在传动螺杆36的螺旋凹槽(未示出)内移动，以实现传动螺杆36线性移动进入中空套筒32和线性移动离开中空套筒32。已经通过引用并入本文的‘106专利公开了与接近组件30基本上相类似的接近组件。
使用例如固定螺钉44将螺杆止动件42轴向地固定至传动螺杆36。螺杆止动件42包括向上指向的突出部46，所述突出部46将在下文进一步详细讨论。当接近旋钮24被致动并且传动螺杆36在手柄组件12的外壳20内线性移动时，包括突出部46的螺杆止动件42也在外壳20内线性移动。
击发触发器22通过枢转销50枢转地联接至推动器连接件48的近侧端部。如下文将详述的，如本领域中所已知的，推动器连接件48接合定位在壳体组件16(图1)中的推动器(未示出)，以当击发触发器22被致动时将吻合钉从壳体组件16射出。击发触发器22的中心部分56通过枢转构件60枢转地联接至击发连接件58的远侧端部。击发连接件58的近侧端部支撑传动销62，所述传动销62定位成当击发触发器22被致动时接合形成在螺杆止动件42上的后挡部64(图4)。更具体地，当击发触发器22被致动时(即朝向手柄组件12的外壳20受压时)，传动销62接合螺杆止动件42的后挡部64，而击发连接件58的远侧端部朝向外壳20枢转，以向远侧推进(advance)推动器连接件48。
参照图2-图5，击发连接件58包括侧向延伸部66。指示器连接件68可滑动地定位在槽70(图9和10)内，所述槽70限定在外壳20的内壁中。指示器连接件68包括中心本体部分72、上部部分74和下部部分76。中心本体部分72可滑动地接收在外壳20内的槽70中，使得当击发触发器22被致动时，上部部分74定位成接合指示器26的底部表面，而下部部分76定位成接合击发连接件58的侧向延伸部66。
还参照图6-图10，本文公开的外科吻合装置10包括指示器机构，所述指示器机构包括指示器26、透镜盖82(图5)和滑动构件84(图6)。指示器26围绕枢转构件86被枢转地支撑，所述枢转构件86可以一体地形成在外壳20的内壁上。可替代地，枢转构件86可以与外壳20分别形成。透镜盖82定位在指示器26上方并且限定了槽82a，指示器26可以通过所述槽82a而可视化。滑动构件84(图6)包括本体部分92、远侧抵接构件或上翘唇部部分96、和近侧延伸部98，所述本体部分92在其中形成有细长槽94。滑动构件84可滑动地定位在外壳20中。近侧延伸部98通过支撑结构100(图2)可滑动地支撑在外壳20中，所述支撑结构100可以与外壳20一体形成。偏压构件(例如螺旋弹簧102)定位成围绕近侧延伸部98在滑动构件84的支撑结构100和本体部分92之间处于压缩状态，以在外壳20内向远侧迫压滑动构件84。
还参照图7和图8，唇部部分96的上侧端部包括圆柱形连接器96a。指示器26包括一对间隔开的细长凹部106(图7，仅示出一个凹部)，所述细长凹部106接收圆柱形连接器96a的相对的端部。如下文将详述的，在吻合装置10的未接近位置处，偏压构件102(图2)将滑动构件84迫压到其最远侧位置，以将指示器26枢转至第一位置，这为临床医生提供了吻合装置10还未接近并且未处于击发就位状态的指示。
如上所述，螺杆止动件42固定地附接到传动螺杆42(图2)，并且包括突出部46。突出部46定位成延伸(travel)穿过滑动构件84的槽94，并且在吻合装置10接近期间接合槽94的近侧端部94a(图6)。当螺杆止动件42的突出部46抵接槽94的近侧端部94a时，吻合装置10的进一步接近抵抗弹簧102的偏压在外壳20内向近侧移动滑板84。随着滑板84在外壳20内向近侧移动，滑动构件84的圆柱形连接器96a(所述圆柱形连接器96a在与枢转构件86偏置的位置处定位在指示器26的细长凹部106内)实现了指示器26围绕枢转构件86从第一位置枢转移动到第二位置，从而为临床医生提供吻合装置10处于接近和击发就位位置的指示。
参照图7和图8，指示器26包括本体110(具有顶部表面112)、一对间隔开的铰接构件114、限定细长凹部106的内部表面116。铰接构件114从本体110向下延伸，并且限定了接收枢转构件86(图10)的开口118。本体110还限定了抵接表面120，所述抵接表面120定位在铰接构件114之间。如下文进一步详述，当击发触发器22被致动时，抵接表面120定位成接合指示器连接件68的上部部分74。指示器26的本体110的顶部表面112包括标记，所述标记指示指示器26的三个不同位置。如上所述，指示器26的第一位置为临床医生提供吻合装置处于未接近位置并且尚未击发就位的指示，而指示器26的第二位置为临床医生提供吻合装置已经接近并且处于击发就位位置的指示。如下所述，指示器26能够移动到第三位置，所述第三位置为临床医生提供吻合装置10已经被击发的指示。
