Description

一种OCT导管内部回抽装置 技术领域
本发明涉及一种医疗器械技术领域，尤其涉及一种OCT导管内部回抽装置。
背景技术
光学干涉断层成像技术(Optical Coherence Tomography,OCT)是一种基于弱相干光干涉原理，通过检测不同组织对入射的弱相干光的背向反射或散射信号得到生物组织的二维或三维结构的光学成像技术。它由美国麻省理工学院的研究小组于1991年首次提出，因为其具有成像快、分辨率高、非侵入式等优点，在医学领域获得了广泛应用。
目前，国内外关于光学干涉断层成像技术的研究主要集中于眼科、人体皮肤科以及心血管领域的OCT技术和设备,并没有相应开发实际可用于人体开放管腔道内的OCT医疗设备。一般的OCT设备只适用于单一位置组织内的成像，但是单个截面所表现的信息往往较为有限，不方便亦不利于医疗人员精准确定病灶的类型及大小，因此必须加入可带动扫描导管沿轴向方向移动的模块，从而实现对人体开放管腔道组织进行一定轴向距离的扫描成像。通过一段轴向距离的回抽成像可以更加清晰地判断组织结构的形态、病变部位的位置及尺寸等关键信息，由于OCT扫描技术可以获取探测组织的径向深度信息，因此在进行轴向回抽扫描成像的同时可得到该探测组织的三维结构。
现有的OCT轴向回抽扫描模块在扫描时都是采用OCT导管整体沿轴向回抽移动的解决方案，该方案存在如下几点不足：第一、OCT导管的整体回抽移动容易造成患者体内管腔道粘膜的摩擦损伤；第二、OCT导管的整体回抽移动容易出现抖动现象，从而导致重构图像出现畸变或变形；第三、OCT导管的整 体回抽移动与患者体内管腔道表面摩擦时容易引起患者的二次不适，进而导致患者治疗配合度下降以及由此带来的相应问题。因此，迫切需要一种全新的、能够解决上述不足的OCT导管回抽装置。
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OCT导管内部回抽装置，其能解决OCT导管整体回抽移动出现抖动的技术问题。
本发明的目的采用如下技术方案实现：
一种OCT导管内部回抽装置，包括光纤、胶管和光纤接头，所述胶管内设置有空腔，所述光纤的一端穿过胶管的一端进入胶管内的空腔中，所述光纤的另一端设置有光纤接头，所述光纤接头用于与一旋转电机相接。
进一步地，还包括固定装置，所述固定装置上设置有第一通道，所述光纤穿过该第一通道，所述固定装置设置于光纤接头与胶管之间。
进一步地，还包括光纤固定管，所述光纤固定管设置于第一通道内，所述光纤固定管与光纤固定。
进一步地，所述固定装置上设置有第二通道，所述第二通道与第一通道连通，且所述第二通道内设置有压强平衡模块，所述压强平衡模块用于维持第一通道与第二通道内的压强不变。
进一步地，所述压强平衡模块为气压补偿块或者压强平衡气囊。
进一步地，所述第一通道和第二通道内设置有折射率匹配液。
进一步地，还包括第一密封圈和第二密封圈，所述第一密封圈设置于压强平衡模块处，所述第一密封圈用于防止折射率匹配液溢出，所述第二密封圈设置于第一通道处，所述第二密封圈用于防止折射率匹配液溢出。
进一步地，所述第一密封圈为O形圈或者方形圈或者组合线圈，所述第二 密封圈为O形圈或者方形圈或者组合线圈。
进一步地，还包括接头固定管，所述接头固定管设置于光纤接头端外部，所述接头固定管用于将该光纤接头固定于一机器上。
进一步地，所述接头固定管设置有卡扣，所述接头固定管通过卡扣卡接于光纤接头，所述卡扣在旋转一定角度后脱离接头固定插销。
相比现有技术，本发明的有益效果在于：
本发明的OCT导管内部回抽装置能够有效解决导管回抽造成的患者体内管腔道粘膜的摩擦损伤，提高了患者诊断的舒适性。
附图说明
图1为实施例一的OCT导管内部回抽装置的结构图；
图2为实施例二的OCT导管内部回抽装置的结构图。
附图标记：1、光纤接头；2、光纤固定管；3、固定装置；4、第二密封圈；5、第一密封圈；6、第二通道；7、胶管；8、空腔；9、光纤；10、压强平衡气囊；11、气压补偿块；12、第一通道。
