The invention aims to provide a hydraulically-driven two-freedom degree bionic spinal joint module. The hydraulically-driven two-freedom degree bionic spinal joint module comprises an upper end cover and a lower end cover, wherein a two-freedom cross-shaft-type rigid universal joint and corrugated pipes are mounted between the upper end cover and the lower end cover; the two-freedom cross-shaft-type rigid universal joint comprises a cross shaft in the middle, universal joint forks connected with the cross shaft, and universal shaft bases connected with the end covers; a first gear pump and a first two-position four-way electromagnetic valve which are communicated with each other are mounted on the upper end cover; a second gear pump and a second two-position four-way electromagnetic valve which are communicated with each other are mounted on the lower end cover; four corrugated pipes are provided; the first two-position four-way electromagnetic valve is communicated with the first corrugated pipe and the second corrugated pipe respectively; and the second two-position four-way electromagnetic valve is communicated with the third corrugated pipe and the fourth corrugated pipe respectively. The hydraulically-driven two-freedom degree bionic spinal joint module stimulates rotation of a bionic spinal joint through hydraulic drive, so that change among a plurality of freedom degrees can be achieved and the motional capability of the bionic spinal joint is effectively improved.
