Izinhlobo zamakhamera we-Electronic Endoscope

I-endoscope ye-elekthronikhi amakhamera ingahlukaniswa kakhulu ngezigaba ezilandelayo ngokususelwa kuzimo zokusetshenziswa kobuchwepheshe:

Ikhamera ye-CCD Electronic Endoscope: Isebenzisa i-charge-coupled device (CCD) njengenzwa yesithombe. Izinzwa ze-CCD zinezici zokulungiswa, ukuzwela ukukhanya okuhle kakhulu, nomsindo ophansi, ongathwebula izithombe ezinemininingwane ecebile kanye nekhwalithi yesithombe ecacile. Ifanele ukuxilongwa kwezokwelapha ngekhwalithi ephezulu kakhulu yesithombe, njenge-gastroscopy, lapho odokotela bengakwazi ukubona ngokunembile izilonda ezicashile ze-mucosa yamathumbu. Kodwa-ke, izindleko zokukhiqiza zezinzwa ze-CCD ziphakeme kakhulu, futhi ubukhulu bukhulu ngokuqhathaniswa, okuholela ezindleko eziphezulu zemishini kanye nokuguquguquka okulinganiselwe.

Ikhamera ye-CMOS Electronic Endoscope: Isebenzisa i-metal-oxide-semiconductor ehambisanayo (i-CMOS njengenzwa yesithombe. Izinzwa ze-CMOS zinezinzuzo zezindleko eziphansi, ukusetshenziswa kwamandla okuphansi, nokuhlanganiswa okuphezulu. Eminyakeni yamuva nje, kube nokuthuthuka okuphawulekayo kwekhwalithi yesithombe, engahlangabezana nezidingo eziningi zokuhlolwa okujwayelekile, njengokuhlolwa kwangaphakathi kwamapayipi ezimboni, akwazi ukudlulisa isivinini sangempela, futhi adlulise izithombe ezicacile ezifanele ngesikhathi sangempela. izinhlelo zokusebenza zokuqapha ngesikhathi sangempela Nokho, ezindaweni ezinokukhanya okuphansi, ikhwalithi yayo yokuthwebula ingase ingabi yinhle njengezinzwa ze-CCD.

Ikhamera ye-Fiber Optic Endoscope: Idlulisa amasignali esithombe ngenqwaba yefiber optic. Ingaphambili liyingxenye encane eqinile, futhi ingxenye yokufaka yakhiwa inqwaba ye-fiber optic ethambile egobekayo, elungele ukujula ezingxenyeni ezihlukumezayo zomzimba womuntu noma amapayipi ayinkimbinkimbi emishini yezimboni. Ingakwazi ukubona ngokuqondile isimo sangaphakathi ngeso, noma ingaxhunywa kudivayisi yokutholwa kwesithombe ukuze irekhode izithombe. Ivame ukusetshenziswa ku-bronchoscopy yamaphaphu engafinyelela ku-bronchi encane ekujuleni kwamaphaphu futhi inikeze isisekelo sokuxilongwa kwezifo zesistimu yokuphefumula. Izinzuzo zayo zithambile futhi ziguquguqukayo, zingagoba futhi zingafinyelela izingxenye eziyinkimbinkimbi; okubi ukuthi ukulungiswa kwesithombe kuphansi, futhi inqwaba ye-fiber optic ijwayele ukulimala.

Ikhamera ye-Video Electronic Endoscope: Isebenzisa amadivaysi ezithombe e-CCD anombala wedijithali noma we-CMOS, aguqula amasiginali wesithombe abe amasiginali wevidiyo ukuze akhishwe, futhi afaniswa nezikhungo zokucubungula izithombe namamonitha. Isithombe sicacile futhi sinokulungiswa okuphezulu, futhi singahlinzeka ngemisebenzi ehlukahlukene yokuthuthukisa nokucutshungulwa kwesithombe, okuyinto elula ukuthi odokotela bayibheke futhi bayihlaziye. Isetshenziswa kabanzi ekuhlinzeni kwe-laparoscopic emkhakheni wezokwelapha, ihlinzeka ngombono ocacile wokuhlinzwa kokuhlinzwa; emkhakheni wezimboni, isetshenziselwa ukuhlola kwangaphakathi imishini emikhulu, ukusiza ochwepheshe bathole amaphuzu anephutha. Kulula ukuyisebenzisa futhi inezinhlobonhlobo zezinhlelo zokusebenza, kodwa izindleko zemishini ziphakeme kakhulu.

Ikhamera ye-Micro Electronic Endoscope: Inevolumu encane futhi ingangena ezindaweni eziwumngcingo. Isibonelo, ikhamera encane ye-Medigus SCOUTCAM 1.2 enobubanzi obungu-1.2 kuphela ingahlanganiswa kumadivayisi ahlukahlukene, afanele ukuhlolwa kwangaphakathi kwamapayipi amancane nezingxenye ezinembayo, kanye nokuhlola izingxenye ezithile ezincane zomzimba womuntu, njengokubheka izilonda ezincane endlebeni nasemphinjeni. Ukulungiswa kanye nenkundla yokubuka kungase kube nomkhawulo, futhi kuyadingeka ukukhetha ngokuya ngesimo sohlelo oluthile.
