长期使用手握式振动性工具可造成周围循环变化、创伤性血管痉挛性病变及周围神经病变。手的损伤性振动感觉很常见,其症状与腕管综合征相似;其病变可能在皮肤感受器,亦可能在近远端神经纤维或在神经细胞体。为此,作者以S-D大鼠为实验模型,研究不同神经纤维在振动时和振动后不同时间的超微结构。振动器用类似常用振动工具的频率和振幅。取电压为14V的电源,造成频率为82Hz、峰端振幅为0.21mm的振动。连续5天以4h/d振动
Long-term use of hand-held vibrational tools can cause changes in the surrounding circulation, traumatic vasospasm and peripheral neuropathy. Damage to the hands of the feeling of vibration is very common, the symptoms and carpal tunnel syndrome similar; its lesions may be in the skin receptors, may also be in the near-distal nerve fibers or nerve cell body. To this end, the author of S-D rats as an experimental model of different nerve fibers in the vibration and vibration at different times after the ultrastructure. Vibrator frequency and amplitude similar to commonly used vibration tools. Take a voltage of 14V power supply, resulting in the frequency of 82Hz, the peak amplitude of 0.21mm vibration. Vibration for 4h / d for 5 consecutive days
