Hauv kev kho mob endoscopy, cov lus qhia hlau tsis yog tsuas yog cov khoom siv yooj yim, tab sis kuj tseem yog ib lub nraub qaum ntawm kev ua tiav biliary thiab porcreatic kev cuam tshuam. Ntawm cov kev tsim ntau yam, cov lus qhia endoscoplic endoscoplic endoscopic tau tawm los ntawm cov txheej txheem xaiv ntau hauv ntau cov txheej txheem los ntawm kev muab cov txheej txheem sib xyaw ua ke, kev tswj hwm kev siv tau, thiab kev ua tau zoo ib yam.
Cov cuab yeej no yog engineered nrog kev sib npaug zoo ntawm kev hloov pauv thiab tawv ncauj, tuaj yeem muab kev taw qhia los ntawm kev ua kom pom tseeb los ntawm kev ua kom zoo nkauj lossis cov pa roj anatomy. Feem ntau cov stainless - steel lossis nitinol tseem ceeb, xaiv rau nws cov kev tswj hwm thiab kub nrog cov khoom siv hydroughilic lossis PTFE. Hydrophilic txheej quav tiv thaiv kev sib txhuam, tso cai kom muaj kev nruj me ntsis, thaum PTFE {{} coated sharets thaum tswj kev sib pauv. Cov lus qhia kev teeb tsa -}} Txawm cov tuabneeg tsw heev
Hauv ERCP kev xyaum, cov xaim qhia feem ntau tau sib tham hauv cov ntsiab lus ntawm kev ntev {} xaim thiab luv- xaim hlau. Ntev - cov kab hlau, feem ntau nyob ib ncig ntawm 450 cm nyob rau hauv ntev, tau ua ib txwm muaj kev tiv thaiv uas muaj ntau yam cuab yeej siv tau. Luv {{6- hlau tshuab, nyob ib ncig ntawm 260 8}- Tus neeg teb xov tooj kev tswj hwm, streambining niaj hnub ua ke. Txhua lub kaw lus muaj nws tus kheej kev kuaj mob, thiab cov kev paub txog Endoscorists thiab cov txheej txheem txaus thiab cov txheej txheem ntws.
Cov ntaub ntawv saib xyuas txiav txim siab txiav txim siab tsis yog tsuas yog qhov kev xaiv ntawm system, tab sis kuj yog txoj kab uas hla thiab cov qauv yas. A 0.025-inch hydrophilic-tipped wire may facilitate selective cannulation in challenging biliary anatomy, while a 0.035-inch stiff-shaft wire provides the stability required for stent deployment or stone extraction. Hauv cov txheej txheem nce siab xws li Eus-coj Biliary Plia, Nitinol-cov xov hlau feem ntau nyiam rau lawv cov kink tsis kam thiab kav ntev.
While disposable guide wires address many concerns related to cross-contamination and reprocessing, they are not without risks. Perforation tuaj yeem tshwm sim yog tias lub zog loj dhau lawm yog siv, tshwj xeeb yog nyob rau hauv lub xub ntiag ntawm nruj me ntsis. Hlau shearing, txawm tias tsis tshua muaj, yuav tshwm sim yog tias cov khoom siv tsis raug. Ceev faj cov txheej txheem, cov lus qhia fluoroscopic, thiab kev ua raws li cov txheej txheem kev coj ua zoo tshaj plaws tseem ceeb rau kev nyab xeeb.
Los ntawm kev ua tiav qhov pom, kev xaiv ntawm hydrophilic thiab ptfe {{}} coated hlau, yuav tsum tau coj los ntawm rooj plaub sib xyaw thiab cov tuam txhab ua ntej. Thaum hydrophilic thiab nitinol tsim yuav nqa cov nqi siab dua, lawv qhov kev cuam tshuam rau cov txheej txheem kev ua tiav thiab lub sijhawm ua haujlwm tau ua rau muaj txiaj ntsig ntev. Lub ntiaj teb txuas mus rau ib qho -} siv cov khoom siv tau txhaj tshuaj, qhia tias cov kav hlau tuaj yeem txuas ntxiv mus nthuav tawm lawv lub lag luam muaj.
Raws li Ercp cov tswv yim evolve thiab thov kom muaj kev kho mob loj tsis meej, cov txheej txheem endosity endoscopic yuav nyob rau cov txheej txheem tseem ceeb, kev nyab xeeb, thiab kev ua tau zoo. Rau cov kws kho mob, nkag siab txog kev tsim kho cov hlau thiab kev ua tau zoo yog tsis yog ib qho kev nthuav dav hauv kev xa cov txiaj ntsig ntawm tus neeg mob.
