Characteristics of Temporary Cavitation due to Two Kinds of Bullets on Soft Tissues of Dogs / 第三军医大学学报

ABSTRACT

This paper is to report the study of the characteristics of the temporary cavitations produced by two kinds of bullets on the soft tissues of dogs. The diameters of the bullets were 5.56mm and 7.62mm respectively. And the experiments were performed on 35 dogs. High speed roentgenography of the injured parts was taken 0.268-5.690 ms after injury. It was found that the cavity produced by 5.56mm bullet was formed earlier, existed longer, and was accompanied heavier soft tissue damage than that produced by 7.62mm bullet. It was also found that the characteristics of the temporary cavity were closely related to the amount of the energy transmitted from the bullet to the surrounding tissues, the construction of the bullet and its ballistic behavior in the tissues.
