The application discloses a histopathological evaluation device for the healing degree of bone injury, and relates to the technical field of medical devices, pharmacodynamics and pathological diagnosis. The device comprises a microscope configured to capture an image of a stained bone tissue section; an image processing unit connected to the microscope and configured to obtain semi-quantitative histological measurement results and microscopic bone histomorphometry measurement results based on the image of the stained bone tissue section; the semi-quantitative histological measurement results comprise the state of callus bridging and fracture line, the composition and maturity of callus, new bone formation activity and bone remodeling and structure recovery state; the microscopic bone histomorphometry measurement results comprise the bone volume fraction and the proportion of osteoid surface; and a host computer connected to the image processing unit and configured to generate the bone injury healing condition according to the two kinds of measurement results. The application combines semi-quantitative histological measurement and microscopic bone histomorphometry measurement, and can provide an objective and quantifiable statistical device and method for the healing effect of bone injury.

The utility model relates to the technical field of auxiliary device, especially PFNA auxiliary device, it is mainly aimed at the process of reaming, reaming and inserting the main nail from the fracture line or the nearby position of the great trochanter vertex when carrying out PFNA internal fixation often causes the broken end separation, delays the fracture healing even does not heal, influences the patient recovery effect and the life quality, and the existing hook, towel forceps, bone holder or skin extrusion etc. direct or indirect mode maintains the reduction effect is not ideal problem, proposes the following technical scheme: including sleeve, the guide needle is slidably connected in the sleeve, a plurality of groups of through -hole are installed in the sleeve outer circle, a plurality of groups of through -hole are annular array distribution, the through -hole is used for guiding the kirschner wire, the positioning assembly is arranged in one end of the sleeve, the positioning assembly is used for limiting the guide needle, the utility model can effectively fix the broken end, accurately position the guide needle, promotes the fracture healing, improves the operation efficiency and the patient recovery effect and the life quality.

This invention relates to the field of medical image processing technology and discloses a method and system for identifying image anomalies in orthopedic diagnosis and treatment. The method includes the following steps: multimodal image acquisition and preprocessing, multimodal image collaboration and feature alignment, anatomically constrained feature learning, hybrid supervised learning optimization, and anomaly identification and result output. The system includes a multimodal image acquisition and preprocessing module, a multimodal image collaboration and feature alignment module, an anatomical constraint knowledge base module, a hybrid supervised learning engine module, an anomaly identification core network module, and an interpretability mapping and clinical workflow interface module. To improve the accuracy and comprehensiveness of identification, this method and system acquire CT and MRI dual-modal images through an adaptive acquisition platform and perform purification and calibration. Feature-level spatial alignment and adaptive weighted fusion are achieved through a differentiable affine spatial transformation network, enabling precise capture of various anomalies such as fracture lines and osteophytes.
