Hydrostatic pressure bioreactor for intervertebral disc nucleus pulposus tissue bionic culture

The invention provides a hydrostatic pressure bioreactor for intervertebral disc nucleus pulposus tissue bionic culture. The hydrostatic pressure bioreactor comprises a base, a culture chamber and an upper cover, the culture chamber is fixedly connected with the base and the upper cover, a concave cavity is formed in the upper end of the base, a tissue carrying table is located in the lower portion of the culture chamber and fixedly connected with the base, and a culture solution exchange cavity is reserved between the lower end of the tissue carrying table and the bottom of the concave cavity. The tissue carrying table is of a step structure, the lower end is a large-diameter end, the upper end is a small-diameter boss, a plurality of horizontal grooves for a culture solution to pass through are formed in the upper end face of the small-diameter boss, and a plurality of solution passing channels for communicating the culture solution exchange cavity with the culture chamber are distributed on the large-diame
