## Indications for use
The Disposable Semi Automatic Biopsy Instrument is intended for obtaining percutaneous or surgical histological core samples from soft tissues such as breast, kidney, liver, lung and various soft tissue masses. The device is not intended for use in bone. The extent of histological abnormality cannot be reliably determined from its mammographic appearance. Therefore the extent of removal of the imaged evidence of an abnormality does not predict the extent of removal of a histological abnormality (e.g. malignancy). When the sampled abnormality is not histologically benign, it is essential that the tissue margins be examined for completeness of removal using standard surgical procedures
