技术领域
本披露内容总体上涉及手术器械,并且具体涉及用于玻璃体视网膜手术的具有粘附优化边缘条件以增强玻璃体视网膜操作期间抓握和剥除视网膜层的镊子器械。
背景
玻璃体视网膜手术已经开发成用于恢复、保持并且增强遭受各种不同损伤及/或年龄相关退化状况的患者的视力。例如,使用包括玻璃体切除术操作的玻璃体视网膜操作来修复因诸如黄斑变性、糖尿病视网膜病变、糖尿病玻璃体出血、视网膜脱落的状况而造成的病患眼睛伤害,并且修复源自白内障手术的并发症并用于移除并修复因患者眼内异物造成的伤害。无损伤剥除患者眼睛内的内界膜(“ILM”)提高了成功玻璃体视网膜手术操作的机率。这些膜剥除或膜切除术操作基本上移除了覆盖视网膜的表面或上层ILM的多个部分以移除受损组织并抑制疤痕组织在患者眼睛的黄斑上生长,并且减小ILM对底层视网膜的牵引。
通常,为实施剥除操作,外科医生将使用非常精密的镊子,在高放大率下尝试抓握并从视网膜轻轻剥除ILM层。使用以金刚石粉打磨或其他方式处理的探针或器械来刮擦或牵拉视网膜组织或ILM层至可以由用于抓握并剥除ILM层的镊子来抓握的状态。然而,这样的作业是极其精巧的并且要求高精密度,因为在这样的剥除作业期间存在按压及/或捏夹ILM及底层视网膜组织过深的危险。而这样可导致可能的感染、流血、视网膜脱落并且可能是的底层视网膜层受伤害而促进白内障进展。通常,横跨黄斑形成的视网膜前膜复发一般在涉及这样的膜剥除手术的首次玻璃体视网膜手术后的约百分十患者中发生。
发明内容
简言之,本披露内容总体上涉及具有粘附优化边缘条件的手术器械。根据一个方面,本披露内容描述了镊子,该镊子包括本体、从该本体的第一端延伸的多个钳肢、形成在这些钳肢中的至少一者的远端的抓握表面、以及沿该抓握表面的至少一部分形成的纹理化表面。这些钳肢可以是可在打开构型与闭合构型之间移动的。该纹理化表面可以被构型成在这些钳肢移动成该闭合构型时与所接触的膜产生毛细作用。
本披露内容的另一方面涵盖玻璃体视网膜镊子,该玻璃体视网膜镊子包括:一对间隔开的弹性钳肢,这对钳肢可在打开构型与闭合构型之间移动;纹理化表面,该纹理化表面是沿每个钳肢的远端形成的,该纹理化表面包括间隔布置的多个空腔。该纹理化表面被构型成与邻接这些钳肢的膜产生粘附。该粘附是通过该膜填充该多个空腔而形成的。
这些不同方面可以包括以下特征中的一项或多项。该毛细作用可以是由基本上与粘附该膜相匹配的该纹理化表面的产生。该纹理化表面的表面形貌可以基本上是不均匀的。这些钳肢中的至少一者的远端包括圆化抓握边缘。该圆化抓握边缘可以包括在约500nm至约30,000nm的范围内的半径。这些钳肢中的至少一者的远侧尖端可以包括具有介于约25°与45°之间的角度的倒角尖端。该纹理化表面可以包括孔隙阵列以及布置在这些孔隙之间的多个峰部。
这些不同方面还可以包括以下特征中的一项或多项。该纹理化表面可以包括不规则形成的突起系列,这些空腔被限定在这些突起之间。限定在这些突起之间的空腔可以基本上是不均匀的。该多个空腔可以包括孔隙阵列,并且其中该纹理化表面进一步包括形成在这些孔隙之间的多个峰部。

详细说明
本披露内容描述了被构型成移除内界膜(“ILM”)的手术器械的多个不同的示例性实施方式。特别地,本披露内容描述了用于玻璃体视网膜手术操作中的示例性玻璃体视网膜镊子。特别地,本披露内容描述了适用于玻璃体切除术或膜剥除操作中的玻璃体视网膜镊子,在玻璃体切除术或膜剥除操作中ILM或其他膜被接合并且从视网膜剥除。玻璃体视网膜镊子经优化以使由该镊子施加到ILM的力的量和/或该镊子压入ILM的深度基本上最小化,而同时足以接合ILM以从视网膜移除。因此,该玻璃体视网膜镊子可操作来移除ILM而同时降低伤害或损伤底层视网膜组织的可能性。
