背景技术Background technique
目前，心脑血管疾病是危害人类健康的第一大疾病，近年来，随着科技的发展，计算机断层扫描、心血管磁共振成象、数字减影技术、血管内超声及光学相干断层成像相继应用于临床，大幅度提高了心血管疾病的诊断及治疗水平。但这些检测技术均是非直观的成像技术，医生或患者看到的是经过电脑处理过的心血管组织影像，达不到类似胃肠镜、腹腔镜那样直观的观察效果，这也成为目前制约心血管病诊疗技术继续向前发展的非常重要的因素。At present, cardiovascular and cerebrovascular diseases are the most serious diseases that endanger human health. In recent years, with the development of science and technology, computed tomography, cardiovascular magnetic resonance imaging, digital subtraction technology, intravascular ultrasound and optical coherence tomography have successively Clinical application has greatly improved the diagnosis and treatment of cardiovascular diseases. However, these detection techniques are non-intuitive imaging techniques. What doctors or patients see is computer-processed cardiovascular tissue images, which cannot achieve the intuitive observation effect similar to gastroenteroscopy and laparoscopy. It is a very important factor for the continuous development of vascular disease diagnosis and treatment technology.
血管镜法是应用血管镜得到可视图像的一种方法，血管镜研制至今已有90余年的历史，但80年代之前，由于心血管内充满血液，血管镜无法取得好的图像，都是用于心胸外科手术过程中的检查。在进入20世纪80年代以后血管镜开始装配有效阻断血流的气囊，可比较清楚地看到血管腔的变化，这才真正促进了血管镜用于临床，也开创了血管镜介入检查的时代。但由于血管镜检查时需要频繁阻断血流、开通血流，制约了血管镜的临床应用。虽然近年来出现的专利(United States Patent Number4784133)对血管镜头端做了一些改进，在头端形成了一定工作平台，但存在明显的缺陷，一是无法解决在血管镜头与心血管组织之间血液完全排空问题；二是血管镜头端较硬，并且操作相对复杂；三是无法以血管镜为工作平台进行血管狭窄或闭塞病变的介入治疗。Angioscopy is a method to obtain visual images by using angioscope. The development of angioscope has a history of more than 90 years. Examination during cardiothoracic surgery. After entering the 1980s, the angioscope began to be equipped with a balloon that effectively blocked the blood flow, and the changes in the vascular lumen could be seen more clearly. This really promoted the use of the angioscope in clinical practice, and also created an era of interventional examination of the angioscope. . However, the clinical application of angioscopy is restricted due to the need to frequently block and open blood flow during angioscopy. Although the patent (United States Patent Number 4784133) that has appeared in recent years has made some improvements to the end of the vascular lens and formed a certain working platform at the head end, there are obvious defects. First, it cannot solve the problem of blood between the vascular lens and the cardiovascular tissue. The problem of complete emptying; the second is that the end of the angioscope is hard and the operation is relatively complicated; the third is that it is impossible to use the angioscope as a working platform for interventional treatment of vascular stenosis or occlusion.

本发明为达到上述目的，包括球囊，球囊中心管，球囊血管镜头端接口，球囊中心管两端均有开口与外界相通，球囊中心管前端在球囊前端中心与球囊前端密封连接，球囊中心管管身及尾端游离，不与球囊及球囊血管镜头端接口连接；球囊血管镜头端接口衔接在球囊内部，球囊血管镜头端接口两端中空，里面为球囊血管镜头端接口内部螺旋结构。为减少球囊血管镜头端接口对球囊的损伤，球囊血管镜头端接口外面采用流线型设计。In order to achieve the above object, the present invention comprises a balloon, a balloon central tube, and a balloon end interface for blood vessels. Both ends of the balloon central tube have openings communicating with the outside world. The front end of the balloon central tube is at the center of the front end of the balloon and the Sealed connection, the tube body and tail end of the balloon central tube are free, not connected with the balloon and the end interface of the balloon vascular lens; It is the internal helical structure of the end interface of the balloon vascular lens. In order to reduce the damage to the balloon from the end interface of the balloon angiography lens, the outer surface of the end interface of the balloon angiography lens adopts a streamlined design.
本发明取得的有益效果是(1)为血管镜行血管检查及介入治疗时提供一种媒介与平台，消除了血液对图像的影响，无需阻断血流，操作简便；(2)可在血管镜直视下行血管的介入治疗，减少射线的使用，简单、方便、安全，减少患者及医护人员射线的照射。The beneficial effects obtained by the present invention are (1) to provide a medium and platform for blood vessel inspection and interventional treatment by angioscope, which eliminates the influence of blood on the image, without blocking the blood flow, and is easy to operate; (2) can be used in blood vessels The interventional treatment of the descending blood vessels directly under the mirror can reduce the use of radiation, which is simple, convenient and safe, and can reduce the radiation exposure of patients and medical staff.
