Background

War wounds (mainly firearm wounds) are wounds that develop under specific conditions, and the clinical pathology and treatment techniques are in many ways consistent with normal wounds, but have their own characteristics. The war wounds are often classified from different angles according to the needs of the war wound treatment.

According to the injuring weapon and the injuring factor, the method can be divided into: cold weapon injuries refer to injuries caused by sharp edges or sharp pointed weapons (e.g. knives, swords, halts, etc.). Second, firearm injury refers to damage caused by a weapon (e.g., gun, cannon, etc.) fired by gunpowder. And thirdly, other war injuries, such as burns caused by combustion weapons, cold injuries caused under low-temperature environments, impact injuries caused by shock waves, chemical injuries caused by chemical weapons, radiation injuries caused by nuclear weapons and the like. The method can be divided into four types of tangential wound, rebound wound, blind tube wound and through wound according to the shapes of the entrances and exits. The inlet and the outlet are connected to form a groove shape and the groove shape is a tangent injury; the one with the inlet and outlet almost in the same place is called rebound injury; only the inlet without the outlet is a blind tube injury, and a bullet and a shrapnel are left in the body; and the through injury is both a population and an exit. After the fire-arm injury, the hard object prick or the knife puncture, the artery of the limbs and the blood vessel of the abdominal viscera are easily damaged, thereby causing the massive hemorrhage and finally leading the death of the wounded.
