Area of Science:

  • Robotics in Surgery
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Traditional robotic pedicle screw placement relies on optical markers, which are time-consuming and prone to errors.
  • Complex coordinate transformations in marker-based systems hinder surgical efficiency.

Purpose of the Study:

  • To develop and evaluate a novel markerless, structured light-based robotic system for pedicle screw placement.
  • To simplify the surgical workflow and reduce errors associated with coordinate transformations.

Main Methods:

  • A structured light camera was employed for direct tracking of surgical tools and bone anatomy, eliminating the need for markers.
  • A markerless "two-direction" robot-camera registration method and a feedback robot control strategy were developed.
  • A prototype system underwent precision validation and pedicle screw drilling experiments on synthesized cervical vertebrae phantoms.

Main Results:

  • Precision validation confirmed satisfactory system positioning accuracy.
  • All 42 drilled paths on phantom vertebrae successfully traversed the pedicles.
  • The mean entry point position error was 0.28 ± 0.16 mm, and the mean angle error was 0.49 ± 0.24°, meeting clinical requirements.

Conclusions:

  • The proposed structured light-based method is feasible for robotic pedicle screw placement.
  • The markerless system offers a simplified workflow and achieves high accuracy.
  • This approach eliminates the need for optical markers, enhancing surgical efficiency and precision.
