本申请要求2021年4月13日提交的美国临时专利申请第63/174065号和2020年6月30日提交的美国临时专利申请第63/046153号的优先权,这两个专利申请中的每一个都通过引用的方式全部并入本文。
技术领域
本文中的示例可以涉及腹腔镜手术,更具体地,涉及用于在涉及使用套管针和手术器械的腹腔镜手术过程中防止或减少吹气损失的系统、装置和方法。
背景技术
肥胖是一种影响很大一部分世界人口的疾病,它会导致多种慢性疾病以及由心血管事件和癌症导致的过早死亡。特别地,美国目前的肥胖症流行情况正在恶化。美国疾病控制和预防中心(CDC)报告称,超过33%的美国人口患有肥胖,体重指数(BMI)超过30,并且另有35%-40%的美国人口超重,BMI为25-30。CDC报告称,到2018年,美国超重或肥胖人口的比例将达到75%。CDC还报告称,目前肥胖直接给美国经济造成1470亿美元的损失,预计到2020年,这一损失将接近3150亿美元。
此外,肥胖有环境、遗传和行为方面的原因,但对于大多数医学和行为干预措施来说,其都是难以解决的。为了帮助减少肥胖和/或促进减肥,减肥手术可以是一些可能超重的患者的选择。通常,对于BMI大于35的患者,减肥手术可能是一种有效的长期治疗选择。尽管美国有2000万患者符合减肥手术的条件,但每年的手术数量已稳定在20万台左右,从而消除了手术对公众健康的任何影响。
近年来,一种流行的减肥手术形式可以包括腹腔镜垂直套管胃切除术(例如,可以切除约80%的胃)。对于符合减肥手术条件的患者,腹腔镜垂直套管胃切除术可能是一种更安全、更有效的手术。事实上,它已被公认为是应当提供给大多数病态肥胖患者的手术,例如通过腹腔镜可调节胃束带和腹腔镜Roux-en-Y胃旁路手术进行。因此,该手术已被减肥外科医生采用,目前是最常用的减肥手术。
垂直套管胃切除术通常使用标准腹腔镜或“微创”设备进行。腹腔镜手术技术通常使用被称为套管针或插管的装置来执行,该装置便于将腹腔镜器械引入例如患者的腹(腹膜)腔中。这种手术通常包括用加压流体(如二氧化碳)填充或“吹入”腹腔,以在内脏和腹壁之间创造足够的操作空间。如果在腹腔镜手术过程中未正确维持吹气,那么外科医生对手术区域的观察可能会受阻。
将手术器械引入充气的腹腔而不大量损失吹入气体是理想的。这种手术器械可以例如包括缝合器、抓握器械、烧灼单元、光源、摄像头以及其他器械。套管针必须通过套管针和使用的手术器械之间的密封来保持腔内的压力,同时仍允许外科医生操作手术器械。套管针设计成在器械插入之前和器械移除之后保持密封。因此,许多套管针都提供双重密封系统。双重密封系统可以包括:顶部或近端密封件(例如唇密封件),其用于在穿过器械插入时围绕器械密封;以及设置在顶部密封件下方的鸭嘴形密封件,其用于在器械不存在时密封套管针壳体。
即使对于双重密封系统,在插入器械时,预计也会有一些吹气损失。例如,当器械包括从密封的轴延伸的末端执行器时,末端执行器可能不被密封,因而当末端执行器穿过(一个或多个)密封件时气体可以从套管针中泄漏出来。因此,在插入末端执行器与轴到达密封系统之间的时间内可能会损失吹气。因此,当前需要一种改进的套管针组件,其减少或防止器械穿过套管针插入时的吹气损失。

具体实施方式
现在将描述本发明的各种非限制性实施例,以提供对本文公开的装置、系统、方法和过程的结构、功能和使用原理的总体理解。附图中示出了这些非限制性实施例的一个或多个示例。本领域普通技术人员将理解,本文具体描述并在附图中示出的系统和方法是非限制性实施例。结合一个非限制性实施例所示出或描述的特征可以与其他非限制性实施例的特征相结合。这种修改和变化旨在包括在本发明的范围内。
在整个说明书中对“各种实施例”、“一些实施例”、“一个实施例”、“一些示例性实施例”、“一个示例性实施例”或“实施例”的引用意味着结合任何实施例所描述的特定特征、结构或特性包含在至少一个实施例中。因此,在整个说明书中各处出现的短语“在各种实施例中”、“在一些实施例中”、“在一个实施例中”、“在一些示例性实施例中”、“在一个示例性实施例中”或“在实施例中”不一定都指同一个实施例。此外,在一个或多个实施例中,能够以任何合适的方式组合特定特征、结构或特性。
