具体实施方式
本公开提供用于手术器械的闩锁组件和包括该闩锁组件的手术器械。尽管入在此详细描述的那样被并入手术施夹器中,但是本公开的闩锁组件可替代地被并入到任何合适的手术器械中。
转到图1-4,体现本公开的方面和特征的内窥镜手术施夹器通常上被显示,并由附图标记10标识。手术施夹器10通常包括手柄组件100和多个可选择性地连接到手柄组件100的细长组件200(图1-5)、300(图6)。手柄组件100被构造成在连接到其上时操作多个细长组件200、300中的每一个,并且可以被构造为可消毒的可重复使用的部件,使得手柄组件100可以在一个或多个外科手术过程中与不同的和/或附加的细长组件200、300重复使用。细长组件200、300可以根据特定目的和/或特定细长组件的构造被构造为单次使用的一次性部件、有限使用的一次性部件或可重复使用的部件。在任一种构造中,避免了对多个手柄组件100的需要,相反,外科医生仅需要选择适当的细长组件200、300,并将该细长组件连接到准备使用的手柄组件100。
手柄组件100通常包括壳体110、可操作地与壳体110相关联的致动机构120、可操作地设置在壳体110内的棘轮机构150、以及可操作地联接到壳体110的远端部分的旋转旋钮组件170。根据本公开提供的闩锁组件160也可操作地与壳体110相关联,如以下所述。壳体110支撑和/或包围手柄组件100的操作部件。致动机构120被构造成能够从附接的细长组件的末端执行器选择性地移除一个或多个手术夹(未示出)。当构造用于棘轮致动的细长组件连接到手柄组件100时,棘轮机构150能够使致动机构120的驱动杆130进行棘轮推进。闩锁组件160被构造成有利于细长组件与手柄组件100的可释放锁定接合。旋转旋钮组件170使得附接的细长组件能够相对于壳体110选择性地旋转。
另外参考图5和6,如上所述,手柄组件100被构造成与不同的细长组件一起使用,例如细长组件200(图5)和细长组件300(图6)。更具体地,把手组件100被构造用于棘轮用途,例如与细长组件200(图5)连接,以及非棘轮用途,例如与细长组件300(图6)连接。下面简要描述细长组件200,300。在2016年8月26日提交的国际专利申请公开WO/2018/035796、2016年1月18日提交的国际专利申请公开WO/2017/124217和/或2015年10月10日提交的国际专利申请公开WO/2017/059587中可以找到构造成与手柄组件100一起使用的细长组件例如细长组件200,300的更详细讨论,其全部内容通过引用合并在本文中。
参考图1-5,细长组件200被构造成用于棘轮用途,并且通常包括近端毂220、从近端毂220向远端延伸的细长轴240、朝向细长轴240的远端部分设置的末端执行器组件260、以及内部驱动组件(未示出),当细长组件200与手柄组件100接合以能够在组织周围顺序地移除至少一个手术夹(未示出)时,所述内部驱动组件(未示出)可操作地联接在手柄组件100与末端执行器组件260之间。细长组件200的末端执行器组件260可以被构造成击发类似于美国专利7,819,886或美国专利7,905,890中所示和所述的手术夹,其中每个美国专利的全部内容均通过引用合并在本文中。
细长组件200的近端毂220限定了多个分度突出件222,所述分度突出件222朝向其远端部分环形设置(参见图4)。分度突出件222被构造成可滑动地接纳在限定在旋转旋钮组件170的外旋钮172内的纵向延伸的凹槽178内,以在近端毂220插入通过其中时相对于旋转旋钮组件170旋转地固定细长组件200的近端毂220。这样,在使用中,旋转旋钮组件170的外旋钮172相对于壳体110的旋转实现了细长组件200相对于壳体110的相应旋转。
近端毂220还限定朝向其近端的环形通道224和倒角的近端边缘226。如下所述,在近端毂220插入通过旋钮组件170并插入壳体110的主体部分111时,倒角的近端边缘226在近端毂220的外表面上将闩锁组件160的杆162的接合齿180凸出,直到接合齿180设置成与环形通道224对齐,由此接合齿180落入环形凹槽224内的接合中,以将近端毂220与手柄组件100接合并因此将细长组件200与手柄组件100接合。
参见图6,细长组件300被构造成用于非棘轮用途,并且通常包括近端毂(未示出)、从近端毂向远端延伸的细长轴340、朝向细长轴340的远端部分设置的末端执行器组件360和内部驱动组件(未示出),当细长组件300与手柄组件100接合(图1)以便能够抓握和/或操纵组织、取回手术夹并且围绕组织移除手术夹时,所述内部驱动组件(未示出)可操作地联接在手柄组件100与末端执行器组件360之间。可以预期,细长组件300的末端执行器组件360可以构造成击发类似于美国专利4,834,096中所显示和所描述的手术夹,其全部内容通过引用合并在本文中。
