优先权要求
本申请主张2013年6月6日提交的标题为“变换式灌注/抽吸装置(TransformerIrrigation/Aspiration Device)”的美国临时专利申请第61/831,665号的优先权益，其发明人为G.Lamar Kirchhevel和Charles Kittridge Beauvias，该申请的全部内容以引用的方式并入本文中，其引用程度如同全面和完整地在本文中阐明。
发明领域
本发明大体涉及外科手术装置。更具体地说，但不作为限制，本发明涉及灌注/抽吸装置。
相关技术描述
白内障手术可包括移除浑浊天然晶状体和周围皮质以及用透明的人工晶状体将其替换。移除天然晶状体可包括使用(用于晶状体超声乳化和移除、)通电的、灌注的、振动尖端，然后使用用于皮质移除的灌注和抽吸尖端。
先前的(Predicate、)皮质移除装置包括同轴和双手动装置。单手操作的同轴装置可包括由灌注套筒包围的抽吸尖端。两手操作的双手动装置可包括两个单独的器械：一个提供灌注插管并且另一个提供抽吸插管。同轴装置可包括两个管道连接件，一个用来提供灌注流体，并且一个用于抽吸真空，而双手动装置可包括在灌注插管装置上的用于灌注流体的管道连接件、和在抽吸插管装置上的用于真空的单独管道连接件。
概述
在各种实施方案中，插管装置可通过将组成插管装置的抽吸手持件部分和灌注手持件部分耦接(用于同轴)和断开耦接(用于双手动)而在同轴模式与双手动模式之间进行变换。在一些实施方案中，灌注手持件部分和抽吸手持件部分可包括用于将抽吸手持件部分的远端可释放地耦接到灌注手持件部分的近端的互锁元件。
在同轴模式下，抽吸手持件部分可耦接至灌注手持件部分，以便通过在灌注手持件部分上的第一抽吸尖端将流体抽吸到主切口中，并且随后通过在抽吸手持件部分上的第二抽吸尖端(第二抽吸尖端至少部分地位于与第一抽吸尖端流体连通的灌注手持件部分内侧、)进行抽吸。在同轴模式下，可通过灌注手持件部分上的灌注流体出口来提供灌注流体。在一些实施方案中，灌注流体出口可以是耦接到灌注手持件部分的远端的灌注套筒中的端口。灌注套筒可至少部分地包围从灌注手持件部分延伸的第一抽吸尖端。
在双手动模式下，可将抽吸手持件部分与灌注手持件部分断开耦接，以便通过(置于第二切口中的、)第二抽吸尖端提供抽吸，同时灌注手持件部分继续通过(在主切口中的、)灌注流体出口提供灌注流体。在双手动模式下，灌注手持件部分可不通过第一抽吸尖端提供抽吸。
在一些实施方案中，插管装置还可包括处于灌注手持件部分的近端中的密封件，密封件被配置来在抽吸手持件部分耦接到灌注手持件部分时接收第二抽吸尖端。在一些实施方案中，密封件为锥形并且被配置来配合在灌注手持件部分的远侧部分内，以使得密封件的各个壁压靠在灌注手持件部分的内壁上，从而阻止密封件的各个壁与灌注手持件部分的内壁之间的流体流动。在一些实施方案中，密封件可包括O形环，O形环被配置来压靠在灌注手持件部分的内壁上，以便阻止O形环与灌注手持件部分的内壁之间的流体流动。在一些实施方案中，密封件可被配置来在将抽吸手持件部分从灌注手持件部分移除时阻止离开灌注手持件部分的抽吸流体流出。在一些实施方案中，插管装置还可包括保持器，保持器用于在将抽吸手持件部分插入灌注手持件部分以及从灌注手持件部分抽出时将密封件保持在灌注手持件部分中。
在一些实施方案中，抽吸手持件部分的抽吸尖端可插入到在灌注手持件部分中的密封件中，以便将抽吸手持件部分的抽吸尖端布置成与灌注手持件部分的抽吸路径流体相通，从而使得进入灌注手持件部分上的抽吸尖端的流体经过灌注手持件部分的内部、进入抽吸手持件部分的抽吸尖端并且随后离开抽吸手持件部分。一旦尖端被插入，就可将抽吸手持件部分耦接到灌注手持件部分以便形成同轴手持件。将抽吸手持件部分耦接到灌注手持件部分可包括将抽吸手持件部分和灌注手持件部分上的互锁元件旋拧在一起。在耦接之后，同轴手持件随后可通过灌注手持件部分上的抽吸尖端提供抽吸，并且通过灌注手持件部分上的灌注流体出口提供灌注流体。为了将插管装置设置成双手动模式，可将抽吸手持件部分与灌注手持件部分断开耦接，并且可将抽吸手持件部分的抽吸尖端从灌注手持件部分中的密封件中抽出，从而形成两个单独的手持件。随后，可通过灌注手持件部分上的灌注流体出口提供灌注流体，同时通过抽吸手持件部分上的抽吸尖端提供抽吸。在一些实施方案中，通过灌注流体出口提供灌注流体可包括通过在耦接到灌注手持件部分的远端的灌注套筒中的端口提供灌注流体(灌注套筒可至少部分地包围灌注手持件部分上的抽吸尖端、)。

