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.

內(nèi)窺鏡維修

Endoscope maintenance

使用中的注意事項硬管內(nèi)窺鏡在手術(shù)過程中受到損壞的現(xiàn)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。

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.

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(yīng)注意鏡管的前端不要伸進器械的咬合區(qū)內(nèi)，以免誤傷鏡管。在使用這類器械時，有時醫(yī)生為了看清楚咬合區(qū)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(shù)時如注意讓器械的咬合口全部都在窺鏡的觀察范圍內(nèi)就可以避免此類事故發(fā)生。

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. 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(shù)窺鏡是在鞘管內(nèi)使用，在更換其他角度窺鏡或插拔器械時，應(yīng)注意動作要輕，不可用力過猛。尤其是插拔窺鏡過程中，當(dāng)遇到阻力拔不動時應(yīng)仔細(xì)查找原因，必要時應(yīng)連同鞘管一起拔取，不要用蠻力。當(dāng)窺鏡配合激光汽化、高頻電切、微波等光電技術(shù)進行手術(shù)時，應(yīng)注意窺鏡前端與治療點的距離，保證窺鏡前端不被電擊或燒灼。

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. 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.

當(dāng)感覺到刨刀工作異常或照度突然降低時，有可能窺鏡已經(jīng)受損，應(yīng)及時更換，以免造成更大損失。一般重要手術(shù)，應(yīng)有一套備用窺鏡和關(guān)鍵器械，在發(fā)現(xiàn)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(shù)，也容易造成窺鏡的損壞。

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. 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.
