Kev Xaiv Cov Khoom Siv Logic: Cov Txheej Txheem Rau Kev Sib Raug Zoo Ntawm Cov Hlau Thiab Cov Khoom Siv Polymer Rau Cov Khaub Ncaws Cuam Tshuam Pov Tseg.

Kev xaiv cov khoom siv logic: Cov txheej txheem rau kev sib raug zoo ntawm cov hlau thiab cov ntaub ntawv polymer rau cov koob catheter pov tseg. Cov koob catheter pov tseg, raws li cov cuab yeej tseem ceeb thoob plaws tag nrho cov txheej txheem ntawm kev phais me me, lawv cov khoom xaiv ncaj qha txiav txim siab cov khoom siv, biocompatibility, kev nyab xeeb ntawm kev siv, thiab kev xav ntawm cov khoom. Qhov no yog ib qho tseem ceeb ntawm kev tsim khoom thiab kev tsim khoom hauv kev lag luam. Kev lag luam ua raws li lub hauv paus ntsiab lus ntawm "cov khoom sib faib thiab cov khoom siv sib xws", sib txawv ntawm cov khoom siv hlau thiab yas kom ua tiav qhov kev sib npaug ntawm kev ua tau zoo thiab tus nqi. Cov khoom siv hlau feem ntau muaj cov qauv catheter thiab yog cov tub ntxhais thauj khoom -cov kabmob thiab cov kab nqa khoom ntawm cov koob catheter pov tseg. Cov khoom xaiv tsom rau peb hom khoom: kev kho mob stainless hlau, cobalt-chromium alloy, thiab nickel-titanium alloy. Txhua hom khoom muaj nws qhov kev ua tau zoo tshwj xeeb thiab tsim nyog rau qhov kev xav tau kev phais sib txawv. 304 kev kho mob stainless hlau yog cov khoom siv yooj yim xaiv, muaj cov khoom siv zoo heev, kev tiv thaiv corrosion, thiab kev ua haujlwm, nrog rau kev ua haujlwm tawv tawv ntawm HRC22-25, muab tus nqi siab- ua tau zoo thiab tsim nyog rau kev xaiv laparoscopic niaj hnub; 316L kev kho mob stainless hlau yog cov khoom siv kho dua tshiab, txhim kho corrosion kuj thiab tiv thaiv{15}}bioadhesion kev ua tau zoo raws li 304 stainless hlau, nrog rau biocompatibility zoo dua, txo cov ntaub so ntswg ua xua thiab kis kab mob, tsim nyog rau kev kho kom zoo thiab ntev - ncua sij hawm cuam tshuam tsawg kawg nkaus. L605 cobalt-chromium alloy yog qhov siab - xaiv cov khoom siv kawg, nrog rau qhov hardness ntau ntawm HRC20-40, featuring ultra-siab zog, hnav tsis kam, thiab corrosion kuj, thiab rab koob lub cev yog tsis tshua muaj kev deformation thiab hnav, haum rau complex thiab nyuaj minimally invasives invasives thiab invasives. tshem tawm kev sib txhuam losses; Nickel-titanium alloy, nrog nws cov elasticity super thiab cov duab nco, tuaj yeem hloov kho rau cov ntaub so ntswg nkhaus, ua kom cov ntaub so ntswg tsis zoo thaum lub sij hawm puncture thiab txo cov ntaub so ntswg puas tsuaj, haum rau tshwj xeeb minimally invasive intervention surgeries. Cov khoom siv yas muaj xws li kaw- cov khoom siv lub qhov, cov khoom sib khi, thiab cov qauv valve, thiab cov kev xaiv tseem ceeb ntawm cov khoom no yog tsim los ntawm plaub hom kev kho mob siab -cov ntaub ntawv polymer: ABS resin, silicone, nylon, thiab polycarbonate (PC). Txhua hom muaj kev ua haujlwm tshwj xeeb. ABS resin muaj qhov zoo molding thiab cov qauv muaj zog thiab feem ntau yog siv los ua cov khoom siv dag zog xws li cov leeg thiab cov hauv paus, muab kev xav zoo thiab ruaj khov; Cov khoom siv silicone muaj qhov ua tau zoo thiab kev sib khi zoo thiab yog cov khoom siv zoo tshaj plaws rau cov khoom sib khi, tiv thaiv cov pa tawm thiab muaj biocompatibility zoo heev, tsis ua rau tib neeg cov ntaub so ntswg; Cov khoom siv nylon muaj qhov hnav tsis kam thiab tawv, haum rau lub valve, latch, thiab lwm yam khoom siv txav tau, kom ntseeg tau tias qhib thiab kaw thiab kav ntev; Polycarbonate (PC) muaj qhov pom kev pom tseeb thiab lub zog muaj zog, feem ntau yog siv rau cov lus qhia puncture, kev soj ntsuam qhov rais, thiab lwm yam, tsis muaj shrinkage, npuas, los yog impurities, yooj yim rau cov kws kho mob kom meej meej soj ntsuam cov puncture txheej thiab txhim kho puncture raug. Kev xaiv cov khoom siv tsis yog tsuas yog yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua tab sis kuj yuav tsum ua raws li cov qauv kev nyab xeeb ntawm cov khoom siv kho mob. Tag nrho cov ntaub ntawv hlau yuav tsum ncav cuag kev kho mob-qib purity, tsis muaj kev pheej hmoo ntawm hnyav hlau leaching, thiab tom qab electrolytic polishing, nto yog ci, flawless, tsis muaj khawb, los yog impurities; Cov ntaub ntawv yas yog txhua qib kev kho mob tsis muaj menyuam, ua tau raws li cov qauv kev nyab xeeb rau tib neeg kev sib cuag, tsis muaj tshuaj lom lossis ua xua. Nyob rau tib lub sijhawm, cov khoom siv sib xws kuj yuav tsum xav txog cov txheej txheem ua haujlwm. Cov ntaub ntawv hlau yuav tsum tau sib xws nrog precision tig, vuam, thiab ncab cov txheej txheem, thaum cov ntaub ntawv yas yuav tsum tau ua kom tau raws li kev txhaj tshuaj molding los xyuas kom meej qhov kev ua haujlwm raug thiab kev ncaj ncees ntawm cov khoom. Kev xaiv cov ntaub ntawv tshawb fawb tso cai rau cov koob catheter pov tseg kom ua tiav cov hom phiaj kev ua haujlwm ntawm "cov khoom siv hlau muaj zog thiab ruaj khov thiab muaj kev nyab xeeb thiab siv tau cov khoom siv yas", ua kom muaj kev ua haujlwm ntawm kev sib tsoo thiab kev tsim channel, thaum tshem tawm cov kev pheej hmoo kho mob los ntawm cov ntaub ntawv lawv tus kheej. Nws yog qhov yuav tsum tau ua ua ntej rau kev nyab xeeb kev siv cov koob catheter pov tseg thiab tseem muab cov qauv siv rau kev xaiv cov khoom siv kho mob zoo sib xws hauv kev lag luam.