参考图1至图3,镊子10可以包括长形本体11。在一些实例中,长形本体11可以由一对本体区段12A和12B形成。这些本体区段12A、12B可以被联接在一起以形成单一本体结构。在其他实施方式中,长形本体11可以是单一本体。长形本体11可以是由任何各种不同材料形成的。特别地,长形本体11可以是由医疗级材料形成的。例如,长形本体11可以是由金属形成的,诸如钛或不锈钢、镍钛合金或“镍钛诺”、或其他类似合金材料。另外,长形本体11可以是由聚合物形成的,诸如医疗级塑料;合成材料(例如,合成纤维或合成金刚石);或复合材料。而且,镊子10可以是单次使用后可丢弃的器械。可替代地,镊子10可以是可灭菌的,并且因此是可再使用的。
参考图2和图3,镊子10还包括一对钳肢13和14。这些钳肢13、14包括具有限定了钩状或C形构型的弯曲部分的远端17。这些钳肢13、14的远端17的弯曲性质容许接合表面27从这些钳肢13、14的剩余部分向内偏置。此外,由于远端17具有弯曲部分,这些接合表面27可以彼此对齐以便在这些钳肢13、14移动至闭合构型时基本上接合。
在这些钳肢13、14的远端17限定了抓握表面27。这些抓握表面27被适配成接合ILM或其他膜。而且,在接合和抓握ILM或其他膜时抓握边缘22也可能是重要的。这些抓握边缘22是这些钳肢13、14的外部表面的布置在这些抓握表面27与端表面15之间的部分。这些钳肢13、14还包括从端表面15沿这些钳肢13、14的弯曲部19延伸的外表面26。这些抓握表面27、抓握边缘22以及外表面26中的一者或多者可以是经增强以利于和/或优化其对ILM或其他膜的夹持及粘附的。
这些抓握边缘22可以是修圆的或者包括修圆的部分。在一些实例中,这些抓握边缘22的至少一部分的弯曲部可以具有50nm至30,000nm的半径。然而,在其他实例中,该半径可以大于或小于所阐明的范围。另外,在一些实例中,还可以增强外部表面15来促进与ILM或其他膜的粘附。
抓握边缘22的这种构型提供了对膜(如ILM)的改进的抓握。例如,在上文所标识的范围内的抓握边缘22(或其一部分)的半径提供了对膜的增强的抓握。在一些实例中,增强抓握减小了通过镊子施加到该膜上以成功抓握并移除该膜所必需的力。因此,可以降低与接合、抓握及移除膜相关联的风险。此外,如以下所解释的,这些抓握边缘22还可以包括纹理化表面。该纹理化表面进一步改进了对膜的粘附,从而进一步减小使该膜与镊子接合所需的力。再者,这些减小的力进一步改善了镊子的性能并且进一步降低了与抓握和移除膜相关联的潜在风险,例如对底层组织的危害。
图4示出了这些钳肢13、14的远端17的详细视图。特别地,图4示出了这些抓握表面27以及与ILM 60接合的抓握边缘22。在所展示的示例中,这些抓握表面27和抓握边缘22包括纹理化表面50。
经增强的表面可以经纹理化或按其他方式形成有粗糙化或图案化表面。这些抓握表面27以及在一些实例中这些抓握表面27和抓握边缘22两者被适配成在与其接合的膜上产生大的粘附力。纹理化表面50对这些抓握表面27和/或抓握边缘22提供了针对例如在剥除作业期间接合和抓握ILM 60或其他膜优化了的表面条件。在另外其他实施方式中,这些外部表面15、外表面26或这些表面的一个或多个部分中的一者或多者也可以包括纹理化表面(诸如纹理化表面50),以增强该表面与膜之间的粘附。
