在内窥镜手术中，由于体腔温度与外界温度相差很大，有些水汽在遇到冷的内窥镜后容易凝结形成雾气，影响手术部位的清晰度显示和影响操作。那么内窥镜镜片起雾、污染怎么办？下面内窥镜设备维修人员为您进行讲解。

During endoscopic surgery, due to the great difference between the body cavity temperature and the external temperature, some water vapor is easy to condense and form fog after encountering the cold endoscope, which affects the clarity display of the surgical site and operation. What about fog and pollution of endoscope lens? The following endoscope equipment maintenance personnel will explain to you.

(1)购买带自加热镜片的内窥镜设备，但大多数品牌没有此功能；

(1) Purchase endoscope equipment with self heating lenses, but most brands do not have this function;

(2)镜片涂有防雾剂，价格昂贵，成本高；

(2) The lenses are coated with antifogging agent, which is expensive and costly;

(3)碘伏纱布擦拭成本低，视野容易变黄；

(3) Iodophor gauze has low wiping cost, and the vision is easy to turn yellow;

(4)将晶状体缩回套管针内，利用相对低温的CO2气流注入晶状体套管针，使视野清晰，但易重复；

(4) The lens is retracted into the trocar and injected into the lens trocar with relatively low temperature CO2 air flow, so that the visual field is clear but easy to repeat;

(5)将镜片放入消毒保温杯中的热水中浸泡，水温应保持在60～70℃。镜片次浸泡时间稍长，约1分钟，让镜片充分预热，高于腹腔内的温度。之后，浸泡时间只有镜片模糊后的几秒钟。这种方法的过程相当复杂。

(5) Put the lens into the hot water in the disinfection and insulation cup to soak, and the water temperature should be kept at 60~70 ℃. The immersion time of the lens is a little longer, about 1 minute, to fully preheat the lens, which is higher than the temperature in the abdominal cavity. After that, the immersion time is only a few seconds after the lens is blurred. The process of this method is quite complicated.

另外，每次放置镜片前，都要清洗垫圈内的组织或血液。旋转镜头可以避免套管针下端的血液；快速进出，避免镜体在体外时间过长造成的温度下降。

In addition, the tissues or blood in the gasket should be cleaned before each lens placement. Rotating the lens can avoid the blood at the lower end of the trocar; Fast in and out to avoid temperature drop caused by too long time outside the body.

急性出血污染内窥镜镜片时，切记不要拔出镜片擦拭，以免错过时机。这时可以用器官的浆液面（多为未污染的胃肠道浆液面）快速轻柔地擦拭镜片。

When the endoscope lens is polluted by acute bleeding, remember not to pull out the lens and wipe it to avoid missing the opportunity. At this time, you can quickly and gently wipe the lens with the plasma level of the organ (mostly the uncontaminated gastrointestinal plasma level).

不要选择系膜或大网膜的表面，这可能会导致内窥镜镜片被油脂污染而变得更加模糊；不要选择肝脏或脾脏，以防止损害。当操作者解决出血后，内窥镜手应再次擦拭内窥镜镜片。

Do not select the surface of the mesentery or greater omentum, which may cause the endoscope lens to become more blurred due to oil contamination; Do not select the liver or spleen to prevent damage. After the operator solves the bleeding, the endoscope hand shall wipe the endoscope lens again.

为使操作过程顺利，内窥镜手应尽量少擦拭内窥镜镜片，这就需要配镜助手时刻保护镜片。例如，能量平台在烧灼刀片时，应适当缩回内窥镜镜头，避免遥测，防止组织液或血液溅到镜头上，烧灼后恢复到原来的视距。更多设备相关的内容就来我们网站http://www.jiangrenyiliao.cn进行咨询了解吧！

In order to make the operation process smooth, the endoscope hand should wipe the endoscope lens as little as possible, which requires the glasses assistant to protect the lens at all times. For example, when the energy platform cauterizes the blade, the endoscope lens should be properly retracted to avoid telemetering, prevent tissue fluid or blood from splashing onto the lens, and recover to the original sight distance after cauterization.
