sphincterotome la tuuri karo waxaa loo isticmaalaa cannulation endoscopic ee nidaamka ductal iyo sphincterotomy.
Qaabka: Sadexda lumen dhexroorka dibadda: 2.4mm dhererka tabo: 3mm/ 5mm/ 15mm Dhererka goynta:20mm/ 25mm/ 30mm Dhererka shaqada:2000mm
1. Dhexroorka
Dhexroorka sphincterotome guud ahaan waa 6Fr, qaybta sarena si tartiib tartiib ah ayaa loo dhimay ilaa 4-4.5Fr.Dhexroorka sphincterotome uma baahna fiiro gaar ah, laakiin waxaa lagu fahmi karaa in la isku daro dhexroorka sphincterotome iyo xoogga shaqada ee endoscope.Silig kale oo hage ma la mari karaa marka sphincterotome la dhigo.
2. Dhererka daabka
Dhererka daabku wuxuu u baahan yahay in fiiro gaar ah loo yeesho, guud ahaan 20-30 mm.Dhererka siliga hagaha ayaa go'aamiya xagasha qaansada ee mindida iyo dhererka xoogga inta lagu jiro jeexida.Sidaa darteed, inta uu sii dheeraado fiilada mindida, "xagalka" ee arc wuxuu u dhow yahay jihada anatomical ee dhuunta ganaca ee ganaca, taas oo laga yaabo inay sahlanaato in si guul leh loo dhexgeliyo.Isla mar ahaantaana, fiilooyinka mindida ee aadka u dheer waxay keeni karaan si xun u goynta sphincter iyo dhismayaasha ku hareeraysan, taasoo keentay dhibaatooyin halis ah sida dalool, sidaas darteed waxaa jira "middi caqli-gal ah" oo buuxisa baahiyaha badbaadada inta la buuxinayo dhererka.
3. Aqoonsiga sphincterotome
Aqoonsiga sphincterotome waa qayb aad muhiim u ah, inta badan si loo fududeeyo hawlwadeenku si fudud u fahmo oo u garto booska sphincterotome inta lagu jiro qalliinka qallafsan ee muhiimka ah iyo midka muhiimka ah, iyo in la muujiyo booska guud iyo booska la jeexay ee nabdoon.Guud ahaan, dhowr boos sida "bilow", "bilow", "barta dhexe" iyo "1/4" ee sphincterotome ayaa la calaamadeyn doonaa, kuwaas oo 1/4 ee ugu horreeya iyo barta dhexe ee mindi caqli-gal ah ay yihiin meelo ammaan ah goynta , inta badan la isticmaalo.Intaa waxaa dheer, calaamadeeyaha dhexe ee sphincterotome waa shucaac shucaac ah.Marka la eego kormeerka raajada, booska qaraabada ee sphincterotome ee sphincter si fiican ayaa loo fahmi karaa.Sidan oo kale, marka lagu daro dhererka mindida qaawan ee aragtida tooska ah, waxaa suurtagal ah in la ogaado in mindidu ay si badbaado leh u fulin karto jeexitaanka sphincter.Si kastaba ha ahaatee, shirkad kastaa waxay leedahay caadooyin calaamado kala duwan oo soo saarista calaamadaha, taas oo u baahan in la fahmo.
