Description
技术领域
本申请涉及支气管镜检查法,并且更特别地涉及用于连接、紧固、和密封支气管镜的适配器。
背景技术
正在被通气的患者的气道可能被气管内导管紧固。气管内导管通常由橡胶或塑料制成,且通过自然上气道(即,嘴或鼻、咽、和喉)插入,或通过到气管的手术途径(即,气管造口术)插入。气管内导管可配有围绕其气管端的可充气套囊,所述可充气套囊密封气管,且因此允许正压通气以及保护气道不被外来物质沾污。通常,导管的在患者远侧的端部经由管件系统联接到通气器,或经由在导管出口处的止回阀通向周围空气。
在肺医学领域中的通常介入程序是支气管镜检查法,在所述支气管镜检查法中,支气管镜通过患者的鼻或嘴插入气道中。支气管镜的结构一般包括长、薄、柔性的导管,所述导管典型地包含三个元件:照明组件,其用于经由连接到外光源的光学纤维照明在支气管镜末端远侧的区域;成像组件,其用于传递回来自支气管镜的远侧末端的视频图像;以及腔体或工作通道,仪器可通过所述腔体或工作通道插入,包括但不限于诊断仪器(例如,活组织检查工具)和治疗仪器(例如,激光,低温,射频,或微波组织处理探头)。支气管镜的远侧末端是可操纵的。旋转放置在支气管镜的手柄处的杆会致动沿一个或多个方向偏转末端的操纵机构。
支气管镜检查法由也称为支气管镜检查者的胸腔科医师执行,并且按惯例在诸如肺癌、气道狭窄、和肺气肿的疾病的诊断和治疗中使用。支气管镜检查法典型地由至少两位人员执行:支气管镜检查者和至少一个助理,通常为护士。在典型程序期间,支气管镜检查者以一只手握持支气管镜手柄且以另一只手握持支气管镜导管。支气管镜检查者通过旋转偏转杆且通过推拉导管来操纵在肺内侧的支气管镜的远侧末端。一旦末端被带到目标,仪器就能够插入工作通道中以进行诊断或治疗程序。
在仪器的插入和操作期间,支气管镜的远侧末端应该在目标处保持稳定。需要两只手将支气管镜紧固就位,并且需要一只或两只更多的手插入和致动仪器。通常,支气管镜检查者释放支气管镜以插入和致动仪器。需要两个人进行程序一般是更昂贵的,并且错误的潜在性增加。因此,期望修改程序,以使得如果可能的话所述程序可以通过一只或两只手进行。
附加地,因为与支气管镜一起使用的所有仪器必然长且纤细,仪器在未被支撑时不会保持形状。因此,难于或不可能以一只手快速地将仪器插入支气管镜中。虽然这个问题能够通过以一只手握持鞘端且以另一手握持仪器而容易地解决,但是这将再次在进行程序期间需要附加的空闲的手。
因此,需要与支气管镜一起使用的这样一种适配器,所述适配器将有助于单个执业医师操作支气管镜和关联工具。也将有利的是,给支气管镜的工作通道的连接端口提供一种适配器,所述适配器在程序期间进行密封和仪器锁定功能而无需替换附件。
发明内容
在本申请的一方面,支气管镜锁定机构包括夹持部件和螺母。夹持部件包括螺纹部分和夹持表面。夹持表面限定配置成与气管导管连通的可压缩通道。螺母包括内螺纹表面和外表面。内螺纹表面配置成与夹持部件的螺纹部分协作。在可压缩通道的第一位置,可压缩通道限定第一直径,而在可压缩通道的第二位置,可压缩通道限定小于第一直径的第二直径。当螺母在螺纹部分上前进时,螺母与夹持部件干涉,以使得可压缩通道从第一位置朝向第二位置移动。夹持部件可包括两个或更多个片。夹持部件可包括具有夹持表面的悬臂式部件。
在一些实施方式中,螺母可在螺纹部分上向近侧前进,以将可压缩通道从第一位置转变到第二位置。在其他实施方式中,螺母在螺纹部分上向远侧前进,以将可压缩通道从第一位置转变到第二位置。
在某些实施方式中,螺母的外表面配置成增强触感。螺母的外表面可包括倒圆突起、花瓣形突起、星形突起、翼部、或滚花,以增强触感。
