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.

This invention provides a method for improving interlayer defects in pultruded main beams of wind turbine blades and the resulting pultruded main beam. The method includes an improved process (1): when laying the pultruded main beam, the side guards of the tensioning fixture are removed first, and then it is hoisted and laid. The method of this invention for improving interlayer defects in pultruded main beams of wind turbine blades significantly reduces the number of interlayer defects in the blade pultruded main beam by optimizing the layout of the guiding auxiliary materials and optimizing the timing and method of injection. At the same time, it does not cause significant changes or other problems to the injection whitening quality defects, injection resin dosage, total injection time, blade mass distance, production efficiency, etc.
