Nrog rau txoj kev loj hlob ntawm kev tshawb fawb niaj hnub thiab thev naus laus zis, endoscopes tau ua tiav kev hloov pauv, suav nrog cov fibers optical. Xyoo 1963, Nyiv pib tsim cov fiber ntau optic endoscopes, thiab xyoo 1964, lub tshuab biopsy rau fiber ntau optic endoscopes tau tsim tiav. Qhov tshwj xeeb biopsy forceps tso cai rau cov qauv pathological uas tsim nyog nrog kev pheej hmoo tsawg. Xyoo 1965, fiber ntau optic colonoscope tau tsim, nthuav dav qhov kev kuaj mob rau cov kab mob hauv plab. Kev tshawb fawb pib xyoo 1967 ntawm kev nthuav dav fiber ntau optic endoscopes los soj ntsuam cov kab mob feeb. Fiber optic endoscopes kuj tseem siv tau rau hauv vivo kuaj kuaj, xws li ntsuas lub cev kub, siab, txav chaw, spectral absorption, thiab lwm yam ntaub ntawv.
Xyoo 1973, laser thev naus laus zis tau siv rau kev kho mob endoscopic thiab maj mam dhau los ua ib txoj hauv kev kho mob plab hnyuv endoscopically. Nyob rau hauv 1981, endoscopic ultrasound tshuab tau ntse tsim. Qhov kev txhim kho tshiab no, ua ke nrog cov thev naus laus zis ultrasound nrog endoscopy, ua kom qhov tseeb ntawm kev kuaj mob tau zoo.
Thaum lub Kaum Ib Hlis 2002, lub ntiaj teb thawj "siab-txhais endoscope system" tau yug los, hloov pauv lub tswvyim ntawm endoscopy. Nws suav nrog kev txiav ntau tshaj -ntug imaging thev naus laus zis, muab cov duab meej uas ua rau nws tuaj yeem kuaj pom qhov mob me me. Kev tshwm sim ntawm niaj hnub video endoscopes, hluav taws xob endoscopes, thiab ultrasound endoscopes tau coj mus rau lub sijhawm tshiab ntawm kev kho mob endoscopy niaj hnub, hloov ntawm lub sijhawm ntawm kev kuaj thiab kuaj mob mus rau lub sijhawm kho thiab phais.
