技术领域
本公开涉及手术装置,更具体地,涉及与手术装置一起使用以有利于治疗组织的通电附件。
背景技术
内窥镜手术器械通常包括壳体和端部执行器组件,壳体具有从其延伸的轴,端部执行器组件布置在轴的远端处。内窥镜手术钳例如包括具有爪部件的端部执行器组件,并且依赖于爪部件之间的机械作用来抓持、夹持和/或收缩组织。电手术钳利用机械夹持作用和电能,通过加热组织以凝固和/或烧灼组织,来实现止血。某些手术过程不仅要求简单地烧灼组织,而且依赖于夹持压力、精确的电手术能量控制和间隙距离(即,在围绕组织闭合时在相对的爪部件之间的距离)的独特组合来“密封”组织。在一些手术过程(例如,需要穿过一层或多层组织进行解剖或者以其它方式治疗该组织的过程)中,为了到达要密封或以其它方式治疗的下层组织,使用双极和单极器械两者可能是有利的。

参考图1A,根据本公开提供的通电手术附件总体由附图标记200示出。通电手术附件200总体包括外鞘210、朝向外鞘210的近端定位的连接器附件215、以及穿过外鞘210或在外鞘210内延伸的通电杆部件220。如下所述,通电手术附件200构造成用于围绕手术器械的轴(例如手术钳10的轴12(图3))定位,并且可相对于该轴手动移动以利于治疗组织。
外鞘210限定了大致管状的细长构造,并且如上所述,构造成用于围绕内窥镜器械的轴(例如手术钳10的轴12(图3))定位。外鞘210的内表面和外表面可以由电绝缘材料形成或涂覆有电绝缘材料。如下所述,外鞘210限定了适当的长度以能够围绕内窥镜器械的轴在缩回位置和部署位置之间进行滑动运动,并且使得外鞘210的远端能够延伸到内部手术部位,同时外鞘210的近端保持在外部布置,以使得使用者能够操作外鞘210。更具体地,外鞘210构造成由使用者抓持并且沿着内窥镜器械的轴在缩回位置(图4A)和部署位置(图7A)之间手动纵向滑动。外鞘210可进一步围绕内窥镜器械的轴手动旋转。外鞘210另外包括布置在其中的一个或多个O形环218(图4A和4B),其重要性在下面描述。
连接器附件215朝向通电手术附件200的近端定位,并且从外鞘210分叉。连接器附件215构造成利于一个或多个插头213、214与其连接,以用于能够向通电杆部件220选择性地供应能量,如下所述。
另外参考图2,通电杆部件220从外鞘210向远侧延伸,最终限定了导电远侧末端224。通电杆部件220(更具体地其远侧末端224)用作通电手术附件200的有效电极。通电杆部件220的远侧末端224可以是钩形(如所示),或者可以限定任何其它的适当构造,例如直线形、球形、圆形、角形、针形等等。通电杆部件220在远侧末端224近侧的露出部分可涂覆有电绝缘材料。通电杆部件220的近侧部分可构造成穿过外鞘210或在外鞘210内延伸以最终联接到连接器附件215,或者可终止于外鞘210内或外鞘210内的更远侧,并且经由一个或多个导线207(图4A和4B)联接到连接器附件215。能量可(例如经由手动启动开关216(见图1B)或其它适当致动器的启动)从连接器附件215通过通电杆部件220供应到远侧末端224以治疗组织。供应到组织的能量可以是单极电能、超声能、热能、光能、氩气能、或者任何其它适当的能量。通电杆部件220可以定位在外鞘210的一侧上(如为了例示而在图1A、2、5、6B和7B中提供的那样),定位在外鞘210的另一侧上(如为了例示而在图4A、4B、6A和7A中提供的那样),或者可定位在顶部、底部或其间的任何适当位置。
通电杆部件220可牢固固定在外鞘210中。可选地,通电杆部件部署致动器223可布置在外鞘210上并且经由任何适当机构(未示出)联接到通电杆部件220。通电杆部件部署致动器223朝向外鞘210的近端定位,并且可沿着外鞘210选择性滑动以从外鞘210的远端或进一步超出外鞘210的远端部署通电杆部件220,并且将通电杆部件220缩回至外鞘210的远端中或更接近外鞘210的远端。
现在参考图1B,提供了构造成用于与连接器附件215可释放地联接的连接器组件205。连接器组件205包括经由缆线211连接到第一连接器213的手动启动开关216、以及经由缆线212连接到第二连接器214的插头217。第一连接器213和第二连接器214分别构造成与连接器附件215可释放地联接,以用于能够从能源(未示出,与插头217连接)选择性地(例如在手动启动开关216启动时)将能量通过线212和导线207(图4A和4B)供应到通电杆部件220。
