This document proposes using augmented reality to improve safety in laparoscopic surgeries by defining a safe zone for surgical tools to avoid critical structures. It will automatically extract surgical actions from video, train a network to predict the safe zone and flag unsafe actions based on tool proximity to critical areas and surgical workflow phase. The project aims to develop this for real-time use by capturing surgery videos, selecting areas of interest, training a network on tool distances and classifying risky actions, developing visualization and notifications, and implementing it during actual surgeries while getting user feedback.

3. Background and Motivation
AR can improve the safety of the patient and surgical outcomes for laparoscopic surgeries by defining a
safe zone for using surgical tools and avoiding critical structures.
The safe zone can be defined by utilizing the spatial and temporal registration between a patient, the
anatomical model tracked surgical instruments and the laparoscopic view of the patient.
We can automatically extract the semantic correlations of surgical actions and their impact, and train a
network for predicting the safe zone and flag unsafe actions.
i) Delineation of Safe Zone
ii) Is the tool at safe distance from critical structures?
iii) Which surgical workflow phase is being executed?
iv) Which tools perform what action through analysis of the pose data.
v) Is the action safe?
