Abstract
一种内窥镜轴(2)的可以去掉的罩,包括用弹性材料制成的套(4),其具有低摩擦的外表面,以便内窥镜轴向前移动的摩擦阻力小于内窥镜轴向后移动的摩擦阻力。
Description
本发明涉及内窥镜以及内窥镜的盖子或管套。
从六十年代末期柔性内窥镜装置己在医学上应用;然而,该装置的基本设计从七十年代初以来没有显著的变化。由于能够直接看到内部器官,准确进行病变定位并且可以取出样本用于显微镜分析,因此它的主要用途是用于诊断和治疗胃肠道失调。由于能够通过内窥镜将外科工具导入,内窥镜在治疗病人方面也变得很重要。小的肿瘤能够被取出、实施激光治疗、进行注射,小的区域能够被扩展并且可以取出异物。早期的内窥镜用光导纤维以便进行观察,但是,较先进的内窥镜通过电视成象原理,使用电子集成电路片将图象显示在电视屏幕上。
肠胃病学中使用的内窥镜主要有四种类型:上消化道内窥镜,经嘴用于检查食道、胃和十二指肠;十二指肠镜内窥镜,用于检查胰脏两侧的工作;结肠窥镜,用于检查大肠(结肠镜检查术);以及肠窥镜,用于检查小肠(肠窥镜检查术)。
为了实施结肠镜检查,病人首先经受强烈泻药疗法清除大肠内的排泄物。给他们服用轻微镇静剂和止痛剂后,将柔性内窥镜装置通过肛门导入并且向上通过大肠。检查的极限通常为盲肠,盲肠是大肠的最上面部分,但是,熟练的操作者能够将装置导入到小肠的下部。
实施结肠镜检查技术上困难,并且需要长时间的学习。即使通过训练以后,一些操作者也比其他操作者更熟练,并且能够比其他操作者更快、更安全、更有效地实施操作。该操作困难的原因是,因为结肠形状和结构是变化的。它包括一系列的弯曲部分通过血管和连接组织连接在腹腔内的固定位置,血管和连接组织向该器官提供营养,而结肠的其他部分在腹腔内能够相对自由移动。当柔性的但相当坚硬的装置插入到肠子内时,有出现打卷的倾向。当出现这种情况时,熟练的操作者能够减少卷的大小,并且使装置与肠子协调。通过扭曲、推、拉和倾斜装置的尖部使其在肠子内前进,直到到达盲肠。较不熟练的内窥镜操作者感到这种操作困难,并且在腹腔内形成的卷较大。当出现这种情况时,不但前进困难,而且给病人造成痛苦,并且肠系膜有被拉过度的危险。到达盲肠的时间长度从10分钟到一个小时之间不等,有时根本不可能到达盲肠。
结肠镜检查术是检查大肠最有效的技术。不但提倡将其用于结肠症和结肠疾病病人的诊疗检查,其还用于癌症的鉴定。(在英国结肠癌是最常见的第二致命癌症)。结肠镜检查术特别适合于在癌症恶化之前通过结肠内窥镜很容易将小息肉取出,因为癌症开始时通常为小息肉。如果结肠镜检查术简单易行,其应用将能极大地减少癌症的危险。然而,作为鉴定技术,该技术费用昂贵,容易给病人造成不适,限制了它的广泛应用。如果能够在短时间内准确到达盲肠并且不引起病人不适,该技术将得到更广泛的应用。
最近估计,仅在英国每年有250,000人接受结肠镜检查。如果更容易接受并且费用便宜的话,将远远不止这些。主要的费用为人工费用和普通费用,而不是重要仪器的费用,因此如果在单位时间内能够检查更多的病人费用将大大降低。
