摘要

FIELD: medicine.;SUBSTANCE: method involves slicing pathologically changed tissue with needle of 1.5-2 mm large diameter. The needle has longitudinal recess having sharp edges. Needle outlet opening is soldered. Slicing is carried out with the sharp edges in rotating the needle about its longitudinal axis. The pathologically changed tissues are sucked in into the longitudinal recess by creating rarefaction in the needle canal by pulling syringe piston back.;EFFECT: greater amount of bioptate taken; high reliability of puncture biopsy results.;1 dwg
