The application relates to the field of computer-aided medical technology, and discloses a rehabilitation plan recommendation method for multiple fractures, which comprises the following steps: acquiring a first image for representing multiple fractures, the first image being an image in which multiple fracture position bounding boxes are marked on a preset human skeleton image; determining position information of a concurrent injury position according to the first image; and performing rehabilitation plan recommendation according to the position information of the concurrent injury position. The image in which multiple fracture position bounding boxes are marked on the preset human skeleton image is acquired, then the position information of the concurrent injury position is determined according to the image, and thus the rehabilitation plan recommendation can be performed according to the position information of the concurrent injury position. In this way, the rehabilitation training plan can be recommended for the multiple fracture user. The application further discloses a rehabilitation plan recommendation device for multiple fractures, an electronic device and a storage medium.

This invention relates to the field of medical device technology, specifically to a balloon device for minimally invasive reduction and fixation of intra-articular fractures. The device includes a cannula, within which an arthroscope slides and engages. A delivery tube for transporting the reduction balloon body also slides and engages within the cannula. The reduction balloon body includes a support balloon mechanism for transporting a support structure and a propulsion balloon mechanism for moving the fracture ends. The support balloon mechanism includes a clamping end and several movable ends. One end of the clamping end is detachably connected to the delivery tube, and a groove for placing the support structure is formed within the clamping end. The movable ends are fixedly connected to both sides of the clamping end. A base plate is fixedly connected within the groove, and several pressure sensors are fixedly connected to the base plate for measuring pressure data when the support structure contacts the fracture ends. The pressure sensors are electrically connected to a display panel for displaying the pressure data. This invention ensures accuracy during the docking of multiple fracture ends and improves the stability of the fixed fracture ends.

This invention relates to the field of oil and gas exploration and development, and discloses a method, apparatus, equipment, and medium for determining the area of ​​fracture current anomalies. It can generate conductivity imaging data and trajectory curve expressions for multiple fractures based on raw electrical imaging logging data from fractured oil and gas reservoirs. The conductivity imaging data and each trajectory curve expression are mapped to a predetermined three-dimensional coordinate system to generate a fracture trajectory curve corresponding to each trajectory curve expression and multiple discrete data points corresponding to the conductivity imaging data in the three-dimensional coordinate system. The three-dimensional coordinate system includes a depth axis, a wellbore expansion direction axis, and a conductivity axis. The background conductivity of the three-dimensional coordinate system is determined based on each discrete data point. Based on the background conductivity and each fracture trajectory curve, the current anomaly area of ​​each fracture is determined. This invention can effectively determine the area of ​​fracture current anomalies, enriching the methods for determining fracture current anomalies.
