Actuating the Specula Blades

The Bivalve Nasal Speculum can be manipulated into several positions. Four basic positions are outlined here:

1. Insertion/Resting position: This is the natural position that the specula will assume when no finger pressure is applied. It is also the same position used when inserting the specula into the nostril.

2. Both specula spreading at once: This is the standard movement of the instrument. By pushing both sections at their finger seat area, the nasal specula will spread as shown to the left.

3. Right or left blade spreading only: Push the finger seat area on the right or left section only.

4. Both specula spreading and pivoting: This can be done by pushing both sections at their finger seat area. While doing this, move your fingers such that both halves pivot around their attachement to the base. The pivoting option allows you to position the instrument to maximize your view and facilitate instrumentation.
