High Frequency Electrosurgical Units-Mfundo yogwira ntchito ndi njira zodzitetezera kuti zigwiritsidwe ntchito motetezeka

Magawo amagetsi(ESU) ndi chida cha electrosurgical chomwe chimagwiritsa ntchito magetsi othamanga kwambiri podula minofu ndikuwongolera magazi poyambitsa kukomoka.Iwo amatenthetsa minofu pamene mkulu-pafupipafupi mkulu-voteji panopa kwaiye ndi ogwira elekitirodi nsonga kukhudzana ndi thupi, ndipo amazindikira kulekana ndi coagulation wa minofu ya thupi, potero kukwaniritsa cholinga kudula ndi hemostasis.

ESU ikhoza kugwiritsa ntchito monopolar kapena bipolar mode

1.Monopolar mode

Mu monopolar mode, dera lathunthu limagwiritsidwa ntchito kudula ndi kulimbitsa minofu.Dera limapangidwa ndi jenereta yothamanga kwambiri, mbale zoyipa,cholumikizira pansi pad chingwendi ma electrodes.Kutentha kwamphamvu kwa ma electrosurgical unit okwera kwambiri kumatha kuwononga minofu yomwe ili ndi matenda.Imasonkhanitsa kuchuluka kwamphamvu komanso pafupipafupi kwambiri ndipo imawononga minofu pamalo pomwe imalumikizana ndi nsonga ya electrode yothandiza.Kukhazikika kumachitika pamene kutentha kwa minofu kapena selo yokhudzana ndi electrode ikukwera mpaka kusinthika kwa mapuloteni mu selo.Kuchita opaleshoniyi kumadalira mawonekedwe a mafunde, magetsi, zamakono, mtundu wa minofu, ndi mawonekedwe ndi kukula kwa electrode.

2.Bipolar mode

Kusiyanasiyana kwa zochita kumangokhala malekezero awiri abipolar forceps, ndipo kuwonongeka ndi kusiyanasiyana kwa mphamvu za mphamvu ndizochepa kwambiri kuposa za monopolar.Ndi yoyenera kutsekereza mitsempha yaing'ono yamagazi (m'mimba mwake <4 mm) ndi machubu a fallopian.Choncho, bipolar coagulation imagwiritsidwa ntchito makamaka pa opaleshoni ya ubongo, microsurgery, makhalidwe asanu, obstetrics ndi gynecology, opaleshoni yamanja, ndi zina zotero. Chitetezo cha mayunitsi apamwamba a electrosurgical unit bipolar coagulation pang'onopang'ono akudziwika, ndipo ntchito yake ikuwonjezeka pang'onopang'ono.

Electrosurgical units ntchito mfundo

Mu opaleshoni ya electrosurgical, zomwe zikuchitika zimachokera kuelectrosurgical Pensulom'thupi la munthu, ndi kutuluka pa mbale negative.Nthawi zambiri ma frequency athu a mains ndi 50Hz.Titha kuchitanso ma electrosurgery mu band ya frequency iyi, koma yapano imatha kuyambitsa kukondoweza kwambiri mthupi la munthu ndikupangitsa imfa.Pambuyo pa mafupipafupi omwe alipo tsopano kuposa 100KHz, mitsempha ndi minofu sizimakhudzidwa ndi zamakono.Chifukwa chake, mayunitsi opangira ma electrospequency apamwamba kwambiri amasintha ma 50Hz apano a mains kukhala ma frequency apamwamba opitilira 200KHz.Mwanjira iyi, mphamvu zothamanga kwambiri zimatha kupereka chilimbikitso chochepa kwa wodwalayo.Palibe chowopsa cha kugwedezeka kwamagetsi kudzera m'thupi la munthu.Pakati pawo, ntchito ya mbale yolakwika imatha kupanga chipika chamakono, ndipo panthawi imodzimodziyo kuchepetsa kachulukidwe kameneka pa mbale ya electrode, kuteteza kuti panopa zisachoke kwa wodwalayo ndikubwerera ku mayunitsi apamwamba a electrosurgical kuti apitirize kutentha. minofu ndi kutentha wodwalayo.

