具体实施方式
参照附图详细描述本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相应的元件。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。
参照图1和图2，根据本公开的实施例的包括闩锁机构的总体示出为接合器组件100的接合器组件是总体示出为手术器械1的动力手持式机电器械的部件。如图1所示，手术器械1包括致动组件10，致动组件10构造成用于与接合器组件100选择性连接，并且依次的，接合器组件100构造成用于与延伸组件20选择性连接。延伸组件20构造成用于与例如工具组件30的工具组件或末端执行器选择性连接，在示例性实施例中，工具组件可以包括装载单元40和砧座组件50，用于将环形阵列的吻合钉(未示出)施加至组织(未示出)。关于示例性致动组件的详细描述，请参照共有美国专利申请公开第2012/0253329号，其内容整体通过引用合并于此。
虽然本公开的闩锁机构将显示和描述为关于接合器组件100，可以设想，本处公开的闩锁机构可适合于与具有另一种构造的接合器组件一起使用和/或闩锁机构可直接并入致动组件。关于示例性接合器组件和示例性延伸组件的详细说明，请参考2014年10月21日提交的共有美国临时专利申请第62/066,518号(“'518申请”)，其内容整体通过引用合并于此。
现在参照图2和图3，接合器组件100包括手柄组件110和从手柄组件110向远侧延伸的细长主体部120。特别参照图3，手柄组件110包括基座或芯112以及围绕基座112被可旋转地支撑的旋转手柄114。基座112包括构造为通过联接组件116(图2)选择性地紧固至致动组件10(图1)的大致圆筒形主体。一个或多个驱动组件(未示出)延伸穿过接合器组件100的基座112和细长主体部120(图2)，用于将来自致动组件10(图1)的动力传递到末端执行器30(图1)以用于实现末端执行器30的致动。关于包括示例性联接组件和示例性驱动组件的示例性接合器组件的详细描述，请参考'518申请，其内容在先前并入本文。
继续参照图2和图3，旋转手柄114包括截头圆锥体，所述截头圆锥体具有构造为由用户可操作地接合的多个脊118。细长主体部120(图2)固定地紧固至旋转手柄114，使得旋转手柄114的围绕接合器组件100的纵向轴线“X”的旋转引起细长主体部120的围绕纵向轴线“X”的旋转。以这种方式，紧固至接合器组件100的细长主体部120的例如工具组件30(图1)的末端执行器，或者紧固至紧固至接合器组件100的细长主体部120的例如延伸组件20(图1)的延伸组件的末端执行器是可以独立于附接了接合器组件100的致动组件10(图1)的移动而旋转的。
继续参照图3，接合器组件100包括可操作地安装到旋转手柄114的闩锁机构130，用于将旋转手柄114相对于基座112围绕纵向轴线“X”紧固在固定方位。闩锁机构130包括闩锁构件或按钮132、从闩锁构件132径向向内延伸的柱构件134、以及与闩锁构件132可操作地接合的偏置构件，即，压缩弹簧136。
现在参照图3至图5，闩锁机构130的闩锁构件132可滑动地布置在旋转手柄114中的凹槽115(图3)内并且构造为由用户可操作地接合。闩锁构件132能够在远侧位置(图4)和近侧位置(图5)之间移动。压缩弹簧136(图3)将闩锁构件132偏置到远侧位置。当闩锁构件132在远侧位置时，闩锁机构130处于锁定位置，即，旋转手柄114相对于基座112可旋转地紧固。当闩锁构件132移动到近侧位置时，闩锁机构130处于解锁位置，即，旋转手柄114能够相对于基座112旋转。
继续参照图4和图5，手柄组件110的基座112限定了围绕基座112周向延伸的狭槽111。如图所示，狭槽111围绕基座112延伸大约八十度(80°)，允许旋转手柄114相对于基座112的大约八十度(80°)的旋转。可以设想，狭槽111可延伸大于或小于八十度(80°)，并且在实施例中，完全围绕基座112的圆周。多个槽口113从狭槽111向远侧延伸。如将在下面进一步详细描述的那样，槽口113构造成当闩锁构件132处于远侧位置时选择性地接收闩锁机构130的柱构件134。如图所示，槽口113关于狭槽111的长度等距隔开。以这种方式，旋转手柄114可以相对于基座112紧固在旋转的相等的间隔处。可以设想，槽口113之间的间隔可以变化。在一些实施例中，基座112可仅包括两个槽口113，一个形成为邻近狭槽111的第一端，并且第二槽口113形成为邻近狭槽111的第二端。
虽然示出通过使闩锁构件132沿近侧方向移动以使柱构件134从槽口113内缩回而使闩锁机构130可操作，即，解锁闩锁机构130，但是可以设想，为了便于使用和/或用户偏好，闩锁机构130可构造成使得闩锁构件132沿远侧方向移动以解锁闩锁机构130。这样的布置将需要基座112中的槽口113从狭槽111向远侧延伸。
