Description

套管针末端保护器
技术领域
本公开总体上涉及手术吻合装置。更具体地，本公开涉及用于手术吻合装置的致动单元的可重复使用接合器和延伸组件的可选择性移除的保护装置。
背景技术
用于在手术操作中使用的动力与手动的手术吻合装置典型地包括手柄组件与末端执行器。为了允许重复使用这些手术吻合装置的手柄组件并且便于手柄组件可以与多种末端执行器一起使用，已经开发出了接合器组件与延伸组件来用于选择性附接至手柄组件及多种末端执行器。使用后，接合器和/或延伸组件可以被消毒用于被重复使用。
很多接合器组件与延伸组件包括从远侧端突出的套管针。套管针可以用于刺穿组织并作为引导件来更容易地将接合器组件或延伸组件对准末端执行器。为了便于刺穿组织，套管针典型地包括锋利的远侧末端。
在手术操作期间使用具有套管针的接合器或延伸组件的情况下，作为对消毒过程的准备，接合器和/或延伸组件的套管针可能会暴露，这样给手术室的人员或其他控制组件的人带来刺伤或划伤的风险。因此，存在针对用于动力和/或手动的手术吻合装置的致动单元的可重复使用接合器与延伸组件的可移除保护装置的需求。
发明内容
本公开旨在一种包括手术器械与保护装置的手术系统。所述手术器械包括可释放地联接到其上的延伸组件，并且包括布置在其远侧端中的套管针构件。套管针构件包括限定在其外表面中的接合部件。保护装置可释放地联接至套管针构件的接合部件，由此提供邻近套管针构件的末端的屏障。

保护装置的第二端可以包括矩形底座，所述矩形底座具有比手术器械的壳体的外径大的外边缘。保护装置的第二端可以包括凸缘，所述凸缘具有比围绕套管针构件的壳体的外径大的外径。
根据另一方案，本公开旨在一种用于对手术器械消毒的方法。所述方法包括：提供手术器械，所述手术器械具有可释放地联接至其上的延伸组件。所述延伸组件包括布置在其远侧端内的套管针构件，其中，套管针构件的至少一部分从延伸组件的远侧端突出。套管针构件包括限定在其外表面内的接合部件。
所述方法进一步包括提供配置为可释放地联接至套管针构件的接合部件的保护装置；推进保护装置经过套管针构件并部分地在延伸组件的远侧端内限定的腔内，直到保护装置可释放地接合套管针构件的接合部件，由此提供邻近套管针构件的尖的远侧末端的屏障；将带有可释放地附接至其上的保护装置的延伸组件从手术器械移除；以及将带有可释放地附接至其上的保护装置的延伸组件放入消毒室。
所述方法还可以包括如下的保护装置，其具有布置在其远侧端上的多个腿部。多个腿部可以从保护装置的远侧端轴向延伸，并终止于限定在其内表面上的倒钩部处。多个腿部中的每个倒钩部可以接合套管针构件的接合部件，由此将保护装置可释放地联接至套管针构件。
所述方法还可以包括保护装置的、具有限定钝末端的圆锥形构造的近侧端，由此阻止临床医生接触套管针构件的尖的远侧末端。
所述保护装置可以具有限定在其外表面中的环形沟槽，所述环形沟槽配置为允许抓握细长主体。

具体实施例
现将参照附图对本公开的实施例进行详细的描述，其中在几幅视图的每个视图中相同的附图标记表示相同或相应的元件。正如此处所使用的，术语“临床医生”指医生、护士或护理提供者且可以包括支持人员。在整个说明中，术语“近侧”将指代装置或其部件的较靠近临床医生的部分，而术语“远侧”将指代装置或其部件的较远离临床医生的部分。另外，在以下的附图与描述中，仅仅是为了便于描述而使用诸如前、后、上、下、顶、底及类似的方向术语的术语，而并非意在限制本公开。在以下的描述中，熟知的功能或结构未进行详细描述以避免不必要的细节使本公开模糊不清。
参照图1，示出了适于与套管针末端保护器(保护装置)200(图5)一同使用的动力手术吻合装置(手术器械)，并总体地标示为附图标记100。动力手术吻合装置100包括接合器组件110、延伸组件120以及手柄组件130。如图1所示，手柄组件130配置为与接合器组件110选择性地连接，并且接下来，接合器组件110配置为与延伸组件120选择性地连接。延伸组件120配置为与圆形装载单元140(图2)及砧座组件144(图2)选择性地连接，用于将环形阵列的吻合钉(未示出)施加至组织(未示出)。
手柄组件130包括手柄壳体132以及下壳体部134、从下壳体部134延伸和/或被支撑在下壳体部134上的中间壳体部136以及从中间壳体部136延伸和/或被支撑在中间壳体部136上的上壳体部138。上壳体部138的远侧半部限定前端或连接部138a，所述前端或连接部138a配置为接收接合器组件110的相应的驱动器联接组件(未示出)。对于示例性手术装置的结构及功能的详细描述，请参照共有美国专利申请公开第2012/0253329号，其全部内容通过引用合并于此。
