The control module is used to receive and process information from the two sensing modules to generate a comparison result of foot and ankle joint function posture. This device can simultaneously collect data from the patient's affected and unaffected feet, allowing medical personnel to perform repeatable quantitative assessment and diagnosis of foot and ankle joint injuries.

This application relates to the field of joint modeling technology, and discloses a method for assessing the risk of knee motion injury based on viscoelastic response finite element analysis. The method includes: acquiring magnetic resonance imaging data of the knee joint; performing grayscale thresholding to segment and reconstruct a three-dimensional structural model of the knee joint from sagittal and coronal images; performing surface smoothing to obtain a three-dimensional geometric model; setting bones in the three-dimensional geometric model as homogeneous, isotropic linear elastic bodies, cruciate ligaments and menisci as isotropic viscoelastic materials, and quadriceps tendons and patellar ligaments as stiff linear spring elements; meshing the three-dimensional geometric model; setting bone-to-bone and meniscus-to-femur contact as frictionless hard contact; setting the six degrees of freedom variation of the lower surfaces of the tibia and fibula to zero to establish a finite element model of the knee joint; performing knee flexion simulations at different angles and durations and detecting the viscoelastic response of the anterior cruciate ligament and meniscus; evaluating the influence of knee flexion angle and duration on the mechanical load of the knee joint soft tissues; and thus assessing the risk of injury. This application also discloses a knee sports injury risk assessment system based on viscoelastic response finite element analysis that implements the aforementioned method. This application can provide methods and basis for assessing the potential risk of knee joint injury during sports and for targeted treatment after injury.

The utility model discloses a kind of processing grinding machine for magnetic material, belong to magnetic material processing technical field, to solve the feeding of magnetic material workpiece (regardless of heavy) in prior art completely relies on artificial handling to workbench, artificial intermittent continuous handling, when facing heavier magnetic material workpiece, operator is extremely easy to appear exhausted phenomenon, this not only can make single feeding time gradually extend, disrupt normal production rhythm, workpiece will also be dropped, placed skew etc. Risk due to physical exhaustion, in addition, long-term handling heavy magnetic workpiece, the waist of operator, shoulder repeatedly bears excessive load, thereby increase the probability of occurrence of lumbar muscle strain, joint injury etc. Professional injury. Including grinding machine main body, the upper portion of the grinding machine main body is fixedly provided with an upper mounting frame, and a displacement mechanism is mounted in the middle portion of the upper mounting frame, the displacement mechanism includes a lead screw sleeve, and a fixed mounting frame is fixedly arranged below the lead screw sleeve.

The application provides a knee cartilage injury grading method and a storage medium thereof. The knee cartilage MRI image of a patient is acquired, and image region segmentation is performed on the knee cartilage MRI image to obtain a first image representing a patellofemoral joint region, a second image representing a medial femorotibial joint region, and a third image representing a lateral femorotibial joint region in the patient. Feature extraction is performed on the first image, the second image, and the third image to obtain a first feature set. The first feature set is input into a radiomics model, and the first feature set is subjected to cartilage injury grading evaluation and evaluation explainability analysis by the radiomics model to obtain a knee injury score and a knee injury grade of the patient and a visual evaluation report for explaining the generation of the knee injury score and the knee injury grade. The knee cartilage injury grading accuracy and explainability evaluation are realized, and the grading accuracy and the clinical application reliability are improved.

It has both preventive and therapeutic effects on osteoarthritis, and the traditional Chinese medicine composition containing *Achyranthes bidentata*, *Pueraria lobata*, etc., can be developed into a drug for the prevention and / or treatment of osteoarthritis.

This utility model discloses a high-density PU sole with massage and shock absorption functions, including an insole and a shoe cover wrapped around the insole. The insole has multiple ventilation holes running through it, multiple acupoint protrusions fixedly connected to the top of the insole, a support portion fixedly connected to the bottom of the insole with ventilation grooves, and multiple ventilation channels on the bottom of the insole. The insole also contains multiple honeycomb holes. This utility model, through the interaction of the ventilation holes at the top and the ventilation channels at the bottom, forms an efficient airflow circulation channel, which can effectively dissipate foot sweat, avoiding foot dampness, stuffiness, and odor problems, significantly improving wearing comfort. The honeycomb structure inside the insole interacts with the friction balls within the honeycomb holes, effectively dispersing and cushioning the impact force on the foot during walking, greatly reducing foot and leg fatigue and lowering the risk of joint injury.
