The invention discloses a wearable old hip fracture postoperative protection device which comprises a protection plate, an outer air bag and an inner air bag. The outer air bag and the inner air bag are respectively adhered to the outer side and the inner side of the protection plate; the wearable mechanism is arranged on the inner side of the protection plate, and the protection device can be worn through the arrangement of the wearable mechanism; the anti-moving mechanism is arranged on the protection plate, and the phenomenon that the protection device deviates after being worn is avoided through the arrangement of the anti-moving mechanism; the adjusting mechanism is arranged on the outer side of the protection plate, and adjustment can be conducted according to the weight of the patient through the adjusting mechanism. According to the wearable old-age hip fracture postoperative protection device, an extrusion plate extrudes to enable gas in a manual air bag to enter an inner air bag, the inner air bag pushes a bandage after being expanded, then the bandage makes full contact with the old-age hip fracture position of a patient, and then the protection device is suitable for patients of different sizes; and external force is decomposed through the arrangement of the outer air bag.

The invention relates to a device (1) for treating a bone fracture in a hip region of a patient, having an elongate base region (2) with a plurality of openings (3, 4), a tongue (5) protruding from the base region (2) and optionally connected via a transition region (12), and a bracket (6) protruding from the base region (2) and lying opposite the tongue (5). The tongue (5) is designed with a plurality of rows (7) of further openings (8, 9), wherein the rows (7) have a plurality of further openings (8, 9).

A fracture fixation system includes an implant defining a transverse bore extending along a bore axis, the bore being defined by first and second passages that each extend along the bore axis. The fracture fixation system further includes a lag screw configured to be inserted through the second passage, wherein a distal portion of the lag screw includes a thread. The fracture fixation system further includes a bolt configured to be inserted through the first passage, wherein a lateral side of the bolt defines a negative thread adapted to receive the thread of the lag screw. The negative thread includes a transition portion configured to align the thread of the lag screw with the negative thread of the bolt.

The invention provides a hip fracture operation type decision support system based on multi-modal artificial intelligence, and relates to the technical field of artificial intelligence medical assistance, and the system comprises a data obtaining module which is used for obtaining a preoperative pelvic CT image and electronic medical record structured information of a hip fracture patient; the feature extraction module is used for extracting features of a fracture key part in the preoperative pelvic CT image and encoding electronic medical record structured information into clinical features; the fusion prediction module is used for performing cross-modal fusion on the fracture key part features and the clinical features to obtain multi-modal fusion features, and inputting the multi-modal fusion features into a prediction model obtained by pre-training to obtain the risk probability that the hip fracture patient has clinical failure and needs secondary joint replacement. Therefore, clinical doctors can be assisted to make preoperative decision-making of hip fracture. The method has the beneficial effects that through cross-modal feature fusion, the objectivity, the stability and the clinical availability of an evaluation result are remarkably improved, and stable and reliable preoperative decision-making assistance can be provided for clinicians.

The invention discloses a postoperative delirium prediction method and device based on a least square support vector machine algorithm and electronic equipment, and aims to solve the problems that existing scale evaluation is high in subjectivity and instrument data is difficult to obtain. The method comprises the following steps: acquiring clinical and postoperative data of a patient from an EMR, HIS and LIS integrated system of a hospital according to time, crowd, treatment and result rules; carrying out cleaning, variable processing and 8: 2 division on a training verification set, and constructing a sample set; clinical data are used as input, POD results are used as output, a radial basis kernel function and grid search are selected to optimize LSSVM parameters to construct a model, Brier scores, AUC and calibration curves are used for verification, the POD probability of patients is output, and high-risk groups are recognized. The device comprises data acquisition, processing and prediction modules, and the electronic equipment comprises a storage and a processor. The method can solve the problem that in the prior art, the clinical practicability is limited when a score table or a medical instrument is used for evaluating the postoperative POD prediction of the old hip fracture patient.

This invention provides a wearable post-operative hip fracture protection device for the elderly, comprising: a front shield assembly and a rear shield assembly. The front shield assembly includes a front shield body, a front connecting strap, a front waistband, a Velcro fastener, a buckle, a front airbag, and a front air nozzle. The front and rear shield bodies can be separated, allowing for easier wearability. During use, the buckle is inserted into the buckle hole to stabilize the front and rear shield bodies, which are then secured together using the Velcro fasteners, enhancing the convenience of wearing the device.

This invention relates to a method and system for analyzing complex cytokine exosomes in bone marrow and blood from elderly patients with hip fractures. The method includes bone marrow sample collection (predicting the degree of fibrosis and adjusting the collection volume), pretreatment (optimizing sample composition), dynamic gradient bone marrow digestion (adjusting enzyme ratios according to the fibrosis index and monitoring in multiple dimensions), exosome extraction (ultracentrifugation and nanofiltration), and complex cytokine exosome analysis (constructing a seven-dimensional matrix, etc.). The system consists of units for bone marrow sample collection, pretreatment, dynamic gradient bone marrow digestion, exosome extraction, and complex cytokine exosome analysis. This invention solves the problems of exosome damage and low separation efficiency in traditional methods, and has advantages such as increased exosome extraction volume, preservation of integrity, enhanced reliability of analytical results, and improved standardization and reproducibility.
