Both handheld and self-retaining retractors are commonly used in vascular surgical procedures. Gelpi-style retractors with single tips and Weitlaner-style retractors with rake tips that are blunt or sharp are used in incisions that are shallow. Sternal retractors that feature a rack with blades mounted to hinged arms are also common. Other popular retractors include rib spreaders such as Bailey and Burford, Crawford Aortic retractors, Henly carotid retractors and blades of varying depth. Krasky rake-style handheld retractors, and Wylie vein retractors.
