Patent number: 8708931Abstract: This treatment tool for biopsy includes a needle tube, which having a first aperture and a second aperture. The first aperture and the second aperture communicate with the tubular space. The second aperture is provided in a side surface of the needle tube at more proximal end side than the first aperture. In a cross-section of the second aperture, a distal end circular arc portion of an end surface of the second aperture has a distal end side inclined surface that is inclined so as to be positioned gradually outwards of a radial direction of the needle tube towards the distal end side, and a proximal end circular arc portion of the end surface of the second aperture has a proximal end inclined surface that is inclined so as to be positioned gradually outwards of the radial direction of the needle tube towards the proximal end side.Type: GrantFiled: November 27, 2012Date of Patent: April 29, 2014Assignee: Olympus Medical Systems Corp.Inventors: Saori Takeuchi, Hideo Takachi, Yutaka Yanuma, Masatoshi Tonomura
