Cooley Rib Spreader 21x44mm, 150mm

Clinical Application

Designed for controlled retraction of the ribs and chest wall to provide surgical exposure of the pleural cavity and underlying thoracic structures. This instrument is used during lateral and anterolateral thoracotomy approaches, pulmonary resections, decortication, and other cardiothoracic procedures where precise, sustained separation of the intercostal space is required. The 21 x 44 mm blade pair offers asymmetric blade sizing to accommodate variable rib thickness and to improve visualization in confined operative fields.

Design & Configuration

The Cooley pattern features paired bladed arms with an adjustable spreader mechanism that enables incremental opening and stable hold. The 21 x 44 mm blade dimensions provide a balance between localized focal retraction and broader exposure; the 150 mm overall span gives appropriate reach for standard adult thoracic cavities while limiting excessive leverage on the ribs. Controlled, gradual spreading reduces trauma to costal cartilage and intercostal tissues and facilitates precise positioning of retractors during staged exposure.
