现在将参考附图详细描述所公开的外科缝合装置,其中若干视图的每个视图中类似的附图标号代表相同或对应的元件。然而,应当理解,本公开的各方面仅仅是本公开的示例,并且可以各种形式体现。未详细描述众所周知的功能或构造,以免不必要的细节模糊本公开。因此,本文所公开的特定的结构和功能细节不应理解为限制性的,而仅仅是权力要求书的基础,并作为具有代表性的基础用于教导本领域的技术人员以几乎任何合适的具体结构不同地采用本公开。此外,方向术语诸如前、后、上、下、顶部、底部、远侧、近侧和类似术语用于帮助理解本说明书,并且不旨在限制本公开。
在本说明书中,术语“近侧”一般用于指装置的更靠近临床医生的部分,而术语“远侧”一般用于指装置的更远离临床医生的部分。此外,术语“内窥镜式”一般用于指内窥镜式、腹腔镜式、关节镜式和/或通过小直径切口或插管进行的任何其他手术。此外,术语“临床医生”一般用于指包括医生、护士和支持人员在内的医务人员。
本公开涉及一种工具组件,该工具组件包括砧座和仓组件。仓组件包括第一尺寸的通道构件和第一尺寸的可替换钉仓。第一尺寸的通道构件限定放置凹陷部,并且第一尺寸的钉仓包括放置肋。放置肋被接纳在放置凹陷部内,以允许第一尺寸的钉仓被接纳在第一尺寸的通道构件内。不同尺寸的通道构件不包括放置凹陷部,以防止将第一尺寸的钉仓放置插入到第一尺寸的通道构件中。
图1示出了大体上如缝合装置10所示的所公开的外科缝合装置的示例性方面。缝合装置10包括柄部组件12、限定纵向轴线“X”的细长主体14和第一尺寸(例如60mm)的工具组件16。柄部组件12包括固定柄部18和触发器20,该触发器能够相对于固定柄部18运动以致动工具组件16。在本公开的各方面中,缝合装置10包括旋钮22和铰接杆24。旋钮22联接到柄部组件12并且支撑细长主体14,以促进细长主体14和工具组件16相对于柄部组件12围绕纵向轴线“X”的旋转。铰接杆24联接到工具组件16,以将工具组件16从与纵向轴线“X”对准的位置铰接到限定与纵向轴线“X”成锐角的位置。在缝合装置10的一些方面,柄部组件12包括用于回缩缝合装置10的驱动组件的回缩旋钮26。对于缝合装置10的柄部组件12的示例性方面的更详细的描述,参见例如美国专利第6,241,139号(“‘139专利”)。尽管柄部组件12被示出为手动操作的柄部组件,但是据设想,柄部组件12可以是电动柄部组件,诸如美国专利第9,055,943号中所述。
图2和图3示出了缝合装置10的工具组件16(图1)。工具组件16包括砧座28和仓组件30,该砧座和该仓组件能够相对于彼此在打开位置(图2)和夹紧位置之间运动。在本公开的各方面中,砧座28和仓组件30与枢转构件32联接在一起,使得仓组件32可以相对于砧座30在打开位置(图1)与夹紧位置(图8)之间枢转。尽管仓组件30被示出为朝向固定砧座28枢转,但是据设想,砧座30可以适于朝向固定仓组件30枢转。
仓组件30包括通道构件34和钉仓36。通道构件34包括限定开放腔42(图3)的底壁38和间隔侧壁40。钉仓36被可释放地接纳在开放腔42内,并且可在缝合装置10的每次击发之后替换,以促进缝合装置10(图1)的重复使用。通道构件34的尺寸被设计成接纳特定尺寸的钉仓36。例如,在工具组件16中,通道构件34的尺寸被设计成接纳具有一定尺寸的钉仓36,该尺寸对应于通道构件34的尺寸,例如30mm、45mm、60mm等。类似地,工具组件16的砧座28的尺寸被设定成与具有特定尺寸(例如60mm)的钉仓36一起使用。
图4至图6示出了第一尺寸(例如60mm)的工具组件16,该工具组件包括仓组件30、驱动组件50、致动滑动件52和闭锁构件54。驱动组件50包括柔性驱动梁60和工作端62。柔性驱动梁60具有支撑驱动组件50的工作端62的近侧部分64和远侧部分66。柔性驱动梁60的远侧部分66限定止动表面66a(图4)。在本公开的各方面中,驱动组件50的工作端包括呈I形梁形式的夹紧构件,该夹紧构件包括第一梁70、第二梁72和将第一梁70互连到第二梁72的竖直撑条74。在本公开的各方面中,竖直撑条74包括刀76的切割边缘。柔性驱动梁60的近侧部分64联接到支撑在外科缝合装置10的细长主体14(图1)内的驱动构件(未示出)。驱动构件(未示出)能够运动以使驱动组件50相对于砧座28和仓组件30在回缩位置与推进位置之间运动。
致动滑动件52被支撑在钉仓36内以用于在回缩位置(图6)与推进位置之间运动并且包括多个成角度的凸轮作用表面78。成角度的凸轮作用表面78定位成接合支撑在钉仓36内的推动器79(图6),以从钉仓36驱动钉。致动滑动件52定位在钉仓36内的驱动组件50的工作端68的远侧,并且当驱动组件50从其回缩位置朝向其推进位置运动以将致动滑动件52从其回缩位置运动到其推进位置时,由工作端68接合。
