Daim ntawv thov ntawm ultrasonic emulsifier hauv kev kho mob teb
Ultrasonic emulsifier yog cov txheej txheem ntawm kev siv ultrasonic lub zog los sib xyaw ob (lossis ntau dua ob qho) cov kev daws teeb meem tsis xws luag los tsim lub kaw ua kom tawg, qhov twg ib qho kua tau sib faib rau lwm cov kua los ua emulsion.
Ultrasonic emulsifier yog tsim rau ntau yam kev lag luam:
1. Kev lag luam lom neeg: ntuj xim tshem tawm, polysaccharide extraction, alkaloid extraction, roj tawm.
2. Kev lag luam tshuaj lom neeg: ultrasonic gel liquefaction, resin defoaming.
3. Kev siv hauv tsev sim: kev sib tsoo ntawm tes, cov khoom tawg thiab cov khoom sib xyaw.
4. Kev lag luam kho dej: cov dej lim paug muaj qee zaum.
5. Kev lag luam ua khoom noj thiab tshuaj pleev ib ce: cawv yog cov ua kom zoo, thiab nano hais yog tsim tawm.
Hauv cov tshuaj, ultrasonic emulsifier yog siv los kho cov cataract. Ultrasonic emulsifier yog siv los tsoo lub lens nucleus nrog ultrasound dhau los ntawm 3-5 hli pob txha lossis phais nti ua kom nws chylo-zoo li, thiab tom qab ntawd nqus tawm ua ke nrog lub cortex. Tom qab lub sijhawm ua haujlwm, cov tshuaj pleev plooj posterior kom muaj txoj haujlwm khaws cia thiab posterior chamber intraocular lens tuaj yeem rub tawm tib lub sijhawm.
Kev phais kab mob cataract phacoemulsification Piv nrog kev phais mob tso tawm kom pom tseeb, phacoemulsification muaj cov txiaj ntsig zoo los ua kev phais thiab tau dhau los ua tus tseev tsim ntiaj teb txoj kev kho mob siab dua thiab txhim kho kev txhim kho cataract.
Cov yam ntxwv ntawm ultrasonic emulsifier rau cataract:
1. Zoo qhov muag pom rov qab thiab lub zog xa tom qab ua tiav.
2. Kev xav astigmatism tom qab yog me me, thiab nws yog qhov tsim nyog los kho lossis tswj astigmatism postoperative.
3. Lub sijhawm ua haujlwm yog luv, kev phais muaj tsawg, thiab qhov mob yog lub teeb; lub teeb puas uas yuav ua rau lub retina raug txo kom tsawg, thiab qhov ua kom zoo siab ntawm lub ntsej muag kuj tuaj yeem raug txiav txim siab nyob rau hauv cov xwm txheej.
4. Qhov kev phais mob yog me me thiab kev mob rov qab yog tom qab sai; cov tshuaj tom qab tshuaj yog qhov tsawg thiab lub sijhawm luv luv; txoj kev pheej hmoo ntawm kev raug mob thaum lub sijhawm ua haujlwm raug txo qis, thiab kev mob siab thiab nti nti ua kom tsawg.
5. Kev tswj phais neeg tau zoo dua, kev nyab xeeb yog txhim kho, thiab muaj teeb meem txo qis; nws yog qhov yooj yim kom muaj kev sib zog sib sib zog nqus hauv chav ua haujlwm thaum lub sijhawm ua haujlwm, thiab qhov tshwm sim ntawm posterior capsule raug mob thiab cortical seem raug txo qis; lub plhaw rau txoj kev kho qhov muag yog muaj kev nyab xeeb thiab txhim khu kev qha; qhov kev phais kaw tuaj yeem tswj tau qhov vitreous siab Zoo dua, nws muaj kev nyab xeeb dua rau qhov kev cuam tshuam ib zaug uas muaj teeb meem tshwm sim, thiab qhov ntsuas tau tswj tau zoo dua; qhov tshwm sim ntawm cov teeb meem xws li cystoid macular edema txo.
6. Tsis tas yuav tos tus cataract kom zoo ua ntej kev ua haujlwm yuav ua tau, uas zam txhua yam tsis raug thiab mob hauv cov txheej txheem tos ntev thiab txhim kho lub neej zoo.
