具体实施方式
参照附图详细描述本处公开的用于手术装置和/或手柄组件的接合器组件的实施例，在附图中，在几幅视图的每个中，相同附图标记指代相同或对应的元件。如本文所用的，术语“远侧”指的是接合器组件或者手术装置或其部件的较远离用户的部分，而术语“近侧”指的是接合器组件或者手术装置或其部件的较靠近用户的部分。
参考图1，依照本公开的实施例的接合器组件(总体示为接合器组件100)构造为用于选择性连接至动力手持机电致动器(总体示为手柄组件20)。如图1所示，接合器组件100构造为用于与手柄组件20选择性连接。例如工具组件30的工具组件或末端执行器构造为用于与接合器组件100选择性的连接，其中，在示例性实施例中，工具组件30可以包括装载单元40和砧座组件50，用于将圆形阵列的吻合钉(未示出)施加至组织(未示出)。手柄组件20、接合器组件100和工具组件30形成手术吻合装置10。虽然示出并描述为与圆形吻合装载单元一起使用，可以想到的是，本公开的接合器组件可以修改为与具有替代构造的吻合组件、和/或与非吻合末端执行器一起使用。
关于示例性手柄组件的结构和功能的详细描述，请参考共有美国专利申请公开第2012/0253329号(“'329申请”)，其全部内容通过引用合并于此。
首先参照图1至图3，接合器组件100包括：近侧部102，其构造成用于可操作地连接至手柄组件20(图1)并且由用户可操作地接合；以及远侧部104，其构造为用于可操作地连接至工具组件30(图1)以及工具组件30的放置，其中，工具组件30包括装载单元40(图1)和砧座组件50(图1)。更具体地，接合器组件100的近侧部102包括基座构件106以及可旋转地紧固至基座构件106的手柄构件108。远侧部104包括固定地紧固至手柄构件108并且从其延伸的套筒109。接合器组件100的中央纵向轴线“x”(图4)从手柄组件20(图1)的中央纵向轴线“y”(图4)偏离距离“d”(图4)。在一个实施例中，偏离距离“d”大约为0.25英寸，而在另一个实施例中，偏置距离“d”大约为0.075英寸。
接合器组件100包括布置在接合器组件100的基座构件106内的、用于可操作地连接手柄组件20的驱动轴(未示出)与接合器组件100的驱动机构118的联接组件110。联接组件110包括可旋转地支撑在接合器组件100的基座构件106内的第一、第二和第三连接套筒112、114、116。联接组件110的第一、第二和第三连接套筒112、114、116将手柄组件20(图1)的相应的第一、第二和第三驱动轴(未示出)与接合器组件100的驱动机构118的相应的第一、第二和第三驱动组件120、140、160可操作地连接。关于示例性联接组件的更详细的描述，请参考2014年10月21日提交的、序列号为62/066,518的共有美国临时专利申请，其全部内容通过引用合并于此。
现在参考图9和图10，接合器组件100的驱动机构118(图6)的第一驱动组件120包括：第一驱动轴122和第一远侧驱动轴124，其可旋转地支撑在基座构件106内；以及第一驱动螺杆126，其可旋转地支撑在第一壳体板128(图9；以虚像示出)和推力板130(图9；以虚像示出)之间。第一驱动轴122的近侧端可操作地连接至联接组件110的第一连接套筒112。第一驱动轴122的远侧端包括与其一体形成或不可旋转地支撑在其上的第一驱动齿轮122b。第一远侧驱动轴124的近侧端包括与其一体形成或不可旋转地支撑在其上的且与第一驱动齿轮122b可操作地连接的第二驱动齿轮124a。第一远侧驱动轴124的远侧端可操作地连接至第一驱动螺杆126。虽然示出为分离部件，可以想到的是，第一远侧驱动轴124和第一驱动螺杆126可以整体地形成。第一驱动螺杆126的近侧端包括与其一体形成或不可旋转地支撑在其上的齿轮突缘126a。第一驱动螺杆126的远侧端包括螺纹部126b。
