In recent years, with the continuous development of social economy, endoscopy is more and more widely used in our daily life, but many people are not very clear about the knowledge of endoscope. In fact, endoscope generally refers to the medical equipment that enters the human body through various channels to observe the internal conditions of the human body. Let's take a look at some of the main work of endoscope maintenance.

　　使用中的注意事项硬管内窥镜在手术过程中受到损坏的现象并不多，虽然会与人体的组织如肌肉、黏膜、骨骼等有接触和磕碰，但是这些磕碰是轻微的，不会造成窥镜的损坏，因为它只是起观察的作用，不是其他器械的受力点。但是在使用其他器械时，尤其是咬合力较大的钳、剪类器械应注意镜管的前端不要伸进器械的咬合区内，以免误伤镜管。在使用这类器械时，有时医生为了看清楚咬合区的组织，把窥镜伸得很靠近组织，器械咬合时窥镜没有退回，误伤了窥镜。手术时如注意让器械的咬合口全部都在窥镜的观察范围内就可以避免此类事故发生。

　　During the operation, hard tube endoscope is not damaged in many cases. Although it may contact and bump with human tissues such as muscle, mucous membrane and bone, these bumps are slight and will not cause damage to the endoscope, because it is only used for observation, not the force bearing point of other instruments. However, when using other instruments, especially forceps and scissors with large bite force, the front end of the lens tube should not extend into the occlusal area of the instrument, so as to avoid accidental injury to the lens tube. When using this kind of instrument, sometimes the doctor extends the endoscope very close to the tissue in order to see clearly the tissue in the occlusal area. When the instrument is occluded, the endoscope does not return and the endoscope is injured by mistake. This kind of accident can be avoided if the occlusal mouth of the instrument is all within the scope of the endoscope.

　　有些手术窥镜是在鞘管内使用，在更换其他角度窥镜或插拔器械时，应注意动作要轻，不可用力过猛。尤其是插拔窥镜过程中，当遇到阻力拔不动时应仔细查找原因，必要时应连同鞘管一起拔取，不要用蛮力。当窥镜配合激光汽化、高频电切、微波等光电技术进行手术时，应注意窥镜前端与点的距离，保证窥镜前端不被电击或烧灼。当感觉到刨刀工作异常或照度突然降低时，有可能窥镜已经受损，应及时更换，以免造成更大损失。一般重要手术，应有一套备用窥镜和关键器械，在发现问题时可以从容地更换;如果使用角度不合适的窥镜或不配套的器械勉强手术，也容易造成窥镜的损坏。
                   

　　Some operating endoscopes are used in the sheath tube. When replacing the endoscope with other angles or inserting and pulling out the instrument, the action should be light and the force should not be too strong. Especially in the process of inserting and pulling out the endoscope, when the resistance is encountered, the reason should be carefully found out. If necessary, it should be pulled out together with the sheath tube, without brute force. When the endoscope is operated with laser vaporization, high-frequency electrosurgical excision, microwave and other photoelectric technologies, attention should be paid to the distance between the front end of the endoscope and the treatment point to ensure that the front end of the endoscope is not shocked or burned. When the planer blade works abnormally or the illumination suddenly decreases, the endoscope may have been damaged, so it should be replaced in time to avoid greater loss. For general important surgery, there should be a set of spare endoscopes and key instruments, which can be easily replaced when problems are found; if the endoscope with inappropriate angle or incompatible equipment is used to force the operation, it is easy to cause damage to the endoscope.

　　怎样维护硬管内窥镜硬管内窥镜应有专人专柜保管，放在专用的包装箱内，内衬柔软的海绵或聚氨酯泡沫。所有窥镜和手术器械都要码放整齐，不得交叉重叠放置，确保箱盖盖好后，内部的窥镜和器械不会在搬运时相互撞击。由于内窥镜的镜管很薄，受到挤压、磕碰、折弯、落地等情况就会弯曲变形，导致镜片破损或光轴偏移而造成图像不清楚或不能使用，所以从包装箱中取出或放入硬管内窥镜时，应双手平托，轻轻地取出或放入，切忌提起一段拽出。窥镜放在托盘等硬质容器内移动时，注意与其他器械分开放置，不要过分颠簸，以免碰撞到窥镜。包装箱内应备有干燥剂保持箱内干燥。

　　How to maintain the rigid tube endoscope hard tube endoscope should be kept in a special cabinet, placed in a special packing box, lined with soft sponge or polyurethane foam. All endoscopes and surgical instruments should be stacked in order and should not be overlapped. After the box cover is covered, the internal endoscope and instruments will not collide with each other during transportation. As the endoscope tube is very thin, it will bend and deform when it is squeezed, bumped, bent or landed on the ground, resulting in lens damage or optical axis offset, resulting in unclear or unusable images. Therefore, when taking out or putting the hard tube endoscope out of the packaging box, both hands should be held flat and gently taken out or put in. It is forbidden to lift a section of the endoscope out. When the endoscope is placed in the tray and other hard containers, it should be placed separately from other instruments, and should not be unduly bumped to avoid collision with the endoscope. There should be desiccant in the packing box to keep it dry.

　　普通的硬管内窥镜都不耐高温高压，主要是由于封装胶在高温下会变质、变形，窥镜就会开胶进水，所以不可用煮沸和高压蒸汽等高温高压的方法。大多数硬管内窥镜的损坏都是由于不注意保养、磕碰、落地等原因造成的。也有个别生产厂的封装胶、封装技术、封装结构有问题，造成窥镜进水、开胶的现象，这些都是可以修复的。硬管内窥镜虽然是娇贵的医疗器械，但是在正常的临床手术或观察中是不容易出现问题的。只要使用得法、精心维护、细心保养，医生们可以放心使用，硬管内窥镜也会发挥的效益。

　　Ordinary hard tube endoscopes are not resistant to high temperature and high pressure. The main reason is that the sealing glue will deteriorate and deform under high temperature, and the endoscope will open glue and water into the endoscope. Therefore, it can not be disinfected by boiling and high-pressure steam and other high-temperature and high-pressure methods. Most of the damage of hard tube endoscope is due to careless maintenance, bumping, landing and other reasons. There are also individual manufacturers of packaging glue, packaging technology, packaging structure problems, resulting in endoscope water, open phenomenon, these can be repaired. Although rigid tube endoscope is a delicate medical device, it is not easy to have problems in normal clinical operation or observation. As long as it is used properly, carefully and carefully, doctors can use it at ease, and the hard tube endoscope will also play the greatest benefit.
