Sample processing apparatus and use method therefor

An automatic extraction device, comprising a sample processing apparatus comprising a uniform mixing mechanism and a magnetic attraction mechanism wherein

• the sample processing apparatus further comprises a plurality of sample tubes and a plurality of reaction tubes;
• the uniform mixing mechanism is configured to perform uniform mixing processing on a biological sample in a sample tube of the plurality of sample tubes and/or a biological sample in a reaction tube of the plurality of reaction tube;
• and
• the magnetic attraction mechanism comprises a magnet capable of moving relative to the sample tube and/or the reaction tube so as to perform magnetic attraction processing on the biological sample in the sample tube and/or the biological sample in the reaction tube, wherein
• the uniform mixing mechanism comprises a plurality of uniform mixing driving motors and a plurality of tube holders, the plurality of uniform mixing driving motors being in transmission connection with the plurality of tube holders in one-to-one correspondence;
• one of the plurality of sample tubes or one of the plurality of reaction tubes is provided in each tube holder;
• and
• each of plurality of uniform mixing driving motors is capable of being controlled separately to drive the corresponding tube holder to move.
