Researchers developed a novel collagen sponge hemostatic using bovine tendon. In vivo tests on rabbits demonstrated excellent hemostatic and adhesive properties for surgical applications.

Area of Science:

  • Biomaterials Science
  • Biomedical Engineering
  • Tissue Engineering

Context:

  • Soluble collagen is a key biomaterial for hemostatic applications.
  • Developing effective hemostatic agents is crucial for surgical procedures.
  • Lyophilization is a common technique for creating porous biomaterial scaffolds.

Purpose:

  • To extract soluble collagen from bovine tendon.
  • To prepare collagen sponge hemostatics via lyophilization.
  • To evaluate the hemostatic and adhesive properties of the prepared collagen sponge in vivo.

Summary:

  • Soluble collagen was successfully extracted from bovine tendon using an acid solution.
  • Collagen sponge hemostatics were fabricated using a lyophilization process.
