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。德國狼牌內窺鏡設備維修人員提醒，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 scopes are used in the sheath tube. When replacing other angle scopes or inserting and pulling out instruments, attention should be paid to the light action and not to use too much force. The maintenance personnel of the German Wolf brand endoscope equipment reminded that, especially during the insertion and removal of the endoscope, when the resistance is encountered, the reason should be carefully found out, and if necessary, it should be removed together with the sheath tube, not with 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。初次使用這些器械時，主刀醫生應反復練習，掌握窺鏡圖像中物距和實際物距的關系，確認窺鏡前端與點的近距離，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 electrocuted or burned. When using these instruments for the first time, the surgeon should practice repeatedly to master the relationship between the object distance in the endoscope image and the actual object distance, and confirm the close distance between the front end of the endoscope and the treatment point, so as to apply them 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。

At present, the planer has been widely used in the clinical operations of otolaryngology and orthopedics to remove the diseased tissue. Its blade is sharp, high hardness, fast rotation speed and large torque. If it cuts into the endoscope, the endoscope will be damaged.

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，然后在窺鏡監視下移動刀頭，到合適部位后再開機刨削。

In such operations, attention should be paid to adjusting the speed of washing and suction to ensure that the image of the endoscope is clear and not covered by blood stains at any time. The rotating part of the knife head should always be within the scope of observation of the endoscope. When the scope of operation is large, the rotation of the knife head 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 then the machine should be turned on for planing after reaching the appropriate position.

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。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。您有什么問題或者需求就來我們網站http://www.dibeisi.top咨詢吧！

When you feel that the planer is working abnormally or the illumination is suddenly reduced, it is possible that the endoscope has been damaged, and you should replace it in time to avoid causing greater losses. For general important surgery, there should be a set of spare endoscope and key instruments, which can be easily replaced when problems are found; It is also easy to cause damage to the endoscope if the endoscope with improper angle or mismatched instruments are used to operate reluctantly.