接合器组件100的基座112可以限定维修槽(未示出)，以在旋转手柄114相对于基座112旋转时容纳布置成线圈或线轴的电缆(未示出)。更具体地，维修槽允许电缆在旋转手柄114相对于基座112旋转期间膨胀和收缩。
参照图6和图7，根据本公开的替代实施例的闩锁机构总体示出为闩锁机构230。闩锁机构230构造成使得旋转手柄(未示出)可相对于基座212旋转大约一百八十度(180°)。闩锁机构230基本上类似于如上所述的闩锁机构130，因此仅详细描述关于其间的差别。闩锁机构230可与基座212操作。基座212限定狭槽211和第一槽口213和第二槽口(未示出)。
闩锁机构230包括闩锁构件232以及从闩锁构件232径向向内延伸的柱构件234。如图6所示，当闩锁机构230的闩锁构件232处于远侧位置时，闩锁机构230的柱构件234接收在基座212的第一槽口213中，从而将旋转手柄(未示出)相对于基座212锁定。转向图7，闩锁构件的如箭头“B”所指示的近侧移动使柱构件234从第一槽口213内移动，从而解锁旋转手柄(未示出)并允许旋转手柄相对于基座212的旋转。一旦旋转手柄已经充分旋转从而使得闩锁机构230的柱构件234不再与第一槽口213对准时，闩锁构件232可释放。旋转手柄然后可以继续相对于基座212旋转，直到闩锁机构230的柱构件234与第二槽口(未示出)对准且偏置构件(未示出)将柱构件234在第二槽口内偏置。可以提供听觉和/或触觉指示以提示用户闩锁机构230处于锁定位置(图6)。
如图所示，基座212包括滑环(slip ring)240，滑环240用于适应电力在致动组件10(图1)和从旋转手柄(未示出)延伸的细长主体部(未示出)之间通过基座212传递。滑环240可以是任何合适的市售滑环。滑环240使旋转手柄能够相对于基座212旋转一百八十度(180°)。
现在参照图8和图9，根据本公开的闩锁机构的另一个实施例总体表示为闩锁机构330。闩锁机构330包括闩锁构件332、从闩锁构件332延伸的柱或锁定构件334、以及用于将闩锁机构330偏置到锁定位置(图8)的偏置构件，即，压缩弹簧336。
继续参照图8和图9，基座312限定至少部分地围绕基座312周向延伸的狭槽311。多个槽口313形成在从狭槽311向近侧延伸的基座312中。多个槽口313可以等间隔地围绕狭槽311。虽然未示出，但是可以想到，狭槽311可完全地围绕基座312的圆周延伸。
当闩锁机构330处于锁定位置(图8)时，闩锁机构330的锁定构件334的与闩锁构件332相反的端部334a接收在多个槽口313中的一个内，以防止旋转手柄(未示出)相对于基座312的移动。闩锁构件332的如图9箭头“C”所指示的近侧移动引起锁定构件334围绕枢转构件338枢转，从而使锁定构件334的端部334a从槽口313内移动并与狭槽311对准。以这种方式，闩锁机构330移动到解锁位置(图9)从而旋转手柄(未示出)可相对于基座312旋转。闩锁构件332的释放允许闩锁机构330返回到锁定位置(图8)，从而将旋转手柄相对于基座312紧固。
虽然示出通过使闩锁构件332沿近侧方向移动而使闩锁机构330可操作以解锁闩锁机构330，但是可以设想，为了便于使用和/或用户偏好，闩锁机构330可构造成使得闩锁构件332沿远侧方向移动以解锁闩锁机构330。这样的布置将需要基座312中的多个槽口313从狭槽311向远侧延伸。
现在参照图10和图11，根据本公开的闩锁机构的另一个实施例总体表示为闩锁机构430。闩锁机构430包括闩锁构件432、小齿轮434和齿条或锁定构件436。例如压缩弹簧438的偏置构件围绕闩锁构件432被接收以径向向外偏置闩锁构件432。
闩锁机构430的闩锁构件432包括构造成用于由用户可操作地接合的第一部432a和具有多个齿433的第二部432b。小齿轮434包括形成为围绕小齿轮434的圆周的多个齿435。齿条构件436包括具有多个齿437的第一部436a和构造为与基座410可操作地接合的第二部436b。闩锁构件432和齿条构件436中的每个相对于基座410径向移动。
继续参照图10和图11，闩锁构件432的多个齿433可操作地接合小齿轮434的多个齿435。类似地，齿条构件436的多个齿437可操作地接合小齿轮434的多个齿435。以这种方式，并且如图11中的箭头“E”和“F”所示的，闩锁构件432和齿条构件436沿相反方向移动。更具体地，当闩锁构件432被下压时，即，径向向内或朝向基座410移动时，齿条构件436脱离基座410，即，径向向外或远离基座410移动。
基座410限定了围绕基座410的圆周的至少一部分分隔开的多个槽口413。多个槽口413可以以相等或不等的间隔分隔开。多个槽口413定位成当闩锁机构430处于锁定位置(图10)时接收齿条构件436的第二部436b。基座410可限定围绕基座410的圆周延伸且将多个槽口413互连的狭槽(未示出)，以限制齿条构件436需要径向移动的距离，其中，所述径向移动使齿条构件436从基座410脱离，即，解锁闩锁机构430，从而允许旋转手柄(未示出)相对于基座410的旋转。