套管针或腹部进入系统的尺寸在3mm至12mm(及以上)的范围内,通常分为两大类:切割套管针和扩张套管针。切割套管针包括锋利的金属或塑料刀刃,当施加压力时,该刀刃将切穿各种组织层,从而允许轻松插入腹部。扩张套管针包括在压力下分离和扩张组织的钝头。扩张套管针是非切割器械,它消除了切割系统中使用的刀刃,以最大限度地减少切割内脏器官的风险。
无论是哪种类型,套管针通常都包括三个主要部分或部件:插管、唇密封件、十字狭缝阀或中间止回阀以及闭塞器,其中闭塞器可以包括金属或塑料的削尖端头或非刀刃端头。插管基本上是在唇密封件和装置的端头之间延伸的中空管。唇密封件位于插管的顶部,旨在防止空气从腹腔逸出,同时仍允许任何必要的装置或设备穿过密封件进入插管。闭塞器(也称为锥子)位于插管的与密封件相对的底部,使得插管能够初始穿入腹部。除了唇密封件之外,套管针还可以包括位于唇密封件下方的单向进入阀,该单向进入阀允许诸如导管或摄像头之类的器械在插入该阀中时打开阀,但在器械移除时关闭。这种类型的进入阀可以称为十字狭缝阀、鸭嘴阀、瓣阀或圆顶阀。在腹腔镜手术过程中,唇密封件和十字狭缝阀协作以保持吹气压力。在医疗器械的轴已经前进经过密封件之后以及在手术空间中使用装置期间,唇密封件保持吹气压力。当套管针中没有装置存在时,十字狭缝阀维持吹气。
具有较长末端执行器的腹腔镜手术装置可能会在现有套管针中产生泄漏路径,从而导致无法充分吹气。当现有套管针中的两个密封件(例如唇密封件和十字狭缝阀)都被腹腔镜手术装置的端部穿透时,就会产生泄漏路径。该泄漏路径一直存在,直到手术装置的轴到达唇密封件,然后唇密封件围绕轴密封。对于现有的45mm和60mm缝合器装置,已经认识到了这个问题,其中这些缝合器装置具有足够长的钳口,以在到达缝合器械的轴之前穿透两个密封件。因此,一种防止或至少减少手术装置插入经过套管针的唇密封件和十字狭缝阀期间的空气泄漏的附件或装置设计将是非常有益的。
本文讨论的示例仅仅作为例示,旨在帮助解释本文描述的设备、装置、系统和方法。除非特别指定为强制性的,否则对于这些设备、装置、系统或方法中的任何一个的任何具体实现方式,在图中所示或下面讨论的任何特征或部件都不应被视为强制性的。为了便于阅读和清楚起见,某些部件或方法可能仅仅结合特定的图进行描述。任何未能具体描述部件的组合或子组合的情况都不应被理解为表明任何组合或子组合是不可能的。此外,对于所描述的任何方法,应当理解,除非上下文另有规定或要求,否则在方法的实施中执行的步骤的任何显式或隐式顺序并不意味着这些步骤必须按照所呈现的顺序来执行,而是能够以不同的顺序执行或并行地执行。
本文描述的示例性实施例可以减少将器械插入穿过套管针时的吹气损失。器械可以具有未密封部分(例如末端执行器,如缝合器)和密封部分(例如轴)。如果所插入的器械具有相对较长的末端执行器(例如,与45mm至60mm相比,250mm是较长的),那么当插入末端执行器穿过传统的套管针时,预期的吹气损失可能是显著的。器械的未密封部分(例如,末端执行器)的示例长度可以在60mm至300mm、65mm至300mm、100mm至300mm、100mm至250mm或200mm至300mm的范围内,但不限于此。器械的未密封部分的示例长度也可以大于60mm或大于100mm。此外,这种相对较长的末端执行器可以在轴到达(一个或多个)密封件之前离开套管针。大量吹气损失可能会导致可视化的损失,并且如果末端执行器已经离开套管针,那么由于缺乏可视化导致的患者与患者解剖结构的意外接触可能会对患者造成伤害。
本文描述了用于减少在将器械插入穿过套管针时的吹气损失的设备、系统和方法的示例性实施例。在一个示例性实施例中,套管针组件包括套管针和套管针护套。在一些实施例中,先将器械插入穿过套管针护套,然后将器械和套管针护套一起插入穿过套管针。与没有套管针护套的系统相比,套管针护套可以减少吹气损失。
