Description
技术领域
本发明属于激光医疗器械,通过结合光刀、激光溶脂、生命科学与光纤成像技术,使脂肪从血管壁上脱落并分解为小分子从而解决血管堵塞的装置。
背景技术
我国心血管病的发病持续增加,血管疾病患病率是所有疾病中最高的,而且心血管的患病人数占我国所有患病人数的百分之八十七,现有治疗手段还停留在药物控制和血管搭桥支架层面。现有手段存在诸多弊端,从安全性、经济性与普及性上面存在很多问题,急需新的技术对目前所存在的问题进行优化解决,提高对此类疾病治疗的安全性及可靠性。
光镊以一种温和的、非机械接触的方式完成夹持和操纵物体,捕获力是施加在整个微粒上,非机械捕获那样集中在很小的面积上,不会对捕获的生物微粒造成机械损伤和污染。光镊与高空间分辨率的技术相结合,使之具备精细的结构分辨能力和动态操控与功能研究的能力。光的无形性和穿透性,光镊可以在保持细胞自然生活环境的情况下对其进行捕获与操纵。光镊的所有机械部件离捕获对象的距离都远大于捕获对象的尺度(1000倍),是遥控操作。
光刀是用激光代替手术刀进行手术的医疗装置。激光有单一方向性,能量密度高,可利用其热效应、光效应和电磁效应等切割身体组织。用激光刀进行手术,切口平滑,出血少,不易感染。
光刀与光镊技术是一种作用在微米尺度的高能量低损伤方式,在使用激光对不同细胞和物质进行实验的过程中,得到了适当波长与能量的激光对脂类与血浆的作用,通过将这些技术融合,对血管栓塞的治疗有了新突破。
激光对组织可产生热、光、化学效应及生物刺激作用,激光溶脂时激光治疗仪释放激光能量,通过激光的热效应选择性融化脂肪细胞的细胞膜,从而造成脂肪破裂液化,脂肪细胞数量减少。目前,激光溶脂技术广泛的应用于瘦身、美容等领域,血管堵塞正是由于脂肪的堆积,同样的,激光溶脂技术也可应用于血管堵塞领域。
单光纤成像技术采用单根多模光纤进行成像,光纤既是成像器件又是传像器件,无需增加扫描器件和成像透镜便可将光纤一端视场范围内的场景一次性传输到另一端,,因此又称为宽场光纤成像技术。该技术可减小成像光纤探头的直径,实现超细内窥成像。
发明内容
本发明将激光技术、生命科学技术相结合,通过组合光纤从血管内作用于脂类堵塞物,作用精准,局部能量可调可控,并且使用脂肪酶分解脂肪效率极高且不会有后遗症,大大减小了药物治疗的不确定性以及解决了搭桥、支架手术的后遗症问题。本发明中提到的金属网并不会留在患者体内,待脂肪清楚清除之后将金属网取出,并将伤口进行缝合。本发明的目的是通过以下技术方案实现的。
一种通过激光对血管内脂肪堵塞物进行清除的装置,
包括光刀部件和血管疏通部件;
其中所述光刀部件包括激光器12、反射镜15、双色分束镜16,由激光器12发射激光,经由反射镜15进入双色分束镜16分束后分别进入目镜11和物镜13,通过物镜13后的激光聚焦为光刀,通过目镜11的激光经由CCD采集和计算机处理实现对图像信息的采集;
其中所述血管疏通部件包括:激光器1、组合光纤2、计算机7、显微操作仪3、金属网6;其中组合光纤2为成像光纤和溶脂光纤结合的组合光纤,由显微操作仪3实现对组合光纤的控制,金属网6为涂覆有脂肪酶的金属网,用于清除血管内多余的脂肪。
优选,其中,组合光纤2的尾纤熔拉成锥,通过多维调节仪夹持控制尾纤,以方便尾纤探入血管中合适的位置。
优选,其中金属网6可自动伸缩,金属网6的轮廓紧贴血管壁或与血管内壁保持很小的距离。
优选,其中,金属网6包括金属柄,闲置时金属网6收缩于金属柄内,探入血管后金属网6探出,且与血管轴向垂直。
优选,其中金属网6间隙的大小可调,通过调节金属网6的间隙,用于清除血管内多余的脂肪。
优选,其中金属网6间隙的大小调节是通过增加或减少金属网的数量的实现。
