Xa uphatiente onemiphumela yemiphefumulo yekhondrithi yasebenza kabusho emuveni wokuthola i-joint yekhondrithi engenayo, kukhona isibonelo sokuphela kweziteknoloji zokwenza okuphambene. Kusimini lwemigwa yemqamayo, izikhishwa zokwenza i-Mill-turn, ngazo zonke izindlela eziphambene, zikhona isiqinisekiso esikhulu ekhuthazeni kakhulu kwebhodhi nokuthuthukisa iziteknoloji.
Imiphumela Elinganayo Kukwenza Kwemigwa Yemqamayo
Imigwa yemqamayo yokudokotela idlaya kakhulu kwebhodhi nokuhlele kwebhodhi, kubophelela ukwenza okuphezulu. Imigwa felokhondrithi nezilayezo zokuphakama kufanele kufake kahle nezibhodi kanti nezinhlelo eziphambene nezinhlelo zokusebenza.
Izindlela zokusebenzisa izililo eziyisisekelo nezililo ze-cobalt-chromium-molybdenum zifaka imiphumela yokuvumelana kwabiocompatibility kodwa zinezinkinga eziphakeme kumachining. Lezi zililo, ezichaziwe ngokukhulu kwez strength nez toughness, zange zibangela izinkinga ezifanayo nezindlela zokulayela okuphezulu kanye nokulahleka okuphansi kwezindlela zokucima, kubangelwa ukuthi kunezidingo eziphakeme kwiindlela zokusebenza. Ngokudla, izinto zokulungisa izinto zokugcina izindlela ezinhlelweni zokugcina- njengokuzingca kwamagcina amanhlanje nezindlela zokugcina izindlela zokugcina- kudinga ukuthi izindlela zokusebenza zibe yimali micrometer.
Izindlela zokusebenzisa izindlela zokusebenza zilandela izindlela eziningi zokugcina, okungatholakali kodwa kungenzeka ukuthi kuthathwe amaphutha amaningi, akwazi ukufanipha izidingo zokuthula kwezindlela zokulungisa. Ukuthuthwa kwezindlela zokusebenza kwiindlela zokusebenza kuthuthwe kona izidingo lezi.
Izinkinga Ezinhle Zokusebenzisa Iindlela Zokusebenza
Izikhishwa zokwenza izindlela zokuhlinzela ukuchithwa okuningi kweziciro kanye nezinye izindlela zokuhlinzela—kanye nokuhlinzela, ukubhola, nokubhola—kunikeza amandla ukuba kube yisicelo esiyahlwa okanye yonke into ehlwa ngokugcina ngokugcina okunye. Lokhu kwenza kabusho amaphoyinti athiwa ngokugcina okuningi. Iinkqubo zabo zokuhlinzela ngokuvumelanayo zenze ukwenza kwezinye izicaba ezinhlelweyo, ekunikeza ukuba izicaba eziphambene kwezixhobo zokulungisa izifo zingasebenzi njengamathuba okwenyelwa.
Vumela izicaba zokulungisa ikoti yekoti: i-femoral condyle inezicaba ezinhlelweyo ezifanele ukufuna kwaye zifunakale ukuba zifitile kakhulu kwiibhonyi zomntu. Ngokwenza ukuvumelana ngokuvumelana, izikhishwa zokuhlinzela i-mill-turn zenze ukwenza kwezicaba ezinhlelweyo ngokwenyanga enye, ukufikelela kwi-accuracy yoku-±0.005mm kunye nesurface roughness ye-Ra 0.8μm okanye phezulu—kunikeza ubuncinane obuphakeme kwekuthiwa ngemva kokuchithwa.
Kwesivumo sezingeniso, izinkampani zokwenza izinto ziqukile ngemigomo ye-CNC ebalulekileyo engaguqula izindlela zokukhishwa (njengokukhishwa kwezivumo kanye nokukhishwa komkhawulo) ngokwesivumo sezingeniso ezahlukene. Lokhu kuhle kuthikitha izinkinga zokukhishwa kwezingeniso ezikhishwayo kangaka njengamakhemikhali we-titanium. Ngokwesibonelo, ubukhulu bendawo yokukhishwa kanye nezinhlobo zokuxazulula eziphumelelayo zixazulula ukuphumelela kwenqanawa, kubangela ukunciphisa kakhulu kwesivumo sezingeniso.
Ukuqhuba kwezibonelo esiboneni sokugcinwa kwemali
Isisekelo sezingcamathini zokukhishwa kanye nezinkinga zokwenza izinto zokuqinisekisa ukuthuthukwa kwalokhu kanye nokuthuthukwa kwebhizinisi yezinto zokugcinwa kwemali. Ngokuthiwa kanye nezinhlobo zokuprinta i-3D kanye nezinkinga zokukhishwa, abadokotela bakhona ukwenza izinto zokugcinwa kwemali ngezinga elingenhla ngokushintshela izinto zokugcinwa kwemali ngokushintshela izinto zokugcinwa kwemali.
Okoku, ukuprintwa kwe-3D usebenzisa ukwenza amadoda wezimalo ezinhlosoke, ebe yizindlela zokubhala ngokucophelela ngokusebenzisa izindawo zokubhala. Le ndlela ikhomba ukuthi kuthunyelwe ngempela phakathi kwezimalo nezithi zomuntu wokugcinwa futhi kuthunyelwe nezimithetho eziphathelene nezobuchwephesha. Le ndlela yokwenza okuhlangene nezinhloso yasebenzisa kwezinhawu zokubhinda futhi kwezinyathelo zokulungisa izicwele, kakhulu ukuqinisekisa ukuba izinyathelo zokuchitha ziyaphumelela futhi kahle kakhulu kwezimalo emva kwezinyathelo zokuchitha.
