在某些实施例中，切口界定上通道部分和下空腔部分，并且销可沿着下空腔部分的近端壁朝上从第一位置移动到第二位置，且可在上通道部分内向近侧从第二位置移动到第三位置。
在实施例中，发声器包含下部部分，所述下部部分具有突片，所述突片定位成接合击发连杆上的突片。
在一些实施例中，驱动螺钉支撑对接件，并且发声器包含上部部分，所述上部部分定位成在击发组件的致动冲程之后当发声器朝上移动到第三位置时接合所述对接件。
在某些实施例中，固定手柄包含界定插槽的支架，并且当发声器处于第三位置时发声器的上部部分延伸穿过所述插槽。
在实施例中，当砧座组件相对于套筒组件从合拢位置朝向分隔位置移回时对接件可沿着支架移动，从而将发声器从第三位置朝向第二位置移回。
在一些实施例中，对接件被配置成当砧座组件相对于套筒组件朝向完全分隔位置移回时使发声器枢转，使得对接件越过发声器以使发声器能扣接回到第一位置，从而提供砧座组件已经返回到分隔位置的第二可听指示。
在本公开的另一方面中，一种手术钉合装置包含具有固定手柄和击发触发器组件的手柄组件，所述击发触发器组件可移动通过致动冲程。中心主体从手柄组件向远侧延伸，并且套筒组件支撑在中心主体的远端上。所述手术钉合装置还包含砧座组件以及包含可纵向移动的驱动螺钉的合拢机构。驱动螺钉以操作方式连接到砧座组件，使得驱动螺钉的纵向移动影响砧座组件相对于套筒组件在分隔位置与合拢位置之间的移动。在手柄组件中提供可听指示器机构，并且所述可听指示器机构包含发声器和偏置构件，其中所述发声器适于接合击发组件从而向临床医生提供击发触发器已完成击发冲程的可听指示，并且适于接合合拢机构从而向临床医生提供在致动冲程之后砧座组件已移回至分隔位置的可听指示。

具体实施方式
现将参考附图详细描述当前公开的手术钉合装置，在附图中，相同参考标号指代若干视图中的每个视图中的相同或对应元件。在此描述中，术语“近端”通常用来指装置的较接近于临床医生的部分，而术语“远端”通常用来指装置的距临床医生较远的部分。另外，术语“内窥镜”通常用来指包含内窥镜、腹腔镜和关节镜等通过小切口或插入到患者身体内的插管执行的手术。最后，术语“临床医生”通常用来指医务人员，包含医生、护士和辅助人员。
当前公开的手术钉合装置包含手柄组件，所述手柄组件支撑包含弹簧偏置发声器的可听指示器机构。弹簧偏置发声器定位成在手术钉合装置的击发期间接合击发触发器组件并且在手术钉合装置的未合拢期间接合螺钉止动器，并且包含销，所述销收纳于手柄组件的固定手柄的外壳中的销槽或空腔内。所述销可响应于击发触发器组件的启动和砧座组件的未合拢而移动穿过空腔，从而1)向临床医生提供击发触发器已完成击发冲程的强化的可听指示，以及2)向临床医生提供在击发冲程已完成后砧座组件已经移回至未合拢或分隔位置的强化的可听指示。当手术钉合装置的砧座组件的砧座头部从套筒组件分隔开足够的距离以允许砧座头部移动到倾斜的低剖面位置时，可以保证砧座组件已经移回至未合拢或分隔位置的指示。
图1示出当前公开的手术钉合装置10的一个实施例。简言之，手术钉合装置10包含手柄组件12、中心主体或细长部分14、壳体或套筒组件16以及砧座组件18。虽然中心主体部分14示出为略微弯曲，但应理解，中心主体部分14可以是笔直的或具有适合于执行所需外科手术的任何弯曲度。
除另有说明外，钉合器10的部件一般都是由包含聚碳酸酯在内的热塑性塑料和包含不锈钢和铝在内的金属制成。形成具体部件所选的具体材料将取决于具体部件的强度要求并取决于所述部件是可重复使用的部件还是一次性使用的部件。例如，砧座组件18可以由不锈钢等金属形成，而手柄组件12的各部分可以由聚碳酸酯等热塑性塑料形成。另外，手柄组件12可以由耐高压灭菌的材料形成以允许重复使用，而套筒组件的各部分可以由热塑性塑料形成以方便处理。设想，可以使用具有适合于手术用的必备强度要求的其它材料来形成手术钉合器10的部件。
手柄组件12包含固定手柄22、击发触发器组件24、合拢旋钮26、指示器组件28以及锁定机构30。合拢旋钮26用于使驱动螺钉40(图4)缩回和前移，从而使砧座组件18相对于套筒组件16在分隔位置与合拢位置之间前移或缩回。锁定机构30用于防止击发触发器24的启动，直到砧座组件18和套筒组件16已经合拢到击发区中为止，击发区即砧座与套筒组件之间的组织间隙减小到能适合形成钉的程度的位置。击发触发器组件24用于启动推进器104(图1A)，在套筒组件16和砧座组件18已经分别在击发区内合拢之后从套筒组件16射出钉。
