硬管內窺鏡在手術過程中受到損壞的現象并不多，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。但也要多加注意一些事項，內窺鏡設備維修人員為您解析。

Hard tube endoscopes are rarely damaged during surgery. The collision is slight and will not cause damage to the endoscope, because it is only for observation, not for the force bearing point of other instruments. However, we should pay more attention to some matters, and the endoscope equipment maintenance personnel will analyze them for you.

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(qū)內，以免誤傷鏡管。

However, when using other instruments, especially forceps and scissors with large bite force, it should be noted that the front end of the lens tube should not extend into the bite area of the instrument to avoid accidental injury to the lens tube.

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(fā)生。

When using this kind of instrument, sometimes the doctor extends the endoscope very close to the tissues in order to see clearly the tissues in the occlusal area, and the endoscope is not returned when the instrument is occluded, thus injuring the endoscope by mistake. This kind of accident can be avoided if all the occlusal ports of the instruments are within the observation range of the endoscope during the operation.

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 the endoscope from other angles or inserting and pulling instruments, you should be careful not to use too much force. Especially in the process of inserting and pulling the camera, when the camera cannot be pulled out due to resistance, the reason should be carefully found out. If necessary, the camera should be pulled out together with the sheath, without using 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，應注意窺鏡前端與治療點的距離，保證窺鏡前端不被電擊或燒灼。使用這些器械時，主刀醫(yī)生應反復練習，掌握窺鏡圖像中物距和實際物距的關系，確認窺鏡前端與治療點的距離，以便在實際手術中應用自如。

When the endoscope is operated with laser vaporization, high-frequency electrosection, 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 using these instruments, the surgeon in charge should practice repeatedly, master the relationship between the object distance in the endoscope image and the actual object distance, and confirm the distance between the front end of the endoscope and the treatment point, so that they can be used freely in the actual operation.

目前在耳鼻喉科、骨科的臨床手術中已經廣泛使用刨削器來切除病變組織。其刀頭鋒利、硬度高、旋轉速度快、力矩大，如果削到內窺鏡，窺鏡必損無疑。在此類手術中要注意調整沖洗和吸引的速度，隨時保證窺鏡圖像清晰不被血污遮擋，控制刀頭的旋轉部分始終在窺鏡的觀察范圍內，在手術范圍較大時，應先停止刀頭轉動，再移動窺鏡，然后在窺鏡監(jiān)視下移動刀頭，到合適部位后再開機刨削。當感覺到刨刀工作異?；蛘斩韧蝗唤档蜁r，有可能窺鏡已經受損，應及時更換，以免造成更大損失。

At present, the planer has been widely used in the clinical surgery of otorhinolaryngology and orthopedics to remove the pathological tissues. The cutter head is sharp, with high hardness, fast rotation speed and large torque. If the endoscope is cut, the endoscope will be damaged. In such operations, attention should be paid to adjusting the speed of flushing and suction, ensuring that the endoscope image is clear and not covered by blood at any time, and controlling the rotating part of the knife head is always within the observation range of the endoscope. When the operation range is large, the knife head rotation should be stopped first, then the endoscope should be moved, and then the knife head should be moved under the monitoring of the endoscope, and the machine should be started for planing after reaching the appropriate position. When you feel that the planer is working abnormally or the illumination suddenly decreases, it is possible that the camera has been damaged, and you should replace it 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(fā)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。更多相關內容就來我們網站http://tukouzhao.cn進行咨詢吧！

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