Area of Science:

  • Robotics
  • Surgical Technology
  • Artificial Intelligence

Background:

  • Current robotic suturing research focuses on single-instrument movement planning, neglecting task allocation among multiple instruments.
  • Efficient task assignment is crucial for multi-instrument robotic suturing operations.

Purpose of the Study:

  • To propose a novel method for autonomous suturing task assignment to multiple instruments.
  • To optimize the scheme for assigning suturing tasks to instruments under specific constraints.

Main Methods:

  • Developed a comprehensive evaluation index to determine the optimal task assignment scheme.
  • Integrated constraint conditions into the evaluation index for realistic optimization.

Main Results:

  • Successfully applied the method to an experimental duodenal ulcer repair suturing operation.
  • The proposed method identified the optimal suturing task assignment scheme, validated by a surgeon.

Conclusions:

  • The developed method enables autonomous suturing task assignment for robotic surgery.
  • This advancement significantly improves the operational intelligence of surgical robots.