上文标识的手柄组件12的每一个部件基本上如2007年12月4日发布的标题为“具有视觉指示器的手术钉合装置(Surgical Stapling Device With Visual Indicator)”的第7,303,106号美国专利(“'106专利”)中所描述。'106专利以全文引用的方式并入本文中。本文中将仅更详细地描述手柄组件12的那些与当前公开的可听指示器机构相互作用的部件。
砧座组件18包含砧座轴或中心杆32和砧座头部34。在实施例中，砧座头部34以枢转方式安装到砧座轴32的远端，使得砧座头部34可以在手术非倾斜位置与倾斜位置(未示出)之间移动。'106专利中详细地描述了此类砧座组件18。
套筒组件16紧固到手术钉合器10的中心主体部分14的远端并且包含壳体或外壳38。外壳38支撑回推器(未示出)、刀具(未示出)、以及支撑钉的一个或多个环形阵列的钉引导件43(图1)。'106专利中也提供了套筒组件16的部件的详细内容。
还参考图1A，砧座组件18(图1)支撑在合拢机构(未整体示出)的远端上，所述合拢机构包含旋转旋钮26、砧座保持器36(图1)和驱动螺钉40(图1A)。旋转旋钮26可操作地连接到驱动螺钉40的近端，并且砧座保持器36可操作地连接到驱动螺钉40的远端，使得旋转旋钮26的启动能使驱动螺钉40在固定手柄22内缩回和前移，从而使砧座组件18相对于套筒组件16在分隔位置与合拢位置之间移动。螺钉止动器50固定地支撑在驱动螺钉40上，并且包含沿着固定手柄22内界定的支架86(图5)移动的对接件92，如下文进一步详细描述。'106专利中提供了合拢机构的详细内容。
还参考图1B和2，手柄组件12的固定手柄22支撑可听指示器机构60，所述可听指示器机构包含发声器62(图2)和偏置构件64，例如螺旋弹簧。在实施例中，如图1A和2中所示，发声器62具有T形并且包含水平部分66和竖直部分68。发声器62的水平部分66的近端66a界定开口70(图2)，所述开口有助于将发声器62连接到偏置构件64的远端72。偏置构件64的近端74固定地紧固到固定手柄22的壁，使得偏置构件64处于张力中并且发声器62被偏置构件64向近侧牵引。
发声器62的竖直部分68包含支撑销78的上部部分76和支撑突片82的下部部分80。上部部分76延伸穿过固定手柄22的支架86中界定的插槽84(图5)，并且具有在远端方向上向下成角的表面88，如下文进一步详细描述。销78收纳于固定手柄22的内侧壁93(图1B)中形成的切口90内。切口90界定上通道部分94和下空腔部分96，如图1A中所示。上通道部分94从下空腔部分96的近端壁98(图1B)向近侧延伸。在发声器62处于第一位置时钉合装置10的预击发条件下，销78置于切口90的下空腔部分96中，其中销78通过偏置构件64抵靠下空腔部分96的近端壁98推动。在实施例中，近端壁98在远端方向上朝上成角度，使得偏置构件64沿着近端壁98向近侧推动销78到切口90的下部角中。
参考图3-6，如上文所论述，螺钉止动器50通过定位螺钉40a(图4)固定地紧固到驱动螺钉40，并且包含对接件92，所述对接件定位成沿着固定手柄22的支架86平移。在一个实施例中，对接件92包含从螺钉止动器50的主体朝外延伸的一对翼形部92a(图5)中的一个。翼形部92a中的一个定位成越过固定手柄22的支架86中的插槽84(图5)并且与发声器62的成角表面88接合。当砧座组件18相对于套筒组件16处于未合拢或分隔位置(图1)时，螺钉止动器50的翼形部92a位于插槽84远侧。当驱动螺钉40在固定手柄22内缩回以使砧座组件18相对于套筒组件16朝向合拢位置移动时，螺钉止动器50的翼形部92a在插槽84和发声器62的成角表面88上向近侧移动，使得发声器62的销78保持位于抵靠切口90(图6)的下部角中的近端壁98。因为发声器62的表面88向下成角度，在螺钉止动器50的近端移动期间翼形部92a与发声器62的表面88之间的略微接合不会防碍翼形部92a在发声器62上的近端移动。
