技术领域
本公开涉及圆形钉合装置并且更具体地涉及包括不可变形钉并且不需要精确形成的钉变形凹座的圆形钉合装置。
背景技术
圆形钉合装置常用于执行接合两个管状组织切片的吻合程序。通常,圆形钉合装置包括具有限定支撑环状阵列的钉的多个钉接收凹座的钉仓的壳体组合件,和包括限定环状阵列的钉变形凹座的钉变形表面的砧座组合件。在钉形成期间,钉凹座必须与钉变形凹座对准以恰当地形成钉并且在组织切片中创建无渗漏钉线。术后钉线渗漏可导致感染和甚至死亡。
在已知的圆形钉合装置中,砧座组合件包括支撑花键的砧座中心杆。壳体组合件包括壳体外壳,所述壳体外壳还包括将花键接收在砧座中心杆上的花键以将钉仓的钉接收凹座与在砧座组合件上的钉变形凹座恰当地对准。然而,在砧座中心杆和/或壳体外壳上的花键可能会被损坏,使得钉仓的钉接收凹座和在砧座组合件上的钉变形凹座不恰当地对准。对花键的损坏可由“猛撞”引起,这当在砧座中心杆上的花键接合在壳体外壳头部上的花键时发生,使得一些花键断裂。
在钉合领域中持续需要不要求有助于适当钉形成的在钉仓的钉接收凹座和在砧座组合件上的钉变形凹座之间的对准的圆形钉合装置。
发明内容
本公开的一个方面涉及包括手柄组合件、主体部分和工具组合件的圆形钉合装置。主体部分具有近侧部分和远侧部分。主体部分的近侧部分连接到手柄组合件。工具组合件支撑在主体部分的远侧部分上并且包括砧座组合件和壳体组合件。砧座组合件包括中心杆和砧座头部组合件。中心杆具有近侧部分和远侧部分。砧座头部组合件固定到中心杆的远侧部分并且包括限定外环状凹槽的外壳和放置在外环状凹槽内的锁定材料。壳体组合件包括壳体外壳和钉仓。钉仓支撑与外环状凹槽轴向对准的多个钉。多个钉中的每一个包括后跨部和从后跨部的每一个端部延伸的支腿。支腿中的每一个包括被配置成在通过钉的支腿穿透锁定材料时接合砧座头部组合件的锁定材料以阻挡支腿从锁定材料内缩回的锁定结构。
本公开的另一个方面涉及包括中心杆和砧座头部组合件的砧座组合件。中心杆包括近侧部分和远侧部分。砧座头部组合件包括中心立柱、外壳、切口环和锁定材料。中心立柱固定到中心杆的远侧部分。外壳限定放置在中心立柱周围的外环状凹槽和内环状凹槽。锁定材料放置在外环状凹槽内,并且切口环放置在内环状凹槽内。

在某些实施例中,外壳包括限定外环状凹槽的面向近侧的表面,并且加强材料放置在锁定材料上方的面向近侧的表面上。
在实施例中,锁定结构包括沿多个钉的支腿的至少一部分放置的齿。
在一些实施例中,支腿中的每一个限定纵向轴线,并且在支腿中的每一个上的齿包括限定与支腿的纵向轴线成锐角的远侧表面。齿的远侧表面在近侧方向上从纵向轴线向外延伸。
在某些实施例中,在支腿中的每一个上的齿包括被配置成当多个钉的支腿穿透网材料时接合网材料以防止支腿从网材料缩回的近侧表面。
在实施例中,齿中的每一个的近侧表面垂直于支腿的纵向轴线。
在一些实施例中,砧座头部组合件的外壳限定放置在环状凹槽内的内环状凹槽,并且钉合装置进一步包括支撑在内环状凹槽内的切口环。
在某些实施例中,砧座头部组合件可枢转地固定到中心杆。
在实施例中,钉合装置进一步包括手柄组合件和具有远侧部分的从手柄组合件延伸的主体部分,其中工具组合件支撑在主体部分的远侧部分上。
本公开的另一个方面涉及包括砧座组合件和钉仓的工具组合件。砧座组合件相对于钉仓在间隔和夹持位置之间可移动。砧座组合件包括限定凹槽的外壳和放置在凹槽内的锁定材料。钉仓包括限定多个钉接收狭槽的主体。钉接收狭槽中的每一个支撑多个钉的一个钉。当砧座组合件和钉仓处于夹持位置时,钉接收狭槽与凹槽对准,使得当启动工具组合件时多个钉弹出并且穿透到网材料中。多个钉中的每一个包括后跨部和从后跨部的每一个端部延伸的支腿。支腿中的每一个包括被配置成在通过钉的支腿穿透网材料时接合砧座组合件的网材料以阻挡支腿从锁定材料缩回的锁定结构。

具体实施方式
