Medical Simulator Phantom with Optical Sensing for Puncture Training

The patent replaces mechanical sensor systems with optical sensing using cameras and computer vision algorithms. The system uses visual detection to track the intervention device's position and movement, substituting complex mechanical sensors with optical fields and image processing, thereby enabling automated feedback while maintaining training realism.

The patent introduces an intermediary processing system that bridges the phantom and the trainee. This system includes a processor that receives signals from sensors embedded in the phantom, processes the data to determine device position and procedure performance, and provides automated feedback through displays or audio outputs, enabling automated evaluation without requiring direct instructor intervention.

The patent merges the advantages of both phantoms and digital simulators by combining a realistic phantom model with automated digital evaluation systems. The phantom provides tactile realism and anatomical accuracy, while integrated sensors and processing systems provide automated feedback, creating a hybrid system that delivers both realism and automation simultaneously.

The patent implements a closed-loop feedback system where sensors embedded in the phantom detect the intervention device's position and movement, the processor evaluates procedure performance against predefined criteria, and automated feedback is provided to the trainee in real-time or after procedure completion, enabling self-correcting learning without instructor presence.

The patent enables the training system to serve itself by providing automated evaluation and feedback capabilities that do not require instructor intervention. The system automatically detects procedure performance through sensors, evaluates outcomes against predefined criteria, and provides corrective feedback, allowing trainees to learn independently while maintaining high learning quality.

The patent creates a universal training system that can evaluate multiple trainees simultaneously through automated feedback mechanisms. The same phantom and processing system can serve multiple users at different times or even concurrently, providing consistent evaluation criteria and feedback without requiring multiple instructors, thereby reducing complexity and cost while maintaining learning quality.

The patent enables each trainee to interact with the system independently, with the automated feedback system providing personalized evaluation and guidance to each user simultaneously. This self-service capability allows multiple trainees to receive individualized attention from the system without requiring proportional instructor resources, maintaining learning quality while increasing productivity.

The patent designs the training system to handle multiple users concurrently through universal evaluation algorithms and simultaneous feedback provision. The same hardware and software infrastructure can evaluate multiple trainees at once, providing consistent, high-quality feedback to each user without diluting the learning experience, thereby enabling one instructor to effectively supervise many trainees.
