Khoom Taw qhia
Taw qhia rau nickel titanium alloy raj
Nitinol raj yog ib puag ncig khoom tsim los ntawm nickel titanium alloy. Nitinol tube yog cov khoom siv hlau nrog lub cim xeeb zoo thiab hloov tau yooj yim. Nws muaj qhov zoo nkauj du, siab nto tiav thiab xim tsaus. Thaum ua cov kav dej nickel-titanium sib xyaw, cov txheej txheem txias txias lossis cov txheej txheem kub kub feem ntau yog siv, uas tsis tsuas yog ua kom cov khoom zoo tag nrho ntawm cov kav dej nickel-titanium alloy, tab sis kuj tuaj yeem tswj cov duab nyuaj. Nickel-titanium raj muaj superelasticity thiab zoo lub cim xeeb zog, tuaj yeem rov tsim kho lawv cov duab tshwj xeeb hauv lub sijhawm luv luv, thiab muaj peev xwm deformation muaj zog los hloov mus rau qhov sib txawv ntawm cov kev xav tau.

daim ntawv thov:
Nitinol tubes nthuav tawm lub cim xeeb thiab superelastic zog thaum ua.
Biocompatible thiab non-toxic: ua kom nws zoo tagnrho rau kev siv ntau yam khoom siv kho mob, suav nrog hauv vascular stents, lub plawv bypasses, cov cuab yeej phais, endoscopes thiab guidewires. Lub cim xeeb zoo thiab cov khoom superelastic: Nws tuaj yeem rov qab mus rau nws cov duab qub tom qab deformation thiab tuaj yeem siv rau qee qhov kev phais me me. Qhov siab ntawm kev khoov thiab sib tw yuav tsis ua rau cov qauv kev ncaj ncees lossis ua rau cov ntaub so ntswg puas. Yog li ntawd, nws yog tshwj xeeb tshaj yog pab tau nyob rau hauv minimally invasive phais. Tsis tas li ntawd, lub raj yog cov corrosion-resistant thiab tuaj yeem yooj yim tuav cov txheej txheem kom tsis muaj menyuam. Hauv cardiology, nickel-titanium raj feem ntau yog siv rau hauv coronary stents los kho cov ntshav ntws mus rau cov hlab ntsha. Urologists siv nickel-titanium raj thaum lub sij hawm endoscopy kom tshem tawm cov zais zis thiab lub raum pob zeb. Neurologists kuj siv lub raj los ua qhov tsawg kawg nkausinvasive phais kom tshem tawm cov qog hlwb.
Kuv ua tib zoo saib xyuas qhov ntim ntawm cov khoom thiab zam kev puas tsuaj thaum thauj cov khoom.
Ua ntej tshaj plaws, yuav tsum tsis txhob xoob hauv chav ntim khoom kom tsis txhob muaj kev sib tsoo thaum lub sijhawm thauj mus los thiab kev puas tsuaj los ntawm kev cuam tshuam sab nraud.
Qhov thib ob, nyob ntawm seb muaj pes tsawg, rau ib qho me me ntawm cov kav dej nickel, peb yuav muab cov yas tiv thaiv npog rau txhua cov yeeb nkab. Yog tias qhov ntau npaum li cas, peb yuav muab cov yas tiv thaiv zaj duab xis rau ntawm lub hom phiaj, thiab siv daim txhuam cev los cais cov kav dej ntawm cov thawv ntoo. Qhib kom tiv thaiv tau lub thawv ntoo khawb cov yeeb nkab thaum thauj. Li no nce kev nyab xeeb ntawm cov kav dej txias.
