近年來，雖然內(nèi)窺鏡的質(zhì)量在穩(wěn)步提高，但作為一種異常和嬌貴的設(shè)備，每天的高壓，供應(yīng)人員的不正當(dāng)操作，手術(shù)器械的隨意擺放導(dǎo)致的碰撞等，都可能會引|起光學(xué)部件的損壞，內(nèi)窺鏡設(shè)備維修人員認(rèn)為損壞的情況大致有以下幾個方面:

In recent years, although the quality of endoscopes has been steadily improved, as an unusual and delicate equipment, the daily high-pressure sterilization, improper operation of disinfection supply personnel, collision caused by random placement of surgical instruments, etc. may cause damage to optical components. Endoscopic equipment maintenance personnel think that the damage is generally in the following aspects:

視野大小改變

Visual field size change

內(nèi)窺鏡的視野大小是由其頂端處影像左邊和右邊的夾角所決定的，其控制視野監(jiān)視器上顯示的影像圓周的大小。一旦視野大小發(fā)生變化則應(yīng)該顯示的圖像就會偏移或者顯示不出來，將會嚴(yán)重影響臨床醫(yī)生的操作，出現(xiàn)這種情況一般的原因有:

The field of view size of the endoscope is determined by the angle between the left and right sides of the image at its top, which controls the size of the image circumference displayed on the field of view monitor. Once the field of vision changes, the image that should be displayed will shift or not be displayed, which will seriously affect the clinician's operation. The general reasons for this are:

①目鏡損壞;

① The eyepiece is damaged;

②視頻適配器故障;

② Video adapter failure;

③CCD制式的改變等。

③ Change of CCD system, etc.

影像傳送失真或者有光暈現(xiàn)象

Distorted image transmission or halo

一般來說，影像在傳送過程中，纖維光纖的照相應(yīng)和透鏡系統(tǒng)的光圈大小有很大的關(guān)系，一旦其傳送過程之中某一環(huán)節(jié)出現(xiàn)問題，就會引起影像失真或是邊緣模糊、暗淡，同時出現(xiàn)光暈現(xiàn)象。此時如果增加光源的亮度能看清視野的邊緣，但中心部位會變得過于明亮刺眼，弓|起這種故障原因大部分是由于內(nèi)鏡中的透鏡出現(xiàn)故障。

Generally speaking, in the process of image transmission, the photography of fiber optic fiber should have a great relationship with the aperture size of the lens system. Once a problem occurs in a certain link in the transmission process, it will cause image distortion or blurring, dimming, and halo. At this time, if the brightness of the light source is increased, the edge of the field of vision can be seen clearly, but the central part will become too bright and dazzling. The cause of this failure is mostly due to the failure of the lens in the endoscope.

圖像模糊或過暗

The image is blurry or too dark

出現(xiàn)圖像模糊或者圖像過暗現(xiàn)象時，對于維修工程人員來說找出具體問題比較困難。一般出現(xiàn)此故障，主要有以嚇幾方面的原因:

When the image is blurry or too dark, it is difficult for maintenance engineers to find out the specific problems. This fault usually occurs for several reasons:

①光纖著色層與光纖老化，引起光源能量輸出降低;

① The colored layer of optical fiber and the aging of optical fiber cause the reduction of the energy output of the light source;

②光傳輸?shù)焦饫w時，光源內(nèi)燈泡未對準(zhǔn)光纖頭或光源內(nèi)其它光學(xué)部件未對準(zhǔn)而導(dǎo)致光輸出能量減少;

② When the light is transmitted to the optical fiber, the light bulb in the light source is not aligned with the optical fiber head or other optical components in the light source are not aligned, resulting in the reduction of light output energy;

③光纖內(nèi)可能有斷裂的纖維或纖維末端部有損壞;

③ There may be broken fibers in the optical fiber or the end of the fiber is damaged;

④內(nèi)鏡系統(tǒng)方面包括攝像頭、攝像線、適配器、適配環(huán)、圖像處理器以及顯示器等某-部件的故障。

④ The endoscopic system includes the failure of camera, camera line, adapter, adapter ring, image processor, display and other components.

如果要區(qū)分具體故障部位，一般要采用代替法加以區(qū)分。通常情況如果整幅圖像模糊，可能為內(nèi)鏡系統(tǒng)故障或光纖有未完全斷裂現(xiàn)象;若邊緣模糊表示內(nèi)鏡的纖維沒有足夠彎曲或光纖末端有毛糙現(xiàn)象。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://www.tukouzhao.cn咨詢看看吧！

If you want to distinguish specific fault parts, you should generally use the substitution method to distinguish them. In general, if the whole image is blurred, it may be the endoscopic system failure or incomplete fracture of optical fiber; If the edge is vague, it means that the tip fiber of the endoscope is not bent enough or the end of the fiber is rough.
