I Nhanganyaya
Ibvi prosthesis ine femoral condyle, tibial marrow tsono, yevakadzi marrow tsono, chidimbu chakatemwa uye kugadzirisa wedges, yepakati shaft, tee, tibial plateau tray, condylar mudziviriri, tibial plateau insert, liner, uye kudzora zvikamu.
II Chigadzirwa maitiro emabvi prosthesis
Kugamuchira dhizaini yakasarudzika, iyo bionic dhizaini yenzvimbo yakabatana inogona kuvakazve yakajairika mabvi akabatanidzwa basa;
Iyo biomechanical properties uye elastic modulus ye 3D yakadhindwa bone trabecular interface inonyanya kuenderana nemuviri wemunhu, uye mechanical properties zviri nani;
Iyo porous mesh dhizaini inobatana neimwe kuita inodzima bhonzo yehuchi chimiro neiyo yakanaka biocompatibility yetitanium alloy, iyo inogonesa bhonzo kukura nekukurumidza uye zvakachengeteka.

III Zvakanakira mabvi prosthesis
1.Kuita kwakanaka kwepfupa uye zvinyoro zvinyoro kukura uye kuiswa
Fig. 1 Kukura kwebhonzo mumhuka dzakaiswa bhonzo trabecular structures
Iyo porosity yechigadzirwa ichi inochengetedzwa inopfuura 50%, iyo inopa nzvimbo yakakwana yekuchinjana kwekudya uye oksijeni, inosimudzira kupararira kwesero uye vascularisation ye stem masero, uye inozadzisa tishu ingrowth.Rudzi ruchangozvarwa runokura ruchipinda mugomba repamusoro peprosthesis uye rinopindirana kuita mesh isiri-uniform, iyo yakanyatsobatanidzwa nepamusoro petambo yetitanium pakadzika inosvika 6 mm.Mwedzi mitatu mushure mekuvhiyiwa, matishu inokura ichipinda mumatrix uye inozadza nzvimbo yese ine porous dhizaini, nehupamhi hunosvika 10 mm, uye mwedzi mitanhatu mushure mekuvhiyiwa, iyo yakakura tendon tishu inokura ichipinda muchombo chese, ichinyanya kukosha. kuzadza rate.
2.Excellent kuneta zvinhu
Fig. 2 Kuneta bvunzo mhedzisiro yetibial plateau tray
Iyo tibial ndiro yakaedzwa nemichina maererano neASTM F3334 uye yakaratidza kuneta kwakanyanya kuita ne10,000,000 kutenderera kwekuneta kwekuyedza pasi pe sinusoidal kurodha mamiriro e90N-900N pasina kuputika.
3.Excellent corrosion resistance

Zvinoenderana neYY/T 0809.4-2018 yakajairwa cyclic kurodha uye hapana kukundikana kunowanikwa, mhedzisiro inoratidza kuti chigadzirwa ichi chine yakanakisa anti-cone micro-motion corrosion performance, kuve nechokwadi chekuchengetedzwa kwemabvi akabatanidzwa mushure mekusimwa mumuviri wemunhu.
4.Excellent kupfeka resistance

Zvinoenderana ne ISO 14243-3: 2014 chiyero cheyese yemabvi akabatanidzwa kupfeka kuyedza bvunzo, mhedzisiro inoratidza kuti chigadzirwa chine yakanakisa kupfeka kuramba, kuve nechokwadi chekuchengetedzwa kwebvi rekubatana mushure mekusimwa mumuviri wemunhu.
