/></section><section><br /></section><section><span>1954年英国Hopkings及Kapany研究了纤维的精密排列,有效地解决了纤维束的图像传递,为纤维光学的实用奠定了基础。</span></section><section><br /></section><section><p><img

/></section><section><span>1956年,Wild和Reid最早将机械旋转超声探头应用于经直肠腔内超声诊断前列腺疾患,一些无内镜视野的腔内超声探头在直肠、妇科及泌尿科疾病诊断中得到应用。</span></section><p><br /></p><section><br /></section><section><span>到了60年代,内窥镜逐渐发展成型,1960年10月美国膀胱镜制造者公司(ACMI)向Hirschowitz提供了第一个商业纤维内窥镜,紧接着日本Olympus厂在光导纤维胃镜基础上,加装了活检装置及照相机,有效地显示了胃照相术。</span></section><section><br /></section><section><br /></section><section><span>Olympus厂首创前端弯角机构,Machida厂采用外部冷光源,使光亮度大增,可发现小病灶,视野进一步扩大,可以观察到十二指肠。随着附属装置的不断改进,如手术器械、摄影系统的发展,使纤维内镜不但可用于诊断,且可用于手术治疗。</span></section><section><br /></section><section><p><img

/></p><p><span>1992年Vilmann等首次报道了内镜超声引导下胰腺病变的细针吸取细胞学检查,即通常所说的EUS-FNA(Endoscopic ultrasonography guided fine needle aspiration)。</span><span>此后,EUS引导下细针穿刺活检拓展到经支气管针吸活检。</span><span>EUS特别是EUS引导下的介入诊断技术在某些方面(如微小病灶诊断,病变性质判定,肿瘤分期准确性等)已展现出CT、MRI、ERCP、MRCP等影像学技术难以比拟的优势,可与现有其他影像技术联合提高诊断准确性。</span></p><p><br /></p><p><span>随着临床应用的不断深入,超声内镜技术的发展也日新月异。</span><span>例如,基于CCD/CMOS图像传感器的电子胃肠镜取代纤维胃肠镜,使超声内镜的光学图像分辨率也得到了显著提升;</span><span>具备更大超声视野的纵轴扫描超声内镜、提供更大钳道的超声内镜的开发,使EUS引导下的介入诊疗更加便捷;</span><span>具有三维重建功能、二次谐波成像、造影谐波成像及弹性成像功能的新技术也在超声内镜中得到应用。</span></p><p><br

/></p><p><span>此外,还有近年才刚刚有成品产品的胶囊内镜,胶囊内窥镜是一种使用微型无线摄像头拍摄消化道照片的装置。</span><span>胶囊内窥镜摄像头位于您吞咽的维生素大小的胶囊内。</span><span>当胶囊穿过你的消化道时,相机会拍摄数千张照片,这些照片会传输到你腰部佩戴的记录器上。</span></p><p><br /></p><p><p><img
