Daim ntawv thov ntawm 3D luam tawm titanium alloy hauv kev phais mob yog qhov tsim nyog rau kev kho pob txha thiab kho thiab txhim kho kev mob.
Daim ntawv thov kev phais pob qij txha Artificial joint hloov yog ib txoj hauv kev zoo los kho cov kab mob sib koom ua ke. Kev sib koom ua ke tuaj yeem txhim kho cov tsos mob thiab rov ua haujlwm. Titanium alloy muaj qhov zoo compression tsis kam thiab siab hnav tsis kam, thiab tsim nyog rau kev npaj cov pob qij txha orthopedic. Nyob rau hauv xyoo tas los no, kev sib xyaw ntawm titanium alloy thiab 3D luam ntawv thev naus laus zis tau nyiam ntau thiab ntau dua rau kev npaj ntawm cov cog cog uas haum rau kev sib koom ua ke. Ding Yujian et al. qhia ib rooj plaub ntawm kev kho dua tshiab hauv 2019. Tus neeg mob tau txais kev txo qis thiab kev kho sab hauv ob zaug rau "sab laug femoral caj dab tawg". Nws tau hloov lub duav hauv xyoo 2006 thiab kho dua xyoo 2019. Tus neeg mob lub cev thiab keeb kwm ntawm ntau yam kev ua haujlwm ua rau kev ua haujlwm nyuaj thiab pheej hmoo. Txhawm rau txhim kho qhov ua tau zoo ntawm kev ua haujlwm, pab pawg phais tau txais cov ntaub ntawv duab thiab rov tsim kho nws siv 3D luam ntawv thev naus laus zis los luam tawm tus qauv zoo ib yam nrog tus neeg mob lub plab thiab cov qauv 3D luam tawm los hloov. Lub titanium alloy prosthesis tau raug rehearsed los xyuas kom meej qhov kev vam meej ntawm kev ua haujlwm. Li Juehong et al. siv 3D luam titanium alloy pads los kho cov pob txha acetabular complex. Tsis muaj loosening ntawm prosthesis tau pom nyob rau hauv postoperative rov qab, thiab curative nyhuv yog txhim khu kev qha. Qhov taw qhia tseem ceeb los ntsuas qhov ua tiav ntawm kev sib koom ua ke hloov pauv yog qhov mob thiab lwm yam tsos mob zoo dua tom qab ua haujlwm, thiab lub neej zoo dua qub. Daim ntawv thov ntawm 3D luam ntawv thev naus laus zis ua ke nrog titanium alloy los npaj cov cog cog tsis tsuas yog muaj cov yam ntxwv zoo ntawm titanium alloys, tab sis kuj yog cov cog cog tau sib haum nrog kev sib koom ua ke ntawm cov neeg mob. Nws muaj kev sib raug zoo, txo cov teeb meem xws li kev sib koom ua ke thiab tsim kua muag, thiab txhim kho lub neej zoo ntawm cov neeg mob. Wan et al. faib 42 tus neeg mob uas xav tau kev kho acetabular ua ob pawg, ib pab pawg tau siv 3D luam tawm cov ntaub ntawv titanium alloy porous, ua raws li 3 lub hlis, 6 hli, thiab 9 lub hlis tom qab kev phais, thiab pom tias pawg soj ntsuam tau ua raws li kev sib piv nrog pawg tswj hwm, SF-36 tau qhab nia siab dua, thiab VAS cov qhab nia qis dua, qhia tias pawg 3D luam ntawv tau txais txiaj ntsig zoo dua. Zhang et al. thov 3D luam ntawv titanium alloy los kho cov pob txha trabecular los kho osteonecrosis thaum ntxov ntawm lub taub hau femoral. Txhawm rau ntsuas qhov kev ua haujlwm ntawm lub duav sib koom ua ke, cov qhab nia tom qab Harris thiab qhov mob pom qhov muag analog (VAS) tau siv. Thaum lub sijhawm 24-hloov rov qab, cov qhab nia tom qab Harris tau nce ntau thiab VAS cov qhab nia poob qis ntawm 12 lub hlis tom qab ua haujlwm. Nrog rau qhov hnyav ntawm femoral taub hau necrosis, Harris qhab nia qis me ntsis thiab VAS tau nce me ntsis. Postoperative txhim kho tus nqi yog 100 feem pua rau ARCO IIA theem, 70 feem pua rau IIB theem thiab 0 feem pua rau IIC theem. Kev khaws cia ntawm lub duav yog 100 feem pua rau theem IIA, 100 feem pua rau theem IIB, thiab 50 feem pua rau theem IIC. Cov txiaj ntsig tau pom tias 3D luam ntawv titanium alloy txoj kev kho mob muaj txiaj ntsig zoo rau cov necrosis thaum ntxov ntawm lub taub hau femoral, thiab cov tsos mob kho tau zoo.