第一驱动组件120的第一驱动螺杆126的齿轮突缘126a可旋转地接收在第一壳体板128(图9；以虚像示出)和推力板130(图9；以虚像示出)之间。第一轴承组件134(图5)利于第一驱动螺杆126的在第一壳体板128和推力板130之间的旋转。虽然未示出，推力板130接合接合器组件100的手柄构件108以将来自第一驱动组件120的负荷分配到手柄构件108。第一驱动螺杆126的中央纵向轴线沿着接合器组件100的中央纵向轴线“x”延伸。
如图4所示，第一驱动组件120的套管针构件132的螺纹近侧端132a关于第一驱动螺杆126的螺纹部126b被可操作地接收。第一驱动螺杆126的关于纵向轴线“x”的旋转实现套管针构件132的纵向移动。当砧座组件50(图1)紧固至套管针构件132的远侧端132b时，第一驱动螺杆126的沿第一方向的旋转引起砧座组件50的相对于装载单元40(图1)的靠近。相反地，第一驱动螺杆126的沿第二方向的旋转引起砧座组件50远离装载单元40移动。可替代地，第一驱动螺杆126可操作地连接至末端执行器(未示出)的线性或旋转致动组件(未示出)，用于实现例如夹紧组织(未示出)的第一功能的性能。在一个实施例中，推力板130可包括用于测量第一驱动组件120的操作期间的夹紧力的应变仪。通过改变第一驱动组件120的第一和第二驱动齿轮122b、124a的大小，可以改变驱动螺杆126相对于来自手柄组件20的输入的旋转的速率。
现在参考图11至图13，接合器组件100(图1)的驱动机构118(图6)的第二驱动组件140包括：第二驱动轴142和复合齿轮轴144，其可旋转地支撑在基座构件106内；以及第二驱动螺杆146，其可旋转地支撑在第一驱动螺杆126的齿轮突缘126a和第二壳体板148之间。如将在下面进一步详细描述的，当第二驱动组件140的第二驱动螺杆146经受沿近侧方向的负荷时，第二驱动螺杆146的与第一驱动组件120的第一驱动螺杆126的接合将来自第二驱动组件140的负荷分配至第一驱动组件120。这种布置平衡了接合器组件100的操作期间第一驱动组件120中经受的负荷(即，沿远侧方向的)与第二驱动组件140中经受的负荷(即，沿近侧方向的)。
第二驱动组件140的第二驱动轴142的近侧端可操作地连接至联接组件110的第二连接套筒114。第二驱动轴142的远侧端包括与其一体形成或不可旋转地支撑在其上的第一驱动齿轮142b。复合齿轮轴144的近侧端包括与其一体形成或不可旋转地支撑在其上的第二驱动齿轮144a，并且复合齿轮轴144的远侧端包括第三驱动齿轮144b。第二驱动齿轮144a与第一驱动齿轮142b可操作地连接，并且第三驱动齿轮可操作地连接至第二驱动螺杆146。如所示出的，第二驱动齿轮144a包括比第三驱动齿轮144b大的直径。以这种方式，复合齿轮轴146操作以降低输出速度并增大从手柄组件20传递到第二驱动螺杆146的输出转矩。在实施例中，第二复合齿轮轴146代替行星齿轮系统(未示出)，从而节省接合器组件100内的空间，并减少了接合器组件100的操作所需的齿轮的数量。
第二驱动螺杆146的近侧端包括与其一体形成或不可旋转地支撑在其上的且与复合齿轮轴144的第三驱动齿轮144b可操作地接合的齿轮突缘146a。第二驱动螺杆146的远侧端包括螺纹部146b。第二驱动组件140的第二驱动螺杆146关于第一驱动组件120的第一驱动螺杆126的螺纹部126b被接收并且适应第一驱动组件120的套管针构件132的关于第一驱动螺杆126的螺纹部126a的接收。
第二驱动组件140的第二驱动螺杆146的齿轮突缘146a可旋转地接收在第一驱动螺杆126的齿轮突缘126a和第二壳体板148之间。第二轴承组件154利于第二驱动螺杆146在第一驱动螺杆126的齿轮突缘126a和第二壳体板148之间的旋转。第二驱动螺杆146的中央纵向轴线沿着接合器组件100(图4)的中央纵向轴线“x”延伸。
