Abstract

The invention provides an ankle biomechanical loading device. The ankle biomechanical loading device comprises a foot plate, a longitudinal shaft bracket, a transverse shaft bracket, a bottom support bracket, a bottom connector, a top connector and a vertical shaft sliding rod; the longitudinal shaft bracket is fixedly connected with the transverse shaft bracket; the front and rear ends of the foot plate are movably connected with the ends of the longitudinal shaft bracket, move along a transverse shaft and rotate around a longitudinal shaft; two ends of the transverse shaft bracket are movably connected with the botom support bracket and swing along the longitudinal shaft direction; the bottom support bracket is movably connected with the bottom connector and rotates around the transverse shaft, and the base connector rotates around a vertical shaft; the top connector moves up and down along the vertical shaft sliding rod and is used for fixing a foot specimen and adjusting the vertical pressure. Through three-dimensional six-degree-of-freedom adjustment of the foot plate, six states of plantar flexion, dorsal extension, introversion, extroversion, inward rotation and outward rotation of the ankle joint are simulated, so that a simulation result is closer to the real physiological condition of the ankle in the movement process.

Description

technical field [0001] The invention belongs to the technical field of medical experiment devices, and in particular relates to a foot and ankle biomechanical loading device. Background technique [0002] The ankle joint is an important weight-bearing joint in the human body. With the increasing participation of the social population in sports, the injury mechanism and treatment options of various ankle joints and their surrounding stable structures, including ankle joint fractures, have been controversial. Biomechanical experiments are a reliable means to explore the mechanisms of various ankle injuries and compare different surgical methods at this stage. The ankle joint has a high degree of matching and complex changes in the direction of motion and stress load. During normal activities, the ankle joint has plantar flexion, dorsiflexion, varus, internal and external rotation, pronation, and supination, which are more common in various postures. In the compound state, the...
