　　發(fā)展歷史

　　Development history

　　內(nèi)窺鏡是人類窺視自身體內(nèi)器官的重要工具。古希臘名醫(yī)，有著醫(yī)藥之父之稱的希波克拉底（Hippocrates，約公元前460-前370）曾描述過(guò)一種直腸診視器，該診視器與我們今天所用的器械十分相似。類似的診視器還發(fā)現(xiàn)于龐培遺跡（Pompeii，意大利古都，公元79年火山爆發(fā)，全城淹沒），這些診視器曾被用于窺視陰道與子宮頸，檢查直腸，并用于檢視耳、鼻內(nèi)。當(dāng)時(shí)進(jìn)行這些檢查時(shí)利用的是自然光線。內(nèi)窺鏡的真正發(fā)展還是起于近代，一般可將其發(fā)展階段分為：硬管式窺鏡、半可屈式內(nèi)窺鏡、纖維內(nèi)窺鏡、超聲與電子內(nèi)窺鏡等階段。硬管式內(nèi)窺鏡的發(fā)展經(jīng)歷了兩個(gè)階段：即開放式硬管內(nèi)窺鏡階段與含有光學(xué)系統(tǒng)的硬管內(nèi)窺鏡階段。

　　Endoscope is an important tool for humans to observe their internal organs. Hippocrates, the renowned physician of ancient Greece and known as the father of medicine, described a rectal sight that was very similar to the instruments we use today. Similar examination devices have also been found in the Pompeii ruins (the ancient capital of Italy, where a volcano erupted in 79 AD and the entire city was submerged). These examination devices were once used to observe the vagina and cervix, examine the rectum, and examine the ears and nose. At that time, natural light was used for these inspections. The true development of endoscopes dates back to modern times and can generally be divided into stages such as rigid tube endoscopes, semi flexible endoscopes, fiber endoscopes, ultrasound and electronic endoscopes. The development of rigid tube endoscopes has gone through two stages: the open rigid tube endoscope stage and the rigid tube endoscope stage containing an optical system.

　　基本結(jié)構(gòu)與工作原理

　　Basic structure and working principle

　　硬管內(nèi)窺鏡主要由光學(xué)成像系統(tǒng)和照明系統(tǒng)組成：光學(xué)部分外觀看是一個(gè)細(xì)長(zhǎng)的金屬管子，而里面裝著一個(gè)由許多透鏡組成的完整的光學(xué)系統(tǒng)。光學(xué)成像系統(tǒng)由物鏡系統(tǒng)、轉(zhuǎn)像系統(tǒng)、目鏡系統(tǒng)三大系統(tǒng)組成。被觀察物經(jīng)物鏡所成的倒像，通過(guò)轉(zhuǎn)像系統(tǒng)將倒像轉(zhuǎn)為正像，并傳輸?shù)侥跨R，再由目鏡放大后，為人眼所觀察。如圖1所示。為構(gòu)成不同的視向角，需加入不同的棱鏡。不同用途的內(nèi)窺鏡根據(jù)使用要求制作成不同的外形、外徑、長(zhǎng)度，以達(dá)到使用所需的要求。照明傳輸系統(tǒng)由光導(dǎo)纖維組成，將冷光源的光經(jīng)過(guò)光導(dǎo)纖維傳輸?shù)絻?nèi)窺鏡前端，照亮被觀察物。

　　A rigid tube endoscope is mainly composed of an optical imaging system and an illumination system: the optical part is a slender metal tube for external viewing, while inside it is a complete optical system composed of many lenses. The optical imaging system consists of three major systems: the objective lens system, the conversion system, and the eyepiece system. The inverted image of the observed object formed by the objective lens is converted into a positive image through a conversion system and transmitted to the eyepiece. After being magnified by the eyepiece, it is observed by the human eye. As shown in Figure 1. To form different viewing angles, different prisms need to be added. Endoscopes for different purposes are made into different shapes, outer diameters, and lengths according to usage requirements to meet the required requirements. The lighting transmission system is composed of optical fibers, which transmit the light from the cold light source to the front end of the endoscope through the optical fibers, illuminating the observed object.

