Smarter robot, better surgery

Smarter robot​,​ better surgery

Problem being addressed

Many tasks in robot-assisted surgeries can be represented by finite-state machines​,​ where each state represents either an action (such as picking up a needle) or an observation (such as bleeding). A crucial step towards the automation of such surgical tasks is the temporal perception of the current surgical scene​,​ which requires a real-time estimation of the states in the finite-state machines.

Solution

A unified surgical state estimation model that incorporates multiple data sources including the kinematics, vision, and system events. The outputs are fed to a fusion model that makes a comprehensive inference.

Advantages of this solution

The model mproves the frame-wise state estimation accuracy of state-of-the-art methods by up to 11% through the incorporation of multiple sources of data. It demonstrates the advantages of a multi-input state estimation model through the comparison of single-input models’ performances in recognizing states with different representative features or levels of granularity in a complex and realistic surgical task.

Environment Sector

The methodologies that aim at improving the efficiency of robots performing human-like tasks can be applied during all sorts of disasters (fires, earthquakes, floods etc.) where human rescuers are currently working facing health and life threat.
