Spare Insert for Miller Laryngoscope F/O/I/T #3 172mm

Clinical Application

This spare insert is a replacement blade insert for a Miller-style laryngoscope, sized to the #3 pattern and 172 mm overall length. The straight Miller profile is used to directly lift the epiglottis and expose the glottic opening during direct laryngoscopy, aiding visualization for endotracheal intubation. A spare insert is a practical component for operating rooms and anesthesia carts where rapid replacement of a worn or damaged illumination insert minimizes downtime and preserves clinical readiness.

Design & Configuration

The straight Miller geometry provides a rigid, narrow profile that permits direct elevation of the epiglottis rather than reliance on indirect displacement. The 172 mm length offers reach appropriate to the #3 Miller envelope while maintaining control and tactile feedback for the operator. The fiber-optic illumination channel integrated into the insert delivers light close to the distal tip, improving line-of-sight visualization while keeping the blade profile slim. As a replaceable insert, it lets facilities restore optical performance without replacing the entire blade assembly.
