內(nèi)窺鏡設(shè)備鏡頭起霧和污染怎么處理?

  隨著現(xiàn)代醫(yī)學(xué)技術(shù)的發(fā)展,微創(chuàng)外科手術(shù)在臨床上廣泛開(kāi)展,而腹腔鏡外科技術(shù)是外科微創(chuàng)化的重要組成部分。清晰的手術(shù)視野是腹腔鏡手術(shù)的關(guān)鍵,因此腔鏡鏡頭的防霧處理關(guān)重要。在進(jìn)行腔鏡手術(shù)過(guò)程中,由于體腔溫度和體外溫度相差較大,部分水蒸氣遇到冷的腔鏡鏡頭后容易凝聚形成一層霧,從而影響術(shù)野呈現(xiàn)在顯示器上的清晰度,影響手術(shù)操作。多年來(lái),臨床采用傳統(tǒng)鏡頭預(yù)熱方法進(jìn)行防霧處理,但該方法在實(shí)際應(yīng)用中,經(jīng)常會(huì)發(fā)生熱鹽水撒出、燙傷、鏡頭倒翻等現(xiàn)象,增加了術(shù)中污染和鏡頭損壞的幾率。
  With the development of modern medical technology, minimally invasive surgery is widely carried out in clinic, and laparoscopic surgery is an important part of minimally invasive surgery. Clear surgical field of vision is the key to the safety of laparoscopic surgery, so the anti fog treatment of endoscopic lens is very important. In the process of endoscopic surgery, due to the large difference between the body cavity temperature and the external temperature, some of the water vapor is easy to condense and form a layer of fog after encountering the cold endoscopic lens, thus affecting the clarity of the surgical field on the display and the operation. For many years, the traditional lens preheating method has been used to prevent fogging in clinic, but in practical application, hot salt water is often spilled, scalded and lens overturned, which increases the probability of intraoperative pollution and lens damage.
  鏡頭總是模糊不清,反復(fù)擦拭鏡頭,將會(huì)浪費(fèi)大量時(shí)間,也會(huì)帶來(lái)不因素。這就要求扶鏡手要善于快速處理鏡頭起霧及污染問(wèn)題,盡可能長(zhǎng)久的保持視野的清晰,接下來(lái)就由內(nèi)窺鏡維修公司給大家分享一下方法。
  The lens is always blurry. Repeatedly wiping the lens will waste a lot of time and bring unsafe factors. This requires that the hand holding the mirror should be good at dealing with the problem of lens fogging and pollution quickly, and keep the vision clear for as long as possible. Next, the endoscope maintenance company will share the solutions.
  鏡頭起霧和污染的方法主要有:
  The main solutions to fog and pollution of lens are as follows:
 ?。?)購(gòu)置帶鏡頭自加熱的腔鏡設(shè)備,但大部分無(wú)此功能;
  (1) Purchase the cavity mirror equipment with lens self heating, but most brands do not have this function;
 ?。?)鏡頭涂抹防霧劑,貴、成本高;
  (2) Lens coating antifogging agent, expensive, high cost;
 ?。?)碘伏紗布擦拭,成本較低,視野易發(fā)黃;
  (3) Iodophor gauze wipe, low cost, easy to yellow vision;
 ?。?)將鏡頭回縮 Trocar內(nèi),利用鏡頭 Trocar 內(nèi)注入的相對(duì)低溫的 CO2 氣流使視野變清晰,但易反復(fù);
  (4) The lens is retracted into trocar, and the field of vision is clear by the relatively low temperature CO2 air flow injected into trocar, but it is easy to repeat;
 ?。?)保溫杯裝熱水浸泡鏡頭,水溫保持在60 ~ 70℃,開(kāi)始浸泡鏡頭時(shí)間要稍長(zhǎng),約 1 分鐘,好讓鏡頭充分預(yù)熱,高于腹腔內(nèi)溫度。此后,每次鏡頭模糊后浸泡時(shí)間僅需幾秒即可。此法過(guò)程較為繁瑣。
  (5) The lens shall be soaked in hot water in a sterilized heat preservation cup. The water temperature shall be kept at 60-70 ℃, and the lens shall be soaked for a little longer time, about 1 minute, so as to fully preheat the lens, which is higher than the temperature in the abdominal cavity. After that, it only takes a few seconds to soak the lens after each blur. The process of this method is complicated.
