A method and apparatus which improves the removal of cells from a cell sampling collection device used for uterine cervical pathology screening which may be inserted into or be an integral part of the collection vial containing preservative solution. The device may be constructed of a variety of materials, such as plastic, so long as the surface is smooth to minimize cell adhesion. The distal end of the device contains an aperture or slots in the base which allows the brush or other collecting device to be inserted into the preservative liquid through the slot and the sample to be removed by rubbing the brush against the edges of the slot. The proximal end of the device may have a mechanism for anchoring or seating it in the vial so it doesn't move when the brush or other collection device is rubbed against the slot to remove cells. The device may be anchored to the vial by screwing, snapping or press fitting it against the rim or sidewalls of the vial. After the sample is taken, and the cells removed from the brush or other collecting device, the device is discarded.

A cervical biopsy instrument that includes a central shaft defining a longitudinal axis and a stop extending laterally from the shaft. The stop typically is formed in substantially the shape of a circle in a plane disposed at substantially right angles to the central axis of the shaft. The instrument also includes an electrode extending from an endocervical portion of the shaft to the stop. The stop may be formed in the shape of a complete circle, or a partial circle. Any free ends are configured to be rounded and extend inwardly toward the shaft or away from the endocervical portion to prevent the presentation of sharp edges or the like which could be caught on irregularities of the uterine cervix. The stop may be affixed to the central shaft along a tangent, or ends of the stop may be affixed to the central shaft. In another embodiment, the stop encircles or partially encircles the shaft, with the shaft extending substantially through the center of the circle. In this embodiment, either one or two electrodes may be provided. Spokes support the stop with respect to the shaft. The spokes may be formed at an acute angle with respect to the shaft to extend away from the shaft toward the endocervical end thereof. These configurations allow the instrument to be rotated in either a clockwise or a counter-clockwise direction about the central axis of the shaft without fear of catching on the uterine cervix. In another aspect of the invention, a marker is provided on the stop to indicate the location of the electrode.
