Nrog rau kev txhim kho ntawm kev lag luam orthopedic, kev tshawb fawb txog cov khoom siv cog hniav kuj tseem nyiam cov neeg lub siab ntxiv. Raws li Yao Zhixiu cov lus qhia, tam sim nocog rau hauv lub qhovCov khoom siv hlau feem ntau suav nrog stainless hlau, titanium thiab titanium alloy, cobalt base alloy thiab cov khoom siv no yuav muaj nyob ntev. Rau Titanium thiab titanium alloy, cov chaw tsim khoom siv twj paj nruag hauv zos feem ntau siv cov titanium ntshiab thiab Ti6Al4V alloy (TC4), thaum Asmeskas muaj 12 hom titanium alloy cov khoom siv rau kev cog hniav thiab feem ntau hauv Tebchaws Europe thiab Asmeskas yog Ti6Al4VELI thiab Ti6Al7Nb.
Wu Xiaolei, Tus Thawj Saib Xyuas Kev Muag Khoom Asia-Pacific ntawm Sandvik Medical Technology tau hais tias, cov khoom siv hlau tsis xeb yog siv dav hauv Tebchaws Europe thiab Tebchaws Meskas, thiab kev lag luam hauv Suav teb yog qhov nyuaj heev: cov khoom sib txawv yog qhov tsim nyog rau ntau yam kev lag luam tab sis feem ntau lawv nyiam titanium thiab titanium alloy. "Los ntawm qhov taw tes ntawmpob qij txhaCov ntawv thov, cov ntaub ntawv sib txawv raug xaiv los ntawm ntau lub hom phiaj sib txawv, piv txwv li, tuav lub zog yuav tsum xaiv cov khoom siv hlau tsis muaj nitrogen siab uas muaj zog dua; thaum xav tau cov ntaub ntawv hnav tsis kam, peb tuaj yeem xaiv Cobalt chromium molybdenum alloy.
Tam sim no, kev hloov kho qhov chaw yog ib qho tseem ceeb ntawm kev txhim kho cov khoom siv orthopedic implant. "Qhov chaw ntawm cov khoom siv implanted ncaj qha kov nrog lub cev tib neeg thiab los ntawm kev hloov kho qhov chaw, nws tuaj yeem txhim kho kev sib raug zoo ntawm lub cev thiab txo qhov hnav thiab tsim kua muag, thiab yog li nws tuaj yeem txo qhov xoob ntawm implant thiab xyuas kom meej tias muaj kev ua tau zoo mus sij hawm ntev." Wu Xiaolei tau hais tias, piv txwv li, Sandvik Bioline 316LVM siv rau kev cog rau tib neeg thiab Bioline 1RK91 rau kev tsim cov khoom siv kho mob. Tus qub yog lub tshuab nqus tsev re yaj molybdenum austenitic stainless hlau nrog kev huv huv zoo thiab kev tiv thaiv corrosion, thiab nws tuaj yeem siv rau cov tes sib koom ua ke, lub taub hau femoral, cov phaj pob txha, cov rau tes pob txha, cov koob txhaj tshuaj pob txha,cov rau tes hauv qab, khob acetabular; qhov kawg yog ib hom hlau tsis xeb uas ua kom tawv, uas feem ntau siv rau hauv cov cuab yeej phais xws licov pob txha xyaumthiab cov koob txhaj pob txha, thiab nws qhia tau tias muaj zog dua, tawv thiab tiv taus corrosion. Ob leeg muaj daim ntawv thov dav dua hauv kev lag luam hauv Suav teb.
"Peb kuj tuaj yeem kawm tau kev paub los ntawm lwm qhov chaw, piv txwv li, siv cov khoom siv cuab yeej los tsim cov khoom siv raukev cog pob qij txhakev tsim cov khoom siv thiab siv cov txheej txheem ceramic kom ua tiav kev hloov kho qhov chaw.
