Problems solved by technology

Although this patent solves the problem of matching the elastic modulus of the fusion cage with the natural bone tissue and bone ingrowth, this single porous structure lacks fatigue resistance and is easily broken under the action of dynamic cyclic stress, which cannot meet the long-term clinical needs. needs

Embodiment 1）

[0042] Such as figure 1 As shown, the intervertebral fusion device of this embodiment is a structural part that is integrally printed with titanium alloy materials by a 3D printer. The cage is divided into a support structure part 1 and a pore structure part 2 according to different functions. The support structure part 1 and the pore structure part 2 are integrally fixedly connected together. The supporting structure part 1 is used to bear the external load, and the porous structure part 2 is used to guide the growth of new bone; the volume of the supporting structure part 1 accounts for 10% of the total volume of the cage.

[0043] Such as figure 2 As mentioned above, the support structure part 1 includes a mounting part 11 , a left bracket 12 , a connecting part 13 and a right bracket 14 connected in sequence. The mounting part 11 is provided with a pair of instrument slots 11 - 1 arranged front and back and an instrument hole 11 - 2 arranged along the left and right di...

Abstract

The invention discloses a porous titanium interbody fusion cage. The porous titanium interbody fusion cage is a structural component, and titanium alloy materials are integrally printed by the aid of a 3D (three-dimensional) printer to form the structural component. The porous titanium interbody fusion cage comprises a support structure and a pore structure. The support structure is used for bearing external load, and the pore structure is used for guiding new bone ingrowth. The volume of the support structure ranges from 5% to 20% of the total volume of the porous titanium interbody fusion cage. The pore structure is outwardly exposed on the upper side, the lower side, the front side, the rear side and the right side of the porous titanium interbody fusion cage in an open manner, and open growth spaces can be provided for effective growth of bones and the like. The porous titanium interbody fusion cage has the advantages that laser power, the scanning speeds and the scanning interval are controlled when a method for preparing the porous titanium interbody fusion cage is implemented, and accordingly the porous titanium interbody fusion cage can be integrally formed, has appropriate pore diameters and is high in porosity and good in strength; functions of two functional components of the porous titanium interbody fusion cage can be independently implemented by the functional components, the two functional components further can be matched with each other, and accordingly interbody therapy effects can be realized.

Description

technical field [0001] The invention relates to an implant for vertebrae, belongs to the field of intervertebral fusion and internal fixation, and in particular relates to a porous titanium intervertebral fusion device and a preparation method thereof. Background technique [0002] Lumbar disc herniation and cervical spondylosis and other symptoms of degenerative disc disease is a common and frequently-occurring disease in modern society, seriously affecting the quality of life of patients. Spinal fusion is one of the most widely used techniques in spinal surgery. It mainly promotes spinal fusion by establishing immediate spinal stability and implant osteogenesis, osteoinduction, and osteoconduction. At present, intervertebral fusion has become the main method for the treatment of lumbar instability, lumbar spinal stenosis, degenerative spondylolisthesis, degenerative scoliosis, pseudarthrosis and degenerative disc disease. The fusion device in the prior art is mainly divid...
