The invention relates to the technical field of medical robot systems, and discloses a nerve plexus intelligent positioning anesthesia puncture robot system based on multi-modal fusion, which performs time-space synchronization on ultrasonic image flow and contact force data. The frequency domain analysis module extracts a main peak frequency by using optical flow field frequency domain transformation, and generates a probability mask for marking pulsatile tissues. The viscoelasticity verification module calculates phase lag parameters of visual deformation and contact force, identifies tissue rheological properties and calculates a dynamic damping coefficient. The deformation compensation module calculates a mechanical residual error based on a reference mechanical model, and inversely calculates the mechanical residual error into space deformation displacement of the tissue. The feedback control module combines the probability mask and the deformation displacement to generate a motion instruction. According to the invention, through multi-modal data fusion, precise identification of tiny blood vessels, dynamic identification of tissue attributes and real-time compensation of soft tissue conceding deformation are realized.

The application discloses an interpretable tongue diagnosis auxiliary diagnosis system based on knowledge graph fusion reasoning. The system obtains tongue diagnosis image data containing at least tongue surface image and sublingual plexus image, determines a plurality of preset tongue diagnosis regions and generates regional node features; constructs an image graph and updates the image graph by a first graph neural network to obtain image node features; constructs a traditional Chinese medicine knowledge graph containing tongue image, pathological factors, viscera, syndrome nodes and their relationships and updates the knowledge graph by a second graph neural network to obtain knowledge node features, projects and maps the image node features and the tongue image node features to the same embedding space, aligns the cross-modal modes according to a contrast learning loss to obtain cross-modal correlation; constructs a fusion graph based on the image graph, the knowledge graph and the cross-modal correlation and performs graph reasoning to output syndrome results and reasoning path information. Explicit connection of image regions and traditional Chinese medicine semantics and output of traceable paths reduce experience dependence and enhance interpretation and review.
