This paper describes evaluation results of a magnetically driven cytology brush applicable to a capsule-type medical device. The cytology mechanism is composed of a nut with a brush and bolt with a permanent magnet. When rotating magnetic fields are applied, the rotation of bolt due to magnetic torque is converted into the linear movement of nut. The periodic switching of the rotational direction of magnetic fields enables a reciprocating motion of the cytology brush. In order to improve cell collection by brushing, a small magnet was attached to the brush tip. The brush applied with a rotational vibration could enhance the performance of cytology.
