Types, Uses, and Innovations
In modern cardiothoracic and general surgery, the sternal retractor is one of the most vital surgical tools. Surgeons rely on it to provide a stable and clear view of the chest cavity, making complex procedures more precise and efficient. At Davicon Surgical, we focus on delivering top-quality surgical instruments that empower medical professionals to achieve successful outcomes.
This guide will explore the history, design, types, and applications of the sternal retractor while covering popular models such as the Cooley Sternal Retractor, Morse Sternal Retractor, Finochietto Retractor, and more.
What is a Sternal Retractor?
A sternal retractor is a specialized surgical instrument used to hold open the sternum (breastbone) during open-heart surgeries, thoracic procedures, and other major chest operations. Its primary role is to maintain access to the mediastinum and thoracic cavity while minimizing trauma and maximizing surgical visibility.
The sternal retractor name varies based on its design and inventor. For example, instruments such as the Cooley Sternal Retractor, Morse Sternal Retractor, and Finochietto Retractor carry the names of the surgeons who popularized or developed them.
Evolution of Sternal Retractors
In earlier days, rib spreaders served as the main chest-opening instruments. However, as cardiac surgery advanced, the need for more sophisticated and sternum-specific retractors grew. The development of the Cooley retractor and IMA retractor transformed thoracic surgery, allowing for less invasive access and improved patient safety.
Key Sternal Retractor Types
Understanding the different sternal retractor types helps surgeons choose the right tool for each procedure:
Cooley Sternal Retractor
Designed by Dr. Denton Cooley, this retractor features blades optimized for open-heart surgery. It allows stable spreading while minimizing tissue trauma.Morse Sternal Retractor
Known for its rigid design, the Morse retractor provides strong chest separation, making it ideal for long and complex procedures.Finochietto Retractor
Widely recognized, the Finochietto retractor is versatile and often used in both thoracic and cardiac procedures. Its ratchet mechanism allows controlled rib or sternal spreading.IMA Retractor
The Internal Mammary Artery (IMA) retractor is specifically used during bypass graft harvesting. It provides targeted exposure with minimal impact on the sternum.Rib Retractor
Although not strictly a sternal instrument, rib retractors play an essential role in thoracic surgeries by spreading ribs apart to improve visibility.
Each type serves unique surgical needs, ensuring precision and safety for both the surgeon and patient.
Importance of Sternal Retractors in Surgery
The sternal retractor is not just a spreading device; it is a critical surgical partner. Its importance lies in:
Offering surgeons a stable surgical field
Reducing the need for manual assistance
Improving access to the heart, lungs, and major vessels
Shortening operative times by maintaining visibility
Supporting minimally invasive approaches with specialized designs
Features of High-Quality Sternal Retractors
At Davicon Surgical, we emphasize durability, precision, and ergonomics in every retractor we manufacture. A premium sternal retractor should include:
Smooth and reliable ratchet mechanisms
High-grade stainless steel for long-term use
Adjustable blades for flexibility across patient anatomies
Lightweight yet strong design for ease of handling
Compatibility with both adult and pediatric procedures
Cooley Sternal Retractor: A Gold Standard
The Cooley Sternal Retractor stands out as one of the most widely used instruments in cardiothoracic surgery. Its broad blades and stable frame ensure consistent exposure, making it a gold standard in bypass, valve, and transplant operations. Many surgeons prefer it for its balance between force and precision.
Morse Sternal Retractor: Designed for Strength
When a procedure requires robust and steady separation, the Morse Sternal Retractor excels. Its rigid frame minimizes shifting during lengthy surgeries. This stability reduces surgeon fatigue and improves efficiency.
Finochietto Retractor: Precision in Action
The Finochietto Retractor is versatile and adaptable. Its ratcheting system allows gradual spreading, preventing excessive force on the sternum or ribs. Its reputation as a reliable rib retractor also highlights its multi-functionality in thoracic surgeries.
IMA Retractor: Essential for Bypass Surgery
Coronary artery bypass grafting (CABG) often requires harvesting the internal mammary artery. The IMA retractor is designed precisely for this task, offering clear exposure with minimal disruption to the sternum. Its specialized function makes it indispensable in cardiac surgery.
Rib Retractor: Supporting Chest Access
Though distinct from sternum-specific instruments, the rib retractor plays a complementary role. It enables surgeons to access lateral thoracic structures and is often used in combination with a sternal retractor for comprehensive exposure.
Choosing the Right Sternal Retractor
The selection of a sternal retractor depends on several factors:
Type of surgery (cardiac, thoracic, or vascular)
Patient anatomy (adult vs. pediatric)
Required level of exposure
Surgeon’s preference and experience
Instrument ergonomics and quality
Surgeons often combine multiple retractors, such as using a Cooley retractor for sternotomy and an IMA retractor for graft harvesting, to achieve optimal results.

FAQs
What is a sternal retractor used for?
A sternal retractor is used to spread the sternum during open-heart and thoracic surgeries, allowing surgeons better access to the chest cavity.
Which are the most common internal retractor types?
The most common types include the Cooley Sternal Retractor, Morse Sternal Retractor, Finochietto Retractor, IMA Retractor, and Rib Retractor.
What makes the Cooley Sternal Retractor unique?
It is designed for stability and precision during cardiac surgeries, making it one of the most trusted instruments in thoracic operations.
Is the Morse Sternal Retractor suitable for long surgeries?
Yes, its rigid and strong design makes it ideal for prolonged procedures requiring stable chest access.