在本申请的一些方面,气管导管适配器组件包括支气管镜、具有近侧部分和远侧部分的细长导管、和锁定机构。锁定机构在细长导管的近侧定位且限定纵向轴线。锁定机构包括夹持部件和螺母。夹持部件限定与细长导管的近侧部分轴向对齐的可压缩通道。螺母包括内螺纹表面和外表面。内螺纹表面配置成与夹持部件的螺纹部分协作。可压缩通道具有限定第一直径的第一位置和限定第二直径的第二位置。当可压缩通道处于第一位置时,支气管镜在可压缩通道内自由滑动,而当可压缩通道处于第二位置时,支气管镜纵向固定在可压缩通道内。当螺母在螺纹部分上前进时,螺母与夹持部件干涉,以使得可压缩通道从第一位置朝向第二位置移动。锁定机构的夹持表面可与支气管镜形成密封。
在一些实施方式中,锁定机构围绕细长导管的近侧部分定位。在某些实施方式中,细长导管具有接近于细长导管的近端定位的近侧凸缘。
在一些实施方式中,气管导管组件还包括肘部、第一连接器、和第二连接器。肘部包括侧壁开口且在锁定机构远侧定位。第二连接器在肘部远侧定位。肘部和第二连接器与锁定机构轴向对齐。第二连接器定位在锁定机构和细长导管之间。第一连接器包括细长本体。细长本体的端部联接到肘部的侧壁开口。肘部可限定第一通路,而第二连接器可限定与第一通路流体连通的第二通路。第一连接器的细长本体可限定通过肘部的侧壁开口与第一和第二通路流体连通的第一腔体。第一连接器的细长本体还可限定邻近于第一腔体的第二腔体。第二腔体可通过肘部的侧壁开口与第一和第二通路流体连通。第一腔体可配置成允许流体流入第一和第二通路中且阻止流体从第一和第二通路流出。第二腔体配置成允许流体从第一和第二通路流出且阻止流体流入第一和第二通路中。
在本申请的一些方面,用于紧固支气管镜的方法包括:将支气管镜插入锁定机构的可压缩通道中,且通过使螺母在锁定机构的螺纹部分上前进而将支气管镜紧固在锁定机构中。螺母压缩夹持表面以减小可压缩通道的直径。在实施方式中,所述方法还包括在支气管镜紧固在锁定机构中之后通过支气管镜插入仪器。
而且,在一致的程度上,在此描述的任何方面可与在此描述的任何或所有其他方面结合使用。

具体实施方式
现在参考附图详细描述本申请的实施方式,在附图中,相同的附图标记在多幅图中的每幅代表相同或对应的元件。在此使用时,术语"临床医生"指代支气管镜检查者、医生、护士、或任何其他护理提供者且可包括辅助人员。在整个说明书中,术语"近侧"将指代装置或其构件的最靠近临床医生的部分,而术语"远侧"将指代装置或其构件的最远离临床医生的部分。
现在参照图1,依据本申请提供的气管导管组件10结合有气管导管或细长导管12以及支气管镜锁定机构20。细长导管12具有近侧部分14和远侧部分16,限定从中穿过的腔体18。近侧部分14联接到连接器15。支气管镜锁定机构20以密封关系布置在连接器15的外表面上方。支气管镜锁定机构20相对于连接器15固定。支气管镜锁定机构20限定纵向轴线"A-A"。
另外参照图2,锁定机构20包括夹持部件22和螺母30。锁定机构20能够接近于近侧部分14的近端定位。夹持部件22包括螺纹部分24、夹持表面26、以及可压缩通道28。夹持表面26围绕纵向轴线"A-A"定位,以限定可压缩通道28。在实施方式中,夹持表面26包括成角度的引导部26a,所述引导部配置成在支气管镜300插入腔体18中时将支气管镜300的远端推入通道28中。
螺母30包括螺纹内表面32和外表面34。螺母30的螺纹内表面32配置成接合螺纹本体24的螺纹。螺母30的外表面34能够成形为增强临床医生的手和/或手指的触感和/或接合性。如图1所示,外表面34包括围绕纵向轴线"A-A"径向定位的六个倒圆突起34a。外表面34能够是滚花的、花瓣形的、星形的、包括翼部、或具有任何其他形状或特征,从而增强临床医生的触感或容易接合性,以围绕螺纹本体24旋转螺母30。
