Intshayelelo
I-knee prosthesis iqulethe i-femoral condyle, inaliti ye-tibial marrow, inaliti ye-femoral marrow, i-segment equnyiweyo kunye nee-adjustment wedges, i-medial shaft, i-tee, i-tibial plateau tray, i-condylar protector, i-tibial plateau insert, i-liner, kunye nezinto ezithintelayo.
II Iimpawu zemveliso ye-knee prosthesis
Ngokwamkela uyilo olulungiselelwe wena, uyilo lwebhayoloji lomphezulu odibeneyo lunokwakha kwakhona umsebenzi oqhelekileyo wokudibanisa idolo;
Iimpawu ze-biomechanical kunye ne-elastic modulus ye-3D printed bone trabecular interface zihambelana ngakumbi nomzimba womntu, kwaye iimpawu ze-mechanical zingcono;
Isakhiwo se-mesh esineembobo sidibana ukuze senze isakhiwo se-honeycomb esine-cancellous bone esihambelana kakuhle ne-titanium alloy, esenza ukuba ithambo likhule ngokukhawuleza nangokukhuselekileyo.

III Iingenelo ze-dolo prosthesis
1. Ukusebenza kakuhle kakhulu kokukhula kwamathambo kunye nezicubu ezithambileyo kunye nokufakwa
Umzobo 1 Ukukhula kwamathambo kwizilwanyana ezinezakhiwo ze-trabecular zamathambo ezifakelweyo
Ubume bombhobho bale mveliso bugcinwa bungaphezulu kwe-50%, nto leyo enika indawo eyaneleyo yokutshintshiselana kwezondlo kunye neoksijini, ikhuthaza ukwanda kweeseli kunye nokusasazwa kwemithambo yegazi kwiiseli ze-stem, kwaye ifezekisa ukukhula kwezicubu. Izicubu ezisandul' ukuzalwa zikhula zibe yimbobo yomphezulu we-prosthesis kwaye zidibene zibe yi-mesh engalinganiyo, edityaniswe ngokuqinileyo nomaleko ongaphezulu we-titanium wire kubunzulu obuyi-6 mm. Kwiinyanga ezi-3 emva kotyando, izicubu zikhula zibe yi-matrix kwaye zizalise yonke indawo yesakhiwo esineembobo, ngobunzulu obuyi-10 mm, kwaye kwiinyanga ezi-6 emva kotyando, izicubu ze-tendon ezivuthiweyo zikhula zibe yisakhiwo sonke esineembobo, ngesantya sokuzalisa esibaluleke ngakumbi.
2.Iipropati zokudinwa ezigqwesileyo
Umfanekiso 2 Iziphumo zovavanyo lokudinwa kwitreyi yethafa le-tibial
Ipleyiti ye-tibial ivavanywe ngoomatshini ngokwe-ASTM F3334 kwaye ibonise ukusebenza kakuhle kokudinwa ngemijikelo eyi-10,000,000 yovavanyo lokudinwa phantsi kweemeko zokulayisha ze-sinusoidal ze-90N-900N ngaphandle kokuqhekeka.
3. Ukumelana nokugqwala okugqwesileyo
Umfanekiso 3 Uvavanyo lwe-Micromotor corrosion kwi-femoral condyle kunye ne-medullary needle cone junction
Ngokwe-YY/T 0809.4-2018, ukulayisha okuqhelekileyo okujikelezayo kwaye akukho kusilela kufunyenweyo, iziphumo zibonisa ukuba le mveliso inamandla okugqwala okuchasene ne-cone micro-motion corrosion, ukuqinisekisa ukhuseleko lwedolo emva kokufakelwa emzimbeni womntu.
4.Ukumelana nokuguguleka okugqwesileyo
Umfanekiso 4. Umfanekiso weziphumo zovavanyo lokunxiba i-prosthesis yedolo iyonke
Ngokwe-ISO 14243-3: umgangatho ka-2014 wovavanyo lokunxiba kwamadolo ngokupheleleyo, iziphumo zibonisa ukuba imveliso inokumelana nokuguguleka okuhle kakhulu, ukuqinisekisa ukhuseleko lwamadolo emva kokufakelwa emzimbeni womntu.
