Summary

This study tests a robot called MUSA-3 that helps surgeons connect tiny blood vessels, nerves, or lymph vessels during operations. About 30 adults needing this type of microsurgery will take part. The goal is to see if the robot is safe and works well compared to doing the procedure by hand.
