This invention discloses a medical image segmentation method and system based on local Moran's index residual blocks, belonging to the field of intelligent medical image segmentation technology. By introducing multi-scale local Moran's index features, this invention effectively quantifies the spatial clustering patterns of key anatomical structures in shoulder MRI images, achieving accurate characterization of eight types of structures. A residual Moran's feature module is deeply embedded in the UNet architecture, and spatial feature utilization is enhanced at each level of the encoder-decoder, improving the model's adaptability and generalization ability to complex shoulder anatomy, making the segmentation results more robust and reliable in clinical applications. The constructed segmentation model can achieve end-to-end automatic segmentation of shoulder MRI images without additional spatial statistical preprocessing, offering advantages such as convenient deployment and high computational efficiency. It is suitable for rapid clinical diagnosis and surgical planning, and has significant application value in improving the intelligent diagnosis and treatment of shoulder joint diseases.

An implant insertion tool or tools interact with a user interface provided by a computer to guide the operator to insert the implant at a desired location and trajectory. The user interface may guide an operator through a registration process, a process for positioning the tip of the implant at the desired location, and a process for aligning the implant to have the desired insertion trajectory. The implant may be a medical implant such as a K-wire that is inserted into a bone, such as the glenoid of a scapula during shoulder arthroplasty or reverse arthroplasty.

This application provides a method for full-process safety situation awareness in live-line work on power distribution networks, including: acquiring real-time three-dimensional coordinates of each joint of the worker from a multi-joint skeletal tracking unit deployed on an insulated bucket truck; extracting the real-time angles between the lines connecting the shoulder and elbow joints and the elbow and wrist joints as the elbow abduction angle; generating a set of three-dimensional coordinates of key contour points on the worker's body surface based on the real-time three-dimensional coordinates of each joint, combined with preset skin layer thickness and contour outward distance at each skeletal node; comparing the real-time elbow abduction angle with a preset first threshold, triggering a dynamic recognition process when the elbow abduction angle exceeds the first threshold; and fusing the safety distance monitoring data for the most prominent part with the conventional safety distance monitoring data for the head and shoulder area to obtain a comprehensive safety distance monitoring result.

This invention provides a method for quantifying supraspinatus muscle fat infiltration using magnetic resonance imaging (MRI). Belonging to the field of MRI technology, this invention involves performing IDEAL-IQ sequence scanning on the shoulder joint of a subject to acquire multi-echo complex raw three-dimensional matrix data. A three-dimensional tensor unsupervised low-rank sparse decomposition blind-source water-fat separation model is used to decouple the real tissue signal from the field distortion phase term in the signal algebraic structure. After manually delineating the region of interest (ROI) of the supraspinatus muscle at a standard research level, a multi-component super-resolution unmixing model based on microscopic magnetic susceptibility anisotropy correction is employed to perform sub-voxel-level partial volume effect correction on the boundary voxels. Finally, the results are combined with artificial intelligence and MRI morphological typing to calculate and output a quantitative assessment report of the supraspinatus muscle fat fraction. This invention solves the technical problem of insufficient quantitative accuracy of the supraspinatus muscle fat fraction caused by phase contamination and systematic interference from partial volume effects in the water-fat separation results under shoulder joint edge scanning conditions with highly non-uniform main magnetic fields.

The present invention describes a shoulder rehabilitation device with rotary movement that can be placed on either the right or left shoulder of any person, regardless of arm and shoulder size. The device consists of three main parts: a frame, a forearm frame, and a movement mechanism. The two frames are placed on the shoulder and forearm of the shoulder to be rehabilitated, and the movement mechanism connects them, allowing the user's arm and shoulder to move. This movement mechanism is mounted on a prismatic cube-shaped base and is made up of bands that allow movement along the X, Y, and Z axes.The structure has protrusions that allow it to be attached to adjustment straps that help to place the device on either shoulder, to then start the type of therapy or movement which is programmed by means of a smart device that is linked to the device that is the subject of the present invention by means of a wireless communication module that is located in a control module.

A shoulder-reduction device and method of use are disclosed. The device is a portable, adjustable telescoping assembly configured to treat anterior or posterior shoulder dislocations by supporting the patient's body and shoulder during reduction. It includes an upper portion shaped to fit beneath the underarm, an upper telescoping tube, and a lower telescoping tube with a rigid support that rests on a chair or other stable surface. A flexible grip pad is attached to the rigid lower portion and is seated upon by the patient to stabilize the device.
