Electrosurgical units(ESU) yog ib qho khoom siv hluav taws xob uas siv hluav taws xob ntau zaus los txiav cov nqaij mos thiab tswj cov ntshav los ntawm kev ua rau coagulation.Nws heats cov ntaub so ntswg thaum lub high-frequency high-voltage tam sim no generated los ntawm cov zoo electrode tip nyob rau hauv kev sib cuag nrog lub cev, thiab paub qhov sib cais thiab coagulation ntawm lub cev nqaij daim tawv, yog li ua tiav lub hom phiaj ntawm kev txiav thiab hemostasis.
ESU tuaj yeem siv hom monopolar lossis hom bipolar
1.Monopolar hom
Nyob rau hauv hom monopolar, ib tug ua tiav Circuit Court yog siv los txiav thiab solidify cov ntaub so ntswg.Lub Circuit Court muaj lub tshuab hluav taws xob siab, tsis zoo phaj,connector grounding ncoo cablethiab electrodes.Cov nyhuv cua sov ntawm high-frequency electrosurgical units tuaj yeem rhuav tshem cov kab mob.Nws sib sau ua ke high-density thiab high-frequency tam sim no thiab rhuav tshem cov ntaub so ntswg ntawm qhov chaw uas nws hu rau lub ntsis ntawm cov electrode zoo.Solidification tshwm sim thaum qhov kub ntawm cov ntaub so ntswg los yog cell nyob rau hauv kev sib cuag nrog lub electrode nce mus rau lub denaturation ntawm cov protein nyob rau hauv lub cell.Qhov kev phais qhov tseeb no nyob ntawm qhov waveform, voltage, tam sim no, hom ntaub so ntswg, thiab cov duab thiab qhov loj ntawm electrode.
2.Bipolar hom
Qhov ntau ntawm kev ua yog txwv rau ob qhov kawg ntawm qhovbipolar quab yuam, thiab qhov kev puas tsuaj thiab qhov ntau ntawm kev cuam tshuam ntawm forceps yog ntau me dua li ntawm monopolar.Nws yog tsim rau thaiv cov hlab ntsha me me (inch <4 mm) thiab cov hlab ntsha fallopian.Yog li ntawd, bipolar coagulation yog tsuas yog siv nyob rau hauv lub hlwb phais, microsurgery, tsib yam ntxwv, obstetrics thiab gynecology, tes phais, thiab lwm yam.
Electrosurgical units ua hauj lwm hauv paus ntsiab lus
Hauv kev phais electrosurgical, tam sim no ntws los ntawm lubelectrosurgical cwj memrau hauv tib neeg lub cev, thiab ntws tawm ntawm lub phaj tsis zoo.Peb lub ntsiab zaus yog 50Hz.Peb kuj tuaj yeem ua electrosurgery nyob rau hauv qhov zaus band, tab sis tam sim no yuav ua rau muaj kev stimulation ntau dhau rau tib neeg lub cev thiab ua rau tuag taus.Tom qab qhov zaus tam sim no tshaj 100KHz, cov hlab ntsha thiab cov leeg tsis hnov mob tam sim no.Yog li ntawd, lub high-frequency electrosurgical units converts 50Hz tam sim no ntawm lub mains mus rau ib tug high-frequency tam sim no tshaj 200KHz.Nyob rau hauv txoj kev no, lub zog siab zaus tuaj yeem muab kev txhawb nqa me me rau tus neeg mob.Tsis muaj kev phom sij ntawm hluav taws xob los ntawm tib neeg lub cev.Ntawm lawv, lub luag haujlwm ntawm lub phaj tsis zoo tuaj yeem tsim lub voj voog tam sim no, thiab tib lub sijhawm txo qhov ceev tam sim no ntawm cov phaj electrode, kom tsis txhob muaj qhov tam sim no tawm hauv tus neeg mob thiab rov qab mus rau lub tshuab hluav taws xob hluav taws xob ntau ntxiv kom sov. cov ntaub so ntswg thiab hlawv tus neeg mob.