肠窥镜检查术不常应用的一个主要原因是其操作困难。小肠是胃肠道最长的部分,并且内窥镜只能首先通过食道、胃和十二指肠才能到达小肠;然后才能进入小肠。小肠本身是旋绕的,具有许多扭曲和回转,将内窥镜送进穿过小肠是很困难的、也是很痛苦的,并且只能检查小肠的上部。这方面的原因是,当使用“推”肠窥镜时,肠窥镜出现的结阻止其推进,结果造成卷曲并且出现打卷。肠窥镜检查术的另一个方法是使用“拉”肠窥镜,其比较薄,并且经过鼻子随后使其在自身动力下运动(象食物一样)穿过小肠。其能够被取出,并且当其到达后能够观察小肠。遗憾的是,其易于迅速四处滑动、扭曲、回转,因此整个小肠仍然不容易观察。此外,由于其太薄不可能通过它实施处理手段。
本发明的优选实施例的一个目的是,提供一种带外表面的内窥镜,其允许消化道内窥镜检查,包括结肠镜检查和肠窥镜检查能够更快、更安全地完成,并且不适感更少,就象流行的设备一样。
按照较宽的方面,本发明属于一个用于内窥镜轴的罩,包括一个套,该套至少在向前移动的方向具有低摩擦表面,以有助于内窥镜轴的使用。
本发明还在于,内窥镜包括一个柔性轴,近端与观察装置连接,末端为自由端,其中至少在轴长度的一部分上,轴表面设计为:轴向前移动通过人体通道(在使用时轴插入)提供的摩擦阻力比轴向后移动通过人体通道提供摩擦阻力小。
该内窥镜能够提供低摩擦表面,其形式可以为特殊的表面覆盖层,最好为低摩擦聚合物。一种形式为湿涂的液体硅氧烷涂层,随后干燥形成一个很薄的低摩擦覆盖层。而且,低摩擦表面可以通过覆盖套提供,使其表面成型,以保证在向前与向后通过人体通道,例如,肠子(轴插入其中)时摩擦力不同。套至少从末端覆盖内窥镜轴的长度的一部分,并且最好覆盖其全部或大部分长度。套最好为薄壁,例如低于0.5mm,比如0.1mm到0.3mm并且弹性足以包紧柔性轴。套不必紧包在内窥镜轴上,有时套用于轴时较松包裹较好。套和轴之间的摩擦力能够防止它们纵向相对移动,不需要套包紧内窥镜轴。此外,特别是,如果套用摩擦系数相当高的材料制成和/或在轴的周围紧配合时,希望在套的内表面提供涂层以减少摩擦,从而有助于将套覆盖到内窥镜轴上,以及以后从轴上去掉套。如果套通过在芯轴或模型上成型制造,内部涂层能够通过套随后从芯轴上取下并且反转,涂到套材料上,这种技术被用于加工其他物品,例如,医用手套。
就套的外部摩擦性质来说,应当依靠套材料本身的低摩擦特点,或者依靠涂到套外表面上的上述类型的低摩擦涂层。通常,套能够喷涂在芯轴上,合适的弹性材料包括天然橡胶、聚氯丁烯、和聚氨基甲酸乙酯。套的外表面能够通过处理改进,特别是减少表面摩擦力。通过使用亲水的水凝胶聚合物能够得到非常润滑的表面。如果需要的话,可以将润滑剂涂到套的外表面。向前和后退方向的摩擦阻力不同,在使用时向前和后退分别与插入和拉出的方向对应。由于前进方向比后退方向的摩擦阻力较小,当向后拉的力作用到内窥镜轴上时,内窥镜能够有选择地拉动肠子,这样相应地,通过使肠子与内窥镜协调有助于减少肠子的打卷。摩擦力的不同能够通过表面突出物或使柔性轴长度的一部分或全部具有某种结构而得到。结构能够通过外部涂层形成,但是,最方便的是,套上形成类似鱼鳞的突出物或浅棱形。此外,可以使用向后的猪鬃,例如,沿套间隔排列成环状。在另一种方法中,可以使用推进装置,例如以脉冲方式蠕动或蛇行或喷射空气或注射水。