本发明的优点在于:
本发明通过包括光刀部件和血管疏通部件的血管内脂肪堵塞物清除装置,使用光纤尾纤进行溶脂,使脂肪从血管壁上脱落下来,顺着血液流动,当脂肪流动至涂覆有脂肪酶的金属网时将被脂肪酶分解成脂肪酸和甘油,从而解决血管堵塞问题。
附图说明
通过阅读下文优选实施方式的详细描述,各种其他的优点和益处对于本领域普通技术人员将变得清楚明了。附图仅用于示出优选实施方式的目的,而并不认为是对本发明的限制。而且在整个附图中,用相同的参考符号表示相同的部件。在附图中:

图2为一种通过激光对血管内脂肪堵塞物进行清除的装置的血管疏通部件;
图3为一种通过激光对血管内脂肪堵塞物进行清除的装置的血管疏通部件中金属网的截面图。
具体实施方式
下文将参照附图更充分地描述本发明的实施例,本发明的优选实施例在附图中示出。然而,本发明可以以不同的方式实施,而不应被解释为仅限于此处所述的实施例。
这里所用的术语仅仅是为了描述特定实施例,并非要限制本发明。如此处所用的,除非上下文另有明确表述,否则单数形式“一”和“该”均同时旨在包括复数形式。还应当理解,术语“包括”、“包括”、“包括”和/或“包括”,当在此处使用时,指定了所述特征、整体、步骤、操作、元件和/或组件的存在,但并不排除一个或多个其他的特征、整体、步骤、操作、元件、组件和/或其组合的存在或添加。
如图1所示,为一种通过激光对血管内脂肪堵塞物进行清除的装置的光刀部件;其中所述光刀部件包括激光器12、45°反射镜15、双色分束镜16,由激光器12发射激光,经由45°反射镜15进入双色分束镜16分束后分别进入目镜11和物镜13,通过物镜13后的激光聚焦为光刀,通过目镜11的激光经由CCD采集和计算机8处理实现对图像信息的采集,其中目镜11与45°反射镜15之间设置滤光片14。电子目镜10置于目镜11内,电子目镜10通过数据线9与计算机8连接。
如图2所示,为一种通过激光对血管内脂肪堵塞物进行清除的装置的血管疏通部件包括:激光器1、组合光纤2、计算机7、显微操作仪3、金属网6;其中组合光纤2为成像光纤和溶脂光纤结合的组合光纤,由显微操作仪3实现对组合光纤的控制,金属网6为涂覆有脂肪酶的金属网,用于清除血管内多余的脂肪。金属网6为可伸缩型,将手柄贴近血管时金属网探出,分解脂肪酶。
采用本发明的装置对血管内脂肪堵塞物进行清除时,打开计算机8,随时监控血管内情况:首先,使用图1所示光刀部件对堵塞血管前段开刀,即血液首先流过的区域,创口须刚好能够使组合光纤探入血管4。在光纤与血管壁接触的地方加入填充物,防止血液流出,同时使用显微操作仪3对组合光纤进行显微操作,将组合光纤探入血管4,使光纤轴向方向与血管4壁内壁平行;随后,使用图1所示光刀部件在堵塞血管尾部,即血液后流过的区域开刀,创口大小须与金属网6的金属柄直径相近,并在金属柄与血管接触的地方加入填充物防止血液流出,金属柄探入长度刚好为血管壁厚度,然后金属网6在血管内撑开,紧挨血管壁,金属网平面与血管轴向垂直;再者打开图2疏通血管部件的激光器7,激光沿溶脂光纤传导至溶脂光纤锥部。同时成像光纤开始实时检测。实时监测,逐步溶脂,使血管壁上的脂肪从血管壁上脱落,而后随血液流动,到达金属网被分解成小分子,从而达到疏通血管的目的,此步骤需根据血管堵塞程度的不同选用不同间隙金属网。其中金属网6间隙的大小可调,通过调节金属网6的间隙,用于清除血管内多余的脂肪。其中金属网6间隙的大小调节可以通过增加或减少金属网的数量的实现。
以上所述,仅为本发明较佳的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应以所述权利要求的保护范围为准。
