Description

用于手术器械的解剖尖端和导入构件
相关申请的交叉引用
本申请是于2007年9月7日提交的序列号为11/851,495的美国专利申请的部分持续申请,其全部内容通过引用合并于此。
技术领域
本公开通常涉及一种用于向组织施加手术紧固件的装置。本申请还涉及与手术紧固件施加装置一起使用的挠性引导件,以便于组织分离以及进入内部解剖结构。
背景技术
为了减少损伤和康复时间,许多手术操作通过皮肤中的小开口诸如切口或自然的体孔口得以执行。通常而言,这种操作被称为“内窥镜检查”,在患者的腹部上执行的操作除外,在该情形中,所述操作被称为“腹腔镜检查”。在整个本公开中,术语“微创”应该理解成包含内窥镜检查操作和腹腔镜检查操作两者。
在微创手术操作的过程中,通常使用手术紧固件施加装置来连接组织的相邻部分。各种各样这样的装置在本领域中是已知的,其中一些装置具体适用于特殊的手术操作,包括但并不局限于端端吻合、圆形端端吻合、开放式胃肠吻合、内窥镜胃肠吻合和横向吻合。合适的手术紧固件施加装置的实例在第5,915,616;6,202,914;5,865,361;和5,964,394号美国专利中被公开。典型地,这些手术紧固件施加装置包括第一构件,所述第一构件相对第二构件是可移动的,使得目标组织可定位在它们之间从而便于目标组织的抓紧和/或夹紧。
线性手术紧固件施加装置通常包括两个细长的钳夹构件,其中一个钳夹构件包括容纳多个手术紧固件的手术紧固件仓,所述多个手术紧固件呈两个以上线性排布置,另一个钳夹构件包括具有多个紧固件形成袋(pocket)的砧座部件,所述多个紧固件形成袋的构造和尺寸设置为在从手术紧固件仓弹射出紧固件时收纳手术紧固件且使手术紧固件成形。典型地,手术紧固件施加装置还会包括刀,所述刀能够在线性的手术紧固件排之间移动,从而在手术紧固件施加装置致动时同时或几乎同时地切割所连结和/或密封的组织。考虑到该性能,线性类型的手术紧固件施加装置通常用在手术操作中从而同时地密封和切割目标组织,例如患者的脉管系统、器官等。
并非罕见的是,某些附近组织(collateral tissue),例如脉管系统或其它结缔组织粘附到目标组织上,或以另外的方式与目标组织连结。因此,会期望包括能够将目标组织与这些粘附的附近组织分离的结构的手术紧固件施加装置便于在继续手术操作之前目标组织的隔离。
发明内容
在本公开的一个方案中,公开了一种手术紧固件施加装置,其包括:细长主体部,其具有近端和远端;末端执行器,其定位在细长主体部的远端处;以及导入构件。
末端执行器包括第一钳夹,第一钳夹可移动地联结至第二钳夹,从而使目标组织能够定位在第一钳夹与第二钳夹之间。末端执行器的第一钳夹包括砧座部件,末端执行器的第二钳夹包括手术紧固件仓,所述手术紧固件仓的构造和尺寸设置为将多个手术紧固件保持于其中。第一钳夹以具有接合结构的锥形的刚性尖端为终端。
导入构件包括近侧部和远侧部,并且其构造和尺寸设置为与末端执行器可释放地连接。导入构件至少部分地由挠性材料形成,并且其构造和尺寸设置为将目标组织与附近组织分离,从而将目标组织定位在末端执行器的第一钳夹和第二钳夹之间。导入构件在近侧部处具有联接结构,所述联接结构在构造和尺寸上对应第一钳夹的接合结构,从而便于导入构件与第一钳夹的可释放连接。
在手术紧固件施加装置的一个实施例中,可以想象到的是,导入构件的近侧部可由第一材料形成,而导入构件的远侧部可由具有更低硬度的不同的第二材料形成。
导入构件的近侧部可以是联接至导入构件的远侧部的独立部分(separatepart)。近侧部能够为具有用于摩擦地接合远侧部的脊状部的圆锥形构件。
在某些实施例中,第一钳夹包括砧座部件并且第二钳夹包括手术紧固件仓。手术紧固件仓的构造和尺寸设置为将多个手术紧固件保持于其中。第二钳夹构件可相对第一钳夹构件可枢转地安装。在某些实施例中,所述接合结构形成在砧座部件的尖端上。
为了便于将导入构件连接至末端执行器,可以想象到的是,导入构件的近侧部可包括空腔,所述空腔的构造和尺寸设置为至少部分地收纳第一钳夹和第二钳夹中的一个。为了增强导入构件和末端执行器之间的连接,包括在末端执行器上的接合结构和包括在导入构件上的联接结构的构造和尺寸可以设置为以卡扣配合的布置方式连接。例如,设置于末端执行器上的接合结构可以包括一个或多个凹槽,并且联接结构可以包括一个或多个止动件,所述止动件的构造和尺寸设置为可释放地定位在凹槽内。当被包括时,凹槽和止动件的构造和尺寸可以设置为在导入构件成功连接至末端执行器时向临床医生提供听觉或触觉指示。
在某些实施例中,导入构件的长度长于第一钳夹构件的长度。
在本公开的另一方案中,公开了一种手术紧固件施加装置,其包括:细长主体部,其具有近端和远端;末端执行器,其定位在细长主体部的远端处;连接构件,其具有近端和远端,且其构造和尺寸设置为与末端执行器可释放地接合;以及导入构件,其具有近侧部和远侧部,且其构造和尺寸设置为与连接构件可释放地接合。第一钳夹和第二钳夹中的一个以解剖尖端为终端,并且连接构件在解剖尖端处与末端执行器接合。
末端执行器包括第一钳夹,所述第一钳夹可移动地联结至第二钳夹,从而使目标组织能够定位在第一钳夹与第二钳夹之间。例如,第一钳夹可以包括砧座部件,并且第二钳夹可以包括手术紧固件仓,所述手术紧固件仓的构造和尺寸设置为保持多个手术紧固件。
连接构件的近端可以包括第一联接结构,并且连接构件的远端可以包括第二联接结构。为了便于将连接构件联接至末端执行器,可以想象到的是,末端执行器的第一钳夹和第二钳夹中的至少一个可以包括第一接合结构,例如在砧座部件上,所述第一接合结构的构造和尺寸与包括在连接构件的近端处的第一联接结构相对应。例如,解剖尖端包括第一接合结构。类似地,为了便于将连接构件连接至导入构件,可以想象到的是,导入构件的近端可以包括用于接合第二联接结构的第二接合结构。例如,可以预期的是,第一联接结构和第一接合结构的构造和尺寸可以设置为以卡扣配合的布置方式连接。另外,或可替代地,第一联接结构和第一接合结构的构造和尺寸可以设置为在连接构件与末端执行器成功连接时向临床医生提供听觉或触觉指示。
在某些实施例中,第一钳夹包括砧座部件并且第二钳夹包括保持多个手术紧固件的手术紧固件仓。解剖尖端可以形成第一钳夹的终端。第一接合结构可以形成在砧座部件上。
导入构件的构造和尺寸设置为:在将目标组织定位在末端执行器的第一钳夹和第二钳夹之间前,将目标组织与附近组织分离。为了便于导入构件和连接构件的连接,可以想象到的是,导入构件的近侧部可以包括空腔,所述空腔的构造和尺寸设置为至少部分地收纳连接构件的第二联接结构。还可以想象到的是,导入构件的近端可以至少部分地由挠性材料形成,从而连接构件的第二联接结构的收纳使得导入构件的近端向外扩展,进而在导入构件和连接构件之间产生过盈配合。在某些实施例中,连接构件限定了用于摩擦地接合导入构件的近侧部的脊状部。
在本公开的又一方案中,公开了一种与手术紧固件施加装置一起使用的挠性引导件,所述手术紧固件施加装置包括具有第一活动钳夹和第二活动钳夹的末端执行器,并且挠性引导件的构造和尺寸设置为:在将目标组织定位在第一钳夹和第二钳夹之间前,将目标组织与附近组织分离。挠性引导件长于第一钳夹和第二钳夹中的每一个,并且具有连接构件,所述连接构件的构造和尺寸设置为与末端执行器的解剖尖端和导入构件可释放地同时接合,从而使连接构件能够定位在末端执行器和导入构件之间。连接构件由比导入构件相对更坚硬的生物适应性材料形成。
