Description

一种内镜钳道内的药液喷洒装置
交叉引用
本发明要求在中国专利局提交的、申请号为201910038717.8、发明名称为“一种内镜钳道内的药液喷洒装置”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本发明涉及医疗器械技术领域，尤其涉及一种内镜钳道内的药液喷洒装置。
背景技术
在内镜手术中，由于人体自然腔道中各种体液、粘液的存在，对内镜视野产生了影响，提高了手术难度。为了清晰内镜手术视野，准确地检查人体内部病灶组织，精确地进行内镜手术操作，需要喷洒装置等配合内镜使用的处置器具。该器具因操作方便、价格低廉等特点，被广泛应用于内镜临床及手术中。
由于患者腔道内病变组织的临床特征是纷繁复杂的，常规的喷洒装置通过内镜钳道进入体腔后，喷洒药液时可能造成污染并遮挡内镜镜头，影响了喷洒或冲洗效果，给内镜手术造成不利影响而影响手术进度，增加了内镜临床手术的操作难度。
因此，需要提供一种内镜钳道内的药液喷洒装置，该喷洒装置设有保护装置，在喷洒过程中可以保护内镜镜头不受喷洒液体的影响。
发明内容
本发明实施例的目的在于提供一种内镜钳道内的药液喷洒装置，利用形状记忆合金作为保护装置，对内管的喷洒头进行保护，保证不影响内镜镜头。
为实现上述发明目的，第一方面，本发明实施例提供了一种内镜钳道内的药液喷洒装置，包括手柄、外管、中管、内管和保护装置，所述外管的远端与手柄固定连接，所述内管套设在中管内，所述中管套设在外管内，所述手柄内设有手柄推进器，所述内管的远端和中管的远端均与手柄推进器固 定连接，手柄推进器可以同时将中管和内管推出；所述保护装置套设在内管与外管之间，所述保护装置的近端与中管的远端接触，中管推出时，可以将保护装置推出；所述内管的近端端头设有喷洒头。内管需保证通畅且不漏液，喷洒头需保证能够成功喷洒液体。
优选地，所述内管上设有内管凸起，所述保护装置与内管凸起固定连接。保护装置和内管凸起可以使用胶粘方式固定。
优选地，所述保护装置的材质为形状记忆合金。保护装置一开始在外管内，在离开外管的管口后可以逐渐张开。
优选地，所述保护装置为镍钛记忆合金丝编织结构，所述镍钛记忆合金丝的直径不超过0.5mm。
优选地，所述保护装置的内表面或外表面覆有保护膜。保护膜的作用是保护药液不会溅射到内镜镜头上。
优选地，所述保护膜为硅胶柔性高分子材料，所述保护膜的厚度不超过0.3mm。硅胶具有韧性和透明的特性，保证保护膜与保护装置同时变形，且不会遮挡视线影响内镜手术。
优选地，所述保护装置的近端展开呈伞状且保护装置展开最大直径不小于10mm。
优选地，所述内管的近端靠近喷洒头的内壁上设有内螺纹。内螺纹可形成螺旋路径，药液在螺旋路径内旋转通过，与喷洒头形成剪切效果，产生喷雾效果。
优选地，所述外管的外径不超过2.6mm。所述外管的外表面光滑，且外径小于内镜钳道最小内径2.8mm，为了保证喷洒装置能够自由的进入和离开内镜钳道。
与现有技术相比，本发明实施例具有以下有益效果：
本发明由于采用了以上技术方案，喷洒装置操作简单，只需操作手柄即可将内管、中管和保护装置同时推出，保护装置以及保护膜罩设在内管的喷洒头外，保护药液不会污染内镜镜头，对患者腔体进行喷洒作业，且使用后内管、中管和保护装置可同时退回至外管，不影响内镜手术。
上述说明仅为本发明技术方案的概述，为了能够更清楚地了解本发明的技术手段并可依据说明书的内容予以实施，同时为了使本发明的上述和其他目的、技术特征以及优点更加易懂，以下列举一个或多个优选实施例，并配合附图详细说明如下。

具体实施方式
下面结合附图，对本发明的具体实施方式进行详细描述，但应当理解本发明的保护范围并不受具体实施方式的限制。
