使用手术器械,对于外科医生来说使砧座构件和钉仓构件接近是常见的。其次,外科医生可发射器械来将紧固件安置在组织中。此外,外科医生可使用相同的器械或另外的器械来切割邻近或在多行紧固件之间的组织。
另外,单次使用装载单元(“SULU”)或可替换的装载单元(“DLU”)可被附接至手术吻合器械的细长部或内窥镜部。例如,这种装载单元允许手术吻合器械具有更大的通用性。装载单元可被配置为单次使用,和/或可被配置为不止一次使用。
进一步地,末端执行器和/或装载单元的尺寸主要被包含在其中的各种部件所限定。也就是说,尽管对具有比那些典型可用的直径更小的末端执行器和/或装载单元可能存在需求,但是末端执行器和/或装载单元的直径典型地被例如包含在其中的吻合钉推进器、工字梁、致动滑块以及紧固件的尺寸、几何形状和/或方位所限定。

具体实施方式
参考附图,详细地描述本公开的手术器械、用于随其使用的装载单元、以及用于随其使用的钉仓组件的实施例,其中相同的附图标记指代多幅视图的每一幅视图中的相应的元件。正如本领域中通用的,术语“近侧”指的是更靠近用户或操作者(如外科医生或内科医生)的部件或组件,而术语“远侧”指的是更远离用户的部件或组件。
在图1和图2中,本公开的手术器械表示为附图标记100。通常地,手术器械100包括手柄组件110、从手柄组件110向远侧延伸的细长主体部120、以及邻近细长主体部120的远侧端布置的装载单元200。图1图示出包括第一手柄组件110(如电动手柄组件)的手术器械100,以及图2图示出包括第二手柄组件110的手术器械100。还预想到可以使用其它类型的手柄,如电机驱动的、液压的、齿合的(ratcheting)等。正如在此使用的,“手柄组件”包含手柄组件的全部类型。装载单元200被附接于手术吻合器械100的内窥镜部120,例如允许手术器械100具有更大的通用性。正如在此使用的,“装载单元”既包含单次使用的装载单元(“SULU”)又包含可替换的装载单元(“DLU”)。另外地或选择地,手术器械100可具有在器械的可再用钳夹中的可拆卸的且可替换的钉仓。
用于与手术吻合器械一起使用的装载单元的实例被公开在授予Bolanos等人的共同拥有的美国专利第5,752,644号中,该专利的全部内容通过在此引用由此合并。内窥镜手术吻合器械的进一步细节被详细描述在授予米利曼(Milliman)等人的共同拥有的美国专利第6,953,139号中,该专利的全部内容通过在此引用由此合并。
在根据本公开的手术器械100中,发射杆通过手柄组件110的致动向远侧移动,以部署紧固件600。参考图1中图示的实施例,开关112的至少部分致动使发射杆纵向平移。参考图2中图示的实施例,活动手柄132相对于固定手柄134的至少部分致动使发射杆纵向平移。发射杆的平移导致刀杆140的平移和滑块杆(sled bar)150的平移(例如,见图17和图18,具体参考图18,刀杆140包括连接在一起的近侧部140a和远侧部140b)。进一步地,刀杆140的平移导致夹紧构件500的平移,以使至少一个钳夹构件相对于另一个钳夹构件接近,并且滑块杆150的平移导致致动滑块520的平移,以使紧固件600从钉仓组件400的凹处401弹出。
参考图3至图5,示出本公开的装载单元200。装载单元200包括限定纵向轴线“A-A”的近侧主体部210,以及包括一对钳夹构件(即砧座组件300和钉仓组件400)的工具组件或末端执行器220。近侧主体部210被配置为可拆卸地附接至手术器械100的内窥镜部120。更具体地,装载单元200的插入接头202成直线地插入手术吻合器械100的内窥镜部120的远侧端。插入接头202的凸起物204通过邻近内窥镜部120的远侧端形成的狭槽成直线地移动。随后,装载单元200关于纵向轴线“A-A”旋转,以使得凸起物204通过在内窥镜部120内的狭槽横向移动。另外,在装载单元200和内窥镜部120的接合期间,手柄部110的发射杆接合装载单元200的刀杆140。
