A 2-blade baby Finochietto retractor is a specialized, self-retaining surgical instrument used in pediatric cardiothoracic surgery to gently separate and hold open the ribs of an infant or small child, providing access to the thoracic cavity for operations like cardiac surgery, lung procedures (lobectomy), and tracheoesophageal fistula repair. Its scaled-down, delicate design with curved, rounded, or fenestrated blades is crucial for minimizing trauma to the fragile tissues of a young patient.
