Claims

[Scope of utility model registration request]

In a cytology brush that is inserted into a treatment tool insertion channel of an endoscope to collect cells from a subject under direct vision of the endoscope, at least two edges are twisted together and inserted into the outer tube. It consists of an operating wire and a brush portion having an outer diameter larger than the inner diameter of the mantle tube provided at the tip of the operating wire, and the wire constituting this brush portion is made of a shape memory alloy. Characteristic cytology brush.
