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。德国狼牌内窥镜设备维修人员提醒，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 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.

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，应注意窥镜前端与点的距离，保证窥镜前端不被电击或烧灼。初次使用这些器械时，主刀医生应反复练习，掌握窥镜图像中物距和实际物距的关系，确认窥镜前端与点的近距离，以便在实际手术中应用自如。

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、骨科的临床手术中已经广泛使用刨削器来切除病变组织。其刀头锋利、硬度高、旋转速度快、力矩大，如果削到内窥镜，窥镜必损无疑。

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.

在此类手术中要注意调整冲洗和吸引的速度，随时保证窥镜图像清晰不被血污遮挡，控制刀头的旋转部分始终在窥镜的观察范围内，在手术范围较大时，应先停止刀头转动，再移动窥镜，然后在窥镜监视下移动刀头，到合适部位后再开机刨削。

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.

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。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。您有什么问题或者需求就来我们网站http://www.jiangrenyiliao.cn咨询吧！

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.
