Robot-assisted camera control (RACC) shows similar surgeon motion efficiency and operative times compared to human camera drivers in laparoscopic surgery. Careful surgical suite setup may offer minor time improvements.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Robotics

Background:

  • Robotic systems are increasingly used in laparoscopic procedures.
  • Robot-assisted camera control (RACC) may offer advantages in view quality, precision, and cost.
  • The study aimed to evaluate RACC's impact on surgeon motion efficiency.

Purpose of the Study:

  • To compare surgeon motion efficiency between RACC and human camera control.
  • To assess the impact of RACC on operative times in laparoscopic Nissen fundoplication.

Main Methods:

  • Twenty pigs underwent laparoscopic Nissen fundoplication, randomized to human or RACC (AESOP 2000) control.
  • Procedures were performed by a single surgical fellow.
  • Operative times and surgeon motion were measured using inertial sensors and digitized data analysis.

Main Results:

  • Operative times were not significantly different between RACC and human control (80.2 ± 20.6 min vs 73.1 ± 15.4 min).
  • Statistically significant differences were only observed in setup and breakdown times, which constituted less than 15% of total procedure time.

Conclusions:

  • RACC demonstrates comparable surgeon motion efficiency and operative time to expert human camera drivers under standard surgical conditions.
  • Optimizing surgical suite setup may lead to marginal improvements in operative efficiency.
