Description

一种支撑架OCT成像导管
【技术领域】
本发明涉及一种成像导管装置,特别涉及一种支撑架OCT成像导管。
【背景技术】
光学相干断层成像(Optical Coherence Tomography,简称OCT) 应用现代计算机图像处理,将先进光学技术与超灵敏探测器合为一体,已发展成为一种新兴的断层成像诊断技术。OCT 技术以其极高的探测灵敏度与噪声抑制能力、高分辨率、非接触性和非破坏性无损伤和在体检测无辐射等优越性以及造价低、结构简单等优点,在材料科学和生物医学等领域的无创检测方面有着越来越广泛的应用。目前,OCT已经应用于诊断眼科、皮肤科、心血管***、消化***等疾病。
OCT利用低相干光源进行测量,空间分辨率高,样品的微小移动就会影响检测结果,在活体使用时,呼吸、心跳、肌肉收缩等均会造成检测部位(例如:消化道、呼吸道、血管等)的微小移动,这将会引起图像的模糊,不利于临床诊断。现有的OCT设备因为此类技术问题造成的图像质量低下,已经影响了医生对疾病的准确判断。如果能降低检测时人体组织的微小移动或者使OCT探头与检测部位的相对位置不变,则能避免移动引起的图像模糊,大大提高了成像质量,获得准确的反映病灶真实情况的清晰图像,更有利于医生对疾病的诊断。因此,研究出一种能解决以上问题的OCT导管将有广泛的应用前景。
【发明内容】
本发明要解决的问题是提供一种支撑架OCT成像导管,提供一种支撑架OCT成像导管,用于介入手术中,通过在导管上设置支撑架结构,起到了稳定探头与人体腔道的作用,提高了成像质量。
为实现上述目的,本发明采取的技术方案为:
一种支撑架OCT成像导管,包括接口端,进注管,支撑架外管,成像内管,中枢管,导管上设有中枢管,所述中枢管分别与接口端,进注管,支撑架外管与成像内管相连;所述支撑架外管前端设有多筋结构的支撑架;所述支撑架外管内为成像内管;所述进注管末端有进注口,用于清洗液或造影剂的注入;所述接口端连接OCT设备。
进一步地,所述支撑架由透光性良好的材料制成。
进一步地,所述成像内管前端内部设有成像探头,探头在扫描过程中始终处于支撑架内部。
进一步地,所述中枢管上设有回拉手柄,回拉手柄通过控制支架头端的前后移动来实现支撑架的张开和闭合。
与现有技术相比,本发明具有如下有益效果:
该导管前端设有多筋结构的支撑架,在使用时,支撑架撑住人体腔道,使得探头与人体腔道的位置保持相对稳定,避免了人体组织的微小移动引起的图像模糊。支撑架采用透光性良好的材料制成,不影响探头在支撑架内部扫描。本发明的导管能够有效提高成像质量,有助于降低手术风险,提高手术成功率,更好的指导手术的进行。
【附图说明】
图1是本发明的一种支撑架OCT成像导管。
【具体实施方式】
为使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解,下面结合具体实施方式,进一步阐述本发明。
1-接口端,2-进注口,3-进注管,4-支撑架外管, 5-支撑架,6-支撑架头端,7-成像内管,8-中枢管,9-回拉手柄。
实施例:
如图1所示,
一种支撑架OCT成像导管,包括接口端1,进注管3,支撑架外管4,成像内管7,中枢管8,导管上设有中枢管8,所述中枢管8分别与接口端1,进注管3,支撑架外管4与成像内管7相连;所述支撑架外管4前端设有多筋结构的支撑架5;所述支撑架外管4内为成像内管7;所述进注管3末端有进注口2,用于清洗液或造影剂的注入;所述接口端1连接OCT设备。
在手术中,呼吸、心跳、肌肉收缩等均会造成检测部位(例如:消化道、呼吸道、血管等)的微小移动,这将会引起图像的模糊,本发明的导管的支撑架结构在使用中将撑住检测部位的腔道,探头会在支撑架内部进行扫描,所以保证了探头与人体腔道的位置相对稳定,避免了人体组织的移动导致的成像模糊,而且支撑架材料采用透光性良好的材料,不会影响成像质量。
其中,所述支撑架5由透光性良好的材料制成。
其中,所述成像内管7前端内部设有成像探头,探头在扫描过程中始终处于支撑架5内部。
其中,所述中枢管8上设有回拉手柄9,回拉手柄9通过控制支架头端的前后移动来实现支撑架5的张开和闭合。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解,本发明不受上述实施例的限制,上述实施例和说明书中描述的只是说明本发明的原理,在不脱离本发明精神和范围的前提下,本发明还会有各种变化和改进,这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
