A special adapted retractor for the mini-sternotomy approach

Area of Science:

• Cardiovascular Surgery
• Medical Device Development
• Minimally Invasive Techniques

Background:

• Minimally invasive cardiac surgery offers an alternative to traditional open-heart procedures.
• Effective surgical exposure is critical for successful cardiac operations, especially in limited-access approaches.
• Existing retractors may not provide optimal visualization in ministernotomy procedures.

Purpose of the Study:

• To introduce and evaluate a specially adapted thoracic retractor for the ministernotomy approach in cardiac surgery.
• To assess the retractor's ability to provide adequate exposure and facilitate instrument manipulation.
• To determine the retractor's effectiveness in improving surgical access through limited incisions.

Main Methods:

• Development of a universally adjustable thoracic retractor designed for ministernotomy.
• Clinical application of the retractor in over 180 minimally invasive cardiac surgery cases.
• Utilizing a less invasive median sternotomy with a 6-9 cm incision as the primary approach.

Main Results:

• The retractor consistently provided excellent exposure, particularly below the incision edges.
• Its universally adjustable nature and low profile facilitated greater surgical access.
• Successful use in more than 180 patient cases demonstrated its clinical utility.

Conclusions:

• The developed thoracic retractor is effective for enhancing exposure in minimally invasive cardiac surgery via ministernotomy.
• The device offers significant advantages in terms of adjustability, visualization, and access.
• This specialized retractor supports the advancement of less invasive cardiac surgical techniques.
