ABSTRACT:
In a vaginal speculum comprising two members each having a main limb, the main limbs can be inserted into a vagina whilst lying while and moved to pivot and move apart to maintain the vagina open for examination or treatment. One of the members has cheeks from which extend pins which engage slots in walls of a yoke of the other member; and each cheek has a toothed strip, a tooth on the adjacent wall of the yoke co-operating therewith to lock the speculum open. The yoke is resilient so that by deformation thereof the teeth can be caused to disengage the strips to allow closure of the speculum.
