Area of Science:

Surgical Robotics
Artificial Intelligence in Medicine
Data Mining

Background:

Intelligent surgical systems require robust surgical workflow models (SWM) for effective surgeon cooperation.
Acquiring sufficient training data for SWM is challenging due to limitations in physical surgery recordings, impacting knowledge scalability.

Purpose of the Study:

To develop a cost-effective and labor-efficient method for surgical workflow modeling to overcome knowledge scalability issues.
To enable intelligent surgical systems to acquire comprehensive SWM knowledge.

Main Methods:

A novel web-video-mining-supported surgical workflow modeling (webSWM) method was developed.
High-quality web videos were selected using topic and sentiment analysis for video quality assessment.
A statistical learning approach was employed to construct the SWM from selected videos, validated using robotic cholecystectomy surgery data.

Main Results:

The webSWM method demonstrated effectiveness in generating robust and reliable SWM knowledge from web videos.
Evaluation showed high video selection consistency (n-index ≥0.60) and surgical workflow matching degree (≥0.84).

Conclusions:

The webSWM method successfully models reliable SWM knowledge by mining abundant web videos efficiently.
This approach offers a promising solution for scaling knowledge for intelligent surgical systems with low cost and labor.
The method facilitates rapid acquisition of surgery-related knowledge from online video resources.
