Ultrasonic Tshuaj Polymer Txheej Cov Khoom Siv Stent

Ultrasonic tshuaj polymer stent txheej yog ib txoj kev siv ultrasonic technology los tsim ib tug polymer txheej rau saum npoo ntawm stent thiab embed tshuaj rau hauv nws. Cov txheej no sib xyaw ua ke cov khoom zoo ntawm cov ntaub ntawv polymer thiab cov tshuaj tso tawm los txhim kho kev ua haujlwm ntawm vascular intervention therapy.

Qhov kom zoo dua ntawm ultrasonic tshuaj polymer stent txheej yog tias nws tuaj yeem ua tiav cov tshuaj tso tawm thiab cov txheej txheem ntawm cov txheej txheem polymer. Cov ntaub ntawv polymer muab cov neeg nqa tshuaj uas tuaj yeem tswj hwm tus nqi tso tawm thiab lub sijhawm ntawm cov tshuaj, yog li txhim kho cov txiaj ntsig kev kho mob. Ultrasonic thev naus laus zis tuaj yeem txhim kho qhov adhesion thiab uniformity ntawm coatings, ntxiv kev txhim kho kev ntseeg siab ntawm kev kho mob.

1.Prepare bracket: Xaiv lub bracket tsim nyog thiab xyuas kom meej tias nws nto huv si thiab tsis muaj impurities.

2.Kev npaj cov tshuaj polymer: xaiv cov khoom siv polymer uas tsim nyog thiab yaj lawv hauv cov kuab tshuaj tsim nyog los tsim cov tshuaj polymer. Kev xaiv cov polymers yuav tsum xav txog yam xws li lawv cov biocompatibility, adhesion, thiab cov tshuaj muaj peev xwm thauj khoom.

3.Polymer txheej tsim: Muab lub scaffold rau hauv cov tshuaj polymer kom ntub nws saum npoo. Tom qab ntawd, cov txheej txheem ultrasonic xws li ultrasonic txau lossis ultrasonic kev co yog siv los txhawb kev tsim cov txheej txheej ntawm cov polymer ntawm qhov chaw ntawm lub scaffold. Lub zog ntawm ultrasound tuaj yeem txhim kho qhov adhesion thiab uniformity ntawm txheej.

4.Drug embedding: Embedding cov tshuaj xav tau rau hauv lub polymer matrix thaum tsim cov txheej txheem polymer. Cov tshuaj tuaj yeem yog cov tshuaj molecules yaj hauv cov tshuaj polymer, nrog rau cov khoom siv tshuaj los yog nanoparticles.

5.Drying thiab Curing: Tom qab ua tiav cov txheej txheem thiab cov tshuaj txhaj tshuaj, lub scaffold yuav tsum tau qhuav thiab kho kom zoo dua qub thiab adhesion ntawm txheej.
