硬管内窥镜主要由光学成像系统和照明系统组成。光学部分外面是一根细长的金属管，里面是由许多透镜组成的完整光学系统。光学成像系统由物镜系统、图像中继系统和目镜系统三大系统组成。

Hard tube endoscope is mainly composed of optical imaging system and lighting system. Outside the optical part is a slender metal tube, and inside is a complete optical system composed of many lenses. The optical imaging system consists of objective lens system, image relay system and eyepiece system.

被观察物体的倒像由物镜形成，倒像通过图像中继系统转换为正像，然后传输到目镜，再由目镜放大供人观察眼睛。为了形成不同的视角，需要添加不同的棱镜。

The inverted image of the observed object is formed by the objective lens. The inverted image is converted into a positive image through the image relay system, and then transmitted to the eyepiece, which is enlarged by the eyepiece for human observation. In order to form different perspectives, different prisms need to be added.

不同用途的内窥镜根据使用要求制成不同的形状、外径和长度，以满足使用要求。照明传输系统由光纤组成，将冷光源的光通过光纤传输到内窥镜前端，照亮被观察物体。

Endoscopes for different purposes are made into different shapes, outer diameters and lengths according to the use requirements to meet the use requirements. The lighting transmission system is composed of optical fiber, which transmits the light of cold light source to the front end of endoscope through optical fiber to illuminate the observed object.

随着硬镜使用范围的扩大，各种医生使用硬镜的频率越来越高。刚性内窥镜是比较精密的医疗器械，但只要使用和维护得当，损坏是可以避免的。

With the expansion of the scope of use of hard mirrors, various doctors use hard mirrors more and more frequently. Rigid endoscope is a relatively precise medical device, but as long as it is used and maintained properly, the damage can be avoided.

内窥镜维修人员认为，硬管内窥镜使用后应冲洗干净，水渍应擦干。硬管内窥镜应由专人保管在专柜内，放入专用箱内，内衬软海绵或聚氨酯泡沫塑料。

The endoscope maintenance personnel believe that the hard tube endoscope should be washed clean after use, and the water stains should be wiped dry. The hard tube endoscope shall be kept in a special cabinet by a specially assigned person and placed in a special box lined with soft sponge or polyurethane foam.

所有硬管内窥镜和手术器械应堆放整齐，不得相互重叠放置。确保盖子关闭后，内部的内窥镜和器械在运输过程中不会相互碰撞。硬管内窥镜在托盘等硬质容器中移动时，注意与其他器械分开放置，不要过度碰撞，以免与内窥镜发生碰撞。

All rigid tube endoscopes and surgical instruments shall be stacked neatly without overlapping each other. Ensure that the internal endoscope and instrument will not collide with each other during transportation after the cover is closed. When the hard tube endoscope moves in the tray and other hard containers, pay attention to placing it separately from other instruments, and do not collide excessively to avoid collision with the endoscope.

取出或放置硬性内窥镜时，应双手平放，轻拿轻放。由于内窥镜的镜筒很细，在受到挤压、碰撞、弯曲、跌落等情况下会弯曲变形，导致镜片损坏或光轴偏移，导致图像不清晰或无法使用使用，所以把它从盒子里拿出来。或者在放置硬管内窥镜时，应双手轻轻取出或放入，切勿抬起拉出。

When taking out or placing the rigid endoscope, put it flat with both hands and handle it gently. Because the barrel of the endoscope is very thin, it will bend and deform under extrusion, collision, bending, falling, etc., resulting in lens damage or optical axis offset, resulting in unclear image or inability to use, so take it out of the box. Or when placing the hard tube endoscope, gently take it out or put it in with both hands, and do not lift it out.
