Cooley spoon-shaped clamps are specialty surgical instruments specifically designed to provide atraumatic clamping of the blood vessels, especially during pediatric cardiovascular procedures. They have curved jaws in a spoon shape and serrated ends for safe holding of the vessels without inflicting damage on them. Made from top-grade German stainless steel, these instruments are light, reusable, and corrosion-proof. A ratchet lock mechanism ensures firm and stable occlusion of the vessel and is, hence, an indispensable instrument in delicate cardiothoracic and vascular surgeries.
