Inexpensive self-retaining retractor for minor surgical procedures

Area of Science:

• Surgical Innovation
• Medical Devices
• Biomedical Engineering

Background:

• Adequate surgical exposure is crucial but often requires manual retractors, which occupy personnel and obstruct views.
• Traditional self-retaining retractors can cause inadvertent tissue damage due to sharp tips.
• Existing retractors may not always be readily available or easily assembled in the operating room.

Purpose of the Study:

• To develop and evaluate a novel self-retaining ring retractor.
• To create a retractor that minimizes tissue damage and is rapidly constructible.
• To provide an efficient and safe alternative to traditional retractors.

Main Methods:

• Construction of a self-retaining ring retractor using materials from the sterile field.
• Evaluation of the retractor's ease of use and assembly time.
• Assessment of the retractor's force application to ensure finite and controlled tissue tension.

Main Results:

• The self-retaining ring retractor can be constructed in under 3 minutes.
• The device is efficient and easy to operate during surgical procedures.
• The retractor applies a known and finite force, preventing tissue damage.

Conclusions:

• The developed self-retaining ring retractor is a safe, efficient, and rapidly deployable surgical tool.
• This innovation addresses limitations of traditional retractors by preventing tissue injury.
• The retractor's design offers a practical solution for maintaining surgical exposure.