手动启动开关216构造成接通和断开流向连接器附件215(从而流向导线207(图4A和4B)并且最终流向通电杆部件220)的能量流。手动启动开关216可构造成接合内窥镜手术器械的壳体,例如钳10的壳体20(见图4A),或者可构造成经由粘性剂、卡扣连接器或其它适当接合结构或机构来接合内窥镜手术器械的轴(例如钳10的轴12(见图4B)),或者可选地构造成由使用者保持或附接。也能想到用于联接到连接器附件215的其它连接器组件,例如与脚踏开关和其他开关组件关联的连接器组件。
参考图3,构造成与通电手术附件200一起使用的手术器械的一个实施例标记为手术钳10。手术钳10总体包括壳体20、手柄组件30、触发器组件60、旋转组件70和端部执行器组件100。手术钳10还包括轴12,轴12具有与端部执行器组件100机械接合的远端和延伸到壳体20的近端。手术钳10还包括电手术缆线2,电手术缆线2将钳10连接到发电机(未示出)或其它适当能源,不过钳10可以可选地构造为电池供电的手持器械。缆线2包括延伸穿过其的线(未示出),线具有足够的长度以穿过轴12延伸,从而例如在启动开关4启动时向端部执行器组件100的爪部件110、120各自的导电表面112、122的至少一个提供电能。旋转组件70能够沿两个方向旋转,以相对于壳体20旋转端部执行器组件100。壳体20容纳钳10的内部工作构件。
手柄组件30包括可动手柄40,可动手柄40最终连接到布置在壳体20内的驱动组件(未示出),它们机械地协作以使得爪部件110、120在隔开位置和接近位置之间运动,从而在爪部件110、120各自的表面112、122之间抓持组织。更具体地,可动手柄40能够从与爪部件110、120的隔开位置对应的初始位置致动到与爪部件110、120的接近位置对应的下压位置。在一些实施例中,提供布置在轴12内并包括刀的刀组件180(未示出),刀能够例如经由触发器组件60的启动而在爪部件110、120之间选择性延伸,从而切割被抓持在表面112、122之间的组织。
现在参考图4A、4B和5,示出的通电手术附件200围绕手术钳10的轴12布置在缩回位置,使得通电杆部件220未超出端部执行器组件100向远侧延伸,并且使得端部执行器组件100超出外鞘210露出以能够利用其抓持和治疗组织。如图4A所示,连接器组件205联接到连接器附件215,手动启动开关216位于轴12上。如图4B所示,连接器组件205联接到连接器附件215,手动启动开关216位于壳体20上。
如上所述,外鞘210包括一个或多个O形环218,O形环218联接到外鞘210的内表面并在由外鞘210限定的内腔中延伸。O形环218朝向外鞘210的近端定位,并且限定了内径比钳10(或者构造成用于插入穿过O形环218的其它手术器械)的轴12的外径小的孔径,使得多个O形环218在围绕轴12定位通电手术附件200时被压缩,以在外鞘210的内腔中产生不透流体的密封,从而防止吹入气体在其间逸出。O形环可插入沟槽、狭槽中或配合地附接在外鞘210内。多个O形环218也在外鞘210的内表面与轴12的外表面之间产生摩擦,从而在外鞘210和轴12之间产生运动偏压,使得在缺少适当推压以克服该偏压的情况下,通电手术附件200相对于钳10通过摩擦保持在适当位置。可以理解到,用于通电手术附件200的O形环218的尺寸根据一起使用的手术器械的轴的尺寸和/或诸如不透流体的密封需求或运动偏压需求之类的其它因素而改变。
参考图4A和6A-7B,为了部署通电手术附件200,利用足以克服O形环218的偏压的推压,外鞘210围绕轴12从缩回位置(图4A)向远侧通过部分部署位置(图6A和6B)滑动到完全部署位置(图7A和7B),在完全部署位置通电杆部件220延伸超出端部执行器组件100的远端,外鞘210围绕端部执行器组件100布置。此外,在通电手术附件200部署之前、期间或之后,外鞘210可相对于轴12旋转以将通电杆部件220旋转到期望定向。之后,能量可例如经由手动启动开关216的启动而施加到通电杆部件220,以利用通电杆部件220的远侧末端224治疗组织。通电手术附件200的缩回按照与部署相反的方式进行。
根据以上描述并参考各个附图,本领域技术人员将理解,可以对本公开进行某些修改而不脱离本公开的范围。虽然已经在图中示出了本公开的几个实施例,但本公开不旨在限制于此,本公开的范围旨在和领域所允许的一样宽,并且说明书旨在同样理解。因此,以上描述不应理解为限制,而是仅仅理解为对具体实施例的例示。本领域技术人员能够在所附权利要求的范围和精神内想到其它的修改。