  另外每次置入鏡頭前需將的密封墊內(nèi)的組織或血液清理干凈,可以通過(guò)旋轉(zhuǎn)鏡身來(lái)避開(kāi) Trocar下端的血液;進(jìn)出動(dòng)作要迅速,避免鏡身在體外太久而降溫。
  In addition, the tissue or blood in the gasket should be cleaned before each lens is put into the lens, and the blood at the lower end of trocar can be avoided by rotating the mirror body; the movement in and out should be rapid, so as to prevent the mirror body from cooling for too long in vitro.
  當(dāng)急性大出血污染鏡頭時(shí),切不可拔出鏡頭擦拭,這樣可能會(huì)錯(cuò)失處理的好時(shí)機(jī),此時(shí)可以借助臟器漿膜面(多選擇未被污染的胃、腸漿膜面)快速而輕柔地擦拭鏡頭。不要選擇系膜或網(wǎng)膜表面,可能使鏡頭沾染油脂而更加模糊;也不要選擇肝臟或脾臟這類實(shí)質(zhì)性臟器,防止損傷。當(dāng)術(shù)者出血后,扶鏡手應(yīng)重新擦拭鏡頭。
  When the lens is polluted by acute massive hemorrhage, the lens must not be pulled out for wiping, which may miss the good opportunity of treatment. At this time, the lens can be wiped quickly and gently with the help of the visceral serous surface (mostly the unpolluted gastric and intestinal serous surface). Do not choose the surface of the mesentery or omentum, which may make the lens stained with grease and more fuzzy; do not choose the liver or spleen, which is a kind of substantive organ, to prevent damage. When the surgeon solves the bleeding, the lens should be wiped again by the hand holding the mirror.
  為使手術(shù)進(jìn)程自然順暢,扶鏡手應(yīng)盡可能少的擦拭鏡頭。這就需要扶鏡手時(shí)刻做好對(duì)鏡頭的保護(hù)。比如在能量平臺(tái)刀頭燒灼組織時(shí)應(yīng)將鏡頭適當(dāng)退回規(guī)避調(diào)為遠(yuǎn)距,防止組織液或血液飛濺污染鏡頭,待燒灼完成適時(shí)調(diào)回原來(lái)視距。
  In order to make the operation process natural and smooth, the hand holding the mirror should wipe the lens as little as possible. This requires the hand holding the mirror to protect the lens at all times. For example, when the knife head of the energy platform burns tissue, the lens should be properly returned to avoid being adjusted to a long distance to prevent tissue fluid or blood splashing from polluting the lens. When the burning is completed, the original sight distance should be adjusted in time.
  扶鏡手的任務(wù)是為手術(shù)者提供清晰穩(wěn)定的手術(shù)圖像。且隨著手術(shù)進(jìn)程變化,提供遠(yuǎn)近范圍和角度適當(dāng)?shù)囊曇?。也就是說(shuō),扶鏡手充當(dāng)?shù)氖切g(shù)者“雙眼”的作用。這就要求扶鏡手要對(duì)手術(shù)過(guò)程步驟及術(shù)者的手術(shù)習(xí)慣爛熟于胸,要跟手術(shù)者保持足夠的默契。
  The task of the hand holding the mirror is to provide the surgeons with clear and stable surgical images. With the change of the operation process, it can provide a proper field of vision. In other words, the hand holding the mirror acts as the "eyes" of the performer. This requires that the hand holding the mirror should be familiar with the operation procedure and the operation habit of the operator, and keep enough tacit understanding with the operator.
