I-Endoscope iyithuluzi lokubona elihlanganisa i-optics yendabuko, i-ergonomics, imishini enembayo, izinto zikagesi zesimanje, izibalo nesofthiwe. Ithembele osizweni lomthombo wokukhanya ukuze ingene emzimbeni womuntu ngemigodi yemvelo efana nembobo yomlomo noma izimbotshana ezincane ezenziwa ngokuhlinzwa, ukusiza odokotela. bheka ngokuqondile izilonda ezingenakho ukuboniswa ngama-X ray. Kuyithuluzi elibalulekile lokuhlolwa okuhle kwangaphakathi nokuhlinzwa kanye nokwelashwa okuncane kakhulu.
Ukuthuthukiswa kwama-endoscopes sekudlule iminyaka engaphezu kwengu-200, futhi eyokuqala ingalandelelwa emuva ku-1806, uPhilipp Bozzini waseJalimane wenza ithuluzi elihlanganisa amakhandlela njengomthombo wokukhanya namalensi okubuka ukwakheka kwangaphakathi kwesinye isinye kanye ne-rectum. Ithuluzi alizange lisetshenziswe emzimbeni womuntu, i-Bozzini yangenisa inkathi ye-tube endoscope eqinile ngakho-ke yadunyiswa njengomsunguli we-endoscopes.
Eminyakeni ecishe ibe ngama-200 yokuthuthuka, ama-endoscopes athuthuke kakhulu ngokwesakhiwo,amashubhu endoscopes okuqala aqinile (1806-1932), i-semi curved endoscopes (1932-1957) to i-fiber endoscopes (ngemuva kuka-1957),futhi manjeama-electronic endoscopes (ngemuva kuka-1983).
1806-1932:Niniama-tube endoscopes aqinilezaqala ukuvela, zaziqondile phakathi kohlobo, zisebenzisa imidiya yokudlulisa ukukhanya futhi zisebenzisa imithombo yokukhanya eshisayo ukuze zikhanyise. Ububanzi bayo bukhulu kakhulu, umthombo wokukhanya awenele, futhi ujwayele ukusha, okwenza kube nzima kumfundi ohlolwayo ukubekezelela, futhi uhla lwayo lokusebenza luncane.
1932-1957:I-endoscope egobile kancanekwavela, okuvumela ukuhlolwa okubanzi endaweni engaphambili egobile.Nokho, basazabalaza ukugwema izithiyo ezifana nobubanzi beshubhu elishubile, umthombo wokukhanya onganele, kanye nokushiswa kokukhanya okushisayo.
1957-1983: Imicu yokubona yaqala ukusetshenziswa ezinhlelweni ze-endoscopic.Uhlelo lwayo lwenza i-endoscope ifinyelele ukugoba mahhala futhi ingasetshenziswa kabanzi ezithweni ezihlukahlukene, okuvumela abahloli ukuthi babone kalula izilonda ezincane. Nokho, ukudluliswa kwe-fiber optical kujwayele ukuphuka, ukukhuliswa kwesithombe esikrinini sokubonisa akucacile ngokwanele, futhi isithombe esiwumphumela akulula ukusigcina.Esokuba umhloli kuphela asibuke.
Ngemva kuka-1983:Ngokusungulwa kwesayensi nobuchwepheshe, ukuvela kwei-electronic endoscopeskungathiwa ilethe umjikelezo omusha woguquko.Amaphikseli e-electronic endoscopes athuthuka njalo, futhi umphumela wesithombe nawo ubonakala ungokoqobo kakhulu, uba ngenye yama-endoscopes ajwayelekile okwamanje.
Umehluko omkhulu phakathi kwama-electronic endoscopes nama-fiber endoscopes ukuthi ama-electronic endoscopes asebenzisa izinzwa zesithombe esikhundleni se-original fibre imaging beam.I-electronic endoscope CCD noma inzwa yesithombe se-CMOS ingathola ukukhanya okuvela endaweni yemaski yobuso endaweni, iguqule ukukhanya. isignali kumasignali kagesi, bese ugcina futhi ucubungule lezi zimpawu zikagesi ngephrosesa yesithombe, futhi ekugcineni uzidlulisele ohlelweni lokubonisa isithombe sangaphandle ukuze lucutshungulwe, olungabukwa odokotela neziguli ngesikhathi sangempela.
Ngemva kuka-2000: Izinhlobo eziningi ezintsha zama-endoscope kanye nokusetshenziswa kwazo okunwetshiwe kwavela, okuqhubeka nokwandisa ububanzi bokuhlolwa kanye nokusetshenziswa kwama-endoscopes.Izinhlobo ezintsha zama-endoscope zimelelwa ikakhulukazii-endoscope ye-capsule engenantambo yezokwelapha,futhi izinhlelo zokusebenza ezinwetshiwe zihlanganisa ama-endoscopes e-ultrasound, ubuchwepheshe be-narrowband endoscopic, i-laser confocal microscopy, nokunye.
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ikhwalithi yezithombe ze-endoscopic nayo idlulele phambili.i-miniaturization,ukusebenza okuningi,futhiizinga eliphezulu lesithombe.