图5是图4中的位置A处所示出的纹理化表面50的详细视图。在图5所示出的示例中,纹理表面50包括多个凹陷或孔隙(下文统称为凹陷63)。该多个凹陷63可以基本上均匀地分布在预期表面上,例如,这些抓握表面27、抓握边缘22以及外部表面15中的一者或多者上。在一些实施方式中,这些凹陷63中的两者或更多者可以具有约100μm的间隔64以及约6μm的深度65。但在其他实例中,间隔64可以大于或小于100μm。此外,凹陷63的深度65可以大于或小于6μm。例如,在一些实例中,该多个凹陷63的间隔64和深度65可以基于有待接合的膜的具体类型、膜的敏感性或基于其他考量来选定。
纹理化表面50可以具有其他表面特征。例如,图6示出了其中纹理化表面50具有多个抬升凸出部66的详细截面视图。在一些实例中,这些凸出部66中的两者或更多者可以用约100μm的间隔64分离开。此外,这些凸出部66中的一者或多者可以具有约6μm的高度67。但在其他实例中,间隔64可以大于或小于100μm。此外,凸出部66的高度67可以大于或小于6μm。出于与上文所解释的相似的原因,这些凸出部66的间隔64和高度67可以基于有待抓握的膜的特性或与该膜相关联的其他考量(如位置、靠近其他敏感组织、或与该膜有关的其他方面)来选定。
虽然图5和图6示出了形成在纹理化表面50之上和/或之中的示例性特征,但本发明范围并非如此有限。例如,在一些实例中,纹理化表面50可以包括多个凹槽。图7示出了纹理化表面50的其中形成有多个凹槽68的部分。在一些实例中,这些凹槽68中的两个或更多个凹槽可以分开100μm。而且,这些凹槽68中的一者或多者可以具有6μm的深度。然而,如上文所解释的,这些凹槽的间隔和深度可以变化。
图8示出了具有多个脊69的示例性纹理化表面50。这些脊69可以沿该表面的一个或多个部分(如这些抓握表面27或抓握边缘22中的一者或多者)延伸。一些脊69的间隔和高度可以类似于上述间隔和高度,如间隔64和高度67。在一些实施方式中,纹理化表面50可以具有随机纹理。例如,如图9中所示,纹理化表面50可以包括随机分布的表面特征。例如,纹理化表面50可以包括脊、凹槽、凹陷、凸出部或其任何组合的随机网路。类似于上述示例性纹理化表面,图9中示出的纹理化表面50是基于有待抓握的膜的特性来构型的。
在另外其他实施方式中,纹理化表面50可以包括呈基本上均匀安排的在此所描述的两个或更多个不同的纹理。在其他实施方式中,纹理化表面50可以包括呈基本上随机安排的在此所描述的这些纹理中的两者或更多者。此外,纹理化表面50可以基本上全部包括单一类型纹理,其中这些特征的尺寸和/或间隔沿纹理化表面50变化。在另外其他实施方式中,纹理化表面50可以包括多个在此所描述的纹理,其中这些纹理的大小和/或间隔沿纹理化表面50变化。例如,这些纹理的选择和/或安排可以经选定来使由纹理化表面50产生的粘附力是针对所希望抓握的膜的类型而优化的。
此外,纹理化表面50可以具有1至10微米(即,1x 10-6m至10x 10-6m)的均方根(RMS)表面粗糙度。然而,在其他实例中,该RMS表面粗糙度可以大于或小于1至10微米。纹理化表面50的表面粗糙度可以基于该膜的特性(诸如上述考量中的一者或多者)而变化。
