The Morse Rib Spreader is a lightweight thoracic surgery instrument engineered with multi-position movable blades for anatomical rib adaptation. Built with an anodized aluminum slide guide rail across four blade options from 22 × 27 mm ($239) to 55 × 28 mm ($299) and up to a 210 mm spread, it delivers rigid, non-traumatic chest wall separation.
The Morse Rib Spreader is an advanced thoracic surgical retractor engineered specifically to provide versatile, non-traumatic intercostal rib separation and chest wall exposure during open thoracotomy. Designed with an ultra-lightweight parallel slide guide rail and multi-position movable blades, this instrument allows surgeons to adjust blade orientation dynamically along the rib curvature, distributing distraction forces evenly to eliminate focal bone stress and costal fractures.
Built to provide maximum clinical flexibility while minimizing total instrument weight, this Morse Rib Spreader inventory scales across four unique movable blade sizing configurations: Option A ($239) features 22 mm × 27 mm lateral blades with a 200 mm maximum expansion track spread; Option B ($259) features 30 mm × 28 mm blades with a 210 mm maximum track spread; Option C ($279) features 42 mm × 28 mm blades with a 210 mm maximum track spread; and Option D ($299) features 55 mm × 28 mm blades with a 210 mm maximum track spread. The system mounts four movable angled blades (two per shank), secured by an integrated turning screw lock that rigidifies the frame to decrease hand fatigue.
Crafted with premium operating room-grade German stainless steel blades and high-strength anodized aluminum arms, Retractor Maker produces the Morse Rib Spreader to withstand repetitive hospital sterilization cycles, providing cardiothoracic suites, trauma centers, and lung surgery clinics worldwide with unmatched durability, corrosion resistance, and complete autoclave dependability.
