Cooley Rib Spreader 37x49mm, 200mm Alum.

Clinical Application

Designed for controlled retraction of the thoracic cage, this Cooley-pattern rib spreader provides exposure for procedures that require intercostal space widening, including thoracotomy approaches for pulmonary, esophageal, and select cardiac procedures. The blade dimensions offer a broad contact area for stable rib separation while minimizing focal pressure on the intercostal margins.

Design & Configuration

The instrument uses a two-blade configuration with a manual ratchet mechanism to incrementally open and lock the blades at the desired gap. The Cooley pattern is widely used for its straightforward geometry: the symmetrical blades transmit evenly distributed forces across the ribs, improving operative visualization and access to the pleural or mediastinal cavities. The 37 x 49 mm blade footprint balances tissue support and working space, and the 200 mm overall length provides appropriate reach for standard thoracic exposures.
