Orthopedic titanium knee joint replacement prosthesis
Ibvi ndiro mubatanidzwa mukuru kwazvo wemuviri wemunhu. Inobatanidza femur yako kune tibia yako. Inokubatsira kumira, kufamba uye kuchengetedza chiyero chako. Ibvi rako rinewo shwashwa, senge meniscus, uye ligaments, kusanganisira anterior cruciate ligament, yepakati cruciate ligament, anterior cruciate ligament, uye anterior cruciate ligament.
Nei tichidaibvi rakabatana kutsiva?
Chikonzero chinonyanya kukoshakuvhiyiwa kwekutsiva ibvindeyekubvisa marwadzo anokonzerwa nearthritis. Vanhu vanoda kuvhiyiwa kwekutsiva mabvi vane dambudziko rekufamba, kukwira masitepisi uye kusimuka kubva pazvigaro. Chinangwa chebvi rekugadzirisa prosthesis ndechekugadzirisa pamusoro penzvimbo yakakanganiswa yemabvi uye kuderedza marwadzo emabvi asingagoni kudzorwa nemamwe marapirwo. Kana chikamu chete chebvi chikakuvadzwa, chiremba anovhiya anogona kazhinji kutsiva chikamu ichocho. Izvi zvinonzi partial knee replacement. Kana mubatanidzwa wose uchida kutsiviwa, kuguma kwefupa remukadzi uye tibia kunoda kugadziriswa, uye mubatanidzwa wose uchada kuonekwa. Izvi zvinonzikutsiva ibvi rose (TKA). Femur bone uye tibia machubhu akaomarara ane mukati munyoro mukati. Kuguma kwechikamu chekugadzira chinopinzwa mukati mepakati pepfupa.
Dzivisa pendency nezvinhu zvitatu
1.The multi-radius design inopa
s rusununguko rwekuchinjika uye kutenderera.
2.Magadzirirwo ekuderera kweradius yeJ curve femoral condyles inogona kutakura nzvimbo yekubatana panguva yekukwirira kwepamusoro uye kudzivisa kuisa kuchera.
Iyo yakapfava dhizaini yePOST-CAM inowana iyo diki intercondylar osteotomy yePS prosthesis. Iyo yakachengetwa anterior inoenderera bhonzo bhiriji inoderedza njodzi yekutyoka.
Yakanaka trochlear groove dhizaini
Iyo yakajairika patellatrajectory ndeye S chimiro.
● Kudzivirira patella medial bias panguva yekukwirira kwepamusoro, apo mabvi akabatanidzwa uye patella zvinotakura simba rekugera zvakanyanya.
● Usabvumira patella trajectory cross centre line.
1.Matchable wedges
2.Iyo yakakwenenzverwa intercondylar side wall inodzivirira post abrasion.
3.Iyo yakazaruka intercondylar bhokisi inodzivirira abrasion ye post top.
Flexion 155 degree inogona kuvakubudiriranemaitiro akanaka ekuvhiya uye kurovedza muviri
3D kudhinda makoni kuzadza hombe metaphyseal defects ne porous simbi kubvumira ingrowth.
Knee Joint Replacement Zviratidzo
Rheumatoid arthritis
Post-traumatic arthritis, osteoarthritis kana degenerative arthritis
Osteotomies yakakundikana kana unicompartmental kutsiva kana kutsiva ibvi rose
