The 6 levels of autonomy of surgical robotics:
Level 0: No autonomy
Level 1: Robot assistance
Level 2: Task autonomy
Level 3: Conditional autonomy
Level 4: High autonomy
Level 5: Full autonomy
Level 3, “conditional autonomy,” is the highest level of autonomy surgical robotics can achieve with current technology.
Here’s a breakdown of the six levels of autonomy in surgical robotics:
Level 0: No Autonomy: The robot functions purely as a passive tool, entirely controlled by the surgeon, and without any independent capabilities.
Level 1: Robot Assistance: The robot provides physical or cognitive assistance, such as stabilizing instruments or filtering tremors, but all decisions and actions are directed by the surgeon.
Level 2: Task Autonomy: The robot can autonomously perform specific tasks (e.g., suturing or cutting) once initiated by the surgeon, operating within predefined parameters.
Level 3: Conditional Autonomy: The robot can plan and execute tasks based on patient-specific data, with the surgeon overseeing and approving the plan before execution.
Level 4: High Autonomy: The robot can make medical decisions and perform sequences of tasks with minimal human intervention, though a surgeon remains available to supervise and intervene if necessary.
Level 5: Full Autonomy: The robot operates independently, performing entire surgical procedures without human input, including decision-making and execution.
FDA-cleared surgical robots operate at Level 1, assisting with direct human control.
A few systems have achieved Level 3, demonstrating conditional autonomy by generating patient-specific surgical plans that require surgeon approval before execution.
No surgical robots have yet reached Level 4 or 5 autonomy in clinical settings.
Advancements in AI and machine learning are driving research toward higher levels of autonomy. For instance, recent studies have explored hierarchical frameworks that enable robots to plan and execute complex surgical tasks autonomously, marking significant progress toward Level 5 autonomy.
