Endoscope yog cov cuab yeej tshawb nrhiav uas suav nrog cov khoom siv kho qhov muag, ergonomics, cov tshuab precision, niaj hnub electronics, lej thiab software. ncaj qha saib cov kab mob uas tsis tuaj yeem pom los ntawm X-rays.Nws yog ib qho cuab yeej tseem ceeb rau kev kuaj xyuas sab hauv thiab kev phais thiab kev kho mob me me.
Txoj kev loj hlob ntawm endoscopes tau dhau los ntawm ntau tshaj 200 xyoo, thiab qhov ntxov tshaj plaws tuaj yeem taug qab mus rau xyoo 1806, German Philipp Bozzini tau tsim ib qho cuab yeej uas muaj tswm ciab ua lub teeb ci thiab lo ntsiab muag rau kev soj ntsuam cov qauv sab hauv ntawm tsiaj lub zais zis thiab lub qhov quav. Cov cuab yeej tsis siv nyob rau hauv tib neeg lub cev, Bozzini ushered nyob rau hauv lub era ntawm hard tube endoscope thiab yog li ntawd hailed li inventor ntawm endoscopes.
Hauv ze li ntawm 200 xyoo ntawm txoj kev loj hlob, endoscopes tau ua tiav plaub qhov kev txhim kho loj, los ntawmthawj zaug txhav raj endoscopes (1806-1932), semi nkhaus endoscopes (1932-1957) to fiber ntau endoscopes (tom qab xyoo 1957), thiab tam sim noelectronic endoscopes (tom qab xyoo 1983).
Xyoo 1806-1932:Thaum twgrigid tube endoscopesthawj zaug tau tshwm sim, lawv tau ncaj qha los ntawm hom, siv lub teeb kis tau tus mob thiab siv cov khoom siv hluav taws xob thermal rau illumination. Nws txoj kab uas hla yog tuab heev, lub teeb ci tsis txaus, thiab nws yog qhov ua rau kub hnyiab, ua rau nws nyuaj rau tus neeg kuaj mob, thiab nws daim ntawv thov ntau yog nqaim.
Xyoo 1932-1957:Semi nkhaus endoscopetau tshwm sim, tso cai rau ntau qhov kev ntsuam xyuas los ntawm qhov nkhaus pem hauv ntej kawg.Txawm li cas los xij, lawv tseem tau tawm tsam kom tsis txhob muaj qhov tsis zoo xws li cov kab tuab tuab, lub teeb tsis txaus, thiab lub teeb thermal hlawv.
Xyoo 1957-1983: Optical fibers pib siv nyob rau hauv endoscopic systems.Nws daim ntawv thov ua kom lub endoscope kom ua tiav kev khoov pub dawb thiab tuaj yeem siv dav hauv ntau yam kabmob, tso cai rau cov neeg kuaj xyuas kom yooj yim pom cov kab mob me me.Txawm li cas los xij, kev sib kis ntawm fiber ntau yog nquag tawg, nws cov duab magnification ntawm lub vijtsam zaub tsis meej txaus, thiab cov duab tshwm sim tsis yooj yim rau txuag.Nws tsuas yog rau tus neeg soj ntsuam saib xwb.
Tom qab xyoo 1983: Nrog rau innovation ntawm science thiab technology, qhov tshwm sim ntawmhluav taws xob endoscopestuaj yeem hais tias tau coj ib puag ncig tshiab ntawm kev hloov pauv.Lub pixels ntawm hluav taws xob endoscopes tau txhim kho tas li, thiab cov duab ntxim nyiam kuj muaj tseeb dua, dhau los ua ib qho ntawm cov khoom siv endoscopes tam sim no.
Qhov sib txawv loj tshaj plaws ntawm cov khoom siv hluav taws xob endoscopes thiab fiber ntau endoscopes yog tias cov khoom siv hluav taws xob endoscopes siv cov duab sensors es tsis txhob siv cov khoom siv hluav taws xob zoo tshaj plaws.Lub tshuab hluav taws xob endoscope CCD lossis CMOS duab sensor tuaj yeem tau txais lub teeb pom kev los ntawm lub ntsej muag daim npog ntsej muag hauv kab noj hniav, hloov lub teeb. teeb liab rau hauv hluav taws xob cov teeb liab, thiab tom qab ntawd khaws thiab ua cov teeb liab hluav taws xob los ntawm cov duab processor, thiab thaum kawg xa lawv mus rau cov duab sab nraud rau kev ua, uas tuaj yeem pom los ntawm cov kws kho mob thiab cov neeg mob hauv lub sijhawm.
Tom qab 2000: Ntau yam tshiab ntawm endoscopes thiab lawv cov ntawv txuas ntxiv tau tshwm sim, txuas ntxiv nthuav dav ntawm kev kuaj xyuas thiab kev siv cov endoscopes.Tshiab hom endoscopes tshwj xeeb yog sawv cev los ntawmkho mob wireless capsule endoscopes, thiab daim ntawv thov txuas ntxiv suav nrog ultrasound endoscopes, narrowband endoscopic technology, laser confocal microscopy, thiab lwm yam.
Nrog rau kev nruam ntej ntawm kev tshawb fawb thiab thev naus laus zis, qhov zoo ntawm cov duab endoscopic kuj tau dhau los ua qhov zoo tshaj plaws.Qhov kev siv tshuaj kho mob endoscopes hauv kev kho mob tau dhau los ua neeg nyiam, thiab niaj hnub hloov mus rauminiaturization,multifunctionality, thiabduab zoo.
