PLA Cov Khoom Siv Kho Mob

PLA tau siv dav hauv suture, pob txha kho, kho cov ntaub ntawv, cov cab kuj rau qeeb thiab tswj kev tso tawm ntawm cov tshuaj, cov ntaub so ntswg engineering cell loj hlob scaffold cov ntaub ntawv thiab lwm yam teb, thiab tau dhau los ua ib qho ntawm cov khoom tseem ceeb hauv kev kho mob. PLA suture tuaj yeem ua tau raws li qhov xav tau ntawm suture hauv lub zog, thiab maj mam decompose thiab ploj hauv lub cev thaum lub qhov txhab kho. Piv nrog cov pa suture, tsis tas yuav tshem tawm suture, thiab nws yog qhov tshwj xeeb tshaj yog tsim rau suture ntawm cov ntaub so ntswg sib sib zog nqus.

PLA tuaj yeem siv los ua cov khoom siv pob txha. Nrog rau kev loj hlob ntawm cov pob txha, cov pob txha kho cov khoom tsim los ntawm PLA tuaj yeem decomposed maj mam, tsis tas yuav tsum tau ua haujlwm thib ob kom tshem tawm nws, kom tsis txhob muaj qhov mob ntawm lub cev thiab cov nqi phais uas tshwm sim los ntawm kev ua haujlwm thib ob. PLA tuaj yeem siv los ua tus cab kuj rau qeeb thiab tswj kev tso tawm cov tshuaj, uas muaj qhov zoo ntawm cov tshuaj lom neeg tsawg, kev ua haujlwm siab, kev tso tawm qeeb thiab lub sijhawm ua haujlwm ntev, kev sib raug zoo nrog cov kab mob, lub sijhawm nyob ntev, thiab tseem tuaj yeem siv txoj hauv kev copolymerization nrog lwm cov monomers los tswj cov kev tso tawm ntawm cov tshuaj, txhawm rau txhim kho kev ua haujlwm ntawm cov tshuaj thiab txo cov tshuaj lom neeg lub cev.

PLA tuaj yeem siv los ua cov ntaub so ntswg engineering scaffold khoom. Los ntawm kab lis kev cai ntawm PLA scaffold, cov hlwb maj mam loj hlob thiab sib txawv rau hauv cov ntaub so ntswg thiab cov kabmob. Tib lub sijhawm, PLA scaffold cov khoom maj mam degrades.

PLA, raws li hom tshiab ntawm cov ntshiab bio-raws li cov ntaub ntawv, muaj kev lag luam zoo rau kev thov. Nws lub cev zoo thiab kev tiv thaiv ib puag ncig ntawm cov khoom nws tus kheej yuav twv yuav raug hu ua PLA siv ntau dua yav tom ntej.

Txawm li cas los xij, thaum PLA cov ntaub ntawv siv rau cov khoom ntim, tseem muaj ntau yam khoom uas yuav tsum tau txhim kho ntxiv, xws li degradability, toughness, tshav kub tsis kam, barrier, hluav taws xob conductivity, thiab lwm yam. Tsis tas li ntawd, tam sim no tus nqi raw khoom siab kuj yog ib qho tseem ceeb txwv tsis pub siv cov khoom siv PLA. Nws yog ib qho tsim nyog los txhim kho PLA cov txheej txheem ntau lawm, txo cov nqi khoom thiab txhim kho nws cov kev sib tw ua cov khoom ntim.
