Kev kho mob Titanium Rods

Ib qho ntawm kev kho mob titanium rods lub ntsiab zoo hauv kev kho mob yog nws lub zog siab-rau-qhov sib piv. Cov kws phais mob thiab lwm tus kws kho mob yuav pom tias nws yooj yim dua los ua cov txheej txheem ilv nrog cov khoom siv kho mob titanium vim tias nws yog ze li ib nrab ntawm lub teeb thiab muaj zog tib yam li cov khoom siv hlau.

Osseointegration yog ib qho phenomenon uastitaniumua rau nws muaj peev xwm rau cov pob txha thiab cov ntaub so ntswg mus rau kev cog hniav los yog kev kho mob implants, khov kho anchoring nws nyob rau hauv qhov chaw.

Qhov tseem ceeb, tib neeg lub cev tsis lees txais titanium pas nrig kho mob vim tias lawv yog biocompatible. Lawv kuj tsis yog-ferromagnetic, yog li MRI thiab NMRI scans tseem tuaj yeem ua tau zoo rau cov neeg mob nrog titanium implants.

1. Terminology

1.1 Txhais cov ntsiab lus tshwj xeeb rau tus qauv ASTM F136:

1.1.1 Beta transit, n-qhov kub tsawg kawg nkaus uas lub alpha ntxiv rau beta theem tuaj yeem hloov mus rau 100% beta theem.

1.1.2 ntau, n- tag nrho cov khoom zeb uas tsim los ntawm ib lub tshav kub nyob rau hauv tib lub sijhawm ntawm qhov tseem ceeb tib lub sijhawm.

2. Khoom siv thiab tsim khoom

2.1 ntau yam titanium zeb cov khoom uas muaj nyob rau hauv cov lus qhia no feem ntau yog tsim nrog cov pa forging thiab dov khoom pom nyob rau hauv thawj ferrous thiab nonferrous nroj tsuag. Cov hlau feem ntau yog ntau yam melted nyob rau hauv lub cub tawg (nrog rau lub cub tawg xws li plasma arc thiab electron beam) ntawm ib hom conventionally siv rau reactive hlau.

2.2 Tiav- Cov khoom zeb tuaj yeem muab rau cov chaw tsim khoom cog raws li cov khoom siv descaled lossis pickled abrasively blasted, tshuaj milled, hauv av, machined, tev, polished, ua ke ntawm cov haujlwm no, lossis raws li tus neeg yuav khoom tau teev tseg. Ntawm billets, tuav, daim hlau thiab forgings, nws yog tso cai rau tshem tawm me me deg imperfections los ntawm kev sib tsoo yog hais tias tus resultant sear ua tau raws li qhov yuav tsum tau ntawm qhov ntev thiab nto tiav ntawm qhov specification.

2.3 Qhov xwm txheej-Cov khoom siv yuav tsum tau muab tso rau hauv qhov chaw ua haujlwm txias lossis ua haujlwm txias. Cov khoom siv kho tshuab rau cov xwm txheej uas tsis yog cov teev hauv cov lus 1 thiab cov lus 1 yuav raug tsim los ntawm kev pom zoo ntawm tus neeg muag khoom thiab tus neeg yuav khoom.

Titanium pas nrig yog ib qho kev xaiv nrov rau kev cog qoob loo rau ntau yam laj thawj:

Biocompatibility: kev kho mob titanium rods yog biocompatible, uas txhais tau hais tias nws tsis hnov ​​​​mob rau tib neeg lub cev thiab tsis muaj tshuaj lom los yog tsim kev puas tsuaj rau cov ntaub so ntswg. Qhov no ua rau nws muaj kev nyab xeeb khoom siv rau hauv kev kho mob cog.

Corrosion kuj: titanium pas nrig kho mob yog heev resistant rau corrosion, uas txhais tau hais tias nws muaj peev xwm tiv taus lub corrosive ib puag ncig ntawm lub cev kua thiab tsis tshua muaj kev puas tsuaj los yog deteriorate nyob rau hauv lub sij hawm.

Lub zog thiab ruaj khov: ASTM F136 Titanium pas nrig yog cov khoom siv muaj zog thiab ruaj khov, uas txhais tau hais tias nws tuaj yeem tiv taus kev ntxhov siab thiab kev siv txhua hnub hauv tib neeg lub cev.

Lub teeb yuag: Titanium cov pas nrig kho mob yog cov khoom siv hnyav, uas ua rau nws yooj yim dua rau cov neeg mob nqa cov khoom cog thiab txo qhov kev pheej hmoo ntawm cov teeb meem los yog tsis xis nyob.

Kev pom zoo sib xws: qib kev kho mob titanium pas nrig yog sib haum nrog kev kho mob cov tswv yim xws li X-rays thiab MRI, uas ua rau nws yooj yim dua rau cov kws kho mob saib xyuas qhov cog thiab qhov teeb meem ib puag ncig.