在一个实施例中,可以想象到的是,连接构件可以包括具有第一联接结构的近端和具有第二联接结构的远端。在该实施例中,第一联接结构的构造和尺寸与第一接合结构相对应,所述第一接合结构与末端执行器的第一钳夹和第二钳夹中的至少一个相关,并且第二联接结构的构造和尺寸与第二接合结构相对应,所述第二接合结构与导入构件相关。导入构件可以至少部分地由挠性材料形成。
对本领域的技术人员来说,本公开的手术紧固件施加装置、导入构件和连接构件的这些以及其它特征将通过参考下面本公开的各个实施例的详细描述而变得更容易地显而易见。

具体实施方式
现在将参照附图对本公开的手术紧固件施加装置、导入构件、连接构件以及使用它们的方法的各个实施例进行详细描述,其中相同的附图标记标识类似或相同的元件。在附图以及下面的描述中,术语“近侧”应该理解成是指下面讨论的手术紧固件施加装置、导入构件或连接构件或它们的部件的在正确使用中较靠近临床医生的一端,而术语“远侧”应该理解成是指较远离临床医生的一端,这在现有技术中是传统和常规的。另外,术语“手术紧固件”应该理解成包括由生物适应性材料形成的任何基本刚性的结构,其适用于将组织连结在一起的预期目的,包括但并不局限于手术吻合钉、夹子等。而且,术语“组织”应该理解成是指任何人类或动物的组织、动脉、静脉、器官或其它在体内找得到的这种解剖结构。具体而言,这里术语“目标组织”的使用在下文中标识作为手术操作的目标或对象物的组织,而术语“附近组织”的使用是指目标组织周围的非手术操作的对象物的任何组织。
图1图示了可重复使用型或可丢弃型的手术紧固件施加装置10,其包括:手柄组件12,其具有活动手柄14和固定手柄16;细长轴18,其从手柄组件12向远侧延伸;末端执行器20,其定位在细长轴18的远端22处;以及导入构件100,其能够可释放地连接至末端执行器20。
在各个实施例中,可以想象到的是,手柄组件12可包括电动机驱动的、液压的、齿合的或其它这种机构,以便于手术紧固件施加装置10的致动。
通常而言,末端执行器20适于将相邻组织部分夹紧、紧固在一起并且沿着切割线切断。在使用过程中,手术紧固件施加装置10的接近和启动与其它已知的手术紧固件施加装置类似且一致。下面讨论手术紧固件施加装置10的接近和启动,包括手柄组件12和包含在内的驱动组件的部件和相互作用。但是,关于手术紧固件施加装置10的接近和启动的其它细节还可以通过参照共同转让的当前转让给Tyco医疗健康集团的第5,865,361号美国专利获得,所述专利的全部内容通过引用合并于此。
现在也参照图2-图6,末端执行器20包括第一钳夹24,所述第一钳夹24枢转地联结至第二钳夹26从而便于其的接近,并且适于将相邻组织部分夹紧、紧固在一起并且沿着切割线切断。末端执行器20的第一钳夹24包括砧座部件28,所述砧座部件28包括砧座板30(图2、图3)和砧座盖32(图3),并且第二钳夹26包括装载有多个手术紧固件36(图2、图4)的手术紧固件仓34(图2)。使活动手柄14(图1)朝向固定手柄16枢转使得第一钳夹24和第二钳夹26接近。在使得钳夹24、26接近之后,即使得钳夹24、26处于靠近的可操作布置之后,活动手柄14的继续枢转将多个手术紧固件36(图2、图4)从手术紧固件仓34(图2)弹射出,从而将多个手术紧固件36驱动到砧座板30中,由此成形为完形的手术紧固件,如下所述。下面还提供关于手术紧固件36的弹射的进一步细节。
可以想象到的是,手术紧固件仓34可以是可移除的并且可由另一装载仓替换。在其它实施例中,本公开可预期的是,末端执行器20可以构成用于手术紧固件施加装置10的可移除且可替换的装载单元的部件。
现在参照图4,装载到手术紧固件仓34(图2)中的每个手术紧固件36包括两条支腿38,所述两条支腿由在其间延伸的后跨部40连接。支腿38从后跨部40延伸至贯穿端42,所述贯穿端42的构造和尺寸设置为便于支腿38穿过组织。后跨部40和支腿38的尺寸能够变化,使得手术紧固件36可用于紧固具有各种特性的组织,诸如不同厚度的组织或包括疤痕组织的组织。
支腿38和后跨部40可以限定具有任何合适几何构造的剖面,包括但并不局限于矩形、椭圆形、正方形、三角形、梯形等。支腿38和后跨部40可呈现出相同的几何构造,如图4所示,或可替代地,支腿38和后跨部40可呈现出不同的几何构造。例如,支腿38可以呈现出矩形剖面,而后跨部40可以呈现出椭圆形剖面。
支腿38的贯穿端42可以是锥形的从而便于贯穿组织,或可替代地,贯穿端42可不包括锥形。在各个实施例中,可以想象到的是,贯穿端42可以限定圆锥形表面或平坦表面。
在成形之前,每个手术紧固件36的支腿38可以从后跨部40延伸出,使得支腿38基本平行。然而,在替代方案中,支腿38可以汇聚或从后跨部40分叉。
现在将特别地参照图1-图3和图6讨论砧座部件28(图3)。如上所述,砧座部件28包括砧座板30和砧座盖32。砧座板30是具有组织接触表面44(图5)的细长构件,其包括形成在其中的多个袋46。每个袋46定位成收纳手术紧固件36的支腿38(图4)并使支腿38变形,从而实现成形的构造。更特别地,形成在砧座部件28中的每个袋46包括两个成形表面48(图5),所述成形表面48延伸至砧座部件28中即远离组织接触表面44,从而限定深度“D”,如图6中最佳所示。在支腿38与成形表面48接合时,成形表面48沿着箭头“A”的方向(图5)向内引导支腿38从而便于手术紧固件36变形为标准“B”形构造(图7)。在替代实施例中,可以想象到的是,形成在砧座板30的组织接触表面44中的袋46的构造和尺寸可以设置为使手术紧固件36变形从而在成形时实现单环(single-loop)构造或其它形状。应该意识到的是,用于袋46的其它构造和尺寸在此也是可预期的,从而手术紧固件36在成形时可呈现出其它构造。
袋46设置为布置在延伸通过砧座板30的狭槽50(图2、图5)的相反两侧的排。狭槽50被构造成容纳刀52(图2)或其它这种切割元件的移动,从而便于沿着切割线切断组织。尽管在替代实施例中将狭槽50描述成纵向延伸通过砧座板30,但是可以想象到的是,狭槽50可限定为呈角度的、弓形或其它形状的构造。狭槽50可以沿着砧座板30的中心线延伸,如图2和图5图示的实施例中所示,或可替代地,狭槽50可偏离砧座板30的中心线。
在图2和图5中所示的砧座板30的实施例中,形成在组织接触表面44中的袋46布置成一对内排54A、一对中间排54B和一对外排54C(图4)。一对内排54A在狭槽50的外侧横向间隔开并且最靠近狭槽50,一对中间排54B在一对内排54A的外侧横向间隔开,并且一对外排54C在一对中间排54B的外侧横向间隔开且最远离狭槽50。虽然砧座板30被描述成包括三对排,即相应的各对内排54A、中间排54B和外排54C,但是包括更少数量和更多数量排的袋46的砧座板30的替代实施例都没有超出本公开的范围。
现在参照图3,砧座盖32包括外表面56并且相对砧座板30固定,从而在砧座盖32与砧座板30之间没有相对移动。例如,可以想象到的是,砧座盖32可以以卡扣配合的布置方式或任何其它适用于与其建立紧固连接的预期目的的方式经由一个或多个焊接点紧固至砧座板30。