接合器组件110包括：近侧端112，其配置为可操作地连接至手柄组件130的连接部138a；以及远侧端114，其配置为可操作地连接至延伸组件120。对于示例性接合器组件的结构及功能的详细描述，请参照共有美国专利申请公开第2012/0253329号，其全部内容通过引用合并于此。
延伸组件120配置为将接合器组件110可操作地连接于圆形装载单元140(图2)及砧座组件144(图2)，用于将环形阵列的吻合钉(未示出)施加于组织(未示出)。延伸组件120包括近侧端122，所述近侧端122配置成可操作地连接于接合组件110的远侧端114。延伸组件120的远侧端124配置成可操作地连接于装载单元140及砧座组件144。可以想到的是，任何适合的装载单元、砧座组件以及接合器组件都可以与延伸组件120一同被利用。示例性装载单元与砧座组件在共有美国专利第8,590,763号以及美国专利申请序列第14/056,301号与第14/149,355号中进行了描述，其全部内容通过引用合并于此。
延伸组件120包括套管针组件150(图3、图4以及图4A)，所述套管针组件150布置在延伸组件120的外套筒126中并从远侧端124突出，如图3中最佳地示出的。套管针组件包括具有远侧端155a的壳体155。套管针组件150的远侧端包括套管针构件152，所述套管针构件152限定具有尖的末端152a的大体圆柱形构造。套管针构件152的近侧端包括环形沟槽154，所述环形沟槽154限定在套管针构件152的外表面内并且形成适于选择性地接合砧座组件144的近侧朝向唇缘154a。参照图5，根据本公开设置的套管针末端保护器(保护装置)的示例性实施例被示出，并总体上标识为附图标记200。套管针末端保护器200包括细长主体210，所述细长主体210包括近侧端212以及远侧端214。尽管细长主体210通常被示出为包括圆形截面，但可想到的是，细长主体210可以包括任何适合的形状，例如正方形、长方形、八边形等。近侧端212通常被示出为限定大体圆锥形，限定出钝末端212a。凹槽216被限定在细长主体210的外表面中，且适于使临床医生能够容易地抓握细长主体210。尽管通常被示出为具有圆形形状，但可以想到的是，凹槽216可以包括使得能够易于抓握的任何形状。多个腿部218从远侧端214远侧地延伸，并终止于倒钩部220。每个腿部218的倒钩部220径向地向内延伸，使得倒钩部220可以可释放地接合套管针构件152的环形沟槽154。以这种方式，在没有外力时，倒钩部220被禁止向远侧越过环形沟槽154的近侧朝向唇缘154a(例如，腿部218向上偏斜并越过唇缘154a)。如图8与图8A中最佳地示出的，套管针末端保护器200被推进经过套管针构件154，直到尖的远侧末端152a定位于套管针末端保护器200的主体210内部为止，由此阻止临床医生接触锋利的远侧末端152a。尽管套管针末端保护器200通常被示出为具有四条腿部，但可以想到的是，可以采用任何合适数量的腿部以使得套管针末端保护器200可释放地接合套管针构件152的环形沟槽152，例如2、3、5、6等。如能够意识到的，套管针末端保护器200可以由任何适于在消毒过程中使用的材料制成，例如金属材料、聚合物材料或复合材料。
在操作中，参照图1至图7，在对患者执行手术操作且已经发射了装载单元140后，延伸组件120可以被从接合器组件110移除。也可以想到的是，接合器组件110与延伸组件120两者可以一起被从手柄组件130移除。在将延伸组件120从接合器组件110移除后，砧座组件144可以被从套管针组件152移除，在那之后，装载单元140可以被从延伸组件120的远侧端移除，由此暴露出套管针构件152的锋利的远侧末端152a。在此时，套管针末端保护器200可以被推进经过套管针构件152的尖的远侧末端152a，并进入限定在延伸组件120的外套筒126的远侧端124中的空腔126a。套管针末端保护器200可以被继续推进经过套管针构件152，直到套管针末端保护器200的倒钩部220完全接合套管针构件152的环形沟槽154，从而使套管针末端保护器200的一部分布置在空腔126a中并且套管针末端152a定位于主体210中。套管针末端保护器200由此提供了邻近尖的远侧末端152a的屏障，并阻止临床医生或其他人员与尖的远侧末端152a接触。以这种方式，保护临床医生或其他人员免于可由接触尖的远侧末端152a造成的刺伤或擦伤。具有套管针末端保护器200固定其上的延伸组件120可以在之后被放进合适的消毒室中并可以开始消毒过程。可以想到的是，接合器组件110、延伸组件120以及套管针末端保护器200可以作为装配单元被放置在合适的消毒室中。在消毒过程完成后，仍然附接有套管针末端保护器200的延伸组件120可以被从合适的消毒室中移出并放置在一旁，直到新的装载单元140已经准备好被安装至延伸组件120上。只有在这个时候，套管针末端保护器200才被从套管针构件152移除，因此保护临床医生在上文描述的过程中免于任何擦伤或刺伤。
