ABSTRACT:
A biopsy device for obtaining tissue specimens, particularly from endocervical canal. A cutting anvil, typically of a non-metallic material such as plastic, is carried at one end of an elongated shaft. An annular cutting blade, typically of a metallic material, on the end of a hollow shaft is telescoped on the shaft carrying the cutting anvil. The device includes a locking arrangement to lock the cutting edge of the device in engagement with the anvil during insertion of the device to the selected site and during removal of same from the body so that during insertion there is no inadvertent damage to tissue and, most importantly, no inadvertent loss and spreading of possibly diseased tissue and cells during removal. Further, the device includes an adjustment means whereby the size of the specimen may be selected prior to insertion in the patient.
