Autonomous orthopedics

A force-adaptive orthopedic surgical control system comprising:

• at least one orthopedic instrument configured to mechanically engage bone, an orthopedic implant, or an orthopedic fixation device during an orthopedic procedure;
• one or more sensors operatively coupled to the orthopedic instrument and configured to generate real-time mechanical interaction data representative of interaction between the orthopedic instrument and the bone, orthopedic implant, or orthopedic fixation device;
• a processing system configured to estimate, from the real-time mechanical interaction data, one or more biomechanical properties of skeletal tissue or a bone-implant interface;
• a predictive biomechanical modeling subsystem configured to predict a mechanical response of the skeletal tissue or bone-implant interface to a candidate force application based at least in part on the one or more biomechanical properties;
• a robotic or electromechanical actuation system configured to apply mechanical force to the orthopedic instrument, orthopedic implant, or orthopedic fixation device;
• and
• a closed-loop control architecture configured to generate a force-control command for the robotic or electromechanical actuation system based on the real-time mechanical interaction data and the predicted mechanical response,
• wherein the force-control command regulates at least one of magnitude, direction, rate, temporal profile, impact energy, vibratory energy, torque, displacement, or termination of the mechanical force during a force-mediated orthopedic assembly task.

A method of performing force-adaptive orthopedic assembly, the method comprising:

• mechanically engaging bone, an orthopedic implant, or an orthopedic fixation device using a sensor-integrated orthopedic instrument;
• acquiring real-time mechanical interaction data from the sensor-integrated orthopedic instrument;
• estimating one or more biomechanical properties of skeletal tissue or a bone-implant interface from the real-time mechanical interaction data;
• predicting, using a predictive biomechanical model, a mechanical response to a candidate force application;
• generating a force-control command based on the predicted mechanical response;
• and
• applying mechanical force using a robotic or electromechanical actuator according to the force-control command,
• wherein the force-control command is updated during the orthopedic assembly task based on additional real-time mechanical interaction data.
