Electrosurgical Units

Lub tshuab electrosurgical yog ib qho khoom siv phais siv los ua cov ntaub so ntswg, rhuav tshem cov ntaub so ntswg los ntawm desiccation, thiab tswj los ntshav (hemostasis) los ntawm kev ua rau cov ntshav coagulation.Qhov no yog ua tiav nrog lub tshuab hluav taws xob siab thiab lub tshuab hluav taws xob siab uas ua rau lub tshuab hluav taws xob (RF) qhov hluav taws xob nruab nrab ntawm qhov kev sojntsuam thiab qhov chaw phais uas ua rau cov cua sov hauv cheeb tsam thiab kev puas tsuaj rau cov ntaub so ntswg.

Lub tshuab hluav taws xob electrosurgical ua haujlwm hauv ob hom.Nyob rau hauv hom monopolar, lub active electrode concentrates lub tam sim no mus rau qhov chaw phais thiab ib tug dispersive (rov qab) electrode raws li tam sim no deb ntawm tus neeg mob.Hauv hom bipolar, ob qho tib si nquag thiab rov qab electrodes nyob ntawm qhov chaw phais.

Thaum cov txheej txheem phais, cov kws phais siv electrosurgical units (ESU) txiav thiab coagulate cov ntaub so ntswg.ESUs tsim hluav taws xob tam sim no ntawm qhov siab zaus ntawm qhov kawg ntawm cov khoom siv hluav taws xob.Qhov no tam sim no txiav thiab coagulates cov ntaub so ntswg.Qhov zoo ntawm cov thev naus laus zis no dhau ntawm cov pa scalpel yog ib txhij txiav thiab coagulating thiab yooj yim ntawm kev siv hauv ntau cov txheej txheem (xws li phais endoscopyprocedures).

Cov teeb meem tshwm sim feem ntau yog kub hnyiab, hluav taws kub thiab hluav taws xob poob siab.Hom kev hlawv no feem ntau tshwm sim nyob rau hauv cov khoom siv electrode ECG, nyob rau hauv ESU grounding, tseem hu ua rov qab los yog dispersive electrode), los yog nyob rau hauv ntau qhov chaw ntawm lub cev uas tej zaum yuav nyob rau hauv kev sib cuag nrog ib tug rov qab txoj kev rau ESU tam sim no, piv txwv li, caj npab, hauv siab, thiab ob txhais ceg.Hluav taws kub tshwm sim thaum cov kua hluav taws xob tuaj yeem tiv nrog cov hluav taws los ntawm ESU nyob rau hauv muaj cov oxidant.Feem ntau cov xwm txheej no pib tsim cov txheej txheem sib kis hauv qhov chaw ntawm qhov kub hnyiab.Qhov no tuaj yeem ua rau muaj kev cuam tshuam loj rau tus neeg mob thiab feem ntau ua rau tus neeg mob nyob hauv tsev kho mob.

Kev nyab xeeb

Thaum siv kom raug, electrosurgery yog txoj kev nyab xeeb.Cov phom sij tseem ceeb thaum siv lub tshuab hluav taws xob hluav taws xob yog los ntawm qhov tsis tshua muaj tshwm sim ntawm qhov tsis xav tau hauv av, kub hnyiab thiab muaj kev pheej hmoo ntawm kev tawg.Kev tsis ncaj ncees hauv av tuaj yeem zam tau los ntawm kev siv zoo ntawm cov khoom siv hluav taws xob dispersal thiab tshem tawm cov khoom hlau los ntawm thaj chaw ua haujlwm.Tus neeg mob lub rooj zaum yuav tsum tsis txhob muaj hlau uas tuaj yeem kov tau yooj yim thaum kho.Cov trolleys ua haujlwm yuav tsum muaj cov iav los yog yas.

Kev kub hnyiab tuaj yeem tshwm sim yog tias cov phaj dispersal siv tsis zoo, tus neeg mob tau cog cov hlau los yog muaj cov caws pliav khaus ntawm lub phaj thiab ceg.Qhov txaus ntshai yog tsawg dua nyob rau hauv podiatry, qhov chaw tshuaj loog yog hauv zos thiab tus neeg mob tsis nco qab.Yog tias tus neeg mob yws yws txog cua sov nyob qhov twg hauv lub cev, kev kho mob yuav tsum tau nres kom txog thaum pom qhov chaw thiab qhov teeb meem daws tau.

Txawm hais tias cov khoom siv thaum muaj xwm txheej ceev yuav tsum muaj nyob rau hauv rooj plaub ntawm kev sib tsoo, lub tog raj kheej siab xws li cov pa oxygen yuav tsum tsis txhob muab cia rau hauv chav uas muaj kev phais electrosurgery.

Yog hais tias preoperative antiseptic muaj cawv, daim tawv nqaij saum npoo yuav tsum qhuav kiag li ua ntej siv cov activated sojntsuam.Ua tsis tiav qhov no yuav ua rau cov cawv seem ntawm daim tawv nqaij ua rau kub hnyiab, uas tuaj yeem ceeb toom tus neeg mob.
