Cooley Rib Spreader for neonatal 12x15x70mm

Clinical Application

Designed for use in neonatal thoracic and cardiac procedures where precise, low-profile retraction is required. Provides controlled separation of the ribs to expose the pleural cavity, mediastinum, or neonatal heart during procedures such as patent ductus arteriosus (PDA) ligation, neonatal thoracotomy, and other limited-access chest surgeries. The compact dimensions are intended to match the small intercostal spaces and fragile rib structure of neonates, helping to improve visualization while minimizing soft-tissue and bony trauma.

Design & Configuration

The Cooley pattern delivers a narrow, low-profile retraction geometry optimized for neonatal anatomy. The paired blade configuration permits incremental adjustment of the working aperture to achieve the minimal required spread for adequate exposure. In neonatal cases, reduced blade height and a fine adjustment range are clinically important to avoid excessive force on ribs and costal cartilage while maintaining a stable field. The overall compact footprint eases placement and manipulation in confined pediatric chest cavities.
