Surgical robots need better integration with patient data and imaging systems. This paper introduces Multi-Imager Compatibility for surgical manipulators, proposing new actuation principles for improved robotic surgery.

Area of Science:

  • Robotics
  • Medical Imaging
  • Surgical Technology

Background:

  • Current surgeon-driven surgical robots, like the daVinci system, have limitations due to their independent nature, failing to leverage patient data.
  • The true potential of surgical robotics lies in their integration with medical imaging and patient information systems.
  • Existing surgical robots face significant engineering challenges in compatibility with medical imaging environments, particularly MRI systems.

Purpose of the Study:

  • To define the concept of Multi-Imager Compatibility for surgical manipulators.
  • To outline the requirements for developing robotic systems compatible with multiple imaging modalities.
  • To propose novel actuation principles for enhanced surgical robot functionality in imaging environments.

Main Methods:
