Daim Ntawv Thov Titanium hauv Tshuaj

1, Raws li cov khoom siv tawm tshiab, titanium tau siv rau hauv kev lag luam tshuaj, cov cuab yeej phais, tib neeg cog thiab lwm yam kev lag luam tau ntau xyoo, thiab tau ua tiav zoo.

2, pob txha thiab pob qij txha raug mob los ntawm kev raug mob thiab qog, siv titanium thiab titanium alloy tuaj yeem ua rau cov khoom sib txuas, phaj thiab ntsia hlau tau siv dav hauv kev kho mob. Nws kuj tseem siv tau rau hauv lub duav (xws li lub taub hau femoral), lub hauv caug pob qij txha, lub luj tshib sib koom ua ke, metacalangeal sib koom ua ke, interphalangeal sib koom, qis M-pob txha, dag lub cev pob txha (spinal orthosis), lub plawv pacemaker plhaub, dag lub plawv (lub plawv valve), dag. kev cog hniav, thiab titanium mesh hauv cranium reconstruction thiab lwm yam.

3, Cov kev cai rau cov khoom cog tuaj yeem muab faib ua peb yam: biocompatibility ntawm cov ntaub ntawv nrog tib neeg lub cev, corrosion kuj ntawm cov ntaub ntawv nyob rau hauv tib neeg ib puag ncig thiab txhua yam khoom ntawm cov khoom. Raws li cov khoom siv cog rau lub sijhawm ntev, muaj xya qhov tshwj xeeb raws li hauv qab no:

(1) corrosion kuj;

(2) biocompatibility;

(3) Cov khoom zoo heev thiab kev qaug zog;

(4) toughness;

(5) Tsawg elastic modulus;

(6) Zoo hnav tsis kam hauv kev sib xyaw ua ke;

(7) Txaus siab tus nqi;

4, Cov khoom siv phais phais feem ntau suav nrog: hlau, polymer, ceramic, thiab lwm yam, cov ntaub ntawv hlau muaj xws li stainless hlau thiab titanium puag alloy.

Stainless hlau yog pheej yig thiab yooj yim rau txheej txheem, tab sis corrosion kuj thiab biocompatibility tsis zoo li titanium alloy; titanium thiab titanium alloys nyiam ntau thiab ntau xim vim lawv lub zog tshwj xeeb, zoo biocompatibility thiab zoo kuj. Qhov tsis zoo ntawm titanium alloy yog cov hnav tsis zoo, tsis yooj yim rau cam khwb cia, thiab kev ua haujlwm tsis zoo.
