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

Clinical Application

This speculum is intended to provide stable, adjustable retraction and sustained exposure of small surgical fields where precise control of aperture width is required. The combination of a fine tip profile with an indexed scale and ratchet-locking mechanism supports reproducible positioning during delicate procedures such as microsurgery, ophthalmic/ocular surface procedures, ENT work in confined spaces, or any case requiring controlled, incremental opening while minimizing tissue trauma.

Design & Configuration

The instrument features a graduated scale paired with a ratchet-style locking mechanism to allow incremental adjustment and secure fixation of the working aperture. A nominal 4/8 mm tip width provides a narrow profile for use in limited-access sites, while the 24 cm shaft length gives additional reach for deeper exposures. The ratchet reduces the need for continuous manual holding and helps maintain consistent tissue retraction throughout a procedure, improving surgeon ergonomics and field stability.
