This invention provides a femoral neck fracture fixation system, relating to the field of orthopedic medical devices. Addressing the current problems of poor anti-rotation performance and cumbersome guide structure layout leading to long surgical times during femoral neck fracture fixation, this invention employs a fixation plate combined with a guide section. A guide groove is formed on the guide section to guide the inserted locking screw, eliminating the need for additional guide structures and saving surgical time. The fixation plate located on the femoral side provides restraint to the locking screw, improving its stability and anti-rotation capability.

This invention relates to the field of medical care technology and discloses a shape memory alloy (NiTi) hip replacement proximal femoral anti-fracture device. It includes a fitting body, with a first clamping arm fixedly disposed at the mid-front end of the fitting body. A fourth connecting mechanism and a sixth connecting mechanism are fixedly disposed at the front end of the fitting body, symmetrically arranged on the upper and lower sides of the first clamping arm. This invention is simple to operate, provides firm fixation, and is practical and reliable. NiTi shape memory alloy possesses shape memory effect, superelasticity, and good biocompatibility. Using NiTi shape memory alloy as the raw material to prepare the encircling device, it is in a flat, extended state at low temperatures and recovers its designed curved shape after heating, firmly and effectively encircling the lesser trochanter. It is mainly applied in hip replacement surgery for elderly patients with femoral neck fractures and osteoporosis, effectively preventing proximal femoral splitting during femoral prosthesis wear.

This invention relates to the field of intelligent medical imaging diagnosis technology, specifically to an AI detection system for occult femoral neck fractures based on two-stage artifact contrast learning. The system includes a data acquisition and construction module, an artifact enhancement contrast pre-training module, a detection network fine-tuning module, an inference and visualization module, and a physician-assisted image reading module. Training and testing data are acquired through multi-center cohort construction. An anti-interference radiographic feature encoder is obtained through artifact enhancement contrast pre-training. A single-stage detection network is then constructed by combining attention feature aggregation and dynamic upsampling modules to achieve precise detection. This invention can quickly output the probability of fracture presence, bounding boxes, and attention heatmaps. It can be embedded in clinical image reading workstations to provide real-time support, exhibits high sensitivity for occult femoral neck fracture detection, strong multi-center generalization ability, significantly improves physician diagnostic efficiency, reduces the risk of missed diagnoses, and features fast inference speed and strong interpretability, making it suitable for clinical application in emergency trauma scenarios.