纹理化表面50可以是利用各种不同技术来形成的。例如,这些纹理化表面50可以通过蚀刻、电抛光、激光纹理化或其他粗糙化或纹理化技术来形成。其结果是,在一些实施方式中,这些抓握边缘22、抓握表面27、外部表面15、外表面26或其任何组合可以具备可操作以诱发毛细效应从而助长诸如ILM 60的上层61的膜与这些钳肢13、14的抓握边缘22、抓握表面27、外部表面15或外表面26之间粘附的表面粗糙度,如图4所展示出的。因此,创建了优化的夹持或粘附边缘条件,这使得能够将最小的接合力施加到ILM 60以及底层视网膜62上来增强镊子10与ILM 60之间的夹持和/或粘附。这种增强的夹持提供了改良的膜剥除同时基本上降低了损害底层组织的风险。
例如,如图1、图2、图10、图15、图17和图18所示,镊子10的钳肢13和14总体上从其近端16朝向其远端17向外偏离或张开,从而限定了打开构型。在该打开构型中这些钳肢13、14可以是偏置的。例如,可以通过形成这些钳肢13、14和/或长形本体11的材料的天然或固有弹性来提供这些钳肢13、14偏置成该打开构型。
这些钳肢13、14可移到至闭合构型,其中这些钳肢13、14的远端17被促使朝向彼此。在一些实例中,这些远端17在该闭合构型中发生接触。例如,在一些实施方式中,当这些钳肢13、14处于该闭合构型时,这些抓握表面27和/或抓握边缘22发生接触。在其他实例中,这些钳肢13、14的远端17形成闭合关系从而使这些抓握表面27和/或抓握边缘22在该闭合构型中彼此直接相邻但不接触,例如,如图3中所示。在该闭合构型中,这些抓握表面27可以用于接合和/或抓握ILM的顶层61的瓣片或其他部分。因此,可以利用镊子10来将ILM60从视网膜62剥除。
在其他实施方式中,如图10至图12中所示出的示例中,这些钳肢13、14的尖端21可以朝远侧方向渐缩。例如,在一些实例中,这些钳肢13、14的尖端21可以在两个方向上渐缩,如图10和图12所示。在其他实例中,这些钳肢13、14的尖端21可以仅在单一方向上渐缩。例如,这些钳肢13、14的尖端21可以在第一方向(例如,如图10中所示)上而不在第二方向(例如,如图12中所示)向远侧渐缩,或反之亦然。
图13示出了示例性钳肢13、14的远端的详细视图。这些钳肢13、14包括抓握边缘22,这些抓握边缘包括向内凸出的尖端23。这些钳肢13、14的抓握边缘22还可以包括凹陷35。因此,在一些实施方式中,这些钳肢13、14的抓握边缘22可以是对称的。在其他实施方式中,这些钳肢13、14的抓握边缘22可以是不对称的。图14示出了不对称的钳肢13、14的抓握边缘22。例如,钳肢13的抓握边缘22可以包括凸出部36,该凸出部被接纳在钳肢14的抓握边缘22的凹陷37内。
类似于上述示例,图13和图14中所示出的钳肢13、14还可以包括在这些抓握边缘22、端表面15或外表面26中的一者或多者上的纹理化表面,如上述纹理化表面50中的一者或多者。
再次参考图10至图12,这些钳肢13、14的远端还可以包括圆化远侧表面32。图11示出了图10中的位置B的细节,该细节示出了圆化远侧表面32。圆化远侧表面32可以具有弯曲半径,以限定出与视网膜形状相对应的形状。此外,这些抓握边缘22可以沿这些钳肢的弯曲尖端21连续延伸,如图12中所示。在图10至图12所示的示例中,这些弯曲尖端21限定了用于抓握膜(如ILM)的减小区域。在一些实施方式中,这些圆化远侧表面32、抓握边缘22或抓握表面27中的一者或多者可以包括纹理化表面,如上述纹理化表面中的一者或多者。
