Nickel titanium nco alloy airway stent

Tracheal stent yog ib yam khoom siv kho mob uas feem ntau siv los kho cov kab mob ntsig txog kab mob xws li tracheal stenosis thiab tracheomalacia. Nws muaj cov nram qab no zoo thiab cov yam ntxwv:

Expanding txoj hlab pa:Tracheal stents tuaj yeem nthuav dav cov pa nqaim, rov ua pa ib txwm ua pa, thiab ua kom cov neeg mob ua pa ib txwm.

Muab kev txhawb nqa kev tsim kho:Lub tracheal bracket tuaj yeem muab cov qauv kev txhawb nqa rau cov pa roj yeeb nkab phab ntsa, tiv thaiv txoj hlab cua thiab kaw, thiab xyuas kom muaj cua patency.

Kho tau:Qee cov tracheal stents muaj cov qauv tsim kho uas tuaj yeem kho qhov nthuav dav raws li tus neeg mob tus mob, ua kom tau raws li tus neeg mob xav tau.

Thaum nws los txog rau cov khoom lag luam tracheal stent, cov hauv qab no yog qee cov khoom lag luam kom ntxaws ntxiv los pab cov neeg tuaj xyuas kom nkag siab ntau dua ntawm cov khoom:

Kev xaiv khoom siv:Tracheal stents feem ntau yog ua los ntawm cov khoom siv biodegradable zoo xws li polylactic acid lossis caprolactone, uas yog sib xws nrog tib neeg cov ntaub so ntswg thiab txo qhov kev pheej hmoo ntawm kev tsis lees paub.

Qauv qauv:Tracheal stent cov khoom feem ntau yog tubular nyob rau hauv cov duab, thiab tej zaum yuav muaj cov duab sib txawv thiab ntau thiab tsawg los xaiv los ntawm nyob ntawm seb qhov tshwj xeeb thiab kev xav tau.

Detachability: Qee cov tracheal stents yog tsim los rau hauv daim ntawv detachable kom hloov tau zoo dua rau cov kev hloov pauv ntawm tus mob thiab cov kev xav tau ntawm cov neeg mob. Qhov no tso cai rau cov kws kho mob kho qhov ntev thiab txoj kab uas hla ntawm stent raws li tus neeg mob tus mob.

Cov yam ntxwv ntawm elastic:Qee qhov tracheal stents muaj qee qhov kev elasticity, uas tuaj yeem hloov mus rau cov duab thiab txav ntawm lub trachea, yog li muab kev txhawb nqa zoo dua thiab hloov tau.

Dilation ntaus ntawv:Qee cov khoom lag luam tracheal stent tej zaum yuav nruab nrog cov cuab yeej dilation kom nthuav dav thaj chaw tracheal stenosis, rov ua kom lub ntsws zoo li qub, thiab txhim kho kev ua pa ntawm tus neeg mob.

Clinical feasibility:Tracheal stent cov khoom tau siv dav hauv kev kho mob thiab tau raug pov thawj tias yog txoj kev kho mob zoo thiab muaj txiaj ntsig.

Lub sij hawm ntev durability:Tracheal stents feem ntau muaj qhov ua haujlwm ntev dua thiab tuaj yeem tswj xyuas kev ua haujlwm zoo hauv tus neeg mob txoj hlab pa, txo cov sij hawm hloov thiab kev phais nyuaj.

Tus kheej tsim:Qee cov khoom siv tracheal stent tuaj yeem hloov kho raws li cov xwm txheej tshwj xeeb ntawm cov neeg mob kom ua tiav cov txiaj ntsig kev kho mob zoo dua.

Tracheal stent yog cov cuab yeej siv kho mob siv los kho tracheal stenosis los yog kev cuam tshuam, thiab nws cov ntawv thov feem ntau suav nrog cov hauv qab no:

Kev kho ntawm tracheal stenosis thiab obstruction:Tracheal stents tuaj yeem siv los kho ntau yam ua rau tracheal stenosis lossis kev cuam tshuam, xws li cov qog nqaij hlav, mob ntsws asthma, tracheal tuberculosis, kab mob tracheal stenosis, thiab lwm yam. Los ntawm kev txhawb nqa cov phab ntsa ntawm cov hlab ntsha, tracheal stents pab kho cov hlab ntsws patency, yog li txhim kho cov hlab ntsha. tus neeg mob txoj kev ua pa ua pa.

Tracheal stent implantation: Lub tracheal stent yog implanted rau hauv tus neeg mob lub trachea los ntawm endoscopy los yog phais. Thaum implantation, lub tracheal stent muab tso rau ntawm qhov chaw ntawm tracheal stenosis los yog kev cuam tshuam los pab txhawb thiab dilation.

Txo cov tsos mob thiab txhim kho lub neej zoo: Daim ntawv thov ntawm tracheal stents tuaj yeem txo cov tsos mob xws li ua tsis taus pa, hnoos, thiab ua tsis taus pa los ntawm tracheal stenosis lossis kev cuam tshuam, yog li txhim kho lub neej zoo ntawm cov neeg mob.
