用于诊断和治疗目的的可弯性食管镜,已大部代替了通常的硬直食管镜。可弯性食管镜的光源在镜体之外,光线和形象都通过涂有反光物质的玻璃纤维束来传送。通过食管镜的管腔,可以进行吹气、冲水、吸引、钳取活检.刷取细胞学标本和钳取异物;还可用Eder Puestow扩张器进行良性食管狭窄的扩张治疗,食管镜远端可向四个方向弯曲,因此可以从胃内观察贲门情况,这对诊断贲门恶性病变、裂孔疝、裂孔括约肌功能不全等疾病很有帮助。通过可弯性食管镜还可摄取高质量的照片,利用对兰光敏感的胶片可以很容易地确诊食管静脉曲张。
Flexible esophagoscopes for diagnostic and therapeutic purposes have largely replaced conventional hard-tip esophagoscopes. Translucent esophagoscope light source in the mirror body outside, the light and the image are transmitted through the glass fiber coated with reflective material to send. Through the lumen of esophagoscopy, you can inflatable, flushing, suction, forceps biopsy brushing cytology specimens and clamp to take foreign body; also available Eder Puestow dilator for the expansion of benign esophageal stenosis, the distal end of esophagoscopy Curved in four directions, so you can observe the cardia situation from the stomach, which is diagnosed cardia malignant lesions, hiatal hernia, sphincter perfusion disorders such as helpful. High-quality photos can also be taken with a flexible esophagoscope, and esophageal varices can be easily diagnosed using blue-sensitive film.
