Area of Science:

  • Cardiovascular Surgery
  • Biomedical Engineering
  • Medical Device Design

Background:

  • Minimally invasive cardiac surgery necessitates specialized instrumentation for optimal surgical field exposure.
  • Atrial retractors are critical tools for both minimally invasive and open cardiac procedures, aiding in heart valve access.
  • Current atrial retractors on the market, while effective, present challenges such as complexity, bulkiness, and high cost.

Observation:

  • Existing atrial retractors can be cumbersome and expensive, posing limitations for widespread adoption or specific surgical settings.
  • There is a need for more accessible and user-friendly retractors in cardiac surgery.
  • The design process focused on simplicity and the use of common materials.

Findings:

  • A novel, exceptionally simple atrial retractor has been designed and developed.