第二钳夹26包括手术紧固件仓34和沟道66。现在将参照图2对手术紧固件仓34进行描述。手术紧固件仓34包括仓主体58,所述仓主体58具有一对侧壁60、底壁62和顶壁64,并且手术紧固件仓34处于第二钳夹26的沟道66中。在所图示的实施例中,仓主体58包括延伸通过的狭槽68,所述狭槽68被构造成容纳刀52的纵向移动。如上关于砧座部件28所讨论的,虽然狭槽68被描述成纵向延伸通过手术紧固件仓34,但是在替代实施例中,狭槽68可限定为呈角度的、弓形或其它形状的构造。狭槽68的位置对应延伸通过砧座板30的狭槽50的位置,使得狭槽68和狭槽50对准。狭槽68可沿着手术紧固件仓34的中心线延伸,如图3所示,或可替代地,狭槽68可与手术紧固件仓34的中心线间隔开。
仓主体58的顶壁64包括基本平面的构造以及多个保持狭槽68,所述基本平面的构造相对砧座板30的组织接触表面44(图5)基本平行延伸。保持狭槽68布置成排,位置与形成在砧座板30的组织接触表面44中的成排袋46(图5)相对应。相应地,在如图2所示的手术紧固件仓34的特定实施例中,保持狭槽68布置成一对内排72A、一对中间排72B和一对外排72C,每一对都布置在狭槽68的相反两侧。一对内排72A在狭槽68的外侧横向间隔开并且最靠近狭槽68,一对中间排72B在一对内排72A的外侧横向间隔开,并且一对外排72C在一对中间排72B的外侧横向间隔开且最远离狭槽68。虽然手术紧固件仓34被描述成包括三对排,即相应的内排72A、中间排72B和外排72C,但是包括更少数量和更多数量的成排紧固件保持狭槽68的手术紧固件仓34的替代实施例都没有超出本公开的范围。
每个紧固件保持狭槽68的构造和尺寸设置为收纳手术紧固件36(图2、图4),以及定位于紧固件保持狭槽68中的对应尺寸的推动器74(图2)。在使用过程中,通过滑块(sled)76(图3)向上、即朝向仓主体58的顶壁64驱动推动器74以与手术紧固件36接合,从而将手术紧固件36从保持狭槽68中弹射出,如下面进一步详细讨论的。当手术紧固件36从紧固件保持狭槽68中脱离时,它们在组织中产生的切割线的相反两侧成排部署,例如在所图示的实施例中部署为内排、中间排和外排。
现在参照图1和图8-图10,将对本公开的导入构件的一个实施例进行描述,其由附图标记100来标识。导入构件100包括相应的近端102和远端104,并且由挠性的生物适应性材料形成,包括但并不局限于聚合材料,诸如橡胶或塑料。在一个特定实施例中,可以想象到的是,导入构件100可以整体都由挠性材料形成。但是,可替代地,可以想象到的是,导入构件100可包括由更高硬度材料形成的刚性增大的部分,从而为导入构件100提供额外的结构,和/或有助于组织的分离。
导入构件100的开放式近端102的构造和尺寸设置为便于放置在末端执行器20的远端20A上。例如,如图8和图9中所图示的,导入构件100的近端102的构造和尺寸可以设置为放置在砧座部件28的周围,或可替代地,近端102的构造和尺寸可以设置为放置在手术紧固件仓34的周围。为了便于将导入构件100连接至末端执行器20以及与末端执行器20断开,可以想象到的是,导入构件100的近端102可以包括导圆角的边缘“E”,如图10所示。
在一个实施例中,可以想象到的是,导入构件100可以可操作地连接至手术紧固件施加装置10的手柄组件12(图1),使得导入构件100可由临床医生来操控。例如,导入构件100可经由一个或多个挠性构件(未示出)诸如电缆、导线等可操作地连接至手柄组件12,所述挠性构件联接在沿着导入构件100的长度的多个点处,使得挠性构件的操纵会导致导入构件100的对应移动。例如,挠性构件可以联接至导入构件100,使得挠性构件的近侧缩回导致导入构件100在预定位置的弯曲或挠曲,从而使临床医生选择性地重新构造导入构件100,以及在目标组织“T”(图10)和附近组织“C”之间有效地操控导入构件100。
导入构件100的构造和尺寸设置为适于引导末端执行器20进入作为手术操作的对象物的目标组织“T”(图10)和目标组织“T”周围的任何附近组织“C”之间的位置。为此,导入构件100可包括部分或完全弯曲的构造,其限定了基本上在近似5°至近似90°的范围内的弓形。在一个实施例中,例如,如图8和图9所示,导入构件100从砧座部件28朝向手术紧固件仓34弯曲,并且比钳夹长,使得目标组织以一定角度靠近手术紧固件施加装置的钳夹并且在钳夹之间定向。但是应该意识到的是,导入构件100可以任何适用于将器械引导就位和/或便于目标组织“T”与任何附近组织“C”分离的预期目的的方向弯曲。
另外,导入构件100包括朝向远端104逐渐变细的细长轮廓,如图1和图9-图11所示。包括锥形轮廓允许导入构件100的远端104在相比于其更近侧的部分时限定减小的剖面面积,从而便于导入构件100被推进穿过患者的组织。另外,导入构件100的远端104处减小的剖面面积便于进入内部空间和组织中(所述内部空间和组织对于给定更大尺寸的末端执行器20(图1)会是难以进入的),并且减小了手术紧固件施加装置10向远侧推进对患者的内部组织的影响。例如,在一个实施例中,可以想象到的是,导入构件100的远端104可以具有在近似2mm至近似6mm的范围内的横向尺寸,但是更大和更小的尺寸也不会超出本公开的范围。
导入构件100可具有任何适用于无损伤地将目标组织“T”(图10)与任何附近组织“C”分离的预期目的的剖面构造,从而便于手术紧固件施加装置10(图1)进入患者的内部组织和器官中。例如,导入构件100可具有椭圆形的剖面构造(参见图13)、基本导圆角的剖面构造或多边形的剖面构造。
现在将参照图1-图10结合导入构件100对手术紧固件施加装置10(图1)的使用和操作进行描述。如上所提及的以及图1所示的,手柄组件12包括活动手柄14。活动手柄14可操作地连接至致动轴(未示出),所述致动轴收纳控制杆的近端,从而致动轴的线性推进导致控制杆对应的线性推进。控制杆可进一步与包括细长驱动梁78(图2)的轴向驱动组件接合,所述细长驱动梁78具有构造和尺寸设置为支撑刀52的远端。如上所讨论的,滑块76向上驱动推动器74,驱动紧固件36抵靠砧座部件28的袋46。刀52定位在驱动梁78上以在滑块76的后方平移。驱动梁78包括上凸缘79A和下凸缘79B,所述上凸缘的构造和尺寸设置为沿着砧座板30的顶表面移动,所述下凸缘的构造和尺寸设置为沿着沟道66的外侧移动,同时驱动梁移动通过砧座部件的狭槽50和沟道66的狭槽68。
首先,导入构件100连接至末端执行器20(图1、图8、图9),即导入构件100定位在砧座部件28或手术紧固件仓34的周围。之后,能够操纵手术紧固件施加装置10(图1)的组件和导入构件100,使得导入构件100的远端104定位在目标组织“T”(图10)和附近组织“C”之间。在导入构件100的操纵过程中,构成导入构件100的挠性材料允许导入构件100促使附近组织“C”逐渐地远离目标组织“T”,从而建立和/或扩大如下通路:末端执行器20能够沿着所述通路行进。
为了便于将目标组织“T”(图9)定位在砧座部件28和手术紧固件仓34之间,例如经由之前提及的挠性构件(未示出)(如果包括的话)向近侧缩回或拉回导入构件100的远端104。以该方式操纵导入构件100而将目标组织“T”引导至砧座部件28和手术紧固件仓34之间的位置,同时防止附近组织“C”与手术紧固件施加装置10的任何部件的非期望接触。
