Hypotube txhais

Mob taw tes

Cov kws tshaj lij tshiab rau cov khoom siv cuam tshuam feem ntau kho lub hypotube li "tsuas yog lub raj hlau xwb." Qhov kev xav ntawd ua rau muaj kev ua tsis tiav loj. Ib lub raj muaj zog tuaj yeem thawb zoo tab sis tsis tuaj yeem taug kev tortuous coronary lossis neurovascular anatomy. Ib tug polymer ncej yuav khoov tau yooj yim tab sis poob torque thiab buckles nyob rau hauv load. OEMs ces iterate rau lub hlis, hloov coatings thiab tuav, thaum tsis quav ntsej qhov teeb meem tiag tiag: lub ncej nws tus kheej yeej tsis engineered. Qhov tshwm sim yog kev taug qab tsis zoo, torque hysteresis, kink ntawm aortic arch, thiab ncua kev pom zoo cov khoom.

Txoj Cai

Lub hypotube yog ib tug precision nyias-walled hlau raj-feem ntau 304, 316L, 17-7PH, Nitinol, los yog L605-uas ua raws li tus neeg kho tshuab txha nraub qaum ntawm ib tug catheter los yog xa system. Nws lub hwj chim los ntawmxaiv cov khoom tshem tawm. Lub hauv paus raj nqa axial thawb thiab tig torque. Laser txiav tshem tawm hauv zos nruj thiab tsim kom yooj yim. Cov choj tsis raug txiav khaws cia txuas ntxiv. Nrog kerf zoo li 0.012 hli thiab txoj kab uas hla ntawm Ø0.20 hli mus rau 20 hli, lub raj tuaj yeem ua haujlwm tau: nruj proximally, saj zawg zog distally, torque - ruaj khov nyob rau hauv nruab nrab, kink - tiv taus ntawm qhov khoov.

Beam txoj kev xav piav qhia nws yooj yim: khoov cov nplais nrog phab ntsa geometry; torsional stiffness nyob ntawm cov khoom siv tsis raug txiav. Lub laser - txiav qauv yog li ntawd tsis kho kom zoo nkauj - nws yog mechanical coding.

Kev faib khoom siv

• Precision raj kos lub rooj zaum: tsim seamless kho mob-qib tubing
• Fiber laser raj cutters: dav stainless hlau thiab cobalt alloy txiav
• Femtosecond / UV lasers: nplua Nitinol thiab nyias -cov hlab ntsha nrog HAZ tsawg
• 5-axis CNC laser workstations: kauv, radial, brickwork, jigsaw qauv
• Electropolish / passivation kab: tshem tawm recast, txhim kho lubricity thiab corrosion kuj
• Torque- khoov- qaug zog rigs: validate soj ntsuam kev ua tau zoo, tsis yog qhov ntev

Cov lus qhia tswv yim

Pib nrog txoj kev kho mob. Coronary ua hauj lwm xav tau torque thiab thawb. Neuro ua hauj lwm xav tau atraumatic yooj. Peripheral ua hauj lwm xav tau kink kuj. Kev ua haujlwm tso zis xav tau kev tiv thaiv corrosion thiab du navigation. Xaiv 316L rau lub cev-kua kua, Nitinol rau superelastic navigation, 17-7PH rau siab-lub zog xa, 304 rau cov nqi-sensitive dav siv. Txhais OD, ID, phab ntsa, txiav qauv, hloov chaw, thiab nto tiav ua ntej txiav. Tsis txhob qhia "gauge nkaus xwb." Validate torque kis tau tus mob, thawb quab yuam, kink lub kaum sab xis ntawm 50% lumen poob, thiab cyclic dabtsi yog khoov qaug zog.

Kev paub tiag - ntiaj teb

Ib qho kev pab cuam lub zais pa siv cov khoom 304 ncej. Nws thawb tau zoo tab sis tsis tuaj yeem hla ib qho mob tortuous. Hloov mus rau qhov cuam tshuam kauv hypotube khaws cia lub zog thaum ntxiv qhov hloov pauv. Hla txoj kev vam meej txhim kho yam tsis tau hloov lub zais pa. Lwm qhov kev pab cuam neuro dhau -txiav lub ntsiab lus rau "floppiness"; lub ntsis folded nyob rau hauv laub. Qhov kho tsis yog cov khoom siv tshiab- nws yog cov qauv ntsuas nrog ntau cov hlau tsis sib xws thiab cov softer tab sis txhawb qhov chaw nyob deb.

Xaus

Lub hypotube tsis yog tubing. Nws yog ib tug mechanically programmed ncej. Leej twg tswj cov kev pab cuam txiav txiav tswj cov cuab yeej xav tau ntawm tus kws kho mob txhais tes.

Outlook

Yav tom ntej hypotubes yuav yog generative-tsim: anatomy hauv, qauv tawm. AI yuav tawm tswv yim muab kauv / radial / hybrid zones, simulation yuav kwv yees lub zog hysteresis, thiab lub raj yuav dhau los ua tus neeg mob - cov khoom siv tshwj xeeb.