Poganizira mfundo yogwiritsira ntchito mayunitsi apamwamba kwambiri a electrosurgical, tiyenera kulabadira mbali zotsatirazi zachitetezo pakagwiritsidwe ntchito:

l Kugwiritsa ntchito bwino mbale zopanda pake

Mayunitsi amakono a electrosurgical high-frequency unit ali ndi ukadaulo wodzipatula wodzipatula, ndipo ma frequency akutali amangogwiritsa ntchitombale negativengati njira yokhayo yobwereranso ku magawo apamwamba a electrosurgical unit.Ngakhale dongosolo lakutali la dera limatha kuteteza wodwala kuti asawotche kuchokera kumadera ena, silingapewe kupsa chifukwa cha zovuta ndi kugwirizana kwa mbale.Ngati malo olumikizana pakati pa mbale yoyipa ndi wodwalayo si yayikulu mokwanira, pakadali pano imakhazikika pagawo laling'ono, ndipo kutentha kwa mbale yoyipa kumawuka, zomwe zingayambitse kutentha kwa wodwalayo.Ziwerengero zikuwonetsa kuti 70% ya mayunitsi opangira opaleshoni yamagetsi amawotcha ngozi zimachitika chifukwa cha kulephera kwa mbale ya electrode kapena kukalamba.Kuti tipewe kuyaka kwa mbale yoyipa kwa wodwala, tiyenera kuwonetsetsa kuti mbaleyo ili ndi malo olumikizirana ndi wodwalayo komanso ma conductivity ake, ndipo kumbukirani kupewa kugwiritsa ntchito mobwerezabwereza.mbale zoipa zotayika.

l Malo oyenera oyika

Yesetsani kukhala pafupi kwambiri ndi malo opangira opaleshoni (koma osachepera 15cm) ndi dera lathyathyathya lokhala ndi minofu yambiri;

Chotsani tsitsi pakhungu lanu ndikulisunga laukhondo ndi louma;

Osawoloka malo opangira opaleshoni kumanzere ndi kumanja, ndipo khalani opitilira 15cm kutali ndi electrode ya ECG;

Pasakhale ma implants achitsulo, pacemakers, kapena maelekitirodi a ECG mu lupu;

Mbali yayitali ya mbaleyo ili pafupi ndi njira yamagetsi apamwamba kwambiri.

l Samalani mukayika mbale yoyipa

Mbale ndi khungu ziyenera kulumikizidwa mwamphamvu;

Sungani mbale ya polar yosalala osati kudula kapena pindani;

Pewani kuviika mbale za polar panthawi yophera tizilombo komanso kutsuka;

Ana osakwana 15Kg ayenera kusankha mbale za ana.

l Nkhani zina zofunika kuziganizira

Yang'anani ngati mizere yamagetsi ndi electrode yathyoka ndipo mawaya achitsulo akuwonekera;

Gwirizanitsani ndiPensulo ya Electrosurgicalku makina, yambani kudzifufuza nokha, ndikusintha mphamvu yotulutsa pambuyo posonyeza kuti mbale yolakwika yaikidwa bwino ndipo palibe alamu;

Pewani kupserera: miyendo ya wodwalayo imakulungidwa munsalu ndikukhazikika bwino kuti asakhudze khungu ndi khungu (monga pakati pa mkono wa wodwalayo ndi thupi).Osakhudzana ndi zitsulo zokhazikika.Sungani zouma zosachepera 4cm pakati pa thupi la wodwalayo ndi bedi lachitsulo.Insulation;

Pewani kutayikira kwa zida kapena kuzungulira kwachidule: osazunguliza waya mozungulira zinthu zachitsulo;gwirizanitsani ngati pali chipangizo cha waya pansi;

Wodwalayo akasuntha, fufuzani malo okhudzana ndi mbale yolakwika kapena ngati pali kusamuka kulikonse;
