Dab tsi yog cov khoom tantalum?
Tantalum hlau
Tantalum tuaj yeem ua rau hauv filaments nrog ib txoj kab uas hla ntawm 0.2mm, uas tuaj yeem siv los ua cov tension-resistant sutures uas yooj yim kom tsis muaj menyuam thiab tsis tshua muaj khaus rau cov ntaub so ntswg los siv hauv kev kho mob.
Thaum lub pob tawg tawg lossis tsis muaj kev sib koom ua ke tshwm sim nyob rau sab sauv lossis qis qis lossis lwm qhov chaw, tantalum hlau tuaj yeem ua rau hauv cov ntawv tantalum ntawm cov duab sib txawv thiab ntau thiab tsawg los kho cov kab nrib pleb thiab qhov chaw tsis zoo kom ua tiav kev kho kom zoo.
Tantalum stent
Vim tias tantalum hlau muaj zog ductility, txoj kab uas hla ntawm tantalum hlau ua los ntawm nws tuaj yeem hloov tau zoo dua rau nws cov kev hloov pauv hauv cov hlab ntsha, ua tiav qhov tseeb thiab tso tawm sai. Qee cov kws tshawb fawb tau siv cov hlab ntsha ntawm cov npua me me ua cov qauv tshawb fawb thiab cog cov tantalum hlau stents ua los ntawm tantalum hlau rau hauv lub cev. Tom qab 6 lub hlis ntawm kev soj ntsuam, lawv pom tias tsis muaj kev pom zoo nyob rau hauv cov ntaub so ntswg ntawm lub coronary hlab ntsha tom qab cov stents tau implanted. , thiab cov neointima qhia phasic proliferation hloov.
ntxeem tau tantalum sib koom
Porous tantalum muaj qhov pom tseeb zoo hauv kev siv cov khoom sib koom ua ke. Vim tias tantalum hlau muaj qee qhov elasticity, thaum nws cuam tshuam nrog cov pob txha cortical, nws tuaj yeem tsim me ntsis deformation yam tsis muaj kev tawg. Tsis tas li ntawd, kev sib txhuam coefficient ntawm tantalum hlau yog siab dua li lwm yam Cov ntsiab lus hlau yog siab, yog li kev ruaj ntseg ntawm tantalum hlau tom qab cog yog qhov siab.
Tantalum Coated Khoom
Ntau cov khoom siv hlau tuaj yeem siv rau hauv kev kho mob vim lawv cov khoom tshwj xeeb, tab sis lawv qhov zoo tsis tuaj yeem siv kho mob vim lawv tsis muaj biocompatibility. Tam sim no, peb tuaj yeem pleev xim rau ntawm cov ntaub ntawv hlau no nrog cov hlau zoo heev corrosion-resistant thiab ruaj khov tantalum hlau, tso cai rau cov ntaub ntawv hlau nrog cov khoom tshwj xeeb tab sis thaum chiv tsis tuaj yeem siv kho mob vim tsis muaj biocompatibility yuav rov qab siv tau hauv tsev kho mob.