第二驱动螺杆146的螺纹部146b可操作地连接至工具组件30(图1)或其它适当的末端执行器的装载单元40(图1)的线性或旋转致动组件(未示出)，用于实现例如吻合组织(未示出)的第二功能的性能。
现在参考图15，接合器组件100的驱动机构118的第三驱动组件160包括：第三驱动轴162和复合齿轮轴164，其可旋转地支撑在基座构件106内；以及第三驱动螺杆166，其可旋转地支撑在第二驱动螺杆146的齿轮突缘146a和第三壳体板168之间。如将在下面进一步详细描述的，当第三驱动组件160的第三驱动螺杆166经受沿近侧方向的负荷时，第三驱动组件160的第三驱动螺杆166的与第二驱动组件140的第二驱动螺杆146的接合，以及第二驱动组件140的第二驱动螺杆146的与第一驱动组件120的第一驱动螺杆126的接合，将来自第二和第三驱动组件140、160的负荷分配至第一驱动组件120。这种布置平衡了接合器组件100的操作期间第一驱动组件120中经受的负荷(即，沿远侧方向的)与第二和第三驱动组件140、160中经受的负荷(即，沿近侧方向的)。
第三驱动组件160的第三驱动轴162的近侧端可操作地接合联接组件110的第三连接套筒116。第三驱动轴162的远侧端包括与其一体形成或不可旋转地支撑在其上的第一驱动齿轮162b。复合齿轮轴164的近侧端包括与其一体形成或不可旋转地支撑在其上的第二驱动齿轮164a，并且复合齿轮轴164的远侧端包括第三驱动齿轮164b。第二驱动齿轮164a与第一驱动齿轮162b可操作地连接，并且第三驱动齿轮可操作地连接至第二驱动螺杆166。如所示出的，第二驱动齿轮164a包括比第三驱动齿轮164b大的直径。以这种方式，复合齿轮轴164操作以降低输出速度，并增加从手柄组件20传递到第三驱动螺杆166的输出转矩。在实施例中，第三复合齿轮轴164代替在前面的实施例中使用行星齿轮系统(未示出)，从而节省了接合器组件100内的空间，并减少了接合器组件100的操作所需的齿轮的数量。
第三驱动螺杆166的近侧端包括与其一体形成或不可旋转地支撑在其上的且与复合齿轮轴164的第三驱动齿轮164b可操作地接合的齿轮突缘166a。第三驱动螺杆166的远侧端包括螺纹部166b。第三驱动组件160的第三驱动螺杆166关于第二驱动组件140的第二驱动螺杆146被接收在第二驱动螺杆146的齿轮突缘146a和第二驱动螺杆146的螺纹部146b之间。
第三驱动组件160的第三驱动螺杆166的齿轮突缘166a可旋转地接收在第二驱动组件140的第二驱动螺杆146的齿轮突缘146a和第三壳体板168之间。第三轴承组件174利于第三驱动组件160的第三驱动螺杆166在第二驱动组件140的第二驱动螺杆146的第二突缘146a和第三壳体板168之间的旋转。第三驱动螺杆166的中央纵向轴线沿着接合器组件100的中央纵向轴线“x”延伸。相应地，驱动机构118的第一、第二和第三驱动组件120、140、160的中央纵向轴线中的每个都沿接合器组件100的中央纵向轴线“x”(图4)延伸，即，相应的第一、第二和第三驱动组件120、140、160的第一、第二和第三驱动螺杆126、146、166是同轴的。以这种方式，附接至接合器组件100的远侧部104的末端执行器可以关于中央纵向轴线“x”旋转，以利于末端执行器的旋转定位。
第三驱动组件160的第三驱动螺杆166的螺纹部166b可操作地连接至工具组件30或(图1)其它适当的末端执行器的装载单元40(图1)的线性或旋转致动组件(未示出)，用于实现例如切割组织(未示出)的第三功能的性能。
现在将参照附图说明接合器组件100的操作。接合器组件100紧固至手柄组件20(图1)，并且工具组件30(图1)的装载单元40以传统的方式紧固至接合器组件100。在工具组件30(图1)的砧座组件50(图1)通过待吻合的组织(未示出)放置后，和/或待吻合的组织例如通过荷包式缝合线围绕砧座组件50放置后，砧座组件50紧固至接合器组件100的套管针构件132。