在确定已按照期望将目标组织“T”定位在砧座部件28和手术紧固件仓34之间,并且确定附近组织“C”没有定位在手术紧固件施加装置10(图1)致动时会导致目标组织“T”或附近组织“C”的损害的位置之后,能够将导入构件100从末端执行器20移除。之后,利用手柄组件12使钳夹24、26(图1)接近以将目标组织“T”(图9)夹紧在钳夹24、26之间,并且向钳夹24、26施加压缩力。具体而言,活动手柄14的操纵使得致动轴推进从而实现控制杆的对应推进。在特定实施例中,致动轴包括限定在其上的齿条,并且活动手柄14具有安装在其上的棘轮爪用于步进式地(incrementally)接合致动轴以及使致动轴前进。棘爪可安装在枢销上,并且可设置盘绕式扭簧以使棘爪偏置为与齿条接合。控制杆在其远端处连接至轴向驱动组件,所述轴向驱动组件包括之前提及的驱动梁78(图2),这样控制杆的远侧移动影响驱动梁78的远侧移动,这依次促使砧座部件28(图2)朝向手术紧固件仓34移动。具体而言,控制杆使得驱动梁78向远侧推进,从而上凸缘79A横向通过砧座板30的顶表面,并且下凸缘79B横向通过延伸通过手术紧固件仓34的沟道66。
随着组织被牢固地夹紧在钳夹24、26(图1、图2)之间,启动手术紧固件施加装置10从而弹射出手术紧固件36(图2)。手术紧固件施加装置10的接近和启动与其它已知的手术紧固件施加装置类似并且一致,其它已知的手术紧固件施加装置诸如在共同转让的当前转让给Tyco医疗健康集团的第5,865,361号美国专利中所公开的手术紧固件施加装置,所述专利的全部公开内容在此通过引用合并于此。具体而言,操纵活动手柄14以使驱动组件推进,这使得滑块76(图2)横向通过仓主体58并且接合推动器74,从而将多个手术紧固件36从手术紧固件仓34中弹射出。在滑块76向远侧推进的过程中,其成一定角度的引导表面顺序接触包括在推动器74上的凸轮表面。滑块76的引导表面和推动器74的凸轮表面之间的相互作用促使推动器74朝向仓主体58的顶壁64移动,从而将手术紧固件36从形成于仓主体58中的保持狭槽68中弹射出。手术紧固件36的顺序发射持续,直到滑块76推进到手术紧固件仓34的远端,此时所有容纳在手术紧固件仓34内的手术紧固件36将已被弹射出。
在弹射过程中,多个手术紧固件36通过保持狭槽68以穿过目标组织“T”进而与限定在砧座部件28的组织接触表面44中的袋46(图2、图5)接合。手术紧固件36与袋46的接合使手术紧固件36成形,从而连接目标组织“T”(图9)的相邻部分。
现在参照图11-图48,将对本公开的导入构件的替代实施例进行讨论。下面所讨论的导入构件的每个实施例类似于之前描述的导入构件100,因此将仅对与其有任何不同的部分进行讨论。
具体参照图11-图14,将对由附图标记200标识的导入构件的实施例进行讨论。导入构件200可以整体或部分是空心或实心的,并且包括开放式近端202和闭合式远端204。当构造成实心构件时,开放式近端202的内表面可以定形为抵接砧座部件28(图3)的外表面,从而为导入构件200提供稳定性以及支撑。
为了便于导入构件200在目标组织“T”(图9)和附近组织“C”之间的远侧推进和定位(navigation),可以想象到的是,导入构件200可包括双锥形(dual taper)。具体而言,导入构件200可包括锥形轮廓,所述锥形轮廓的剖面高度和宽度从近端202向远端204减小。
导入构件200的开放式近端202的构造和尺寸设置为适合便于与末端执行器20(图1、图12)的可滑动接合和脱离。例如,导入构件200的开放式近端202的构造和尺寸可以设置为摩擦地接合手术紧固件仓34,如图13所示,或可替代地,导入构件200的开放式近端202的构造和尺寸可以设置为例如以类似于上面关于导入构件100(图1-图11)所讨论的方式的方式摩擦地接合砧座部件28(图3)。
为了在手术紧固件施加装置10(图1)致动之前不必移除导入构件200的情况下确保末端执行器20(图1、图12)的合适操作,可以想象到的是,导入构件200的定位在砧座部件28(图12)和手术紧固件仓34之间的部分可具有小于砧座部件28和手术紧固件仓34之间的设计间隙的厚度,由此在手术紧固件施加装置10致动时抑制与砧座部件28的干涉。另外或可替代地,可以想象到的是,导入构件200的近端202可包括切口(未示出),所述切口可定位在砧座板30和手术紧固件仓34之间。
为了便于与末端执行器20(图1、图12)接合和脱离,可以想象到的是,导入构件200可包括粘合剂,或可替代地,导入构件200可包括如下结构:其构造和尺寸设置为与形成在末端执行器20上的对应结构接合。例如,导入构件200可包括诸如突起206(图13)的结构,所述突起形成在近端202内的相对表面上,所述结构的构造和尺寸设置为接合末端执行器20上的对应结构,例如与形成在仓主体58的侧壁60中的槽口80接合。典型地,形成在仓主体58的侧壁60中的槽口80的构造和尺寸设置为与第二钳夹26(图1)上的对应结构(未示出)接合,从而有助于手术紧固件仓34的牢固放置。在本实施例中,在使用过程中,导入构件200定位在手术紧固件仓34的远端的周围,直到处于导入构件200的近端202内的突起206接合槽口80。为了移除导入构件200,临床医生施加足以使导入构件200的近端202变形的力,使得近端202向外挠曲,从而使突起206脱离槽口80。接下来,能够将导入构件200从手术紧固件仓34中移除。
可以想象到的是,导入构件200可包括一个或多个凹槽部、切口等(未示出),以便抑制与末端执行器20的活动结构诸如形成在手术紧固件仓34上的凸缘81(图12)的干涉。在手术紧固件仓34的图示的实施例中,凸缘81的构造和尺寸设置为随着砧座部件28逐渐被夹紧而朝向手术紧固件仓34的远端纵向且可滑动地移动,以使在末端执行器20内生成的夹紧力平衡。
尽管上面已经对将本公开的导入构件作为手术紧固件施加装置10(图1)的可移除部件的每个实施例进行了讨论,但是还可以想象到的是,导入构件100、200中任一个均可与末端执行器20一体形成,使得导入构件100、200不会与末端执行器20分开。
如上关于导入构件100(图1-图10)所讨论的,可以想象到的是,导入构件200可经由诸如电缆、带子等的联接件可操作性地连接至手术紧固件施加装置10的手柄组件12(图1),从而便于导入构件200选择性地重新构造。
除了易操控之外,还可以想象到的是,导入构件200可以相对末端执行器20(图1、图12)的联接有导入构件200的部件偏置以达成弯曲构造(图12),所述部件诸如砧座部件28(图12)或手术紧固件仓34,或可替代地,导入构件200可朝向线性位置(图12)偏置。
现在将参照图13-图15将对由附图标记300标识的本公开的导入构件的实施例进行讨论。在某些操作中,某些脉管系统或者其它粘附结缔、连结或其它的组织粘附目标组织(即要吻合和切断的组织)或与目标组织连结。如果这样的组织在进入目标组织、分离组织以及将手术紧固装置引导就位之前必须分离,从而使目标组织定向在钳夹之间同时避开附近组织,有利的是在钳夹的其中一个上包括解剖部分或解剖尖端85。在特定的优选实施例中,解剖尖端85是刚性的锥形尖端,其与手术紧固装置的砧座部件一体形成或者联接到其上。这样的解剖尖端85能够在图16中看到。期望解剖尖端85是弯曲的或成角度的以便靠近手术紧固件仓34,从而当成一定角度靠近组织时使组织定向在钳夹之间。
