Endoscopy yog ib qho kev tsim kho tshiab tshaj plaws hauv cov tshuaj niaj hnub no - ua rau cov kws kho mob pom lub cev sab hauv yam tsis muaj kev phais qhib. Niaj hnub no, nruj endoscopes yog cov cuab yeej txheem hauv ENT phais, urology, gynecology, thiab neurosurgery, nrog cov txheej txheem siab zoo xws li cov kab mob txha caj qaum uas tsim cov pob txha ntawm Kev Ua Haujlwm Endoscopic Sinus Surgery (FESS).
Tab sis qhov no technology tsis tshwm sim thaum hmo ntuj. Txoj kev loj hlob ntawm endoscopy spans ze li ntawm ob centuries, nce los ntawm candlelit soj ntsuam raj mus rau siab -definition rod lens optical systems muaj peev xwm daws tau zoo mucosal nthuav dav nyob rau hauv lub sij hawm. Kev nkag siab txog qhov kev hloov pauv no muab cov ntsiab lus tseem ceeb rau cov kws kho mob, kws kho tsheb, thiab cov kws tsim khoom siv kho mob ua haujlwm hauv daim teb no niaj hnub no.
1. Lub Ntsiab Tseem Ceeb: Bozzini thiab Lichtleiter (1795)
Keeb kwm ntawm endoscopy pib nyob rau hauv lub xyoo pua 18th, thaum tus kws kho mob German Philipp Bozzini tau qhia txog qhov dav dav suav tias yog thawj cov cuab yeej tsim los rau kev pom sab hauv. Nws cov cuab yeej, Lichtleiter (lub ntsiab lus "lub teeb hluav taws xob"), siv lub teeb taws teeb pom kev los ntawm cov iav los ua kom pom cov kab noj hniav ntawm lub cev - nrog rau cov zis, qhov quav, thiab qhov ntswg.
Lub Lichtleiter yeej tsis tau siv hauv kev kho mob ntawm qhov dav, thiab Bozzini ntsib kev thuam los ntawm kws kho mob kws kho mob ntawm Vienna rau kev sim rau tib neeg. Txawm li cas los xij, nws lub tswv yim - coj teeb pom kev zoo rau hauv lub cev kom ua kom pom kev kuaj pom - tsim lub hauv paus ntsiab lus uas txhua qhov kev txhim kho endoscopic tom ntej yuav raug tsim.

2. Thawj Cov Txheej Txheem Endoscopic (1835–1853)
Kev vam meej tau nrawm dua nyob rau nruab nrab -19th caug xyoo. Xyoo 1835, tus kws kho mob Fab Kis Fab Kis Antoine Jean Desormeaux tau tsim cov cuab yeej siv tau ntau dua uas siv lub teeb roj kerosene los ua lub teeb ci, nrog rau lub teeb tsom iav thiab lo ntsiab muag rau kev teeb pom kev zoo. Los ntawm 1853, nws tau ua tiav siv cov cuab yeej no los tshuaj xyuas lub zais zis - qhov kev ua tiav uas tau ua rau nws lees paub tias yog ib qho ntawm cov qauv tsim ntawm kev kho mob endoscopy.
Txawm hais tias qhov kev vam meej no, endoscopes thaum ntxov muaj cov kev txwv tseem ceeb uas txwv tsis pub lawv cov txiaj ntsig kho mob:
- Lub teeb qhov chaw tsis muaj zog, tsis ruaj khov, thiab tsim cov cua sov uas ua rau muaj kev pheej hmoo ntawm cov nqaij mos
- Qhov chaw saib yog nqaim thiab distorted
- Rigid hlau ntxig raj ua rau cov neeg mob tsis xis nyob
- Sterilization tsis sib haum, ua rau muaj kev pheej hmoo kis mob
- Diagnostic raug raug txwv los ntawm cov duab tsis zoo
Raws li qhov tshwm sim, qhov endoscopy thaum ntxov tau raug txwv ntau rau kev kuaj mob ntawm lub zais zis thiab qhov quav, thiab txawm tias nyob rau hauv cov ntawv thov no, nws cov nqi kho mob tau qis dua piv rau qhov yuav ua raws li.