实施方案的详述
在一些实施方案中，眼科灌注/抽吸插管装置101可支持同轴模式(单手操作)和双手动模式(两手操作)两者。插管装置101可被配置来在单个同轴手持件(如图1a至图1c中所示)与分开的双手动手持件(如图1d中所示、)之间进行变换。在两种模式下，可通过在套筒107中、位于灌注手持件部分103的远端133处的灌注流体出口端口129提供灌注流体(例如，提供到眼睛中的第一切口中、)。在同轴模式下，可通过在套筒107中的第一抽吸尖端111提供抽吸，而在双手动模式下，可通过在分开的抽吸手持件部分105上的第二抽吸尖端109(例如，插入到眼睛中的第二切口中、)提供抽吸。在一些实施方案中，在双手动模式下时，可不通过第一抽吸尖端111提供抽吸。当插管装置101被组装用于同轴模式时，抽吸路径可以是串联穿过第一抽吸尖端和第二抽吸尖端，其中第一抽吸尖端111处于套筒107内侧并且第二抽吸尖端109处于插管装置手柄(其至少部分地由灌注手持件外壳体121形成、)内侧。流体最初可进入第一抽吸尖端111的远端417中的孔，流过抽吸管117，由手柄内侧的第二抽吸尖端109进行抽吸，并且随后穿过在抽吸手持件部分105的近端137上的连接器115离开插管装置101。
在一些实施方案中，对于双手动操作来说，可通过使抽吸手持件部分105与灌注手持件部分103断开耦接并且将抽吸手持件部分105从灌注手持件部分103移除来将插管装置101分成两个手持件(即，灌注手持件部分103和抽吸手持件部分105、)。例如，如图1d中所见，可以旋拧抽吸手持件部分105以便将抽吸手持件部分105上的接片123与灌注手持件部分103中的狭槽125脱离接合，并且随后轴向拉动抽吸手持件部分105以便将抽吸手持件部分105与灌注手持件部分103分开。在一些实施方案中，可以在不增加、移除或改变管道连接件或移除套筒107的情况下将插管装置101变换成两个单独的手持件。在抽吸手持件部分105与灌注手持件部分103分开的情况下，随后可将第二抽吸尖管109插入穿过眼睛中的次级切口以便进行抽吸(例如，以便能够移除切口下方的皮质、)。在一些实施方案中，可通过将抽吸手持件部分105耦接到灌注手持件部分103而将插管装置101变换回用于同轴操作的整体式手持件。例如，可将抽吸手持件部分105的第二抽吸尖端109插入到灌注手持件部分103的近端131中，并且随后可旋拧抽吸手持件部分105以使接片123与狭槽125接合，从而将抽吸手持件部分105锁定到灌注手持件部分103。在一些实施方案中，接片123和狭槽125可被设定尺寸来在将抽吸手持件部分105旋拧到灌注手持件部分103上以便接合接片123和狭槽125时提供摩擦配合。也可设想其他接合机构(例如，接片和狭槽扣合配置、管中管摩擦配合等、)。
如图2a中所见，在一些实施方案中，插管装置101的灌注手持件部分103中的止回阀201可在灌注手持件部分103和抽吸手持件部分105分开时阻止流体离开灌注手持件部分103，但可在灌注手持件部分103和抽吸手持件部分105耦接在一起时允许穿过尖端109的流体连通。在一些实施方案中，O形环203可在灌注手持件部分103和抽吸手持件部分105耦接在一起时进一步防止抽吸流体在止回阀201周围、在灌注手持件部分103与抽吸手持件部分105之间流动。在一些实施方案中，止回阀201和O形环203可以是弹性体(例如，由聚合物制成、)。也可设想用于止回阀和O形环的其他材料。在一些实施方案中，在灌注手持件外壳体121的内壁中的浅槽213(例如，参见图2a、)可接收抽吸管117上的对应肋状物501(参见图5、)，以使抽吸管117在灌注手持件外壳体121内对齐并将其保持在灌注手持件外壳体121内，并且以便阻止抽吸管117在灌注手持件外壳体121内旋转。在一些实施方案中，抽吸管117可以是光滑的并且不包括肋条501。在一些实施方案中，灌注手持件外壳体121的内壁可以是光滑的(即，不包括浅槽213、)，并且抽吸管117与灌注手持件壳体121的内壁可具有摩擦配合。例如，抽吸管117上的肋状物501可被配置来当抽吸管117插入其中以便在抽吸管117与灌注手持件壳体121之间提供固定的摩擦配合时抵靠灌注手持件壳体121的内壁进行挤压。
