Electrosurgery, los ntawm kev sib piv, siv xov tooj cua zaus (RF) alternating tam sim no los ua kom sov cov ntaub so ntswg los ntawm RF induced intracellular oscillation ntawm ionized molecules uas ua rau ib tug siab ntawm intracellular kub. Thaum qhov kub ntawm intracellular nce mus txog 60 degrees C, instantaneous cell tuag tshwm sim. Yog hais tias cov ntaub so ntswg yog rhuab mus rau 60-99 ° C, cov txheej txheem ib txhij ntawm cov ntaub so ntswg desiccation (lub cev qhuav dej) thiab protein coagulation tshwm sim. Yog hais tias qhov kub ntawm intracellular sai nce mus txog 100 ° C, cov ntsiab lus intracellular tau hloov ua kua rau roj, loj volumetric expansion, thiab ua rau tawg vaporization.
Tsim nyog siv nrog electrosurgical forceps, desiccation thiab coagulation tshwm sim nyob rau hauv occlusion ntawm cov hlab ntsha thiab tso tseg los ntshav. Thaum cov txheej txheem yog technically txheej txheem ntawm electrocoagulation, lub sij hawm" electrocautery" yog qee zaum xoob, nontechnically thiab siv tsis raug los piav qhia nws. Cov txheej txheem ntawm vaporization tuaj yeem siv los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau, cov txheej txheem vaporization yuav siv Thaum cov txheej txheem ntawm vaporization / txiav thiab desiccation / coagulation yog qhov zoo tshaj plaws ua tiav nrog qhov tsis tshua muaj hluav taws xob, tsis tu ncua lossis ze rau cov nthwv dej tsis tu ncua, cov txheej txheem ntawm fulguration yog ua nrog cov high voltage modulated waveforms. Fulguration yog ib hom coagulation superficial, feem ntau tsim los ntawm arcing modulated high voltage tam sim no rau cov ntaub so ntswg uas yog sai desiccated thiab coagulated. Kev siv txuas ntxiv ntawm tam sim no mus rau cov ntaub so ntswg impedance siab ua rau cov cua sov tiv taus thiab ua tiav ntawm qhov kub thiab txias heev - txaus los ua kom tawg ntawm cov organic molecules rau cov suab thaj thiab txawm tias carbon, yog li qhov tsaus nti textures los ntawm carbonization ntawm cov ntaub so ntswg.
RF electrosurgery feem ntau yog siv rau hauv txhua yam kev phais mob xws li dermatological, gynecological, cardiac, yas, ocular, txha nraub qaum, ENT, maxillofacial, orthopedic, urological, neuro- thiab cov txheej txheem phais dav dav nrog rau qee yam kev kho hniav.
