The Surgical Robot Tracked the Phantom After Every Cut
Eight autonomous phantom resections produced negative margins across 77 cuts, with 1.61-millimeter mean absolute margin error.
Summary
Eight autonomous phantom resections produced negative margins across 77 cuts, with 1.61-millimeter mean absolute margin error.
Soft-tissue surgery changes the anatomy the robot is trying to track. This supervised research platform infers complete tumor, margin and kidney geometry from a single partial point cloud, updating its occupancy model as hydrogel tissue deforms and is cut. In eight consecutive open partial-nephrectomy phantom trials, dual robotic arms completed 77 electrosurgical cuts; every cut achieved a negative margin, with 1.61 ± 0.48 millimeters mean absolute margin error. These were patient-derived phantoms in a controlled open setting, not operations on people, and the results do not establish clinical autonomy.