　　維護(hù)保養(yǎng)與注意事項(xiàng)

　　Maintenance and Precautions

　　隨著使用硬管內(nèi)窺鏡的范圍擴(kuò)大，各科醫(yī)生使用硬管內(nèi)窺鏡頻率越來(lái)越高。硬管內(nèi)窺鏡是比較嬌貴的醫(yī)療器械，但是只要能夠正確的使用和維護(hù)，就可以避免損壞。

　　With the expansion of the scope of using rigid endoscopes, doctors from various departments are using them more frequently. Hard tube endoscope is a relatively delicate medical device, but as long as it can be used and maintained correctly, damage can be avoided.

　　維護(hù)保養(yǎng)

　　Maintenance and upkeep

　　1

　　one

　　硬管內(nèi)窺鏡使用完后應(yīng)沖洗干凈，把水漬涼干，鏡頭前端有污漬時(shí)應(yīng)用鏡頭紙、棉簽或細(xì)紗布輕輕擦拭。

　　After using the hard tube endoscope, it should be rinsed clean and the water stains should be dried. If there are stains on the front end of the lens, lens paper, cotton swabs, or fine gauze should be gently wiped.

　　2

　　two

　　硬管內(nèi)窺鏡應(yīng)有專人專柜保管，放在專用的包裝箱內(nèi)，內(nèi)襯柔軟的海綿或聚氨酯泡沫。

　　The rigid tube endoscope shall be kept in a special cabinet by a specially assigned person, placed in a special packing box, and lined with soft sponge or polyurethane foam.

　　3

　　three

　　所有硬管內(nèi)窺鏡和手術(shù)器械都要碼放整齊，不得交叉重疊放置，確保箱蓋蓋好后，內(nèi)部的窺鏡和器械不會(huì)在搬運(yùn)時(shí)相互撞擊。

　　All rigid endoscopes and surgical instruments must be neatly stacked, without overlapping or crossing, to ensure that after the box cover is closed, the internal endoscopes and instruments will not collide with each other during transportation.

　　4

　　four

　　取出或放入硬管內(nèi)窺鏡時(shí)，應(yīng)雙手平托，輕拿輕放。由于內(nèi)窺鏡的鏡管很薄，受到擠壓、磕碰、折彎、落地等情況就會(huì)彎曲變形，導(dǎo)致鏡片破損或光軸偏移而造成圖像不清楚或不能使用，所以從包裝箱中取出或放入硬管內(nèi)窺鏡時(shí)，應(yīng)雙手平托輕輕地取出或放入，切忌提起一段拽出。

　　When removing or placing a rigid tube endoscope, it should be held flat with both hands and handled gently. Due to the thin tube of the endoscope, it may bend and deform when subjected to compression, collision, bending, landing, etc., resulting in lens damage or optical axis deviation, causing unclear or unusable images. Therefore, when taking out or placing a hard tube endoscope from the packaging box, it should be gently taken out or placed with both hands flat, and avoid lifting and pulling it out.

　　5

　　five

　　硬管內(nèi)窺鏡放在托盤等硬質(zhì)容器內(nèi)移動(dòng)時(shí)，注意與其他器械分開放置，不要過(guò)分顛簸，以免碰撞到窺鏡。

　　When moving the rigid endoscope in a tray or other hard container, be careful to separate it from other instruments and avoid excessive shaking to avoid colliding with the endoscope.

　　6

　　six

　　包裝箱內(nèi)應(yīng)備有干燥劑保持箱內(nèi)干燥。

　　There should be a desiccant inside the packaging box to keep it dry.

　　7

　　seven

　　有些硬管內(nèi)窺鏡不耐高溫高壓，這主要是因?yàn)槠溏R端封裝用的環(huán)氧樹脂膠在高溫高壓下會(huì)開膠而造成鏡管內(nèi)進(jìn)水，光學(xué)系統(tǒng)進(jìn)水后就會(huì)產(chǎn)生視野模糊，所以這類內(nèi)窺鏡不能用煮沸和高壓蒸汽等高溫高壓的方法消毒。

　　Some hard tube endoscopes are not resistant to high temperature and high pressure, mainly because the epoxy resin adhesive used for the sealing of the endoscope end will open under high temperature and high pressure, causing water to enter the endoscope tube. After the optical system enters the water, the field of view will be blurred. Therefore, these endoscopes cannot be disinfected by high-temperature and high-pressure methods such as boiling and high-pressure steam.