应当知道,尽管内窥镜轴向后移动提供较大的阻力,但是仍然能够向后拉内窥镜而不伤害肠子,并且,在结肠镜检查情况下,特别是直肠黏膜通常紧紧抓紧内窥镜的外部。在后退的情况下,套能够有助于使套和内窥镜轴分开取出,为此目的,套应当设置一个纵向薄弱线,可以沿该线将套撕开,以便有助于轴和套分开。
为了使本发明能够更清楚地理解,下面通过例子参考附图描述本发明的实施例,其中:
图1概括地示出了按照本发明的一个内窥镜;
图2示出了图1的内窥镜的一部分的大比例图;
图3是一个与图2相似的视图,示出了套的一个改进形式;
图4为穿过另一种套的侧壁的纵向剖面图;并且
图5为敷贴器的示意图,用于将套套到内窥镜轴上。
参考图1,内窥镜以传统结构为基础,并且包括一个窥视孔部分1和一个插入轴2。插入轴2的末端3包括透镜、通道和导光装置。当然,正如本领域众所周知的一样,内窥镜能够被代替以适合于电视成象。套4加在插入轴2上,并且沿其整个长度或一部分延伸。
套可以为一次性的或进行消毒的,如果是一次性的,应以无菌包装购买。它是非常坚固的产品,以便在使用时不断开或磨损,并且其用电绝缘材料制成,而且十分柔软不干扰内窥镜本身的使用。其适合于在潮湿肮脏的环境下使用,并且具有合适的尺寸,能够使用大范围的加工工具。因此,套应当用低摩擦系数的无毒材料制成,并且应当柔软、坚固、或者一次性使用或者消毒使用。该套本身能够与内窥镜连接、不导电并且防水(不湿润)。套用弹性好的材料制成,以便套能够固定在内窥镜的轴上,当使用内窥镜时,套不沿轴滑动。
该套“使用者欢迎”,因此其能够容易并且快速地安装在仪器上,并且能够很简单地去掉。这样操作者在使用时能够完成仪器的处理。其应当具有“临床”外观。
参考图2,套4的外表面有突起物形成“鱼鳞”表面5。这样形成的表面在前进/插入方向的摩擦系数比在后退/拉出的方向摩擦系数低。图3示出了图2的另一种替换装置,其中安装了细的毛发或鬃6,以产生上面提到的不同的摩擦系数。长度、硬度、厚度、沿长度方向厚度的变化、柔韧性以及鳞或鬃的端部的特征可以按照需要变化。它们可以为连续的或间隔开的。
图4示出了另一种套的结构,其特别适合于通过模制工艺在芯轴上加工套,例如,通过浸渍成型工艺。套4具有沿套连续的棱状轮廓形成的突出物8,因此,得到了锯齿轮廓。锯齿状突出物可以为环状并且沿套的四周连续延伸。或者它们可以为不连续的并间隔开。棱与轴以小角度倾斜,例如5°到10°,并且倾斜面可以为任何合适的长度,例如5mm到10mm。棱状突出物的后部或尾随面最好与套轴大体垂直。
图5示出了在内窥镜轴上使用的内窥镜罩。罩的套协调折叠在环状支架10内,支架的一端有一个开口,套4的前端从此处伸出。支架的外壁延伸形成引导颈11,以有助于将套导到内窥镜轴2上。该实施例的套在其前端安装有一个环12,该环能够与内窥镜轴的末端3啮合。支架10越过轴2的端部将环与末端3啮合,支架沿轴移动,轴穿过支架运动,与其相隔一个缝隙;因此,套从支架内逐渐拉开,并且覆盖在轴2上,由于套材料本身的弹性而包在轴上。
应当明白,上面的实施例只是通过例子进行了描述,只要不偏离本发明的范围可以有许多变例。套可以设计成能够可充气式,以便推进装置只能在充气(或排气)状态下操作,使得撤退能够更安全地完成。
