Area of Science:

  • Reproductive Medicine
  • Minimally Invasive Surgery
  • Surgical Technology

Background:

  • Laparoscopic surgery is a cornerstone of reproductive medicine.
  • Surgeon fatigue and staff comfort are critical factors in surgical performance and patient safety.
  • The development of novel surgical instruments aims to improve operative efficiency and user experience.

Purpose of the Study:

  • To evaluate the impact of a multifunctional operative support arm on surgeon fatigue.
  • To assess short-term clinical outcomes in patients undergoing reproductive laparoscopic surgery.
  • To determine the staff user experience with the new surgical device.

Main Methods:

  • A single-center, parallel-group randomized controlled trial was conducted.
  • One hundred women undergoing laparoscopic surgery for endometriosis, hydrosalpinx, or ovarian cysts were randomized.
  • Surgeon fatigue, staff satisfaction, device comfort, and clinical outcomes were assessed.

Main Results:

  • Surgeon fatigue was significantly lower when using the multifunctional operative support arm compared to conventional support.
  • No significant differences were observed in operative duration, length of stay, postoperative infection, or ovarian reserve.
  • Staff reported higher scores for ventilation, temperature control, and comfort, though satisfaction differences were minor.

Conclusions:

  • The multifunctional operative support arm enhances staff-reported ergonomic comfort during reproductive laparoscopic surgery.
  • The device demonstrated no adverse short-term clinical effects.
  • Further validation with objective measures is recommended to confirm findings.
