This invention discloses an AI-assisted diagnostic system for CT rib fractures based on image recognition, belonging to the field of smart healthcare technology. It includes recognizing the patient's contour using thermal imaging data, constructing a respiratory model to analyze respiratory status, and automatically triggering CT image acquisition of the ribs at the optimal inhalation moment. Subsequently, artifact detection is performed; if qualified, the system is handed over to AI for intelligent fracture diagnosis, achieving a fully automated process from image acquisition to diagnosis. This invention uses non-contact thermal imaging to monitor respiration and body movement, constructing a respiratory model that integrates chest contour and airflow temperature changes, accurately identifying the optimal inhalation moment to trigger CT acquisition, reducing motion artifacts at the source and improving image quality. The system is highly robust, automatically determining the optimal acquisition time even under conditions of clothing or weak breathing, reducing reliance on patient cooperation, and is particularly suitable for rib fracture patients, improving examination success rate and efficiency.

The utility model relates to medical apparatus and discloses a combined bone plate, including rib bone plate and two embrace arms of installation on rib bone plate, through the mutual matching of first fixed hole, second fixed hole, first bone screw and two embrace arms, can adjust the interval of embrace arm in advance according to the condition of rib fracture of patient before implanting in the patient's body, after adjusting to the appropriate state, implements fixed mounting operation again, thereby avoid the tedious process of secondary adjustment in the patient's body, the simple structure, convenient operation, strong practicality, through the mutual matching of positioning hole, locating block, first bone screw and two embrace arms, only need to insert locating block into positioning hole in the adjustment process, then can complete fixation by installing first bone screw again, it is worth mentioning that, the whole adjustment and fixing process can be completed in the patient's body, improves the convenience and safety of operation operation.

The application discloses a rib fracture embracing type internal fixator, and relates to the technical field of orthopedics. The rib fracture embracing type internal fixator comprises an embracing plate, a plurality of embracing ends are arranged on the two long side walls of the embracing plate, the embracing plate is arranged in a C-shaped structure, is used for being transversely clamped at the fracture end of a fractured rib, the tensioning sheet is arranged in a C-shaped structure, the two end portions of the tensioning sheet can be arranged outside two opposite embracing ends on the embracing plate to form an embracing space, the space in the embracing space can be contracted and expanded for adjusting, and is used for accommodating fractured rib ends at different positions. The rib fracture embracing type internal fixator can stably fix the fractured rib position, and degradable material is adopted, so that secondary surgery is avoided.

The application relates to the technical field of rib fracture orthotopic fixation, and discloses a rib fracture orthotopic fixation device for thoracic surgery, which comprises a front fixing plate and a rear fixing plate, a strip-shaped box is arranged on the front fixing plate, a plurality of movable sliding blocks are arranged on the two sides of the strip-shaped box, first strip-shaped plates are fixed on the two sides of the strip-shaped box, side fixing plates are fixed on the sliding blocks, second strip-shaped plates are fixed on one side of the sliding blocks, a plurality of equidistantly-distributed miniature damping rods are fixed on the first strip-shaped plates, and a plurality of air bags are arranged on the front fixing plate; in the application, the speed of the side fixing plate is consistent with the speed of thoracic retraction, so that stable reduction is achieved, impact fitting between the side fixing plate and the thorax is avoided, beating is formed, the comfort of the patient is improved, the fixing position of the side fixing plate does not need to be frequently adjusted, automatic alarm can be realized when the patient performs large-amplitude action, and the purpose of automatically monitoring the movement amplitude of the patient can be achieved.

This invention discloses an ultrasound-guided method and fixation device for reducing and fixing fractured ribs, relating to the field of rehabilitation equipment. This ultrasound-guided method and device employs minimally invasive techniques, requiring only a small incision in the fracture area. Through this incision, a specially designed flexible bandage is precisely inserted and wrapped around the fractured rib using blunt dissection to avoid muscle tissue. Once tightened, the bandage provides continuous and stable external tension to the precisely reduced fracture ends, effectively counteracting the traction tension generated by respiratory movements and ensuring that the fractured rib maintains ideal alignment throughout the healing process. This technique avoids the extensive muscle stripping required in traditional surgery, significantly reducing intraoperative bleeding and postoperative pain, facilitating early ambulation, and greatly reducing the risk of complications such as pulmonary infection, achieving the treatment goal of minimal trauma and rapid recovery.
