Bondo lopangidwa ndi bondo limapangidwa ndi femoral condyle, tibial marrow singano, femoral marrow singano, gawo lodulidwa ndi lokonzedwa, medial shaft, tee, tibial plateau tray, condylar protector, tibial plateau insert, liner, ndi restraining components.
Makhalidwe a bondo lopangira bondo
Pogwiritsa ntchito kapangidwe kake kapadera, kapangidwe ka thupi ka malo olumikizirana amatha kukonzanso ntchito yachibadwa ya malo olumikizirana bondo;
Kapangidwe ka biomechanical ndi elastic modulus ya 3D printed bone trabecular interface zimagwirizana kwambiri ndi thupi la munthu, ndipo kapangidwe ka makina ndi kabwino;
Kapangidwe ka maukonde okhala ndi mabowo kamalumikizana kuti apange kapangidwe ka fupa losasinthika lomwe limagwirizana bwino ndi titaniyamu, zomwe zimathandiza kuti fupalo likule mwachangu komanso motetezeka.
Choteteza cha Femoral Condyle Condyle Tibial Plateau Tray (Kuchokera Kumanzere Kupita Kumanja)
Ubwino wa bondo lopangira
1.Kugwira ntchito bwino kwambiri kwa kukula kwa mafupa ndi minofu yofewa ndi kuyika
Chithunzi 1 Kukula kwa mafupa mwa nyama zomwe zili ndi mafupa okhazikika m'magawo a trabecular
Kuchuluka kwa ma porosity a mankhwalawa kumasungidwa pa 50%, zomwe zimapangitsa kuti pakhale malo okwanira osinthira michere ndi mpweya, zimathandiza kuti maselo azikula komanso kuti maselo oyambira azigwira ntchito bwino, komanso zimapangitsa kuti minofu ikule. Minofu yobadwa kumene imakula mpaka kufika pa porosity pamwamba pa prosthesis ndipo imalumikizana kukhala mesh yosagwirizana, yomwe imagwirizanitsidwa bwino ndi waya wa titaniyamu pamwamba pa 6 mm. Patatha miyezi itatu kuchokera pamene opaleshoni yachitika, minofuyo imakula mpaka kufika pa matrix ndikudzaza malo onse okhala ndi ma porosity, ndi kuya kwa 10 mm, ndipo miyezi 6 pambuyo pa opaleshoni, minofu yokhwima ya tendon imakula mpaka kufika pa porosity yonse, ndi kuchuluka kwakukulu kwa kudzaza.
2. Katundu wabwino kwambiri wotopa
Chithunzi 2 Zotsatira za mayeso a kutopa a tibial plateau tray
Mbale ya tibial idayesedwa ndi makina malinga ndi ASTM F3334 ndipo idawonetsa kutopa bwino kwambiri ndi ma cycle 10,000,000 a mayeso a kutopa pansi pa sinusoidal loading conditions ya 90N-900N popanda kusweka.
3.Kukana dzimbiri kwabwino kwambiri
Chithunzi 3 Kuyesera kwa dzimbiri kwa Micromotor pa femoral condyle ndi medullary needle cone junction
Malinga ndi YY/T 0809.4-2018, kuyika kwa cyclic loading sikunapezeke, zotsatira zake zikuwonetsa kuti mankhwalawa ali ndi mphamvu yabwino kwambiri yolimbana ndi corrosion ya micro-motion micro-motion, kuti atsimikizire kuti bondo limatetezedwa pambuyo poikamo m'thupi la munthu.
4.Kukana bwino kuvala
Chithunzi 4 cha zotsatira za kuyesa kwa zoyeserera zogwirira bondo lonse
Malinga ndi muyezo wa ISO 14243-3:2014 wa mayeso oyesera kuvala bondo lonse, zotsatira zake zikuwonetsa kuti mankhwalawa ali ndi kukana kwabwino kwambiri kuvala, kuti atsimikizire chitetezo cha bondo pambuyo poikamo m'thupi la munthu.
