内窥镜是1853年法国医生德索米奥创制的。内窥镜是一种常用的医疗器械。由头端、弯曲部、插入部、操作部、导光部组成。使用时先将内窥镜导光部接到配套的冷光源上，然后将插入部导入预检查的器官，控制操作部可直接窥视有关部位的病变。

The first endoscope in the world was created by French doctor Desomio in 1853. Endoscope is a commonly used medical device. Composed of head end, bending part, insertion part, operation part, and light guide part. When using, first connect the endoscope's light guide to the matching cold light source, and then guide the insertion part into the pre examination organ to control the operation department to directly observe the lesions in the relevant areas.

早的内窥镜被应用于直肠检查。医生在病人的肛门内插入一根硬管，借助于蜡烛的光亮，观察直肠的病变。这种方法所能获得的诊断资料有限，病人不但很痛苦，而且由于器械很硬，造成穿孔的危险很大。尽管有这些缺点，内窥镜检查一直在继续应用与发展，并逐渐设计出很多不同用途与不同类型的器械。

The earliest endoscopes were used for rectal examination. The doctor inserted a hard tube into the patient's anus and observed the lesion in the rectum with the light of a candle. The diagnostic data obtained by this method is limited, and patients not only suffer greatly, but also have a high risk of perforation due to the hard instruments. Despite these drawbacks, endoscopic examination has continued to be applied and developed, gradually designing many different types of instruments for different purposes.

1936年，美国人斯卡夫进行了脑室镜检试验，直到1962年，才由德国人古奥和弗累斯梯尔创立了脑室镜检法。从此形成一整套镜检法系列。

In 1936, an American named Scarf conducted a ventriculoscopic examination, and it was not until 1962 that the method of ventriculoscopic examination was established by German authors G ü o and F ü rster. From then on, a complete series of mirror inspection methods was formed.
