High-resolution tweezers for cutting and coagulation reprocessing.

Area of Science:

• Surgical Technology
• Medical Device Reprocessing
• Infection Control

Background:

• High-resolution surgical instruments offer benefits like reduced operative time and tissue damage.
• Current guidelines often recommend single-use for these advanced devices.

Purpose of the Study:

• To assess the technical feasibility of reprocessing and reusing high-resolution surgical cutting and coagulation devices.
• To evaluate the safety and efficacy of reprocessing single-use devices.

Main Methods:

• Four Ligasure-Valleylab tweezers were subjected to a cleaning and hydrogen peroxide sterilization protocol.
• Device functionality was tested by a surgeon on beef tissue samples after contamination with common bacterial and fungal strains.
• Microbiological cultures were performed before and after sterilization to assess contamination.

Main Results:

• All microbiological cultures yielded negative results, indicating effective sterilization.
• Surgical device functionality was preserved across all four reuses.
• No thermal damage or significant handling issues were reported during functional testing.

Conclusions:

• High-resolution surgical tweezers can be safely reprocessed and reused up to five times (including initial use).
• Reprocessing maintains device integrity and sterility, offering a potential cost-saving and waste-reducing strategy.
• Further studies could explore reprocessing for other single-use high-resolution surgical devices.
