The Cooley Sternal Retractor is a heavy-duty cardiothoracic chest spreader engineered for controlled median sternotomy separation during cardiac and thoracic surgery. Available in Child, Adult, and Extra Large profiles with calibrated rack-and-pinion mechanical drives, it provides expansive, non-slip mediastinal visualization.
The Cooley Sternal Retractor is a foundational cardiothoracic surgical instrument engineered specifically to provide reliable, symmetric sternal separation and wide mediastinal exposure during open heart and thoracic operations. Designed with a robust rack-and-pinion gear mechanism, this self-retaining retractor distributes heavy spreading force smoothly across both hemisternal margins, preventing localized bone fractures and costochondral dislocation.
Built to accommodate diverse patient anatomical profiles, the Cooley Sternal Retractor is manufactured in three precisely scaled configurations: Child Profile (145 × 140 × 21 × 45 mm, $354), Adult Profile (200 × 180 × 32 × 50 mm, $364), and an Extra Large Profile (178 × 152 × 102 × 29 mm, $374). Its anatomical blade curves and protective lips seat securely against the divided sternal cortices, maintaining a stable visual field throughout bypass cannulation, valve reconstruction, and graft anastomoses.
Forged from premium medical-grade surgical stainless steel with a reflection-free satin matte finish, Retractor Maker produces the Cooley Sternal Retractor to withstand repetitive hospital autoclave cycles, providing cardiac surgical suites worldwide with exceptional mechanical rigidity, smooth crank action, and lifelong durability.

The Cooley Sternal Retractor is a solid one-piece instrument, so its performance comes from blade geometry and handle ergonomics. It is made from surgical-grade stainless steel (aisi 304/420) for glare-free, corrosion-resistant service.
The Cooley Sternal Retractor is used in open cardiothoracic surgery to spread the divided sternum apart and maintain wide, hands-free exposure of the pericardium, heart, and mediastinal vessels.
It is indicated for coronary artery bypass grafting (CABG), aortic and mitral valve repair/replacement, thoracic aortic aneurysm repair, pericardiectomy, and thymectomy.
The instrument is forged from high-tensile surgical stainless steel with an anti-glare satin matte finish that eliminates optical reflections under surgical operating lights.
Yes. The entire Cooley Sternal Retractor is 100% reusable and fully validated for pre-vacuum steam autoclave cycles (134°C / 273°F). The mechanical rack and gear teeth should be cleaned and lubricated regularly.
Because this is an integrated mechanical chest spreader, each profile is sold as a standalone unit. Hospitals can order multi-profile sets to equip pediatric and adult cardiac suites.
Yes. Retractor Maker provides custom blade depths, specialized gear ratios, and laser marking for hospital asset tracking upon request.
In-stock instruments take 5 business days to inspect and dispatch, followed by 7 business days for worldwide express delivery. Back-order units take 17 to 20 business days to manufacture and 9 business days for delivery.
