Kogan Speculum w/o scale ratchet 4/8mm 24cm

Clinical Application

This self-retaining Kogan speculum provides controlled, hands-free retraction and sustained exposure of narrow lumens and shallow surgical fields. The instrument is used where a small, precise aperture is required to visualize or access delicate structures—commonly employed in ENT procedures, lacrimal and select ophthalmic interventions, and other minor or microsurgical workflows that require a stable, narrow opening for instrumentation or endoscopic visualization.

Design & Configuration

The instrument features a ratchet locking mechanism to maintain consistent retraction without continuous manual support, improving surgeon control during delicate maneuvers. The 4/8 mm aperture options allow selection of a narrow or slightly wider opening to match the anatomy and procedural need. The 24 cm overall length provides extended reach for deeper or recessed fields while preserving fine control at the tips. The absence of a measurement scale removes visual clutter on the instrument shaft, useful when unobstructed sightlines are preferred.
