A computer-implemented method for automatically detecting energy tool activations in surgical videos has been outlined in a filed patent (Publication Number: US20240037385A1). The method involves receiving a surgical video, applying sampling windows to generate windowed samples, and utilizing a deep-learning model to infer activation/non-activation events with associated confidence levels. By identifying sequences of activation events based on these inferences, the method aims to accurately count and determine the duration of activation events during surgical procedures. The training of the deep-learning model involves annotated surgical videos with identified activation events, where labeled training data is generated by sampling the videos and assigning ground truth labels based on temporal locations relative to the activation events.

Furthermore, the patent also describes a system for automatically detecting energy tool activations, comprising processors and memory storing instructions for applying sampling windows, utilizing a deep-learning model, and identifying activation events in surgical videos. The system is designed to increment an activation count based on consecutive activation inferences and output the total activation count for the video. Additionally, a method for constructing a high-quality training dataset for training an energy tool activation detection model is detailed, involving temporal clustering of annotated activation events, computing statistical consensuses for clusters, and outputting these consensuses as ground truth for model building. Anomalies within clusters are identified and updated to ensure accuracy in the training dataset, ultimately improving the performance of the energy tool activation detection model.
