Learning Spatial Awareness for Laparoscopic Surgery with AI Assisted Visual Feedback

Laparoscopic surgery constrains surgeons spatial awareness because procedures are performed through a monocu-lar, two-dimensional (2D) endoscopic view. Conventional training methods using dry-lab models or recorded videos provide limited depth cues, often leading trainees to misjudge instrument position and perform ineffective or unsafe maneuvers. To address this limitation, we present an AI -assisted training framework developed in NVIDIA Isaac Sim that couples the standard 2D laparoscopic feed with synchronized three-dimensional (3D) visual feedback delivered through a mixed-reality (MR) interface. While trainees operate using the clinical 2D view, validated AI modules continuously localize surgical instruments and detect instrument-tissue interactions in the background. When spatial misjudgments are detected, 3D visual feedback are displayed to trainees, while preserving the original operative perspective. Our framework considers various surgical tasks including navigation, manipulation, transfer, cutting, and suturing. Visually similar 2D cases can be disambiguated through the added 3D context, im-proving depth perception, contact awareness, and tool orientation understanding.