导入构件300包括限定空腔304的近端302,所述空腔的构造和尺寸设置为至少部分地收纳砧座部件28(图2、图3)的解剖尖端。如图13-图15中所图示的,例如,空腔304的构造和尺寸设置为收纳砧座部件28的一部分,更具体而言,砧座部件28(图1、图3、图15)的可选择的解剖部83或尖端85。导入构件300为手术紧固件装置提供了挠性且较长的引导件并且延伸装置的通路,同时朝向目标组织逐渐地引导装置。相比于刚性的解剖尖端,导入构件300是挠性的,从而为用户提供了如何靠近组织的更多选择。如果用户愿意,导入构件300能够联接至解剖尖端或移除,使得解剖尖端能够用于靠近、进入以及分离组织,同时引导组织在钳夹之间就位。
为了便于导入构件300和末端执行器20(图1)之间的连接,导入构件300的近端302包括联接结构306(图13),所述联接结构的构造和尺寸设置为与包括在末端执行器20(图1)的解剖部上例如包括在图16所示的实施例中的解剖部83或尖端85上的对应接合结构82(图15)可释放地连接。为了建立和保持与末端执行器20的连接,可以想象到的是,包括在导入构件300的近端302处的联接结构306可由不同于构成导入构件300的剩余部分的材料形成。在一个具体实施例中,例如,可以想象到的是,联接结构306可由如下材料形成:所述材料的硬度高于构成导入构件300的剩余部分的材料的硬度。
继续参照图13-图15,在本公开的一个实施例中,联接结构306(图13、图14)和接合结构82(图15)的构造和尺寸设置为以卡扣配合的方式接合。更具体而言,联接结构306包括一个或多个隆起的突起308,所述突起向内延伸至空腔304中,并且接合结构82包括一个或多个凹槽84,所述一个或多个凹槽84的构造和尺寸对应突起308。可以预期的是,突起308和凹槽84的特殊构造和尺寸可以为使得:在导入构件100和末端执行器20成功连接时向临床医生提供听觉或触觉指示。
突起308和凹槽84可以具有适用于在导入构件300和末端执行器20(图1)之间建立可释放连接的预期目的的任何几何构造。例如,可以预期的是,突起308可被构造成一个或多个隆起的肋状物310(图13),并且凹槽84可被构造成一个或多个对应的线性沟道85(图15)。可替代地,突起308可被构造成一个或多个半球状凸出部312(图16),并且凹槽84可被构造成一个或多个对应的腔体92(图17)。
现在将参照图1和图13-图15结合导入构件300对用手术紧固件施加装置10(图1)紧固组织的方法进行讨论。在将手术紧固件施加装置10(图1)插入到患者体内之前,导入构件300(图14、图15)连接至末端执行器20(图1),例如连接至砧座部件28(图3)的解剖部83(图1、图3、图16)。在连接时,包括在导入构件300的近端302处的联接结构306(图14、15)与包括在解剖部83(图16)上的对应接合结构82(图16)或末端执行器20的其它部件紧密配合。
在装配之后,将手术紧固件施加装置10(图1)插入到患者的组织中,并且使手术紧固件施加装置10向远侧推进穿过患者的组织。在向远侧推进的过程中,导入构件300无损伤地分离患者的内部组织和器官从而为临床医生提供到目标组织“T”(图9)的通路。当到达目标组织“T”时,临床医生可选择例如通过切口移除导入构件300,或可替代地,可以将导入构件300留在适当位置。当留在适当位置时,构成导入构件300的挠性材料允许导入构件300在操纵过程中弯曲和挠曲,从而在不损伤患者的内部组织的情况下容纳导入构件300的移动。然后临床医生对手术紧固件施加装置10(图1)定向,从而将目标组织“T”(图9)布置在末端执行器20的打开的钳夹24、26(图1)之间。在将目标组织“T”按照期望定位后,利用手柄组件12使钳夹24、26接近从而将目标组织“T”夹紧在钳夹24、26之间,并且启动手术紧固件施加装置10从而将手术紧固件36(图2)从手术紧固件仓34中弹射出,如上所讨论的。在穿过目标组织“T”之后,使手术紧固件36通过与砧座板30接合而成形以实现成形的构造,从而联接目标组织“T”的相邻部分。在将手术紧固件36从手术紧固件仓34中弹射出的过程中,目标组织“T”同时或近似同时地由之前提及的刀52(图2)来切断,所述刀在滑块76的后方位置即其近侧与驱动梁78相应地移动。
现在参照图18和图19,在本公开的替代实施例中,设置连接构件400以将手术紧固件施加装置10(图1)例如砧座部件28与结合图14和图15讨论的导入构件300连接。
连接构件400由适于在手术操作的过程中与患者的内部组织接触的生物适应性材料诸如聚合材料或不锈钢形成,并包括相应的近端402和远端404。连接构件400的构造和尺寸设置为与砧座部件28或末端执行器20的其它这种部件以及导入构件300可释放地接合,从而便于将导入构件300可操作地联接至末端执行器20。具体而言,如图18和图19所示,连接构件400的近端402与末端执行器20(图1)例如砧座部件28的解剖部83是可接合的,使得连接构件400从砧座部件28向远侧延伸,并且连接构件400的远端404与导入构件300的近端302是可接合的,使得导入构件300从连接构件400向远侧延伸。
如图19所示,在连接构件400的一个实施例中,其近端402包括内部空间406,所述内部空间406的构造和尺寸设置为至少部分地收纳砧座部件28的解剖部83。为了便于连接构件400和砧座部件28之间的连接,连接构件400的近端402包括近侧联接结构408,所述近侧联接结构408的构造和尺寸设置为与之前描述的包括在解剖部83上的接合结构82可释放地连接,接合结构82的构造和尺寸与近侧联接结构408对应。尽管在图18和图19中图示为解剖部83的一部分,但是如上所讨论的,应该意识到的是,接合结构82可与砧座部件28(在本公开的替代实施例中,或为手术紧固件仓34(图2))的任何其它部分相关。
在图18和图19所示的连接构件400的实施例中,近侧联接结构408被图示为包括向内延伸至内部空间406中的一个或多个隆起的突起410,所述突起410的构造和尺寸设置为与形成在砧座部件28的解剖部83上的凹槽84接合。但是在本公开的替代实施例中,近侧联接结构408和接合结构82可呈现适用于在连接构件400和末端执行器20(图1)之间产生可释放连接的预期目的的任何构造或尺寸。如上关于导入构件100(图1-图11)所讨论的,可以预期的是,联接结构408和接合结构32的特殊构造和尺寸可以为使得,在连接构件400成功连接至末端执行器20时为临床医生提供听觉或触觉指示。
为了便于连接构件400和导入构件100之间的接合,连接构件400的远端404包括远侧联接结构412,所述远侧联接结构412的构造和尺寸设置为部分或完全地由空腔304(图19)收纳,所述空腔304被包括在导入构件300的近端302处。
在一个实施例中,可以想象到的是,远侧联接结构412可包括例如具有环形构造的一个或多个突起(未示出),所述突起的构造和尺寸设置为与一个或多个凹槽(未示出)接合,所述一个或多个凹槽形成在导入构件300的近端302处的空腔304中,使得远侧联接结构412可以卡扣配合或摩擦配合的布置方式与导入构件300的近端302接合。如结合形成在连接构件的近端402处的联接结构408和形成在末端执行器20(图1)上的接合结构82所提及的,远侧联接结构412和空腔304的构造和尺寸可设置为,在连接构件400成功连接至导入构件300时为临床医生提供听觉或触觉指示。
