Gruber Ear Speculum round 7.5mm, Fig.4

Clinical Application

This round 7.5 mm Gruber ear speculum is designed to provide direct visualization and controlled access to the external auditory canal during otologic examinations and minor aural procedures. It is used for inspection, cerumen management, microsuction, foreign body removal, ear packing, and procedures performed under loupes or an operating microscope. The 7.5 mm diameter balances working space and atraumatic fit for routine adult ear canals where a mid-sized speculum is preferred.

Design & Configuration

The round geometry concentrates the visual field and provides a continuous circular aperture that facilitates instrument access while minimizing sharp edges against the canal. The Fig.4 designation identifies its place in the Gruber sizing series; the 7.5 mm opening gives increased visibility and working clearance compared with smaller sizes while remaining conservative for atraumatic insertion. A polished internal surface aids visualization and helps prevent material adherence, and the smooth rim reduces mucosal irritation during use and manipulation.
