Retraction device for clinical operation of neurosurgery department

The utility model relates to the technical field of medical instruments, in particular to a neurosurgical clinical operation retractor which comprises two groups of supporting mechanisms, two parallel beams are arranged between the tops of the two groups of supporting mechanisms, a plurality of groups of retractor mechanisms are arranged between the two beams, and the two groups of retractor mechanisms are arranged in parallel. Two connecting rods are installed at the top of the retracting mechanism, sliding mechanisms connected with the cross beam are arranged on the opposite sides of the two connecting rods, the sliding mechanisms, the connecting rods and the retracting mechanism are arranged, the sliding mechanisms and the cross beam are in sliding connection through sliding blocks and sliding grooves, and the positions of inverted-U-shaped blocks are fixed through first fixing bolts; the position of the retraction mechanism can be adjusted, the retraction mechanism is fixed in the fixing holes in the conn
