The Disposable cytology brushes for endoscopy are clinically used to brush cell samples. The endoscopic cytology brushes is suitable for taking respiratory and digestive tract tissue samples under endoscope. Integrated brush head design, no possibility of bristles falling off; large expansion angle of bristles, sufficient sampling, improve positive detection rate; spherical head end is smooth and firm, bristles are moderately soft and hard, which can better reduce the stimulation and damage to the cavity wall; spherical head The end is smooth and firm, and the bristles are moderately soft and hard, which can better reduce the stimulation and damage to the cavity wall;