Raws li txoj cai ua haujlwm ntawm high-frequency electrosurgical units, peb yuav tsum tau xyuam xim rau cov nram qab no kev ruaj ntseg yam thaum siv:
l Kev nyab xeeb siv cov phaj tsis zoo
Tam sim no high-frequency electrosurgical units yog txawm peem rau nrog high-frequency cais technology, thiab cais high-frequency tam sim no tsuas yog siv lubphaj tsis zooraws li tib lub channel rov qab mus rau high-frequency electrosurgical units Circuit Court.Txawm hais tias lub kaw lus sib cais tuaj yeem tiv thaiv tus neeg mob los ntawm kev kub hnyiab los ntawm lwm qhov Circuit Court, nws tsis tuaj yeem zam kev kub hnyiab los ntawm teeb meem nrog cov phaj tsis zoo.Yog hais tias qhov chaw sib cuag ntawm lub phaj tsis zoo thiab tus neeg mob tsis loj txaus, qhov tam sim no yuav muaj nyob rau hauv ib qho chaw me me, thiab qhov kub ntawm lub phaj tsis zoo yuav nce, uas yuav ua rau kub hnyiab rau tus neeg mob.Kev txheeb xyuas qhia tau hais tias 70% ntawm cov ntaub ntawv tshaj tawm cov khoom siv hluav taws xob ntau zaus hluav taws xob kub hnyiab tau tshwm sim los ntawm kev ua tsis tiav ntawm cov phaj tsis zoo electrode lossis kev laus.Txhawm rau kom tsis txhob kub hnyiab ntawm lub phaj tsis zoo rau tus neeg mob, peb yuav tsum xyuas kom meej qhov chaw sib cuag ntawm lub phaj tsis zoo thiab tus neeg mob thiab nws cov conductivity, thiab nco ntsoov kom tsis txhob rov siv cov khoom siv.pov tseg tsis zoo phaj.
l Tsim nyog qhov chaw teeb tsa
Sim ua kom ze li sai tau rau qhov chaw ua haujlwm (tab sis tsis pub tsawg dua 15cm) nrog rau cov hlab ntsha uas muaj cov leeg nqaij;
Tshem tawm cov plaub hau ntawm daim tawv nqaij hauv zos thiab ua kom nws huv si thiab qhuav;
Tsis txhob hla qhov chaw ua haujlwm sab laug thiab sab xis, thiab nyob deb tshaj 15cm ntawm ECG electrode;
Yuav tsum tsis muaj hlau cog, pacemakers, lossis ECG electrodes hauv lub voj;
Sab ntev ntawm lub phaj yog nyob ze rau cov kev taw qhia ntawm high-frequency tam sim no.
l Ua tib zoo saib thaum txhim kho lub phaj tsis zoo
Lub phaj thiab daim tawv nqaij yuav tsum nruj nreem txuas;
Khaws lub phaj polar tiaj tiaj thiab tsis txiav los yog quav;
Tsis txhob ntub cov phaj polar thaum ntxuav thiab ntxuav;
Cov menyuam yaus qis dua 15Kg yuav tsum xaiv cov ntawv me me.
l Lwm yam teeb meem xav tau kev saib xyuas
Xyuas seb cov khoom siv hluav taws xob thiab cov kab hluav taws xob puas tawg thiab cov hlau xaim raug puas lawm;
Txuas lubElectrosurgical mem hluavmus rau lub tshuab, pib qhov kev kuaj xyuas tus kheej, thiab kho lub zog tso zis tom qab nws pom tias cov phaj tsis zoo raug teeb tsa kom raug thiab tsis muaj lub tswb ceeb toom;
Tsis txhob hla kev kub hnyiab: tus neeg mob cov ceg ceg tau muab qhwv hauv daim ntaub thiab kho kom zoo kom tsis txhob sib cuag ntawm daim tawv nqaij (xws li ntawm tus neeg mob caj npab thiab lub cev).Tsis txhob tiv tauj nrog cov hlau hauv av.Khaws tsawg kawg 4cm ntawm qhov qhuav ntawm tus neeg mob lub cev thiab lub txaj hlau.Rwb thaiv tsev;
Tsis txhob cuam tshuam cov khoom siv los yog luv luv: tsis txhob cua cov hlau nyob ib ncig ntawm cov khoom hlau;txuas nws yog tias muaj cov khoom siv hauv av;
Tom qab tus neeg mob txav mus los, xyuas qhov chaw tiv tauj ntawm lub phaj tsis zoo lossis seb puas muaj kev hloov pauv;
