Tshaj tawm ntawm Cov Lus Qhia

Peb txaus siab los ua kom paub cov "Precise" series ntawm qhov-zoo li semi-rigid qis qis raws li ultra-paj laser micro- txheej txheem thev naus laus zis. Peb tau ua tiav txoj kab uas hla sab nraud nyob rau hauv ± 0.01 millimeters. Lub laser- txiav qhov dav qhov tseeb ncav cuag ± 1.5 micrometers, thiab qhov roughness Ra yog tsawg dua lossis sib npaug li 0.1 micrometers. Cov khoom no tau dhau los ntawm ISO 13485 kev tswj hwm qhov system ntawv pov thawj. Nws tau khaws cov ntaub ntawv xoom tsis ua haujlwm hauv ib lab- voj voog bending qaug zog kuaj, cim tias kev tsim cov khoom muaj tseeb ntawm cov khoom tseem ceeb ntawm cov cuab yeej phais mob me me tau nkag mus rau hauv sub-micron era, muab lub hauv paus tsis tau pom dua los ntseeg siab rau siab -cov cuab yeej kho mob muaj tseeb.

Kev Tshawb Fawb thiab Kev Txhim Kho Tom Qab Kev Sib Tw

Kev tsim ib txwm siv ntawm qhov- cov raj zoo li lub ntsej muag ntsib peb qhov kev tsis sib haum xeeb loj: Ua ntej, muaj kev sib tw hauv kev tswj hwm thaj chaw thermal cuam tshuam thaum lub sij hawm laser txiav. Cov nyhuv thermal generated thaum lub sij hawm ua ib txwm ua rau cov kev hloov hauv microstructure ntawm cov khoom, ua rau micro- tawg thiab slag ntawm ntug ntawm lub qhov, uas dhau los ua lub hauv paus ntawm kev qaug zog tsis ua haujlwm. Qhov thib ob, muaj qhov tsis txaus ntawm qhov sib xws. Cov phab ntsa tuab ntawm lub raj sib txawv (feem ntau ± 0.03 millimeters) thiab qhov kev ua haujlwm tsis raug ua rau kev ua haujlwm sib txawv ntawm cov khoom siv, nrog rau kev khoov nruj thiab elastic rov qab tus nqi qhia txog kev tawg mus txog ± 15%. Thib peb, qhov zoo ntawm qhov chaw tsis ruaj khov. Cov burrs thiab microscopic irregularities ua rau muaj kev pheej hmoo ntawm kev sib txhuam kev puas tsuaj rau cov qauv thiab tseem cuam tshuam qhov smoothness ntawm daim duab. Cov ntaub ntawv kho mob qhia tau hais tias vim qhov tsis txaus ntawm kev tsim khoom raug, qhov tsis sib xws hauv kev tswj cov cuab yeej ua rau qhov nruab nrab nce ntawm 23% hauv lub sijhawm ua haujlwm rau cov kev phais vascular nyuaj thiab 40% nce hauv kev kawm nkhaus rau cov neeg ua haujlwm. Kev tshawb fawb engineering qhia tau hais tias yog tias qhov dav dav hloov pauv ntau dua ± 5 micrometers, qhov khoov lub vojvoog sib txawv yuav ncav cuag 18%, cuam tshuam loj rau kev kwv yees ntawm kev phais.

