Area of Science:

  • Minimally Invasive Surgery
  • Robotics in Medicine
  • Interventional Cardiology

Background:

  • Conventional vascular interventional surgery (VIS) requires manual catheter manipulation under fluoroscopic guidance, posing radiation risks to surgeons.
  • A remote-controlled vascular interventional surgery robot (VISR) presents an opportunity for safer, more precise, and remote surgical interventions.

Purpose of the Study:

  • To evaluate the feasibility and safety of a novel master-slave vascular interventional surgery robot (VISR) for complex catheter navigation.
  • To assess the potential of VISR to improve surgeon safety and reduce procedure-related errors in vascular interventions.

Main Methods:

  • A master-slave robotic system was developed, featuring a supporting manipulator and a catheter navigator for precise catheter control.
  • Surgeons utilized a 3D vascular model for surgical planning and received tactile force feedback during remote operations.
  • The VISR system was tested on a glass vascular model and subsequently in an adult dog for in-vivo validation.

Main Results:

  • The robotic system demonstrated accurate catheter navigation within a complex glass vascular model, meeting clinical VIS requirements.
  • Successful remote robotic surgery was performed in an adult dog, accessing multiple cardiac and vascular targets.
  • While robotic surgery time was slightly longer than conventional methods, the system proved feasible and safe for target navigation.

Conclusions:

  • The vascular interventional surgery robot (VISR) is feasible and safe, enabling precise catheter navigation and positioning in specific vascular regions.
  • VISR technology significantly enhances surgeon safety by eliminating direct radiation exposure.
  • The robotic system has the potential to minimize surgeon-dependent errors, improving the overall safety and efficacy of vascular interventions.