参照图1至11,根据一个实施例,套管针组件10可以包括套管针12和闭塞器14。如图1所示,套管针12可以包括套管针插管16和套管针壳体18。套管针插管16限定具有开放的远端20和开放的近端22的内腔(见图2)。近端22延伸到套管针壳体18中并联接至套管针壳体18。套管针插管16的远端20可以是斜切的。套管针壳体18具有限定开口24的开放的近端部分。套管针壳体18包括插管帽26和套管针密封组件28。在一个实施例中,套管针密封组件28包括:第一密封件30,其靠近套管针壳体18的开口24;以及第二密封件32,其位于套管针壳体18内的第一密封件30的远侧。在一个实施例中,第一密封件30可以是唇密封件,而第二密封件32可以是十字狭缝阀或鸭嘴阀,例如双鸭嘴阀。应当理解,套管针密封组件可以包括一个密封件或多于两个密封件,并且具有多种配置。应当认识到,套管针密封组件28与闭塞器14或延伸穿过套管针插管16的另一手术器械协作,以密封地接合其外表面,从而阻止流体通过套管针12。
参照图3和图4,闭塞器14在套管针12内可滑动且可移除地延伸。闭塞器14能够可移除地插入套管针壳体18的开口24中,穿过套管针密封组件28,穿过套管针插管16,并且从套管针插管16的远端20伸出。闭塞器手柄34设置在闭塞器14的近端,并且锋尖或锋利的刀刃36形成在闭塞器14的远端。当插入套管针12中时,闭塞器手柄34抵接套管针壳体18,并且闭塞器14的刀刃36延伸出套管针插管16的远端20。套管针12和闭塞器14一起用于通过将闭塞器14的刀刃36抵靠软组织放置并压靠闭塞器手柄34而在软组织中刺孔。在刀刃36划开组织的内表面之后,可以移除闭塞器14,并且由套管针12形成穿过组织的开放通道。
现在参照图5至图7,在一个实施例中,套管针组件10可以包括适配器38。将理解的是,套管针12的尺寸通常可以设定为适配于特定尺寸范围内的器械或工具。当显著小于该尺寸的器械插入套管针12中时,套管针密封组件28将不能提供适当的密封。如图5所示,可以将适配器38插入套管针壳体18的开口24中,以允许较小的器械与套管针12一起使用,同时提供适当的密封。适配器38包括从适配器壳体42延伸的适配器插管40。适配器插管40限定具有开放的远端44和开放的近端46的内腔。近端46延伸到适配器壳体42中并与适配器壳体42联接。适配器壳体42具有限定开口48的开放的近端部分。如图6所示,当插入套管针12中时,适配器壳体42抵接套管针壳体18,并且适配器插管40的远端44延伸到套管针插管16中并与套管针插管16流体连接。适配器38的开口48小于套管针壳体18的开口24。适配器38还可以包括适配器密封组件50。在一个实施例中,适配器密封组件50可以包括:第一密封件,其靠近适配器壳体42的开口48;以及第二密封件,其位于适配器壳体42内的第一密封件的远侧。在一个实施例中,第一密封件可以是唇密封件,而第二密封件可以是十字狭缝阀或鸭嘴阀,例如双鸭嘴阀。应当理解,适配器密封组件可以包括一个密封件或多于两个密封件,并且具有多种配置。应当认识到,适配器密封组件50与延伸穿过适配器插管40的手术器械协作,以密封地接合其外表面,从而阻止流体通过套管针12和适配器38。
如图8至图11所示,在一个实施例中,套管针组件10可以包括套管针护套52。套管针护套52在套管针12内可滑动且可移除地延伸。套管针护套52能够可移除地插入套管针壳体18的开口24中,穿过套管针密封组件28,并且穿过套管针插管16。套管针护套52可以包括护套插管54和壳体组件56。护套插管54限定具有开放的远端58和开放的近端60的内腔。近端60延伸到壳体组件56中并与壳体组件56联接。壳体组件56具有限定开口62的开放的近端部分。在一些实施例中,护套插管54是由塑料(例如HDPE)制成的薄壁管,其具有足够的刚性,从而不会在使用过程中发生折叠(collapse),并且足够薄,从而不会显著增加套管针12的所需内径。在另一实施例中,护套插管54可以是柔性的。护套插管54的壁厚可以在例如0.005英寸至0.01英寸的范围内,例如0.008英寸。在各种实施例中,护套插管54可以是透明的、亚透明的(semi-transparent)、半透明的(translucent)或不透明的。尽管套管针护套52被示出为是与套管针12分离的部件,但在其他实施例中,套管针12和套管针护套52可以共同模制或共同形成。
进一步参照图9和图11,在一个实施例中,壳体组件56可以包括密封板64、护套毂66、护套密封件68和护套帽70。密封板64可以联接至护套插管54的近端60。密封板64限定开口并且包括从远端裙部74延伸的近端唇部72。裙部74的尺寸可以设定成延伸到护套插管54的开放的近端60中。护套毂66联接至护套插管54的近端60的外部。捕获在护套毂66中的护套插管54的近端60可以向外扩口,以提供机械锁定特征,而不减小护套插管54的有效内径。密封板64可以相应地扩口。密封板64捕获护套插管54以在使用期间承受拉伸载荷。
仍然参照图9和图11,在一个实施例中,护套毂66可以包括外壁76,外壁76限定穿过外壁76的开口。例如,外壁可以是凹形的,并用作抓握部。护套毂66还可以包括从外壁76朝向护套毂66的远端延伸的内裙部78。因此,护套毂66的直径可以变化。例如,在外壁76处的护套毂66的近端开口的直径可以大于在内裙部78处的护套毂66的远端开口的直径。将认识到,护套毂66的构造可以变化。例如,护套毂66可以具有单个裙壁。护套密封件68和护套帽70的尺寸设定成配合在护套毂66的开口中。护套密封件68和护套帽70可以被护套毂66容纳。护套密封件68包括限定开口的大致圆形外壁80。在示例性构造中,护套密封件68是唇密封件,并且包括从外壁80延伸到开口中的唇部82。护套密封件68可以构造成相对于插入其中的器械的轴的阻力(drag)比套管针密封组件28和套管针护套52之间的阻力要小。在一个实施例中,当器械被穿过护套密封件68插入时器械上的阻力可以小于当器械被穿过护套密封件68移除时器械上的阻力。护套帽70还包括限定开口的大致圆形外壁84。在一些实施例中,护套帽70可以在护套插管54的近端60、护套密封件68和包含在护套毂66中的密封板64上提供轴向预载荷,以提供气密密封,从而防止使用中的空气泄漏。在各种实施例中,可以使用超声波焊接工艺、胶水或卡扣配合将护套帽70保持在位。
在一个实施例中,套管针护套52可以包括无密封件的壳体组件56。护套插管54的内径与器械的外径之间的差值可以非常小。例如,护套插管54的内径与器械的外径之间的差值可以在0.001英寸至0.01英寸、0.001英寸至0.005英寸、0.005英寸至0.01英寸、或0.002英寸至0.005英寸的范围内。
图10和图11示出了定位在套管针12中的套管针护套52。如图所示,护套插管54可以延伸超过套管针插管16的远端20。在另一个实施例中,护套插管54的尺寸设定为不延伸超过套管针插管16的远端20的斜切端。换言之,在这种构造中,由于斜切,护套插管54的一部分可以不被套管针插管覆盖,但是套管针插管16的斜切端延伸经过护套插管54的远端58。当套管针护套52定位在套管针12中时,套管针密封组件28与套管针护套52协作以密封地接合套管针护套52的外表面。类似地,当器械定位在套管针护套52中时,套管针护套52的壳体组件56与器械协作以密封地接合器械的外表面。因此,在一种构造中,套管针12、套管针护套52和插入穿过套管针护套52的器械协作以阻止流体通过套管针12。
在各种实施例中,套管针护套52可以包括锁定特征(例如,在护套毂66上),以将器械轴的近端(例如,缝合器的手柄)锁定至套管针护套52。示例性构造包括快速连接接头、锁定在轴上的径向压缩弹簧、护套上的卡合在器械轴护罩中的叉齿(prong)/凸缘上的螺纹、器械轴护罩上的被管滑过的挤出成型部(extrusion)、手柄护罩上的被管滑入的底切部(undercut)、外管上的被护套上的近端毂卡入的凹槽,或者它们的组合。
