Abstract
Abstract A specimen collecting method comprises an elongate clincical instrument having a blade and handle for collecting cells and tissues from body cavities, particularly for the detection of squamous carcinoma of the cervix. Two slanted spaced-apart edges on the blade tip describe a conical path during manual rotation in situ and gather specimens in troughs adjoining the edges. The blade tip is manually separable from the handle for forwarding to a pathology laboratory.
