Summary:The utility model relates to the technical field of medical instruments, and discloses a vacuum negative pressure sucker liver suspension device which comprises a sucker. The negative pressure pipe is connected and communicated with the adsorption disc; a sealing structure is arranged in the negative pressure pipe and comprises elastic pieces, guide channels, deformation channels and deformation grooves, the two elastic pieces are symmetrically arranged in a cavity of the adsorption disc, the guide channels are formed in the end faces, away from the adsorption disc, of the two elastic pieces, and the deformation grooves are formed in the elastic pieces by arranging the elastic pieces; the gas in the deformation groove can push the wall surfaces, close to each other, of the two elastic pieces to deform, the mutually attached positions of the two elastic pieces are tighter, the sealing effect on the negative pressure pipe is better, and the situation that the adsorption effect in the adsorption disc is weakened
