Abstract
A vaginal speculum is disclosed in which a ratcheted linear motion of a thumb pad is translated into a complicated linear, rotational and retractive motion of the speculum paddles to provide anatomically correct motions for dilation of the vagina and the cervix without complicated two-handed adjustments of the speculum. Cam follower pins follow the contours of a cam slot to translate the linear motion into the required complicated motions of the speculum paddles. The ratchet permits easy locking at any degree of opening while unlocking is accomplished simply by depressing the thumb pad to disengage the pawl from the ratchet bars. A fluid reservoir is built into the speculum to capture fluids discharged during examination.
