Lame de fibre optique MacIntosh 90mm – 92mm (Ref DI 01-140-01) — supplied from the Fizza Surgical instrument catalogue.

The Macintosh laryngoscope blade — designed by Scottish anaesthetist Robert Reynolds Macintosh in 1943 at Oxford — is the most widely used laryngoscope blade worldwide. The curved profile fits the tongue’s anatomy: the blade tip sits in the vallecula (the space between tongue base and epiglottis), and lifting the handle indirectly raises the epiglottis to expose the glottis. This indirect technique reduces the risk of damaging the epiglottis compared with the older Miller (straight) blade approach. Macintosh blades are manufactured in sizes 0 (neonatal) through 4 (large adult); sizes 3 and 4 cover most adult intubations. Modern fiber-optic Macintoshes have largely replaced bulb variants in operating theatres.

Every instrument is forged, machined, and finished at the Sialkot facility from German-origin stainless billet — austenitic 304 / 316 grades for non-cutting, mucosal-contact, and hollow-ware lines where corrosion resistance is the priority, martensitic 420 / 440 grades for cutting and edge-retention patterns where heat-treatable hardness matters, and 17-4 PH precipitation-hardened stainless for high-load orthopedic and implant-handling applications. Polishing, passivation, and final inspection are performed in-house under documented quality procedures aligned with ISO 13485:2016.
