ERCP Instruments Triple Lumen Ib Leeg Siv Sphincterotome rau Endoscopic Siv
ERCP Instruments Triple Lumen Ib Leeg Siv Sphincterotome rau Endoscopic Siv
Daim ntawv thov
Disposable sphincterotome yog siv rau endoscopic cannulation ntawm lub ductal system thiab rau sphincterotomy.
Qauv: Triple lumen Sab nraud txoj kab uas hla: 2.4mm Lub taub ntev: 3mm / 5mm / 15mm Txiav ntev: 20mm / 25mm / 30mm Ua haujlwm ntev: 2000mm
Lub ntsiab Parameters ntawm Disposable Sphincterotome
1. Txoj kab uas hla
Txoj kab uas hla ntawm sphincterotome feem ntau yog 6Fr, thiab qhov apex yog maj mam txo mus rau 4-4.5Fr. Txoj kab uas hla ntawm sphincterotome tsis xav tau kev saib xyuas ntau, tab sis nws tuaj yeem nkag siab los ntawm kev sib txuas ntawm txoj kab uas hla ntawm sphincterotome thiab kev ua haujlwm forceps ntawm endoscope. Puas muaj lwm txoj kev qhia xaim hla thaum lub sphincterotome muab tso rau.
2. Qhov ntev ntawm cov hniav
Qhov ntev ntawm cov hniav yuav tsum tau them sai sai rau, feem ntau 20-30 mm. Qhov ntev ntawm cov ntawv qhia hlau txiav txim siab lub kaum sab xis ntawm lub riam arc thiab qhov ntev ntawm qhov quab yuam thaum lub sijhawm txiav. Yog li ntawd, ntev riam hlau, qhov ze ntawm "lub kaum sab xis" ntawm lub arc yog mus rau lub anatomical kev taw qhia ntawm pancreaticobiliary duct intubation, uas tej zaum yuav yooj yim rau intubate ntse. Nyob rau tib lub sijhawm, cov riam ntev dhau lawm yuav ua rau tsis zoo ntawm cov sphincter thiab cov qauv nyob ib puag ncig, ua rau muaj teeb meem loj xws li perforation, yog li muaj "smart riam" uas ua tau raws li qhov xav tau ntawm kev nyab xeeb thaum ntsib qhov ntev.
3. Kev txheeb xyuas Sphincterotome
Kev txheeb xyuas ntawm sphincterotome yog ib qho tseem ceeb heev, feem ntau yog los pab tus neeg teb xov tooj kom nkag siab tau yooj yim thiab txheeb xyuas txoj hauj lwm ntawm sphincterotome thaum lub sij hawm hloov maj mam thiab tseem ceeb incision, thiab qhia txog txoj hauj lwm thiab kev nyab xeeb incision txoj hauj lwm. Feem ntau hais lus, ob peb txoj haujlwm xws li "pib", "pib", "midpoint" thiab "1/4" ntawm sphincterotome yuav raug cim, ntawm cov thawj 1/4 thiab nruab nrab ntawm cov riam ntse yog txoj haujlwm zoo rau txiav, feem ntau siv. Tsis tas li ntawd, lub midpoint marker ntawm sphincterotome yog radiopaque. Raws li kev soj ntsuam X-ray, qhov txheeb ze ntawm sphincterotome hauv sphincter tuaj yeem nkag siab zoo. Nyob rau hauv txoj kev no, ua ke nrog qhov ntev ntawm cov riam raug nyob rau hauv lub zeem muag ncaj qha, nws muaj peev xwm paub seb rab riam puas tuaj yeem ua rau sphincter incision. Txawm li cas los xij, txhua lub tuam txhab muaj cov cwj pwm sib txawv hauv kev tsim cov logos, uas yuav tsum tau nkag siab.
