A novel robotic micro-drilling system navigates surgery using real-time drilling force feedback. This autonomous surgical robot precisely controls penetration, preventing damage to delicate structures during procedures like cochleostomy.

Area of Science:

  • Robotics
  • Surgical Technology
  • Biomedical Engineering

Background:

  • Cochleostomy requires precise control to avoid damaging the endosteal membrane.
  • Existing autonomous surgical robots often rely on pre-operative data, limiting real-time adaptability.
  • Controlling surgical tools in flexible tissues presents challenges due to movement and interface variations.

Purpose of the Study:

  • To introduce a robotic micro-drilling technique for surgery.
  • To demonstrate real-time navigation using reactive drilling forces.
  • To achieve precise control of drill penetration in micro-surgical procedures.

Main Methods:

  • A robotic micro-drilling device was developed and deployed for cochleostomy.
  • The system navigates by analyzing transients in reactive drilling forces.

  • It discriminates cutting conditions, tissue state, and detects the medial surface before drill break-out.

    • Main Results:

    • The autonomous surgical robot successfully navigated in real-time without pre-operative data.
    • The technique enabled discrimination of tissue conditions and movements.
    • Controlled drill break-out or avoidance at the medial surface was achieved with high precision.

    Conclusions:

    • This is the first autonomous surgical robot to use real-time force feedback for navigation.
    • The developed system offers unprecedented precision in controlling fine penetration during micro-surgery.
    • The technique addresses challenges in flexible tissue manipulation and patient movement during surgery.
