Pain Points

Kev cuam tshuam ntawm cov hlab plawv nthuav tawm cov khoom siv rau cov khoom siv hluav taws xob dynamic thiab ib puag ncig corrosive lom. Stainless hlau hypotubes yuav corrode lub sij hawm, tso ions uas provoke inflammatory teb. Nitinol, thaum biocompatible thiab saj zawg zog, yog kim thiab nyuaj rau laser - txiav yam tsis tsim ib txheej recast. Braid cov ntaub ntawv zoo li stainless hlau kuj tuaj yeem corrode, thiab cov tsho polymer tuaj yeem muag ntawm lub cev kub, txo qis kev sib kis. Kev xaiv cov khoom siv tsis raug ua ke tuaj yeem ua rau lub cuab yeej tsis ua haujlwm, ua rau tus neeg mob raug mob, thiab rov qab tau nyiaj ntau. Yog li, kev xaiv cov khoom siv yog qhov mob tseem ceeb uas yuav tsum tau ua tib zoo xav.

Txoj Cai Ua Haujlwm

Nyob rau hauv lub braid reinforced hypotube, txhua yam khoom plays lub luag hauj lwm sib txawv. Cov khoom siv hypotube yuav tsum muaj lub zog qaug zog thiab tsim nyog elasticity . 304 stainless hlau yog ib qho rau nws qhov sib npaug ntawm cov khoom, thaum 316L muaj kev tiv thaiv corrosion zoo dua. Nitinol muab superelasticity rau qhov yooj yim heev. Cov khoom siv braid yuav tsum muaj lub zog tensile siab thiab tsis muaj kev sib txhuam; stainless hlau xaim lossis Vectran fibers yog qhov raug. Lub tsho polymer yuav tsum yog biocompatible, nrog ib tug durometer uas haum rau qhov yuav tsum tau yooj yim -PEBAX yog txaus siab rau nws ntau yam hardness. Kev sib cuam tshuam ntawm cov ntaub ntawv no txiav txim siab qhov kev ua tau zoo tag nrho: lub hypotube khoov, braid twists, thiab polymer khi.

Kev faib khoom siv

Cov khoom siv kuaj cov khoom yog qhov tseem ceeb: tensile testers, qaug zog testers, thiab corrosion kuaj chambers raws li ASTM tus qauv. Laser txiav tshuab yuav tsum tau ua kom zoo rau cov khoom siv tshwj xeeb-piv txwv li, qis zog mem tes rau Nitinol kom tsis txhob tawg. Braiding tshuab xav tau nruj tswj tau sib xws nrog cov xov hlau zoo. Polymer extrusion kab yuav tsum muaj qhov kub thiab txias rau cov khoom sib txawv. Cov cuab yeej tshuaj ntsuam saum npoo zoo li SEM thiab EDS pab txheeb xyuas cov khoom muaj pes tsawg leeg thiab kuaj xyuas qhov tsis xws luag.

Phau Ntawv Qhia

Pib nrog kev soj ntsuam kev pheej hmoo. Rau lub coronary guidewire, xaiv 304 SS hypotube rau tus nqi -effectiveness thiab 304 SS braid rau compatibility. Rau cov hlab ntsha neurovascular, xaiv Nitinol hypotube thiab Vectran braid kom txo tau MRI artifacts. Specification Polymer: PEBAX 7233 rau txheej txheej thiab nylon rau txheej txheej los tiv thaiv puas. Laser- txiav nrog cov ntsuas tsis raug lees paub rau txhua yam khoom. Tom qab braiding, ua cov tshuaj tsuag ntsev rau ISO 9227 los ntsuas kev tiv thaiv corrosion. Yog tias corrosion tshwm sim, hloov mus rau 316L lossis siv kev kho mob passivation. Ib txwm txheeb xyuas biocompatibility rau ISO 10993.

Tiag -Kev Paub Txog Ntiaj Teb

Ib European OEM xaiv 17-7PH stainless hlau hypotube rau nws lub zog siab tab sis ntsib tawg thaum lub sij hawm laser txiav. Lawv hloov mus rau 304 thiab daws qhov teeb meem. Lwm lub tuam txhab siv polyethylene braid tab sis pom nws stretched nyob rau hauv load, ua rau poob ntawm torque. Lawv hloov nws nrog ib tug stainless hlau braid thiab ua tiav qhov kev ua tau zoo. Ib lub tuam txhab thib peb tau siv lub tsho PEBAX 6333 tab sis tau ntsib kev muag muag ntawm 37 degree; hloov mus rau qib siab dua durometer daws nws. Cov xwm txheej no qhia tau hais tias kev xaiv cov khoom siv feem ntau yog cov txheej txheem rov qab qhia los ntawm kev sim.

Xaus

Kev xaiv cov khoom siv rau braid reinforced hypotubes yog ib txoj hauv kev sib npaug. Biocompatibility, mechanical zog, thiab manufacturability yuav tsum tau ua raws li tag nrho. Kev sim ua kom zoo thiab txaus siab rau rov hais dua yog qhov tseem ceeb rau kev ua tiav. Kev sib xyaw ntawm cov khoom siv zoo tuaj yeem txhim kho cov cuab yeej ua tau zoo thiab kev nyab xeeb ntawm tus neeg mob.

Outlook & Cov lus qhia

Cov ntaub ntawv tawm tshiab xws li bioresorbable polymers thiab cov duab-memory alloys nrog qhov sib txawv ntawm qhov sib txawv tuaj yeem hloov pauv cov braid reinforced hypotubes. Cov neeg tsim khoom yuav tsum saib xyuas kev tshawb fawb hauv cov cheeb tsam no thiab xav txog kev koom tes nrog cov neeg muab khoom siv. Tsis tas li ntawd, kev ntsuas lub neej ntawm cov ntaub ntawv yuav dhau los ua ib qho tseem ceeb vim tias kev ruaj ntseg nce siab hauv medtech.