在各种实施例中,套管针护套可以构造成与现有套管针一起使用(例如,以改装方式),或与设计为与套管针护套一起使用的套管针一起使用。
在使用中,外科医生或其他用户可以将套管针12和闭塞器14插入患者的组织中。在闭塞器14的刀刃36划开组织之后,可以将闭塞器14从套管针12移除。如果使用相对较小的器械,则可以插入适配器38。否则,可以将待使用的器械插入套管针护套52中。将器械的远端插入套管针壳体18的开口24中。当器械的远端延伸穿过第二密封件32时,通过第二密封件32和器械的未密封远端部分(例如,器械的末端执行器)形成泄漏路径。如果没有套管针护套52,只要器械的未密封部分延伸穿过第一密封件30和第二密封件32(即,在器械的密封部分到达第一密封件30之前),就会存在泄漏路径。在具有套管针护套的情况下,泄漏路径仅在从器械的远端部分穿过第二密封件32到护套插管54到达第一密封件30时才存在。因此,套管针护套52减少了当器械插入套管针12时可能损失吹气的时间量。对于具有较长未密封部分的器械(例如,较长的缝合器),该时间的减少会更大。对于一些器械,在末端执行器离开套管针插管16的远端20之前,套管针护套52密封套管针12。这减少或消除了当末端执行器伸出套管针12时由于吹气损失而导致可视化损失的可能性。为了从套管针12移除器械,将套管针护套52与器械一起移除。如果先移除器械并且失去与套管针护套52的壳体组件56之间的密封,那么只要护套插管54延伸穿过第二密封件32,就可能发生吹气损失。
如前所述,具有较长末端执行器的腹腔镜手术装置可以在现有套管针中产生泄漏路径,从而导致无法充分吹气。当现有套管针中的两个密封件(即,唇密封件和十字狭缝阀)都被腹腔镜手术装置的端部穿透时,就会产生泄漏路径。在手术装置的轴到达唇密封件之前,该泄漏路径将一直存在。对于具有足够长的钳口以在到达缝合器的轴之前穿透两个密封件的现有45mm和60mm缝合装置,已经认识到该问题。
一些缝合装置(例如Standard Bariatrics公司的TITAN SGS)的钳口大约为250mm长,因此带来了两个与吹气泄漏有关的额外问题。首先,插入TITAN SGS缝合器的250mm长的钳口所需的时间是现有45mm和60mm装置所需时间的4至5.5倍,这允许更多的空气在到达插入的缝合器械的轴部分之前从吹气体积泄漏。如果在插入缝合器械的过程中损失了大量空气,则可能会失去可视化,从而导致在无法可视化的期间因与患者解剖结构的意外接触而导致潜在的患者受伤。其次,TITAN SGS装置的250mm钳口的长度足够大,足以在到达缝合器械的轴并停止吹入空气泄漏之前从腹内腔中的套管针中退出。这一点非常重要,因为如果外科医生更快地插入缝合器械以将空气泄漏量降至最低,那么缝合器械可能会以不受控制的方式从腹内空间中的套管针中退出,从而导致因意外接触患者解剖结构而造成潜在的患者受伤。
图12提供了包括插管102、唇部110和插管帽112的示例性套管针100的透视图。插管102包括锥形上部104和管状下部106,其中上部104的内径大于下部106的内径,并且下部106终止于有角度的端头108。如前所述,诸如图12所示的套管针通常包括密封件和阀,密封件和阀在腹腔镜手术过程中协作以保持吹气压力。密封件通常为唇密封件,而阀为十字狭缝阀。在医疗器械的轴已经前进经过密封件之后以及在手术空间中使用器械期间,唇密封件保持吹气压力。当套管针中没有器械时,十字狭缝阀保持吹气。图13提供了套管针100的截面图,其中在插管帽112的下方可见唇密封件120,并且十字狭缝阀130设置在插管102的锥形上部104内。下面描述的各种实现方式防止了在器械插入经过唇密封件120和十字狭缝阀130的过程中的空气泄漏。尽管图中示出了十字狭缝阀130,但是在设置于插管的远端部分内的另一个阀用于在医疗器械存在于插管中时防止空气泄漏的实现方式中,十字狭缝阀130可能是不必要的。