图2b示出灌注手持件部分103和抽吸手持件部分105的替代实施方案。图2b示出具有比图2a所示更小的基座部分的止回阀201的不同轮廓。如图2b中所示，止回阀201可包括轴向O形环203，其中O形环的一侧上的平坦面面向抽吸管117上的对应平坦面。O形环203的背离平坦面的圆形部分可被配置来在抽吸手持件部分105耦接到灌注手持件部分103时轴向地抵靠抽吸手持件部分105进行按压和密封。
如图3a至图3b中所见，在一些实施方案中，止回阀201可以是锥形，在止回阀201的尖端中具有孔口207以便抽吸尖端109穿过。在一些实施方案中，孔口/尖端接口可以是紧贴的，以便在将抽吸尖端109插入到孔口207中时阻止抽吸流体在抽吸尖端109周围流动。此外，孔口207可在将抽吸尖端109抽出时闭合或在尺寸上减小，以便在不存在抽吸尖端109时阻止流体流过减小的孔口。例如，如图3c所示，孔口207可被配置为缝隙207a，其中在将抽吸尖端109抽出时，缝隙207a的两侧合到一起以防止流体穿过孔口207。孔口207还可包括如图3d中所示的两个交叉缝隙207b。也可设想其他孔口形状(例如，孔口207可成形为如图3e中所示的小圆形孔口207c、)。如图3f至图3g中所见，在一些实施方案中，止回阀201可包括具有铰接折板301的小圆形孔口207c。铰接折板301可由横向缝隙303(如图3f至图3g的横截面中所见的横向)形成。铰接折板301可充当折板阀以便在不存在抽吸尖端109时关闭形成密封件。存在于抽吸管腔211中的任何流体的压力也将作用来将铰接折板301按压至闭合。孔口207c可具有一定深度(如图所示、)以允许横向缝隙303的轴向位置的更大容差。
在一些实施方案中，止回阀201可包括抵靠抽吸管117的内壁在灌注手持件部分103内侧匹配的侧壁。止回阀201的侧壁与抽吸管117的内壁之间的紧贴配合可阻止止回阀201与抽吸管117的内壁之间的抽吸流体流动。O形环203可通过进一步阻止O形环203与抽吸管117的内壁之间流体流动而提供对流体流动的另外的障碍。在一些实施方案中，O形环203和止回阀201可由单一部件形成(在一些实施方案中，O形环203和止回阀201可以是单独的部件、)。
在一些实施方案中，当抽吸手持件部分105与灌注手持件部分103分开时，卡扣式保持器205可将O形环203和止回阀201固定在灌注手持件部分103中。如图4a至图4b中所见，在组装期间，可以将止回阀201和O形环203插入到抽吸管117中，然后使用可具有扣合到狭槽403中的接片401的卡扣式保持器205。如图4c中所见，在一些实施方案中，子槽405被设定大小用于接片401，以便在接片401稍微变形并且随后如图4d所见扣合回到狭槽403中之前滑入。如图2a中所见，一旦被安装，卡扣式保持器205就可阻止止回阀201和O形环203的移除。在一些实施方案中，卡扣式保持器205可抵接O形环203，或可与O形环203稍微隔开。如在图2b的替代实施方案中所示，止回阀201可不使用卡扣式保持器205(例如，当移除抽吸手持件部分105时，O形环203与灌注手持件外壳体121的各侧壁之间的摩擦配合可将止回阀201保持在灌注手持件外壳体121内、)。
如图5中所见，抽吸管117可包括另外的O形环119。如图6a至图6b中所见，O形环119可在抽吸管117与灌注手持件外壳体121之间提供摩擦配合。当O形环119/抽吸管117组件插入到灌注手持件外壳体121中时，O形环119可在内侧压缩灌注手持件外壳体121中的对应凹部并且与其形成流体紧密密封件。在一些实施方案中，流体紧密密封件可阻止从连接器113进入灌注手持件部分103的灌注流体离开灌注手持件部分103的近端131。灌注流体可从连接器113进入灌注手持件部分103，并且在O形环119与套筒107之间的抽吸管117的外侧周围流动。肋状物407(如图4a中所见、)可将抽吸管117的远端415与灌注手持件外壳体121的各内壁间隔开，以便形成用于灌注流体的通道。随后，灌注流体可流过开口411并且在拧入抽吸管117的远端415中的抽吸尖端111周围流动。套筒107可扣合到或拧到灌注手持件外壳体121的脊409上，并且从连接器113接收灌注流体。随后，灌注流体可通过灌注流体出口(例如，端口129、)离开套筒107。