　　注意事項(xiàng)

　　matters needing attention

　　1

　　one

　　在使用其他器械時(shí)，尤其是咬合力較大的鉗、剪類器械應(yīng)注意鏡管的前端不要伸進(jìn)器械的咬合區(qū)內(nèi)，以免誤傷鏡管。

　　When using other instruments, especially pliers and scissors with high biting force, attention should be paid to not inserting the front end of the mirror tube into the bite area of the instrument to avoid accidental injury to the mirror tube.

　　2

　　two

　　有些手術(shù)窺鏡是在鞘管內(nèi)使用，在更換其他角度窺鏡或插拔器械時(shí)，應(yīng)注意動(dòng)作要輕，不可用力過(guò)猛。尤其是插拔窺鏡過(guò)程中，當(dāng)遇到阻力拔不動(dòng)時(shí)應(yīng)仔細(xì)查找原因，必要時(shí)應(yīng)連同鞘管一起拔取，不要用蠻力。

　　Some surgical endoscopes are used inside the sheath. When replacing other angle endoscopes or inserting or removing instruments, attention should be paid to moving gently and not applying too much force. Especially during the process of inserting and removing the endoscope, if there is resistance and it cannot be pulled out, the reason should be carefully investigated. If necessary, the sheath should be pulled out together, and brute force should not be used.

　　3

　　three

　　當(dāng)窺鏡配合激光汽化、高頻電切、微波等光電技術(shù)進(jìn)行手術(shù)時(shí)，應(yīng)注意窺鏡前端與治療點(diǎn)的距離，保證窺鏡前端不被電擊或燒灼。

　　When the endoscope is used in conjunction with laser vaporization, high-frequency electric cutting, microwave and other optoelectronic technologies for surgery, 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 electrocuted or burned.

　　4

　　four

　　當(dāng)配合刨削器來(lái)切除病變組織時(shí)，如耳鼻喉科、骨科的臨床手術(shù)中已經(jīng)廣泛使用，需要控制刀頭的旋轉(zhuǎn)部分始終在窺鏡的觀察范圍內(nèi)，在手術(shù)范圍較大時(shí)，應(yīng)先停止刀頭轉(zhuǎn)動(dòng)，再移動(dòng)窺鏡，然后在窺鏡監(jiān)視下移動(dòng)刀頭，到合適部位后再開機(jī)刨削。

　　When using a scraper to remove diseased tissue, such as in clinical surgeries in otolaryngology and orthopedics, it is necessary to control the rotation of the blade head to always be within the observation range of the endoscope. When the surgical range is large, the rotation of the blade head should be stopped first, and then the endoscope should be moved. Under the supervision of the endoscope, the blade head should be moved to the appropriate location before turning on the scraper.

　　5

　　five

　　當(dāng)內(nèi)窺鏡出現(xiàn)圖像模糊、視線不清等狀況時(shí)，要及時(shí)與廠家或維修機(jī)構(gòu)聯(lián)系，切不可繼續(xù)盲目使用而造成手術(shù)事故。

　　When the endoscope shows blurry images or unclear vision, it is necessary to promptly contact the manufacturer or maintenance organization, and not continue to blindly use it, which may cause surgical accidents.

　　腹腔鏡

　　laparoscope

　　與電子胃鏡類似，是一種帶有微型攝像頭的器械。腹腔鏡手術(shù)與傳統(tǒng)手術(shù)相比，具有切口小、痛苦小、恢復(fù)快等優(yōu)點(diǎn)，深受患者的歡迎，尤其是術(shù)后瘢痕小、又符合美學(xué)要求，青年病人更樂(lè)意接受，微創(chuàng)手術(shù)是外科發(fā)展的總趨勢(shì)和追求目標(biāo)。目前，腹腔鏡手術(shù)的金標(biāo)準(zhǔn)是膽囊切除術(shù)，一般地說(shuō)，大部分普通外科的手術(shù)，腹腔鏡手術(shù)都能完成。如闌尾切除術(shù)，胃、十二指腸潰瘍穿孔修補(bǔ)術(shù)、疝氣修補(bǔ)術(shù)、結(jié)腸切除術(shù)、脾切除術(shù)、腎上腺切除術(shù)，還有卵巢囊腫摘除、宮外孕、子宮切除等，隨著腹腔鏡技術(shù)的日益完善和腹腔鏡醫(yī)生操作水平的提高，幾乎所有的外科手術(shù)都能采用這種手術(shù)。