图14和图15示出了远端球囊的实现方式,其用于在十字狭缝阀打开且器械的轴未到达唇密封件时,使器械插入套管针的过程中的空气泄漏最小化。图14提供了示例性套管针200的透视图,其包括插管202、唇部210和插管帽212。插管202包括锥形上部204和管状下部206,其中上部204的内径大于下部206的内径,并且下部206终止于有角度的端头208。图15提供了套管针200的截面图,其中在插管帽212的下方可见唇密封件220,并且近端十字狭缝阀230设置在插管202的锥形上部204内。使远端球囊242充气和放气的球囊泵管240穿过插管帽212进入套管针200,并与插管202的中心轴线平行地向下延伸到插管202的管状下部206中。在该实现方式中,唇密封件220与现有套管针中的唇密封件相同,并且设计成在插入套管针200中的器械的轴上形成密封。近端十字狭缝阀230也与现有套管针中的十字狭缝阀相同,并且设计成在关闭时防止空气泄漏。插管202也与现有套管针中的插管相同,并且设计为刚性管,以允许器械穿过该管插入,从而进入腹腔。插管帽212也与现有套管针中的插管帽相同,并且设计成将唇密封件200和近端十字狭缝阀230保持在插管202内。插管帽212也可以与其他工具配合,例如闭塞器和5mm适配器。球囊泵管240允许空气被泵入和泵出远端球囊242,其中远端球囊242是甜甜圈形的,并且位于套管针200内,朝向套管针的远端。器械被推过球囊242的中心,并且当器械完全插入时,球囊242被放气。替代的实现方式包括用自膨胀记忆泡沫等效物代替球囊,这不需要球囊泵来充气。
图16示出了缝合器的远端密封件的实现方式,其为TITAN SGS外科缝合器附件,设计成在十字狭缝阀打开且器械的轴尚未到达套管针的唇密封件时,使缝合器械插入期间的空气泄漏最小化。如图16所示,末端执行器300在其远端包括销,该销用于将钝头302销接到末端执行器的端部。末端执行器的唇密封件304与钝头302的外径配合,并填入钝头302的外径与套管针插管的内径之间的空气间隙。与末端执行器的唇密封件304结合的钝头302允许在发生空气泄漏之前将末端执行器300的远端一直插入套管针的远端,从而最小化空气泄漏开始时与缝合器械的轴到达套管针的唇密封件之间的时间。在一些实现方式中,该附件能够从末端执行器300移除。
图17和图18示出了远端密封件的实现方式,其中当十字狭缝阀打开且器械的轴尚未到达唇密封件时,该远端密封件使器械插入套管针期间的空气泄漏最小化。图17提供了示例性套管针400的透视图,其包括插管402、唇部410和插管帽412。插管402包括锥形上部404和管状下部406,其中上部404的内径大于下部406的内径,并且下部406终止于端头408。图18提供了套管针400的截面图,其中在插管帽412的下方可见唇密封件420,并且近端十字狭缝阀430设置在插管402的锥形上部404内。在多种实现方式中,阀430都不存在于插管402中,因为它不是必需的。远端阀440设置在管状下部406的远端部分内。在该实现方式中,唇密封件420与现有套管针中的唇密封件相同,并且设计成在插入套管针400中的器械的轴上形成密封。近端十字狭缝阀430也与现有套管针中的十字狭缝阀相同,并且设计成在关闭时防止空气泄漏。插管402也与现有套管针中的插管相同,并且被设计为刚性管,以允许器械穿过该管插入,从而进入腹腔。插管帽412也与现有套管针中的插管帽相同,并且设计成将唇密封件420和近端十字狭缝阀430保持在插管402内。插管帽412也可以与其他工具配合,例如闭塞器和5mm适配器。远端阀440在关闭时防止空气泄漏。通过将阀440朝向套管针400的远端放置,在打开阀并允许空气泄漏之前,可以将器械更深地插入套管针插管402中,从而最小化空气泄漏开始时与器械的轴到达唇密封件之间的时间。远端阀440可以是十字狭缝阀、活板瓣、扩张阀等。一种替代实现方式不包括近端十字狭缝阀430,而另一种替代实现方式将远端阀440完全定位在套管针400的远端开口处。
