This invention discloses a medical gel for skin damage repair and its application, belonging to the field of skin repair technology. The medical gel is a gelatin-based gel containing a low molecular weight complex polysaccharide. This low molecular weight complex polysaccharide is obtained by mixing Dendrobium nobile, Dryopteris crassirhizoma, and Spartina alterniflora in a specific ratio, followed by degreasing with petroleum ether and ethanol, ultrasonic extraction, ethanol precipitation, and ultrafiltration purification to obtain a low molecular weight complex polysaccharide with a molecular weight less than 5000 Da. This invention also discloses the application of the aforementioned low molecular weight complex polysaccharide in the preparation of skin repair-promoting drugs or medical gels, which is particularly suitable for repairing full-thickness skin damage caused by mechanical injury. Its mechanism of action includes promoting the proliferation and migration of skin fibroblasts and angiogenesis of vascular endothelial cells. Therefore, the medical gel prepared by this invention has a significant wound-healing effect and can effectively accelerate the repair process of full-thickness skin damage.