　　Similar to electronic gastroscopy, it is a device with a miniature camera. Compared with traditional surgery, laparoscopic surgery has the advantages of smaller incisions, less pain, and faster recovery, which is highly welcomed by patients. Especially with small postoperative scars and aesthetic requirements, young patients are more willing to accept minimally invasive surgery, which is the overall trend and pursuit goal of surgical development. At present, the gold standard for laparoscopic surgery is cholecystectomy. Generally speaking, most general surgical procedures can be performed using laparoscopic surgery. Such as appendectomy, repair of gastric and duodenal ulcer perforation, hernia repair, colectomy, splenectomy, adrenalectomy, as well as removal of ovarian cysts, ectopic pregnancy, hysterectomy, etc., with the increasing improvement of laparoscopic technology and the improvement of laparoscopic doctors' operating level, almost all surgical procedures can adopt this type of surgery.

　　維護(hù)保養(yǎng)與注意事項(xiàng)

　　Maintenance and Precautions

　　隨著使用硬管內(nèi)窺鏡的范圍擴(kuò)大，各科醫(yī)生使用硬管內(nèi)窺鏡頻率越來(lái)越高。硬管內(nèi)窺鏡是比較嬌貴的醫(yī)療器械，但是只要能夠正確的使用和維護(hù)，就可以避免損壞。

　　With the expansion of the scope of using rigid endoscopes, doctors from various departments are using them more frequently. Hard tube endoscope is a relatively delicate medical device, but as long as it can be used and maintained correctly, damage can be avoided.

　　維護(hù)保養(yǎng)

　　Maintenance and upkeep

　　1

　　one

　　硬管內(nèi)窺鏡使用完后應(yīng)沖洗干凈，把水漬涼干，鏡頭前端有污漬時(shí)應(yīng)用鏡頭紙、棉簽或細(xì)紗布輕輕擦拭。

　　After using the hard tube endoscope, it should be rinsed clean and the water stains should be dried. If there are stains on the front end of the lens, lens paper, cotton swabs, or fine gauze should be gently wiped.

　　2

　　two

　　硬管內(nèi)窺鏡應(yīng)有專人專柜保管，放在專用的包裝箱內(nèi)，內(nèi)襯柔軟的海綿或聚氨酯泡沫。

　　The rigid tube endoscope shall be kept in a special cabinet by a specially assigned person, placed in a special packing box, and lined with soft sponge or polyurethane foam.

　　3

　　three

　　所有硬管內(nèi)窺鏡和手術(shù)器械都要碼放整齊，不得交叉重疊放置，確保箱蓋蓋好后，內(nèi)部的窺鏡和器械不會(huì)在搬運(yùn)時(shí)相互撞擊。

　　All rigid endoscopes and surgical instruments must be neatly stacked, without overlapping or crossing, to ensure that after the box cover is closed, the internal endoscopes and instruments will not collide with each other during transportation.

　　4

　　four

　　取出或放入硬管內(nèi)窺鏡時(shí)，應(yīng)雙手平托，輕拿輕放。由于內(nèi)窺鏡的鏡管很薄，受到擠壓、磕碰、折彎、落地等情況就會(huì)彎曲變形，導(dǎo)致鏡片破損或光軸偏移而造成圖像不清楚或不能使用，所以從包裝箱中取出或放入硬管內(nèi)窺鏡時(shí)，應(yīng)雙手平托輕輕地取出或放入，切忌提起一段拽出。

　　When removing or placing a rigid tube endoscope, it should be held flat with both hands and handled gently. Due to the thin tube of the endoscope, it may bend and deform when subjected to compression, collision, bending, landing, etc., resulting in lens damage or optical axis deviation, causing unclear or unusable images. Therefore, when taking out or placing a hard tube endoscope from the packaging box, it should be gently taken out or placed with both hands flat, and avoid lifting and pulling it out.

　　5

　　five

　　硬管內(nèi)窺鏡放在托盤等硬質(zhì)容器內(nèi)移動(dòng)時(shí)，注意與其他器械分開放置，不要過(guò)分顛簸，以免碰撞到窺鏡。

　　When moving the rigid endoscope in a tray or other hard container, be careful to separate it from other instruments and avoid excessive shaking to avoid colliding with the endoscope.

