I Intangiriro
Prothèse yo mu ivi igizwe na condyle femorale, urushinge rwa tibial marrow, urushinge rwigitsina gore, igice cyaciwe nuduce twahinduwe, uruzitiro rwo hagati, tee, tray plateau tray, uburinzi bwa condylar, gushyiramo tibial plateau, gushyiramo umurongo, no kubuza ibice.
II Ibiranga ibicuruzwa biranga ivi
Kwemeza igishushanyo cyihariye, igishushanyo cya bionic yubuso bushobora guhuza imirimo isanzwe ivi;
Imiterere ya biomehanike na moderi ya elastike ya 3D yacapishijwe amagufwa ya trabecular ya interineti irahuza cyane numubiri wumuntu, kandi imiterere yubukanishi nibyiza;
Imiterere mesh ya meshi ihuza hamwe kugirango igire imiterere yubuki bwamagufwa yamagufwa hamwe na biocompatibilité nziza ya titanium alloy, ituma igufwa rikura vuba kandi neza.
Femoral Condyle Condyle Kurinda Tibial Plateau Tray (Ibumoso ugana iburyo)
III Ibyiza bya prothèse yo mu ivi
1.Imikorere myiza yo gukura amagufwa no koroshya ingirabuzimafatizo no kwinjiza
Igishushanyo 1 Gukura amagufwa yinyamaswa zifite amagufwa ya trabecular yubatswe
Ubwinshi bwibi bicuruzwa bugumishwa hejuru ya 50%, butanga umwanya uhagije wo guhanahana intungamubiri na ogisijeni, bigatera ikwirakwizwa ry’uturemangingo no gutembera kw'ingirabuzimafatizo, kandi bikagera no gukura kw'imitsi.Uturemangingo twavutse dukura mu rwobo rw'ubuso bwa prostate hanyuma ugahuza hagati ya mesh idahuye, ihujwe cyane n'urwego rwo hejuru rw'insinga ya titanium ku bujyakuzimu bwa mm 6.Amezi 3 nyuma yo kubagwa, tissue ikura muri matrix ikuzuza ahantu hose hubatswe, hamwe nubujyakuzimu bwa mm 10, kandi amezi 6 nyuma yo kubagwa, ingirabuzimafatizo zikuze zikura mumyanya yose, hamwe nibindi bikomeye. igipimo cyo kuzuza.
2.Imiterere yumunaniro mwiza
Igishushanyo cya 2 Umunaniro wibizamini bya tibial plateau tray
Isahani ya tibial yapimwe muburyo bwa ASTM F3334 kandi yerekanaga imikorere myiza yumunaniro hamwe ninshuro 10,000,000 yikizamini cyumunaniro mugihe cyo gupakira sinusoidal ya 90N-900N itavunitse.
3.Kurwanya ruswa nziza
Igishushanyo cya 3 Ubushakashatsi bwo kwangirika kwa Micromotor kuri condyle femorale no guhuza urushinge rwa medullary
Ukurikije YY / T 0809.4-2018 yipakurura isanzwe ya cyclicale kandi nta gutsindwa kuboneka, ibisubizo byerekana ko iki gicuruzwa gifite imikorere myiza ya anti-cone ya micro-moto yangirika, kugirango umutekano w’ingingo zivi umaze kwinjizwa mumubiri wumuntu.
4.Kurwanya kwambara neza
Igishushanyo cya 4 Ishusho ya prothèse yuzuye ivi yambara ibisubizo byubushakashatsi
Dukurikije ibipimo bya ISO 14243-3: 2014 kubizamini byo gupima ivi byose hamwe, ibisubizo byerekana ko ibicuruzwa bifite imbaraga zo guhangana n’imyambarire, kugirango umutekano w’ingingo zivi nyuma yo kwimikwa mu mubiri w’umuntu.
