Kev Tshaj Tawm Txog Kev Ua tiav

Peb tau ua tiav kev lag luam ntawm micron-theem ultra-kev tsim khoom siv thev naus laus zis hauv laparoscopic shaving hniav thiab pib "Jingwei" series ntawm siab- cov hniav zoo. Cov khoom no tau txais kev tsim ntawm tus kheej "tsib-axis linkage - ultrasonic-pab" kev siv tshuab ua ke, tswj qhov kev ua yuam kev ncaj ntawm ntug hniav hauv 0.5μm / 10mm thiab stabilizing ntug vojvoog ntawm 3 ± 0.5μm, mus txog qib. Muaj ntawv pov thawj los ntawm ISO 13485 cov txheej txheem zoo, tus qauv sib txawv ntawm cov khoom sib xws ntawm cov khoom yog tsawg dua 0.15, ua tiav kev dhia ntawm "handcraft-level precision" mus rau "instrument-level precision," ua tau raws li qhov xav tau ntawm cov cuab yeej phais hauv cov neeg hlau -pab kev phais tsawg kawg nkaus.

Kev tshawb nrhiav thiab kev txhim kho keeb kwm mob ntshav qab zib

Kev tsim khoom tsis txaus ntawm cov txheej txheem txheej txheem ua rau peb qhov teeb meem loj hauv kev kho mob: Ua ntej, qhov sib txawv ntawm cov hniav ntawm ntug, nrog rau lub kaum sab xis ntawm cov hniav nyob rau hauv tib batch fluctuating los ntawm ± 3 degree, ua rau cov kev ua tau zoo txiav unpredictable; Thib ob, kev tswj tsis zoo ntawm qhov chaw roughness, nrog Ra qhov tseem ceeb feem ntau yog li ntawm 0.4 txog 0.8 μm, ua rau muaj kev pheej hmoo ntawm cov ntaub so ntswg kev puas tsuaj; thib peb, tsis txaus dynamic tshuav qib, ua rau muaj kev co ntau heev thaum lub sij hawm siab -kev sib hloov ceev thiab cuam tshuam rau kev ua haujlwm ruaj khov. Kev tshawb fawb engineering qhia tau hais tias ntawm qhov kev sib hloov ceev ntawm 4000 rpm, cov hniav nrog qhov tsis sib npaug ntau tshaj 0.5 g·mm yuav tsim cov radial vibrations nrog lub amplitude ntau dua 20 μm, uas yog lub ntsiab lub cev ua rau "plam jitter" thiab "ntau txiav." Cov txheej txheem tsim khoom tam sim no tso siab rau kev sib tsoo ntawm cov neeg ua haujlwm txawj, ua rau nws nyuaj los xyuas kom meej cov khoom sib xws.

