The invention discloses a medical absorbable polysaccharide composite material and application thereof. According to the medical absorbable polysaccharide composite material, starch with poor water absorbability is used as one material in the polysaccharide composite material; furthermore, a polysaccharide material with good water absorbability is added; the composite polysaccharide material is obtained through directly mixing, or through adding water, uniformly mixing and then carrying out freeze drying, without the need of cross-linking reaction. The material has the advantages of high waterabsorption rate, rapid water absorption speed, higher gel strength, good biocompatibility and the like, and can be directly used on wound surfaces with blood and for stopping bleeding of body surfaces, tissue organs in inner parts of bodies and in body cavities; the material can be used for rapidly stopping bleeding, can be absorbed by human bodies and has a sticky plugging effect. The material also can be further used as a post-operative anti-adhering material, a tissue healing promoting material, a surgical sealant, a wound suture-free tissue adhesive, a tissue filling material and a tissuedebridement material.
