Ultrasonic Cleaning for Irrigating Purulent Substances during Laparoscopic Gastrointestinal Surgery

Area of Science:

• Surgical Technology
• Biomedical Engineering

Background:

• Laparoscopic gastrointestinal surgery requires effective removal of purulent substances from the abdominal cavity.
• Current irrigation technologies may be insufficient for optimal cleaning during laparoscopic procedures.

Purpose of the Study:

• To evaluate the efficacy and safety of ultrasonic cleaning technology for removing purulent substances in laparoscopic surgery.
• To assess the suitability of ultrasonic cleaning as a model for clinical application.

Main Methods:

• Surgical specialists evaluated purulent substance distribution using videos of pus-like model dirt.
• Cleaning tests were performed using a probe-type ultrasonic homogenizer on a miso-based model dirt attached to a silicon sheet.
• Ultrasonic cleaning efficiency was compared against high-pressure water flow cleaning.

Main Results:

• Ultrasonic cleaning removed model dirt within seconds when the test sample was submerged in water.
• This method demonstrated significantly superior cleaning performance compared to high-pressure water flow cleaning.
• The chosen model dirt, a miso mixture on a silicon sheet, proved suitable for testing cleaning efficiency.

Conclusions:

• Probe-type ultrasonic homogenizers show high potential for effective irrigation during laparoscopic surgery.
• Ultrasonic cleaning technology offers a promising advancement for improving outcomes in laparoscopic gastrointestinal surgery.
• Further validation through clinical trials is recommended for practical implementation.
