Cheebtsam engineers nquag ntsib cov ntaub ntawv ntsig txog qhov mob thaum lub sij hawm laser-cut hypotube txoj kev loj hlob. Ib qho hlau tsis tuaj yeem ua tiav tag nrho cov txheej txheem kev xav tau. Stainless hlau hypotubes qhia tau zoo heev torsional zog tab sis txwv elastic rov qab muaj peev xwm. Nitinol coj cov cuab yeej superelastic, tab sis laser ua qhov ntsuas qhov rais yog nqaim thiab cov nqi tsim khoom nce ntau. Cobalt-chromium L605 muab kev tiv thaiv qaug zog, thaum cov khoom siv raw khoom siv sij hawm ntev dua. Kev xaiv cov khoom tsis raug ua rau cov txiaj ntsig tsis ua raws li cov txiaj ntsig kev qaug zog, cov khoom tawg thaum ntxov, lossis tsis txaus biocompatibility. Cov kev ua yuam kev zoo li no ua rau muaj kev hloov pauv tus nqi tsim nyog, ncua sijhawm ISO 13485 daim ntawv pov thawj kev nce qib, thiab ncua sijhawm kho cov cuab yeej kho mob txhais lus rau cov hlab plawv, tso zis thiab neuro-interventional tej yaam num.

Lub hauv paus ntsiab lus ua haujlwm tom qab cov khoom-tus qauv sib piv rau laser-txiav hypotube: cov khoom siv hauv lub raj txhais tau hais tias cov khoom siv kho qhov muag, thiab cov qauv txiav laser hloov cov raj-phab ntsa hauv zos. Cov khoom siv laser tsim cov slits meej nrog qhov tsawg kawg nkaus 0.012 hli kerf dav ntawm niam txiv tubing xws li Ø0.20 mm-20 mm. Cov ntaub ntawv tawm los lub zog, elastic modulus thiab qaug zog tiv thaiv teeb tsa lub siab txwv rau qhov yooj yim npaum li cas tuaj yeem ua tiav los ntawm kev txiav geometry. Txawm tias zoo tib yam kauv txiav layout, 316 stainless hlau hypotube thiab Nitinol hypotube qhia tau hais tias txawv kiag li bending rebound tus cwj pwm. Cov neeg tsim qauv yuav tsum ua kom cov khoom siv hauv qab cov yam ntxwv nrog laser txiav layout kom ua tiav qhov kev xav tau thawb-muaj peev xwm, taug qab thiab tiv thaiv kev ua haujlwm rau percutaneous transluminal coronary angioplasty thiab lwm yam kev xa tawm me me.

Tej yam khoom siv rau laser-txiav hypotube npog plaub tsev neeg loj. 304 stainless hlau (1.4301) muaj cov nqi sib npaug thiab ua haujlwm tau zoo, dav siv rau cov khoom siv endoscopic dav dav. 316 stainless hlau (1.4401) muab kev tiv thaiv corrosion zoo tshaj, haum rau cov khoom siv urinary interventional tiv tauj lub cev cov kua dej ua ntej . 175S‑7PH (AM) ultra-high tensile lub zog tom qab kev kho cua sov, zoo tagnrho rau me me-inch Ø0.20 mm-scale micro hypotube. Nitinol coj lub npe nrov superelasticity, feem ntau siv rau hauv cov khoom siv neuro-vascular uas yuav tsum tau rov ua dua tshiab. L605 cobalt-chromium alloy excels ntawm cyclic dabtsi yog khoov qaug zog kev ua tau zoo rau lub sij hawm ntev indwelling khoom Cheebtsam. Txhua yam khoom ua haujlwm nrog txuas txuas ntxiv, cuam tshuam kauv, radial thiab bespoke kev cai laser txiav qauv.

Kev taw qhia kev ua haujlwm rau cov khoom siv-oriented hypotube manufacturing pib nrog kev xav tau decomposition. Qhia meej txog qhov kawg-siv qhov chaw kho mob, lub hom phiaj ntsuas ntsuas, qhov txwv sab hauv sab hauv thiab cov kev qhia txog biocompatibility. Xaiv cov niam txiv tube alloy thiab xa 2D / 3D kos duab lossis kuaj lub cev rau cov tuam txhab tsim khoom. Kho laser txiav fais fab, ceev thiab kerf teeb raws li cov khoom siv; Nitinol xav tau kev ntsuas tshwj xeeb kom tsis txhob muaj cua sov ua rau thaj tsam brittleness. Ua tiav kev kho mob tom qab txiav, tshem tawm cov micro-burrs uas tsim los ntawm cov npoo. Ua kom tiav txhua yam validation: torque hloov mus kuaj, kink kuj ntsuas thiab cyclic dabtsi yog khoov qaug zog xeem. Txais ISO 13485-raws li cov ntaub ntawv tsim khoom, xaiv cov thawv ntim khoom lossis cov neeg siv khoom tshwj xeeb ntim ua ntej xa khoom.

Kev paub txog kev ua haujlwm hauv teb tau nthuav tawm cov khoom siv rov ua dua tshiab. Ntau tus neeg siv khoom xaiv Nitinol tsuas yog rau "siab yoog raws", tsis quav ntsej nws qhov kev nruj dua qub; kawg hypotube tseem nruj heev rau ultra-tortuous neuro-vsel txoj kev. Qee qhov haujlwm xaiv 304 stainless hlau rau kev siv lub voj voog ntev-ntev-tseem ceeb, ua rau lub hauv paus tawg tawg thaum lub sijhawm kuaj. Thaum sib tov ntau cov qauv txiav ntawm ib lub raj, cov kws ua haujlwm yuav tsum ntsuas cov khoom siv qaug zog ntawm qhov chaw hloov pauv. Nws raug nquahu kom khiav cov qauv kev sim siv cov khoom siv raw, tsis yog ua kom tiav simulation nkaus xwb. Cov ntaub ntawv kos duab yuav tsum qhia meej tias qib alloy, lub xeev kev kho cua sov thiab kev tso cai kerf ntau yam.

Los xaus, cov khoom siv substrate ua raws li lub hauv paus ntawm laser-txiav hypotube kev ua tau zoo. Laser slit geometry optimizes mechanical output, tseem tsis tuaj yeem kov yeej cov kev txwv ntawm cov khoom siv hauv paus. 300-series stainless hlau, nag lossis daus-hardening hlau, Nitinol thiab cobalt-chromium txhua tus nyob hauv thaj chaw thov sib txawv. Material-pattern kev sib koom tes tsim yog ib qho tseem ceeb rau tsim nyog catheter xa system Cheebtsam. Cov txheej txheem kev tswj xyuas kom zoo raws li ISO 9001: 2015 thiab ISO 13485 tiv thaiv cov khoom siv cuam tshuam tsis ua haujlwm.

Yav tom ntej cov cuab yeej kho mob miniaturization sib thawb hypotube txheej kab mus rau me me Ø0.20 mm qib. Cov neeg muag khoom yuav tsum tau nthuav dav ultra-thin-wall multi-alloy laser-txiav kev muaj peev xwm. Downstream R & D pab pawg yuav tsum koom nrog cov khoom siv hypotube nyob rau hauv lub tswv yim tsim thaum ntxov, tsis yog kev txiav txim siab ntawm cov khoom siv tom qab kos duab tiav. Kev ntsuam xyuas thaum ntxov ntawm kev sib koom ua ke txo qis kev pheej hmoo rov tsim dua tshiab thiab ua kom cov khoom lag luam cuam tshuam tshiab rau aortic aneurysm, peripheral vascular thiab imaging-guided surgical platforms.
