以国产Ｄ５．８０ｍｍ枪弹致伤狗下颌部，造成狗下颌硬软组织复合贯通伤，观察、分析该模型的基本特点。研究结果显示，５．８０ｍｍ枪弹以９６１．１８±８．９ｍ／ｓ的撞击速度在狗下颌至颌下造成入口小、出口大的硬软组织复合贯通伤，其能量传递率为８．５９％±３．１２％，枪弹撞击１５００μｓ后在伤道内形成瞬时空腔，狗伤后通过一般常规救治都能成活，局部伤及下颌骨体部、咀嚼肌、下齿槽神经血管束、面神经、牙齿等组织器官，伤道内可见严重的二次弹片伤痕迹，在下颌骨体内侧颌下区有一巨大的伤腔。该模型准确性、稳定性、重复性好，局部伤情具有典型的代表性，并有一定的复杂性，是一种较理想的颌面枪弹伤模型。
D5.80mm bullets were used to injure dogs’ jaws, resulting in the penetrating injury of the soft and hard tissues of the dog’s mandible. The basic characteristics of this model were observed and analyzed. The results showed that the 5.80mm bullets at the impact velocity of 961.18 ± 8.9m / s in the mandibular to mandibular jaw caused the small entrance, the export of large hard and soft tissue penetrating injury, the energy transfer rate was 8.59% ± 3.12%. After the bullets hit 1500μs, instantaneous cavities were formed in the injured tracts. After the traumatic injury, the dogs survived the general treatment, and local injuries were caused to the mandibular body, the masticatory muscles, the lower alveolar neurovascular bundles, the facial nerves and the teeth Tissues and organs, the pathological evidence of serious secondary shrapnel injuries, in the mandibular body submandibular area has a huge injury. The accuracy, stability and repeatability of this model are good. The local injury is typical and complicated. It is an ideal model of maxillofacial bullet injury.