但是可替代地,如图18和图19所示,远侧联接结构412可包括一系列锥形部414,所述锥形部414的尺寸逐渐减小从而在相邻的锥形部414相交的位置处限定脊状部416。在本实施例中,随着远侧联接结构412由空腔304收纳,构成导入构件300的挠性材料允许锥形部414使得导入构件300的近端302向外扩展,从而在导入构件的近端302和连接构件400的远侧联接结构412之间产生过盈配合。在扩展之后,脊状部416以保持导入构件300相对连接构件400的位置的方式接合空腔304的内表面,直到期望断开。
现在参照图1、图18和图19,将结合导入构件300和连接构件400对利用手术紧固件施加装置10(图1)来紧固组织的方法进行讨论。在将手术紧固件施加装置10(图1)插入到患者的组织中之前,将连接构件400的近端402联接至末端执行器20,例如砧座部件28的解剖部83,并且将导入构件300连接至连接构件400的远端404。在连接时,连接构件400的近侧联接结构408与包括在解剖部83上的对应接合结构82紧密配合,并且将连接构件400的远侧联接结构412插入到限定在导入构件300的近端302中的空腔304中,使得脊状部416接合空腔304的内表面从而保持导入构件300和连接构件400的相对位置。
在装配之后,将手术紧固件施加装置10(图1)插入到患者的组织中并且向远侧推进穿过患者的组织,在该期间导入构件300无损伤地将目标组织“T”(图9)与任何附近组织“C”分离,从而为手术紧固件施加装置10提供到目标组织“T”的通路。
当到达目标组织“T”时,临床医生可选择移除导入构件300和连接构件400,或将它们留在适当位置,如之前所提及的。然后根据以上所讨论的,临床医生能够继续进行目标组织“T”的抓紧、紧固和切割。
现在参照图20,将对由附图标记500标识的本公开的导入构件的另一实施例进行讨论。导入构件500包括近端502和远端504。导入构件500的近端502由至少部分弹性的材料形成,并且包括具有相应的第一分支部506和第二分支部508的Y形构造。分支部506、508的构造和尺寸设置为便于与手术紧固件施加装置10(图1)的末端执行器20可释放地接合,例如与砧座部件28(图2、图3)或手术紧固件仓34(图2)中的任一个可释放地接合。具体而言,导入构件500的分支部506、508包括联接结构510,所述联接结构510的构造和尺寸设置为与包括在末端执行器20上的接合结构82可释放地连接。虽然在所图示的实施例中接合结构82被示出为形成在末端执行器20的砧座部件28上,但是应该意识到的是,可替代地,联接结构510的构造和尺寸可以设置为与形成在手术紧固件仓34(图2)上的结构接合。另外,尽管导入构件500的分支部506、508被图示为它们的构造和尺寸设置为便于与接合结构82的连接,所述接合结构82定位在末端执行器20的侧部87上,在替代实施例中,但是可以想象到的是,接合结构82可被包括在末端执行器20的上部和下部上,并且相应地可对导入构件500的分支部506、508的构造和尺寸进行设置。
在图20所图示的导入构件500的实施例中,包括在分支部506、508上的联接结构510包括一对突起512,所述突起512被构造成弓形止动件514,并且包括在砧座部件28上的接合结构82被构造成对应构造和尺寸的凹槽84。但是应该意识到的是,在本公开的替代实施例中,联接结构510和接合结构82在不脱离本公开的范围的情况下可以呈现其它几何构造。
导入构件500的远端504包括细长轮廓,所述细长轮廓的构造和尺寸设置为便于导入构件500无损伤地向远侧推进穿过患者的组织。远端504包括挠性而弹性的材料,其允许远端504在必要时弯曲和挠曲,从而允许临床医生将导入构件500定位在目标组织“T”(图9)和附近组织“C”的周围而不会引起非必要的损伤。
在将导入构件500施加到砧座部件28上时,联接结构510搭在末端执行器20的外表面上,这导致分支部506、508沿着箭头1指示的方向略微地向外张开。但是,在将联接结构510定位在接合结构82内时,构成近端502的弹性材料允许分支部506、508回到它们正常的构造,由此使得分支部506、508以压入配合的布置方式来接合末端执行器20。为了将导入构件500与末端执行器20断开,临床医生向导入构件500施加预定力从而将联接结构510与接合结构82分离。例如,临床医生能够向远侧拉动导入构件500,或者相对末端执行器20旋转导入构件500,从而促使止动件514离开凹槽84。
在如图21所示的导入构件500的替代实施例中,可以想象到的是,除了联接结构510以外,导入构件500的分支部506、508还可包括枢转构件516,从而便于将导入构件500与末端执行器20分离。在本实施例中,当期望将导入构件500与末端执行器20脱离时,将径直向内即沿着箭头2所标识的方向的力围绕枢转构件516施加给分支部506、508。围绕枢转构件516向分支部506、508施加力使得分支部506、508围绕枢转构件516弯曲,从而分支部506、508的更近侧部分向外张开,即沿着箭头1所指示的方向向外张开,由此将联接结构510从接合结构82中释放出来,并且允许移除导入构件500。
再次参照图20,可以想象到的是,包括联接结构510的导入构件500的近端502可由第一材料形成,而导入构件500的远端504可由不同的第二材料形成。例如,第一材料的硬度可比第二材料大。相对于柔性更大的材料,在导入构件500的近端502包含具有更大硬度的材料便于联接结构510和接合结构82之间更牢固的连接。构成导入构件500的远端504、同时比构成近端502的材料更富挠性的材料足够地坚硬,从而便于目标组织“T”(图9)以上述方式与附近组织“C”分离。
在本公开的一个实施例中,可以想象到的是,导入构件500的远端504可包含具有高可视色例如红色、绿色、黄色等的材料,以便增强导入构件500在内部工作空间内的可视性。
现在参照图22-图24,在本公开的一个实施例中,可以想象到的是,砧座部件28的解剖部83可包括尖端600,所述尖端紧固在砧座板30(图23、图24)和砧座盖32(图22)之间。如图23所示,尖端600包括弓形的远侧部602,所述远侧部602的构造和尺寸设置为便于目标组织“T”(图9)与任何附近组织“C”的分离。尖端600可由包括但并不局限于聚合材料的任何合适的生物适应性材料通过诸如模制的任何合适工艺形成。
尖端600经由柱604、铆钉等紧固至砧座板30,柱604、铆钉等延伸通过形成在尖端600和砧座板30中的对应开口(未示出)。将柱604穿过尖端600和砧座板30放置之后,以前述方式例如经由一个或多个焊接点将砧座盖32(图22)紧固至砧座板30。
现在参照图25-图27,将对由附图标记600′标识的尖端的替代实施例进行讨论。尖端600′基本类似于关于图22-图24所讨论的尖端600,因此将仅对与其有任何不同的部分进行讨论。
