ERCP Zvishandiso Katatu Lumen Imwechete Kushandisa Sphincterotome yeEndoscopic Kushandisa

1. Diameter
Iyo dhayamita ye sphincterotome inowanzo 6Fr, uye chikamu chepamusoro chinoderedzwa zvishoma nezvishoma kusvika 4-4.5Fr.Iyo dhayamita ye sphincterotome haidi kutariswa zvakanyanya, asi inogona kunzwisiswa nekubatanidza dhayamita ye sphincterotome uye kushanda nesimba kweiyo endoscope.Imwe tambo yegwara inogona kupfuudzwa nepo sphincterotome ichiiswa.
2. Kureba kwebanga
Kureba kweblade kunoda kutariswa, kazhinji 20-30 mm.Kureba kwewaya inotungamira kunogadzirisa arc angle yearc banga uye kureba kwesimba panguva yekucheka.Nokudaro, iyo yakareba waya yebanga, iyo inoswedera pedyo ne "angle" yearc kune anatomical direction ye pancreaticobiliary duct intubation, iyo inogona kuva nyore kupinza nekubudirira.Panguva imwecheteyo, waya dzebanga dzakarebesa dzinogona kukonzera kukanganisa kwe sphincter uye zvimiro zvakatenderedza, zvichikonzera matambudziko akakomba senge perforation, saka pane "smart banga" rinosangana nezvinodiwa zvekuchengetedza uchisangana nehurefu.
3. Sphincterotome identification
Kuzivikanwa kwe sphincterotome chidimbu chakakosha zvikuru, kunyanya kuita kuti mufambisi anzwisise zviri nyore uye aone nzvimbo ye sphincterotome panguva yekushanda kusinganzwisisiki uye kwakakosha, uye kuratidza nzvimbo yakajairika uye nzvimbo yakachengeteka yekucheka.Kazhinji, zvinzvimbo zvakati se "tanga", "tanga", "midpoint" uye "1/4" ye sphincterotome ichaiswa chiratidzo, iyo yekutanga 1/4 uye yepakati yebanga rakangwara inzvimbo dzakachengeteka. kucheka, kunyanya kushandiswa.Mukuwedzera, iyo midpoint marker ye sphincterotome inonzi radiopaque.Pasi pekutarisa kwe-X-ray, nzvimbo yakabatana ye sphincterotome mu sphincter inogona kunyatsonzwisiswa.Nenzira iyi, yakasanganiswa nehurefu hwebanga rakafumurwa pasi pechiratidzo chakananga, zvinokwanisika kuziva kana banga rinogona kuita sphincter incision zvakachengeteka.Nekudaro, kambani yega yega ine akasiyana logo maitiro mukugadzira logos, izvo zvinoda kunzwisiswa.
