Electric field stirring apparatus, electric field stirring method, and pathological sample manufacturing apparatus

A pathological sample manufacturing apparatus comrpsing:

• an electric field stirring apparatus in which a liquid disposed between a first electrode and a second electrode disposed to face each other is vibrated and stirred by an electric field generated between the first electrode and the second electrode, the second electrode having a groove formed along a first direction on an electrode surface facing the first electrode, the electric field stirring apparatus including a movement mechanism that reciprocally moves at least one of the first electrode and the second electrode relative to the other electrode in a second direction intersecting the first direction in a state in which the first electrode and the second electrode face each other during a period in which the electric field is generated;
• a stage section that includes a stage which functions as the first electrode of the electric field stirring apparatus and on which a substrate with a tissue sample fixed to a predetermined region is mounted;
• a reagent supply section that supplies a reagent to the substrate mounted on the stage;
• a cleaning section that supplies a cleaning liquid to the substrate mounted on the stage;
• a stage transport mechanism that functions as the movement mechanism of the electric field stirring apparatus when the cleaning section, the reagent supply section, and the electric field stirring apparatus are disposed in the second direction, and moves the stage in the second direction;
• and
• a control unit, wherein based on a pathological sample manufacturing protocol, the control unit controls driving of the stage transport mechanism, thus moves the stage to position facing the second electrode of the electric field stirring apparatus, and subjects the reagent or the cleaning liquid supplied to the substrate to electric field stirring.
