Abstract
The present invention provides a speculum including a body, an opening, a first blade pivotably secured to the body and a second blade that is integral with the body. The blades are located at opposed sides of the opening. The first blade is movable between a first retracted position in which it lies adjacent to the second blade and a second extended position in which it is spaced apart from the second blade. A mechanism is also provided to move the first blade from the first position to the second position. When the first blade is in the extended position, there is an inspection channel formed that extends through the opening and between the blades. The mechanism for moving the first blade is preferably located substantially outside the periphery of the opening when the first blade is in the extended position.