现将参考附图详细描述本发明公开的圆形钉合装置,在附图中,类似参考数字表示若干视图的每个视图中的相同或对应元件。然而,应理解,所公开的实施例仅仅为本公开的例示性,并且可用各种形式来实施。未详细地描述众所周知的功能或构造以免用不必要的细节混淆本公开。因此,本文所公开的特定的结构和功能细节不应被解释为限制性的,而是仅仅应被解释为权利要求书的基础,和用于教导所属领域的技术人员以实际上任何适当的详细结构以不同方式使用本公开的代表性基础。
在此描述中,术语“近侧”一般是指装置的较接近于临床医生的部分,而使用术语“远侧”一般是指装置的距临床医生较远的部分。此外,使用术语“内窥镜”一般是指内窥镜、腹腔镜、关节镜和/或通过小直径切口或套管进行的任何其它程序。另外,使用术语“临床医生”一般是指医务人员,包括医生、护士和辅助人员。
本发明所公开的圆形钉合装置包括砧座组合件和壳体组合件。砧座组合件包括限定支撑锁定材料的外环状凹槽的砧座头部。壳体组合件包括支撑与砧座头部的外环状凹槽对准的环状阵列的钉的钉仓。环状阵列的钉的钉中的每一个包括后跨部和从后跨部的每一个端部延伸的支腿。支腿具有被配置成便于钉的支腿穿过组织并且与锁定材料锁定接合的锁定结构。在实施例中,锁定结构包括多个齿,但是可使用其它锁定结构。当启动圆形钉合装置时,钉从钉仓弹出并且穿过组织并且进入锁定材料。齿接合锁定材料以防止钉的支腿从组织缩回。提供与环状阵列的钉对准的锁定材料的环圈避免需要在启动来自钉仓的钉之前钉仓与砧座头部恰当地对准。
图1和2说明大体上示出为钉合装置10的本发明所公开的手术钉合装置的一个例示性实施例。钉合装置10包括手柄组合件12、主体部分14和工具组合件16。手柄组合件12包括接近旋钮18、启动触发器20和触发锁定装置22。工具组合件16包括砧座组合件24和壳体组合件26。主体部分14具有支撑在手柄组合件12上的近侧端部和支撑工具组合件16的远侧端部。主体部分14包括管状外壳28和砧座保持器30(图2)。管状外壳28支撑壳体组合件26,并且砧座保持器30(图2)延伸通过管状外壳28和工具组合件16的壳体组合件26并且支撑砧座组合件24。砧座保持器30在主体部分14内可移动以相对于壳体组合件26在间隔(图1)和夹持(图11)位置之间移动砧座组合件24。
美国专利第9,492,168号(“'168专利”)和美国专利公开第2015/0351769号公开手动操作的包括上文识别的组件的手术钉合装置。这些文献均以全文引用的方式并入本文中。虽然图1说明手动操作的钉合装置,但是设想钉合装置10也可电力驱动或被配置成用于附接到机器人控制的系统。美国公开第2015/0014392号和第2015/0048140号描述电力驱动的手术钉合装置并且全文以引用的方式并入本文中。
参考图2和3,壳体组合件26包括壳体外壳34、推动器36、环状刀37(图12)、钉仓38和多个钉40。钉仓38支撑在壳体外壳34的远侧部分中并且限定环状阵列的钉接收凹座38a。钉接收凹座38a中的每一个支撑钉40(图3)。对于壳体组合件的更详细描述,参见'168专利。
此外参考图4-7,砧座组合件24包括砧座中心杆42和砧座头部组合件44。砧座中心杆42具有被配置成可释放地耦接到砧座保持器30(图2)的近侧部分,和远侧部分。在一些实施例中,砧座头部组合件44通过枢转构件45可枢转地支撑在砧座中心杆42的远侧部分上。替代地,砧座头部组合件44可固定地安装到砧座中心杆42。
砧座头部组合件24包括外壳50、固定到外壳50或与外壳50一体地形成的立柱52、切口环54、加强材料56和锁定材料58。外壳50限定内环状凹槽60、外环状凹槽62和面向近侧的支撑表面64。内环状凹槽60放置在立柱52周围并且接收切口环54,使得切口环54被放置成当启动钉合装置10时,接合壳体组合件26的环形刀37(图12)。如所属领域中已知,切口环54可由多种不同材料形成并且具有一层或多层材料。外环状凹槽62放置在内环状凹槽60的径向外侧在当启动钉合装置10时接收来自钉仓38的钉40的位置处。锁定材料58放置在外环状凹槽62内以接收钉40,如下文进一步详细论述。加强材料56支撑在外壳50的面向近侧的表面64上并且在外环状凹槽62和锁定材料58上方延伸。在实施例中,加强材料56使用粘合剂固定到外壳50的面向近侧的表面,但是设想其它附接手段。
