Nitinol Hlau thiab Qws

Nitinol Hlau thiab Qws Description

Nitinol yog npib tsib xee-titanium alloy nrog tus qauv piv 40-50 feem pua ​​​​nickel, 50-60 feem pua ​​​​titanium hu ua lub cim xeeb alloy (SMA). Nitinol alloys nthuav tawm ob qho kev sib raug zoo thiab cov khoom tshwj xeeb: lub cim xeeb zoo thiab superelasticity (tseem hu ua pseudoelasticity). Lub cim xeeb zoo yog lub peev xwm ntawm nitinol kom dhau qhov deformation ntawm ib qhov kub thiab txias, nyob hauv nws cov duab deformed thaum lub zog sab nraud raug tshem tawm, tom qab ntawd rov qab nws cov qub, undeformed zoo li cua sov saum nws "kub hloov pauv". Superelasticity yog lub peev xwm rau cov hlau mus rau qhov loj deformations thiab tam sim ntawd rov qab mus rau nws cov duab undeformed thaum tshem tawm ntawm sab nraud load. Nitinol tuaj yeem deform 10-30 npaug ntau npaum li cov hlau zoo tib yam thiab rov qab mus rau nws cov duab qub. Txawm hais tias nitinol coj tus cwj pwm nrog lub cim xeeb zoo lossis superelasticity nyob ntawm seb nws puas siab dua qhov kev hloov pauv ntawm qhov tshwj xeeb alloy. Hauv qab qhov kev hloov pauv kub nws nthuav tawm cov duab cim xeeb, thiab saum toj no qhov kub thiab txias nws coj superelastically. Cov khoom txawv txawv no tau siv rau ntau hom kev siv hauv ntau qhov chaw sib txawv suav nrog cov cuab yeej kho mob thiab kev lag luam aerospace. Cov alloys sib txawv muaj npe raws li qhov hnyav feem pua ​​​​ntawm nickel; Piv txwv li, Nitinol 55 thiab Nitinol 60. Nws nthuav tawm cov duab nco zoo thiab superelasticity ntawm qhov kub sib txawv.

Nitinol hlau thiab nitinol pas nrig yog cov khoom tsim ntawm nickel-titanium alloy. SSC tsim cov nitinol hlau thiab pas nrig los ntawm ntau qib ntawm npib tsib xee-titanium alloy feem ntau siv hauv kev kho mob thiab rau lwm yam kev siv ntau yam. Cov khoom siv kho mob qib nitinol suav nrog npib tsib xee thiab titanium nyob rau hauv ze li qhov sib npaug atomic qhov hnyav feem pua; rau ASTM F2063, nickel cov ntsiab lus ntawm 54. Nitinol nrog cov sib txawv sib txawv thiab theem hloov pauv kub tuaj yeem siv rau lwm yam kev siv.

Nitinol yog tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau kev siv tshuaj kho mob vim nws muaj thermal nco. Ib qho tseem ceeb heev daim ntawv thov rau nitinol hlau yog qhov twg ib tug ntaus ntawv los yog cov qauv yuav tsum tau muab tso rau ntawm ib tug me me qhib thiab ces tso tawm mus qhib rau ib tug loj teeb loj. Ib qho qauv tuaj yeem raug compressed kom haum rau hauv lub me me txoj kab uas hla lub raj xa tuaj thiab muab tso rau hauv txoj hauj lwm thiab tso cai rau qhib rau ob peb zaug ntawm txoj kab uas hla ntawm lub raj xa khoom. Cov cuab yeej no tso cai rau cov stents yuav tsum tau ua ntawm ib txoj kab uas hla, txias, thiab ces compressed mus rau lub xa khoom. Thaum lub stent raug xa mus rau ntawm lub cev kub, lub stent sim rov ua nws qhov qub kev teeb tsa thiab txoj kab uas hla. Ib qho nitinol stent uas yog me ntsis oversized (kwv yees li 20 feem pua) hais txog lub nkoj siv lub zog sab nraud kom lub nkoj qhib thaum lub stent sim rov qab nws txoj kab uas hla.

Hauv kev siv neeg hlau, nitinol tuaj yeem siv los ua tus actuator qhov twg cov hluav taws xob tam sim no (lossis cua sov) tau siv rau cov hlau ncab, thiab cov hlau yuav cog lus thaum them nqi thiab so kom txaus thaum tus nqi raug tshem tawm. Tsis zoo li feem ntau cov hlau, nitinol cog lus ntev thaum rhuab tab sis yuav tuav tib lub ntim. Tsis tas li ntawd, nws cov thermal txav yog 100 npaug ntau dua li lwm cov hlau.

Rau kev xa tawm elastic, nitinol xaim tuaj yeem ua haujlwm nyob rau hauv qhov chaw hauv qhov chaw thiab tom qab ntawd muab tso rau hauv qhov dej kub da dej, ntawm qhov ntsuas kub thiab lub sijhawm, ua ntej yuav sai sai hauv dej txias. Thaum tshem tawm ntawm lub fixture, cov hlau tuav nws cov duab tsis hais lub kaum sab xis los yog siv ntawm deformation. Thaum tso tawm, cov hlau yuav rov qab mus rau nws qhov teeb tsa. Muaj ntau cov piv txwv ntawm daim ntawv thov no zoo li Homer Mammalok koob / hlau localizer. Cov hlau nkhaus yog pub los ntawm lub cannula ncaj thiab thaum tawm nws nkhaus mus rau hauv "J" zoo li nws tau teem tseg yav dhau los. Cov txheej txheem no tuaj yeem rov ua dua kaum ob zaug yam tsis muaj deforming.

Nitinol guidewires yog siv los coj cov catheters mus rau qhov nyuaj mus txog qhov chaw ntawm lub cev. Lawv zoo siab vim lawv yog cov kink resistant, tsis zoo li stainless hlau. Cov hlau yog elastic thiab nws tuaj yeem ua raws li txoj hauv kev tortuous hauv lub cev yam tsis muaj kev puas tsuaj. Nitinol yuav tig smoothly thiab impart torque. Nitinol xov hlau kuj tau siv los ua braided stents thiab lim.

SSC muab nitinol round hlau thiab pas nrig sib txawv Af (-20 degree rau 120 degree ). Peb tam sim no muaj peev xwm ua nitinol hlau thiab pas nrig tuav super-elasticity ntawm -10 degree . Peb kuj tsim cov hlau ca, square bar, rectangular bar ib qhov kev thov. multi-strand nitinol cable thiab lwm yam customized zoo rods & tuav kuj muaj.
