Daim ntawv thov ntawm titanium hauv plawv Stents
Lub plawv stents, tseem hu ua coronary stents, ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov hlab ntsha tsis tu ncua, daws teeb meem stenosis, thiab ua kom cov ntshav ntws zoo. Cov cuab yeej kho mob no feem ntau yog siv los kho cov mob plawv mob xws li mob myocardial infarction, thiab yog cov cuab yeej tseem ceeb rau kev cawm neeg txoj sia. Nrog kev txhim kho txuas ntxiv ntawm kev kho mob thev naus laus zis, daim ntawv thov ntawm titanium hauv plawv stents tau maj mam dhau los ua qhov tseem ceeb ntawm kev kho mob. Yog li, dab tsi ua rau titanium nrov hauv daim ntawv thov ntawm lub plawv stents?
Lub plawv stents yog cov cuab yeej tseem ceeb los pab tshem tawm cov hlab ntsha los yog nqaim, thiab titanium tau dhau los ua cov khoom siv zoo tshaj plaws rau kev tsim lub plawv stents vim nws qhov tshwj xeeb biocompatibility, lub zog thiab corrosion kuj. Piv nrog rau cov tsoos stainless hlau los yog npib tsib xee-titanium alloys, titanium ua tau zoo dua hauv kev txo cov kev mob tshwm sim ntau dhau thiab kev tsis lees paub, yog li txo qhov kev pheej hmoo ntawm cov teeb meem tom qab phais hauv cov neeg mob.
Titanium kuj yog lub teeb nyob rau hauv qhov hnyav thiab hnav-resistant, uas tsis tsuas yog ua rau nws yooj yim rau cog lub plawv stents, tab sis kuj prolongs lub neej kev pab cuam ntawm lub stent. Vim qhov ntom ntom ntom thiab zoo corrosion tsis kam ntawm Titanium lub plawv STRE, nws tuaj yeem nyob ruaj khov hauv lub cev tshwm sim ntawm kev rov ua haujlwm tom qab. Tsis tas li ntawd, titanium alloy lub plawv stents kuj muaj qee qhov zoo hauv kev xa tawm, tso cai rau cov kws kho mob saib xyuas cov nyhuv implantation ntawm stent kom meej meej.
Kev tsim cov txheej txheem ntawm titanium alloy lub plawv stents yog qhov muag heev. Raws li kev kho mob sib txawv, lub raj lub cev ntawm stent yuav raug "carved". Qhov stent no yog tsim los txhawb cov hlab ntsha tsis ua rau lub siab ntau dhau ntawm cov ntaub so ntswg.
Raws li kev txheeb cais, ntau tshaj 10 lab titanium alloy lub plawv stent implantations tau ua tiav thoob ntiaj teb. Daim duab no tsis tsuas yog qhia txog kev siv dav ntawm titanium alloy lub plawv stents, tab sis kuj qhia txog nws txoj haujlwm tseem ceeb hauv kev kho mob.
Thaum lub sij hawm percutaneous coronary zais pa angioplasty, tus kws kho mob yuav muab ib tug pre-folded titanium alloy lub plawv stent rau lub zais pa. Thaum lub zais pa nthuav dav, lub stent tseem yuav qhib thiab kho hauv cov hlab ntsha nqaim. Qhov no yog lub hauv paus ntsiab lus ntawm intracoronary stent implantation.
Tam sim no, kwv yees li 80% ntawm cov kev cuam tshuam ntawm cov hlab ntsha hauv kev kho mob yuav ua rau lub plawv stents. Cov stents no tuaj yeem tsis tsuas yog txo cov neeg mob cov tsos mob, tab sis kuj tseem txhim kho lawv lub neej zoo. Nws yog precisely vim hais tias ntawm cov zoo heev daim ntawv thov ntawm titanium hlau nyob rau hauv lub plawv stents uas suav tsis tau lub neej tau txais kev cawmdim.
Nrog rau kev tsim kho tshiab tas mus li thiab kev txhim kho ntawm kev kho mob thev naus laus zis, peb muaj laj thawj ntseeg tias titanium alloy lub plawv stents yuav txuas ntxiv mus ua si lawv cov txiaj ntsig zoo yav tom ntej thiab txhim kho nyob rau hauv kev ua kom zoo dua qub thiab tus kheej. Nyob rau tib lub sijhawm, nrog kev tshwm sim tas li ntawm cov ntaub ntawv tshiab thiab cov thev naus laus zis tshiab, kev ua haujlwm thiab kev nyab xeeb ntawm titanium alloy lub plawv stents yuav raug txhim kho ntxiv.
