Abstract
A speculum, comprising a lower member including a handle and a lower blade extending at an angle from the handle, an upper blade movably engaged with the lower member by an angular adjustment mechanism so as to allow continuous adjustment of an angle between the upper and lower blades, and the angular adjustment mechanism comprising: a guiding arm, a rotational lever connected to the upper blade and operable by a user to change the angle between the upper and lower blades, the rotational lever being movably engaged with the guiding arm and configured to move relative to the guiding arm to continuously change the angle between the upper and lower blades, and a locking member movable between a locked position to lock a positional relationship between the rotational lever and the guiding arm and an unlocked position to release a locked positional relationship between the rotational lever and the guiding arm, wherein the locking member is configured to: (1) automatically lock the positional relationship between the rotational lever and the guiding arm along any position on the guiding arm, (2) automatically release the locked positional relationship during operation of the rotational lever in a first direction, and (3) be manually moved to the unlocked position to permit operation of the rotational lever in a second direction opposite to the first direction.