Core Technological Innovation

• Tsib -axis ultrasonic vibration-pab machining system:Qhov no innovatively combines ultrasonic kev co (nrog ib zaus ntawm 40 kHz thiab amplitude ntawm 5 μm) nrog tsib -axis precision machining. Ultrasonic vibration transforms cov txheej txheem txiav los ntawm kev txiav txuas ntxiv mus rau micro- txiav, txo cov txiav quab yuam los ntawm 60% thiab ua tiav "tsis muaj burrs, tsis ua haujlwm- txheej tawv" ua. Tus kheej- tsim cov cuab yeej tsim txoj hauv kev tuaj yeem them nyiaj rau qhov kev sib tw hauv lub sijhawm raws li cov cuab yeej hnav, kom ntseeg tau qhov sib xws hauv batch ntau lawm.
• Online optical soj ntsuam thiab kaw -loop them nyiaj siv tshuab:Dawb lub teeb interferometers thiab laser confocal microscopes tau koom ua ke rau hauv cov kab ntau lawm kom ua tiav 100% kev tshuaj xyuas online thaum lub sijhawm machining txheej txheem. Lub kaw lus ua ib qho kev ntsuas tag nrho (suav nrog lub vojvoog ntawm ntug, lub kaum sab xis, lub kaum sab xis, roughness, thiab lwm yam., tag nrho 12 qhov tsis sib xws) rau txhua 10 daim ntawv ua tiav, thiab cov ntaub ntawv raug xa rov qab mus rau CNC system hauv lub sijhawm tiag tiag rau kev them nyiaj thiab kev hloov kho, tsim "machining - kev ntsuas - nyiaj" kaw.
• Tsawg-kub ion beam polishing txheej txheem:Argon ion beams yog siv los ua qhov kawg polishing ntawm cov hniav ntawm qhov kub ntawm -150℃. Lub zog ion yog tswj nyob rau hauv thaj tsam ntawm 50-150 eV, thiab los ntawm lub cev sputtering, 2-3 μm ntawm cov khoom raug tshem tawm ntawm qhov chaw kom tshem tawm cov txheej txheem kev ntxhov siab los ntawm kev siv tshuab polishing. Cov txheej txheem no txo ​​cov nplaim roughness Ra tus nqi qis dua 0.05 μm, ua tiav daim iav zoo li qhov kawg, thiab ib txhij ua cov txheej txheem kev ntxhov siab, txhim kho lub neej qaug zog.

Mechanism ntawm Action

Qhov zoo ntawm cov khoom siv roj ntsha ntawm ultra- precision manufacturing yog manifested nyob rau hauv peb yam: nyob rau hauv cov ntaub so ntswg sib cuam tshuam theem, daim iav-zoo li nto txo ​​cov neeg kho tshuab interlocking cov ntaub so ntswg thiab qis cell adhesion los ntawm 80%, yog li txo cov ntaub so ntswg traction puas; nyob rau theem txiav tshuab, tswj cov hniav geometry precisely (nrog lub kaum sab xis ntawm 12℃± 0.5℃thiab lub kaum sab xis ntawm 8℃± 0.5 degree) optimizes cov kev taw qhia ntawm txiav quab yuam, hloov 90% ntawm lub zog rau hauv kev txiav suab thiab tsuas yog 10% rau hauv radial siab, yog li kev tiv thaiv ib txwm muaj. ntawm cov kua dej dynamics, cov npoo du pab tsim cov laminar ruaj khov ntawm cov dej hauv dej, tshem tawm cov ntaub so ntswg sai sai los ntawm kev saib thiab txhim kho kev phais kom pom tseeb. Kev txhim kho nyob rau hauv dynamic tshuav nyiaj li cas qhov tseeb (mus txog G1.0 qib) xyuas kom meej tias cov hniav vibration displacement yog tsawg tshaj li 2 μm ntawm ib tug ceev ntawm 10,000 rpm, ua tiav kev tswj ruaj khov akin rau "hnav li ntse li riam."

Kev txheeb xyuas qhov ua tau zoo

Nyob rau hauv cov txheej txheem xeem platform, lub precision hniav qhia tau zoo heev ua tau zoo: nyob rau hauv lub ntug sharpness xeem, lub zog yuav tsum tau txiav cov qauv xeem zaj duab xis tsuas yog 1.8N (kev lag luam nruab nrab 3.5N); Kev kuaj lub neej qaug zog tau pom tias tom qab ua haujlwm tas li rau 6 teev nyob rau hauv kev simulated phais mob, lub vojvoog ntawm ntug tsuas yog nce los ntawm 3.1μm mus rau 4.5μm (ib txwm cov hniav nce ntawm 5μm mus rau 12μm); Qhov kev ntsuam xyuas cytocompatibility qhia tau hais tias qhov ciaj sia taus ntawm L929 hlwb ntawm cov polished nto mus txog 98.7%, ho siab dua 92.1% ntawm cov tsoos nto. Ib txoj kev tshawb fawb soj ntsuam yav tom ntej suav nrog 120 tus neeg mob ntawm lub hauv caug arthroscopic phais, thiab cov txiaj ntsig tau pom tias qhov tshwm sim ntawm cov pob txha subchondral nyob rau hauv pab pawg siv cov hniav precision txo los ntawm 21% mus rau 4%; qhov nruab nrab ntawm cov pob txha mos raug txo los ntawm 42% hauv MRI kev soj ntsuam ntawm 3 lub hlis tom qab-kev ua haujlwm; tus kws kho mob qhov kev ua haujlwm tau qhab nia (ntawm 10-point scale) tau nce los ntawm 7.2 mus rau 9.1, nrog rau kev txhim kho tseem ceeb tshaj plaws hauv "txiav tswj" thiab "tes hnov ​​​​kev ruaj ntseg."