另外参考图1-4,类似于细长组件200的近端毂220,细长组件300的近端毂(未示出)还可包括分度突出件,以在使近端毂插入通过其中时相对于旋转旋钮组件170旋转地固定细长组件300和/或环形通道和倒角的近端边缘,从而有利于闩锁组件160的杆162的接合齿180与细长组件300接合,以使细长组件与手柄组件100接合。
尽管上面详细描述了分别构造用于棘轮用途和非棘轮用途的示例性内细长组件200、300,但是可以预期,用于执行各种不同的外科手术任务和/或具有适合于棘轮用途或非棘轮用途的各种不同构造的各种其他细长组件同样可以与手柄组件100一起使用。
回到图1-4,手柄组件100的壳体110可以由第一壳体半部和第二壳体半部110a、110b(图8)形成,所述第一壳体半部和第二壳体半部配合以限定主体部分111和从主体部分111悬垂的固定手柄部分112。壳体110的主体部分111包括在主体部分111内横向延伸的内部枢轴柱114以及限定穿过其中的远端开口118的远端鼻部116。细长组件的近端毂的近端部分,例如细长组件200的近端毂220或细长组件300(图6)的近端毂(未示出),被构造成当细长组件与手柄组件100接合时至少部分地延伸通过壳体110的远端鼻部116的远端开口118。
致动机构120由壳体110可操作地支撑,并且包括触发器122、连杆126、驱动杆130和偏置构件140。触发器122包括抓握部分123、中间枢轴部分124和近端延伸件125。触发器122的抓握部分123以相对于外壳110的固定手柄部分112相对的关系从外壳110的主体部分111向下延伸。抓握部分123被构造为有利于触发器122的抓握和操纵。触发器122的中间枢轴部分124至少部分地设置在壳体110内,并且限定枢轴孔,所述枢轴孔构造成接纳壳体110的枢轴柱114,以使得触发器122能够围绕枢轴柱114并相对于壳体110例如在未致动位置和致动位置之间枢转,在所述未致动位置中,触发器122的抓握部分123相对于固定手柄部分112间隔开,以及在所述致动位置中,触发器122的抓握部分123相对于固定手柄部分112接近。
与触发器122的抓握部分123相比,触发器122的近端延伸件125设置在中间枢轴部分124的相对侧上,并因此设置在枢轴柱114上。这样,枢转抓握部分123以沿一个方向,例如朝向固定手柄部分112向近端旋转,使近端延伸件125枢转,以沿着相反方向,例如向远端旋转。触发器122的近端延伸件125可枢转地联接到连杆126的近端。偏置构件140固定在任一端,并在触发器122的近端延伸部分125与设置在壳体110的固定手柄部分112内的支撑件(未示出)之间延伸。使抓握部分123朝向致动位置的枢转使得在其中存储能量的偏置构件140伸长,使得在释放抓握部分123时,抓握部分123在偏置构件140的偏置下朝向未致动位置返回。尽管示出为延伸螺旋弹簧,但是偏置构件140可以限定用于将触发器122的抓握部分123朝向未致动位置偏置的任何合适的构造。
如上所述,连杆126在其近端处联接到触发器122的近端延伸件125。连杆126也在其远端可枢转地连接到驱动杆130的近端。由于这种构造,触发器122的抓握部分123朝向致动位置的枢转朝向远端推动触发器122的近端延伸部分125,所述近端延伸部分125进而向远端推动连杆126,从而进而向远端推动驱动杆130。
响应于触发器122的致动,驱动杆130可滑动通过壳体110的主体部分111,以推动驱动杆130的远端部分132与细长组件的内驱动组件(未示出)的近端致动器接触,例如,细长组件200或细长组件300(图6)与手柄组件100接合,以击发支撑在细长组件的末端执行器组件上的手术夹。更具体地,驱动杆130可从对应于触发器122的抓握部分123的未致动位置的未致动的近端位置滑动到对应于触发器122的抓握部分123的致动位置的致动的远端位置,以便向远端推动细长组件的内部驱动组件(未示出)的近端致动器,从而击发支撑在细长组件的末端执行器组件处的手术夹。
驱动杆130还可包括棘轮齿条134,所述棘轮齿条134沿其下侧表面的至少一部分延伸。棘轮齿条134被构造成选择性地与棘轮机构150连接,以使驱动杆130能够在棘轮状态或非棘轮状态下前进。棘轮齿条134和棘轮机构150可以类似于例如国际专利申请公开WO/2018/035796或国际专利申请公开WO/2017/124217中所描述的那样构造,每个申请均都通过引用合并在本文中。
