A modified starch material for biocompatible hemostasis, biocompatible adhesion prevention, tissue healing promotion, absorbable surgical wound sealing and tissue bonding, when applied as a biocompatible modified starch to the tissue of animals. The modified starch material produces hemostasis, reduces bleeding of the wound, extravasation of blood and tissue exudation, preserves the wound surface or the wound in relative wetness or dryness, inhibits the growth of bacteria and inflammatory response, minimizes tissue inflammation, and relieves patient pain. Any excess modified starch not involved in hemostatic activity is readily dissolved and rinsed away through saline irrigation during operation. After treatment of surgical wounds, combat wounds, trauma and emergency wounds, the modified starch hemostatic material is rapidly absorbed by the body without the complications associated with gauze and bandage removal.
A hemostatic powder comprising a hemostatic material, wherein the hemostatic material consists of biocompatible modified starch particles, wherein the biocompatible modified starch is modified by carboxylation or hydroxylation of glucose units in the starch, wherein the biocompatible modified starch particles are non-porous and substantially devoid of a microporous surface, wherein the powder has an adhesiveness sufficient to form a starch-blood coagulation matrix upon contacting a wound tissue.
