Izifakelo zoTshintsho lweTitanium Total Knee Joint ezikumgangatho ophezulu
Iimpawu zeTitanium zeDolo Implants
Izifakelo zokufakelwa kwe-titanium edolweni ezikumgangatho ophezulu
Izinto ezifakelwe edolwenikwaziwa njengei-prosthesis yamadolo, zizixhobo zonyango ezisetyenziselwa ukuthatha indawo yamalungu edolo onakeleyo okanye agulayo. Zisetyenziswa rhoqo ukunyanga izigulana ezine-arthritis enzima, ukwenzakala, okanye ezinye iimeko ezibangela iintlungu ezingapheliyo zamadolo kunye nokuhamba okulinganiselweyo. Injongo ephambili yokufakelwa kwamalungu edolo kukunciphisa iintlungu, ukubuyisela ukusebenza, kunye nokuphucula umgangatho wobomi jikelele kwizigulana ezine-degeneration enzima yamalungu edolo.
Icandelo le-femoral le-ukutshintshwa kwedolosisiqwenga sesinyithi okanye seseramikhi esithatha indawo yesiphelo sethambo lethanga (i-femur) kwijoyinti yedolo. Sinesimo esifana nokwakheka kwendalo kwethambo ukuze lingene kakuhle kwijoyinti. Inxalenye yejoyinti idla ngokuncamathiselwa kwithambo ngesamente ekhethekileyo okanye ngendlela yokucinezela ekhuthaza ukukhula kwamathambo ajikeleze i-implant.
Ngexeshaukutshintshwa kwedoloEmva kotyando, ugqirha uza kwenza utyando edolweni aze asuse inxalenye eyonakeleyo ye-femur. Ugqirha uza kulungiselela ithambo ukuze lifumane i-femoral component implant. I-femoral component iza kubekwa kwaye iqiniswe endaweni yayo kusetyenziswa isamente yethambo okanye indlela yokufakela i-press-fit. Nje ukuba i-femoral component ibekwe endaweni yayo, ugqirha uza kuyivala i-incision kwaye isigulane siza kuqala inkqubo yokuchacha. Emva kotyando, izigulane ziya kufuneka zithathe inxaxheba kwimithambo yonyango lomzimba ukunceda ukuqinisa idolo nokukhuthaza ukuphiliswa. Emva kweenyanga ezimbalwa zokuvuselelwa, izigulane zihlala zilindele ukuba idolo lizive lingcono kakhulu kwaye libe nokusebenza okuphuculweyo. Nangona kunjalo, kubalulekile ukulandela nayiphi na imiyalelo emva kotyando enikezelwa ngugqirha ukuqinisekisa ukuphiliswa nokuchacha okufanelekileyo.
Kuphephe ukuxhomekeka kwiimpawu ezintathu
1. Uyilo lweeradiyumu ezininzi lubonelelainkululeko yokujika kunye nokujikeleza.
2. Uyilo lwe-radius ehlayo ye-J curve femoral condyles lunokuthwala indawo yoqhagamshelwano ngexesha lokujika okuphezulu kwaye luphephe ukumba ngaphakathi.
Uyilo olucekeceke lwePOST-CAM lufezekisa i-osteotomy encinci ye-intercondylar ye-PS prosthesis. I-retained anterior continuous bone bridge inciphisa umngcipheko wokuqhekeka.
Uyilo olufanelekileyo lwe-trochlear groove
I-patellatrajectory eqhelekileyo yi-S shape.
● Nqanda ukuthambekela kwe-patella medial xa ugoba kakhulu, xa idolo kunye ne-patella zinamandla okucheba kakhulu.
● Musa ukuvumela umgca ophakathi wendlela yepatella.
1. Iiwedges ezihambelanayo
2. Udonga olusecaleni oluphakathi kwekhondila olucoliweyo kakhulu luyakuphepha ukukrala emva kokugruzuka.
3. Ibhokisi evulekileyo ye-intercondylar ithintela ukukrala kwe-post top.
Ukugoba i-155 degree kungabakufezekisiwengobuchule obuhle botyando kunye nokuzilolonga okusebenzayo
Iikhowuni zokuprinta ze-3D zokugcwalisa iziphene ezinkulu ze-metaphyseal ngesinyithi esinemingxuma ukuvumela ukukhula.
Iimpawu zokutshintshwa kwamalungu edolo
Irheumatoid arthritis
I-arthritis emva kwe-traumatic, i-osteoarthritis okanye i-arthritis ewohlokayo
Ukungasebenzi kakuhle kwe-osteotomies okanye ukutshintshwa kwe-unicompartmental okanye ukutshintshwa kwedolo elipheleleyo