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，需要说明的是，在不相冲突的前提下，以下描述的各实施例之间或各技术特征之间可以任意组合形成新的实施例。
实施例一：
如图1所示，本实施例提供了一种OCT导管内部回抽装置，包括光纤9、胶管7、光纤接头1、固定装置3、压强平衡模块、第一密封圈5、第二密封圈4和接头固定管，所述胶管7内设置有空腔8，所述光纤9的一端穿过胶管7的一 端进入胶管7内的空腔8中，所述光纤9的另一端设置有光纤接头1，所述光纤接头1用于与一旋转电机相接；所述接头固定管设置于光纤接头1处外部，所述接头固定管用于将该光纤接头1固定于一机器上，所述光纤接头1为SC-APC光纤接头；在现有技术中，胶管7与光纤9是固定在一起的，在进行OCT导管的回抽的时候是光纤9连接着胶管7一起移动，从而使得胶管7与人体管腔道之间会有摩擦，从而容易造成患者体内管腔道粘膜的摩擦损伤；而本发明通过将光纤9与胶管7分离的情况，使得在光纤9回抽的过程中，不会存在与人体管腔道之间的摩擦，使得或者在诊断的过程中更加的舒适；
所述固定装置3上设置有第一通道12，所述光纤9穿过该第一通道12，所述固定装置3设置于光纤接头1与胶管7之间；所述光纤固定管2设置于第一通道12内，所述光纤固定管2与光纤9固定,；所述固定装置3上还设置有第二通道6，所述第二通道6与第一通道12相连通，且所述第二通道6内设置有压强平衡模块，所述压强平衡模块用于维持第一通道12与第二通道6内的压强不变；所述压强平衡模块为气压补偿块11，所述第一通道12和第二通道6内设置有折射率匹配液，所述第一密封圈5设置于压强平衡模块处，所述第一密封圈5用于防止折射率匹配液穿过压强平衡模块流出去从而造成第一通道12与第二通道6内的压强泄漏，所述第二密封圈4设置于第一通道12处，所述第二密封圈4用于防止折射率匹配液溢出；所述第一密封圈5为O形圈或者方形圈或者组合线圈，所述第二密封圈4为O形圈或者方形圈或者组合线圈。
医用导管(也即是光纤9)从OCT导管内部回抽装置中轴线穿出，医用导管在OCT导管内部回抽装置内的部分，由光纤固定管2包裹，能实现整体同轴转动以及来回平移，光纤固定管2固定在SC-APC接头上。SC-APC接头与接头外固定管由两根pin接头内固定插销连接组成整体，丝杆步进电机上的丝杆螺母 与回抽部件组的SC-APC接头末端传动连接。
当OCT导管内部回抽装置处于初始状态时，接头外固定管顶端的卡扣卡在pin接头外固定插销上，不能实现回抽部件组的来回抽动；处于工作状态时，医务人员启动丝杆步进电机并带动回抽部件组同轴转动，当接头外固定管较初始状态旋转九十度角后，卡扣脱离pin接头外固定插销，医务人员可以操控丝杆步进电机控制回抽部件组移动，实现一定纵深范围的OCT成像。
压强平衡装置内部注有机油(也即是折射率匹配液)，其中第一密封圈5和第二密封圈4起到了阻挡机油进入回抽部件组的作用。处于工作状态，丝杆步进电机带动回抽部件组回抽时，压强平衡装置内部的气压补偿块11向外平移，推动机油填补回抽部件组平移后带来的真空间隙平衡装置内外压强，丝杆步进电机带动回抽部件组推送时，压强平衡器件向内平移，这种压强平衡结构保证光纤固定管2以及光纤9能够顺利平移，通过设置气压补偿块11从而使得其内部达到压强平衡，使得在光纤回抽过程中并不会产生很大的阻力。
实施例二：
在实施例一中压强平衡模块采用的是气压补偿块11，在本实施例中采用的压强平衡气囊10；其作用目的是一样的，都是为了平衡该装置内的压强，不过一种是通过气压补偿块11移动的方式，一种是通过压强平衡气囊10扩大缩小的问题，可以根据具体实际的情况来对其进行分析来确定那种情况采用何种的压强平衡方式。
上述实施方式仅为本发明的优选实施方式，不能以此来限定本发明保护的范围，本领域的技术人员在本发明的基础上所做的任何非实质性的变化及替换均属于本发明所要求保护的范围。
