Absorbable medical surgical suture and preparation method thereof

The invention discloses an absorbable medical surgical suture and a preparation method thereof. The absorbable medical surgical suture is prepared from functional absorbable particles formed by blending an absorbable high-molecular polymer and nano pearl powder. According to the embodiment of the invention, the nano pearl powder is added into the absorbable medical surgical suture; therefore, the inflammatory reaction of the absorbable high-molecular polymer to tissues in the degradation process can be reduced; furthermore, the effect of the pearl powder can be effectively exerted; thus, the absorbable medical surgical suture has the effect of promoting collagen regeneration; the recovery of tissues around the absorbable medical surgical suture is promoted; and the beautifying effect is achieved. 本发明公开了一种可吸收医用手术线及其制备方法，所述可吸收医用手术线是由可吸收高分子聚合物和纳米珍珠粉共混的功能性可吸收颗粒制备而成的。本发明实施例通过在可吸收医用手术线中加入纳米珍珠粉，不仅能够减少可吸收高分子聚合物在降解过程中对组织产生的炎性反应，而且能够有效发挥珍珠粉的功效，从而使得可吸收医用手术线具有促进胶原蛋白再生的作用，促进可吸收医用手术线周围的组织的恢复，达到美容的效果。
