Common electrode configurations rau cov khoom siv nrog kev sib cais circuits
Muaj ntau ntau yam siv electrode configurations los yog circuit topologies:
Nrog"bipolar" Cov cuab yeej siv tam sim no tau siv rau tus neeg mob siv ob peb lub electrodes zoo sib xws. Piv txwv li, tshwj xeeb forceps, nrog ib tug tine txuas nrog ib tug ncej ntawm RF generator thiab lwm tine txuas nrog rau lwm tus ncej ntawm lub tshuab hluav taws xob. Thaum ib daim ntawm cov ntaub so ntswg tuav los ntawm forceps, RF hloov polarity hluav taws xob tam sim no oscillates ntawm ob lub forceps tines, cua sov cov ntaub so ntswg intervening los ntawm yav tas los piav synchronous oscillation ntawm intracellular ions.
Nyob rau hauv monopolar configuration tus neeg mob yog txuas mus rau lub dispersive electrode, ib tug kuj loj hlau phaj los yog ib tug saj zawg zog metalized yas ncoo uas txuas nrog lub RF generator los yog electrosurgical unit (ESU). Tus kws phais siv lub taw tes lossis cov hniav zoo li tus electrode hu ua" nquag electrode" txhawm rau tiv nrog cov ntaub so ntswg thiab ua kom cov ntaub so ntswg zoo ... vaporization, thiab nws cov kab propagation hu ua electrosurgical txiav, los yog kev sib xyaw ntawm desiccation thiab protein coagulation siv los kaw cov hlab ntsha rau lub hom phiaj ntawm Hemostasis. Cov hluav taws xob tam sim no oscillates nruab nrab ntawm lub active electrode thiab dispersive electrode nrog tag nrho cov neeg mob interposed ntawm ob. Txij li thaum lub concentration ntawm RF tam sim no txo nrog kev ncua deb ntawm lub active electrode tam sim no ceev ceev (quadratically) txo. Txij li thaum tus nqi ntawm cov ntaub so ntswg cua sov yog proportional rau lub square ntawm tam sim no ceev, cov cua kub tshwm sim nyob rau hauv ib tug heev localized cheeb tsam, tsuas yog nyob ze ntawm ib feem ntawm lub electrode, feem ntau yog lub ntsis, ze rau los yog nyob rau hauv kev sib cuag nrog lub hom phiaj cov ntaub so ntswg.
Ntawm qhov kawg nkaus xws li tus ntiv tes, muaj qhov txwv ntu ntu ntu kom tawg mus rau qhov tam sim no, qhov xwm txheej uas yuav ua rau muaj qhov ceev dua tam sim no thiab qee qhov cua sov thoob plaws qhov ntim ntawm qhov kawg.
