This video demonstration highlights proper techniques for mounting and removing blades, emphasizing careful handling to prevent injury and optimize surgical outcomes. Surgical scalpels, evolving from ancient instruments like Hippocrates’ macairion, are essential tools for precise incisions across various procedures. Modern scalpels feature blades of different shapes and sizes, designed for specific surgical needs—such as large incisions (No. 10), stab incisions (No. 11), and fine cuts (No. 15). Blades attach securely to handles varying by size and weight to ensure precision and safety.
