Toxicological risk assessment confirms acceptability, and small animal model studies show no abnormalities in toxicity or sensitization. However, current evidence lacks clinical validation, particularly regarding efficacy and safety in chronic non-healing wounds.\n\nThis study integrates modern clinical evaluation methods with chronic wound staging theory to systematically investigate the effectiveness and safety of antimicrobial absorbable wound repair materials in treating chronic non-healing wounds.
