在內(nèi)窺鏡手術中，由于體腔溫度與外界溫度相差很大，有些水汽在遇到冷的內(nèi)窺鏡后容易凝結(jié)形成霧氣，影響手術部位的清晰度顯示和影響操作。那么內(nèi)窺鏡鏡片起霧、污染怎么辦？下面內(nèi)窺鏡設備維修人員為您進行講解。

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)購買帶自加熱鏡片的內(nèi)窺鏡設備，但大多數(shù)品牌沒有此功能；

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

(2)鏡片涂有防霧劑，價格昂貴，成本高；

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

(3)碘伏紗布擦拭成本低，視野容易變黃；

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

(4)將晶狀體縮回套管針內(nèi)，利用相對低溫的CO2氣流注入晶狀體套管針，使視野清晰，但易重復；

(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)將鏡片放入消毒保溫杯中的熱水中浸泡，水溫應保持在60～70℃。鏡片次浸泡時間稍長，約1分鐘，讓鏡片充分預熱，高于腹腔內(nèi)的溫度。之后，浸泡時間只有鏡片模糊后的幾秒鐘。這種方法的過程相當復雜。

(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，每次放置鏡片前，都要清洗墊圈內(nèi)的組織或血液。旋轉(zhuǎn)鏡頭可以避免套管針下端的血液；快速進出，避免鏡體在體外時間過長造成的溫度下降。

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.

急性出血污染內(nèi)窺鏡鏡片時，切記不要拔出鏡片擦拭，以免錯過時機。這時可以用器官的漿液面（多為未污染的胃腸道漿液面）快速輕柔地擦拭鏡片。

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).

不要選擇系膜或大網(wǎng)膜的表面，這可能會導致內(nèi)窺鏡鏡片被油脂污染而變得更加模糊；不要選擇肝臟或脾臟，以防止損害。當操作者解決出血后，內(nèi)窺鏡手應再次擦拭內(nèi)窺鏡鏡片。

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.

為使操作過程順利，內(nèi)窺鏡手應盡量少擦拭內(nèi)窺鏡鏡片，這就需要配鏡助手時刻保護鏡片。例如，能量平臺在燒灼刀片時，應適當縮回內(nèi)窺鏡鏡頭，避免遙測，防止組織液或血液濺到鏡頭上，燒灼后恢復到原來的視距。更多設備相關的內(nèi)容就來我們網(wǎng)站http://www.caorui.com.cn進行咨詢了解吧！

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.
