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

Clinical Application

This two-blade speculum is designed to provide controlled separation and sustained retraction of small orifices and superficial cavities during diagnostic examination and minor procedures. The narrow 4–8 mm adjustable aperture and extended 24 cm shaft make it suitable when a small, reproducible opening and additional reach are required—for example, localized ENT, lacrimal, ear canal or other delicate mucosal work where precision exposure and hands-free retention improve access and visualization.

Design & Configuration

The graduated ratchet allows the operator to set and lock the blade separation at reproducible increments, facilitating consistent exposure throughout a procedure and enabling assistants to maintain a steady field. The 4–8 mm adjustable range provides fine control for delicate tissues, while the 24 cm overall length gives extra reach to access deeper or less readily exposed areas without excessive instrument intrusion. The slender two-blade geometry minimizes tissue trauma and provides a clear line of sight for suction, instrumentation, or endoscopic adjuncts.
