Txiab
Kev siv txiab endoscopically yuav tsum tau hloov me ntsis ntawm cov txheej txheem qhib. Cov cuab yeej yooj yim yog ib qho miniaturized, ntev tuav ntawm cov pa txiab thiab tuaj yeem ua ib zaug lossis ob zaug. Muaj qee yam tshwj xeeb ntawm txiab siv hauv kev phais endoscopic:
Insulated txiab
Cov no tso cai rau siv electrocautery los ntawm txiab. Txawm li cas los xij, thaum siv cov cuab yeej tsis siv pov tseg, electro coagulation siv cov hniav qhib ua rau blunting ntawm cov npoo. Electro coagulation siv cov txiab yog li txwv nyob rau hauv chav tsev no, thiab thaum nqa tawm tsuas yog siv nrog cov hniav kaw. Ntxuam dissection feem ntau yog ua nrog tus tuav ntawm tes kom nruj cov ntaub so ntswg. Yog tias qhov ntsuas no yog insulated ces tej hlab ntsha uas tau ntsib yuav tau yooj yim coagulated los ntawm tus grasper. Ib qho kev tsis zoo ntxiv cuam tshuam nrog electro coagulation nrog cov txiab tshwm sim los ntawm qhov ntev uas tsis yog rwb thaiv tsev yuav tsum tau ua kom haum rau cov hniav thiab pob khawm. Rau kev nyab xeeb kev xyaum no yuav tsum tau khaws cia nyob rau hauv saib thiab qhov no txwv qhov magnification muaj rau tus kws phais.
