Izingxenye zohlelo lwe-Spinal Cord Ukuvuselela

Amadivaysi asetshenziselwe ukuvimbela noma ukuguqula ubuhlungu bezinzwa

Ukuvuselela intambo yomgogodla (SCS) yindlela yokwelapha esetshenziselwa ukuletha izimpumputhe zamandla kagesi emithonjeni ukuze uguqule noma uvimbele izibonakaliso zobuhlungu ebuchosheni.

I-SCS isetshenziswe okokuqala ukuphatha ubuhlungu ngo-1967 futhi kamuva yamukelwa ukusetshenziswa kwe-US Food and Drug Administration ngo-1989 ukuze kukhululwe ubuhlungu obubangelwa ukulimala kwamagciwane esiqu, izingalo, noma imilenze (kuhlanganise nobuhlungu obuphansi emuva, ubuhlungu bomlenze, nokuhluleka emuva ukuhlinzwa).

Idivayisi ifakwe eduze kwekholomu yomgogodla futhi isebenza ngokufanayo nomoya wokuvutha kwenhliziyo . Esikhundleni sobuhlungu, umuntu uyozizwa ephethe izikhonkwane ezikhanyayo-nezinaliti. Izinhlelo ezintsha, njengeSenza uhlelo lokuvuselela olwamukelwa ngo-2015, liye lakwazi ukunqoba kakhulu lokhu.

Uhlelo lwe-SCS luqukethe izingxenye ezine ezisebenza ndawonye ukuletha ukuvuselela kagesi kumthombo wobuhlungu (owaziwa nangokuthi ubujenerali buhlungu). Amadivaysi amaningi namuhla anesisindo esincane kakhulu kunesisindo futhi anesakhi se-generator, umzila kagesi, isilawuli esikude, ne-recharger yebhethri.

I-Generator Pulse Generator

I-generator generated pulse (IPG) iyisici esiyinhloko saso sonke isimiso se-SCS. Kungaba ngubukhulu besinkwa se-vanilla futhi senziwa ngokuhlinzwa ngesikhumba esiswini noma endaweni yezilwane. Imikhombandlela kagesi iyasebenza kusukela ku-IPG kuya esikhaleni se - epidural emgodini ongasemgogodini.

Isikhala se-epidural yiyona ndawo ephakathi kwesembozo somgogodla (okuthiwa i-mater dura) nodonga lwama-vertebral. Yilapho imishanguzo ye-anesthetic ivame ukujova ukuvimbela ubuhlungu ngesikhathi sokukhulelwa.

Iningi le-IPGs namuhla lixhaswa ibhetri elishayekayo, nakuba amayunithi wendabuko, engekho alayishiwe angasetshenziswa.

Ukuhola kanye nama-Electrodes

Umkhombandlela wesistimu ye-SCS yizintambo ezifakiwe ezivela ku-IPG ezitholayo futhi zanikeza ukushayela kagesi. Azifani nezintambo ze-jumper ezisetshenziselwa ukudlulisa ugesi kusuka kubhethri bukhoma kumuntu ofile.

Ekupheleni komthofu ngamunye yi-electrode efaka isikhala esiphezulu. Kunezinhlobo ezimbili eziyinhloko zokuhola:

• Imikhombandlela ehamba phambili (incazelo engezansi "ngaphansi kwesikhumba") efakwe ezicubu ezithambile nge-incision elula
• Ukuhamba okuhlinzekwayo, okubizwa ngokuthi igama labo, kufakwa ngesikhathi sokuhlinzwa kwangemuva

Ukulawula kude

Ama-IPG amasha aklanyelwe ukuze ukwazi ukulawula izinga lokuvuselela ngezinga elithile. Lokhu kwenziwa ngokusebenzisa idivaysi yokulawula eyikude ehlelwe ku-unit yakho ethize.

Ukulawula okude kungabalulekile ekwenzeni izinguquko uma i-IPG yakho ishintshiswa ngokuphazanyiswa kwe-electromagnetic (EMI). Lokhu kungenzeka uma ngabe ususeduze nemishini, njengamadivayisi okuphepha ezindiza, okwenza insimu enamandla kagesi. Uma hit nge-EMI, i-IPG ingavala noma ikhuphukele ezingeni lapho ukushayela kagesi kungasebenzi kahle.

I-remote ikuvumela ukuba ulungise okwesikhashana noma ususe ucingo uma kudingeka. Ngokungafani ne-pacemaker, engakwazi ukuvulwa, i-stimulator yomshoshaphansi ingakwazi.

I-Battery Recharger

Kunezinhlobo ezimbalwa ze-IPG ezisetshenzisiwe namuhla ezingasetshenziswanga, futhi kucacile ukuthi kungani. Amayunithi asebekhulile, angakhokhelwa anempilo yebhethri phakathi kweminyaka emibili nanhlanu. Amasha angakwazi ukugcina iminyaka engu-10 kuya kweyengu-25, enikeza abasebenzisi inkululeko enkulu futhi ukungenelela okuncane kakhulu kokuhlinzwa.

Ibhethri ye-IPG ivuselelwa ngokubeka i-recharger engenazintambo esikhumbeni ngokuqondile phezu kweyunithi. It is in place by a adjustable belt strap futhi ngokuvamile kuthatha amahora amaningana ngesonto ukuvuselela ngokuphelele. Isibonisi se-beep kanye / noma ukukhanya sizokutshela uma ibhethri ivuselelwa ngokugcwele.
