Pain Points

Pushability yog lub peev xwm los xa cov quab yuam ntev los ntawm qhov kawg ntawm qhov kawg mus rau qhov xaus ntawm lub catheter, ua rau nws mus dhau los ntawm cov kab mob resistant los yog cov hlab ntsha nruj. Hauv ntau qhov xwm txheej cuam tshuam, xws li hla tag nrho cov occlusions ntev los yog navigating heev tortuous peripheral hlab ntsha, tsis txaus pushability ua rau ntaus ntawv prolapse los yog ua tsis tau tejyam mus cuag lub hom phiaj. Standard polymer shafts feem ntau buckle nyob rau hauv compressive loads, thaum cov pa hlau raj tej zaum yuav nruj heev, ua rau cov hlab ntsha raug mob. Kev cai hypotubes hais txog qhov no los ntawm kev muab cov khoom sib npaug ntawm kem lub zog thiab hloov tau yooj yim, tab sis ua tiav qhov zoo tshaj plaws pushability profile yuav tsum tau ua tib zoo tsim thiab xaiv cov khoom siv.

Txoj Cai

Lub hauv paus ntsiab lus ntawm pushability nyob rau hauv kev cai hypotubes revolves nyob ib ncig ntawm kem lub zog thiab buckling kuj. Laser- txiav cov qauv tuaj yeem tsim los txhim kho qhov ntev ntev thaum tuav qhov tsim nyog tau yooj yim. Piv txwv li, ib tug qauv nrog longitudinal struts interspersed nrog kauv txiav muab ib tug txha nraub qaum rau pushability, thaum lub kauv seem cia khoov. Cov khoom siv xaiv yog qhov tseem ceeb: 304 stainless hlau muaj lub zog zoo thiab tsim tau, 316L muab kev tiv thaiv corrosion ntau dua, thiab Nitinol muab cov superelastic rov qab los ntawm compression. Cov txheej txheem laser txiav, nrog nws cov nplua kerf (0.012 hli yam tsawg kawg nkaus), xyuas kom meej tias cov txheej txheem kev ncaj ncees yog khaws cia, cia lub hypotube xa cov quab yuam zoo yam tsis muaj buckling.

Kev faib khoom siv

Manufacturing kev cai hypotubes rau pushability yuav precision laser tej tshuab muaj peev xwm ntawm ua intricate qauv nrog siab repeatability. Tube straightening thiab kos duab cov cuab yeej ua kom lub hauv paus raj muaj qhov ntev ntev. Ncej- kev ua tiav suav nrog kev sib tsoo nruab nrab kom ua tiav cov kab npoo sab nraud thiab electropolishing rau qhov smoothness. Cov khoom siv kuaj xws li compression testers thiab buckling fixtures yog siv los ntsuas qhov kev txhawb nqa. Tag nrho cov txheej txheem yuav tsum ua raws li ISO 13485 cov txheej txheem tswj kev ua haujlwm kom ntseeg tau tias cov cuab yeej muaj kev nyab xeeb thiab ua haujlwm tau zoo.

Phau Ntawv Qhia

Txhawm rau tsim ib qho kev cai hypotube nrog kev ua kom pom kev zoo, ua ntej txheeb xyuas qhov yuav tsum tau muaj zog ntawm kab thiab qhov siab tshaj plaws sab nraud. Xaiv cov khoom siv nrog siab elastic modulus, xws li 304 stainless hlau. Tsim ib qho qauv txiav uas suav nrog qhov kev ncua ntev, xws li alternating kauv thiab axial txiav. Siv finite keeb tsom xam los simulate buckling nyob rau hauv load. Prototypes thiab kuaj cov qauv nyob rau hauv compressive rog los soj ntsuam pushability. Iterate tus tsim kom sib npaug pushability nrog yooj thiab torque. Thaum kawg, siv tau tus qauv tsim los ntawm lub rooj ntev zaum thiab kuaj tsiaj, thiab sau tag nrho cov txheej txheem rau kev tswj xyuas.

Tiag -Kev Paub Txog Ntiaj Teb

Hauv peb qhov kev paub dhau los, tus neeg siv khoom tsim cov khoom siv hluav taws xob peripheral atherectomy ntsib teeb meem pushability thaum hla cov kab mob hnyav heev. Peb rov tsim kho lub hypotube nrog cov qauv uas muaj cov txuas txuas txuas txuas txuas ntxiv, uas ua rau muaj zog ntxiv ntawm 35% yam tsis muaj kev cuam tshuam yooj yim. Lwm qhov project cuam tshuam nrog ib txoj hlab ntsha neurovascular uas xav tau kev thawb los ntawm cov hlab ntsha hauv hlwb. Los ntawm kev siv Nitinol thiab cov qauv kev cai nrog ntau qhov sib txawv kauv suab, peb ua tiav qhov tsim nyog pushability thaum tswj kev taug qab. Cov xwm txheej no qhia txog qhov tseem ceeb ntawm cov khoom siv thiab cov qauv kev sib koom ua ke hauv kev ua tiav qhov xav tau kev txhawb nqa.

Summary & Elevation

Kev cai hypotubes tau nce tus qauv ntawm kev thawb hauv cov khoom siv cuam tshuam, ua rau cov kws kho mob kho cov kab mob uas tsis tuaj yeem siv tau yav dhau los. Lub peev xwm los txhim kho kem lub zog rau hauv lub taub hau hloov tau yog qhov ua pov thawj rau lub zog ntawm laser txiav tshuab thiab cov khoom siv science. Qhov kev nce qib no tsis tsuas yog txhim kho cov txheej txheem kev ua tiav tab sis kuj tseem txhim kho kev nyab xeeb ntawm cov neeg mob los ntawm kev txo qis qhov xav tau ntawm kev ua nruj ua tsiv. Raws li thaj tsam ntawm kev kho mob tsawg kawg nkaus tau nce mus, kev cai hypotubes tseem yuav yog lub hauv paus ntawm kev tsim kho tshiab.

Kev Cia Siab & Cov Lus Qhia

Yav tom ntej tiam sis nyob rau hauv kev cai hypotube pushability yuav muaj feem xyuam nrog hybrid cov ntaub ntawv thiab adaptive qauv uas hloov nruj nyob rau hauv teb rau physiological tej yam kev mob. Cov neeg tsim khoom yuav tsum tshawb nrhiav cov txheej txheem tsim khoom zoo xws li 3D laser luam ntawv los tsim cov duab geometry ntau dua. Kev nqis peev hauv R&D rau cov alloys tshiab nrog lub zog siab dua - rau - qhov hnyav piv kuj raug pom zoo. Kev koom tes nrog cov kws kho mob kom nkag siab txog cov nuances ntawm kev nkag mus tob tob yuav ua rau muaj kev txhim kho ntxiv. Raws li kev tswj hwm toj roob hauv pes hloov zuj zus, kev tswj hwm qhov system zoo yuav yog qhov tseem ceeb. Kev nrhiav qhov zoo tshaj plaws pushability yog tsis tu ncua, thiab kev cai hypotubes yog coj txoj kev.
