Kev ua haujlwm niaj hnub ntawm cov khoom siv tes ua tau tsim kho sai, uas tso cai rau kev txhim kho kev ua neej nyob ntawm cov neeg uas, vim qee yam, tau poob qis.
Hnub no, ob txhais ceg prosthetic tau dhau los ua cov cuab yeej siv siab. Biomechatronics tau dhau los ua qhov tseem ceeb hauv kev ua haujlwm prosthetics. Nrog nws cov kev pab, bioelectric prostheses ntawm ib tiam tshiab tau pib ua. Lawv sau npe hluav taws xob teeb liab thaum lub sij hawm contraction ntawm cov leeg ntawm cov leeg leeg raug mob, uas tso cai rau ntau yam kev txav. Nyob rau tib lub sijhawm, lawv cov haujlwm tseem tuaj yeem tshaj qhov ua tau zoo ntawm ob txhais ceg.
Qee tus ntawm lawv tuaj yeem tsim kho rau tus kheej txav. Tsis tas li ntawd, cov ceg pob qij txha tuaj yeem muaj cov txheej txheem silicone tshwj xeeb uas npog qhov tsis xws luag, uas pab txhawm rau txhawm rau txhawm rau tsis muaj ceg tawv thiab txo qis tsis xav tau ntawm lwm tus.
Qhov kev ua tiav tshiab tshaj plaws hauv kev ua haujlwm ntawm cov pob qij txha yog osseointegration (kev cog qoob loo ntawm prosthesis rau hauv pob txha). Cov txheej txheem no tso cai rau kom txo tau qhov rubbing lossis raug mob rau cov pob txha, nrog rau kev tswj xyuas tag nrho cov ceg tawv. Xws li cov ceg prostheses ntawm cov ntsiab lus ntawm kev tawm ntawm cov pob txha cov ntaub so ntswg yog them nrog tshwj xeebib yam khoom uas tsis yog tsuas yog ua raws li cov ntaub so ntswg, tab sis kuj zoo kawg nkaus tiv thaiv ntau yam kab mob.
Cov neeg nyiam tshaj plaws qis qis prostheses yog cov qauv nrog lub tshuab hluav taws xob. Lawv tau tsav hydraulically, suav nrog microprocessor thiab software tshwj xeeb.
Cov ceg pob txha no tau tsim tawm txij li xyoo 1997, tab sis twb dhau los ua classics. Lawv ua haujlwm ntau dua li cov qauv siv tshuab, muaj peb hom kev ua haujlwm, nrog rau cov chaw taws teeb tswj. Qhov no tso cai rau tus neeg tsis nco qab txog qhov kev tsim ntawm nws txhais ceg, vim nws tso cai tsis tau tsuas yog taug kev, tab sis kuj nce ntaiv lossis caij tsheb kauj vab.
Hauv xyoo 2006, ib qho khoom siv hluav taws xob nrog kev txawj ntse tsim tau. Ua tsaug rau kev ua haujlwm zoo ntawm cov sensors thiab microprocessors, nws yuav siv sij hawm rau hauv tus account tus yam ntxwv ntawm ib tug neeg lub gait, thiab kuj tswj cov theem ntawm cov kua nyob rau hauv cov khoom sib koom tes, uas tso cai rau koj kom tau txais kev nplij siab ntxiv thaum tsiv lub cev.
Nws tsim nyog sau cia tias qhov teeb meem tseem ceeb hauv kev txhim kho cov ceg tawv yog tsim kom muaj kev pom zoo rau kev ua haujlwm tag nrho ntawm ko taw. Niaj hnub nimno ceg prostheses yog tsim los nrog cov yam ntxwv no hauv siab. Yog li, lawv tau nruab nrog cov tshuab hydraulic uas ua kom zoo li qhov chaw ntawm ko taw thaum taug kev, sawv lossis khiav.
Kuv yuav tsum hais tias cov khoom siv zoo nkauj yog qhov tsim nyog rau kev kho kom zoo ntawm lub cev muaj zog thiab kev txhawb nqaploj limb. Leg prostheses, tus nqi ntawm qhov sib txawv, zam ntau yam teeb meem, nrog rau kev pab kom muaj kev sib npaug. Tsis tas li ntawd, cov caj npab niaj hnub ua rau nws tuaj yeem tsis tsuas yog taug kev, tab sis kuj tseem khiav, nce, nthwv dej, caij ski lossis skate, yog li nws tuaj yeem sib cav tias tsuas muaj cov cuab yeej siv dag zog zoo xwb, thiab tsis yog cov neeg xiam oob qhab.