参考图6,夹紧构件500包括工形截面,该工形截面包括被配置为接合砧座组件300的顶部502、被配置为接合钉仓组件400的底部504、以及连接顶部502和底部504的竖直部503,并且该竖直部503可包括在其远侧表面的切割边缘506。更具体地,在夹紧构件500的底部504和钉仓组件400之间的接合有助于使砧座组件300和钉仓组件400相对于彼此维持在相对位置。
进一步论及致动滑块520,致动滑块520的远侧平移顺序地接合多个推进器540,并且导致推进器540向钉仓组件400的相应组织接触表面410移动且向砧座组件300弹出紧固件600。在紧固件600的弹出之后,夹紧构件500的切割边缘506可被包含在它的远侧面以切断已吻合的组织。
参考图6至图18,图示出装载单元200的进一步细节。通常,在此公开的装载单元200的特征允许装载单元200具有与具有大约12mm直径的器械相比的相对小的直径(如7mm至8mm)。装载单元200的直径在砧座组件300的径向最外壁和钉仓组件400的径向最外壁之间测量(见图6)。这种薄断面允许装载单元200被插入具有相似直径的套管针。如可被意识到的,这些薄断面的装载单元200在儿科手术和/或其它的如薄组织区位中是有用的。另外,在图示的实施例中,装载单元200的近侧主体部210的近侧部212被定尺寸且配置为接合具有更大直径的细长部120(如大约12mm)的手术器械的细长部,这样允许更大的通用性。
具体参考图6,从远侧端示出装载单元200的径向截面。如所示的,推进器540、紧固件600、砧座组件300的组织接触表面310、以及钉仓组件的组织接触表面410相对于平面C-C(图8)以非直角布置。平面C-C延伸穿过纵向轴线A-A且穿过竖轴线B-B,该竖轴线B-B由夹紧构件500的竖直部503限定。进一步地,竖轴线B-B是在平面C-C内。例如这些非直角、以及夹紧构件500的相对薄断面(同更大的(如12mm)器械的夹紧构件相比),有助于使装载单元200能够具有小直径。预想到夹紧构件500的总高度在大约1mm和大约2.5mm之间,或大约2mm。
进一步参考图6和另外参考图11至图13和图17至图18,示出装载单元200的进一步细节。具体参考图17和图18,装载单元200的截面被示出且包括刀杆140、滑块杆150、砧座组件300、钉仓组件400、夹紧构件500以及致动滑块520。具体参考图6和图12,钉仓组件400包括钉仓408(包括两个半部)和钉仓通道409。钉仓408被布置在钉仓通道409内。
在使用中,如上文所述,发射杆的远侧平移迫使刀杆140向远侧平移。进一步地,刀杆140的远侧平移导致刀杆140的突起143(见图17)接触滑块杆150的近侧面151,这导致滑块杆150的远侧平移。随着滑块杆150向远侧移动,滑块杆150的远侧面152接触钉仓组件400的凸轮表面402,这导致钉仓组件400向砧座组件300移动。另外,随着刀杆140向远侧移动,夹紧构件500的顶部502在砧座组件300内的狭槽304内向远侧被推进,而且夹紧构件500的底部504在钉仓组件400的钉仓通道409内的狭槽414内向远侧被推进,以有助于使钳夹构件相对于彼此稳固且有助于维持钳夹构件之间的固定间隙。如此,发射杆的远侧移动的预定量导致钳夹构件的接近和稳固。