Daim ntawv thov kev phais pob txha pob txha pob txha phais feem ntau yuav tsum tau npaj cov prostheses los hloov ib feem ntawm cov ceg. Daim ntawv thov ntawm 3D luam titanium alloys muaj kev ruaj ntseg thiab zoo plasticity, thiab yog haum rau cog kev npaj. Cov teeb meem tom qab phais tsawg dua yog qhov tsim nyog rau kev kho cov pob txha tom qab. Xyoo 2020, Lin Yunzhi et al. tshaj tawm ib rooj plaub ntawm cov qog loj heev ntawm cov pob txha uas siv 3D tshuab luam ntawv ua ntej thiab thaum lub sijhawm ua haujlwm. Cov ntaub ntawv duab tau sau ua ntej ua haujlwm, thiab 3D luam ntawv qauv tau tsim rau kev soj ntsuam zoo. 3D luam ntawv implants nrog cov txiaj ntsig zoo. Los ntawm 2017 txog 2019, Lei Qing li al. siv 3D luam ntawv qhia phaj ua ke nrog 3D luam ntawv titanium alloy trabecular pob txha los kho 2 tus neeg mob ntawm cov qog nqaij hlav humeral. Kev ua raws li tau ua tom qab ua haujlwm. Ntawm lawv, 1 rooj plaub muaj kev soj ntsuam zoo, thiab lwm rooj plaub muaj kev soj ntsuam zoo tom qab ua haujlwm. Lub prosthesis loosened ntawm 14 lub hlis thiab tau txhawb nqa los ntawm kev phais dua. Kev ua raws li 34 lub hlis tom qab kev ua haujlwm pom tias tsis muaj kev hloov pauv ntawm cov prosthesis. Wang et al. siv 3D luam ntawv thev naus laus zis los luam prostheses thiab siv rau 11 tus neeg mob qog nqaij hlav hauv plab. Cov nyhuv postoperative tau zoo thiab tsis pom kev xoob xoob. Nyob rau hauv 2019, Feng tau tshaj tawm ib rooj plaub ntawm radical resection ntawm tibial fibroblastoma thiab siv 3D luam titanium alloy los cawm tus ceg. Cov prosthesis tau ua raws li 1 xyoos thiab tsis pom qhov xoob ntawm cov prosthesis. Raws li MSTS cov qhab nia, qhov kev ua haujlwm rov qab yog 86.7 feem pua. Muaj kev sib koom ua ke zoo ntawm lub cev thiab tus neeg mob cov pob txha. Daim ntawv thov ntawm 3D luam titanium alloy implants nyob rau hauv cov pob txha qog nqaij hlav tuaj yeem tau txais kev tsim kho anatomical ntau dua, ua kom cov neeg mob rov zoo dua, thiab ua tiav cov txiaj ntsig kev phais zoo dua.
Kev txhim kho ntawm 3D luam ntawv titanium alloy
Titanium alloy ua ke nrog 3D tshuab luam ntawv tuaj yeem simulate cov pob txha autologous mus rau qhov loj tshaj plaws, thiab nws cov microscopic pore loj, porosity, thiab pore zoo tag nrho yuav cuam tshuam rau biocompatibility ntawm cov khoom. Cov ntaub ntawv uas twb muaj lawm qhia tau hais tias cov kev tshawb fawb xaus rau qhov pom qhov pore loj ntawm 3D luam titanium alloys tsis zoo ib yam. Kev tshawb fawb los ntawm Peng et al. tau pom tias qhov porosity ntawm 3D luam titanium alloys nyob nruab nrab ntawm 60.95 feem pua thiab 81.23 feem pua, thiab qhov pore loj yog nyob nruab nrab ntawm 480 thiab 685 μm, uas yog haum rau orthopedic implants. Nyob nruab nrab ntawm 265μm, Young's modulus yog nruab nrab ntawm 2.23-6.36Gpa, yield zog yog 21.36-122.85Mpa, thiab muaj zoo elastic modulus thiab lub zog.
