Electrosurgery yog ib txoj kev siv dav siv los txiav, coagulate, thiab tswj cov ntshav thaum lub sijhawm phais. Kev siv cov cuab yeej electrocautery tau hloov kho cov txheej txheem phais, ua rau lawv muaj kev nyab xeeb dua, ua haujlwm tau zoo thiab meej dua. Ob hom kev siv electrosurgical units (ESU) feem ntau yog bipolar thiab monopolar.
Cov twj siv hluav taws xob bipolar yog tsim los nrog ob lub electrodes uas tau muab tso ua ke, cia cov hluav taws xob hla tsuas yog nruab nrab ntawm lawv. Tam sim no tsis ntws los ntawm tus neeg mob lub cev, thiab yog li nws muaj kev nyab xeeb dua thiab ua rau cov nqaij mos puas tsawg. Bipolar electrosurgery feem ntau yog siv rau cov txheej txheem phais me me uas yuav tsum tau muaj qib siab, xws li neurosurgery thiab ophthalmic phais. Bipolar electrosurgery kuj pom zoo rau kev phais laparoscopic vim nws tsis txhob cuam tshuam hluav taws xob nrog cov qauv uas nyob ib sab.
Ntawm qhov tod tes, cov twj siv hluav taws xob monopolar muaj cov khoom siv hluav taws xob thiab cov hluav taws xob rov qab. Lub active electrode yog siv los xa cov hluav taws xob tam sim no mus rau cov ntaub so ntswg thaum lub electrode rov qab nqa cov tam sim no tawm ntawm tus neeg mob lub cev los ntawm ib tug grounding ncoo. Monopolar electrosurgery yog ntau yam tshaj li bipolar electrosurgery thiab tuaj yeem siv rau ntau yam kev phais, nrog rau kev txiav, coagulation thiab cov ntaub so ntswg fusion. Monopolar ESU tseem tuaj yeem tsim cov ntaub so ntswg sib sib zog nqus, ua rau nws tsim nyog rau kev phais loj dua.
Ob leeg bipolar thiab monopolar ESUs muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Bipolar electrosurgery yog qhov tseeb dua, muaj kev nyab xeeb dua thiab ua rau muaj kev puas tsuaj tsawg rau cov ntaub so ntswg ib puag ncig tab sis nws tsis haum rau txhua txoj kev phais. Monopolar electrosurgery, ntawm qhov tod tes, yog ntau yam thiab siv tau rau ntau yam kev phais. Txawm li cas los xij, nws yuav tsum tau ceev faj thiab kev txawj ntse kom tsis txhob muaj kev kub nyhiab lossis hluav taws xob poob rau cov ntaub so ntswg nyob ze. Kev tso tus neeg mob kom zoo, tso cov khoom siv hluav taws xob, thiab kev rwb thaiv tsev ntawm cov hluav taws xob thiab cov khoom nyob ib puag ncig yog qhov tseem ceeb los tiv thaiv kev raug mob thermal.
Kev xaiv cov cuab yeej electrosurgical nyob ntawm txoj kev phais thiab tus kws phais qhov kev nyiam. Ob leeg bipolar thiab monopolar ESUs muaj lawv tus kheej daim ntawv thov, qhov zoo, thiab kev txwv. Cov pab pawg phais yuav tsum tau txais kev cob qhia zoo hauv kev siv cov cuab yeej electrosurgical thiab ua raws li cov qauv txheej txheem los xyuas kom cov neeg mob muaj kev nyab xeeb thiab ua tiav cov txiaj ntsig kev phais zoo. Nrog kev cob qhia kom raug thiab kev kho mob, electrosurgery tseem yog ib qho cuab yeej tseem ceeb rau cov txheej txheem phais niaj hnub no.
