the liquid suction rod (1) comprises a first pipe body (11), an observation pipe (12) and a second pipe body (13) which are connected in sequence; assembling the first pipe body (11), the observation pipe (12) and the second pipe body (13) after cleaning and sterilization to form a liquid absorption rod (1); the liquid suction rod (1) is held in a pen holding state, so that a thumb is placed on the first supporting plate (2), a forefinger is placed on the supporting mechanism (3), and a middle finger is placed on the third supporting plate (4); extending the liquid suction rod into the preliminary gap between the brain tissue and the skull; applying a force on one side of the liquid suction rod (1) which is far away from the skull to enlarge the gap between the brain tissue and the skull, performing floating retraction on the brain tissue, changing the compression force of the liquid suction rod (1) according to the size of the required operation gap to expand the operation gap to a proper size, and converting the initial gap into the operation gap; the liquid sucking rod (1) is used for cleaning blood, effusion and tissues at the surgical gap; the flowing condition of the liquid in the liquid absorption rod (1) is observed through the observation tube (12), and the liquid absorption rod (1) is adjusted according to the flowing condition.

2. The surgical retraction cleaning device for brain according to claim 1 characterized in that: the supporting part comprises a supporting seat (31) and a connecting column (32), the supporting seat (31) is vertically fixed with the liquid absorbing rod (1), a limiting groove (311) is formed in the supporting seat (31), a spherical connector (321) is arranged at one end of the connecting column (32), the connector (321) is rotatably embedded into the limiting groove (311), and the other end of the connecting column (32) is connected with the second supporting plate (33).

3. The surgical retraction cleaning device for brain according to claim 2, characterized in that: the supporting mechanism further comprises a flexible contact piece (34), and the flexible contact piece (34) is arranged on the inner walls of the second supporting plate (33) and the limiting groove (311).

4. The surgical retraction cleaning device for brain according to claim 1 characterized in that: two ends of the observation tube (12) are respectively assembled and connected with a first tube body (11) and a second tube body (13).
