H. Lubbers et al., A NEW FINE-NEEDLE FOR EASIER, SINGLE HANDED, ULTRASOUND-GUIDED BIOPSIES, REQUIRING LESS ADVANCING FORCES INTO SOLID ORGANS, Zeitschrift fur Gastroenterologie, 31(9), 1993, pp. 484-485
A fine punch needle with a new bevelled geometry for easy, single-hand
ed, ultrasound-guided biopsies is presented. The needle requires a sig
nificantly lower advancing force compared with the commonly used punch
needles of the Menghini type. Since, therefore, our needle penetrates
the organs to be investigated easier, it enables the puncture of easi
ly movable (stomach, gut) and/or solid organs (kidney) with the yield
of sufficiently long punch cylinders. The first 196 biopsies were well
tolerated and histological diagnosis could be made in 94% of the case
