Izixhobo ze-ERCP I-Triple Lumen Ukusebenzisa enye i-Sphincterotome yokusetyenziswa kwe-Endoscopic
Izixhobo ze-ERCP I-Triple Lumen Ukusebenzisa enye i-Sphincterotome yokusetyenziswa kwe-Endoscopic
Isicelo
I-sphincterotome elahlayo isetyenziselwa i-endoscopic cannulation ye-ductal system kunye ne-sphincterotomy.
Umzekelo: Lumen kathathu Ubukhulu bangaphandle: 2.4mm ubude bengcebiso: 3mm / 5mm / 15mm Ukusika ubude: 20mm / 25mm / 30mm Ubude bokusebenza: 2000mm
IiParameters eziphambili zeSphincterotome ezilahlayo
1. Ububanzi
Ububanzi be-sphincterotome ngokuqhelekileyo yi-6Fr, kwaye inxalenye ye-apex iyancipha ngokuthe ngcembe ukuya kwi-4-4.5Fr.I-diameter ye-sphincterotome ayifuni ngqalelo enkulu, kodwa inokuqondwa ngokudibanisa ububanzi be-sphincterotome kunye ne-forceps yokusebenza ye-endoscope.Ngaba olunye ucingo lwesikhokelo lungagqithiswa ngelixa i-sphincterotome ibekwe.
2. Ubude be-blade
Ubude be-blade kufuneka buthathelwe ingqalelo, ngokubanzi 20-30 mm.Ubude bocingo lwesikhokelo bumisela i-angle ye-arc ye-arc knife kunye nobude bamandla ngexesha lokuqhawula.Ngoko ke, ixesha elide intambo yemela, isondele "i-angle" ye-arc kwi-anatomical direction ye-pancreaticobiliary duct intubation, enokuba lula ukuyifaka ngempumelelo.Kwangaxeshanye, iingcingo zemela ezinde kakhulu zinokubangela ukuchaneka kwe-sphincter kunye nezakhiwo ezingqongileyo, okukhokelela kwiingxaki ezinzulu ezifana nokugqobhoza, ngoko kukho "i-smart knife" ehlangabezana neemfuno zokhuseleko ngelixa idibana nobude.
3. Ukuchongwa kwe-sphincterotome
Ukuchongwa kwe-sphincterotome yinto ebaluleke kakhulu, ngokukodwa ukuququzelela umqhubi ukuba aqonde ngokulula kwaye achonge indawo ye-sphincterotome ngexesha lomsebenzi obuqilileyo kunye nobalulekileyo, kunye nokubonisa indawo eqhelekileyo kunye ne-incision ekhuselekileyo.Ngokuqhelekileyo, iindawo ezininzi ezifana ne "start", "start", "midpoint" kunye "1/4" ye-sphincterotome ziya kumakishwa, apho i-1/4 yokuqala kunye ne-midpoint ye-smart mela zikhuselekile ngokufanelekileyo. ukusika , isetyenziswa ngokuqhelekileyo.Ukongeza, i-midpoint marker ye-sphincterotome yi-radiopaque.Ngaphantsi kwe-X-ray iliso, indawo ehambelanayo ye-sphincterotome kwi-sphincter inokuqondwa kakuhle.Ngale ndlela, kudityaniswe nobude bemela eveziweyo phantsi kombono othe ngqo, kunokwenzeka ukwazi ukuba imela inokwenza ngokukhuselekileyo i-sphincter incision.Nangona kunjalo, inkampani nganye inemikhwa eyahlukeneyo yelogo kwimveliso yeelogo, ekufuneka iqondwe.