然后手柄组件20可致动以引起手柄组件20的第一、第二和第三驱动轴(未示出)中的任何驱动轴的单独的或同时的旋转，以实现接合器组件100的驱动机构118的相应的第一、第二和第三驱动组件120、140、160的致动。
简要参考图9和图10，在致动手柄组件20(图1)以致动第一驱动组件120期间，手柄组件20的第一驱动轴(未示出)的旋转使第一连接套筒112旋转，第一连接套筒112的旋转使第一驱动轴122旋转，第一驱动轴122的旋转使第一远侧驱动轴124旋转，以引起第一驱动螺杆126的旋转。第一驱动螺杆126的沿第一方向的旋转引起套管针构件132的沿近侧方向的纵向移动，即，缩回，并且第一驱动螺杆126的沿第二方向的旋转引起套管针构件132的沿远侧方向的纵向移动，即推进。
如上所述，驱动机构118的第一驱动组件120的致动期间，第一驱动螺杆126的齿轮突缘126a接合推力板130。接合器组件100的构造是使得推力板130仅在第一驱动组件120的致动期间经受负荷。通过这种方式，与推力板130经受来自第二和第三驱动组件140、160的额外负荷的接合器组件(未示出)相比，接合器组件100在操作期间将具有更好的分辨率(resolution)。如上所述，推力板130可包括用于测量第一驱动组件120的操作期间的夹紧力的应变仪。
转到图11至图13，在致动手柄组件20(图1)以致动第二驱动组件140期间，手柄组件20的第二驱动轴(未示出)的旋转使第二连接套筒114旋转，第二连接套筒114的旋转使第二驱动轴142旋转，第二驱动轴142的旋转使复合齿轮轴144旋转，以引起第二驱动螺杆146的旋转。第二驱动螺杆146的沿第一方向的旋转引起附接的第一推动器构件(未示出)的沿远侧方向的纵向移动，即，推进，并且，第二驱动螺杆146的沿第二方向的旋转引起附接的推动器构件(未示出)的沿近侧方向的纵向移动，即，缩回。如上所述，在驱动机构118的第二驱动组件140的致动期间，第二驱动螺杆146的齿轮突缘146a接合第一驱动螺杆126的齿轮突缘126a。
转到图14和图15，在致动手柄组件20(图1)以致动第三驱动组件160期间，手柄组件20的第三驱动轴(未示出)的旋转使第三连接套筒116旋转，第三连接套筒116的旋转使第三驱动轴162旋转，第三驱动轴162的旋转使复合齿轮轴164旋转，以使第三驱动螺杆166旋转。第三驱动螺杆166的沿第一方向的旋转引起附接的第二推动器构件(未示出)的沿远侧方向的纵向移动，即，推进，并且，第三驱动螺杆166的沿第二方向的旋转引起附接的推动器构件(未示出)的沿近侧方向的纵向移动，即，缩回。如上所述，在驱动机构118的第三驱动组件160的致动期间，第三驱动螺杆166的齿轮突缘166a接合与第一驱动螺杆126的齿轮突缘126a接合的第二驱动螺杆146的齿轮突缘146a。
接合器组件100的轴向负荷路径延伸通过相应的第一、第二和第三驱动组件120、140、160的第一、第二和第三驱动螺杆126、146、166。以这种方式，接合器组件的套筒109不经受来自第二和第三驱动组件140、160的负荷。如上所述，第一、第二和第三驱动组件120、140、160的共用中央纵向轴线允许接合器组件100的套筒109沿接合器组件100的纵向轴线“x”旋转。
考虑到强度、耐用性、耐磨性、重量、耐腐蚀性、制造的容易性、制造的成本等，本文描述的任何部件可由金属、塑料、树脂、复合材料或类似材料中的任何制造。
本领域技术人员将理解的是，本文具体描述并图示在附图中的装置和方法是非限制性示例实施例。可以想到的是，连同一个示例性实施例示出或描述的元件和特征可以在不脱离本公开的范围的情况下与另一个的元件和特征相结合。此外，本领域的技术人员将基于上述实施例理解公开的进一步的特征和优点。因此，除了由所附权利要求所指示的，本公开不由已经具体示出和描述的所限制。
