Kev xaiv cov khoom cuam tshuam li cas rau cov khoom siv Lifespan?

Kev xaiv cov khoom siv rau kev kho mob cov khoom siv kho mob ncaj qha txiav txim siab txog cov khoom siv lub neej, kev nyab xeeb, thiab kev siv cov khoom siv. Cov ntaub ntawv tsis tsim nyog tuaj yeem ua rau kev laus, corrosion, lossis hnav, ua rau cov cuab yeej ua tsis tiav ntxov thiab muaj kev nyab xeeb.

1. Cov khoom siv hlau: Lub hauv paus ntawm Durability, txiav txim siab ntev -Lub sij hawm ruaj khov

• Titanium Alloy: Vim nws zoo heev corrosion kuj thiab biocompatibility, nws yuav siv tau rau 15-25 xyoo los yog ntev dua nyob rau hauv implantable pab kiag li lawm (xws li cranioplasty daim hlau thiab dag pob qij txha). Qhov ntom ntom oxide zaj duab xis tsim rau ntawm nws qhov chaw tiv thaiv corrosion los ntawm lub cev ua kua thiab rov ua kom tsis muaj menyuam, ua kom nws txoj sia ntev.
• Stainless Hlau: Txawm hais tias muaj zog, nws yog qhov yooj yim rau pitting thiab xeb thaum raug tshuaj tua kab mob lossis cov kua dej hauv lub cev rau lub sijhawm ntev, ua rau kev ua haujlwm tsis zoo. Nws qhov nruab nrab lifespan yog li 3-5 xyoos, luv luv tshaj li titanium alloys.
• Aluminium Alloy: Muaj qhov zoo ntawm qhov hnyav, tab sis yuav tsum muaj anodizing los txhim kho corrosion; txwv tsis pub, nws yog nquag oxidation thiab tev tawm hauv kev tu thiab tshuaj tua kab mob ntau zaus, cuam tshuam rau kev ncaj ncees ntawm cov qauv.

2. Cov Khoom Siv Polymer: Kev ua tau zoo sib txawv, kev xaiv cov khoom cuam tshuam rau lub neej

• PEEK (Polyetheretherketone): Kub kub tsis kam (txog 260 degree), muaj zog qaug zog tsis kam, haum rau cov khoom siv neurosurgical uas yuav tsum tau rov ua kom tsis muaj qhov kub thiab txias, nrog lub neej ntev tshaj 15 xyoo, thiab tsis muaj cov khoom siv hlau, muaj txiaj ntsig zoo rau kev saib xyuas cov duab.
• Kev Kho Mob Silicone thiab Roj Hmab: Cov mos mos thiab xis nyob, tab sis nws yooj yim rau kev laus thiab tawg nyob rau hauv ntev -kev ntxhov siab, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig ultraviolet lossis ozone. Lifespan feem ntau yog 3-8 xyoo, yuav tsum tau hloov lub sij hawm.
• ABS / PVC Engineering Plastics: Tus nqi qis, ua haujlwm yooj yim, tab sis tsis muaj zog tiv thaiv thiab tshuaj lom neeg; ntev - siv sij hawm yuav ua rau embrittlement thiab discoloration. Haum rau luv luv - lub sij hawm los yog qis - khoom siv thauj khoom.

3. Cov ntaub ntawv sib xyaw: Lub teeb yuag thiab siab -Lub zog, txuas cov khoom siv tag nrho lub neej

• Carbon Fiber Reinforced Materials: Tsuas yog ib nrab ntawm qhov ntom ntom ntawm aluminium alloy, tsis tau peb zaug muaj zog dua, thiab corrosion-tiv taus thiab qaug zog-tiv taus, dav siv hauv lub rooj zaum log, exoskeleton robots, thiab lwm yam khoom siv txawb. Nws "tsawg ceev + lub zog siab" cov yam ntxwv ua rau txo qis kev hnav thiab ua kom ntev tag nrho lub neej. Nws kuj muaj X-ray permeability, ua kom yooj yim saib xyuas tom qab phais.
• Cov pa roj carbon fiber ntau / PEEK cov khoom sib xyaw: Kev sib xyaw kom zoo ntawm ob qho tib si, nws yog siv rau hauv siab - zaus txav qhov chaw (xws li cov pob qij txha hauv kev kho neeg hlau), ua kom pom kev qaug zog zoo heev thiab muaj peev xwm tiv taus ntau lab lub voj voog ntawm kev thauj khoom, txo qhov ua tsis tiav.
