To summarize the characteristics and investigate the mechanisms of boat propeller injuries so as to explore the identification methods between boat propeller injuries and corpse dismemberment.
More than 100 autopsy cases of boat propeller injuries were collected in a period between 1994 and 2005 in Huzhou district, Zhejiang province. The characteristics of injuries caused by propeller, including abrasion, wound, fracture and severed wound, and the characteristics of clothing, were retrospectively studied and summarized. The severed cross wound section of boat propeller injuries was compared with that caused by corpse dismemberment.
The boat propeller injuries were resulted from high-speed propellers with enormous splitting power and mechanical cutting, while corpse dismemberment were resulted from cutting and dismembering the body with sharp instruments. Due to the different mechanisms, the different strength of force and recoil force, the severed wound cross section had different characteristics.
Wounds caused by boat propeller injuries have their unique characteristics, distinguished from wounds of dismembered corpse.
总结船用螺旋桨损伤的特点，探讨其形成机制，以探寻船用螺旋桨损伤与碎尸案的鉴别方法。
收集1994年至2005年浙江省湖州市地区100余例船用螺旋桨损伤尸体检验案例，回顾性研究并总结螺旋桨造成的擦伤、创口、骨折及断创等损伤特点以及衣物特点，对比船用螺旋桨损伤的断创横截面与碎尸案断创横截面的差异。
船用螺旋桨损伤是由高速旋转、具有强大劈裂力的螺旋桨机械切割所致，而碎尸案是用锐器切割分尸形成。由于二者形成机制不同，作用力及反冲力大小不同，导致断创横截面呈现不同特点。
船用螺旋桨损伤创口具有独特特点，可与碎尸创口相鉴别。
