硬管内窥镜在手术过程中受到损坏的现象并不多，磕碰是轻微的，不会造成窥镜的损坏，因为它只是起观察的作用，不是其他器械的受力点。但也要多加注意一些事项，内窥镜设备维修人员为您解析。

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时，尤其是咬合力较大的钳、剪类器械应注意镜管的前端不要伸进器械的咬合区内，以免误伤镜管。

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.

在使用这类器械时，有时医生为了看清楚咬合区的组织，把窥镜伸得很靠近组织，器械咬合时窥镜没有退回，误伤了窥镜。手术时如注意让器械的咬合口全部都在窥镜的观察范围内就可以避免此类事故发生。

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。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 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.

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，应注意窥镜前端与治疗点的距离，保证窥镜前端不被电击或烧灼。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，确认窥镜前端与治疗点的距离，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 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。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。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。

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。更多相关内容就来我们网站http://www.jiangrenyiliao.cn进行咨询吧！

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.
