Cooley Rib Spreader 30x35mm, 140mm

Clinical Application

This Cooley rib spreader is designed to provide controlled, self-retaining retraction of the ribs and intercostal tissues to expose the thoracic cavity. It is intended for use in open thoracic procedures where precise, incremental spreading is required to access pulmonary, mediastinal, or cardiac structures. The compact blade dimensions (30 x 35 mm) support controlled expansion in limited access situations and narrow intercostal spaces, helping minimize excessive bone or soft-tissue tension during exposure.

Design & Configuration

Following the Cooley pattern, the instrument features opposing blades mounted on a self-retaining mechanism that permits gradual, incremental spreading and stable maintenance of the desired aperture. The bilateral blade configuration delivers even distribution of retraction force across the ribs, improving visualization while reducing point loading on bone and soft tissue. The 140 mm length provides adequate reach and working clearance for standard thoracic approaches while maintaining instrument stability at the operative field.
