Peb puas tau rov ua dua Endoscopic Biopsy Forceps txaus?

Kev ntxuav ntawm endoscopic biopsy forceps yog theem tseem ceeb tshaj plaws ntawm txoj kev tua kab mob, vim nws muaj nyob rau ntawm kev tshem tawm tag nrho cov khoom siv organic. Txawm li cas los xij, qhov zoo li tus kauv thiab lawv qhov kawg ntawm lub khob ua rau nyuaj rau kev tsis txaus thiab ntxuav cov forceps. Lub hom phiaj: 1) txhawm rau txheeb xyuas qhov kev tshem tawm ntawm cov khoom seem ntawm cov forceps los ntawm peb txoj kev sib txawv; 2) Txheeb xyuas tus nqi ntawm txhua txoj kev. Cov txheej txheem: Peb randomized txoj kev tshawb no suav nrog 60 biopsy forceps siv niaj hnub rau kev kuaj urease, ntawm Endoscopic Unit ntawm University of Sao Paulo. Peb ua raws li cov txheej txheem: kev tshem tawm forceps thiab ntxuav nrog gauze; immersion nyob rau hauv 0.5%-enzymatic tov nyob rau hauv 20 feeb; muaj zog mechanical ntxuav thiab yaug nrog dej. Tom qab ntawd, cov forceps tau muab cais ua peb pawg, xws li: pawg a. 20 forceps - tsis muaj kev ntxuav ntxiv; pab b. 20 forceps - immersion nyob rau hauv 3% hydrogen peroxide tov (20 feeb); pab pawg c. 20 forceps - ultrasound ntxuav nrog enzymatic detergent. Nyob rau theem ob, cov forceps raug xa mus rau kev soj ntsuam los ntawm kev siv lub lens magnifying (20 zaug), tsuas yog ib tus neeg soj ntsuam, uas tsis paub txog kev tu cov txheej txheem siv, muab faib rau hauv: txoj kev tu kom tsim nyog: tsis muaj cov khoom siv organic; Txoj kev tsis tsim nyog: muaj cov khoom siv organic (secretion los yog ntshav / cov ntaub so ntswg). Tom qab ntawd, tag nrho cov forceps tau rov ua dua tshiab nrog cov tshuaj enzymatic thiab sterilized nyob rau hauv ethylene oxide. Cov txiaj ntsig: Peb tuaj yeem txheeb xyuas ob hom: 1. ntshav lossis cov ntaub so ntswg (adhered rau lub khob); 2. whiteish secretion (los ntawm lub cev ntawm forceps). Peb kuj tuaj yeem soj ntsuam tias cov forceps xa mus rau kev ntxuav nrog peroxidase nthuav tawm cov xim ci dua thiab sib dua, piv rau cov uas tau kho nrog cov tshuaj detergent nkaus xwb. Txoj kev ntxuav tau suav tias tsim nyog hauv 20% (4/20) hauv pawg a; 70% (14/20) hauv pawg b, thiab 55% (11/20) hauv pawg c. Yog li, peroxidase thiab kev ntxuav ultrasound tau nthuav tawm cov txiaj ntsig zoo tshaj plaws thaum muab piv rau cov tshuaj ntxuav tes enzymatic nkaus xwb; p <0.01 thiab p=0.014, raws. Tus nqi tshuaj tua kab mob rau pab pawg a yog U$14.00, pab pawg b U$64.50 thiab pab pawg c U$46.20. Cov lus xaus: 1. Lub peroxidase ntxiv kev ua tau zoo ntawm txoj kev desinfection; 2. Txawm hais tias nthuav tawm tus nqi zoo dua thaum muab piv rau kev ntxuav ultrasound, nws yog ib txoj hauv kev nyab xeeb thiab muaj txiaj ntsig, vim nws kuj muaj cov kab mob bactericidal, fungicidal, viruscidal thiab sporicidal zoo.
