Cov txiaj ntsig ntawm titanium ua cov khoom siv orthopedic implant

Qhov zoo ntawm titanium ua cov khoom siv orthopedic implant feem ntau yog pom tseeb hauv cov hauv qab no:

1, Kev sib haum xeeb ntawm lub cev:

Titanium muaj kev sib raug zoo nrog tib neeg cov ntaub so ntswg, tsis tshua muaj kev cuam tshuam nrog tib neeg lub cev, tsis muaj tshuaj lom thiab tsis muaj hlau nplaum, thiab tsis muaj kev phiv tshuaj rau tib neeg lub cev.

Qhov kev sib raug zoo zoo no tso cai rau titanium implants kom muaj nyob hauv tib neeg lub cev ntev yam tsis ua rau muaj kev tsis lees paub meej.

2, Cov khoom siv kho tshuab:

Titanium muaj cov yam ntxwv ntawm lub zog siab thiab qis elastic modulus, uas tsis tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv kho tshuab, tab sis kuj nyob ze rau elastic modulus ntawm cov pob txha tib neeg ntuj.

Cov khoom siv kho tshuab no pab txo qhov cuam tshuam ntawm kev tiv thaiv kev ntxhov siab thiab ua rau tib neeg cov pob txha loj hlob thiab kho tau zoo dua.

Lub modulus elastic ntawmtitanium hlauyog qis. Piv txwv li, lub elastic modulus ntawm titanium ntshiab yog 108500MPa, uas yog ze rau lub pob txha ntuj ntawm tib neeg lub cev, uas yog

ua rau pob txha teeb tsa thiab txo qhov cuam tshuam ntawm kev ntxhov siab ntawm cov pob txha rau ntawm cov implants.

3, Kev tiv thaiv corrosion:

Titanium alloy yog cov khoom siv inert biologically nrog kev tiv thaiv corrosion zoo hauv qhov chaw ib puag ncig ntawm tib neeg lub cev.

Qhov kev tiv thaiv corrosion no ua kom ntseeg tau tias lub sijhawm ntev ntawm titanium alloy implants hauv tib neeg lub cev ruaj khov thiab yuav tsis ua rau lub cev ib puag ncig ntawm tib neeg lub cev puas tsuaj vim yog corrosion.

4, Sib dua:

Qhov ceev ntawm titanium alloy yog qhov tsawg, tsuas yog 57% ntawm cov hlau tsis xeb.

Tom qab muab cog rau hauv tib neeg lub cev, nws tuaj yeem txo qhov hnyav ntawm tib neeg lub cev, uas yog qhov tseem ceeb rau cov neeg mob uas xav tau hnav cov khoom cog rau lub sijhawm ntev.

5, Tsis yog hlau nplaum:

Titanium alloy tsis yog hlau nplaum thiab tsis cuam tshuam los ntawm cov teb hluav taws xob thiab cua daj cua dub, uas yog qhov zoo rau kev nyab xeeb ntawm tib neeg lub cev tom qab cog rau hauv.

6, Kev sib koom ua ke ntawm pob txha zoo:

Cov txheej oxide uas tsim los ntawm ntuj tsim rau ntawm qhov chaw ntawm titanium alloy pab txhawb rau qhov tshwm sim ntawm kev sib koom ua ke ntawm cov pob txha thiab txhim kho qhov kev sib txuas ntawm cov hniav cog thiab pob txha.

Taw qhia ob qho khoom siv titanium alloy uas tsim nyog tshaj plaws:

Kev ua tau zoo ntawm TC4:

TC4 alloy muaj 6% thiab 4% vanadium. Nws yog α + β hom alloy uas siv dav tshaj plaws nrog cov zis loj tshaj plaws. Nws muaj lub zog nruab nrab thiab plasticity tsim nyog. Nws yog siv dav hauv aerospace, aviation, tib neeg cog (pob txha cuav, pob qij txha ntawm tib neeg lub duav thiab lwm yam khoom siv biomaterials, 80% ntawm cov uas tam sim no siv cov alloy no), thiab lwm yam. Nws cov khoom tseem ceeb yog cov tuav thiab ncuav mog qab zib.

Ti6AL7Nbkev ua tau zoo

Ti6AL7Nb alloy muaj 6% AL thiab 7% Nb. Nws yog cov khoom siv titanium alloy siab tshaj plaws uas tau tsim thiab siv rau kev cog hniav hauv Switzerland. Nws zam qhov tsis zoo ntawm lwm cov alloys cog hniav thiab ua lub luag haujlwm zoo dua ntawm titanium alloy hauv ergonomics. Nws yog cov khoom siv cog hniav cog hniav zoo tshaj plaws yav tom ntej. Nws yuav siv dav hauv kev cog hniav titanium, kev cog pob txha cog hniav, thiab lwm yam.

Hauv kev xaus, titanium ua cov khoom siv cog rau hauv pob txha muaj qhov zoo ntawm kev sib raug zoo ntawm biocompatibility, cov khoom siv kho tshuab, kev tiv thaiv corrosion, lub teeb yuag, tsis muaj magnetic thiab kev sib koom ua ke zoo ntawm pob txha, uas ua rau titanium yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv cog rau hauv pob txha.
