Which laryngoscope incorporates a hinged distal blade tip that can be flexed by a spring-loaded lever on the handle to elevate the epiglottis?

• A Bullard laryngoscope
• B Polio blade
• C Wisconsin blade
• D McCoy laryngoscope ✓

Explanation

The McCoy laryngoscope has a lever-operated hinged tip that flexes approximately 70 degrees to lift the epiglottis, converting many grade 3 views to grade 1 or 2, especially in patients with limited neck movement. The Bullard is a rigid fibreoptic scope with no hinged tip, the Wisconsin is a straight paediatric blade, and the polio blade has an adjustable handle angle for patients in a chest shell or halo, not a flexing tip.