除非另有其他明确表示，否则在整个说明书和权利要求书中，术语“包括”或其变换如“包含”或“包括有”等等将被理解为包括所陈述的元件或组成部分，而并未排除其他元件或其他组成部分。
在本文中，为了描述的方便，可以使用空间相对术语，诸如“下面”、“下方”、“下”、“上面”、“上方”、“上”等，来描述一个元件或特征与另一元件或特征在附图中的关系。应理解的是，空间相对术语旨在包含除了在图中所绘的方向之外物件在使用或操作中的不同方向。例如，如果在图中的物件被翻转，则被描述为在其他元件或特征“下方”或“下”的元件将取向在所述元件或特征的“上方”。因此，示范性术语“下方”可以包含下方和上方两个方向。物件也可以有其他取向(旋转90度或其他取向)且应对本文使用的空间相对术语作出相应的解释。
如图1至图4所示，一种内镜钳道内的药液喷洒装置，包括手柄5、外 管1、中管2、内管3和保护装置4，所述外管1的远端与手柄5固定连接，所述外管1的外径不超过2.6mm。所述外管1的外表面光滑，且外径小于内镜钳道最小内径2.8mm，为了保证喷洒装置能够自由的进入和离开内镜钳道。
所述内管3套设在中管2内，所述中管2套设在外管1内，所述手柄5内设有手柄推进器51，所述内管3的远端和中管2的远端均与手柄推进器51固定连接，手柄推进器51可以同时将中管2和内管3推出。
所述保护装置4套设在内管3与外管1之间，所述保护装置4的近端与中管2的远端接触，中管2推出时，可以将保护装置4推出；所述内管3的近端端头设有喷洒头32。内管3需保证通畅且不漏液，喷洒头32需保证能够成功喷洒液体。所述内管3的近端靠近喷洒头32的内壁上设有内螺纹33。内螺纹33可形成螺旋路径，药液在螺旋路径内旋转通过，与喷洒头32形成剪切效果，产生喷雾效果。
所述内管3上设有内管凸起31，所述保护装置4与内管凸起31固定连接。保护装置4和内管凸起31可以使用胶粘方式固定。
所述保护装置4的材质为形状记忆合金。保护装置4需有一定硬度且具有形状记忆功能。保护装置4一开始在外管1内，在离开外管1的管口后可以逐渐张开。所述保护装置4的近端展开呈伞状且保护装置4展开最大直径不小于10mm。
所述保护装置4优选镍钛记忆合金丝编织结构，所述镍钛记忆合金丝的直径不超过0.5mm。
所述保护装置4的内表面或外表面覆有保护膜。保护膜的作用是保护药液不会溅射到内镜镜头上。所述保护膜为柔性高分子材料，优选硅胶，所述保护膜的厚度不超过0.3mm。硅胶具有韧性和透明的特性，保证保护膜与保护装置4同时变形，且不会遮挡视线影响内镜手术。
使用时，如图2所示，保护装置4打开前，保护装置4、内管3和中管2都在外管1内。当需要喷洒装置作业时，如图4所示，操作手柄5上的手柄推进器51，将中管2和内管3同时推出，由于保护装置4与中管2接触且保护装置4与内管3上的内管凸起31固定连接，所以保护装置4会同时被推出。当保护装置4离开外管1的管口时，保护装置4的近端逐渐张开呈伞状，此时内管3的喷洒头32也同时离开外管1的管口，内管3内的药液经内螺纹33可形成螺旋路径，药液在旋转路径内旋转通过，与喷洒头32 形成剪切效果，产生喷雾效果，对患者腔体进行喷洒作业。当喷洒作业完成后，再次操作手柄5的手柄推进器51将内管3和中管2同时退回，由于保护装置4与内管3上的内管凸起31固定连接，保护装置4可随内管3一起退回，以此将保护装置4和内管3一起退回至外管1中。
前述对本发明的具体示例性实施方案的描述是为了说明和例证的目的。这些描述并非想将本发明限定为所公开的精确形式，并且很显然，根据上述教导，可以进行很多改变和变化。对示例性实施例进行选择和描述的目的在于解释本发明的特定原理及其实际应用，从而使得本领域的技术人员能够实现并利用本发明的各种不同的示例性实施方案以及各种不同的选择和改变。针对上述示例性实施方案所做的任何简单修改、等同变化与修饰，都应落入本发明的保护范围。
工业实用性
