Ku barwayi bagiye gusimbuzwa ikibuno cyangwa batekereza gusimbuzwa ikibuno mu gihe kiri imbere, hari ibyemezo byinshi by'ingenzi bagomba gufata. Icyemezo cy'ingenzi ni uguhitamo ubuso bushyigikira ingingo kugira ngo ingingo zisimbuzwe: icyuma-ku-icyuma, icyuma-ku-poliyelene, ceramic-ku-poliyelene, cyangwa ceramic-ku-ceramic. Hari igihe ibi bishobora kuba ikibazo!
Kubaga ingingo zose zo mu kibuno bishobora gukoreshwa mu gusimbuza ingingo yo mu kibuno ifite rubagimpande, hakoreshejwe icyuma cy’ubukorano kugira ngo ububabare buterwa no gukaraba ahantu hakorerwa isuku.
Insimburangingo z’ubukorano zigenewe guha abarwayi ubushobozi bwo kugumana ubusugire no kwangirika guke. Insimburangingo gakondo z’icyuma na polyethylene zakoreshejwe kuva mu myaka ya 1960, ariko iterambere mu ikoranabuhanga ryatumye ibikoresho bya ceramic n’ibindi birushaho gukundwa.
Ibikoresho byo gusimbuza ingingo zo mu kibuno
Kimwe mu bibazo bikunze kugaragara nyuma yo gusimbuza ikibuno ni ukwangirika no gucika kw'ingingo z'umubiri zikoreshwa mu buryo busanzwe. Bitewe n'imimerere yihariye y'umurwayi, nk'imyaka, ingano, urwego rw'imikorere, n'uburambe bw'umuganga ubaga iyo afashe iyi mashini, iyi mashini isimbura ikibuno ishobora kuba ikozwe mu cyuma, polyethylene (plastiki), cyangwa ibumba. Urugero, niba umurwayi akora cyane cyangwa akiri muto kandi akaba akeneye kugenda cyane nyuma yo kubagwa, umuganga ubaga amagufwa ashobora kumusaba kuyishyiraho ibumba ry'umubiri.
1、Umutwe w'umupira w'icyuman'igitambaro cya polyethylene (plastiki).
Imipira isanzwe y'icyuma n'udupira twa polyethylene byakoreshejwe kuva mu ntangiriro za 1960. Ubushakashatsi bwa siyansi bwerekana ko ikoreshwa ry'udupira twa polyethylene twanonosoye, tuzwi nka "highly-linked cross-linked" polyethylene liners, bishobora kugabanya cyane igipimo rusange cy'udupira twa implants. Bitewe no kuramba kwayo n'izindi miterere bifitanye isano, polyethylene y'icyuma ni yo yari ikoreshwa cyane n'abaganga b'amagufwa mu gukora ibice by'ikibuno by'ubukorano kuva aho babazwe bwa mbere mu gusimbuza ikibuno. Umupira w'icyuma ukozwe muri cobalt-chromium alloy naho agace k'imbere kakozwe muri polyethylene.
2、Umutwe w'umupira w'ibumban'urukuta rwa polyethylene (plastiki)
Impande za ceramic zirakomeye kurusha icyuma kandi ni zo zikoreshwa mu kubaga ingingo zisimbura ingingo. Ceramics ikoreshwa ubu mu kubaga ingingo zifite ubuso bukomeye, budashobora gushwara kandi bworoshye cyane bushobora kugabanya cyane imbaraga zo kwangirika kw'imirongo ya polyethylene. Igipimo cyo kwangirika kw'iyi plant kiri hasi ugereranyije n'igipimo cyo kwangirika kw'icyuma kuri polyethylene.
3Umutwe w'umupira w'icyuma n'icyuma gifunganye
Uburyo bwo gukururana kw'ibyuma (cobalt-chromium alloys, rimwe na rimwe icyuma kidashonga) bwakoreshejwe kuva mu 1955, ariko ntibwemejwe na FDA ngo bukoreshwe muri Leta Zunze Ubumwe za Amerika kugeza mu 1999. Uko ikoranabuhanga rigenda ritera imbere, kwangirika kugabanuka cyane, bigatuma ubushyuhe n'amagufwa bigabanuka. Udupira tw'ibyuma turaboneka mu bunini butandukanye (kuva kuri mm 28 kugeza kuri mm 60), ndetse n'uburyo butandukanye bwo guhagarara mu ijosi. Ariko, raporo z'igihe kirekire nyuma yo kubagwa zigaragaza ko icyuma, nk'iyoni ikora cyane, gikusanya imyanda y'icyuma bitewe no kwangirika no gucika kw'igihe kirekire, bishobora gutuma amagufwa ashonga hirya no hino ku ngingo, amaherezo bigatera gucika no guhindagurika kw'ingingo. Igikorwa cyarananiranye.
4Umutwe w'umupira wa keramike n'umutweigitambaro cy'ibumba
Muri izi mpundu, imipira gakondo y'icyuma n'imitako ya polyethylene byasimbuwe n'ibibumbano bikomeye cyane, bizwiho kuba bifite ubushobozi bwo kwangirika buhoro cyane. Ariko, nubwo bifite ibyiza byo kwangirika no kwangirika buhoro, nta gushidikanya ko bifite n'ingaruka mbi zo guhenda cyane.
Amahitamo ya nyuma y’imashini itera umubiri izagenwa hashingiwe ku buzima bw’umurwayi, kandi bizasaba kandi ubuhanga bw’umuganga w’amagufwa, uburezi, n’ubuhanga bw’umuganga w’amagufwa kugira ngo ahindure ibicuruzwa by’uruganda runaka. Kubwibyo, ni ngombwa kuganira n’umuganga w’amagufwa mbere yo kubagwa kugira ngo usobanukirwe ubwoko bw’imashini ateganya gukoresha mu kubaga ikibuno cyawe, n’impamvu zo guhitamo imashini runaka.
