钝性暴力致脾破裂的发生机制研究

脾破裂与外伤之间因果关系的判断是法医学鉴定中一个十分常见但又非常棘手的问题。探究脾破裂的机制是解决上述问题的必要的理论基础。本文收集了２５例钝性暴力致脾破裂的案例，对脾破裂的部位与暴力打击部位及方向的关系进行了分析、整理，探讨了人体各部位遭受暴力作用后脾破裂的特点，及钝性暴力导致脾破裂的机制，发现脾破裂的机制主要包括直接暴力冲击以及脾脏在受外力作用后撞击胃、隔肌、脊柱、肋骨和胸后壁等两类，并指出对脾破裂机制的进一步研究将成为法医学鉴定研究工作中的一项重要课题。

MECHANISM OF SPLENIC RUPTURE BY BLUNT FORCE

In forensic medical examination, the, determination of therelation between spontaneous and traumatic splenic ruptureis a difficult work. The study of mechanism of splenic rupture Will render a necessary theoretic basis for handling theproblcm. We collectal 25 cases of splenic rupture causedby blunt force, analyzed the relation between rupture siteof spleen and direction of blunt force. We discovered thatthe mechanism of splenic rupture rests on two princi principles, the hit of the force and the collision of spleen to peripheral viscera, spinal column and ribs.
