Niki PDLLA Poly (DL-lactide) CAS 51056-13-9?

PDLLA ni polymer amorphous ifite ubushyuhe bwikirahure bwa 50-60 ℃ hamwe nuburinganire bwa 0.2-7.0dl / g. Ibikoresho byemejwe na FDA kandi birashobora gukoreshwa nkibisubizo byubuvuzi bwo kubaga imiti igabanya ubukana bwa mikorobe, microcapsules, microsperes hamwe nogutera kugirango irekurwe ku buryo burambye, kandi irashobora kandi gukoreshwa nkibikoresho byifashishwa mu mikorere y’ingirabuzimafatizo y’imyororokere no gutunganya amagufwa cyangwa ibikoresho byo gusana imyenda, nka suture yo kubaga, gushiramo, uruhu rw’ubukorikori, hamwe n’amaso y’amaso.

Gusaba

‌1. Ubuvuzi bwo kwisiga bwubuvuzi: PDLLA ikoreshwa cyane nkuzuza isura mubijyanye nubuvuzi bwo kwisiga kubera biocompatibilité nziza kandi yangirika. Irashobora gushimangira umusaruro wa kolagen y'uruhu, bityo igahindura uruhu, uruhu hamwe no kwiheba.

‌2. Ibikoresho byubuvuzi: PDLLA nayo ikoreshwa cyane mubijyanye nubuvuzi, nkibikoresho byapakiye ibiyobyabwenge byangiza imitsi ya coronari yangirika, suture yo kubaga, clips ya hemostatike, nibindi.

‌3. Ubwubatsi bwa Tissue: PDLLA ifite kandi ibikorwa byingenzi mubijyanye nubwubatsi bwa tissue, nko gutunganya amagufwa nibikoresho byo gusana amagufwa, ibyuma byubaka ingirabuzimafatizo, nibindi.

4‌. Kurekura ibiyobyabwenge kurekurwa: PDLLA irashobora kandi gukoreshwa mugusohora ibiyobyabwenge no gupakira bikomeza. Muguhuza nibiyobyabwenge kugirango ukore dosiye nka microsperes cyangwa microcapsules, kurekura buhoro hamwe nigikorwa gihoraho cyibiyobyabwenge birashobora kugerwaho, bityo bikazamura imikorere numutekano wibiyobyabwenge.

‌5. Imikorere yo gutesha agaciro PDLLA‌: PDLLA itesha agaciro gahoro gahoro, ituma itanga ingaruka zigihe kirekire zo kuvura mubikorwa byubuvuzi. Ibicuruzwa byayo byangirika ni aside ya lactique, amaherezo igahinduka mo karuboni ya dioxyde de carbone n'amazi, kandi ntabwo ari uburozi kandi ntacyo byangiza umubiri wumuntu.