如图7a至图7d中所见，抽吸手持件部分105可形成专用于对第二切口进行抽吸的单独手持件部分。流体可通过抽吸端口701进入抽吸尖端109(在双手动模式和同轴模式两者期间、)。抽吸手持件部分105上的抽吸尖端109被示为弯曲的，但也可设想其他形状(例如，直的、成角度的等。、)在一些实施方案中，如图2a中所见，弯曲的抽吸尖端109可以是弯曲的或成角度的，以便到达眼睛中的各种解剖结构。在一些实施方案中，弯曲的抽吸尖端109也可朝向抽吸管117的底壁弯曲或成角度，以便更容易地到达被吸入到抽吸管腔211中的抽吸流体(然而，插管装置101也将利用直的抽吸尖端109在同轴模式下起作用、)。在一些实施方案中，抽吸管腔211可具有比抽吸管117的前部更大的直径，以便当插管装置101处于同轴模式下时，允许汇集在第二抽吸尖端109处的抽吸流体(当同轴手持件成一角度使用时、)从第二抽吸尖端109抽出。当插管装置101处于同轴模式下时，可通过抽吸尖端109在抽吸管117中提供真空。
在一些实施方案中，抽吸尖端111可包括耦接到(例如，包覆模制到其上、拧到其上、通过粘合剂附接等、)针(例如，不锈钢插管、)的套筒107(如聚合物套筒、)。也可设想用于套筒107和针的其他材料。如图1b中所见，抽吸尖端111可包括直的针。如图1c中所见，抽吸尖端111和套筒107可以是弯曲的。在一些实施方案中，如图1c中所见，抽吸尖端111和套筒107可以在与灌注手持件部分103的具有灌注连接器113的一侧相反的方向(即，指向远离其的方向、)上弯曲，因为灌注连接器113将最有可能在外科医生抓握件的顶部上延伸并且抽吸尖端111和套筒107的相反弯曲将利用灌注手持件部分103下方的手术“自由”空间(“自由”在某种意义上是指不会被进入的灌注管路阻塞的空间、)。如图1d中所见，抽吸尖端109也可包括弯曲的针。也可设想用于抽吸尖端111和抽吸尖端109的其他针形状(例如，成角度的、直的等、)。同样，用于套筒107的其他套筒形状也是可能的(例如，成角度的、直的等、)。在一些实施方案中，用于抽吸尖端111的针可以是裸露的或由聚合物涂层包覆模制而成。在一些实施方案中，用于抽吸尖端109的针可以是裸露的或可由聚合物涂层包覆模制而成。
如图2a中所见，在一些实施方案中，到灌注手持件部分103的管道连接件可包括各种医疗路厄氏(luer、)配件。例如，管道连接件113可包括(例如，耦接到凸出型(male、)连接器209的、)如图2a所示的凹入型(female、)锁定路厄氏接口。到抽吸手持件部分105的管道连接件也可包括各种医疗路厄氏配件(例如，抽吸手持件部分105的近端137上的耦接到凹入型连接器127的凸出型连接器115、)。也可设想其他连接类型(例如，如图2b中所见，连接器113可以是凹入型连接器、)。连接器113可被配置来以角度β(例如，β角可近似在10度至25度的范围内、)接收灌注管路，以便减少灌注管路中的弯曲部(弯曲部可阻止流体流动、)并且使得抽吸手持件部分105或灌注手持件部分103更易握持在手中)。也可设想其他β角度(例如，β可近似在5度与90度之间的范围内、)。在一些实施方案中，用于抽吸的抽吸路厄氏接口115可处于抽吸手持件部分105的端部上(用于路厄氏接口115的其他位置也是可能的、)。也可设想用于灌注入口和抽吸出口的其他管道连接件(例如，摩擦配合、粘合剂等、)。
图8示出组装插管装置101的方法的流程图。流程图中提供的元件仅是说明性的。可省略各种所提供的元件，可增加另外的元件，和/或可以与下文所提供的顺序不同的顺序执行各种元件。
在801，可将抽吸尖端111耦接到抽吸管117的远端415。例如，可将抽吸尖端111拧到抽吸管117的开口中。
在803，可将止回阀201插入到抽吸管117的近端413中，直到止回阀201的O形环203抵接抽吸管117的凹进特征419。
