内窥镜是一种光学仪器.docVIP

内镜介绍 内窥镜是一种光学仪器，由体外经过人体自然腔道送入体内，对体内疾病进行检查。 Endoscopy is an optical instrument. Through human bodys natural orifice, it can go into the body and inspect the body’s disease. 内镜（亦称内窥镜）结构：分为镜头（带有调节镜末端角度的手柄）、镜身、分为软性镜身（非金属材料制作，多用于医学。金属材料制作的多用于工业探测）硬性镜身（金属材料制作，多用于医学）、镜末端（末端可由镜头的手柄调节各方向的角度）。 Structure: Lens (with the end mirror angle adjustment handle), mirror body, is divided into soft lens body (non-metallic materials are used for medicine, while Metallic materials for industrial exploration), rigid lens body (metal materials are used for Medicine), mirror at the end (the end of the handle of the lens by adjusting the angle of each direction). 内镜的功能是：能对弯曲管道深处探查、能在狭窄缝隙中和远距离观察和操作。能观察不能直视到的部位并进行操作，能在密封空腔内观察腔外广阔空间。可以直接观察到脏器内腔病变，确定其部位、范围，并可进行照相、活检，大大的提高了癌的诊断准确率，并可进行某些治疗。光导纤维内窥镜利用光导纤维传送冷光源，管径小，且可弯曲，检查时患者痛苦少。 Function: Deep explore the bent duct, distant surveillance and operate in the narrow gap. It can observe a site where can not see straight and operate. It can also observe a vast space in the seal cavity. It can observe organ’s cavity lesion directly, determine its location, extent, and take photos, do biopsy, which greatly improves the diagnostic accuracy of cancer, and make some treatment. Using fiber optic, optical fiber endoscope sends cold light source. It has small diameter, and can be bent, which reduces the patient’s pain. 内窥镜在各种癌症检查中现应用广泛，如胃癌、肺癌、气管癌、食管癌、直肠癌、乙状结肠癌、膀胱癌，喉癌、鼻咽癌、宫颈癌、阴道癌等。 Endoscopic are widely used in various types examination of cancer, such as gastric cancer, lung cancer, trachea cancer, esophageal cancer, rectal cancer, colon cancer, bladder cancer, laryngeal cancer, nasopharyngeal cancer, cervical cancer, vaginal carcinoma, etc. 90%以上的医院，内镜医师借助内镜设备开展内镜下临床诊疗工作。内镜下诊疗技术，已经广泛应用在临床的各专科（人体胃、肠内、腹腔内、关节腔内、颅内等狭窄缝隙内）。20多年来，我国内镜在临床诊疗工作中，发挥了很大的作用。从头到足部，广泛地应用内镜微创手术，取到很大成就，已形成一种 “特种医学”，即内镜学。 More than 90% of the hospitals, endoscopic doctor do endoscopic therapeutic with endoscopy equipment. Endoscopic therapy has been widely used in clinical specialist (human sto
