在临床为满足院感要求，需要保持内窥镜的干净、卫生，防止细菌、病毒传播感染，一般都会进行消毒、干燥，而插入管的硬化及老化状况大多是由于长时间的消毒浸泡导致或是消毒药水浓度稀释比例不对或使用酸化水，使插入管表皮变质、泛黄、老化，严重的可能产生破裂。下面内窥镜设备维修厂家为您讲解下预防措施。

In order to meet the requirements of hospital infection in clinic, it is necessary to keep the endoscope clean and sanitary to prevent bacterial and viral infection. Generally, disinfection and drying will be carried out. However, the hardening and aging of the insertion tube are mostly caused by long-term disinfection immersion, or the dilution ratio of the disinfectant solution is incorrect, or the use of acidified water, resulting in deterioration, yellowing and aging of the insertion tube skin, which may cause serious rupture. The endoscope equipment maintenance manufacturer will explain the preventive measures for you.

插入管表皮一旦变质、泛黄、老化，就可能产生破裂。禁止用绝缘胶带包住裂口处，这样做非但起不到密封作用，长时间的浸泡或弯曲裂口都会导致消毒药水慢慢渗入镜体，导光部进水就会浸泡坏PCB板无图像，操作部进水就会导致手轮、钢丝严重锈蚀，插入如进水会导致导光束硬化、CCD损坏。

Once the skin of the insertion tube deteriorates, yellows and ages, it may break. It is forbidden to wrap the crack with insulating tape. This will not only play a sealing role, but also lead to the long-term immersion or bending of the crack will cause the disinfectant to seep into the mirror body slowly, the light guide part will be soaked in water, the PCB board will be damaged without image, the operation part will cause serious rust on the handwheel and steel wire, and the insertion of water will lead to the hardening of the light guide beam and CCD damage.

预防或解决措施：

Prevention or solution measures:

（1）消毒液体配置严格按照要就进行；

(1) The disinfection liquid shall be prepared in strict accordance with the requirements;

（2）关注患者情况，患者因为检查带来的不适感，常常导致多次呕吐，要密切关注牙垫是否脱落，对于不能配合或是浅麻无意识患者必要时可让一助手协助固定牙垫，避免患者牙齿对镜体损伤。

(2) Pay attention to the patient's condition. The patient often vomits many times because of the discomfort caused by the examination. Pay close attention to whether the dental pad falls off. For patients who cannot cooperate or are unconscious of light anesthesia, an assistant can help fix the dental pad if necessary to avoid the damage of the patient's teeth to the mirror body.

内窥镜在手术过程中受到损坏的现象并不多，虽然会与人体的组织如肌肉、黏膜、骨骼等有接触和磕碰，但是这些磕碰是轻微的，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。

There are not many damages to the endoscope during the operation. Although it will contact and bump with human tissues such as muscle, mucosa, bone, etc., these bumps are slight and will not cause damage to the endoscope, because it is only for observation, not the force point of other instruments. However, when using other instruments, especially forceps and scissors with large bite force, 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。您有怎样的疑惑或者需求就来我们网站http://www.jiangrenyiliao.cn进行咨询吧！

When using this kind of instrument, sometimes doctors stretch the endoscope very close to the tissue in order to see clearly the tissue in the occlusal area. When the instrument occludes, the endoscope does not return, and the endoscope is injured by mistake. During operation, such accidents can be avoided if all the occlusal openings of the instruments are within the scope of observation of the endoscope.
