In recent years, with the continuous development of social economy, endoscope is more and more widely used in our daily life, but many people don't know much about endoscope. In fact, endoscope generally refers to medical instruments that enter the human body through various pipelines 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。

Precautions in use: hard tube endoscopes are rarely damaged during operation. Although they will contact and bump with human tissues such as muscles, mucous membranes and bones, these bumps are slight and will not cause damage to the endoscope, because they only play the role of observation and are not the force point of other instruments. However, when using other instruments, especially forceps and scissors with large bite force, it should be noted that the front end of the mirror tube should not extend into the bite area of the instrument, so as to avoid accidental injury to the mirror tube.

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。

When using this kind of instrument, sometimes the doctor extends the endoscope very close to the tissue in order to see the tissue in the occlusal area clearly. When the instrument occludes, the endoscope does not return and injures the endoscope by mistake. Such accidents can be avoided if all the occlusal openings of the instrument are within the observation range 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。

Some surgical endoscopes are used in the sheath. When replacing other angle endoscopes or inserting and unplugging instruments, pay attention to light action and do not use too much force. Especially in the process of inserting and removing the endoscope, when it cannot be pulled out due to resistance, carefully find out the reason. If necessary, pull it together with the sheath without brute force.

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，应注意窥镜前端与治疗点的距离，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。

When the endoscope is operated with laser vaporization, high-frequency electroresection, microwave and other photoelectric technologies, pay attention 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 you feel that the planer is working abnormally or the illumination suddenly decreases, the endoscope may have been damaged and should be replaced in time to avoid greater loss.

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。

For general important operations, there should be a set of spare endoscopes and key instruments, which can be replaced calmly when problems are found; It is also easy to cause damage to the endoscope if it is forced to operate with an inappropriate angle endoscope or mismatched instruments.
