Daim ntawv thov ntawm nickel titanium nco alloy hauv nws tus kheej nthuav kev kho mob stents

Nickel titanium nco alloy, nrog nws cov duab zoo heev nco cov txiaj ntsig thiab super elasticity, tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev tsim tus kheej nthuav dav kev kho mob stents. Cov hlau no tuaj yeem tsis tsuas yog rov qab nws cov duab qub nyob rau hauv cov xwm txheej tshwj xeeb, tab sis kuj tsim kom muaj zog nthuav dav, muab cov tshuaj tshiab rau kev kho ntau yam kab mob nqaim.

1. Cov yam ntxwv ntawm Nickel Titanium Memory Alloy

Nickel titanium nco alloy yog cov khoom siv hlau uas muaj cov cim cim cim xeeb thiab superelasticity. Nws tuaj yeem rov qab mus rau nws cov duab qub nyob rau hauv cov xwm txheej tshwj xeeb (xws li kev hloov pauv kub) thiab tsim kom muaj zog nthuav dav. Cov yam ntxwv no ua rau npib tsib xee titanium nco alloy zoo heev rau kev tsim tus kheej nthuav dav kev kho mob stents.

2. Daim ntawv thov ntawm tus kheej expanding kho mob stent

1) Esophageal stent

Nickel titanium nco alloy esophageal stents yog dav siv los kho esophageal stenosis los ntawm malignant lesions. Kev cog cov stents tuaj yeem txo cov tsos mob sai sai xws li nqos nyuaj rau cov neeg mob thiab txhim kho lawv lub neej zoo. Meanwhile, coated stents kuj siv tau rau kev kho mob ntawm malignant stenosis nyob rau hauv cov kab noj hniav, txo kev loj hlob thiab kis ntawm cov qog hlwb.

2) Biliary stent

Nyob rau hauv daim teb ntawm biliary ib ntsuj av, nickel titanium nco alloy stents kuj yog siv los kho cov kab mob xws li extrahepatic ntau cov kua tsib duct obstruction los yog stenosis, nrog rau biliary anastomotic stenosis. Kev cog qoob loo ntawm stents tuaj yeem kho cov patency ntawm cov kab mob biliary, txo qhov kev pheej hmoo ntawm cov kua tsib stasis thiab kab mob.

3) Cardiovascular stent

Cov nickel titanium nco alloy cardiovascular stent tuaj yeem raug compressed rau ib txoj kab uas hla me me thaum lub sij hawm tso thiab rov qab los rau nws cov duab qub thaum tso tawm, kom ntseeg tau tias kev txhawb nqa ntawm cov hlab ntsha. Hom stent no tau dav siv los nthuav dav thiab txhawb nqa cov hlab ntsha nqaim lossis occluded, txhim kho cov ntshav khiav, thiab txo cov kev pheej hmoo ntawm cov kab mob plawv.

4) Lwm yam kev siv

Ntxiv nrog rau cov ntawv thov saum toj no, cov nickel titanium nco alloy stents kuj tseem siv los kho cov kab mob peripheral arterial (xws li ceg hlab ntsha stenosis lossis occlusion), kho aneurysm, ureteral stenosis lossis obstruction, urethral stenosis lossis obstruction, thiab lwm yam kab mob. Tsis tas li ntawd, nyob rau hauv lub tshav pob ntawm orthodontics, npib tsib xee titanium nco alloys kuj siv los tsim orthodontic xov hlau thiab lwm yam khoom siv orthodontic.

3. Qhov zoo ntawm nickel titanium nco alloy stent

1) Zoo biocompatibility: Nickel titanium nco alloy muaj biocompatibility zoo thiab tuaj yeem khaws cia rau hauv lub cev ntev yam tsis ua rau muaj kev phiv tshuaj.

2) Cov nyhuv nco zoo: Lub stent tuaj yeem rov qab mus rau nws cov duab qub nyob rau hauv cov xwm txheej tshwj xeeb thiab tsim kom muaj zog nthuav dav, ua kom ruaj khov thiab ua tau zoo ntawm stent.

3) Yooj yim rau kev khiav lag luam: Cov txheej txheem implantation ntawm stent yog qhov yooj yim, tsis tas yuav tsum muaj cov txheej txheem phais nyuaj, txo qhov kev pheej hmoo ntawm kev phais thiab mob rau cov neeg mob.

4) Recyclability: Qee cov nickel titanium nco alloy stents yog tsim los ua dua tshiab, ua kom yooj yim los hloov lossis tshem tawm thaum tsim nyog, txhim kho qhov yooj thiab kev nyab xeeb ntawm kev kho mob.

Daim ntawv thov ntawm npib tsib xee titanium nco alloy hauv nws tus kheej nthuav kev kho mob stents muaj qhov zoo thiab muaj kev cia siab dav. Nrog rau kev nce qib ntawm kev kho mob tsis tu ncua thiab kev tshawb fawb txuas ntxiv thiab txhim kho cov ntaub ntawv nickel titanium nco alloy, peb ntseeg tias yav tom ntej, cov khoom siv kho mob tshiab yuav tshwm sim rau cov nickel titanium nco alloys, muab kev xaiv zoo dua thiab lav rau cov neeg mob kev kho mob.
