Clinical Scorecard: Precision of Remote-Controlled Milling with Haptic Feedback in Surgical Settings

At a Glance

CategoryDetail
ConditionAccuracy in bone-related surgical milling procedures
Key MechanismsHaptic assistance via cooperative robotic systems to augment surgeon sensorimotor skills and support accurate plan implementation
Target PopulationSurgeons performing orthopedic, neurosurgical, and oral/maxillofacial bone surgeries, including novices
Care SettingSurgical operating rooms, including non-specialized hospitals and low-volume treatment centers

Key Highlights

  • Errors in anatomical landmark identification and distance judgment can cause serious patient safety issues and treatment failures.
  • Cooperative robots with haptic feedback combine robotic accuracy with surgeon decision-making, improving milling precision.
  • The minaroHD robot supports handheld, hands-on, and teleoperated modes with autonomous compensation for patient movement and submillimeter accuracy.

Guideline-Based Recommendations

Diagnosis

  • Assess surgeon skill level and experience to identify need for robotic haptic assistance in complex bone milling procedures.

Management

  • Utilize cooperative robotic systems with haptic feedback to augment surgeon sensorimotor skills during milling tasks.
  • Select appropriate human-robot interaction mode (handheld, hands-on, teleoperated) based on surgical requirements and environment.
  • Adjust haptic guidance parameters and arm support to optimize surgeon input accuracy during teleoperated milling.

Monitoring & Follow-up

  • Monitor master-side user input accuracy and slave-side robot positioning errors during teleoperated milling.
  • Evaluate milling path tracing accuracy and adjust haptic assistance stiffness and scale factors accordingly.

Risks

  • Inaccurate milling may cause implant misalignment, functional restrictions, damage to vessels or nerves, or incomplete bone removal leading to tumor recurrence.
  • Physical decoupling in teleoperation may reduce direct haptic feedback, requiring sensor-based force feedback systems.

Patient & Prescribing Data

Patients undergoing bone-related surgical procedures requiring precise milling

Robotic haptic assistance can improve surgical accuracy and safety, particularly benefiting novice surgeons and complex cases.

Clinical Best Practices

  • Provide surgeons with training and familiarization sessions using haptic devices before clinical application.
  • Customize arm rest support and motion scaling to match surgeon motor control capabilities for optimal input precision.
  • Incorporate real-time visual and haptic feedback to enhance surgeon spatial awareness during milling.
  • Employ cooperative robotic systems that allow surgeon control while compensating for patient movement.
