Abstract

The utility model discloses a viscoelastic lumbar disc replacement structure, comprising an upper brake disc, a lower brake disc and a flexible support body arranged between the upper brake disc and the lower brake disc; the upper brake disc and the lower brake disc both comprise a disc body, viscoelastic plates respectively arranged on both sides of the disc body and an arc groove opened on the viscoelastic plate, a viscose claw is formed between adjacent arc grooves, an adhesive cavity is formed between the two viscoelastic plates, and the flexible support body is respectively arranged between the disc body of the upper brake disc and the disc body of the lower brake disc. The upper brake disc is connected to the flexible support body and then connected to the lower brake disc, and flexibility can be provided through the flexible support body, and the upper and lower brake discs can provide support, which can help relieve pain, restore normal spinal function of patients with degenerative disc disease, reduce wear, and thus reduce the probability of secondary revision as much as possible.
