Hoʻolauna I
ʻO ka prosthesis kuli he condyle femoral, kahi nila iwi tibial, kahi nila iwi femoral, kahi ʻāpana truncated a me nā wedges hoʻoponopono, kahi ʻauʻau medial, kahi tee, kahi pā tibial plateau, kahi mea pale condylar, kahi hoʻokomo tibial plateau, kahi liner, a me nā ʻāpana kaohi.
II Nā ʻano huahana o ka prosthesis kuli
Ke hoʻohana nei i kahi hoʻolālā pilikino, hiki i ka hoʻolālā bionic o ka ʻili hui ke hana hou i ka hana maʻamau o ka hui kuli;
ʻOi aku ka maikaʻi o nā waiwai biomechanical a me ka modulus elastic o ka interface trabecular iwi i paʻi ʻia 3D me ke kino kanaka, a ʻoi aku ka maikaʻi o nā waiwai mechanical;
Hoʻohui ka ʻano mesh porous kekahi i kekahi e hana i kahi ʻano honeycomb iwi cancellous me ka biocompatibility maikaʻi o ka titanium alloy, ka mea e hiki ai i ka iwi ke ulu wikiwiki a palekana.
ʻO ka Femoral Condyle Condyle Protector Tibial Plateau Tray (Mai ka hema a i ka ʻākau)
III Nā Pōmaikaʻi o ka prosthesis kuli
1. Hana maikaʻi loa o ka ulu ʻana o ka iwi a me nā ʻiʻo palupalu a me ka hoʻokomo ʻana
Kiʻi 1 Ka ulu ʻana o ka iwi i nā holoholona me nā ʻano trabecular iwi i hoʻokomo ʻia
Mālama ʻia ka porosity o kēia huahana ma mua o 50%, kahi e hāʻawi ai i kahi kūpono no ka hoʻololi ʻana i nā meaʻai a me ka oxygen, paipai i ka hoʻonui ʻana o nā cell a me ke vascularisation o nā cell kumu, a hoʻokō i ka ulu ʻana o nā ʻiʻo. Ulu ka ʻiʻo hānau hou i loko o ka lua o ka ʻili prosthesis a ulana i loko o kahi mesh like ʻole, kahi i hui pū ʻia me ka papa luna o ka uea titanium ma kahi hohonu o 6 mm. 3 mahina ma hope o ke ʻoki ʻana, ulu ka ʻiʻo i loko o ka matrix a hoʻopiha i ka ʻāpana porous holoʻokoʻa, me ka hohonu o 10 mm, a 6 mahina ma hope o ke ʻoki ʻana, ulu ka ʻiʻo tendon makua i loko o ka ʻōnaehana porous holoʻokoʻa, me ka nui o ka hoʻopiha ʻana.
2. Nā waiwai luhi maikaʻi loa
Kiʻi 2 Nā hopena hoʻāʻo luhi o ka pā tibial plateau
Ua hoʻāʻo ʻia ka papa tibial ma ke ʻano mīkini e like me ASTM F3334 a hōʻike i ka hana luhi maikaʻi loa me 10,000,000 mau pōʻaiapuni o ka hoʻāʻo luhi ma lalo o nā kūlana hoʻouka sinusoidal o 90N-900N me ka ʻole o ka nahā ʻana.
3. Ke kūpaʻa maikaʻi loa i ka palaho
Kiʻi 3 Nā hoʻokolohua palaho Micromotor ma ka condyle femoral a me ka medullary needle cone junction
Wahi a YY/T 0809.4-2018 maʻamau o ka hoʻouka ʻana i ka cyclic a ʻaʻohe hemahema i loaʻa, hōʻike nā hopena he hana maikaʻi loa kēia huahana anti-cone micro-motion corrosion, e hōʻoia i ka palekana o ka hui kuli ma hope o ke kau ʻana i loko o ke kino kanaka.
4.ʻO ke kūpaʻa maikaʻi loa
Kiʻi 4 Kiʻi o nā hopena hoʻokolohua no ke komo ʻana i nā prosthesis kuli holoʻokoʻa
Wahi a ke kūlana ISO 14243-3:2014 no ka hoʻāʻo hoʻokolohua no ka ʻaʻahu ʻana o ka hui kuli holoʻokoʻa, hōʻike nā hopena he kūpaʻa maikaʻi loa ka huahana i ka ʻaʻahu ʻana, e hōʻoia i ka palekana o ka hui kuli ma hope o ke kanu ʻana i loko o ke kino kanaka.
