A novel device for cleaning the camera port during laparoscopic surgery

Area of Science:

• Surgical Technology
• Minimally Invasive Surgery
• Medical Device Development

Background:

• Obscured camera lens visualization is a frequent challenge in laparoscopic surgery.
• Contamination of the camera port is a primary cause of lens obstruction.
• Limited research exists on preventing port contamination during laparoscopic procedures.

Purpose of the Study:

• To develop and evaluate a novel device, the Endowiper, for cleaning laparoscopic ports.
• To assess the efficacy and safety of the Endowiper in simulated surgical conditions.

Main Methods:

• The Endowiper, constructed from rolled gauze, was tested for cleaning laparoscopic ports.
• Simulated surgical environments used pseudo-blood to contaminate port valves.
• The Endowiper's performance was compared against three existing port cleaning methods (wrapped gauze, small gauze, swab) in 280 trials across 12-mm and 5-mm trocar ports.

Main Results:

• The Endowiper achieved significantly higher complete port clearance rates (83.3% for 12-mm, 85% for 5-mm) compared to other methods.
• The Endowiper demonstrated a 0% trouble rate in both port sizes, outperforming existing methods.
• Statistical analysis confirmed the Endowiper's superior clearance and safety (p < 0.001 for 12-mm clearance, p < 0.01 for 5-mm trouble rate).

Conclusions:

• The Endowiper is a highly effective and safe device for cleaning laparoscopic ports.
• This innovative, inexpensive device offers significant advantages for laparoscopic surgeons.
• Improved port clearance by the Endowiper enhances surgical visualization and procedural safety.