3. Lub Sijhawm Hloov Pauv: Lub Teeb Hluav Taws Xob thiab Txhim Kho Optics (1870s-1950s)
Lub invention ntawm hluav taws xob incandescent noob nyob rau hauv 1870s hloov endoscope tsim. Thawj thawj zaug, qhov chaw ruaj khov, tswj tau lub teeb ci tuaj yeem ua rau me me thiab nkag mus rau hauv lub cev - tshem tawm cov cua sov txaus ntshai thiab tsis ruaj khov ntawm qhib - nplaim taws.
Tshaj li kaum xyoo tom ntej, endoscope tsim maj mam txhim kho:
- Miniaturized hluav taws xob teeb tau muab tso rau hauv qhov kawg ntawm cov twj paj nruag
- Lens systems tau ua kom zoo dua los txhim kho cov duab pom tseeb thiab thaj chaw pom
- Cov cuab yeej diameters tau nce zuj zus
- Cov ntawv thov anatomical tshiab tau tshawb xyuas, suav nrog kev kuaj mob gastroscopy thiab bronchoscopy
Txawm li cas los xij, qhov tseem ceeb kho qhov muag txwv tseem nyob. Pa lo ntsiab muag-raws li relay systems - uas kis tau cov duab los ntawm ib tug series ntawm cov me me lo ntsiab muag sib cais los ntawm cov huab cua qhov chaw - raug kev txom nyem los ntawm ntau yam teeb pom kev zoo, tsis muaj teeb meem, thiab geometric distortion. Cov kev txwv no tau cuam tshuam qhov kev soj ntsuam kev ua tau zoo ntawm cov endoscopes nruj thiab tsav kev tshawb nrhiav rau qhov sib txawv ntawm qhov kho qhov muag.
4. Hopkins Rod Lens Revolution (1960s)
Qhov tseem ceeb tshaj plaws ib qho kev nce qib hauv cov keeb kwm endoscope nruj tuaj nyob rau xyoo 1960, thaum tus kws kho mob Askiv Askiv Harold Hopkins tau tsim lub pas nrig lens optical system - tus qauv tsim uas hloov pauv endoscope kev ua tau zoo thiab tseem yog lub hauv paus ntawm niaj hnub nruj endoscopes rau niaj hnub no.
Kev sib piv daim duab ntawm Hopkins rod lens system piv rau cov pa lo ntsiab muag relay hauv nruj endoscopes
Hopkins 'kev pom yog los hloov cov qauv tsim. Tsis yog siv cov lo ntsiab muag me me sib cais los ntawm qhov chaw huab cua ntev, lub pas nrig lens system siv cov iav cylindrical ntev sib cais los ntawm qhov chaw cua luv. Qhov no zoo li yooj yim inversion ua rau kev txhim kho kho qhov muag:
- Lub teeb kis tau tus mobnce los ntawm ib qho tseem ceeb ntawm kwv yees li 80 piv rau cov qauv siv lo ntsiab muag
- Kev daws teeb meemtxhim kho qhov tseem ceeb, ua kom pom kev zoo ntawm kev nthuav dav anatomical
- Xim fidelitytau markedly zoo dua, nrog nruab nrab, raug xim rendering
- Distortiontau txo qis, ua cov duab geometrically tseeb
Hopkins pib nyuaj rau kev lag luam nws qhov kev tsim, tab sis tom qab koom tes nrog Karl Storz nyob rau xyoo 1960s, tus pas nrig lens endoscope tau nkag mus rau kev siv tshuaj kho mob thiab tau dhau los ua cov thev naus laus zis tseem ceeb hauv kev kho endoscopy.
