玻璃刺创形态学特点的初步研究

目的研究玻璃刺创的形态学特点。方法分别用3个厚度为0．31cm带尖状突起的啤酒瓶残端及3块厚度为0．29cm有尖的普通窗玻璃碎片按设定的不同方向刺击带皮猪肉组织，重复此过程3次，形成198例创口，观察、编号、拍照、测量各创口。结果198例创口的整体形态可分为5种类型，即“工”型、“”型、“”型、“上”型与“一”型，各型在不同刺击方向的分布上存在差异，其中前4种为主要类型，共约占总数的93％，其共同点为在损伤的中部出现了一段与损伤整体走向垂直的创口，啤酒瓶残端所致垂直创口的长度为0．31±0．Olcm（x±s），窗玻璃碎片所致垂直创口的长度为0．29±0．Olcm（x±s）。结论损伤中部有与损伤整体走向垂直的短创口是玻璃刺创中易出现的一种形态学特点，垂直创的长度与致伤玻璃的厚度具有一致性。

Initial investigation of the morphology of the glass stab injury

Objective To characterize the morphology of the glass stab injury. Methods Three fragments （0. 31 cm thick） of broken beer bottle and three sharp fragments（0. 29 cm thick） of flat glass were used to stab pig＇s skin tissue at different angle three times. The injuries were observed and measured. Results Based on overall shape of injury, a total of 198 injuries can he divided into five types, namely, type, type, type, _L_type and 一type. The injuries stabbed at different angle displayed differences shape. Among them, the first four types accounted for about 93% of the total. And these types all have a distinct wound in the middle of the injury, and the wound＇s direction is vertical to the direction of the overall injury. For injuries stabbed with broken beer bottles, the length of the vertical wound is 0.31±0.01cm（x± s）, and the length of the vertical wound caused by sharp fragments of flat glass, it is 0. 29±0, 01cm（x±s）. Conclusion The vertical wound in the middle of the overall injury is the most typical morphology of the glass stab injury, and the length of the vertical wound is consistent with the thickness of the glass fragment.
