siab purity tungsten hlau tungsten guidewire scalpel rau kev kho mob
Ib txoj hlua hauv cov khoom siv kho mob yog ib txoj hlua nyias, hloov tau yooj yim siv los coj thiab tso cov khoom siv kho mob, xws li catheters, hauv lub cev thaum muaj ntau yam txheej txheem kho mob. Guidewires feem ntau yog siv nyob rau hauv minimally invasive thiab interventional txheej txheem kom dhau los ntawm cov hlab ntsha, hlab ntsha, thiab lwm yam anatomical lug. Lawv tau tsim los ua maneuverable thiab muab kev txhawb nqa rau kev tso kawm ntawm cov cuab yeej kho mob, kom ntseeg tau meej thiab tswj kev taw qhia hauv lub cev. Guidewires ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv kho mob, suav nrog kev mob plawv, hluav taws xob, thiab kev phais mob endovascular.
Tungsten yog siv rau hauv ntau daim ntawv thov vim nws cov khoom zoo heev. Nws yog dav siv vim nws qhov siab melting point, zoo thermal conductivity, corrosion kuj thiab oxidation kuj. Cov khoom no ua rau tungsten tshwj xeeb tshaj yog muaj txiaj ntsig nyob rau hauv qhov kub thiab txias xws li cov khoom cua sov, kev sib cuag hluav taws xob thiab cov khoom siv hluav taws xob. Tsis tas li ntawd, nws lub zog, qhov ntom ntom thiab biocompatibility ua rau nws tsim nyog siv rau hauv cov khoom siv kho mob xws li kev qhia xov hlau thiab cov cuab yeej phais. Kev sib xyaw ua ke ntawm cov khoom no ua rau tungsten muaj ntau yam khoom siv thiab muaj txiaj ntsig uas tuaj yeem siv rau hauv ntau hom kev lag luam, kev lag luam thiab kev siv kho mob.
Yog, tungsten yog insoluble hauv dej, uas txhais tau hais tias nws yuav tsis hnov mob lossis yaj hauv dej. Cov cuab yeej no ua rau tungsten tsim nyog siv rau hauv cov ntawv thov uas raug dej lossis lwm yam kua dej yog qhov xav tau, xws li hauv qee qhov kev lag luam thiab kev tsim khoom.