现在参照图2和3,螺母30的螺纹内表面32成锥形,以使得当螺母30在螺纹部分24上前进时螺母30的螺纹内表面32与螺纹部分24干涉,以向内压缩夹持表面26。随着夹持表面26向内压缩,通道28的直径减小。通道28具有在螺母30与螺纹部分24干涉之前的未压缩直径或第一直径θ1和在螺母30处于在螺纹部分24上的前进位置且与螺纹部分24干涉之后的压缩直径或第二直径θ2。能够理解的是,随着螺母30在螺纹部分24上前进,通道28的直径从第一直径θ1转变到第二直径θ2,第二直径θ2小于第一直径θ1。例如,通道28能够配置成接收外径5.7mm的支气管镜300。在这个示例中,通道28的第一直径θ1大于5.7mm,从而允许支气管镜300自由地穿过通道28,并且通道28的第二直径θ2小于5.7mm,使得夹持表面26接合支气管镜300,以将支气管镜300锁定在固定纵向位置。夹持表面26能够由柔性材料构成,所述柔性材料在其接触支气管镜300时变形或压缩。在一些实施方式中,支气管镜300能够在被夹持表面26接合时旋转。在某些实施方式中,支气管镜300在被夹持表面26接合时可旋转且纵向地固定。在特定实施方式中,夹持表面26与支气管镜300的接合随着螺母30在螺纹部分24上前进而可调整,以首先相对于锁定机构20纵向固定支气管镜300、而后可旋转地固定支气管镜300。
依据另一实施方式,图2A中示出的夹持部件22的锥形可压缩部分24a而非螺纹部分24匹配反向锥形的滑动件30a。滑动件30a在锥形可压缩部分24a上前进(向近侧移动)以压缩夹持部件22而将支气管镜300固定在锁定机构20内,并且缩回(向远侧移动)以释放夹持部件22在支气管镜300上的压缩。在一些实施方式中,锥形滑动件30a可与夹持部件22的锥形可压缩部分24a一体形成。
替换性地,如图2B所示,锁定机构20可包括正交于纵向轴线定向的两个或更多个弹簧加载板25。每个板25包括当板25处于非夹持位置时定位在通道28上的中央通路27。第一板25且尤其中央通路27被偏压到沿横向于纵向轴线的第一方向偏移的夹持位置,而第二板25且尤其中央通路27被偏压到沿横向于纵向轴线的第二方向偏移的夹持位置,第二方向与第一方向相反。为了插入支气管镜300,第一和第二板25沿与它们相对于通道28偏移到非夹持位置的方向相反的方向移动,使得每个板25的中央通路27与通道28对齐。当支气管镜穿过板的中央通路时,板25被释放且被弹簧作用(例如,弹簧25a)偏压,以使得每个板25朝向其夹持位置移动,以将支气管镜300固定在通道28内。
参照图4,依据本申请的另一气管导管组件110设置成结合有细长导管12和锁定机构120。
附加地参照图5和6,夹持部件122包括联接到螺纹部分124的悬臂式部件127。悬臂式部件127包括夹持表面126,所述夹持表面配置成在夹持表面126接合定位在通道28内的支气管镜300时偏转。夹持表面126可由柔软的可压缩材料制成,配置成接合支气管镜300的表面。悬臂式部件127的偏转维持夹持表面126基本平行于纵向轴线"A-A",从而允许夹持表面126接合支气管镜300的长度增加。
当通道28处于限定第一直径θ1的第一位置时,锁定机构120的螺母130在夹持组件120的螺纹部分124的近侧定位。在一些实施方式中,当螺母130接合螺纹部分124的近端时,通道28处于第一位置。类似于上述螺母30,当螺母130在螺纹部分124上前进时,通道28被压缩而实现第二位置,所述第二位置限定比第一直径θ1小的第二直径θ2。
参照图7和8,依据本申请的另一气管导管适配器组件210设置成结合有锁定机构220、肘部240、气道连接器250、和细长导管12。细长导管12可替换性地包括母连接器(未示出),以允许连接到气道装置的公连接器(未示出)。例如,母连接器可以是依据ISO5361的15mm连接器,以允许连接到15mm公连接器。
