Fracture Reduction Robot and Drive Control Method Thereof

Fracture Reduction Robot Assisted by 3D Interpolated Imaging

This technology generates 3D interpolated images of the corresponding healthy bone area for fracture reduction procedures. By overlaying and comparing these with images of the fractured area, it visualizes bone alignment in real-time and controls the reduction process via a drive unit.

During fracture and musculoskeletal repair surgeries, 2D imaging alone makes it difficult to accurately assess bone rotation or alignment, often requiring repeated X-rays for real-time intraoperative monitoring.

This technology acquires multi-angle images via an imaging unit (X-ray, MRI, CT) and uses an image processing unit to extract the diaphysis and generate 3D interpolated images. A matching unit calculates the alignment of bone contours, while a path calculation unit and drive unit move the bone to the target position, with the entire reduction process managed by a control unit.

Key Features:

• An imaging unit that captures multiple bone images at different angles for both the patient's fractured area and the corresponding healthy area.
• An image processing unit that generates 3D interpolated images for both the fractured and healthy areas using the captured bone images.
• A display unit that simultaneously shows the generated 3D interpolated images of both the fractured and healthy areas.
• An image processing unit that extracts the diaphysis from bone images and generates 3D interpolated images of the extracted diaphysis.
