Ureteroscope Clamps Ua Los ntawm Titanium Alloy Poob-Wax Casting

o Feem ntau siv titanium alloys rau ureteroscopic clips suav nrog Ti-6Al-4V. Aluminium (Al) txhim khu lub zog thiab thermal stability ntawm titanium alloys, tswj cov khoom siv kho kom zoo nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias. Vanadium (V) txhim kho machinability, yooj yim casting.

o Lwm cov ntsiab lus, xws li hlau (Fe) thiab oxygen (O), tuaj yeem muab ntxiv rau me me kom tau raws li cov kev xav tau tshwj xeeb. Cov nyiaj tsim nyog ntawm cov hlau ntxiv ua kom muaj zog hlau ntxiv, thaum qee cov pa oxygen txhim kho hardness; Txawm li cas los xij, cov nyiaj ntxiv yuav tsum nruj me ntsis tswj kom tsis txhob muaj kev cuam tshuam toughness thiab biocompatibility.

o Lub purity ntawm raw khoom yog qhov tseem ceeb. Cov ntsiab lus impurity nyob rau hauv titanium alloy raw cov ntaub ntawv yuav tsum tau nruj me ntsis tswj. Heavy hlau impurities xws li txhuas (Pb) thiab mercury (Hg) yuav tsum tau khaws cia nyob rau theem qis heev kom ntseeg tau tias biocompatibility.

o Kev tshuaj xyuas nruj me ntsis ntawm cov khoom siv titanium alloy raw khoom yog qhov tseem ceeb, suav nrog tshuaj lom neeg kev tshuaj ntsuam xyuas thiab kuaj cov cuab yeej cuab yeej. Kev tshuaj xyuas tshuaj muaj pes tsawg leeg tuaj yeem siv txoj hauv kev xws li kev tshuaj xyuas spectral los xyuas kom meej tias cov ntsiab lus ntawm txhua lub caij ua tau raws li cov qauv tsim. Kev ntsuam xyuas cov cuab yeej cuab tam, xws li kev xeem tensile thiab hardness test, xyuas kom meej tias cov khoom muaj lub zog tsim nyog, toughness, thiab hardness.

o Tsim thiab Qauv: Ua ntej, raws li cov qauv tsim ntawm lub ureteroscope clamp, 3D qauv yog tsim los ntawm kev siv computer-aided design (CAD) software. Xav txog qhov yuav tsum tau ua ntawm lub clamp, xws li clamping quab yuam thiab qhib lub kaum sab xis, cov duab, qhov loj me, thiab cov qauv ntawm cov clamp yog tsim los. Piv txwv li, lub taub hau clamp yuav tsum tau tsim nrog cov duab tsim nyog los xyuas kom meej qhov kev tuav ntawm cov ntaub so ntswg lossis cov khoom txawv teb chaws, thaum ua kom muaj kev sib faib ntawm cov clamping quab yuam.

o Wax Model Forming: Siv precision txhaj molding, siv quav ciab yog txhaj rau hauv pwm los tsim cov qauv siv quav ciab zoo ib yam rau cov ureteroscope clamp. Xaiv ib qho kev siv quav ciab yog qhov tseem ceeb heev; cov ciab yuav tsum muaj zoo flowability thiab formability kom raug replicate cov ntsiab lus ntawm pwm. Thaum lub sij hawm txhaj tshuaj molding, tsis xws li kub, siab, thiab kev txhaj tshuaj ceev yuav tsum tau ua tib zoo tswj kom tsis txhob muaj qhov tsis xws luag xws li npuas thiab tawg hauv cov qauv siv quav ciab.

o Wax Model Assembly: Ib tus qauv siv quav ciab txuas nrog wax rods los tsim cov qauv siv quav ciab rau kev ua haujlwm tom ntej.