锁定机构220的夹持部件由围绕纵向轴线"A-A"径向隔开的两个或更多个片225形成,其中每个片225包括夹持表面226和螺纹部分224的一部分。随着螺母230在片225上前进,每个片225之间的空间从第一直径θ1减小到小于第一直径θ1的第二直径θ2。
肘部240包括开口近端241、开口远端246、侧壁开口245、和第一通路248。锁定机构220联接到肘部240的近端241。侧壁开口245基本正交于纵向轴线"A-A"且配置成接收气道连接器250。附加地或替换性地,肘部240可以是基本"Y"形,以使得在锁定机构220和气道连接器250之间限定锐角。第一通路248与通道28连通。
具有臂243的盖242能够接近于肘部240的近端联接。臂243远离纵向轴线"A-A"延伸且配置成折叠以允许盖242密封通道28。在实施方式中,锁定机构220包括在片225的螺纹部分224的远侧定位的基部221,盖242具有延伸的本体243,盖242配置成在锁定机构220的螺纹部分224上延伸,以与基部221形成密封。
气道连接器250配置成通过细长导管12提供通气。气道连接器250包括细长本体252、第一联接件254,且限定第一腔体256。第一腔体256布置在细长本体252内。在实施方式中,气道连接器250还能够包括布置在细长本体252内的第二腔体257。如图8所示,第二腔体257邻近于第一腔体256,其中隔膜252a定位在第一和第二腔体256、257之间。在一些实施方式中,第二腔体257与第一腔体256共轴地布置。第一联接件254能够是配置成联接呼吸回路或通气器的15mm连接器。每个腔体256、257能够包括配置成阻止流体沿一个方向流动的方向阀(未示出)。例如,第一腔体256能够包括配置成允许流体从第一联接件254流动到第一通路248且阻止流体从第一通路248流动到第一联接件254的阀(未示出),并且第二腔体257能够包括配置成允许流体从第一通路248流动到第一联接件254且阻止流体从第一联接件254流动到第一通路248的阀(未示出)。
连接器15限定腔体18的一部分。连接器15的近端布置在肘部240的远端246上,其中腔体18与第一通路248和通道228流体连通。在实施方式中,腔体18具有大于第一通路248的直径。在一些实施方式中,第一通路248或腔体18形成与第一和第二腔体256、257流体连通的空间。在一些实施方式中,第一和第二腔体256、257延伸穿过侧壁开口245和连接器15。连接器15的远端流体连通地联接到细长导管12的近侧部分14。
将理解的是,气管导管适配器组件210的各个构件可相对于彼此旋转,以减小构件不经意解除联接的可能性,且维持构件之间的气密连接。例如,锁定机构220可相对于肘部240旋转,并且气道连接器250可相对于肘部240旋转。元件的旋转可最小化构件之间的旋转力或扭转力。
根据本申请的方面,用于紧固支气管镜的方法包括:将支气管镜插入锁定机构的通道中且通过使螺母在锁定机构的螺纹部分上前进而紧固支气管镜。以上气管适配器组件10、110、和210中的任何一个能够与所述方法结合使用。所述方法可包括在支气管镜紧固在锁定机构中之后通过支气管镜插入仪器。所述仪器可包括但不限于诊断仪器(例如,活组织检查工具)和治疗仪器(例如,激光、低温、射频、或微波组织处理探头)。
虽然本申请的数个实施方式已经在附图中示出,但是并非旨在将本申请限制于此,因为旨在使本申请的范围与本领域允许且说明书被理解地那样广泛。也可以设想以上实施方式的任何结合且在所附权利要求的范围内。因此,以上说明书不应该被解释为限制性的、而仅仅是特定实施方式的举例。本领域技术人员将设想到在所附权利要求范围和精神内的其他修改。