将尖端600′穿过形成在砧座部件28的远端28A中的开口92(图25)而插入到砧座部件28中。如上关于尖端600(图22-图24)所讨论的,当相对砧座部件28合适定位时,尖端600′定位在砧座板30(图26、图27)和砧座盖32(图25)之间。代替上述柱604(图24)或除上述柱604以外,尖端600′包括突块(tab)606,所述突块606的构造和尺寸设置为定位在形成于砧座板30中的狭槽50内,从而抑制尖端600′与砧座部件28不经意地断开。具体而言,突块606的构造和尺寸设置为与由狭槽50限定的远侧壁93(图25、图26)接合。突块606和狭槽50的远侧壁93的接合防止尖端600′相对砧座部件28移动超出预定位置。
为了进一步便于将目标组织“T”(图9)与任何附近组织“C”分离,可以想象到的是,可以连同在此描述的本公开的导入构件的任一实施例,例如图28中由附图标记700标识的导入构件,来使用尖端600(图22-图24)、600′(图25-图27)。
导入构件700包括限定空腔704的近端702,所述空腔704的构造和尺寸设置为便于与砧座部件28(参见图25)的远端28A联接。但应该意识到的是,空腔704的构造和尺寸可设置为与导入构件700的替代实施例中的手术紧固件仓34(图2)接合。为了便于将导入构件700联接至砧座部件28,导入构件700包括定位在近端702的内壁708上的联接结构706。联接结构706延伸进入空腔704中,并且包括多个突起710。尽管突起710被图示为包括限定多个齿712的构造,但应该意识到的是,突起710的替代构造没有超出本公开的范围,例如具有弓形构造的突起。
为了进一步增强导入构件700和砧座部件28之间的连接,可以预期的是,砧座部件28例如解剖部83可包括粗糙表面88。虽然在所图示的实施例中粗糙表面88已被图示为形成在砧座部件28上,但是可替代地,粗糙表面88形成在手术紧固件仓34(图2)上以便在期望时增强导入构件700和手术紧固件仓34之间的连接。粗糙表面88可包括适合便于与导入构件700的近端702(图28)联接的任何结构。例如,如图29所示,粗糙表面88可包括表面涂层89,或可替代地,如图30所示,粗糙表面88可包括玻璃刀表面磨光(glass-bit surface finish)90。
为了便于将砧座部件28插入到限定在导入构件700的近端702中的空腔704中,可以想象到的是,同样如图30所示,砧座部件28可包括抛光尖端91。抛光尖端91用于减小砧座部件28和导入构件700的近端702之间的摩擦,从而允许砧座部件28足以推进到空腔704中来便于联接结构706和粗糙表面88的接合。
现在参照图31-图33,图示了本公开的由附图标记800标识的导入构件的实施例。导入构件800包括近端802和远端804,并且其构造和尺寸设置为相对末端执行器20(图1)例如砧座部件28纵向移动。更具体而言,导入构件800的构造和尺寸设置为可滑动地移动通过形成在砧座盖32中的狭槽94,从而导入构件800可以在缩回位置(图31、图32)和推进位置(图33)之间选择性地重新定位。在缩回位置处,导入构件800的远端804靠近砧座部件28的最远侧尖端95的近侧定位,而在推进位置处,导入构件800的远端804在砧座部件28的最远侧尖端95的远侧定位,从而便于将目标组织“T”(图9)与任何附近组织“C”分离。
为了便于在缩回位置和推进位置之间移动,可以想象到的是,导入构件800可包括手动构件806,所述手动构件806的构造和尺寸设置为由临床医生接合。在导入构件800的一个实施例中,手动构件806从导入构件800向上延伸,并且可定位在导入构件800的近端802处,如图31-图33所示,或可定位在任何其它合适的位置。可替代地,手动构件806可包括粗糙表面(未示出),所述粗糙表面没有从导入构件800向上延伸,而是沿着砧座盖32(图3)的平面延伸。
为了提高临床医生操纵导入构件800的能力,可以想象到的是,导入构件800可连接至末端执行器20(图1),从而允许其横向移动,例如从一侧移动到另一侧,并且允许其纵向移动。例如,如图34和图35所示,导入构件800可经由枢转构件808连接至砧座部件28,使得导入构件800沿着箭头1和2所指示的方向是可移动的。允许纵向和横向两种移动为临床医生提供了到内部空间的增大的入口,这允许临床医生在将导入构件800定位于患者的内部组织周围的过程中精确地放置导入构件800。
图36-图38图示了由附图标记900标识的导入构件的另一实施例。导入构件900包括具有支脚904的一对挠性翼状物902,所述翼状物的构造和尺寸设置为牢固地接合砧座部件28,例如砧座盖32。例如,可以想象到的是,支脚904的构造和尺寸可以设置为以卡扣配合的方式接合砧座部件28。导入构件900还包括轨式部(rail)906(图37、图38),所述轨式部的构造和尺寸设置为定位在形成于砧座板30中的狭槽50内。轨式部906包括壁908,所述壁908的构造和尺寸设置为与由狭槽50限定的远侧壁93接合,从而抑制导入构件900相对砧座部件28向远侧移动超出预定位置,进而降低与砧座部件28不经意断开的可能性。在砧座部件28处于与目标组织“T”(图9)相邻的期望位置之后,在启动手术紧固件施加装置10(图1)之前,能够通过将支脚904与砧座盖32分离来将导入构件900从砧座部件28中移除。例如,翼状物902能够向外横向变形,例如通过使导入构件900相对砧座部件28旋转。
图39和图40图示了由附图标记1000标识的本公开的导入构件的另一实施例。通过枢转构件1002和一个或多个枢转板1004将导入构件1000安装在砧座部件28上,所述枢转构件延伸通过导入构件1000,所述枢转板紧固至末端执行器20的外表面。枢转构件1002可以是适合便于导入构件1000横向枢转运动,即沿着箭头1(图39)所指示的方向从一侧移动到另一侧的预期目的的任何构件,包括但并不局限于螺钉、铆钉等。
可以想象到的是,可连同各种构造的末端执行器20使用导入构件1000。例如,可以想象到的是,导入构件1000可连同具有基本线性构造(参见图41)的砧座部件28来使用,或可替代地,连同包括之前提及的解剖部83的砧座部件28来使用,如图40所示。
在图41和图42中图示了由附图标记1100标识的导入构件的另一实施例。导入构件1100包括近端1102和远侧部1106,所述近端具有凸边(collar)1104且所述凸边1104构造和尺寸设置为定位在砧座盖32的周围,远侧部1106的构造和尺寸设置为便于将目标组织“T”(图9)与任何附近组织“C”分离。凸边1104的构造和尺寸设置为接合砧座部件28,从而在其间的相对纵向移动基本得以抑制。例如,可以想象到的是,凸边1104可包括至少部分弹性的材料,允许凸边1104在与砧座部件28产生关联时向外变形,从而便于与砧座盖32卡扣配合地连接。
为了进一步增强导入构件1100和砧座部件28之间连接的稳定性,可以想象到的是,导入构件1100的远侧部1106可包括一个或多个突块1108、搭扣(snap)、突起等,所述突块的构造和尺寸设置为与砧座部件32中的对应结构接合,如图41所示。
现在参照图43,将对由附图标记1200标识的导入构件的另一实施例进行讨论。导入构件1200包括包含联接结构1204的近端1202、具有防止损伤的尖端部1208的远端1206,以及细长主体部1210。如图43所图示的,导入构件1200的细长主体部1210可包括锥形构造以便于将目标组织“T”(图9)与任何附近组织“C”分离。