图15至图18展示了另一示例性镊子10。如图16中所示,这些尖端21可以经倒角化来限定抓握边缘22与纵向轴线43之间的角度θ。在一些实例中,角度θ可以是约25°至45°。然而,角度θ可以是任何所希望的角度。这些钳肢13、14的抓握表面27可以基本上是平坦的。
此外,如图17中所展示出的,这些钳肢13、14的外部表面15还可以形成角度在一些实例中,这些外部表面15相对于这些抓握表面27的角度可以是约25°至45°。然而,外侧表面44的角度可以布置成大于或小于此范围的角度。如上文所解释的,这些抓握边缘22、抓握表面27或外部表面15中的一者或多者可以包括纹理,如上述纹理化表面50中的一者或多者。
这些抓握边缘22、抓握表面27、外部表面15、和/或外表面26的形状可以经选定以进一步增强这些钳肢13、14的抓握性能。例如,这些特征中的一者或多者的几何形状可以经选定以增强抓握性能。此外,这些特征的几何形状以及施加到这些特征中的一者或多者上的纹理化表面50还可以经选定以增强(例如,优化)毛细作用,由此增强(例如,最大化)镊子10与特定膜之间的粘附。在选择纹理化表面50时还可以考量膜的特性,如膜的弹性和厚度。
镊子10与膜(如ILM)之间的增强吸引导致增强或增大的毛细力以致使膜(例如,ILM的顶层)环绕或围绕纹理化表面50的这些表面特征流动并且进入形成在这些抓握表面27之间的间隙中。此增强的毛细效应进而增大和/或增强了镊子10与ILM 60之间的粘附力。同时,增强的毛细效应使得能够在夹持及剥除ILM时以减小的施加到ILM和底层组织上的压力以及镊子10施加给ILM和底层视网膜的最小化的刮擦力来实施ILM剥除。因此,基本上降低了在剥除作业期间损伤这些底层组织(如视网膜)的风险。
参考图18,在一些实施方式中,在ILM 60的上层61中制成切口51之后,可以使用镊子10来刮擦并接合由切口51或ILM 60的其他部分形成的瓣片52以进行剥除。当这些抓握边缘22移动至与ILM 60在切口部位55处相接合时,可以使镊子10的外套56相对镊子10沿箭头57的方向移动。图2、图17和图18展示了套56的运行。套56接合这些钳肢13、14并且迫使这些钳肢13、14进入其闭合构型中。因此,这些钳肢13、14闭合并且接合ILM 60。参见图18,当朝向其闭合构型迫动钳肢13、14时,这些抓握边缘22单独地或与这些钳肢13、14的抓握表面27、外部表面15或外表面26相组合地接合ILM 60的一部分并将其向内刮擦或推进。ILM 60被牵拉并捏夹在这些抓握边缘22之间。此后,可以使用镊子10将ILM 60从底层视网膜62拉出或剥除。底层视网膜62不受影响并且保持基本上不接触,由此使对其造成的伤害最小化。当完成剥除时,可以使套56沿箭头58的方向移动。其结果是,套56脱离这些钳肢13、14,并且这些钳肢13、14固有地偏置进入打开构型导致这些钳肢13、14返回到打开构型,从而释放ILM。
以上描述总体上展示并描述了本披露内容的多种不同的示例性实施方式。然而,本领域技术人员应当理解可以对上述构造进行各种变化和修改而不脱离本披露内容的精神及范围。还预期以上描述中所含有的或附图中所示出的所有内容应解释为是说明性的而不应视为限制性的。此外,本披露内容的范围应当被理解成覆盖对上述示例的各种修改、组合、添加、替换等,它们应当被认为是在本披露内容的范围内。因此,如在此所论述的本披露内容的不同特征和特性可以选择性互换并且应用于本披露内容的其他经展示及未经展示的实施方式,并且可以对其加以许多变化、修改以及添加而不脱离所附权利要求书中所陈述的本披露内容的精神和范围。
