摘要：
The present disclosure provides biopsy needles configured to maximize tissue sampling yield and further ensure collection of a cohesive unit of sampled tissue. The biopsy needles of the present disclosure provide a distinct tissue collection distal end configured to collect a full core of tissue sample and keep the full core intact. The distal end may include a distinct helical slot extending from an open distal end or a distinct cutting tip forming a coring feature.