　　6

　　six

　　包裝箱內(nèi)應(yīng)備有干燥劑保持箱內(nèi)干燥。

　　There should be a desiccant inside the packaging box to keep it dry.

　　7

　　seven

　　有些硬管內(nèi)窺鏡不耐高溫高壓，這主要是因?yàn)槠溏R端封裝用的環(huán)氧樹脂膠在高溫高壓下會(huì)開膠而造成鏡管內(nèi)進(jìn)水，光學(xué)系統(tǒng)進(jìn)水后就會(huì)產(chǎn)生視野模糊，所以這類內(nèi)窺鏡不能用煮沸和高壓蒸汽等高溫高壓的方法消毒。

　　Some hard tube endoscopes are not resistant to high temperature and high pressure, mainly because the epoxy resin adhesive used for the sealing of the endoscope end will open under high temperature and high pressure, causing water to enter the endoscope tube. After the optical system enters the water, the field of view will be blurred. Therefore, these endoscopes cannot be disinfected by high-temperature and high-pressure methods such as boiling and high-pressure steam.

　　注意事項(xiàng)

　　matters needing attention

　　1

　　one

　　在使用其他器械時(shí)，尤其是咬合力較大的鉗、剪類器械應(yīng)注意鏡管的前端不要伸進(jìn)器械的咬合區(qū)內(nèi)，以免誤傷鏡管。

　　When using other instruments, especially pliers and scissors with high biting force, attention should be paid to not inserting the front end of the mirror tube into the bite area of the instrument to avoid accidental injury to the mirror tube.

　　2

　　two

　　有些手術(shù)窺鏡是在鞘管內(nèi)使用，在更換其他角度窺鏡或插拔器械時(shí)，應(yīng)注意動(dòng)作要輕，不可用力過(guò)猛。尤其是插拔窺鏡過(guò)程中，當(dāng)遇到阻力拔不動(dòng)時(shí)應(yīng)仔細(xì)查找原因，必要時(shí)應(yīng)連同鞘管一起拔取，不要用蠻力。

　　Some surgical endoscopes are used inside the sheath. When replacing other angle endoscopes or inserting or removing instruments, attention should be paid to moving gently and not applying too much force. Especially during the process of inserting and removing the endoscope, if there is resistance and it cannot be pulled out, the reason should be carefully investigated. If necessary, the sheath should be pulled out together, and brute force should not be used.

　　3

　　three

　　當(dāng)窺鏡配合激光汽化、高頻電切、微波等光電技術(shù)進(jìn)行手術(shù)時(shí)，應(yīng)注意窺鏡前端與治療點(diǎn)的距離，保證窺鏡前端不被電擊或燒灼。

　　When the endoscope is used in conjunction with laser vaporization, high-frequency electric cutting, microwave and other optoelectronic technologies for surgery, 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 electrocuted or burned.

　　4

　　four

　　當(dāng)配合刨削器來(lái)切除病變組織時(shí)，如耳鼻喉科、骨科的臨床手術(shù)中已經(jīng)廣泛使用，需要控制刀頭的旋轉(zhuǎn)部分始終在窺鏡的觀察范圍內(nèi)，在手術(shù)范圍較大時(shí)，應(yīng)先停止刀頭轉(zhuǎn)動(dòng)，再移動(dòng)窺鏡，然后在窺鏡監(jiān)視下移動(dòng)刀頭，到合適部位后再開機(jī)刨削。

　　When using a scraper to remove diseased tissue, such as in clinical surgeries in otolaryngology and orthopedics, it is necessary to control the rotation of the blade head to always be within the observation range of the endoscope. When the surgical range is large, the rotation of the blade head should be stopped first, and then the endoscope should be moved. Under the supervision of the endoscope, the blade head should be moved to the appropriate location before turning on the scraper.

　　5

　　five

　　當(dāng)內(nèi)窺鏡出現(xiàn)圖像模糊、視線不清等狀況時(shí)，要及時(shí)與廠家或維修機(jī)構(gòu)聯(lián)系，切不可繼續(xù)盲目使用而造成手術(shù)事故。

　　When the endoscope shows blurry images or unclear vision, it is necessary to promptly contact the manufacturer or maintenance organization, and not continue to blindly use it, which may cause surgical accidents.