锁定构件54包括主体80,该主体具有居中定位的枢转构件82(仅示出一个)、一对向下延伸的远侧支腿84和近侧定位的止动构件86。锁定构件86能够围绕枢转构件82从第一解锁位置(图6)枢转到锁定位置,在该第一解锁位置,止动构件86定位在柔性驱动梁60的远侧部分66上的止动表面66a下方,在该锁定位置,止动表面66a与驱动组件50的柔性驱动梁60的远侧部分66上的止动表面66a对准。在锁定位置,锁定构件54阻挡驱动组件50朝向其推进位置的运动。锁定构件86通过偏置构件87(图10)朝向锁定位置偏置。当致动滑动件52处于其回缩位置时,锁定构件54的远侧支腿84与致动滑动件52接合,以将锁定构件54保持在解锁位置。美国专利第9,757,126号详细描述了锁定构件54和致动滑动件52的构造和操作。
第一尺寸的钉仓36包括限定中心刀槽102的仓体100和定位在中心刀槽102的每一侧上的多个钉凹坑104。在本公开的各方面中,钉凹坑104在中心刀槽102的每一侧上一排排地对准。尽管在中心刀槽102的每一侧上示出了三排钉凹坑104,但是据设想,钉仓36可以包括一排或多排钉凹坑104。仓体100还包括侧壁106(仅示出一个),该侧壁包括一个或多个突起部108。侧壁106中的每个侧壁包括悬伸部或肩部107,当钉仓36被插入到通道构件34的开放腔42中时,该悬伸部或肩部定位成搁置在通道34的侧壁40的顶部。在本公开的各方面中,突起部108中的一个或多个突起部可具有外肋表面110(图4)以提供抓握表面以促进钉仓36从通道构件34的移除。侧壁106还可以包括突起部106a,该突起部被接纳在仓盘109的开口109a内以将仓盘109保持在仓体100上。如本领域中已知的,仓盘109被固定到仓体,以将推动器79(图6)和钉(未示出)保持在仓体100内。仓体100的侧壁106中的至少一个侧壁包括放置肋112。在本公开的各方面中,放置肋112从至少一个侧壁106向外突出并且包括成角度的远侧表面114。在本公开的某些方面中,仓体100的侧壁106中的每个侧壁包括放置肋112。
如上所述,工具组件16的通道构件34包括限定开放腔42的底壁38和侧壁40。侧壁40包括切口120(图4),该切口接纳钉仓36的突起部108以将钉仓36固定在通道构件36的开放腔42内。当钉仓36被插入到通道构件34的开放腔42中时,钉仓36的弹性壁部分106a由通道构件34的侧壁40的内表面向内偏置,以有助于将钉仓36保持在通道构件42内。
第一尺寸(例如60mm)的工具组件16的通道构件34的侧壁40包括定位成接纳钉仓36的放置肋112的放置凹陷部128。在本公开的各方面中,放置凹陷部128部分地由成角度的远侧壁130(图4)限定,该成角度的远侧壁朝向砧座28沿远侧方向向上倾斜。如下所述,仅第一尺寸的工具组件16的通道构件34包括放置凹陷部128。当将第一尺寸的钉仓36插入到第一尺寸的通道构件34中时,放置肋112被接纳在放置凹陷部128内,以允许钉仓36被接纳在通道构件34的开放腔42内,使得钉仓的侧壁106上的肩部107搁置在通道构件34的侧壁40的顶部。当将钉仓36插入到通道构件34中时,限定放置凹陷部128的成角度的远侧壁130接合放置肋112的成角度的远侧表面114,以在通道构件34的开放腔42内向近侧推动钉仓,以将致动滑动件52(图4)运动成与锁定构件54(图6)接合,以使锁定构件54沿图6中由箭头“A”指示的方向枢转到其解锁位置。
图7至图10示出了当钉仓36插入到不同尺寸(例如45mm)的工具组件216的通道构件234中时的第一尺寸的钉仓36。第二尺寸的工具组件216的通道构件234与第一尺寸的工具组件16的通道构件34基本上相同,不同之处在于通道构件234不包括放置凹陷部。因此,当将第一尺寸的钉仓36插入到第二尺寸的通道构件234中时,钉仓36上的放置肋112接合工具组件216的通道构件234的侧壁240的上表面240a,以防止钉仓36适当地安置在通道构件234的腔242内。如图10所示,由于钉仓36不能适当地安置在工具组件216的通道构件234的腔242内,因此工具组件216的致动滑动件254不能接合锁定构件252,并且锁定构件252保持在解锁位置。因此,缝合装置10(图1)不能被击发。
上述第一尺寸的钉仓36和第一尺寸的通道构件34允许钉仓36仅被安置在适当尺寸的通道构件34内,并且防止第一尺寸的钉仓36插入到第二尺寸的通道构件234中。例如,如果第一尺寸的钉仓36是60mm的钉仓,并且第二尺寸的通道构件234的尺寸被设计成接纳45mm的钉仓,则当临床医生尝试将钉仓36插入到通道构件234的开放腔242中时,放置肋112将接合通道构件234的侧壁240,以防止钉仓36适当地安置在腔242内。
尽管本文将第一尺寸描述为60mm的钉仓或工具组件,并且第二尺寸被描述为45mm的钉仓或工具组件,但是据设想,本公开的各方面可以并入各种不同尺寸的钉仓和工具组件中。
本领域的技术人员将会理解,本文具体描述并在附图中示出的装置和方法是本公开的非限制性的示例性方面。据设想,在不脱离本公开的范围的情况下,结合本公开的一个示例性方面示出或描述的元件和特征可与另一个方面的元件和特征组合。同样,本领域的技术人员将基于本公开的上述方面理解本公开的另外的特征和优点。因此,本公开不受已具体示出和描述的内容的限制,除非由所附权利要求书指出。
