Disposable sphincterotome imagwiritsidwa ntchito popanga endoscopic cannulation ya ductal system ndi sphincterotomy.
Chitsanzo: Katatu lumen M'mimba mwake: 2.4mm Tip kutalika: 3mm / 5mm / 15mm Kudula kutalika: 20mm / 25mm / 30mm Ntchito kutalika: 2000mm
1. Diameter
Kutalika kwa sphincterotome nthawi zambiri kumakhala 6Fr, ndipo gawo lapamwamba limachepetsedwa mpaka 4-4.5Fr.Kutalika kwa sphincterotome sikufuna chidwi kwambiri, koma kumatha kumveka pophatikiza kukula kwa sphincterotome ndi mphamvu zogwirira ntchito za endoscope.Kodi waya wina wowongolera ungadutsedwe pomwe sphincterotome imayikidwa.
2. Kutalika kwa tsamba
Kutalika kwa tsamba kuyenera kuyang'aniridwa, nthawi zambiri 20-30 mm.Kutalika kwa waya wowongolera kumatsimikizira mbali ya arc mpeni ndi kutalika kwa mphamvu panthawi yodulidwa.Chifukwa chake, kutalikirapo kwa waya wa mpeni, kuyandikira kwa "angle" ya arc ndi njira ya anatomical ya pancreaticobiliary duct intubation, yomwe ingakhale yosavuta kuyiyika bwino.Panthawi imodzimodziyo, mawaya atali kwambiri a mpeni angayambitse kusokonezeka kwa sphincter ndi zozungulira zozungulira, zomwe zimabweretsa mavuto aakulu monga kuphulika, kotero pali "mpeni wanzeru" womwe umakwaniritsa zofunikira za chitetezo pamene ukukwaniritsa kutalika kwake.
3. Chizindikiritso cha sphincterotome
Chidziwitso cha sphincterotome ndi gawo lofunika kwambiri, makamaka kuti athandize wogwiritsa ntchito kumvetsetsa mosavuta ndi kuzindikira malo a sphincterotome panthawi yobisika komanso yofunikira yopangira opaleshoni, ndikuwonetsa malo omwe ali ofanana ndi malo otetezedwa.Nthawi zambiri, malo angapo monga "start", "start", "midpoint" ndi "1/4" ya sphincterotome adzalembedwa, pomwe 1/4 yoyamba ndi pakati pa mpeni wanzeru ndi malo otetezeka. kudula , kumagwiritsidwa ntchito kwambiri.Kuphatikiza apo, chizindikiro chapakati cha sphincterotome ndi radiopaque.Pansi pa kuwunika kwa X-ray, malo achibale a sphincterotome mu sphincter amatha kumveka bwino.Mwanjira imeneyi, kuphatikiza ndi kutalika kwa mpeni wowonekera pansi pa masomphenya achindunji, ndizotheka kudziwa ngati mpeniwo ukhoza kudulidwa bwino ndi sphincter.Komabe, kampani iliyonse ili ndi zizolowezi zofananira pakupanga ma logo, zomwe ziyenera kumveka.
