Abstract:
The author describes a pistol-like biopsy-sampling instrument by means of which most rapidly tissue cylinders--after a pre-destinable size in length and width--can be taken exactly and towards all sides with sharp edges without causing any contusion effects. The largest possible prevention of any damage to the adjacent tissue is guaranteed by a special shape of the cutting-knife. Besides, the tissue material taken can be put into a fixation fluid immediately after the sampling in one and the same working process without having to avail of an additional instrument. Correspondingly, the histological slides of such tissue samples are intact in their structure also in their marginal parts. The tissue samples are particularly suited also for electron-optical examinations, as they are kept live-fresh due to their immediate fixation.
