沒(méi)有圖像

No images

（1）原因分析：沒(méi)有圖像是內(nèi)窺鏡常出現(xiàn)的故障，物鏡的損壞或者進(jìn)水、內(nèi)管柱狀透鏡的碎裂都會(huì)出現(xiàn)沒(méi)有圖像的現(xiàn)象，而內(nèi)管透鏡只要其中一個(gè)柱狀透體碎裂就會(huì)導(dǎo)致沒(méi)有圖像。

(1) Reason analysis: Lack of image is a common malfunction in endoscopes. Damage to the objective lens, water ingress, or fragmentation of the inner tube cylindrical lens can result in lack of image. However, as long as one of the cylindrical transparent bodies of the inner tube lens is fragmented, it can lead to lack of image.

（2）排除方法：首先，借助放大鏡檢查鏡身有沒(méi)有凹痕或者彎曲；其次，看物鏡端有沒(méi)有破裂；后，檢查鏡子是否因密封性能不好造成進(jìn)水。

(2) Troubleshooting: Firstly, use a magnifying glass to check for dents or bends in the mirror body; Secondly, check if the objective lens end is broken; Afterwards, check the mirror for water ingress due to poor sealing performance.

圖像發(fā)暗

Image darkening

（1）原因分析：圖像發(fā)暗通常是由光源引起的，物鏡和光纖上的污物及硬鏡管內(nèi)有潮氣進(jìn)入也會(huì)使圖像發(fā)暗。

(1) Reason analysis: Image darkening is usually caused by the light source, and dirt on the objective lens and optical fiber, as well as moisture entering the hard lens tube, can also darken the image.

（2）排除方法：首先，采用更換法檢查光纖是不是斷裂太多（一般情況下光纖斷裂不超過(guò)15%可以繼續(xù)使用，一旦超過(guò)15%就會(huì)出現(xiàn)圖像發(fā)暗的現(xiàn)象）；其次，檢查硬鏡的物鏡和光纖上有沒(méi)有污物及灰塵；后，檢查鏡子的密封性是否完好。

(2) Exclusion method: Firstly, use the replacement method to check if the optical fiber has too many fractures (generally, the optical fiber can continue to be used if the fracture does not exceed 15%, and once it exceeds 15%, the image will appear dark); Secondly, check for dirt and dust on the objective lens and optical fiber of the hard lens; Afterwards, check if the sealing of the mirror is intact.

圖像發(fā)黃

Image yellowing

（1）原因分析：圖像發(fā)黃大多數(shù)情況是由于物鏡組故障導(dǎo)致。

(1) Cause analysis: The yellowing of the image is mostly caused by a malfunction of the objective lens group.

（2）排除方法：內(nèi)窺鏡設(shè)備維修人員來(lái)查看機(jī)器上的色彩參數(shù)是否設(shè)置正確；其次，檢查是不是有潮氣進(jìn)入內(nèi)鏡；后，觀察物鏡組上的黏膠有沒(méi)有老化引起的發(fā)黃。

(2) Troubleshooting method: Endoscopic equipment maintenance personnel should check whether the color parameters on the machine are set correctly; Secondly, check if there is moisture entering the endoscope; Afterwards, observe whether the adhesive on the objective lens group has yellowing caused by aging.

圖像內(nèi)發(fā)現(xiàn)灰塵

Dust found in the image

（1）原因分析：圖像內(nèi)有灰塵一是物鏡、目鏡外有污物或者是整個(gè)光學(xué)系統(tǒng)比較臟引起的，二是柱狀透體與間隔管柱在使用期間有摩擦現(xiàn)象，也會(huì)產(chǎn)生細(xì)小粉末，時(shí)間長(zhǎng)以灰塵狀反映在圖像上。

(1) Reason analysis: There is dust inside the image. Firstly, there is dirt outside the objective lens and eyepiece, or the entire optical system is relatively dirty. Secondly, there is friction between the columnar transparent body and the spacing tube column during use, which can also produce small powder, which is reflected in the image as dust over time.

（2）排除方法：檢查物鏡和目鏡上有沒(méi)有污物、灰塵和劃痕。

(2) Troubleshooting: Check for dirt, dust, and scratches on the objective lens and eyepiece.

霧狀圖像

Foggy image

（1）原因分析：產(chǎn)生霧狀圖像主要是有水汽進(jìn)入，特別是由于老化，水汽從物鏡端、目鏡端及光纖封口處進(jìn)入鏡體。

(1) Reason analysis: The formation of foggy images is mainly due to the entry of water vapor, especially due to aging. Water vapor enters the lens body from the objective lens end, eyepiece end, and fiber seal.

（2）排除方法：檢查物鏡和目鏡端的密封性，檢查光纖接口處的密封性。

(2) Troubleshooting: Check the sealing of the objective and eyepiece ends, and check the sealing of the fiber optic interface.

圖像變形有陰影

Image deformation with shadows

（1）原因分析：圖像變形有陰影多是由人為因素導(dǎo)致的工作管受力彎曲變形所致，也有可能是成像系統(tǒng)里面出現(xiàn)松動(dòng)引起的。

(1) Reason analysis: Image deformation and shadows are often caused by human factors such as bending and deformation of the work tube under force, or it may be caused by looseness in the imaging system.

（2）排除方法：轉(zhuǎn)動(dòng)鏡子檢查鏡身是否扭曲或者彎曲。

(2) Troubleshooting: Rotate the mirror to check if the mirror body is twisted or bent.

硬性內(nèi)窺鏡是一種貴重、使用頻率較高的精密設(shè)備，看似結(jié)實(shí)，其實(shí)較為脆弱，在使用的各個(gè)環(huán)節(jié)都可能導(dǎo)致鏡子的損壞。所以要好好對(duì)其使用維護(hù)，更多事項(xiàng)就來(lái)我們網(wǎng)站http://www.daybang.cn咨詢吧！

A rigid endoscope is a valuable and frequently used precision device that appears sturdy but is actually fragile, and can cause damage to the mirror in all stages of use. So we need to properly use and maintain it, and more matters will come to our website http://www.daybang.cn Consult!
