I Intshayelelo
I-prosthesis yamadolo iqukethe i-condyle ye-femoral, inaliti ye-tibial marrow, inaliti ye-femal marrow, isahlulo esincinciweyo kunye ne-wedges yokulungelelanisa, i-shaft medial, i-tee, i-tibial plateau tray, i-condylar protector, i-tibial plateau insert, i-liner, kunye namacandelo okuthintela.
II Iimpawu zeMveliso yeprosthesis yamadolo
Ukwamkela uyilo lomntu, uyilo lwe-bionic yendawo edibeneyo inokwakha kwakhona umsebenzi odibeneyo wamadolo;
Iimpawu ze-biomechanical kunye ne-elastic modulus ye-3D eprintiweyo i-bone trabecular interface ihambelana ngakumbi nomzimba womntu, kwaye iimpawu zomatshini zingcono;
Isakhiwo se-mesh ene-porous sidibanisa enye kwenye ukuze senze isakhiwo se-honeycomb se-honeycomb kunye ne-biocompatibility efanelekileyo ye-titanium alloy, eyenza ukuba ithambo likhule ngokukhawuleza kwaye likhuselekile.

III Iinzuzo zeprosthesis yamadolo
I-1.Ukusebenza ngokugqwesileyo kwamathambo kunye nokukhula kwezicubu ezithambileyo kunye nokufakwa
Umzobo 1 Ukukhula kwamathambo kwizilwanyana ezifakwe kwi-trabecular structures
I-porosity yale mveliso igcinwe ngaphezu kwe-50%, enika indawo eyaneleyo yokutshintshiselana kwezondlo kunye ne-oksijini, ikhuthaza ukwanda kweeseli kunye ne-vascularisation yeeseli ze-stem, kwaye ifezekisa i-ingrowth yezicubu.Izicubu ezisanda kuzalwa zikhula kwi-pore ye-prosthesis surface kwaye zidibanise kwi-mesh engekho-uniform, edityaniswe ngokuqinileyo kunye nomgangatho ophezulu wocingo lwe-titanium kubunzulu obumalunga ne-6 mm.Kwiinyanga ezi-3 emva kotyando, izicubu zikhula zibe yi-matrix kwaye zizalise yonke indawo yesakhiwo se-porous, kunye nobunzulu obumalunga ne-10 mm, kunye neenyanga ezi-6 emva kotyando, izicubu ze-tendon ezikhulileyo zikhula zibe yinkqubo yonke ene-porous, enokubaluleka ngakumbi. izinga lokuzalisa.
2.Iimpawu zokudinwa ezigqwesileyo
Umzobo we-2 Iziphumo zovavanyo lokukhathala kwetreyi ye-tibial plateau
I-plate ye-tibial yavavanywa ngomatshini ngokwe-ASTM F3334 kwaye yabonisa ukusebenza kakuhle kokukhathala kunye nemijikelezo ye-10,000,000 yokuvavanya ukukhathala phantsi kweemeko zokulayisha i-sinusoidal ye-90N-900N ngaphandle kokuqhekeka.
3.Ukumelana nokugqwesa okugqwesileyo
Umzobo 3 Imifuniselo ye-Micromotor corrosion kwi-femoral condyle kunye ne-medullary inaliti ye-cone junction.
Ngokutsho kwe-YY / T 0809.4-2018 yokulayisha i-cyclic esemgangathweni kwaye akukho kusilela kufunyenwe, iziphumo zibonisa ukuba le mveliso ine-anti-cone micro-motion corrosion performance encomekayo, ukuqinisekisa ukhuseleko lwamadolo emva kokufakelwa emzimbeni womntu.
4.Ukumelana nokunxiba okugqwesileyo
Umzobo we-4 Umfanekiso weziphumo zovavanyo zeprosthesis epheleleyo yamadolo
Ngokutsho kwe-ISO 14243-3: umgangatho we-2014 wovavanyo olupheleleyo lwe-knee joint wear experiment, iziphumo zibonisa ukuba imveliso inokumelana okugqwesileyo kokugqoka, ukuqinisekisa ukhuseleko lwedolo elidibeneyo emva kokufakelwa emzimbeni womntu.