Core Technological Innovation

• Femtosecond laser ultra-txias tshuab:Siv lub ultra- laser system ceev nrog lub mem tes dav ntawm 300 femtoseconds, cov nyhuv "txias" ua tiav. Los ntawm kev tswj cov mem tes zog (0.5 - 20 μJ) thiab rov ua dua zaus (200 kHz - 2 MHz), thaj chaw thermal cuam tshuam yog tswj nyob rau hauv 2 micrometers, tshem tawm cov thermal micro- tawg tag. Tus kheej -tsim tsib-axis 联动 nanometer positioning platform muaj qhov tseeb qhov chaw ntawm ± 0.5 micrometers, kom ntseeg tau qhov tseeb replication ntawm complex groove qauv.
• Online adaptive them nyiaj system:Kev koom ua ke ntawm laser interferometer thiab siab -ceev CCD qhov pom kev, nws saib xyuas cov yeeb nkab cov khoom deformation thiab zawj dav hloov pauv thaum lub sijhawm txiav cov txheej txheem. Raws li kev kawm tshuab algorithms, lub kaw lus kho qhov txiav tsis ua haujlwm ib zaug txhua millisecond, dynamically compensating rau cov uas tsis ua los ntawm cov khoom thermal expansion thiab mechanical vibration. Cov cuab yeej no txo ​​cov qhov dav dav hloov pauv los ntawm kev lag luam nruab nrab ntawm ± 8 micrometers mus rau ± 1.5 micrometers, thiab batch sib xws tus qauv sib txawv ntawm 0.25 txog 0.08.
• Multi-level composite nto txheej txheem:Innovatively tsim ib tug peb - theem ua ntws ntawm "electrochemical polishing - magnetorheological polishing - plasma tu." Electrochemical polishing tshem tawm 5 - 8 micrometers ntawm cov khoom saum npoo kom tshem tawm cov cim txiav; Magnetorheological polishing ua tiav nanometer-theem refinement, nrog rau qhov roughness Ra tus nqi poob los ntawm 0.4 micrometers mus rau hauv qab 0.1 micrometers; Plasma tu kom huv si tshem tawm cov organic residues, txo lub zog saum npoo mus rau 18 mN / m, txo cov ntaub so ntswg adhesion.

Mechanism ntawm Action

Tus nqi tseem ceeb ntawm micrometer- theem precision yog tshwm sim nyob rau hauv peb lub cev yam: Nyob rau hauv lub kinematic theem, lub precisely tswj qhov dav thiab suab kom paub meej tias cov dabtsi yog khoov nruj yog linearly kwv yees, thiab lub kaum sab xis dabtsi yog khoov muaj ib tug nruj proportional kev sib raug zoo nrog cov duab xaav (linear℃R²> 0.998); Nyob rau hauv cov txheej txheem, cov txheej txheem phab ntsa thickness faib (kev kam rau ua ± 0.01 millimeters) optimizes kev ntxhov siab faib, txo cov kev ntxhov siab concentration coefficient los ntawm cov tsoos manufacturing ntau yam ntawm 3.2-4.5 mus rau 1.8-2.2, thiab ua rau lub neej qaug zog ntau tshaj peb zaug; Ntawm cov kua dej dynamics, daim iav zoo li qhov chaw txo qhov tsis kam ntawm cov ntshav khiav, thiab nyob rau hauv lub simulated vascular ib puag ncig, lub siab poob yog txo los ntawm 42%, kev txhim kho cov efficiency ntawm kev sib piv tus neeg sawv cev. Lub interface ntawm qhov tsis muaj cua sov cuam tshuam cheeb tsam tsim los ntawm femtosecond laser ua tsub kom cov khoom qaug zog txwv rau 2.5 npaug ntawm cov khoom ib txwm muaj.

Kev txheeb xyuas qhov ua tau zoo

Nyob rau hauv cov qauv kev sim platform, qhov precision tubular tsim ua tau zoo heev: nyob rau hauv qhov kev ntsuam xyuas nruj, lub coefficient ntawm variation nyob rau hauv batch txo los ntawm 12.5% ​​mus rau 2.1%; Nyob rau hauv qhov kev ntsuam xyuas elastic rov qab, tom qab khoov los ntawm ± 90 degree, cov duab rov qab raug mus txog 99.7% (kev lag luam nruab nrab 97%); Nyob rau hauv qhov kev xeem torque kis tau tus mob, qhov 1: 1 torque fidelity yuam kev yog tsawg tshaj li 0.5 degree. Kev ntsuas nrawm nrawm (khoov los ntawm ± 90 degree, ntawm qhov zaus ntawm 5Hz) pom tias cov khoom khaws cia 95% ntawm nws qhov kev ua tau zoo pib tom qab 2 lab cycles, deb tshaj qhov kev lag luam tus qauv ntawm 500,000 cycles. Ntau-cov kev tshawb fawb hauv chaw kho mob suav nrog thaj chaw xws li neurointervention thiab kev cuam tshuam ntawm cov hlab plawv: hauv kev phais intracranial aneurysm embolization, lub sijhawm rau microcatheter kom ncav cuag lub hom phiaj tau luv los ntawm 35%; nyob rau hauv kev cuam tshuam rau tag nrho cov occlusion ntawm coronary hlab ntsha, cov cuab yeej ua tau zoo nce los ntawm 78% mus rau 94%; postoperative ua raws-up qhia tau hais tias qhov tshwm sim ntawm vascular raug mob vim tsis raug cov cuab yeej siv tau txo los ntawm 71%.

