Isingeniso
I-prosthesis yamadolo iqukethe i-femoral condyle, inaliti ye-tibial marrow, inaliti ye-femoral marrow, ingxenye enqunyiwe kanye nama-adjustment wedges, i-medial shaft, i-tee, i-tibial plateau tray, i-condylar protector, i-tibial plateau insert, i-liner, kanye nezingxenye zokuvimbela.
II Izici zomkhiqizo we-knee prosthesis
Ngokwamukela umklamo oqondene nomuntu siqu, umklamo we-bionic wobuso obuhlangene ungakha kabusha umsebenzi ojwayelekile wokuhlangana kwedolo;
Izakhiwo ze-biomechanical kanye ne-modulus elastic ye-3D printed bone trabecular interface zihambisana kakhulu nomzimba womuntu, futhi izakhiwo ze-mechanical zingcono;
Isakhiwo se-mesh esinezimbobo sixhumana sodwa ukuze sakhe isakhiwo se-honeycomb esingenaso ithambo esihambisana kahle ne-titanium alloy, okwenza ithambo likhule ngokushesha nangokuphephile.

III Izinzuzo ze-prosthesis yamadolo
1. Ukusebenza okuhle kakhulu kokukhula kwezicubu ezithambile kanye nokufakwa kwamathambo
Isithombe 1 Ukukhula kwamathambo ezilwaneni ezinezakhiwo ze-trabecular zamathambo ezifakiwe
I-porosity yalo mkhiqizo igcinwa ingaphezu kuka-50%, okunikeza isikhala esanele sokushintshana kwezakhamzimba nomoya-mpilo, kukhuthaza ukwanda kwamaseli kanye nokufakwa kwemithambo yegazi kwamaseli okuqala, futhi kufinyelele ekukhuleni kwezicubu. Izicubu ezisanda kuzalwa zikhula zibe yimbobo ebusweni be-prosthesis bese zihlangana zibe yi-mesh engalingani, ehlanganiswe ngokuqinile nengqimba ephezulu ye-titanium wire ekujuleni okungaba ngu-6 mm. Ezinyangeni ezi-3 ngemva kokuhlinzwa, izicubu zikhula zibe yi-matrix futhi zigcwalisa yonke indawo yesakhiwo esinezimbobo, ngokujula okungaba ngu-10 mm, kanti ezinyangeni ezi-6 ngemva kokuhlinzwa, izicubu ze-tendon ezivuthiwe zikhula zibe yisakhiwo sonke esinezimbobo, ngesilinganiso sokugcwalisa esibaluleke kakhulu.
2. Izakhiwo ezinhle kakhulu zokukhathala
Isithombe 2 Imiphumela yokuhlolwa kokukhathala kwethreyi ye-tibial plateau
Ipuleti le-tibial lihlolwe ngomshini ngokwe-ASTM F3334 futhi labonisa ukusebenza kahle kokukhathala ngemijikelezo eyi-10,000,000 yokuhlolwa kokukhathala ngaphansi kwezimo zokulayisha ze-sinusoidal ze-90N-900N ngaphandle kokuqhekeka.
3. Ukumelana nokugqwala okuhle kakhulu
Isithombe 3 Ukuhlolwa kokugqwala kwe-Micromotor ekuxhumaneni kwe-femoral condyle kanye ne-medullary needle cone
Ngokusho kwe-YY/T 0809.4-2018 ukulayisha okuvamile okujikelezayo futhi akukho ukwehluleka okutholakalayo, imiphumela ikhombisa ukuthi lo mkhiqizo unamandla amahle kakhulu okulwa nokugqwala kwe-micro-motion anti-cone, ukuqinisekisa ukuphepha kwejoyinti ledolo ngemva kokufakwa emzimbeni womuntu.
4.Ukumelana okuhle kakhulu kokugqokwa
Isithombe 4 semiphumela yokuhlola ukugqokwa kwe-prosthesis yamadolo ephelele
Ngokusho kwe-ISO 14243-3: Izinga elijwayelekile lika-2014 lokuhlolwa kokuhlolwa kokugqoka kwamalunga edolo okuphelele, imiphumela ikhombisa ukuthi umkhiqizo unokumelana okuhle kakhulu nokuguguleka, ukuqinisekisa ukuphepha kwelunga ledolo ngemva kokufakwa emzimbeni womuntu.