继续参考图1-4,旋转旋钮组件170可旋转地连接到壳体110的主体部分111的远端鼻部116,并且构造成接纳细长组件的近端毂,例如细长组件200的近端毂220,近端毂例如经由在凹槽178内接纳分度突出件222(参见图2和4)以与其固定旋转接合的方式连接到手柄组件100,以使得当旋转旋钮组件170的外旋钮172相对于壳体旋转时,细长组件200能够相对于壳体110选择性地旋转。
现在参考图1-4、7和8,本公开的闩锁组件160包括杆162、枢轴销164和偏置构件166。杆162至少部分地设置在限定的切口113内,而没有手柄组件100的壳体110,以便能够对其进行手动操作。更具体地,切口113通过分别限定在第一和第二壳体半部110a、110b内的第一和第二切口部分113a、113b的配合形成,所述壳体半部配合以限定壳体110(见图8)。
另外参考图9,杆162限定远端接合部163a、中间部163b和近端可操纵部163c。杆162的远端接合部163a包括从其延伸的接合齿180。接合齿180被构造成接合插入手柄组件100中的细长组件,例如细长组件200。更具体地,如上文关于细长组件200所述,例如,在将细长组件200的近端毂220插入手柄组件100中时,接合齿180被构造成在近端毂220的倒角的近端边缘226上并以在环形通道224内接合的方式凸出,从而将细长组件200锁定成与手柄组件100接合。
具体参考图7,闩锁组件160的枢轴销164将杆162的中间部分163b与手柄组件100的壳体110可枢转地联接,使得杆162的近端操纵部163c沿第一方向到壳体110(朝向杆162的脱离位置)中的推动将杆162的远端接合部分163a沿相反的第二方向与细长组件200的近端毂220的环形通道224脱离接合。偏置构件166被构造为扭转弹簧,所述扭转弹簧具有围绕枢轴销164设置的主体167a以及设置在壳体110与杆162的近端操纵部163c之间的第一腿167b和第二腿167b的,以远离壳体110朝向杆162的脱离位置偏置杆162的近端操纵部163c,从而朝向接合位置偏置远端接合部分163a。然而,也可以考虑偏置构件166的其他合适的构造。
结合图1-4参考图7-11,杆162的近端操作部163C可被选择性地压下到壳体110的切口113中,如图3和图4所示,克服偏置构件166的偏置,以从接合位置(图1和2;杆162的脱离位置)朝向脱离位置(图3和4;杆162的脱离位置)推动远端接合部163a,从而从细长组件200的近端毂220的环形通道224脱离接合齿180,并使细长组件200能够从手柄组件100撤出。
杆162的近端操纵部163c,更具体地,包括外表面168a,侧壁168b,其从外表面168a在相对于其大致垂直的方向上悬垂并且围绕其外周的至少一部分设置,以及唇缘168c,其在相对于侧壁168b大致垂直的方向从侧壁168b的自由端(与连接到外表面168a的侧壁168b的端部相对)延伸,以便限定从侧壁168b向外延伸的搁架168d。搁架168d沿侧面并围绕侧壁168b的近端延伸。杆162的中间部分163b从侧壁168b的远端处的侧壁168b的自由端向远侧延伸。如上所用,“大致”考虑了材料和制造公差。
如图1、7和8所示,杆162的近端操纵部163c的外表面168a在杆162的接合位置中基本上互补并构造成基本上完全占据壳体110的切口113。如上所用,“基本上”考虑了壳半部110a、110b和杆162的制造和材料公差,其可能导致外表面168a没有完全占据和/或不完全与壳体110的切口113互补。实际上,为了确保外表面168a对于切口113而言不是太大(或者切口113对于外表面168a而言不是太小)(这将使这些部件不相容并且因此不可用),杆162和/或壳半部110a、110b考虑到其公差进行制造,使得即使在最大公差变化时,外表面168a也能够装配在切口113内。结果,通常情况是外表面168a不完全占据和/或不完全与壳体110的切口113互补。
在实施例中,壳半部110a、110b通过注射成型由聚合物材料形成,而杆162由金属通过金属注射成型(MIM)形成,但是也可以考虑其他材料和/或制造方法。上面详述的公差考虑因素在使用不同材料和/或制造方法和/或使用不太精确的制造方法的情况下特别相关,以确保公差不会“叠加”以使组件彼此不相容。
继续参考图1、7和8,杆162的近端操纵部163c的外表面168a在杆162的接合位置进一步构造成基本上符合围绕切口113的壳体110的外表面轮廓,以便最小化沿着壳体110的外表面和杆162的近端操纵部163c的外表面168a的变化。外表面168a可以另外限定凹坑168e,其构造成接收使用者的手指以便于将杆162的近端操纵部163c从接合位置压下到脱离位置。
