Cov Lus Nug Ntawm Cov Khoom Siv Kho Mob Hlau

Raws li kev faib tawm ntawm cov ntaub ntawv biomedical, cov lus pom yav dhau los muaj cov khoom siv polymer li qub thiab cov ntaub ntawv bioceramic. Kab lus no yuav hais txog hom peb ntawm biomedical cov ntaub ntawv - cov ntaub ntawv kho mob hlau. Cov khoom siv kho mob hlau ua lub luag haujlwm tseem ceeb tshaj plaws hauv kev ua tshuaj niaj hnub no. Nrog lawv cov kws kho mob tshwj xeeb thiab cov neeg kho mob biocompatibility, lawv tau siv dav hauv ntau thaj teb xws li orthopedics, plawv, kho hniav thiab phais. Kab lus no yuav tham txog cov lus txhais, kev faib tawm, kev thov cov ntaub ntawv thiab kev siv ua haujlwm tom ntej no, thiab piav qhia lawv cov lus hauv tsev kho mob. 01 Khoom Kho Mob Hlau Hlau
Cov khoom siv kho mob hlau xa mus rau cov hlau thiab lawv cov almoial tshwj xeeb siv nyob hauv chav kho mob. Lawv feem ntau yog siv los tsim cov khoom siv kho mob thiab cov kev cog hniav ua ke tau sib chwv, thiab lwm yam, kev siv hluav taws xob suav, thiab lwm yam, kev ua haujlwm rau lub plawv, xeb tawm tsam thiab ruaj khov. Cov cuab yeej ua lwm yam yog qhov tseem ceeb ntawm cov khoom siv hlau hlau. Lawv yuav tsum muaj lub zog txaus thiab kev tawv tawv kom withstand ntau lub cev nyuab siab sab hauv thiab sab nraud tib neeg lub cev. Biocompatibility yog qhov tseem ceeb hauv kev siv cov ntaub ntawv hlau muaj kev nyab xeeb hauv tib neeg lub cev. Cov ntaub ntawv nrog rau biocompatibility zoo yuav tsis ua rau pom tseeb tsis muaj zog tiv thaiv kab tshoob, kev siv hluav taws xob Corrosion tsis kam yog qhov taw qhia tseem ceeb ntawm cov khoom siv hlau hlau vim tias thaj chaw sab hauv ntawm tib neeg lub cev yog ua rau muaj kev nyuaj thiab ua kom haum. Lub cev dej hauv tib neeg lub cev muaj ntau ions thiab lwg, thiab cov tshuaj no yuav corals. Yog li, cov ntaub ntawv hlau kho mob yuav tsum nyob ruaj khov nyob rau hauv xws li ib puag ncig thiab tsis yauv txhim kho corrosion.
02 Kev faib khoom ntawm cov khoom siv hlau
Cov ntaub ntawv hlau siv tau tsuas yog muab faib ua cov hlau stainless, titanium thiab nws cov alloys thiab maglocesium alloys raws li lawv cov tshuaj lom neeg muaj pes tsawg leeg.
1 stainless hlau
Stainless hlau yog ib qho ntawm cov ntaub ntawv hlau ntxov tshaj plaws hauv kev kho mob thiab muaj cov khoom siv zoo thiab corrosion tsis kam. 316L stainless hlau tshwj xeeb yog feem ntau hauv kev siv tshuaj kho mob vim nws cov ntsiab lus muaj roj carbon ntau thiab ntxiv molybdenum. Nws yog ib feem siv los tsim kev phais cov cuab yeej, pob txha plates thiab screws. Txawm hais tias Stainless hlau yog tus nqi kuj pheej yig thiab muaj cov txheej txheem zoo, nws cov corrosion tsis kam thiab biocompatibility tseem yuav tsum tau txhim kho cov ntawv thov kev ua kom pom kev zoo.
2 titanium thiab nws cov alloys
Titanium alloy yog ib qho ntawm feem ntau dav siv cov ntaub ntawv siv hlau hlau. Titanium muaj tsawg ntom ntom, muaj lub zog siab, zoo sib xws heev rau cov pob txha pob txha mos, yog li nws tau siv dav hauv orthopedic kev cog lus xws li hip thiab lub hauv caug hloov. Ti {-6 al -4 v Yog cov khoom siv titanium ntau tshaj plaws vim nws cov khoom siv kho tshuab zoo nkauj thiab kev ua haujlwm biocompatibility. Txawm li cas los xij, ib qho tsis zoo ntawm titanium alloys yog nws tus nqi siab thiab nyuaj ua kev ua.
3 Cobalt-Chromium alloys
Cobalt-chromium alloys muaj lub zog siab heev thiab tsim tau kom haum rau cov khoom siv kho mob uas xav tau cov khoom siv thiab kho hniav. Lub siab tawv thiab corrosion tsis kam ntawm cobalt-chromium alloys muab nws cov kev tiv thaiv loj heev, tab sis yog, qhov kev cuam tshuam ntawm cov phom sij ntawm "uas yuav cuam tshuam rau kev loj hlob ntawm cov pob txha.
