The Metzenbaum Scissor (18 cm) is a classic, slender dissecting instrument utilized across general, vascular, thoracic, and gynecological surgeries for the precise separation of delicate soft tissue planes. Characterized by its long shaft-to-blade ratio (roughly 2:1), this 18 cm footprint—often referred to as a 7-inch model—offers deep abdominal or thoracic reach while providing maximum visibility and control without crushing surrounding anatomy.