现在参照图10，当闩锁机构430处于锁定位置时，齿条构件436的第二部436b被接收在基座410的多个槽口413中的一个内。压缩弹簧438的抵靠闩锁构件432的偏置将闩锁构件432保持在径向向外的位置，而这通过小齿轮434的操作将齿条构件436保持在径向向内的位置。以这种方式，包括闩锁机构430的手柄组件(未示出)相对于基座410可旋转地锁定。
转到图11，当闩锁机构430的闩锁构件432被下压时，即，如箭头“E”所指示的移动到径向向内的位置，小齿轮434的操作使齿条构件436如箭头“F”所指示的径向向外移动，以将齿条构件436的第二部436b从多个槽口413中的一个内缩回。一旦齿条构件436的第二部436b从基座410脱离，旋转手柄(未示出)能够相对于基座410旋转。
锁定机构430的闩锁构件432的释放引起齿条构件436返回到径向向内位置(由于压缩弹簧438的偏置力)，从而锁定闩锁机构430。闩锁机构430可包括用于指示用户闩锁机构430处于锁定位置(图10)的听觉和/或触觉指示器。听觉和/或触觉指示器可以代替地或还指示用户闩锁机构430处于解锁位置(图11)。
现在参照图12和图13，根据本公开的闩锁机构的又一个实施例总体表示为闩锁机构530。闩锁机构530包括闩锁构件532、连杆构件534以及锁定构件536。如图所示，例如扭簧538的偏置构件与连杆构件534接合以沿顺时针方向偏置连杆构件534，以将闩锁机构530保持在锁定位置(图12)。
闩锁机构530的闩锁构件532构造为由用户可操作地接合，并且包括从其向外延伸且用于与连杆构件534接合的销533。连杆构件534能围绕枢转销534a枢转，并且限定第一狭槽535a和第二狭槽535b。锁定构件536包括从其向外延伸且用于与连杆构件534接合的销537。锁定构件536构造为用于与基座510可操作的接合。闩锁构件532和锁定构件536中的每个相对于基座510径向移动。
继续参照图12和图13，闩锁构件532的销533被接收在连杆构件534的第一狭槽535a中，并且锁定构件536的销537被接收在连杆构件534的第二狭槽535b内。闩锁构件532和锁定构件536与连杆构件534的接合使得闩锁构件532和锁定构件536沿相反方向移动，如图13所示的箭头“G”和“H”所指示的。更具体地，当闩锁构件532被下压时，即，径向向内或朝向基座510移动时，锁定构件536脱离基座510，即，径向向外或远离基座510移动。
基座510限定了围绕基座510的圆周的至少一部分分隔开的多个槽口513。多个槽口513可以以相等或不等的间隔分隔开，并且定位成当闩锁机构530处于锁定位置(图12)时接收锁定构件536。基座510可限定围绕基座510的圆周延伸且将多个槽口513互连的狭槽(未示出)，以限制锁定构件536需要径向移动的距离，其中所述径向移动使锁定构件536从基座510脱离，即，解锁闩锁机构530，从而允许旋转手柄(未示出)相对于基座510的旋转。
现在特别参照图12，当闩锁机构530处于锁定位置时，锁定构件536被接收在基座510的多个槽口513中的一个内。扭簧538对连杆构件534的偏置将闩锁构件532保持在径向向外的位置并且将锁定构件536保持在径向向内的位置。以这种方式，基座510相对于手柄组件(未示出)可旋转地锁定。
转到图13，当闩锁机构530的闩锁构件532被下压时，即，如由箭头“G”所指示的移动到径向向内的位置，连杆构件534的操作使锁定构件536如由箭头“H”所指示的径向向外移动，从而使锁定构件536从多个槽口513中的一个内缩回。一旦锁定构件536从基座510脱离，旋转手柄(未示出)相对于基座510是可旋转的。
闩锁机构530的闩锁构件532的释放引起锁定构件536返回到径向向内位置(由于扭簧538的偏置力)，从而锁定闩锁机构530。闩锁机构530可包括用于指示用户闩锁机构530处于锁定位置(图12)的听觉和/或触觉指示器。听觉和/或触觉指示器也可以或代替地指示用户闩锁机构530处于解锁位置(图13)。
考虑到强度、耐用性、耐磨性、重量、耐腐蚀性、制造的容易、制造的成本等，本文描述的任何部件均可由金属、塑料、树脂、复合材料或类似物制造。
本领域技术人员将理解的是，本文具体描述且在附图中图示出的装置和方法是非限制性示例实施例。可以设想，与一个示范实施例相关地图示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。同样，本领域的技术人员将会基于上述实施例而理解本公开的进一步的特征和优点。因此，除了由所附权利要求指出的，本公开不被已经具体示出和描述的内容限制。