图19A至19C和图20示出了一种伸缩套筒的实现方式,其包括可与现有套管针技术结合使用的附件,以在十字狭缝阀打开并且缝合器械的轴尚未到达唇密封件时消除缝合器械插入套管针的过程中的空气泄漏。如图19A至19C所示,缝合器械150包括手柄152、轴154和末端执行器156。如图20所示,毂500包括保持环502、唇密封件504和护套或套筒506。在图19A中,毂500尚未放置在末端执行器156上。在图19B中,毂500已经放置在末端执行器156上,并且套筒506被示出为沿着末端执行器156的长度部分地延伸。在图19C中,套筒506已经沿着末端执行器156完全延伸并且已经到达缝合器械150的轴154。毂500充当内部部件的壳体,并且还为用户提供外部抓握表面,以使套筒506滑动到缝合器械150上并使套筒506容易地沿着轴154的轴线平移。唇密封件504与现有套管针中使用的唇密封件类似,并且设计成在插入套管针中的器械的轴上形成密封。该部件的另一个重要方面是其在缝合器械的轴上的阻力。与套管针的唇密封件和套筒之间的阻力相比,唇密封件504设计成相对于器械的轴具有更小的阻力。保持环502容纳并保持唇密封件504、有角度的帽和套筒506的扩口端。保持环502可以使用超声波焊接、粘合剂、卡扣配合或任何其他合适的附接方式附接至毂500。保持环502在包含于其中的部件上提供足够的轴向预载荷,以形成不允许使用期间的空气泄漏的气密密封。套筒506通常由可膨胀薄壁橡胶、低密度聚乙烯(LDPE)或类似材料制成,其位于毂500内并包括两个或更多个部分。缝合器械在毂中的插入类似于望远镜那样延伸套筒506的每个部分,使得缝合钳口的整个长度都被密封。
伸缩套筒的替代实现方式包括毂500上的锁定特征,其中当缝合器械150完全插入套筒506中时,该锁定特征将毂锁定在手柄152的近端上。该锁定特征可以包括快速连接接头、锁定在轴154上的径向压缩弹簧、毂或套筒506上的卡合在手柄152的护罩中的叉齿/凸缘上的螺纹、手柄护罩上的被管滑过的挤出成型部、手柄护罩上的被管滑入的底切部和/或外管上的被套筒506上的毂500卡入的凹槽。其他变型包括毂500上的锁定特征,该锁定特征锁定在套管针的近端上。
图21示出了一种刷毛阀的实现方式,其包括可与现有套管针技术结合使用的附件,以在十字狭缝阀打开并且缝合器械的轴尚未到达唇密封件时消除缝合器械插入套管针的过程中的空气泄漏。毂600充当内部部件的壳体,并且还为用户提供外部抓握表面,以使套筒滑动到缝合器械上并使套筒(例如套筒506)容易地沿着缝合器械的轴的轴线平移。唇密封件604与现有套管针中使用的唇密封件类似,并且设计成在插入套管针中的器械的轴上形成密封。该部件的另一个重要方面是其在缝合器械的轴上的阻力。与套管针的唇密封件和套筒之间的阻力相比,唇密封件604设计成相对于器械的轴具有更小的阻力。保持环602容纳并保持唇密封件604、有角度的帽和套筒的扩口端。保持环602可以使用超声波焊接、粘合剂、卡扣配合或任何其他合适的附接方式附接至毂600。保持环602在包含于其中的部件上提供足够的轴向预载荷,以形成不允许使用期间的空气泄漏的气密密封。刷毛608以圆形图案排列在毂600的内侧。当缝合器械插入毂600中时,刷毛608填入缝合器械的末端执行器部件的上钳口和下钳口之间的任何间隙,这降低了当缝合器械穿过套管针插入时任何吹气泄漏的速率。
刷毛阀的替代实现方式包括毂600上的锁定特征,其中当缝合器械完全插入套筒中时,该锁定特征将毂锁定在缝合器械的手柄的近端上。该锁定特征可以包括快速连接接头、锁定在器械的轴上的径向压缩弹簧、套筒上的卡合在手柄护罩中的叉齿/凸缘上的螺纹、手柄护罩上的被管滑过的挤出成型部、手柄护罩上的被管滑入的底切部和/或外管上的被套筒上的毂600卡入的凹槽。其他变型包括毂560上的锁定特征,该锁定特征锁定在套管针的近端上。
