IMA Sternal Retractor 100x20mm, 150x240mm

Clinical Application

Designed to facilitate exposure of the internal mammary artery (IMA) and provide parasternal retraction during median sternotomy and coronary artery bypass grafting (CABG). The narrower blade profile is intended for focused, atraumatic retraction along the IMA harvest plane, while the larger blade option provides broader chest-wall exposure when wider retraction is required. Proper use improves visualization of the thoracic internal mammary region and supports safe vessel harvesting.

Design & Configuration

Two blade size options allow the surgeon to select the most appropriate geometry for the operative field: a 100 x 20 mm profile for precise, localized retraction adjacent to the vessel and a 150 x 240 mm profile for wider sternal or chest-wall separation. The differing footprints help distribute retraction force over the desired contact area to reduce focal pressure on tissues and facilitate controlled exposure in both narrow parasternal spaces and broader chest openings.

Instrument Specifications
