Tantalum hlau cov ntaub ntawv yog dav siv nyob rau hauv cov tshuaj kho mob vim lawv siab haum rau txhua yam khoom thiab qaug zog tsis kam thiab yog haum rau implantation ntawm bearing Cheebtsam. Ntau yam khoom siv hlau xws li stainless hlau, titanium-based thiab cobalt-based alloys tau siv dav hauv kev kho mob thiab tau ua tiav qee yam kev kho mob. Txawm li cas los xij, tib neeg ib puag ncig nyuaj tuaj yeem ua rau corrosion ntawm cov ntaub ntawv thiab tso tawm cov tshuaj lom neeg, uas txo qis biocompatibility ntawm cov khoom siv hlau. Tsis tas li ntawd, qhov elastic modulus ntawm qee cov ntaub ntawv hlau txawv dhau ntawm cov ntaub so ntswg ntawm tib neeg lub cev, uas tsis tsim nyog rau kev loj hlob thiab kho cov pob txha tshiab, thiab yooj yim ua rau cov pob txha tawg. Cov xwm txheej tsis zoo no txwv tsis pub siv cov khoom siv hlau ua cov ntaub ntawv biomedical.

Tantalum, kuj yog cov khoom siv hlau, muaj cov khoom siv zoo heev thiab kev tiv thaiv kev qaug zog, yog li nws tau siv dav hauv kev kho mob, tshwj xeeb tshaj yog nyob rau hauv kev kho mob orthopedics, los hloov tib neeg cov pob txha cov ntaub so ntswg los ua lub luag haujlwm ntawm cov kabmob, thiab tau ua tiav qhov tseem ceeb. tshuaj kho mob. Nyob rau hauv cov nqe lus ntawm lub zog, biocompatibility, thiab stability nrog tib neeg cov ntaub so ntswg, tantalum hlau cov ntaub ntawv muaj ntau qhov zoo dua li cov khoom siv cog qoob loo ntawm cov khoom siv hlau, yog li kev txhim kho ntawm tantalum hlau hauv kev kho mob muaj kev cia siab ntau dua.
Cov yam ntxwv ntawm tantalum:
1. Zoo corrosion kuj
Nyob rau hauv chav tsev kub, tantalum yuav tsis hnov mob nrog hydrochloric acid, concentrated nitric acid, los yog txawm aqua regia, thiab yuav tsis zoo tib yam inorganic ntsev corrode nws.
2. Zoo biocompatibility
Tsis zoo li cov khoom siv hlau kho mob, cov ntaub so ntswg loj hlob ntawm tantalum tom qab lub sijhawm cog, ib yam li nws ua rau cov pob txha tiag tiag. Yog li ntawd, tantalum tseem hu ua "metalphile"
3. Zoo elastic modulus
Lub elastic modulus ntawm tantalum nrog ib tug tshwj xeeb pore qauv yog nyob nruab nrab ntawm cov tib neeg cov pob txha tshem tawm thiab cortical pob txha, thiab nws yog tshwj xeeb tshaj yog haum rau cov pob txha hloov, sib koom tes hloov, thiab tib neeg cov ntaub so ntswg filling.
Tantalum khoom:
1. 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 khaus cov ntaub so ntswg rau kev siv hauv kev kho mob.
2. Daim ntawv tantalum
Thaum cov kab nrib pleb thiab pob txha tshwm sim nyob rau sab sauv thiab qis qis lossis lwm qhov chaw lossis tsis muaj kev sib koom ua ke tshwm sim, 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 tsis sib koom ua ke kom ua tiav kev kho kom zoo.
3. Tantalum bracket
Vim lub zog ductility ntawm tantalum hlau, 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, thiab ua tiav qhov tseeb thiab tawm sai. Qee cov kws tshawb fawb tau siv cov hlab ntsha ntawm tus npua me me los ua cov qauv tshawb fawb los cog cov tantalum hlau stent ua los ntawm tantalum hlau rau hauv lub cev. Tom qab ib lub sij hawm ntawm 6 lub hlis ntawm kev soj ntsuam, nws tau pom tias tsis muaj kev tsis lees paub nyob rau hauv lub zos cov ntaub so ntswg ntawm lub coronary hlab ntsha tom qab lub stent tau implanted. , thiab cov neointima pom phasic proliferation hloov.
4. Tantalum-coated khoom
Ntau cov ntaub ntawv hlau tuaj yeem siv rau hauv kev kho mob vim lawv cov khoom tshwj xeeb, tab sis lawv qhov zoo tsis tuaj yeem siv hauv tsev kho mob vim lawv tsis muaj biocompatibility. Tam sim no, peb tuaj yeem pleev xim rau saum npoo ntawm cov ntaub ntawv hlau no nrog tantalum hlau uas muaj zog corrosion kuj thiab ruaj khov, yog li cov ntaub ntawv hlau nrog cov khoom tshwj xeeb uas tsis tuaj yeem siv kho mob vim tias tsis muaj biocompatibility tau rov qab siv dua hauv tsev kho mob.
