Description

一种应用于人体开放管腔道的OCT探头
技术领域
本发明属于医疗器械技术领域,尤其涉及一种应用于人体开放管腔道的OCT探头。
背景技术
光学相干层析技术(Optical coherence Tomography,OCT)是近十年迅速发展的一种高分辨率成像技术,该技术是基于低相干光干涉原理,并与共焦显微技术相结合,检测生物组织不同深度层对入射弱相干光的后向散射波回波时间延迟及回波强度信号,通过扫描得到样品二维或者三维的高分辨率微观组织结构,从而获得被测样品在体无损的断层层析图像。OCT成像技术无需添加任何显影剂,没有电离效应和荧光效应,比传统的影像技术安全性更高,被称为“光学活检”。
相比X射线成像、超声成像及核磁共振成像技术,OCT断层扫描成像技术有着更高的分辨率,目前普遍的OCT断层扫描成像技术能达到10μm级别分辨率,比X射线及核磁共振成像技术高出两个量级。高分辨率,无损检测等优点使得OCT断层扫描成像技术在诸如眼科、皮肤科、牙科以及工艺制品检测等领域得到广泛的应用,并取得了令人满意的效果。
现行的OCT断层扫描技术都采用近红外光(如1300nm)作为探测光源,而近红外光并不能很好的穿透血管中的红细胞,所以在心血管领域应用OCT技术时必须采取短时间阻断血流或局部冲洗血管等方法来排除血管中的血液,然后进行扫描成像。这种探测方法风险较大,容易造成患者心肌缺血,而且操作复杂,对操作者有很高的操作要求。要将OCT技术广泛应用到血管造影、腔内组织(如肺部)检查等领域,提高OCT断层扫描成像技术的成像质量是关键。
目前用于血管探测的OCT探头,存在扫描探头与外部保护套之间有空气缝隙的缺陷。空气缝隙的存在使得从探头出射的光斑容易产生畸变,变成椭圆光斑,影响光束的汇聚效果,从而导致成像质量的下降。针对该问题,专利CN201520036955.2采取一种保护套管内壁与探头本体前端完全匹配的方法,虽解决了空气间隙的问题,但由于完全匹配,此时保护套管与探头本体之间具有传动关系,而OCT探头在活检时主要采用周向环形扫描的方式,这要求与人体组织接触的OCT保护套管不能进行周向环形运动。因此,寻找一种能有效提高OCT断层扫描成像质量的方法具有重要意义。
发明内容
为了克服现有技术的不足,本发明的目的在于提供一种应用于人体开放管腔道的OCT探头,其能解决在扫描成像的时候,因探头本体与外部探头护件之间存在空气间隙而造成图像不清晰的缺陷。
本发明的目的采用以下技术方案实现:
一种应用于人体开放管腔道的OCT探头,包括探头护件、探头本体、油性液体、金属线圈、探头护梢和导光光纤,所述探头本体与金属线圈匹配安装,且金属线圈安装于探头本体的后端,所述导光光纤固定于探头本体内部,所述探头护梢套接于探头本体上,所述探头护件套接于探头护梢及金属线圈上,且所述油性液体填充于探头护梢及金属线圈与探头护件之间。
优选地,还包括固定件,所述固定件用于将探头本体与探头护梢固定。其能进一步解决探头护梢与探头本体的固定的技术问题。
优选地,所述探头护件为医用圆头尼龙弹性管。其能进一步解决探头护件的材料的选取的技术问题。
优选地,所述探头护件的前端为半球形,且探头护件外径小于等于3mm。其能进一步解决探头护件的选取的技术问题。
优选地,所述固定件为医用塑料固定件或者医用不锈钢固定件。其进一步解决了固定件的材料的选取的技术问题。
优选地,所述探头护梢为医用不锈钢探头护梢。其进一步解决了探头护梢的材料的选取的技术问题。
优选地,所述油性液体与探头护件有相同的折射率。其进一步解决了导光偏移的技术问题。
优选地,还包括衔接定子,所述衔接定子用于将金属线圈与导光光纤固定。其能进一步解决金属线圈与导光光纤的固定的技术问题。
相比现有技术,本发明的有益效果在于:
本发明通过在OCT外部探头护件与探头本体之间填充油性液体,有效弥补了OCT内窥扫描成像技术在人体复杂人体开放管腔道进行扫描时,因探头本体与外部探头护件之间存在空气缝隙而造成图像不清晰的缺陷,优化了成像效果。
附图说明
图1为本发明的应用于人体开放管腔道的OCT探头的结构示意图。
附图标记:1、探头护件;2、探头本体;3、油性液体;4、金属线圈;401、衔接定子;5、探头护梢;6、导光光纤;7、固定件。
具体实施方式
下面,结合附图以及具体实施方式,对本发明做进一步描述:
如图1所示,本实施例提供了一种应用于人体开放管腔道的OCT探头,包括探头护件1、探头本体2、油性液体3、金属线圈4、固定件7、衔接定子401、探头护梢5和导光光纤6,所述探头本体2与金属线圈4匹配安装,且金属线圈4安装于探头本体2的后端,所述导光光纤6固定于探头本体2内部,探头本体2能够有效的保护脆弱的光纤,所述衔接定子401用于固定金属线圈4与导光光纤6。其可通过衔接定子401传递金属线圈4的扭矩与导光光纤6同步转动平移,使得探头使用起来更加的平稳顺畅。本实施例中所提及的的人体开放管腔道可以包括呼吸道、生殖道、肛肠道、食道、耳道、尿道、子宫腔、胃腔、口腔等,这些仅仅是作为示例性说明,并非罗列出所有的人体开放管腔道。
所述探头护梢5套接于探头本体2上,所述探头护梢5为医用不锈钢探头护梢。所述固定件7用于将探头本体2与探头护梢5固定。所述固定件7为医用塑料固定件或者医用不锈钢固定件。所述探头护件1套接于探头护梢5及金属线圈4上,所述探头护件1为医用圆头尼龙弹性管。所述探头护件1的前端为半球形,且探头护件1的外径小于等于3mm,所述油性液体3填充于探头护梢5及金属线圈4与探头护件1之间。所述油性液体3与探头护件1有相同的折射率。当其具有相同或者相近的折射率的时候,光线在出射的时候不会因为折射率不同从而导致光线的偏移,从而造成图像不清晰的情况,而不像没有油性液体3时,会使得产生的图像不清楚,并且该油性液体具有无色透明、无毒、低粘稠度的特性,这样能够进一步保证传输图像的清晰度。
对本领域的技术人员来说,可根据以上描述的技术方案以及构思,做出其它各种相应的改变以及形变,而所有的这些改变以及形变都应该属于本发明权利要求的保护范围之内。
