- Abstract
The wound ballistics focus on the treatment methods of gunshot injuries by developing on the personal ballistic protection equipment and increasing the effectiveness of ammunition. The scientific studies of Dr. Theodor Kocher are the initial origin of the modern wound ballistics, and also he formed the basis for the international the international war law with his studies. The modern wound ballistics is a common field of study of law, ballistics, and medicine. Because of this interdisciplinary structure, the science of wound ballistics works together with working groups which constitutes of various scientific field experts and specialized institutes. In this study, three basic mechanisms of gunshot wounds are emphasized; Penetration, Temporary Cavity (Blast Effect) and Fragmentation. Penetration is the first and basic effect of bullet and shrapnel on the tissues. A projectile must be hit by a velocity that can exceed the elasticity limit of the tissue to penetrate the tissue. This impact velocity is called "Threshold Velocity". In order for the target to be incapacitation, the projectile must penetrate the tissue and open the cavity at least 30 cm in length. The sum of the threshold velocities of each of the tissue is a "Critical Velocity". To calculate the critical velocity, the threshold velocities of each tissue should be calculated separately on the projectile and tissue that is along the cavity. The second important mechanism of gunshot injury is the Temporal Cavity resulting from the Blast effect. The amount of kinetic energy that a projectile transfers to tissues along the cavity determines the scale of the blast effect. Blast effect constitutes the main difference between the high kinetic energy rifle bullet and handgun bullet injuries. This difference is critical in the treatment of gunshot wounds and the design of ballistic protective equipment. The third firearm injury mechanism covered in this study is Fragmentation. The severity of the injury increases due to the fragmentation of the projectile outside the tissue or within the tissue. The effectiveness of treatment in firearm injuries will increase and ballistic protection technologies will be improved by analysing these mechanism. [ABSTRACT FROM AUTHOR]
