Nyob rau hauv qhov kev txiav txim ntawm ultrasonic tsis, ob (los yog ntau tshaj ob) immiscible kua yog uniformly tov los ua ib tug dispersion system, thiab ib tug kua yog uniformly faib nyob rau hauv lwm yam kua los tsim ib tug emulsion. Ultrasonic emulsification kuj tau siv dav hauv ntau qhov chaw thiab ua lub luag haujlwm tseem ceeb.
Cov khoom siv ultrasonic emulsification feem ntau yog siv hauv kev lag luam tshuaj thiab kev lag luam txhua hnub los tsim ntau yam khoom emulsion, xws li tshuaj emulsion, tshuaj pleev ib ce thiab tawv khau polish. Cov khoom emulsified combustion ntawm cov roj (roj av, diesel, thiab lwm yam) thiab dej los yog pulverized thee kuj yuav ua tau los ntawm ultrasonic emulsification los txhim kho cov combustion nqi ntawm chav tsev roj.
Siv cov cuab yeej, los ntawm 3 - 5mm corneal lossis scleral incision, lub lens nucleus yog crushed los ntawm ultrasound kom nws chylous, thiab ces aspirated nrog rau lub cortex. Tom qab kev ua haujlwm, cov tshuaj ntsiav tom qab ntawm lub lens yog khaws cia, thiab cov khoom siv sab hauv qab ntawm lub lens tuaj yeem cog rau tib lub sijhawm.
Piv nrog rau kev phais mob cataract ib txwm muaj, phacoemulsification tau txais kev phais zoo dua thiab tau dhau los ua kev lees paub thoob ntiaj teb thiab txhim khu kev qha kev kho mob cataract.