击发组件24包含击发触发器100和轭或连杆102。击发触发器100的远端通过销104a以枢转方式连接到推进器104，并且击发触发器100的中心部分通过销102a以枢转方式连接到连杆102的远端。连杆102的近端包含销106，所述销偏置为当驱动螺钉40处于缩回位置(图4)时与形成于螺钉止动器50上的对接件108接合，使得当击发触发器100朝向固定手柄22枢转通过击发冲程时，连杆102从成角定向枢转到与钉合装置10的纵向轴线对准的定向，从而将推进器104向远侧驱动并从套筒组件16射出钉。'106专利中详细地描述了此结构。
参考图7，连杆102包含突片110，所述突片位于发声器62的突片82之下。当击发触发器100移动通过击发冲程并且连杆102在由箭头“A”指示的方向上朝向发声器62向上枢转时，击发组件的连杆102的突片110接合发声器62的突片82，并且将发声器62在由箭头“B”指示的方向上从其第一位置朝上提升。当发声器62朝向第二位置向上提升时，从发声器62的侧壁延伸的销78沿着近端壁98在切口90的下空腔部分96内朝向切口90的上通道部分94向上移动。如上文所论述，近端壁98向远侧成角度，使得当销78沿着壁98朝上移动时，偏置构件64中的张力增加。
参考图8，当击发触发器100接近完成击发冲程时，发声器62从其中销78定位成邻近于近端壁98的上端的第二位置朝向其中销78越过近端壁98的上端并移至切口90的上通道部分94的近端的第三位置移动。如上文所描述，上通道部分94从下空腔部分96向近侧延伸。因而，当销78移至与切口90的上通道部分94对准时，处于张力中的偏置构件64将发声器62在由箭头“C”指示的方向上在固定外壳22内向近侧牵引到第三位置，使得销78在切口90的上通道部分94内向近侧移动并且猛击上通道部分94的端壁112。销78与端壁112之间的接合能向临床医生提供击发冲程已完成并且可以释放击发触发器100的强化的可听指示。在销78收纳于切口90的上通道部分94中的情况下，发声器62保持在升高位置，使得发声器62的上部部分76更远离插槽84延伸到高于支架86的位置。
参考图8A，在钉合装置10击发之后，通过致动旋转旋钮26(图1)使砧座组件18朝向未合拢位置(图1)移动，从而使驱动螺钉40在由箭头“D”指示的方向上在固定手柄22内前移。当驱动螺钉40在固定手柄22内前移时，螺钉止动器50的翼形部92a沿着支架86(图5)移动并且接合发声器62的上部部分76，从而随螺钉止动器50一起将发声器62在由箭头“E”指示的方向上相对偏置构件64的偏置向远侧牵引。
参考图9和10，当螺钉止动器50继续在由箭头“D”指示的方向上在固定手柄22内向远侧移动时，销78移出上通道部分94并且沿着近端壁98进入下空腔部分96，从而使发声器62在由箭头“F”指示的方向上倾斜到降低位置，其中销78搁置在下部空腔96的底壁150上。在降低位置中，发声器62的上端保持与螺钉止动器50的翼形部92a接合，使得螺钉止动器50向远侧的移动继续向远侧牵引发声器62，直到沿着底壁150将销78牵引到与切口90的下部空腔96的远端接合(图10)。
参考图11和12，当发声器62的销78接合切口90的下部空腔96的远端壁时，阻止发声器62的进一步远端移动。当螺钉止动器50进一步向远侧移动时，翼形部92a与发声器62的上端之间的接合将使发声器62围绕销78在由图11中箭头“G”指示的方向上朝下枢转，从而使螺钉止动器50的翼形部92a能越过发声器62。当翼形部92a越过发声器62时，处于张力中的偏置构件64将发声器62在由图12中箭头“H”指示的方向上向近侧牵引，使得销78猛击切口90的下空腔部分96的近端壁98。应注意，在一些实施例中，当砧座头部34与套筒组件16分隔开足够的距离以允许砧座组件18的砧座头部34倾斜到低剖面位置时，螺钉止动器50的翼形部92a定位成在合拢位置越过发声器62。'106专利公开了一种包含可从操作位置移动到低剖面倾斜位置的砧座头部的砧座组件。
所属领域的技术人员将理解，在本文中具体地描述且在附图中所说明的装置和方法是非限制性的示范性实施例。据设想，在不脱离本公开的范围的情况下，结合一个示范性实施例说明或描述的元件和特征可与另一实施例的元件和特征组合。此外，所属领域的技术人员将理解本公开的基于上文所描述的实施例的另外的特征和优点。因此，本公开不应受具体展示并描述的内容限制，而是由所附权利要求书指示。
