Description

Technical Field

[0001] The invention relates to the field of wound treatment, in particular to a wound expansion and hemostasis device for medical surgery. Background Art

[0002] Under normal circumstances, bleeding caused by damage to small blood vessels will stop on its own within a few minutes. This phenomenon is called physiological hemostasis. Physiological hemostasis is one of the important protective mechanisms of the body and is the result of the interaction of multiple factors and mechanisms. The hemostasis process mainly includes three processes: vasoconstriction, platelet thrombosis and blood coagulation. Traumatic hemostatic powder can also help people achieve a certain degree of rapid hemostasis. Such powder is directly applied to the trauma site, which can directly promote blood coagulation at the wound and allow the blood at the wound to scab as soon as possible, so that it can quickly stop bleeding.
