设计了生物适应性很强的力学控制装置──滑动机械加载控制器，对骨折断端没有应力遮挡，把肌肉动力与肢体负重力作为执行力学加载的源动力，通过压力传感器、多导传感放大器动态记录生理活动状态下断端受力情况及愈合过程中断端的应力状态。结果表明，同一时期内骨折断端压力随肌肉收缩及步态发生变化，不同愈合时间断端压力均值随时间的增加而逐渐增加，而滑动机械加载控制器上承载由术后当日平均２．４ｋｇ逐渐变小至术后五周平均０．７８ｋｇ。同时，通过解剖显微镜进行断端骨痂显微观察，显示断端完全由外骨痂包绕，从而认为骨折断端压力变化是肢体功能恢复，断端骨痂承受载荷的表现，提示临床骨折固定后应适时地进行功能锻炼，肌肉收缩、患肢负重可为断端提供最好的力学环境──生理应力状态。
The biomechanical control device, a sliding mechanical loading controller, is designed, which has no stress shielding at the broken ends of the fracture. It uses the muscle power and limb negative gravity as the source force to carry out mechanical loading. Through the pressure sensor, Amplifier dynamic recording physiological activities under the end of the stress situation and the healing process of the end of the stress state. The results showed that during the same period, the fracture pressure at the fracture site changed with the muscle contraction and gait. At the same time, the average pressure at the fracture site increased gradually with the increase of time. On the sliding mechanical loading controller, Gradually reduced to an average of 0.78kg after five weeks. At the same time, microscopical observation of fracture callus by dissecting microscope showed that the fracture end was completely surrounded by the outer callus, so that the change of fracture pressure at the fracture site was the function of limbs recovered and the load of fracture callus at the fracture site, suggesting that after the clinical fracture was fixed Should be timely exercise, muscle contraction, limb load can provide the best mechanical end-to-end mechanical environment ─ ─ physiological stress state.
