Daim ntawv thov ntawm kev phais kho hniav microscope hauv kev kho mob ntawm cov nqaij mos thiab cov kab mob periapical

Kev phais microscopesmuaj ob qhov zoo ntawm kev nthuav dav thiab teeb pom kev zoo, thiab tau siv rau hauv kev kho mob rau ntau tshaj li ib nrab xyoo pua, ua tiav qee qhov txiaj ntsig.Ua haujlwm microscopestau dav siv thiab tsim hauv pob ntseg phais hauv xyoo 1940 thiab hauv kev phais ophthalmic hauv xyoo 1960.

Hauv kev kho hniav,phais microscopestau siv rau kev kho hniav thiab kho kho kom zoo li qub thaum xyoo 1960s hauv Tebchaws Europe. Daim ntawv thov ntawmua haujlwm microscopesHauv endodontics tiag tiag pib hauv 1990s, thaum Italian kws tshawb fawb Pecora thawj zaug qhia txog kev sivkho hniav microscopeshauv kev phais endodontic.

Cov kws kho hniav ua tiav kev kho mob ntawm cov tawv nqaij thiab cov kab mob periapical raws li akev kho hniav microscope. Lub tshuab kuaj hniav kho hniav tuaj yeem nthuav dav hauv cheeb tsam hauv cheeb tsam, saib xyuas cov qauv zoo dua, thiab muab lub teeb pom kev txaus, tso cai rau cov kws kho hniav kom pom tseeb cov qauv ntawm cov kwj dej hauv paus thiab cov ntaub so ntswg periapical, thiab paub meej tias qhov chaw phais. Nws tsis tso siab rau kev xav thiab kev paub txog kev kho mob nkaus xwb, yog li txo qhov tsis paub tseeb ntawm kev kho mob thiab txhim kho kev kho mob zoo rau cov kab mob pulpal thiab periapical, ua rau qee cov hniav uas tsis tuaj yeem khaws cia los ntawm cov txheej txheem ib txwm muaj kom tau txais kev kho mob thiab khaws cia.

A kho hniav microscopeNws muaj lub teeb pom kev zoo, lub teeb pom kev zoo, lub teeb pom kev zoo, thiab lawv cov khoom siv. Lub tshuab magnification yog tsim los ntawm ib lub qhov muag, lub raj, lub hom phiaj lens, lub magnification adjuster, thiab lwm yam, uas sib sau ua ke kho qhov magnification.

Noj CORDERASOM-520-D Dental Surgical MicroscopeRaws li qhov piv txwv, qhov loj ntawm lub qhov muag yog li ntawm 10 × 15 ×, nrog rau kev siv dav dav ntawm 12.5X, thiab qhov ntev ntawm lub hom phiaj lens yog nyob rau hauv thaj tsam ntawm 200 ~ 500 hli. Lub magnification changer muaj ob hom kev khiav hauj lwm: hluav taws xob stepless hloov thiab phau ntawv nruam magnification hloov.

Lub illumination system ntawm lubphais microscopeyog muab los ntawm lub teeb pom kev zoo fiber ntau, uas muab cov teeb pom kev zoo sib xws rau kev pom thiab tsis tsim cov duab ntxoov ntxoo hauv thaj chaw phais. Siv cov lo ntsiab muag binocular, ob lub qhov muag tuaj yeem siv rau kev soj ntsuam, txo qhov qaug zog; Tau txais daim duab peb-dimensional. Ib txoj hauv kev los daws qhov teeb meem ntawm tus pab cuam yog txhawm rau txhim kho daim iav pab, uas tuaj yeem muab qhov pom tseeb zoo ib yam li tus kws phais mob, tab sis tus nqi ntawm equipping daim iav tus pab cuam yog qhov siab. Lwm txoj hauv kev yog txhawm rau txhim kho lub koob yees duab kaw lus ntawm lub tshuab tsom, txuas rau lub vijtsam zaub, thiab tso cai rau cov neeg pab saib ntawm qhov screen. Tag nrho cov txheej txheem phais kuj tseem tuaj yeem thaij duab lossis kaw los sau cov ntaub ntawv kho mob rau kev qhia lossis kev tshawb fawb tshawb fawb.

Thaum kho cov kab mob ntawm daim tawv nqaij thiab periapical,kho hniav microscopestuaj yeem siv rau kev tshawb nrhiav hauv paus kwj dej qhib, tshem tawm cov kwj dej calcified, kho cov hauv paus kwj dej phab ntsa perforations, tshuaj xyuas cov hauv paus kwj dej morphology thiab kev tu kom zoo, tshem tawm cov twj paj nruag tawg thiab cov kwj dej tawg, thiab ua haujlwm.microsurgicalcov txheej txheem rau kab mob periapical.

Piv nrog rau kev phais ib txwm muaj, qhov zoo ntawm microsurgery muaj xws li: qhov tseeb qhov chaw ntawm lub hauv paus apex; Kev phais kev phais ntawm cov pob txha ib txwm muaj qhov loj dua, feem ntau ntau dua lossis sib npaug li 10 hli, thaum microsurgical pob txha puas tsuaj muaj ntau yam me me, tsawg dua lossis sib npaug li 5 hli; Tom qab siv lub tshuab ntsuas, qhov chaw morphology ntawm cov hauv paus hniav tuaj yeem raug pom zoo, thiab lub kaum sab xis ntawm cov hauv paus txiav txoj kab nqes tsawg dua 10 °, thaum lub kaum sab xis ntawm cov cag ntoo txiav txoj kab nqes loj dua (45 °); Muaj peev xwm soj ntsuam cov isthmus ntawm cov kwj dej hauv paus ntawm qhov kawg ntawm cov hauv paus hniav; Yuav kom raug npaj thiab sau cov lus qhia hauv paus. Tsis tas li ntawd, nws muaj peev xwm nrhiav tau qhov qub anatomical landmarks ntawm lub hauv paus tawg qhov chaw thiab hauv paus kwj dej system. Cov txheej txheem phais tuaj yeem thaij duab lossis sau cov ntaub ntawv rau kev kho mob, kev qhia, lossis kev tshawb fawb tshawb fawb. Nws tuaj yeem suav tau tiaskho hniav microscopesmuaj txiaj ntsig zoo ntawm daim ntawv thov thiab kev cia siab hauv kev kuaj mob, kev kho mob, kev qhia, thiab kev tshawb fawb soj ntsuam ntawm cov kab mob ntawm cov hniav.
