Kub tswj nitinol caij nplooj ntoos hlavyog lub caij nplooj ntoos hlav ua los ntawm nitinol titanium alloy. Lub caij nplooj ntoos hlav zoo li no muaj cov yam ntxwv tswj qhov kub thiab txias, uas yog, thaum nws raug cuam tshuam los ntawm tshav kub, lub caij nplooj ntoos hlav yuav cia li ncab lossis luv kom ua tiav lub hom phiaj ntawm kev tswj qhov kub thiab txias.
Cov khoom no tseem hu ua Nitinol (Nickel Titanium). Nitinol yog cov hlau alloy nrog cov duab nco thiab superelasticity, muaj titanium thiab npib tsib xee. Lub caij nplooj ntoos hlav no feem ntau siv rau hauv cov khoom siv kho mob, cov cuab yeej siv dav hlau, cov khoom siv hluav taws xob, thiab lwm yam. Nws muaj cov khoom siv kho tshuab zoo heev thiab tuaj yeem tiv taus kev cuam tshuam ntawm kev kub siab, kub kub, thiab kev ntxhov siab ib puag ncig. Nyob rau tib lub sijhawm, nws tseem tuaj yeem tswj hwm thiab hloov kho kom tau raws li qhov xav tau ntawm ntau yam kev thov.
Lub cim xeeb zoo: Nitinol yog cov khoom siv tau yooj yim thiab pliable ntawm qhov kub thiab txias, tab sis cia li rov qab mus rau nws cov duab preset thaum rhuab mus rau qhov kub thiab txias. Qhov kev kho qhov tsis zoo no yog siv rau hauv ntau yam khoom siv kho mob, tsom iav qhov muag, braces, mechanical parts, thiab lwm yam.
Super elastic: Nitinol tuaj yeem rov qab mus rau nws cov duab qub thaum twisted thiab khoov. Cov cuab yeej no ua rau nws siv dav hauv kev kho mob, xws li stents, lub plawv li qub, vascular interventional stents, thiab lwm yam.

Kub tswj nitinol caij nplooj ntoos hlav yog lub caij nplooj ntoos hlav kub tswj raws li Shape Memory Alloy thev naus laus zis. Lub caij nplooj ntoos hlav yog ua los ntawm Nitinol (nickel-titanium alloy), cov khoom siv tshwj xeeb alloy nrog cov duab nco thiab superelasticity, uas tuaj yeem hloov pauv ntawm qhov kub sib txawv.
Thaum lub caij nplooj ntoos hlav nitinol yog rhuab, nws cia li hloov cov duab los ntawm cov duab nco nyhuv, muab lub siab xav binding quab yuam. Hloov pauv, thaum qhov kub thiab txias poob, lub caij nplooj ntoos hlav yuav txuas ntxiv deform txiav, tso tawm lub zog khi.
Yog li ntawd, nitinol caij nplooj ntoos hlav tuaj yeem kho nws elasticity raws li qhov kub thiab txias, paub txog kev tswj tsis siv neeg thiab kev tswj hwm. Nws yog dav siv hauv ntau daim ntawv thov, xws li hauv cov khoom siv kho mob, kev tswj tsis siv neeg, kev tsim kho, thiab kev lag luam tsheb.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm Nitinol caij nplooj ntoos hlav yog ua raws cov theem hloov pauv. Thaum qhov kub thiab txias nce mus rau theem kev hloov pauv kub, lub lattice qauv ntawm cov khoom siv Nitinol hloov, tso cai rau lub caij nplooj ntoos hlav los xav txog nws cov qauv qub.
Lub sijhawm hloov pauv kub ntawm Nitinol feem ntau yog nruab nrab ntawm 60 degree thiab 130 degree, nyob ntawm seb cov khoom muaj pes tsawg leeg thiab kev ua haujlwm.
4. Daim ntawv thov teb ntawm kev tswj qhov kub thiab txias nitinol caij nplooj ntoos hlav yog dav heev, cov hauv qab no yog qee qhov chaw
1) Cov cuab yeej kho mob: Nws tuaj yeem siv rau hauv kev tsim cov khoom stent, cov khoom siv catheter, thiab lwm yam khoom siv kho mob.
2) Auto qhov chaw: Nws tuaj yeem siv los tsim cov tshuab cua txias, cov twj tso kua mis, roj twj, thiab lwm yam.
3) Electronic field: Nws tuaj yeem siv los tsim hluav taws xob hluav taws xob, hluav taws xob hloov hluav taws xob, lub log hluav taws xob, thiab lwm yam khoom siv.
4) Kev tswj hwm kev lag luam: Nws tuaj yeem siv los tsim cov tshuab ntsuas kub rau cov cuab yeej tswj kev lag luam.
Hauv kev xaus, daim ntawv thov kev ntsuas kub ntawm nitinol caij nplooj ntoos hlav yog dav heev thiab tuaj yeem ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam nrog rau kev kho mob thiab hluav taws xob.