设置在指示器本体110的顶部表面112上的标记可以包括各种不同颜色或字母数字标志，以区分或识别指示器的每个位置。在实施例中，标记包括设置在指示器26的顶部表面112上的三种不同颜色，例如红色(R)、绿色(G)和粉色(P)。颜色R、G和P定位在指示器26的顶部表面112上，使得当指示器26定位在其第一位置时，第一颜色(例如R)通过透镜盖82中的槽82a(图5)可见，当指示器26定位在其第二位置时，第二颜色(例如G)通过透镜盖82中的槽82a可见，而当指示器26定位在其第三位置时，第三颜色(例如P)通过透镜盖82中的槽82a可见。可替代地，颜色可以由各种不同的字母、数字或符号代替。
参照图11A-图11C，在致动外科吻合装置10之前(图1)，在吻合装置10处于未接近位置的状态下(图1A)，指示器26处于其第一位置，使得颜色R通过透镜盖82中的槽82a可见。此外，指示器连接件68的上部部分74定位成靠近指示器本体110的抵接表面120，并且下部部分76与击发连接件58的侧向延伸部66间隔开。如图所示，螺杆止动件42与接近机构的套环34远侧地间隔开，并且滑动构件84在偏压构件或弹簧102处于未压缩状态的情况下处于其最远侧位置。如图所示，螺杆止动件42的突出部46定位在滑动构件84的细长槽94的远侧端部中。
图11D示出了处于部分接近位置的吻合装置10，其中已经通过致动接近旋钮24(图1)使吻合装置10接近从而朝向盒组件16移动砧座组件18。在所示的部分接近位置中，定位在套环34的远侧的螺杆止动件42已经与传动螺杆36一起向近侧朝向套环34移动，使得传动螺杆36的突出部46已经从槽94的远侧端部移动到与槽94的近侧端部94a相邻的位置。如图所示，吻合装置10未处于完全接近位置。因此，螺杆止动件42的突出部46还没有在外壳20内向近侧移动滑动构件84，并且因此，滑动构件84仍然处于其最远侧位置。
参照图12A-图12C，当吻合装置10(图1)从图11D中所示的部分接近位置移动到完全接近位置以将砧座组件18移动到与盒组件16并列对准时，螺杆止动件42的突出部46在槽94的近侧端部94a(图12C)处接合滑动构件84，并且将滑动构件84在外壳20内缩回。如图12C中可视，随着滑动构件84在外壳20内向近侧移动，经由滑动构件84的唇部部分96的圆柱形连接器96a连接到指示器26的滑动构件84使得指示器26沿顺时针方向从其第一位置枢转至其第二位置。如上所述，在指示器26的第二位置处，第二颜色(例如G)通过透镜盖82中的槽82a可见，以为临床医生提供吻合装置10处于接近位置的指示。注意到，在传动螺杆36的完全缩回位置处，螺杆止动件42与套环34接合(图12C)。
参照图13A-图13C，在已经将吻合装置移动到完全接近位置之后，能够击发吻合装置以从盒组件16中射出吻合钉。通过朝向手柄组件12的外壳20枢转击发触发器22击发吻合装置10。如上所述，随着击发触发器22朝向手柄组件12的外壳20枢转，击发连接件58朝向外壳20枢转，使得形成在击发连接件58的至少一侧上的侧向延伸部66接合指示器连接件68的下部部分76，以在手柄组件12的外壳20内的槽70内向上移动指示器连接件68。随着指示器连接件68在槽70内向上移动，指示器连接件68的上部部分74压抵指示器26的抵接表面120，以将指示器26从其第二位置枢转到其第三位置。在第三位置处，第三颜色(例如P)通过透镜盖82中的槽82a可见，以为临床医生提供吻合装置10已经被击发的指示。
本领域技术人员将理解，本文所具体描述并且在附图中示出的装置和方法是非限制性示例性实施例。可以想到，在不偏离本公开的范围的前提下，结合一个示例性实施例所示出或描述的元件和特征可以与其他实施例的元件和特征组合。同样，本领域技术人员将基于上述实施例来理解本公开的其他特征和优点。因此，除了所附权利要求所指出的内容之外，本公开不受具体示出和描述的内容的限制。
