Abstract

The invention provides an interbody fusion cage and a preparation method thereof. The interbody fusion cage includes a first porous structure layer, a second porous structure layer and a solid structure layer, wherein multiple pores are formed in the first porous structure layer, multiple pores are formed in the second porous structure layer, one end of the solid structure layer is connected to the first porous structure layer, and the other end of the solid structure layer is connected to the second porous structure layer; the first porous structure layer, the second porous structure layer and the solid structure layer are an integrated structure made of a polymer material, and the elasticity modulus of the solid structure layer is smaller than that of the first porous structure layer andthat of the second porous structure layer. The interbody fusion cage has a good elastic property and good integration with human skeleton series after implantation, and can slow down or avoid degeneration of intervertebral discs of adjacent segments to ensure a long-term curative effect.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to an intervertebral fusion cage and a preparation method thereof. Background technique [0002] The intervertebral disc is both tough and elastic. It is compressed when under pressure, and recovers after the pressure is removed. It is elastic and can buffer the shock of external forces on the spine and increase the motion range of the spine. However, the degenerative disease of the intervertebral disc has become a common disease and frequently-occurring disease. The compression of the spinal nerve caused by the intervertebral disc is also the main cause of clinical cervical, shoulder, low back and leg pain, which seriously affects the quality of life of patients. [0003] The existing treatment methods for intervertebral discs include simple herniated discectomy, intervertebral fusion, artificial disc replacement, and so on. However, the recurrence rate of simple herniate...