锁定材料58由为可生物吸收、不可吸收、天然或合成材料的生物相容性基质形成,其被配置成与钉40啮合或互锁以防止钉从锁定材料缩回。在实施例中,锁定材料58由生物相容性网形成。替代地,具有必需特性的其它材料也可用作锁定材料。
在实施例中,加强材料56可由为可生物吸收、不可吸收、天然、合成、织造或非织造材料的生物相容性基质材料构成。举例来说,加强材料可由以下形成:聚(乳酸)、聚(乙醇酸)、聚(三亚甲基碳酸酯)、聚(二氧环己酮)、聚(羟基丁酸酯)、聚(膦嗪)、聚对苯二甲酸乙二酯、聚乙二醇、聚环氧乙烷、聚丙烯酰胺、聚丙烯酸羟乙基甲基酯、聚乙烯吡咯烷酮、聚乙烯醇、聚丙烯酸、聚乙酸酯、聚己内酯、聚丙烯、脂肪族聚酯、甘油、聚(氨基酸)、共聚(醚-酯)、聚亚烷基草酸酯、聚酰胺、聚(亚氨基碳酸酯)、聚亚烷基草酸酯、聚氧杂酯、聚原酸酯、聚磷腈以及其共聚物、嵌段共聚物、均聚物、共混物和组合。在一些实施例中,加强材料56由生物可吸收聚乙醇酸(PGA)形成。
参考图8-10,钉40中的每一个包括后跨部70和从后跨部70的相对端部延伸的间隔的支腿72。间隔的支腿72中的至少一个包括被配置成便于支腿72穿过组织“T”(图11)和加强材料56并且进入锁定材料58同时阻挡从锁定材料58去除支腿72的锁定结构74。在实施例中,支腿72中的每一个包括锁定结构74。
在实施例中,锁定结构74包括被配置成允许支腿72穿过组织和加强材料56到锁定材料58中同时阻挡支腿72从锁定材料缩回的成角度的齿76。在实施例中,齿76沿钉40的支腿72的长度的一部分放置并且由限定与钉支腿72的纵向轴线“X”成锐角β的远侧表面78和被配置成与锁定材料啮合互锁的近侧表面80限定。远侧表面78在近侧方向上向外逐渐变窄以允许钉支腿72穿透组织。在一些实施例中,近侧表面80基本上垂直于钉支腿72的纵向轴线“X”。然而,设想,近侧表面80可限定可与锁定材料58啮合或互锁以阻挡钉40从锁定材料58缩回的任何角度。
设想,锁定结构74可采用允许钉40的支腿72穿透组织同时抵抗钉支腿72从组织“T”(图11)缩回的多种配置。
参考图11-14,在使用圆形钉合装置10时,圆形钉合装置10的工具组合件16放置在组织“T”内,并且砧座组合件24相对于壳体组合件26移动到夹持位置以将组织“T”夹持在钉仓38和砧座头部组合件24的外壳50之间。更具体地说,组织“T”包括第一管状组织切片“T1”和第二组织切片“T2”。待接合的组织切片“T1”和“T2”的端部被夹持在钉仓38和砧座头部组合件24的外壳50之间。当启动钉合装置10以使推动器36在由图12中箭头“A”指示的方向上前进时,钉前进通过组织切片“T1”和“T2”,通过加强材料56并且进入锁定材料58。当在钉40的支腿72上的锁定结构74穿透到锁定材料58中时,锁定材料58与在钉支腿72上的锁定结构74啮合或互锁,以阻挡钉支腿72从锁定材料58并且因此从组织切片“T1”和“T2”缩回。因而,不再需要将钉仓38与砧座组合件24恰当地对准以恰当地形成钉40的要求。另外,也不需要通过将锁定材料58并入到砧座头部组合件44中使钉40变形。因而,用于启动钉合装置10的启动力最小化。如所说明,当启动钉合装置10时,刀37前进到在组织切片“T1”和“T2”之间的核心组织。
虽然本公开涉及圆形钉合装置,但是设想本公开可并入到包括内窥镜和敞开式线性和弯曲的钉合装置、具有依次启动钉的钉合装置和具有同时启动钉的钉合装置以及具有单独地启动钉的钉合装置的多种不同类型的钉合装置中。
所属领域的技术人员将理解,在本文中具体地描述且在附图中所说明的装置和方法是非限制性的例示性实施例。设想,在不脱离本公开的范围的情况下,结合一个例示性实施例说明或描述的元件和特征可与另一实施例的元件和特征组合。同样,所属领域的技术人员将了解基于上文所描述的实施例的本公开的另外特征和优点。因此,本公开不受特定地展示和描述的内容限制,而是由所附权利要求书规定。
