Abstract
Systems and methods for estimating contact force on an anatomical structure during a surgical procedure are disclosed. A system may include at least one processor configured to receive, from at least one image sensor in an operating room, image data of a surgical procedure and analyze the received image data to determine an identity of an anatomical structure and to determine a condition of the anatomical structure as reflected in the image data. The processor may select a contact force threshold associated with the anatomical structure, the selected contact force threshold being based on the determined condition of the anatomical structure, receive an indication of actual contact force on the anatomical structure, and compare the indication of actual contact force with the selected contact force threshold. The processor may then output a notification based on a determination that the indication of actual contact force exceeds the selected contact force threshold.
