Uvavanyo lwe-Biocompatibility ngokwe-ISO 10993 luyafuneka ngokusekwe kuhlelo lwesixhobo kunye nohlobo loqhagamshelwano. Kwiimarike ze-EU, ukuthotyelwa kwe-EU MDR 2017/745 kunye ne-ISO 13485: 2016 kunyanzelekile.
Ingaba ukucocwa kwesitampu segumbi kuchaphazela njani iindleko zamalungu e-titanium yonyango?
Isitampu esicocekileyo segumbi songeza malunga ne-15-30% kwixabiso lemveliso yecandelo ngalinye xa kuthelekiswa neemeko ezingqongileyo zemveliso. Iindleko ezongezelelekileyo ziquka ukucoceka kwegumbi eliphezulu, izixhobo ezikhethekileyo (oomatshini bokushicilela be-servo, iindawo ezivalelweyo), imigaqo yokucoca ephuculweyo, ukunxiba nokubeka iliso, kunye namaxwebhu angqongqo. Nangona kunjalo, kumacandelo okufakelwa kwebakala, ukuveliswa kwegumbi elicocekileyo kunyanzelekile - iindleko zokungaphumeleli okunxulumene nokungcoliseka (ukhumbula, ukwenzakala kwesigulane, isenzo sokulawula) kudlula kakhulu iindleko ezikhulayo zokuvelisa.
Kukuphi ukugqitywa komphezulu ofunekayo ukuze kufakwe isitampu se-titanium orthopedic implants?
Iimfuno zokugqiba umphezulu zixhomekeke kwindawo yokufakelwa kwethambo. Imiphezulu egudileyo (Ra ≤ 0.8 µm) icaciswe kwiindawo ezingadibanisi nethambo ukuze kuncitshiswe ukucaphuka kwezicubu ezithambileyo. Umphezulu odibana namathambo ngokuqhelekileyo ufuna uburhabaxa obulawulwayo (Ra 1–5 µm) obuphunyezwe ngokuqhushumba kwegrit okanye ukucholwa kweplasma ukukhuthaza ukuhlangana kwe-osseo. Uninzi lwezifakelo zamathambo zanamhlanje zikwabonisa iingubo ze-hydroxyapatite (HA) kwindawo yoqhagamshelwano lwamathambo ukukhawulezisa ukulungiswa kwebhayoloji. Yonke imiphezulu kufuneka igqitywe kwaye ingabi nazingcolisi ezifakwe ngaphakathi, ziqinisekiswe nge-SEM kunye nohlalutyo lwe-XRF.
Isiphelo: Ukwenza ukhetho oluLungileyo lweProjekthi yakho yeSitampu sezoNyango
Isigqibo phakathi kwe-titanium kunye nesitampu sensimbi engenasici kwizixhobo zonyango asifane siqonde. Ifuna ukulungelelaniswa kweemfuno zeklinikhi, ukuba nokwenzeka kwemveliso, isicwangciso solawulo, kunye neendleko ezipheleleyo zobunini.
Khetha i-titanium xa: i-biocompatibility iyona nto ibalulekileyo, isixhobo sifakwe ngokusisigxina, imiba yobunzima, okanye ukuhambelana kwe-MRI ayinakuxoxisana. Yamkela iindleko eziphezulu zokuvelisa kunye nexesha elide lophuhliso njengotyalo-mali ekusebenzeni kweklinikhi.
Khetha insimbi engenasici xa: isixhobo sisixhobo sotyando okanye ukufakelwa kwethutyana, umthamo wemveliso uphezulu, iijiyometri ezintsonkothileyo zifuna ukwakheka okuphezulu, okanye imiqobo yeendleko iqinile. Sebenzisa izibonelelo zokwenziwa kwentsimbi kunye nesikhokelo esibanzi solawulo.
Kuzo zombini ezi meko, iqabane kunye nomthengisi wesitampu onamava kukwenziwa kwesixhobo zonyango, isiqinisekiso se-ISO 13485, kwaye sixhotyiswe ngolawulo lwenkqubo kunye neenkqubo zomgangatho zifuna ungeniso lwakho lolawulo.
