The invention discloses a fixing device for extracorporeal circulation pipelines used in cardiac surgical procedures. The fixing device comprises a surgical drape and fixing components, wherein the fixing components comprise a plurality of magic tapes, every two magic tapes form a group, one magic tape in each group is stitched to the surgical drape, and the other one is not stitched; the two magic tapes of each group are connected through a cloth strip of which the length is equal to the circumference C of a pipeline required to be fixed herein; the two magic tapes of each group are folded in half and bonded to fix the extracorporeal circulation pipelines at the corresponding positions; and the stitching positions of the magic tapes on the surgical drape are on the path through which the extracorporeal circulation pipelines pass, and the number of the magic tapes is set according to actual needs. The fixing device can effectively fix all extracorporeal circulation pipelines and subordinate pipelines or pipes and effectively prevent the pipelines from dropping off, twisting and knotting, thereby providing a favorable environment for operations and remarkably improving the working efficiency.
