Cardiac surgery pericardial effusion drainage device and use method thereof

The invention relates to a cardiac surgery pericardial effusion drainage device and a use method thereof. The pericardial effusion drainage device comprises a telescopic pipeline fixedly used for being in butt joint with a blower, a tail pipeline of the telescopic pipeline is connected to an opening in the side wall of a shell, and a rotating block is rotationally connected to the inner wall of the shell; a traction mechanism allowing a drainage pipe to penetrate through and driving the drainage pipe to horizontally move back and forth in the shell is arranged on the rotating block, an annular space allowing hot air to flow is formed between the rotating block and the shell, and a plurality of wind shields are annularly distributed in the annular space on the outer wall of the rotating block; and a heating channel communicated with the annular space and the traction mechanism is formed in the position, between every two adjacent wind shields, of the outer wall of the rotating block. According to the pericardi
