Computer assisted surgery navigation using intra-operative tactile sensing feedback through machine learning system

A method by a surgery navigation system for computer assisted navigation during surgery, the method comprising:

• training a machine learning model with intra-operative tactile sensing data that have been collected from previous surgeries;
• obtaining from a sensor circuit positioned proximate to a working potion of a tool, intra-operative tactile sensing data indicating a sensed characteristic of the tool contacting a location on patient anatomy within a surgical site;
• processing the intra-operative tactile sensing data through the trained machine learning model to generate intra-operative navigated guidance data including a level of force between the tool and the location on the patient anatomy;
• and
• providing the intra-operative navigated guidance data to a display device and/or to a surgical robot controlling movement of the tool,
• wherein the intra-operative navigated guidance data controls movement of the tool through the surgical robot.

A computer program product comprising:

• a non-transitory computer readable medium storing instructions executable by processing circuitry of a surgery navigation system for computer assisted navigation during surgery, the processing circuitry when executing the instructions is operative to:
• obtain from a sensor circuit, intra-operative tactile sensing data indicating a sensed characteristic of a tool contacting a location on patient anatomy within a surgical site;
• process the intra-operative tactile sensing data through a machine learning model that has been trained with intra-operative tactile sensing data that have been collected from previous surgeries to generate intra-operative navigated guidance data including a level of force between the tool and the location on the patient anatomy;
• and
• provide the intra-operative navigated guidance data to a display device and/or to a surgical robot to control movement of the tool,
• wherein the intra-operative navigated guidance data controls movement of the tool through the surgical robot, and
• wherein the sensor circuit if positioned proximate to a working potion of the tool.
