Pain Points

Hauv kev cuam tshuam ntawm cov hlab plawv, kev xaiv cov khoom siv rau lub hypotube yog qhov tseem ceeb rau kev ua haujlwm ntawm cov cuab yeej thiab kev nyab xeeb ntawm tus neeg mob. Kev siv cov khoom siv tsis raug tuaj yeem ua rau corrosion, qaug zog tsis ua haujlwm, lossis cov khoom siv tsis zoo, ua rau muaj teeb meem ntawm cov txheej txheem. Stainless hlau qib 304 thiab 316L muaj ntau, tab sis lawv yuav tsis ib txwm muab qhov xav tau superelasticity lossis radiopacity. Nitinol muaj kink kuj zoo heev tab sis nyuaj rau cov txheej txheem. Tsis tas li ntawd, qhov sib piv rau cov khoom siv me me xav tau cov ntaub ntawv nrog lub zog siab dua - rau - qhov hnyav piv. Qhov mob taw tes yog nrhiav cov khoom zoo uas sib npaug ntawm kev tsim khoom, kev ua tau zoo, thiab biocompatibility rau txhua daim ntawv thov tshwj xeeb.

Txoj Cai

Lub hauv paus ntsiab lus ntawm kev xaiv cov khoom siv rau kev cai hypotubes suav nrog kev sib txuam ntawm cov khoom siv rau cov kev cai kho mob . 304 stainless hlau (1.4301) yog dav siv rau nws cov formability zoo thiab nruab nrab lub zog . 316L (1.4401) muaj superior corrosion kuj, ua rau nws haum rau ntev - lub sij hawm implants {{5}5}7} thiab treatment (AM) ntau dua {{5} 5} PH (7) S. rau cov khoom tshwj xeeb. Nitinol (Ni-Ti) nthuav tawm superelasticity thiab lub cim xeeb zoo, zoo tagnrho rau cov khoom siv uas yuav tsum taug txoj kev tortuous thiab rov qab los ntawm dabtsi yog khoov. Cov txheej txheem laser txiav yuav tsum tau ua kom haum rau txhua yam khoom; Piv txwv li, Nitinol yuav tsum tau txo cov cua sov kom tsis txhob hloov nws cov theem hloov pauv kub. Cov khoom xaiv, ua ke nrog lub laser-txiav qauv, txiav txim siab tag nrho cov kev ua tau zoo ntawm lub hypotube.

Kev faib khoom siv

Khoom siv - kev ua haujlwm tshwj xeeb yuav tsum muaj ntau yam laser tshuab. Fiber lasers yog zoo rau stainless hlau, thaum ultrafast lasers yog tsim nyog rau Nitinol los tiv thaiv thermal puas. Kev kho cua sov rauv yog siv rau cov ntaub ntawv zoo li 17-7PH kom ua tiav cov khoom siv kho tshuab uas xav tau. Cov cuab yeej kho deg, xws li cov tso tsheb hlau luam passivation rau stainless hlau thiab electropolishing rau tag nrho cov ntaub ntawv, xyuas kom biocompatibility. Cov khoom siv kuaj cov cav tov, suav nrog cov ntsuas tensile thiab cov neeg ntsuas qaug zog, xyuas kom meej tias cov hypotube tiav raws li cov lus qhia. Tag nrho cov cuab yeej siv yuav tsum yog ib feem ntawm ISO 13485 daim ntawv pov thawj zoo.

Phau Ntawv Qhia

Xaiv cov khoom tsim nyog rau kev cai hypotube pib nrog kev soj ntsuam zoo ntawm qhov chaw kho mob. Xav txog yam xws li xav tau yooj yim, torque, kink tsis kam, thiab biocompatibility. Ntsuas qhov zoo thiab qhov tsis zoo ntawm txhua tus neeg sib tw cov ntaub ntawv. Rau daim ntawv thov plawv, 316L feem ntau nyiam rau nws cov corrosion kuj. Yog xav tau superelasticity, xaiv Nitinol. Tsim cov qauv txiav kom ua tiav cov khoom siv. Prototype nyob rau hauv cov khoom xaiv thiab kev xeem ua haujlwm. Siv tau los ntawm kev ua kom muaj kev laus sai thiab kev sim biocompatibility. Sau cov ntaub ntawv xaiv cov khoom tsim nyog thiab cov txheej txheem tswj rau kev tswj hwm lub hom phiaj.

Tiag -Kev Paub Txog Ntiaj Teb

Peb qhov kev paub dhau los suav nrog ntau qhov haujlwm uas xaiv cov khoom tseem ceeb. Rau lub coronary stent xa system, peb siv 316L stainless hlau rau nws corrosion kuj thiab laser - txiav nws nrog ib tug kauv qauv los muab tau yooj yim. Nyob rau hauv ib tug neurovascular coil catheter, Nitinol raug xaiv rau nws kink rov qab, thiab peb optimized lub laser tsis tswj nws superelastic zog. Ib tus neeg siv khoom pib xaiv 304 stainless hlau tab sis hloov mus rau 17-7PH tom qab paub txog qhov xav tau kom muaj zog dua; peb kho cov txheej txheem kev kho cua sov kom ua tiav qhov xav tau. Cov xwm txheej no qhia txog qhov tseem ceeb ntawm kev xaiv cov khoom siv nrog cov khoom xav tau.

Summary & Elevation

Cov khoom xaiv yog lub hauv paus raws li kev cai hypotube kev ua tau zoo yog tsim. Cov khoom siv zoo, ua ke nrog kev txiav laser precision, tuaj yeem hloov lub raj yooj yim rau hauv lub neej -txuag ntaus ntawv. Raws li kev cuam tshuam ntawm cov hlab plawv ua ntau nyuaj, qhov kev thov rau cov khoom siv siab heev tsuas yog nce ntxiv. Kev cai hypotubes ua piv txwv txog kev sib koom ua tiav ntawm cov khoom siv tshawb fawb thiab kev tsim khoom siv tshuab, ua kom muaj kev tsim kho tshiab uas txhim kho kev saib xyuas neeg mob. Qhov kev sib koom ua ke no tseem yuav ua rau muaj kev vam meej hauv thaj teb, thawb cov kev txwv ntawm cov khoom siv cuam tshuam dab tsi tuaj yeem ua tiav.

Kev Cia Siab & Cov Lus Qhia

Cov khoom tsim kho yav tom ntej rau kev cai hypotubes yuav suav nrog siab -entropy alloys thiab bioresorbable hlau, muab cov kev sib txuas tshiab ntawm lub zog thiab biocompatibility. Cov neeg tsim khoom yuav tsum tau nqis peev rau hauv cov khoom siv tus yam ntxwv thiab ua cov kev tshawb fawb kom ua tiav cov kev nce qib no. Kev koom tes nrog cov kws tshawb fawb txog cov khoom siv thiab cov kws kho mob yuav ua kom ceev cov khoom siv tshiab. Tsis tas li ntawd, kev paub txog kev hloov pauv cov qauv ISO rau cov ntaub ntawv kho mob yog qhov tseem ceeb. Lub neej yav tom ntej ntawm kev cai hypotubes hauv kev cuam tshuam ntawm cov hlab plawv yog sib txuas nrog cov khoom siv tshiab, thiab cov neeg ua haujlwm hauv cheeb tsam no yuav tsim cov khoom siv kho mob tom ntej.
