Argon Plasma Coagulation

Argon plasma coagulation (APC), tseem hu ua argon riam, tau siv dav hauv kev qhib, endoscopic, thiab endoscopic phais nyob rau hauv xyoo tas los no vim nws cov txiaj ntsig zoo xws li ceev hemostasis, ntshav tsawg tsawg, txo oxidation, thiab eschar tsim. Nws txoj hauv kev ua haujlwm yog siv cov khoom siv hluav taws xob ntau zaus los ntawm cov khoom siv hluav taws xob los txhawb argon los tsim cov khoom siv hluav taws xob argon plasma los ua ib lub voj voog kaw, kom ua tiav cov txiaj ntsig ntawm superficial unipolar coagulation lossis cov ntaub so ntswg inactivation. Argon plasma coagulation yog unipolar uas tsis yog-hu rau coagulation hom.
Thaum lub high-frequency thiab high-voltage tso zis electrode ntawm argon plasma coagulation yog activated, argon roj yog sprayed tawm ntawm tus kov, thiab tam sim no ntawm lub electrode thiab lub hom phiaj cov ntaub so ntswg kis mus rau lub hom phiaj cov ntaub so ntswg los tsim zoo hemostatic los yog cov ntaub so ntswg inactivation. teebmeem. Cov txheej txheem dav hlau electrocoagulation hom, vim muaj qhov sib txawv ntawm huab cua ntawm cov electrode thiab los ntshav qhov txhab, nyuaj rau ionize, tsis tshua muaj ion concentration, thiab tsis zoo conductivity. Yog li ntawd, tam sim no kis mus rau lub hom phiaj cov ntaub so ntswg nyob rau hauv daim ntawv ntawm ib tug arc, uas ua rau tsis zoo coagulation nyhuv. Ntxiv mus, huab cua yog nplua nuj nyob rau hauv oxygen, tsis inert gases xws li argon. Yog li ntawd, ib txwm siv dav hlau electrocoagulation muaj pa luam yeeb loj, cov ntaub so ntswg yooj yim carbonization, thiab muaj ntxhiab tsw ntxhiab. Hauv kev sib piv, argon plasma coagulation, raws li hom tshwj xeeb ntawm kev ua tiav electrocoagulation siv inert roj argon ionization, muaj cov txiaj ntsig zoo.
