Ureteroscope imaging system and method
The present disclosure teaches determining kidney stone size based on calibration data generated from an endoscopic imager. During a lithotripsy procedure, an image is received by a deployed endoscopic probe. Based on the received imaging data, the generated calibration data, and known characteristics of the endoscope probe, one or more kidney stones in the image are identified and sized. And displaying the determined size value together with the kidney stone image.

Urinary calculus laser surgery anti-mishandling method and device based on visual AI model and storage medium
This invention discloses a method, device, and storage medium for preventing accidental injury during laser surgery for urinary tract stones based on a visual AI model. The method includes: acquiring and preprocessing a video stream captured in real-time by a monocular ureteroscope; inputting the image to be identified into a multi-task neural network model, simultaneously outputting a laser point detection box, a mucosal region segmentation mask, and a monocular depth map; determining the coordinates of the laser point center pixel based on the detection box, determining the coordinates of the nearest mucosal edge pixel based on the segmentation mask, and obtaining the corresponding first and second depth values from the depth map; inputting the coordinates, depth values, and intrinsic parameter matrix into a three-dimensional distance calculation model, reconstructing the three-dimensional spatial point coordinates based on the pinhole imaging formula, and calculating the actual physical distance; comparing the actual physical distance with dynamically adjusted safety and warning thresholds, and determining the risk level through fuzzy logic; generating control commands based on the risk level and sending them to the laser host to achieve graded early warning, power adjustment, or emergency interruption.
