This invention relates to the field of
medical device technology, specifically to a fixation brace for postoperative repair of lateral collateral
ligament injury of the
ankle joint. It includes a bionic support shell conforming to the dorsum of the foot,
ankle, and
heel. The bionic support shell comprises a dorsum segment, an
ankle segment, and a
heel segment conforming to the dorsum of the foot, ankle, and
heel. The bionic support shell is equipped with a multi-dimensional fit and fixation mechanism and an adaptive
rehabilitation adjustment mechanism. The multi-dimensional fit and fixation mechanism is electrically connected to a control module, which is also electrically connected to the adaptive
rehabilitation adjustment mechanism. The multi-dimensional fit and fixation mechanism includes an arch support component, a circumferential tightening component, and a heel limiting component. The control module is used to adjust the fixation force of the multi-dimensional fit and fixation mechanism, simultaneously and in conjunction with adjusting the
range of motion limits of the adaptive
rehabilitation adjustment mechanism. This invention achieves precise multi-point fit and fixation of the ankle joint, with precisely adjustable fixation force.
