屈指肌腱滑车系统对屈指功能具有重要的生物力学特性。为了测定滑车的力学作用，本文设计了一种实验方法，从固定方法和测试方法上尽可能使离体手模拟在体手，通过切除和保留滑车，并采用屈曲功丧失率作为衡量指标，对滑车作用的大小进行了评定。实验结果证明本实验在方法和设计上是合理的 Flexor tendon pulley system has important biomechanical properties on flexor function. In order to determine the mechanical effect of the pulley, this paper designed an experimental method, from the fixed method and test methods as far as possible in vitro hand simulation in the hand, through the removal and retention of the pulley, and the loss of flexion as a measure of indicators, The size of the role of tackle was assessed. The experimental results show that the experiment is reasonable in terms of method and design