现在参照图6，根据本公开的另一示例性实施例设置的套管针末端保护器(保护装置)的另一实施例被示出并总体上被标示为附图标记300。套管针末端保护器300包括主体310、凹槽316和从主体310的远侧端314延伸的腿部318上的倒钩部320。因此，除了近侧端312限定大致平面结构以外，套管针末端保护器300与套管针末端保护器200基本上相似。在操作中，套管针末端保护器300以与套管针末端保护器200的方式相似的方式被利用，为此，为了简洁起见，此处将不再详细描述套管针末端保护器300的操作。
现在转到图7，根据本公开的套管针末端保护器(保护装置)的又一实施例被示出并总体上被标示为附图标记400。套管针末端保护器400包括主体410、凹槽416和从主体410的远侧端414延伸的腿部418上的倒钩部420。因此，除了近侧端412包括限定圆形凸缘412a的展开远侧端(flared distal end)且该圆形具有比细长主体410的外径大的外径以外，套管针末端保护器400与套管针末端保护器200基本上相似。凸缘412a的更大的外径提供了大的表面积，用于临床医生来抓握。尽管近侧端412的近侧表面412b通常被示出为具有形成于其中的凹陷部，但可以想到的是，近侧表面412b可以包括任何适合的形状，例如凸面的、平面的等。在操作中，套管针末端保护器400以与套管针末端保护器200的方式类似的方式被利用，为此，为了简洁起见，此处将不再详细描述套管针末端保护器400的操作。
尽管此处已经针对动力吻合装置的套管针末端保护器进行了描述，但自然应该理解，此套管针末端保护器也同样适合于与手动吻合装置一同使用。例如，参照图9，适合于与根据本公开的套管针末端保护器一同使用的手动手术吻合装置被示出并总体上被标示为附图标记500。手动手术吻合装置500通常包括手柄组件510、延伸组件520，其中所述延伸组件520从手柄组件510远侧地延伸并终止于远侧端524。套管针组件550布置在延伸组件520中且从延伸组件520远侧地延伸。套管针组件550相似于上文描述的延伸组件120的套管针组件150，为此，为了简洁起见，此处将不对套管针组件150的细节进行详细地论述。对于示例性手动手术吻合装置的结构及功能的详细描述，请参照美国专利申请公开第2014/0263548号，其全部内容通过引用合并于此。在操作中，套管针末端保护器可以采用与上面关于动力手术装置100描述的方法相似的方式选择性地固定至套管针组件150。
现在参照图10及图11，根据本公开的套管针末端保护器(保护装置)的另一示例性实施例被示出并总体上被标示为附图标记600。套管针末端保护器600包括主体610、凹槽616以及从主体610的远侧端614延伸的腿部618上的倒钩部620。因此，除了近侧端612包括长方形底座617以外，套管针末端保护器600与前文公开的套管针末端保护器200、300、400基本上相似。长方形底座617具有比主体610的外径与装载单元140的外径大的外边缘。底座617的矩形构造提供了比套管针末端保护器300的近侧端312(图6)的表面积与套管针末端保护器400的凸缘412a(图7)的表面积更大的表面积。底座617的该增加的表面积允许底座617被放置在水平表面(例如，桌子、工作台面等)上，以便临床医生可以向套管针末端保护器600推动接合器组件110，使得套管针组件150的突出的尖的末端152a被接收在主体610中，因此阻止临床医生接触锋利的远侧末端152a。底座617的增加的表面积提供了高度稳定性并降低如下的可能性：当临床医生将尖的末端152a插入主体610时，底座617将会移动或晃动。另外，套管针末端保护器600具有在凹槽616的近侧定位的凸缘615。凸缘615具有比远侧端614与腿部618大的外径。凸缘615的外径也大于套管针组件150的壳体155的外径。由于凸缘615的外径大于壳体155的外径，那么在套管针末端保护器600联接至套管针组件150时，套管针末端保护器600阻止临床医生完全撤回套管针组件150。由于套管针构件152的近侧移动将导致套管针末端保护器600的相应的近侧移动，直到凸缘615抵接壳体155的远侧端155a，那么套管针构件152的近侧移动量会受到限制，因此阻止套管针构件152的进一步的近侧移动。
本领域技术人员可以理解的是，此处具体描述并在附图中示出的装置与方法不限于示例性实施例。可以想到的是，关联一个示例性实施例被示出或描述的元件和特征可以与关联另一实施例的元件和特征相组合而不脱离本公开的范围。同样，本领域的技术人员基于上面描述的实施例将能够想到本公开的更多的特征与优势。因此，除了如附属权利要求所指示的以外，本公开不被所具体示出与描述的限定。
