Noj CORDERASOM-520-D Kev Ntsuas Hniav NtsuasUa piv txwv, kev tshaj tawm ntawm lub qhov muag daj ntawm 10 × rau 15 ×, nrog ib qho ntev siv ntawm lub hom phiaj lens yog nyob rau hauv ntau 200 ~ 500 hli. Lub zog ua haujlwm muaj zog muaj ob hom kev ua haujlwm: Electric Stepress Haum thiab Kev Tuav Nruag Nrawm kev hloov kho tshiab.

Lub cev ntawm lubKev phais mobyog muab los ntawm cov fiber ntau lub teeb pom kev zoo, uas muab lub teeb pom kev kaj nrig rau kev saib thiab tsis tsim cov duab ntxoo hauv thaj chaw phais. Siv cov iav lo ntsiab muag, ob lub qhov muag tuaj yeem siv rau kev soj ntsuam, txo kev qaug zog; Tau txais ib qho peb-sab nraud ua kua. Ib txoj kev los daws cov teeb meem pab yog muab cov kev pab pab, uas tuaj yeem muab qhov pom tseeb ntawm tus kws phais neeg, tab sis tus nqi ntawm equipping ib lub tsom iav pab yog qhov tseem ceeb. Lwm txoj hauv kev yog txhawm rau nruab ib lub koob yees duab lub koob yees duab ntawm lub tshuab tsom, txuas nws rau cov tshuaj pleev zaub mov, thiab cia cov neeg pabcuam saib xyuas lub vijtsam. Tag nrho cov txheej txheem kev phais mob kuj tseem tuaj yeem yees duab lossis sau tseg los sau cov ntaub ntawv kho mob rau kev qhia lossis tshawb fawb.

Piv nrog kev phais ib txwm, qhov zoo ntawm microsurgy xws li: precise muab tso tawm ntawm lub hauv paus apex; Kev phais cov pob txha muaj ntau dua, feem ntau ntau dua lossis sib npaug lossis sib npaug ntawm cov pob txha me me, tsawg dua lossis sib luag rau 5 hli; Tom qab siv lub tshuab tsom, lub hauv paus hniav nto corphology ntawm cov nqaj hlau tuaj yeem pom kom raug, thiab lub kaum sab xis ntawm lub hauv paus ntawm cov kab nqes yog loj dua (45 °); Muaj peev xwm saib cov ownmus ntawm cov hauv paus canals ntawm lub ntsis ntawm lub hauv paus; Muaj peev xwm npaj kom raug thiab sau cov lus qhia cag. Ib qho ntxiv, nws tuaj yeem nrhiav qhov qub anatomical thaj av ntawm lub hauv paus boacture site thiab cov kwj dej hauv paus dej. Tus txheej txheem phais tuaj yeem yees duab lossis kaw cia kom sau cov ntaub ntawv rau cov kws khomob, kev qhia, lossis kev tshawb fawb tshawb fawb.