Kev tshawb fawb thiab kev loj hlob Strategy thiab Philosophy

Peb ua raws li tus nqi tseem ceeb ntawm "Precision defines efficacy" thiab tau tsim lub tswv yim tsim khoom uas sib koom ua ke TAP (Technology - Art -} Philosophy) ua trinity. Ntawm kev ua haujlwm pem hauv ntej, peb tau tsim cov qauv lej thiab lub cev, suav cov kev cai kho mob rau hauv 36 engineering tsis thiab decomposing lawv cov kauj ruam los ntawm kev ua cov txheej txheem tshwj xeeb los ntawm Kev Ua Haujlwm Zoo (QFD). Nyob rau hauv kev kos duab pem hauv ntej, peb tau cog ib pab neeg ntawm "craftsman engineers," hloov lub "kov" ntawm tsoos craftsmanship rau hauv quantifiable tus lej tswj cov lus qhia. Nyob rau hauv lub tswv yim pem hauv ntej, peb nrhiav "kev ua tsis zoo tag nrho," lees paub qhov tsis muaj peev xwm ntawm kev tsim cov khoom lag luam tab sis ua rau lawv nyob rau hauv cov kab mob lom neeg tsis txaus ntseeg los ntawm Kev Tswj Xyuas Txheej Txheem Txheej Txheem (SPC). Peb tau nqis peev hauv kev tsim lub ntiaj teb thawj zaug ultra-kev cob qhia huv rau cov cuab yeej phais mob me me (ISO 5 qib), nrog rau qhov kub thiab txias tswj tsis pub dhau ± 0.5℃thiab av noo hloov pauv hauv ± 3%, muab kev lees paub ib puag ncig rau micron- qib kev tsim khoom.

Yav tom ntej Outlook

Lub hauv paus tseem ceeb tom ntej hauv kev tsim khoom yog "atomic-theem manufacturing." Peb tab tom txhim kho atomic deposition kho thev naus laus zis raws li kev tsom ion beams (FIB), uas tuaj yeem ua tiav atomic - qib cov khoom ntxiv ntawm cov teeb meem hauv zos ntawm ntug hniav; tshawb xyuas cov kab hluav taws xob-induced deposition (EBID) los npaj nanostructures thiab tsim ib qho array ntawm nano-kab nrog kev taw qhia ntawm cov hniav nto kom ua tiav "cov qauv superlubricity"; thiab txhim kho quantum dot ntsuas system los ntsuas sub-nanometer scale topography siv cov nyhuv quantum tunneling. Xyoo 2028, peb yuav tso tawm "adaptive stiffness" blades, integrating adjustable stiffness structures in the blade body through micro-electromechanical systems (MEMS), enabling the same blade to switch of rigid mode (rau txiav pob txha) thiab saj zawg zog hom (rau txiav cov nqaij mos). Saib ntxiv tom ntej, "zero-} kam rau ua" kev tsim khoom raws li kev ntsuas quantum precision yuav rov txheeb xyuas cov ciaj ciam ntawm cov cuab yeej phais thiab ua tiav qhov tseeb "molecular{11}}level" kev phais qhov tseeb.