Kev tshawb fawb thiab kev loj hlob Strategy thiab Philosophy

Peb ua raws li kev tsim lub tswv yim ntawm "precision txhais cov txiaj ntsig," thiab tau tsim ib qho peb - hauv -ib qho kev tsim khoom ntawm DMA (Tsim - Cov Khoom Siv - Txheej Txheem). Nyob rau theem tsim, peb txais yuav txoj kev tsim qauv zoo raws li kev soj ntsuam kev ua siab ntev, thiab siv Monte Carlo simulation los kwv yees qhov cuam tshuam ntawm kev tsim khoom sib txawv ntawm kev ua haujlwm; nyob rau ntawm cov khoom theem, peb tau tsim ib lub chaw soj nstuam sib koom nrog cov chaw tsim khoom tshwj xeeb los tsim laser- txiav- cov kav dej tshwj xeeb, tswj cov phab ntsa thickness uniformity nyob rau hauv ± 0.005 millimeters; nyob rau theem txheej txheem, peb tau tsim cov qauv ntxaib digital ntawm cov txheej txheem tsis thiab cov yam ntxwv zoo kom ua tiav qhov kev txawj ntse. Peb tau nqis peev pab rau kev tsim kho qhov kub thiab txias tsis tu ncua ultra- kev cob qhia huv (nrog qhov kub thiab txias hloov ntawm ± 0.1℃thiab av noo hloov pauv ntawm ± 2%, kev huv huv ISO 4), muab kev lees paub ib puag ncig rau sub-micron- qib kev tsim khoom. Nyob rau tib lub sijhawm, peb siv "zero defect" kab lis kev cai, nce ib qho -time pass rate (FPY) mus rau 99.99% thiab tswj qhov tsis xws luag (DPPM) qis dua 10.

Yav tom ntej Outlook

Lub hauv paus tseem ceeb tom ntej hauv kev tsim khoom yog nanometer-theem raug thiab ntse tiag tiag- tswj lub sijhawm. Peb tab tom txhim kho nanomachining thev naus laus zis raws li electron beam lithography, txhawm rau ua kom qhov tseeb txiav mus rau ± 0.001 millimeters; tshawb nrhiav atomic txheej deposition nto hloov kho rau daim ntawv 5-10 nanometer functional coatings ntawm lub raj phab ntsa; thiab tsim cov ntse laser txiav tshuab uas tuaj yeem saib xyuas kev txiav zoo hauv lub sijhawm tiag tiag los ntawm fiber ntau grating sensors thiab hloov kho qhov tsis muaj. Hauv xyoo 2028, peb yuav tso cov neeg txawj ntse hauv qab-cov neeg coj ua nrog "tus kheej-sensing" muaj peev xwm, uas muaj cov fiber ntau optic sensor network los saib xyuas cov kab sib faib thiab qhov kub thiab txias hauv lub sijhawm. Saib ntxiv tom ntej, kev tsim cov kev tswj xyuas zoo raws li kev ntsuas quantum precision yuav ua tiav "atomic{11}}theem" ​​qhov tseeb, ua rau nws ua tau rau ib leeg -kev cuam tshuam ntawm tes thiab ua rau lub sijhawm tshiab ntawm cov tshuaj precision.
