Taw qhia rau plab hnyuv Stents

Lub plab hnyuv stent yog cov cuab yeej kho mob, feem ntau yog cov qauv tubular ua los ntawm cov hlau lossis yas, siv los daws cov kab mob plab hnyuv uas tshwm sim los ntawm txoj hnyuv stenosis lossis occlusion. Cov plab hnyuv stents tuaj yeem cog rau hauv qhov chaw endoscopy lossis los ntawm qhov me me hauv daim tawv nqaij, thiab kev cog cov stents tuaj yeem nthuav dav qhov nqaim ntawm txoj hnyuv kom rov ua kom lub plab hnyuv thiab ua haujlwm. Kev cog qoob loo ntawm txoj hnyuv stent tuaj yeem siv los kho ntau yam kab mob hauv plab, xws li mob plab hnyuv, kab mob plab hnyuv, mob qog noj ntshav, thiab lwm yam. Txoj kev kho mob no muaj qhov zoo ntawm kev tsis sib haum xeeb, ceev ceev, thiab ua haujlwm zoo, uas tuaj yeem txhim kho qhov zoo ntawm cov hnyuv. lub neej ntawm cov neeg mob thiab alleviate lawv qhov mob thiab tsis xis nyob cov tsos mob.

Lub plab hnyuv stent yog ib yam tshiab ntawm cov cuab yeej kho mob, thiab nws txoj kev loj hlob tuaj yeem taug qab mus rau thaum xaus xyoo 1970s thiab thaum ntxov 1980s. Thawj lub plab hnyuv stent yog ua los ntawm cov yas thiab feem ntau yog siv los kho cov plab hnyuv sab sauv los ntawm cov kab mob malignant xws li mob qog noj ntshav thiab mob ntsws cancer. Nrog rau kev txhim kho cov cuab yeej siv kho mob, hlau stents tau siv dav hauv kev kho mob plab hnyuv.

Xyoo 1991, Lub Chaw Tswj Xyuas Khoom Noj thiab Tshuaj (FDA) ntawm Tebchaws Meskas tau pom zoo thawj cov hlau stent rau kev kho mob ntawm biliary nruj thiab occlusion. Txij thaum ntawd los, daim ntawv thov ntawm cov hlau stents tau maj mam nthuav dav los kho ntau yam kab mob plab hnyuv thiab occlusion, xws li mob qog noj ntshav, mob plab, mob plab duodenal, mob qog noj ntshav, mob qog noj ntshav, mob qog noj ntshav thiab mob qog noj ntshav.

Nyob rau hauv xyoo tas los no, nrog kev txhim kho txuas ntxiv ntawm kev kho mob thev naus laus zis, kev tsim thiab cov khoom siv ntawm cov hnyuv stents kuj tau txhim kho ntxiv. Kev tsim cov hnyuv niaj hnub stents yog ntau dua nyob rau hauv txoj kab nrog biomechanical cov hauv paus ntsiab lus, uas tuaj yeem hloov kho kom zoo dua rau cov yam ntxwv ntawm cov hnyuv thiab daws cov teeb meem nyuaj. Nyob rau tib lub sijhawm, kev xaiv ntawm cov ntaub ntawv kuj muaj ntau haiv neeg, xws li stainless hlau, cobalt chromium alloy, ntshiab titanium, thiab npib tsib xee titanium alloy. Cov ntaub ntawv tshiab no tsis yog tsuas yog muaj cov khoom siv zoo dua qub xwb, tab sis kuj tseem muaj ntau dua corrosion-resistant thiab biocompatible, uas tuaj yeem txo qhov tshwm sim ntawm qhov tshwm sim tsis zoo thiab teeb meem tom qab stent implantation.

Raws li txoj kev kho mob sai thiab zoo, stent tau siv dav thiab ua lub luag haujlwm tseem ceeb hauv kev kho mob plab hnyuv stenosis thiab occlusion. Nrog rau kev txhim kho tas mus li thiab kev txhim kho thev naus laus zis, nws ntseeg tau tias cov hnyuv stents yuav muaj ntau qhov kev thov rau yav tom ntej.
