Yuav Ua Li Cas Disposable Radiofrequency Ablation Ua Haujlwm?

Ua ntej, kev tshuaj xyuas electrophysiological tau ua los ntawm kev ntxig rau hauv cov hlab ntsha hauv cov hlab ntsha lossis cov hlab ntsha subclavian thiab ob sab femoral leeg rau hauv lub plawv catheter electrode kom paub meej tias qhov kev kuaj mob thiab qhov chaw ntawm qhov txhab raug tshem tawm. Thiab tom qab ntawd xaiv tus tsov ntxhuav feem ntawm qhov tshwj xeeb ablation catheter rau qhov txhab, ib lub sij hawm luv luv ntawm lub sij hawm los tso cov xov tooj cua tam sim no, tam sim no rau 20 mus rau 30 watts, xov tooj cua zaus tam sim no nyob rau hauv kev sib cuag nrog cov ntaub so ntswg myocardial tom qab ib nrab kuj kub, yog li ntawd. hais tias lub zos myocardial cov ntaub so ntswg necrosis qhuav, cov ntaub so ntswg necrotic twb tsis ua lub luag hauj lwm xa hluav taws xob signals, yog li arrhythmia yog eradicated. Qhov kev puas tsuaj los ntawm cov xov tooj cua zaus tam sim no rau myocardium yog qhov chaw hauv cheeb tsam, txog 3-4 mm inch thiab qhov tob, thiab tsis cuam tshuam rau lub plawv ua haujlwm. Kev ua haujlwm tau ua tiav thaum lub ablation tau lees paub los ntawm intracardiac electrophysiological kuaj. Kev ua haujlwm yog ua raws li kev siv tshuaj loog hauv zos, thiab tus neeg mob tsaug zog thaum lub sijhawm ua haujlwm thiab tuaj yeem qhia tus kws kho mob txog nws txoj kev xav txhua lub sijhawm. Tom qab cov txheej txheem tiav lawm, cov neeg mob feem ntau tau nce thiab txog hnub tom qab thiab tuaj yeem tawm hauv tsev kho mob hauv ob mus rau peb hnub. Cov xwm txheej tam sim no uas tuaj yeem kho tau nrog cov txheej txheem no suav nrog kev mob plab ua ntej thiab paroxysmal supraventricular tachycardia, atrial flutter thiab atrial fibrillation, ventricular tachycardia, thiab atrial tachycardia tshwm sim los ntawm ob txoj kev atrioventricular node. Ntawm lawv, PARoxysmal ventricular tachycardia ntawm tus nqi radical tuaj yeem ncav cuag 90 feem pua ​​​​ntawm saum toj no, qhov kho tus nqi ntawm ventricular tachycardia yog li 50 feem pua ​​​​ntawm sab laug thiab sab xis. Radiofrequency ablation ntawm atrial tachycardia, flutter, thiab atrial fibrillation yog tam sim no nyob rau hauv kev sim tshuaj. 4. Percutaneous radiofrequency ablation (RFA) ntawm cov qog yog siv los tshem tawm cov qog los ntawm cov nqaij mos coagulation necrosis tshwm sim los ntawm radiofrequency heat effect raws li kev taw qhia ntawm cov duab (CT, B-ultrasound, thiab lwm yam), uas tau dhau los ua qhov hotspot tshiab hauv ntau txoj kev kho mob palliative. . Lub hauv paus ntsiab lus tseem ceeb ntawm cov cuab yeej siv no yog lub taub hau ntawm lub taub hau tawm qhov nruab nrab thiab siab zaus xov tooj cua zaus nthwv dej (460K Hz), uas tuaj yeem txhawb nqa cov ntaub so ntswg kom tshem tawm cov ntshav plasma, thiab cov ions sib tsoo nrog ib leeg los ua kom sov, ncav cuag {{8 }} degree , uas tuaj yeem tua cov qog hlwb hauv zos. Nyob rau tib lub sijhawm, nws tuaj yeem ua rau cov hlab ntsha nyob ib puag ncig cov qog coagulate thiab tsim cov tshuaj tiv thaiv. Nws tsis tuaj yeem muab cov ntshav mus ntxiv rau cov qog thiab pab tiv thaiv qog nqaij hlav metastasis. Tag nrho cov txheej txheem kho mob yog tswj los ntawm lub computer thiab saib xyuas los ntawm TV screen. Radiofrequency yoj tawm los ntawm pawg electrode tuaj yeem ua rau cov ntaub so ntswg coagulated necrosis cheeb tsam (cov qog tsis ua haujlwm) txog li 5cm × 5cm × 5cm ib zaug. Nws yog qhov zoo tshaj plaws "kev coj noj coj ua txoj kev kho mob" thiab kev kho mob qog noj ntshav tsawg tsawg, uas tuaj yeem tua cov qog ntau dua thiab ua rau lub cev tsis zoo.