图22A至22C和图23示出了一种卷缩(rolled)护套的实现方式,其包括可与现有套管针技术结合使用的附件,以在十字狭缝阀打开并且缝合器械的轴尚未到达唇密封件时消除缝合器械插入套管针的过程中的空气泄漏。如图22A至22C所示,缝合器械150包括手柄152、轴154和末端执行器156。如图23所示,毂700包括保持环702、唇密封件704和完全卷缩的护套706。在图22A中,毂700尚未放置在末端执行器156上。在图19B中,毂700已经放置在末端执行器156上,并且护套706被示出为沿着末端执行器156的长度部分地展开。在图19C中,护套706已经沿着末端执行器156完全展开,并且已经到达缝合器械150的轴154。毂700充当内部部件的壳体,并且还为用户提供外部抓握表面,以使护套706滑动到缝合器械150上并使护套706容易地沿着轴154的轴线平移。唇密封件704与现有套管针中使用的唇密封件类似,并且设计成在插入套管针中的器械的轴上形成密封。该部件的另一个重要方面是其在缝合器械的轴上的阻力。与套管针的唇密封件和护套之间的阻力相比,唇密封件704设计成相对于器械的轴具有更小的阻力。保持环702容纳并保持唇密封件704、有角度的帽和护套706的扩口端。保持环702可以使用超声波焊接、粘合剂、卡扣配合或任何其他合适的附接方式附接至毂700。保持环702在包含于其中的部件上提供足够的轴向预载荷,以形成不允许使用期间的空气泄漏的气密密封。护套706通常由可膨胀薄壁橡胶、低密度聚乙烯(LDPE)或类似材料制成,并且位于毂700内。当器械被插入时,将缝合器械150插入到毂700中将使得护套706被展开,因而当器械完全插入时,末端执行器156的钳口的整个长度都被密封。形成在护套706的远端中的孔708因为围绕末端执行器膨胀而允许器械被推过孔708。
卷缩护套的替代实现方式包括毂700上的锁定特征,其中当缝合器械150完全插入护套706中时,该锁定特征将毂锁定在手柄152的近端上。该锁定特征可以包括快速连接接头、锁定在轴154上的径向压缩弹簧、护套706上的卡合在手柄152的护罩中的叉齿/凸缘上的螺纹、手柄护罩上的被管滑过的挤出成型部、手柄护罩上的被管滑入的底切部和/或外管上的被护套706上的毂700卡入的凹槽。其他变型包括毂700上的锁定特征,该锁定特征锁定在套管针的近端上。
图24至26示出了一种可折叠套筒组件的实现方式,其包括可与现有套管针技术结合使用的附件,以在十字狭缝阀打开并且缝合器械的轴尚未到达唇密封件时消除缝合器械插入套管针的过程中的空气泄漏。如图24最佳所示,可折叠套筒组件800包括容纳唇密封件804的近端毂802、套筒806、套筒配合结构808、容纳唇密封件的套管针配合毂810以及附接至套管针配合毂810的护套814。近端毂802充当内部部件的壳体,并且还为用户提供外部抓握表面,以使套筒806滑动到缝合器械上并使套筒806容易地沿着缝合器械的轴的轴线平移。唇密封件804与现有套管针中使用的唇密封件类似,并且设计成在插入套管针中的器械的轴上形成密封。该部件的另一个重要方面是其在缝合器械的轴上的阻力。套筒806是由低密度聚乙烯(LDPE)或类似材料制成的薄壁袋,其足够薄,从而在被压缩时发生折叠,而在拉力下被拉动时发生膨胀但不裂开。套管针配合毂810充当安装内部部件的壳体,并且还在可折叠套筒组件800滑入套管针中时为用户提供外部抓握表面。套管针配合毂810在插入套管针中时保持与套管针齐平。套筒配合结构808与套筒806协作以形成围绕套管针配合毂810和近端毂802的气密密封。护套814是由高密度聚乙烯(HDPE)或类似材料制成的薄壁管,其足够刚性,从而在使用期间不会发生折叠,同时又足够薄,从而不会显著增加套管针的内径。在一个示例性实现方式中,护套的壁厚约为0.008英寸厚。与套管针配合毂810中的唇密封件804和缝合器械之间的阻力相比,护套814设计成相对于套管针唇密封件具有更大的阻力。
可折叠套筒组件的替代实现方式包括近端毂802上的锁定特征,其中当缝合器械完全插入套筒806中时,该锁定特征将毂锁定在缝合器械的手柄的近端上。该锁定特征可以包括快速连接接头、锁定在器械的轴上的径向压缩弹簧、套筒806上的卡合在手柄护罩中的叉齿/凸缘上的螺纹、手柄护罩上的被管滑过的挤出成型部、手柄护罩上的被管滑入的底切部和/或外管上的被套筒806上的近端毂802卡入的凹槽。