发射杆的继续推进以及因此刀杆140的继续推进,导致滑块杆150向致动滑块520的近侧面522的继续推进,进而导致致动滑块520的远侧移动。随着致动滑块520向远侧推进,它的倾斜凸轮表面524(见图6和图12)接触推进器540的凸轮表面,这样导致推进器540接合紧固件600,并且随后导致紧固件600向砧座组件300的相应凹处320弹出(例如,穿过保持在钳夹构件之间的组织)。如所示的(如图6中),致动滑块520包括大体V形断面。如所示的(如图12中),每个推进器540包括通过连接件542相互连接的两个纵向隔开的紧固件接触部或推进器板544。另外,发射杆的继续推进也导致刀杆140和夹紧构件500的继续推进,以使得夹紧构件500的顶部502继续在砧座组件300的狭槽304内移动,而且夹紧构件500的底部504继续在钉仓通道409的狭槽414内移动。另外,夹紧构件500的切割边缘506,如果被包含在夹紧构件500上,那么切断被布置在钳夹构件之间的组织(而且在组织已经被紧固之后,如上文所述)。滑块凸轮期望倾向于被布置成在大约相同时间内发射全部四行吻合钉,以正好在刀具切割组织之前使组织密封在刀具狭槽的两边。
如所示的,并且如上文所述的,装载单元200的各种结构件被定尺寸且被定向于允许装载单元和钳夹构件的小直径(如7mm)。具体地,致动滑块520的凸轮表面524、推进器540、凹处401以及紧固件600相对于竖轴线B-B(延伸穿过纵向轴线A-A)以第一非直角(如在大约15°和大约40°之间,或在大约20°和大约35°之间)布置。进一步地,砧座组件300和钉仓组件400相应的组织接触表面310、410以相应的第二非直角布置,以便于组织接触表面310沿相应表面的各自总长的至少大部分、基本上平行于组织接触表面410,以及便于第一非直角和第二非直角基本上正交于彼此(即紧固件600以一角度布置,例如该角度基本上正交于砧座300的组织接触表面310的角度)。另外,夹紧构件500布置在由致动滑块520的凸轮表面524之间和在推进器540之间的角度形成的空间内(见图6)。
现在参考图5、图7、图8、图11、图13和图16,示出手术器械100的关节式运动机构。关节式运动机构允许装载单元200的末端执行器220能够关于近侧主体部210枢转(见图5)。关节式运动机构包括邻近细长主体部120布置的关节式运动柄700(见图1和图2)、与关节式运动柄700机械合作地布置的关节式运动连杆、与关节式运动连杆能接合并且延伸穿过装载单元200的近侧主体部210且进入与末端执行器220的近侧部222的关节式运动销223接合的关节式运动杆710、以及被布置在近侧主体部210和装载单元200的末端执行器220之间的枢转组件720。具体参考图13,枢转组件720包括连杆722,该连杆722可枢转地联接近侧主体部210的稳定件724和末端执行器220的近侧部222的连杆销224(图16)。另外,一对夹子730在近侧主体部210和末端执行器220之间延伸。如图8中所示,刀杆140在夹子730之间延伸。在某些实施例中,夹子起安全板(blowout plate)的作用,该板具有被固定在设备中的末端。
在使用中,关节式运动柄700以第一方向(例如,逆时针)的旋转导致关节式运动连杆和关节式运动杆710的远侧移动,从而导致末端执行器220相对于近侧主体部210以第一方向(例如,图5中箭头“C”)枢转;关节式运动柄700以第二方向(例如顺时针)的旋转导致关节式运动连杆和关节式运动杆710的近侧移动,从而导致末端执行器200相对于近侧主体部210以第二方向(例如与箭头“C”相反)枢转。
本公开还包括使用手术器械100、装载单元200和/或钉仓组件400的方法,这论述于此。
尽管上述说明包含许多细节,但是这些细节不应该解释为对本公开的范围的限制,而是仅仅作为它的各种实施例的图解。因此,上述说明不应该被解释为限制,而是仅仅作为各种实施例的例证。本领域的技术人员将预想到在附加于此的权利要求书的范围和精神内的其它修改。
