Abstract
The disclosure provides a medical sealant glue capable of promoting wound healing and a preparation method thereof. The medical sealant glue is formed by covalent cross-linking of two components after being physically mixed by a mixing tool, wherein the first component is a nucleophilic component, and the second component is an electrophilic component. The medical sealant glue has a gelation time of 1-10 s, a swelling ratio of 0-100%, a bursting strength of 100-250 mmHg, and a degradation time of 0.5-300 days. The nucleophilic component of the medical sealant glue contains exosome or hyaluronic acid and chitosan, and thus the medical sealant glue not only has the effect of promoting wound healing, but also has antibacterial and anti-infection effects.