4 Cov Hlau Muaj Nqis
Xws li Kub, Nyiaj Platinum, thiab lwm yam, vim lawv cov ntawv thov kho mob zoo, xws li cov khoom noj khoom haus tshwj xeeb thiab kev kho dua hniav. Txawm li cas los xij, vim lawv cov nqi siab thiab cov khoom siv tsawg dua, kev siv cov hlau sib luag yog raug rau qee qhov kev txwv.
5 magnesium alloy
Magnesium alloy yog hom tshiab ntawm biodegradable hlau khoom. Nws yog kev tshawb fawb hotspot vim nws cov khoom siv neeg kho kom zoo thiab biocompatibility. Qhov ceev thiab loj hlob moldulus ntawm cov hlau nplaum zoo ib yam li cov pob txha tib neeg. Nws tuaj yeem muaj kev tawm tsam ib qho hauv lub cev thiab thaum kawg nqus tau los ntawm lub cev, zam kev yuav tsum tau phais ntxiv kom tshem nws. Txawm li cas los xij, cov kev tawm suab ceev thiab hydrogen tso tawm ntawm cov hlau nplaum magys tseem yuav tsum tau daws ntxiv.
03 daim ntawv thov ntawm cov ntaub ntawv kho mob hlau
Cov ntaub ntawv hlau siv dav hauv ntau yam kev kho mob vim lawv ua tau zoo, suav nrog orthopedics, kho hniav, kev kho hniav thiab lwm daim teb.
1 orthopedic daim ntawv thov
Nyob rau hauv lub teb ntawm orthopedics, cov ntaub ntawv hlau siv yog siv los tsim cov khoom siv pob txha thiab cov pob txha caj pas thiab cov pob txha caj pas thiab cov pob txha caj pas los ntawm lawv cov khoom siv roj caryo zoo nkauj thiab cov khoom siv neeg kho tshuab. Cobalt-chromium alloys feem ntau siv nyob rau saum npoo ntawm kev sib koom tes dag vim lawv cov coj tsis kam thiab siab tawv. Nyob rau hauv xyoo tsis ntev los no, kev tshawb fawb kev kawm ntawm cov hlauesium alloys tau pom nws lub peev xwm los ua cov pob txha pob txha pob txha, uas tuaj yeem zam rau qhov kev phais mob thib ob.
2 daim ntawv thov cov hlab ntshav
Nyob rau hauv cov hlab plawv, stainless hlau thiab cobalt-chromium alloys feem ntau siv los tsim cov implow xws li tccular stents thiab lub plawv li qub. Vascular stents yuav tsum muaj lub zog siab, corrosion tsis kam thiab zoo biocompatibility kom tiv thaiv kev so lossis thaiv cov hlab ntshav. Stainless hlau stents tau ib zaug dav vim yog lawv cov nqi qis thiab yooj yim tam sim no tau tig mus rau cobalt-chromium alloys lossis tshuaj siv cov stents.
3 Kev Kho Hniav
Nyob rau hauv daim teb hniav, titanium thiab nws cov alloys tau dav hauv kev cog hniav vim tias lawv muaj cov pob txha ua kom muaj zog hauv cov pob txha alveolar. Tsis tas li ntawd, cobalt-chromium alloys tseem dav siv tau cov ntaub ntawv rov kho hniav rov qab xws li cov kaus mom thiab txuas ntxiv vim yog lawv lub corrosion tsis kam thiab hnav tsis kam.
4 Lwm cov ntawv thov phais
Medical metal materials are also widely used in other surgical fields, such as skull repair plates in neurosurgery, prostheses in plastic surgery, and the manufacture of surgical instruments. Stainless hlau yog tseem cov khoom tseem ceeb rau kev tsim cov kev tsim cov twj paj phais vim nws cov khoom siv zoo thiab corrosion tsis kam.
04 yav tom ntej zeem muag thiab cov ntsiab lus
Cov ntaub ntawv siv hlau hlau muaj txoj haujlwm tsis txaus ntseeg hauv cov tshuaj niaj hnub no. Nrog rau kev nce qib nruam ntawm kev tshawb fawb thiab thev naus laus zis thiab cov khoom siv hlau siv txuas ntxiv mus ntsib cov kev cov nyom ntawm cov kev xav tau kev pab ntau yam ntawm kev xav tau kev pab ntau yam ntawm kev xav tau kev kho mob ntau yam. Kev tshawb fawb yav tom ntej yuav tsom rau kev txhim kho biocompatibility, ua kom zoo dua cov ntaub ntawv tshiab, thiab kev ua tiav cov neeg mob tshiab uas muaj kev nyab xeeb dua. Hauv cov ntsiab lus, kev txhim kho cov khoom siv hlau hlau tsis yog nyob ntawm cov ntaub ntawv kev tshawb fawb thiab engineering, tab sis kuj tseem yuav tsum tau hla cov tshuaj thiab lwm yam kev qhuab qhia los tsim cov kev tshawb fawb dav dav. Nyob rau hauv lub neej yav tom ntej, nrog rov tshwm sim ntawm ntau cov ntaub ntawv tshiab thiab thev naus laus zis, cov khoom siv hlau ua haujlwm yuav muaj kev pab ntau dua rau kev kho mob kom zoo thiab kev noj qab haus huv.
