ʻO ka prosthesis o ke kuli he condyle femoral, he nila tibial marrow, he nila femoral marrow, kahi ʻāpana i ʻoki ʻia a me nā wedges hoʻoponopono, kahi kumu waena, kahi tee, kahi pā pālahalaha tibial, kahi pale condylar, kahi hoʻokomo ʻia ʻana o ka tibial plateau, kahi liner, a me nā ʻāpana kaohi.
II Nā hiʻohiʻona huahana o ka prosthesis kuli
Hoʻohana i ka hoʻolālā pilikino, hiki i ka hoʻolālā bionic o ka ʻili hui ke hana hou i ka hana hui kuli maʻamau;
ʻO nā waiwai biomechanical a me ka modulus elastic o ka 3D iwi paʻi trabecular interface ʻoi aku ka paʻakikī me ke kino kanaka, a ʻoi aku ka maikaʻi o nā waiwai mechanical;
Hoʻohui ʻia ke ʻano porous mesh me kekahi i kekahi e hana i kahi honeycomb iwi cancellous me ka biocompatibility maikaʻi o ka titanium alloy, e hiki ai i ka iwi ke ulu wikiwiki a paʻa.

III ʻO nā pono o ka pale kuli
1.Excellent hana o ka iwi a me ka palupalu i ka ulu a me ka hookomo
Fig. 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%, e hāʻawi ana i kahi kūpono no ka hoʻololi ʻana i ka meaʻai a me ka oxygen, hoʻoikaika i ka hoʻonui ʻana o ka cell a me ka vascularization o nā pūnaewele, a loaʻa i ka ulu ʻana o ka ʻiʻo.Ke ulu nei ka ʻiʻo hānau hou i loko o ka pore o ka ʻili prosthesis a hoʻopili ʻia i loko o kahi mesh like ʻole, i hui pū ʻia me ka papa luna o ka uea titanium ma kahi hohonu o 6 mm.3 mau mahina ma hope o ka ʻoki ʻana, ulu ka ʻiʻo i loko o ka matrix a hoʻopiha i ka wahi o ka hale porous holoʻokoʻa, me ka hohonu o kahi o 10 mm, a me 6 mau mahina ma hope o ke ʻoki ʻana, ulu ka ʻiʻo tendon makua i loko o ka hale porous holoʻokoʻa, me kahi mea nui aʻe. hoʻopiha piha.
2.Excellent luhi waiwai
Fig. 2 Nā hopena ho'āʻo luhi o ka pā pāpū tibial
Ua hoʻāʻo ʻia ka papa tibial e like me ka ASTM F3334 a hōʻike i ka hana luhi maikaʻi loa me 10,000,000 pōʻai o ka hoʻāʻo luhi ma lalo o nā kūlana hoʻouka sinusoidal o 90N-900N me ka ʻole o ka haki ʻana.
3.Excellent corrosion kū'ē
Fig. 3 Nā hoʻokolohua ʻino micromotor ma ka condyle femoral a me ka hui cone needle medullary.
Wahi a YY/T 0809.4-2018 maʻamau cyclic loading a ʻaʻohe hemahema i ʻike ʻia, hōʻike nā hopena i kēia huahana he anti-cone micro-motion corrosion performance maikaʻi loa, e hōʻoia i ka palekana o ka hui kuli ma hope o ka hoʻokomo ʻana i ke kino kanaka.
4.Kūleʻa maikaʻi loa i ka ʻaʻahu
Fig. 4 Kiʻi o ka nui o nā kuli prosthesis aahu i nā hopena hoʻokolohua
Wahi a ISO 14243-3: 2014 maʻamau no ka hoʻāʻo hoʻokolohua holoʻokoʻa o ka hui kuli, hōʻike nā hopena i ka maikaʻi o ka lole pale ʻana o ka huahana, e hōʻoia i ka palekana o ka hui kuli ma hope o ke kanu ʻana i ke kino kanaka.
