Biopsy needle and tissue collecting device

Abstract

There are provided a biopsy needle and a tissue collecting device that can collect the amount of biological tissue enough to make a pathological confirmation diagnosis with a simple structure and a simple operation. A tube (54) of a biopsy needle to be inserted into an endoscope forceps channel includes a puncture portion (56) that is provided at a distal end portion (55) of the tube (54) and has at least one blade distal end point (62), a slit (58) that extends toward a proximal end opening portion (52) from a distal end opening portion (50) of the tube (54), and a tissue excision cutter (60) that is provided at a proximal end (58C) of the slit (58) and is formed in a shape tapered toward a distal end of the slit (58) from the proximal end (58C) of the slit (58).
