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.

使用中的注意事項硬管內窺鏡在手術過程中受到損壞的現象并不多，雖然會與人體的組織如肌肉、黏膜、骨骼等有接觸和磕碰，但是這些磕碰是輕微的，不會造成窺鏡的損壞，因為它只是起觀察的作用，不是其他器械的受力點。但是在使用其他器械時，尤其是咬合力較大的鉗、剪類器械應注意鏡管的前端不要伸進器械的咬合區內，以免誤傷鏡管。

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.

在使用這類器械時，有時醫生為了看清楚咬合區的組織，把窺鏡伸得很靠近組織，器械咬合時窺鏡沒有退回，誤傷了窺鏡。手術時如注意讓器械的咬合口全部都在窺鏡的觀察范圍內就可以避免此類事故發生。

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.

有些手術窺鏡是在鞘管內使用，在更換其他角度窺鏡或插拔器械時，應注意動作要輕，不可用力過猛。尤其是插拔窺鏡過程中，當遇到阻力拔不動時應仔細查找原因，必要時應連同鞘管一起拔取，不要用蠻力。

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.

當窺鏡配合激光汽化、高頻電切、微波等光電技術進行手術時，應注意窺鏡前端與點的距離，保證窺鏡前端不被電擊或燒灼。當感覺到刨刀工作異常或照度突然降低時，有可能窺鏡已經受損，應及時更換，以免造成更大損失。

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.

一般重要手術，應有一套備用窺鏡和關鍵器械，在發現問題時可以從容地更換;如果使用角度不合適的窺鏡或不配套的器械勉強手術，也容易造成窺鏡的損壞。

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.