导入构件1200的近端1202的构造和尺寸设置为插入到形成于砧座部件28的远端28A处的开口92中,使得导入构件1200可定位在砧座盖32(图3)和砧座板30之间。为了便于将导入构件1200联接至砧座部件28,可以想象到的是,导入构件1200的近端1202和砧座部件28的远端28A可包括对应结构,所述对应结构的构造和尺寸设置为配合式接合。例如,在图43所示的实施例中,可以想象到的是,包括在导入构件1200的近端1202处的联接结构1204的构造和尺寸可以设置为与对应接合结构96连接,所述对应接合结构96以压入配合的布置方式形成在砧座部件28的远端28A处的开口92内。在所图示的实施例中,联接结构1204被图示为包括多个突起1212,并且接合结构96被图示为包括对应构造和尺寸的凹槽97。但应该意识到的是,用于联接结构1204和接合结构96的替代构造没有超出本公开的范围。
尽管导入构件1200被图示为包括类似于解剖部83(图1、图3、图15)的构造,但在本公开的替代实施例中,可以想象到的是,导入构件1200也可以呈现其它构造。例如,如图43A所示,导入构件1200可包括类似于以上关于图1-图10所讨论的导入构件100的更加细长的构造。
现在参照图44,在一个实施例中,包括在导入构件1200的近端1202处的联接结构1204可包括联接有头部1216的柄杆1214,所述柄杆的构造和尺寸设置为定位在形成于砧座部件28的远端28A处的开口92(图43)内。为了便于将联接结构1204保持在开口92内,包括在砧座部件28的远端28A处的接合结构96可包括一对在其间限定间隙“G”(图45)的肩部98。间隙“G”的横向尺寸大于柄杆1214的横向尺寸,但是小于头部1216的横向尺寸,从而防止导入构件1200与砧座部件28不经意地断开。
为了在内部工作空间内操纵的过程中便于导入构件1200的推进和控制,可以想象到的是,砧座部件28的远端28A可由第一材料形成,第一材料例如是刚性材料,诸如实心或片状的金属,导入构件1200可由更富挠性的第二材料形成,第二材料诸如为塑料或橡胶。为了进一步增强导入构件1200和砧座部件28之间连接的稳定性,可以想象到的是,包括在导入构件1200的近端1202处的联接结构1204可以被热熔至砧座部件28的远端28A。
图46图示了由附图标记1300标识的本公开的导入构件的另一实施例,所述导入构件包括近侧部1302和远侧部1304。导入构件1300的近侧部1302包括外层1306和内层1308,以及空腔1312,外层1306和内层1308在其间共同限定了腔体1310,所述空腔1312的构造和尺寸设置为收纳末端执行器20(图1),例如砧座部件28(图2、图3)或手术紧固件仓34(图2)。导入构件1300还包括通道1314,所述通道纵向延伸通过导入构件1300且与腔体1310和包括在导入构件1300的远侧部1304上的孔口1316流体连通。通道1314允许流体诸如空气或盐水通过孔口1316并且流入到腔体1310中,从而使腔体1310充满且膨胀。可以想象到的是,孔口1316可包括密封件(未示出)、阀等从而抑制流体脱离腔体1310和/或孔口1316,直到期望腔体1310收缩的时刻。
在使腔体1310膨胀之前,导入构件1300的近端1302处的空腔1312限定了比由末端执行器20的要联接导入构件1300的部件限定的横向尺寸小的横向尺寸,例如比砧座部件28或手术紧固件仓34的横向尺寸小的横向尺寸。但是,在随着腔体1310充满流体而使腔体1310膨胀时,空腔1312的横向尺寸增加,使得末端执行器20或其部件可定位在空腔1312内。在将导入构件1300的近端1302连接至末端执行器20之后,临床医生能够通过排出膨胀流体而可选择地缩小腔体1310。在此还可预期的是,腔体1310内的流体可向外层1306和内层1308施加压力,并且该压力可以被传输至末端执行器20(图1)的外表面,由此有助于将导入构件1300的近侧部1302保持在末端执行器20的周围。
为了适应腔体1310的扩张和收缩,可以想象到的是,构成导入构件1300的近侧部1302的外层1306和内层1308的一个或两个可以由弹性材料形成,例如具有相对低硬度的材料,诸如收缩制管材料(shrink tubing)。
图47图示了由附图标记1400标识的本公开的导入构件的另一实施例。导入构件1400包括近侧部1402和远侧部1406,近侧部1402包括选择性可变形部分1404,远侧部1406可定位在可变形部分1404的周围。
可变形部分1404包括弹性构件1408,所述弹性构件1408由可变形诸如延展性材料形成,其能够由临床医生手动地重新构造,从而呈现出期望的几何构造。例如,可以想象到的是,弹性构件1408可包括挠性轴1410,如图47所示,所述挠性轴1410直接或可操作地连接至末端执行器20。在所图示的实施例中,挠性轴1410经由联接结构1412连接至末端执行器20,所述联接结构1412与末端执行器20一体形成或可从末端执行器20上释放,例如在砧座板30(图3)和砧座盖32之间。
导入构件1400的远侧部1406由至少部分弹性的材料形成,从而在手术操作过程中便于导入构件1400无损伤地推进,由此导入构件1400能够有效地定位在目标组织“T”(图9)和任何附近组织“C”的周围,而不会引起非必要的损伤。远侧部1406包括内部腔体1414,所述内部腔体1414的构造和尺寸设置为收纳可变形部分1404。远侧部1406可以任何合适的方式联接至近侧部1402,诸如通过包含弹性材料。包含弹性材料允许远侧部1406被作用向可变形部分1404和/或联接结构1412上,从而近侧部1402和远侧部1406以压入配合的布置方式彼此接合。可替代地,可以想象到的是,近侧部1402和远侧部1406可包括对应结构,所述对应结构的构造和尺寸设置为可释放地配合式接合,诸如在此结合以上所讨论的导入构件的各个替代实施例所描述的。
尽管导入构件1400被图示为包括细长构造,所述细长构造类似于关于上述图1-图10所讨论的导入构件100的细长构造,但是在本公开的替代实施例中,可以想象到的是,导入构件1400可呈现出其它构造。例如,如图49所示,导入构件1200可包括类似于解剖部83(图1、图3、图15)的构造的构造。
虽然已经结合末端执行器20(图1)对本公开的导入构件的每个实施例进行了讨论和图示,末端执行器20适合用于执行组织的手术吻合紧固的腹腔镜检查操作,但是导入构件可适于与任何手术器械一起使用,所述手术器械适用于将多个手术紧固件36(图2)施加到组织的一部分的预期目的,之后沿着切割线来切断组织。
可替代地,本公开的导入构件可适于与手术吻合装置3000(图49)一起使用,诸如在共同转让的当前转让给Tyco医疗健康集团的第7,334,717号美国专利中所公开的,所述专利的全部内容在此通过引用合并于此。手术吻合装置3000包括仓收纳半部3002以及砧座半部3004,所述仓收纳半部3002容纳多个手术紧固件。在使用过程中,半部3002、3004经由手柄3006、3008枢转地连接以接近。
在半部3002、3004接近之后,通过经由启动杆3012的推进而向远侧驱动启动滑动部3010来启动手术紧固件施加装置3000。启动滑动部3010的远侧移动使得多个凸轮杆接合凸轮表面,所述凸轮表面与多个推动器相互作用从而将多个手术紧固件从仓收纳半部3002排出。手术紧同件定位在轨道(track)的任一侧,所述轨道在纵向移动过程中引导刀,从而沿切割线切断组织。