还参考图9,杆162的近端操纵部163c的搁架168d,由其唇缘168c限定,在杆162的接合位置构造成沿着侧面邻接或靠近壳体110的内表面并且围绕切口113的近端。更具体地,搁架168d构造成从侧壁168b向外延伸,并且因此从外表面168a向外延伸足够的距离,以便延伸超过切口113并且至少部分地与壳体110的内表面重叠。这样,搁架168d覆盖在杆162的近端操纵部163c的外表面168a和壳体110之间限定的任何间隙,从而阻止可视化壳体110的内部(相反,在任何间隙处只能看到搁架168d)。可以理解,搁架168d的特定宽度至少部分地基于上面提到的公差变化来确定,使得无论特定的公差变化如何,搁架168d充分地覆盖在杆162的近端操纵部163c的外表面168a和壳体110之间限定的任何间隙。除了考虑公差变化之外,搁架168d还用于覆盖由于杆162的近端操纵部163c相对于壳体110的横向和/或纵向移动而在杆162的近端操纵部163c的外表面168a和壳体110之间限定的任何间隙。
参考图7、10和11,近端止动件169a在近端操纵部163c的近端处设置在杆162的近端操纵部163c的搁架168d上,并从其朝向近端操纵部163c的外表面168a延伸。近端止动件169a包括止动表面169b和成角度的引导表面169c,成角度的引导表面设置在止动表面169b的任一侧上并且朝向彼此向内成角度,从而限定近端止动件169a的楔形构造。
近端止动件169a用作杆162的近端操纵部163c的正向止动件,以阻止杆162移动超过接合位置。更具体地,在杆162的接合位置中,近端止动件169a的止动表面169b邻接设置在近端邻近壳体113设置的壳体110的内表面的接收部分117的相应表面(参见图2、4、7和8),以在偏置构件166的偏压下阻止杆162的进一步行进。
近端止动件169a还用作居中特征,其中,当杆162朝向接合位置移动、近端操纵部163c相对于切口113处于偏心位置时,近端止动件169a的成角度的引导表面169c中的一个(取决于杆162的近端操纵部163c相对于切口113偏移的方向)接触壳体110的内表面的接收部分117(参见图2、4、7和8)的相应且互补的引导表面,使杆162的近端操纵部163c凸轮至与切口113对齐,使得在到达接合位置时,杆162的近端操纵部163c相对于切口113居中。
通常参考图1-4和7,描述了细长组件例如细长组件200与手柄组件100的插入和接合以及其使用。为了使细长组件200与手柄组件100接合,细长组件200的近端毂220插入通过旋钮组件170的外旋钮172并进入壳体110的远端鼻部116,其中闩锁组件160的接合齿180在近端毂220的倒角的近端边缘226上凸出,并且在近端毂220的环形通道224内结合,从而相对于壳体110可旋转地接合近端毂220。在通过旋转旋钮组件170插入近端毂220时,近端毂220的分度突出件222被接纳在外旋钮172的纵向延伸的凹槽178内,以相对于外旋钮172旋转地固定近端毂220。
如上所详述,在细长组件200与手柄组件100接合的情况下,可以操纵手柄组件100和/或可旋转外旋钮172,以将细长组件200的末端执行器260(图5)定位在待处理组织周围。一旦端部执行器260根据需要定位,触发器122朝向壳体110的固定手柄部分112枢转,以向远端推动连杆126,所述连杆126进而推动驱动杆130向远端通过壳体110,以通过细长组件200向远端驱动细长组件200的内部驱动组件(未示出),从而从端部执行器组件260(图5)击发并围绕组织形成手术夹。如果需要,可以重复上述内容以击发并围绕组织形成若干手术夹。
为了使细长组件200与手柄组件100脱离,例如用于清洁和/或消毒,或者为了用另一个细长组件替换细长组件200,闩锁组件160的杆162的近端操纵部163c向内凹入壳体110中,以使接合齿180从环形通道224脱离,从而使杆162与细长组件200的近端毂220脱离,并使近端毂220能够从壳体110和旋转旋钮组件170向远端撤回。
应该理解,前面的描述仅是对本公开的说明。在不脱离本公开的情况下,本领域技术人员可以设计出各种替代方案和修改。因此,本公开旨在涵盖所有此类替代、修改和变化。参考附图描述的实施方案仅用于证明本公开的某些实施例。与上文所述和/或所附权利要求中大致上不同的其它元件、步骤、方法和技术也旨在落入本公开的范围内。
