Abstract: A needle tube includes: a tubular main body section; a distal opening section; a needle tip; a side hole disposed closer to the proximal end side of the main body than the tip; a side hole inner circumferential edge extending around the longitudinal axis of the main body where the side hole and the inner circumferential surface intersect; a side hole outer circumferential edge extending around the longitudinal axis of the main body where the side hole and the outer circumferential surface intersect; and an engaged surface formed between the side hole inner circumferential edge and the side hole outer circumferential edge to be directed toward the proximal end of the main body section and configured to lock biological tissue entering from the distal opening section, wherein the side hole forms an opening area smaller than that of the distal opening.

Abstract: A method for collecting tissue includes a body fluid removal step in which a body fluid inside a pancreatic cyst is moved to an outside of the pancreatic cyst, an injecting step in which a liquid different from the body fluid is injected into the pancreatic cyst, a collecting step in which the liquid is collected from the pancreatic cyst, and a separating step in which tissue of an inner wall of the pancreatic cyst, which is contained in the liquid collected from the pancreatic cyst, is separated from the liquid.
