A new robotic-assisted surgery (RAS) input device prototype offers intuitive control and seamless integration within the sterile field, enhancing surgeon performance and enabling novel robotic approaches.

Area of Science:

  • Robotics
  • Surgical Technology
  • Human-Computer Interaction

Background:

  • Robotic-assisted surgery (RAS) relies heavily on input devices for surgeon-robot communication.
  • Current RAS systems often position the surgeon's console outside the sterile field, limiting flexibility.
  • Surgeon proximity to the sterile site is crucial for intuitive control and workflow integration.

Purpose of the Study:

  • To develop and evaluate a novel input device prototype for RAS.
  • To enhance surgeon control and workflow integration within the sterile surgical environment.
  • To assess the performance of the prototype against a commercial device.

Main Methods:

  • A prototype RAS input device was designed based on laparoscopic surgery kinematics.
Keywords:
