This study introduces a novel preoperative planning method for robot-assisted minimally invasive surgery, improving surgical outcomes. The new approach enhances accessibility and hand-eye coordination, leading to shorter surgery times.

Area of Science:

  • Robotics in Surgery
  • Surgical Planning
  • Minimally Invasive Procedures

Background:

  • Robot-assisted minimally invasive surgery (RAMIS) overcomes limitations of traditional methods.
  • Effective preoperative planning is essential for successful RAMIS.

Purpose of the Study:

  • To propose and validate a novel preoperative planning method for RAMIS.
  • To enhance surgical efficiency and safety through optimized planning.

Main Methods:

  • A clinical evaluation system incorporating particle swarm optimization.
  • Utilized evaluation indices: accessibility, visibility, operability, and hand-eye coordination.
  • Validated using simulation and experimental verification for esophageal hiatal hernia repair.
