Classification: CPC G | IPC G

Claim 0:
1. An adaptive force guidance system for surgical training, comprising:
a hands-on physical interface that includes a fixture supporting an actuator-controllable surgical instrument for performing a surgical training task on a physical reality training arrangement using the actuator-controllable surgical instrument, the hands-on physical interface further including at least one sensor for receiving task performance data;
a processor configured to:
generate or acquire a surgical training task that includes a sequence of actions to be performed by a user of the actuator-controllable surgical instrument for performing a surgical training task on the physical reality training arrangement, each action in the sequence of actions being associated with guidance geometry specifying a recommended path to be traversed to perform the action;
while each action is being performed by the user of the actuator-controllable surgical instrument as part of the surgical training task, receive task performance data reflecting an amount by which the action being performed by the user causes a deviation from the recommended path; and
while each action is being performed by the user of the actuator-controllable surgical instrument, cause an adaptive feedback force to be applied to the actuator-controllable surgical instrument based at least in part on the task performance data that is received, the adaptive feedback force causing a reduction in the deviation from the recommended path.
