Kev siv thiab kev tsim kho tshiab ntawm titanium alloys hauv orthopedics

Titanium alloys, vim tias lawv lub cev thiab tshuaj lom neeg tshwj xeeb, ua lub luag haujlwm tseem ceeb hauv kev kho mob, tshwj xeeb hauv kev phais orthopedic. Lub elastic modulus ntawm ntshiab titanium yog nyob ze rau lub ntuj pob txha ntawm tib neeg lub cev, uas yog zoo los txo cov kev nyuaj siab shielding nyhuv thiab txhawb cov pob txha kho. Yog li ntawd, nws yog dav siv nyob rau hauv tib neeg orthopedic kev phais xws li lub luj tshib pob qij txha thiab pob qij txha.

1. The history and current situation of the application of titanium in orthopedics. Since 1972, my country has begun to use domestic titanium and titanium alloy artificial bones and joints for clinical treatment. Beijing Nonferrous Metals Research Institute is one of the earliest units in China to research titanium artificial joints. In 1973, it produced industrial pure titanium artificial femur and hip joints for clinical use. Txog tam sim no, txawm hais tias tus nqi ntawm cov titanium siv hauv kuv lub teb chaws txoj kev lag luam tsis tshua muaj zog, nws tau loj hlob sai, tshaj 30%, qhia lub peev xwm loj dua.

Titanium hlau tau zoo heev hauv kev pab kho cov kab mob orthopedic. Piv txwv li, nyob rau hauv kev kho ntawm Patella pob zeb loj yog, tus patella lub pob zeb yog qhov yooj yim rau kev ua haujlwm, txuag lub sijhawm thiab yog ib qho yooj yim los txhawb thiab thov. Tsis tas li ntawd, Titanium cov khoom xws li corrugated crimged suture suture cov phiaj xwm thiab cov phiaj xwm ntau pob kuj tseem siv nyob rau hauv kev kho mob pob txha thiab tau ua tiav cov teebmeem zoo.

2. Titanium alloy qib thiab daim ntawv thov Ti-6Al-4V thiab Ti-6Al-4VELI alloys yog cov laus titanium alloys thiab tau siv dav los ua cov khoom cog. Txawm li cas los xij, vim tias nws muaj cov tshuaj lom vanadium, uas yuav ua rau muaj kev phom sij rau tib neeg lub cev nyob rau lub sijhawm ntev, nws daim ntawv thov tau maj mam poob. Txhawm rau daws qhov teeb meem no, ntau qhov kev kho mob tsis muaj vanadium titanium alloys tau tsim thoob ntiaj teb, xws li Switzerland's Ti-6Al-7Nb alloy, kuv lub teb chaws cov tshuaj tsis muaj vanadium titanium alloy, lub teb chaws Yelemees Ti{ {9}}Al-2.5Fe alloy, Is Nrias teb Ti-5Al{13}}.5B alloy thiab Ti-15Mo-5Zr-3Al alloy, thiab lwm yam. Cov alloys tshiab no tsis tsuas yog ua kom muaj kev nyab xeeb ntawm cov khoom siv roj ntsha, tab sis kuj tseem txhim kho cov khoom siv kho tshuab kom tau raws li cov kev xav tau ntawm kev phais orthopedic.

3. Kev siv tshiab ntawm 3D luam ntawv thiab titanium hlau Nrog txoj kev loj hlob sai ntawm 3D luam ntawv thev naus laus zis, kev kho mob ntxiv kev tsim khoom ntawm titanium ntshiab tau pom tias muaj peev xwm loj hauv pob txha taub hau, kev kho hniav tsis zoo, thiab hloov lub duav. Kev tshawb fawb tau pom tias qhov tawv tawv ntawm 3D luam tawm ntshiab titanium mesh zoo dua li lwm cov diaphragms, uas muaj txiaj ntsig zoo rau kev tsim cov pob txha grafting cov ntaub ntawv. Tsis tas li ntawd, piv nrog kev lag luam titanium mesh, customized titanium mesh muaj qhov zoo ntawm lub sijhawm ua haujlwm luv dua thiab qis dua kev pheej hmoo ntawm kev kis mob tom qab. Txawm hais tias titanium hlau los yog titanium alloys tseem muaj qee yam kev txwv kev siv tshuab thiab lom neeg ua haujlwm raws li cov pob txha hloov cov ntaub ntawv hauv kev siv tshuaj kho mob, cov teeb meem no yuav tsum tau daws nrog kev txhim kho cov khoom siv tshiab xws li nanotechnology. Piv txwv li, biocompatibility thiab txhua yam khoom ntawm titanium alloys tuaj yeem txhim kho los ntawm nanomaterial txheej.

Hauv cov ntsiab lus, titanium alloys muaj kev cia siab thov cov kev cia siab hauv orthopedic tshuaj. Nrog kev nce qib nruam thiab kev hloov tshiab ntawm kev tshawb fawb thiab thev naus laus zis, nqa cov kev phais ntau dua thiab lub neej zoo rau cov neeg mob. Nyob rau tib lub sijhawm, lub titanium kev lag luam yuav tsum tau txeeb txoj hauv kev no los txhawb nws txoj kev loj hlob thiab ua rau muaj kev pab ntau rau tib neeg.