在805，可将卡扣式保持器205插入在止回阀201后方，直到卡扣式保持器205上的一个或多个接片401扣合到抽吸管117上的接收孔403中。可使用用于卡扣式保持器205的其他附接机构。例如，可通过粘合剂、摩擦配合等将卡扣式保持器205耦接到抽吸管117。在一些实施方案中，可不使用卡扣式保持器205(例如，如图2b示出的实施方案中所见、)。
在807，可将组装好的抽吸管117插入到灌注手持件外壳体121中，直到抽吸管117上的外部O形环119抵接灌注手持件壳体121的内部上的凹进特征601。在一些实施方案中，肋状物501可与灌注手持件外壳体121的内部上的接收凹槽213对齐。
在809，可将抽吸尖端109耦接到抽吸手持件部分105的远端135。例如，可将抽吸尖端109可拧到抽吸手持件部分105上的接收螺纹中。
在811，可将抽吸手持件尖端109插入到灌注手持件部分103的近端131处的止回阀201中。如图3c至图3e所见，止回阀201可包括孔口207以允许抽吸手持件尖端109穿过止回阀201。
在813，可将抽吸手持件部分105耦接到灌注手持件部分103。例如，可将抽吸手持件部分105的端部插入到灌注手持件部分103的近端131中，并且随后进行旋拧以使抽吸手持件部分105上的接片123与灌注手持件部分103上的狭槽125接合。在一些实施方案中，灌注手持件部分103可具有接片123，并且抽吸手持件部分105可具有狭槽125。其他耦接技术也是可能的(例如，灌注手持件部分103与抽吸手持件部分105之间的摩擦配合、)。
流程图801-813的元素也可以反向进行，以便拆解插管装置101。组装/拆解可允许对插管装置101的部分或全部进行清洁和/或消毒以便可重复使用。在一些实施方案中，插管装置101的部分可重新使用，而其他部分(例如，抽吸尖端109和/或抽吸尖端111、)可在使用之间丢弃(针对每次后续使用安装新的尖端、)。在一些实施方案中，整个插管装置101可以是一次性的。在一些实施方案中，整个插管装置101可以是可重复使用的。
图9示出使用插管装置101的方法的流程图。在流程图中提供的元件仅是说明性的。可省略各种所提供的元件，可增加另外的元件，和/或可以与下文所提供的顺序不同的顺序执行各种元件。
在901，可以将同轴模式下组装好的插管装置101插入到眼睛中的第一切口1001中(例如，参见图10中的切口1001)。
在903，可通过套筒107提供灌注，并且可通过插管装置101的抽吸尖端111提供抽吸。
在905，可在眼睛中切开第二切口1003。
在907，可以将抽吸手持件部分105与灌注手持件部分103断开耦接。例如，如图1d中所见，可以旋拧抽吸手持件部分105以便将抽吸手持件部分105上的接片123与灌注手持件部分103中的狭槽125脱离接合，并且随后轴向拉动以将抽吸手持件部分105与灌注手持件部分103分开。在一些实施方案中，可将抽吸手持件部分105从灌注手持件部分103移除，而套筒107和尖端111保持在切口1001中。在一些实施方案中，可在将抽吸手持件部分105从灌注手持件部分103移除之前，将套筒107和尖端111从切口1001抽出。
在909，抽吸手持件部分105的尖端109可插入到眼睛中的第二切口1003中。
在911，当通过灌注手持件部分103穿过套筒107继续进行灌注时，可通过处于第二切口1003中的抽吸手持件部分105的尖端109提供抽吸。
在913，可将抽吸手持件尖端109从眼睛中的第二切口1003抽出。
在915，抽吸手持件尖端109可插入到灌注手持件部分103的近端131处的止回阀201中。
在917，抽吸手持件部分105可耦接到灌注手持件部分103。在一些实施方案中，可将抽吸手持件部分105耦接到灌注手持件部分103，而套筒107和尖端111保持在切口1001中。在一些实施方案中，可在将抽吸手持件部分105耦接到灌注手持件部分103之前，将套筒107和尖端111从切口1001抽出。
本领域的普通技术人员可以对所呈现的实施方案做出各种修改。通过考虑本说明书和本文所公开的本发明实践，本发明的其他实施方案对于本领域技术人员而言将是显而易见的。预期本说明书和示例应仅视为示例性的，并且本发明的真实范围和精神由随附权利要求书和其等效物来指示。
