Abstract
The present disclosure generally relates to a biopsy needle configured to maximize tissue sampling yield and collect a unit of sampled tissue. The biopsy needle includes an elongate tubular body comprising a lumen extending therethrough from a proximal open end to a distal open end of the body. The distal end includes first and second tip portions extending therefrom and formed on opposing sides of the needle body. The first tip portion generally extends further from the distal end than the second tip portion, resembling a staggered configuration, resulting in an increased surface area of multiple cutting edges formed between the first and second tip portions on either side of the needle body. Additionally, each of the tip portion defines a penetrating point configured to pierce the tissue to be sampled and direct sampled tissue towards the lumen of the body to be excised by the cutting edges.
