Kushandiswa

‌1. Kushongedza ganda: PDLLA inoshandiswa zvakanyanya semushonga wekushongedza kumeso mune zvekurapa nekuda kwekushanda kwayo zvakanaka uye kuora kwayo. Inogona kukurudzira kugadzirwa kwecollagen paganda, nokudaro ichivandudza kudonha kweganda, makwinya uye kuora.

‌2. Midziyo yekurapa‌: PDLLA inoshandiswawo zvakanyanya mumunda wezvishandiso zvekurapa, zvakaita semachira ane mishonga yekurapa stents dzemoyo dzinoora, sutures dzekuvhiya, hemostatic clips, nezvimwewo. Kushanda kwayo zvakanaka uye kuora kunoita kuti zvishandiso izvi zvekurapa zvive zvakachengeteka uye zvinoshanda zvakanyanya panguva yekushandisa.

‌3. Uinjiniya hwetishu‌: PDLLA inewo mashandisirwo akakosha mumunda weinjiniya yetishu, senge kugadzirisa mapfupa nezvinhu zvekugadzirisa mapfupa, mascaffolds einjiniya yetishu, nezvimwewo. Maumbirwo ayo ane maburi anobatsira kuti masero abatanidzwe uye akure, nokudaro zvichikurudzira kugadziriswa kwetishu uye kudzokororwa.

4. Kuburitswa kwemishonga kunodzorwa: PDLLA inogona kushandiswawo pakuburitswa kwemishonga kunodzorwa uye pakurongedza mishonga kwenguva refu. Nekuisanganisa nemishonga kugadzira mafomu emushonga akadai sema microspheres kana microcapsules, kuburitswa kwemishonga zvishoma nezvishoma uye kushanda kwenguva refu kunogona kuwanikwa, nokudaro zvichivandudza kushanda uye kuchengetedzeka kwemishonga.

‌5. Kushanda kwePDLLA pakuora: PDLLA inoora zvishoma nezvishoma, izvo zvinoita kuti ikwanise kupa mhedzisiro yekurapa kwenguva refu mukushandiswa kwayo mukiriniki. Chigadzirwa chayo chekuora ilactic acid, iyo inozopedzisira yagadziriswa kuita carbon dioxide nemvura, uye haina chepfu uye haina njodzi kumuviri wemunhu‌
