摘要
The outer end (1) of the biopsy cannula (4) has two tips (2,3) each with two cutter flanks (5-7). One tip (3) is longer than the other one (2). All cutter flanks are sharply ground, obliquely from inside to outside. Pref. at least one tip is slightly inwards bent. The outer dia. of the cannula is 0.8 to 1.60 mm, and the cannula inner dia. is 0.6 to 1.4 mm. The cannula wall thickness is 0.1 to 0.2 mm. The tissue in the cannula is removed by retracting the mandrel (8). ADVANTAGE - Soft invasion and tissue removal without syringe, or vacuum extractor.
