Zomwe zimagwiritsidwa ntchito ndi Mtsempha wa Mtsempha

Mafakitale Omwe Anakhazikitsidwa Ankaletsedwa Kapena Kusintha Mavuto A Mitsempha

Kugwedeza kwa msana (SCS) ndi njira yachipatala imene imagwiritsidwa ntchito popereka mphamvu zamagetsi zochepa pamphepete mwa msana kuti asinthe kapena kuletsa chizindikiro cha ululu ku ubongo.

SCS idagwiritsiridwa ntchito koyamba kuti imve kupweteka mu 1967 ndipo kenako inavomerezedwa kuti igwiritsidwe ntchito ndi US Food and Drug Administration mu 1989 kuti athetsere zowawa zomwe zimayambitsa kuwonongeka kwa mitsempha mu thunthu, mikono, kapena miyendo (kuphatikizapo kupweteka kwa msana, kupweteka kwa mwendo, ndi kubwerera mmbuyo opaleshoni).

Chipangizocho chimayikidwa pafupi ndi mzere wa msana ndipo chimagwira ntchito mofanana ndi mtima wopanga mtima . M'malo mwa ululu, munthu nthawi zambiri amamva phokoso lakuda-ndi-singano kumva. Machitidwe atsopano, monga Senza zokakamiza dongosolo kuvomerezedwa mu 2015, akhala akugonjetsa kwambiri izi.

Ndondomeko ya SCS ili ndi zigawo zinayi zomwe zimagwirira ntchito limodzi kuti zithetse magetsi ku magwero a ululu (wotchedwanso kupweteka kwa jenereta). Zambiri zamakono lero zimalemera pang'ono kuposa ounce ndipo zimakhala ndi jenereta yamagetsi, kutsogolo kwa magetsi, mphamvu yakude, ndi recharger ya batri.

Mmene Mungayambitsire Pulojekiti Yopanga

Jenereta yotulutsa pulani (IPG) ndilo gawo lalikulu la dongosolo la SCS. Zili ngati kukula kwa chophimba cha vanilla ndipo amachitidwa opaleshoni kudzera m'mimba kapena m'deralo. Mtsinje wa magetsi umathamanga kuchokera ku IPG kupita ku dera la epidural mu ngalande ya msana.

Dera la epidural ndilo pakati pa chivundikiro cha msana (wotchedwa dura mater) ndi khoma lozungulira. Ndipamene mankhwala opatsirana amadzipiritsidwa kwambiri kuti asamve ululu panthawi yoyembekezera.

Ambiri a IPGs lero ali ndi batri yotsitsimutsa, ngakhale kuti miyambo yachikhalidwe, yomwe siidzatha kukonzanso.

Kutsogolera ndi Electrode

Zitsogozo za dongosolo la SCS ndizopanda magetsi omwe amachokera ku IPG yomwe imalandira ndikupereka magetsi. Zili zosiyana ndi zingwe za galimoto zomwe zimagwiritsidwa ntchito kupititsa magetsi kuchokera ku batri wamoyo kwa wakufa.

Kumapeto kwa chitsogozo chilichonse ndi electrode yomwe imayikidwa mu chipinda cha epidural. Pali mitundu iwiri ya kutsogolera:

• Zovuta zogwiritsa ntchito (kutanthauza "pansi pa khungu") zomwe zimayikidwa minofu yofewa ndi chophweka chophweka
• Njira yopangira opaleshoni yomwe, monga dzina lawo ikutanthauza, imayikidwa pa opaleshoni ya m'mbuyo

Kutalikirana Kwambiri

Ma IPG atsopano apangidwa kuti muthe kuyendetsa msinkhu wa zokopa. Izi zimagwiritsidwa ntchito pogwiritsa ntchito chipangizo chakutali chomwe chinakonzedweratu.

Kulamulira kwina kungakhale kofunika kuti musinthe zinthu ngati IPG yanu ikakhudzidwa ndi kusokonezeka kwa magetsi (EMI). Izi zikhoza kuchitika ngati mutayandikira zipangizo, monga zipangizo zamakono a ndege, zomwe zimapanga mphamvu yogwiritsa ntchito magetsi. Mukagwidwa ndi EMI, IPG ikhoza kuchoka kapena kuwonjezeka kufika pa mlingo umene magetsi sakhala amphamvu kwambiri.

Malo akutali amakulolani kuti musinthe kanthawi kapenanso mutseke pulogalamuyo ngati mukufunikira. Mosiyana ndi pacemaker, yomwe siingakhoze kutsekedwa, stimulator ya msana umatha.

Batani Yowonjezera

Pali angapo a IPG omwe amagwiritsidwa ntchito lerolino omwe sangathe kubwezeretsanso, ndipo zikuwonekeratu chifukwa chake. Zigulu zakale, zomwe sizitha kubwezeretsa zimakhala ndi moyo wa batri wa pakati pa zaka ziwiri ndi zisanu. Otsopano akhoza kukhala zaka 10 mpaka 25, akupereka mwayi kwa ogwiritsira ntchito ufulu komanso opaleshoni yochepa yopaleshoni.

Batri ya IPG imabwezeretsedwa mwa kuika kachilombo kansalu kameneka khungu pamtundu umodzi. Amagwiritsidwa ntchito ndi kansalu ka belt yosinthika ndipo kawirikawiri amatenga maola angapo mlungu kuti abwezeretsenso. Chizindikiro cha beep ndi / kapena chounikira chidzakuuzani pamene batiri ikubwezeretsanso.
