We investigated wound tract extension of traumatic gunshot wounds in limb soft tissues as well as wound tract sonographic features and change-patterns when the limb position was changed. The experimental animals included 8 healthy crossbred pigs in the Chengdu plain region. Chinese Type 53 Carbine was used to establish the gunshot wound model of porcine soft tissues. Gunshot-injured zones in the soft tissues were dynamically observed at different time points using ultrasonic technology. Pathological examinations were performed for the corresponding regions for comparison and analysis. The internal echo of the wound tract was a pipe-like echo that changed over time. The wound tract extension changed with postural changes. The gas echo extended along the inside of the wound track, surrounding the fascia to further tissues. Ultrasonic imaging of gunshot wounds in pig soft tissues shows specific characteristics. The application of ultrasound technology may provide important imaging protection for gunshot wound debridement and postoperative unobstructed drainage, helping to improve the judgment and treatment of limb gunshot injuries.
我们研究了肢体软组织创伤性枪伤的创道延伸情况，以及肢体位置改变时创道的超声特征和变化模式。实验动物包括成都平原地区的8只健康杂交猪。使用53式步骑枪建立猪软组织枪伤模型。采用超声技术在不同时间点动态观察软组织内的枪伤区域。对相应区域进行病理检查以作对比分析。创道的内部回声为管状回声，随时间变化。创道延伸随体位改变而变化。气体回声沿创道内部延伸，围绕筋膜至更深层组织。猪软组织枪伤的超声成像显示出特定特征。超声技术的应用可为枪伤清创和术后通畅引流提供重要的影像学依据，有助于提高肢体枪伤的诊断和治疗水平。
