Pain Points

Ntau cov khoom siv cuam tshuam xav tau cov khoom sib txawv ntawm cov raj sib txawv. Qhov kawg ntawm kev sib txuas nrog kov yuav tsum muaj lub zog hloov pauv siab thiab thawb-ua haujlwm; lub distal tip mus rau hauv tib neeg cov hlab ntsha xav tau cov mos mos kom tsis txhob raug mob hlab ntsha. Uniform nruam kauv hypotube tsis tuaj yeem paub tseeb qhov tawv tawv gradient raws axial kev taw qhia. Tej yam yooj yim uas tsis yog-txiav cov tubing ua rau siab sib thooj tab sis tsis tuaj yeem soften qhov distal. Yog tias tsis muaj kev tswj hwm gradient-stiffness qauv, cov neeg ua haujlwm ntsib qhov tsis zoo ntawm qhov kev taug qab nyob rau hauv tortuous peripheral thiab cerebral vasculature. Cov neeg tsim khoom siv tau ntsib teeb meem thaum tsim lub plab aortic aneurysm kho cov cuab yeej thiab neuro-interventional xa catheters. Kev sib xyaw ua ke ib txwm siv los ntawm kev koom nrog ntau qhov sib cais cov ntu qhia txog kev sib txuas ntxiv cov pob qij txha, ua rau muaj kev pheej hmoo tsis ua haujlwm thiab kev sib dhos nyuaj. Cov neeg tsim qauv cia siab tias yuav ua tiav seamless one-piece hypotube nrog kev hloov pauv hloov pauv tsuas yog los ntawm kev kho laser txiav nta.

Txoj Cai Ua Haujlwm

Kev cuam tshuam kauv hlais hypotube hloov kho cov kab nrib pleb tas li los ntawm kev khaws cov av tsis tu ncua ntawm cov hlau tsis tu ncua raws li laser kauv kerfs. Base tubing ranges Ø0.20 mm-20 mm, qhov tsawg kawg nkaus kerf dav txog 0.012 mm, cov ntaub ntawv muaj xws li 304, 316L stainless hlau, 17-7PH, Nitinol thiab L605. Uncut av seem khaws cov tube puag ncig rigidity, txhim kho torque kis tau tus mob thiab muaj peev xwm tiv thaiv kev sib tsoo-deformation. Slotted kauv ntu xa bending yooj. Los ntawm kev hloov av sib nrug, thaj av ntev thiab kauv suab los ntawm qhov ze mus rau qhov kawg, engineers tsim seamless axial stiffness gradient. Cov cheeb tsam ze ze tau txais qhov sib nrug luv luv, cov av tsis tau txiav ntev kom tswj tau qhov siab nruj. Cov cheeb tsam Distal nce kauv qhov kev faib ua feem thiab ua kom luv thaj av kom nce softness. Kev sib hloov quab yuam dhau los ntawm cov hlau seem seem thiab cov av tsis tau txiav mus rau lub taub hau. Khoov deformation concentrates ntawm kauv slotted thaj chaw thaum cov av khoom tiv thaiv ntau dhau torsional winding. Tag nrho cov yam ntxwv ntawm lub tshuab yog txhais los ntawm laser txiav geometry ntawm ib leeg monolithic raj substrate.
