材料与方法1.病理损伤模型:仿造上海体育学院病理损伤模型加以改进而成。打击锤质量为1kg,打击高度为30cm,受击面积为7cm~2。经推算,造模压强P=F/S中(F为打击力,S为受击面积),P=80牛顿/cm~2。损伤部位为家兔右大腿外侧。先将家兔固定于造模装置板上,右大腿去毛,将质量为1kg的打击锤牵拉至30cm高处,通过断电, Materials and methods 1. Pathological injury model: imitation Shanghai Institute of Physical Pathology injury model to be improved. Hammer mass of 1kg, striking height of 30cm, the attack area of ​​7cm ~ 2. After calculation, the model pressure P = F / S (F is the striking force, S is the affected area), P = 80 N / cm ~ 2. The injury site is outside the rabbit’s right thigh. First rabbit fixed on the modeling device board, the right thigh hair, the mass of 1kg hammer pulled to 30cm height, through the power,
