Problems solved by technology

In the case of insufficient autologous bone, the ilium needs to be removed, which will cause additional damage to the patient. If too much allogeneic bone filling material is implanted, there will be an inflammatory reaction or an allogeneic exclusion reaction, which will cause the failure of the operation.

Embodiment Construction

[0025] like figure 1 , figure 2 , image 3 , Figure 4 The shown 3D printed bionic trabecular structure cervical fusion device for anterior spinal cervical fusion and fixation surgery includes a solid support, which includes a horizontal plane solid support 1 and an axial solid support 3; the horizontal plane solid support 1 has a horizontal plane Supporting arc 4; the middle of the solid support is a porous structure 2, and the porous structure 2 is a microporous octahedral structure.

[0026] Because the periphery of the product of the present invention is solid, and the middle is a porous structure, the porous structure is a regular space octahedron. The cervical spine fusion device adopts a design that conforms to the anatomical structure of the human cervical spine. It adopts a circular reinforced solid support around the horizontal level, and adopts a support column structure at the human axial level to improve the overall compression resistance.

Abstract

The invention discloses an anterior spinal and cervical 3D print type artificial bone trabecula structure cervical fusion device. The device is characterized by comprising an entity support, the entity support comprises a horizontal plane entity support body (1) and an axial position entity support body (3), and a porous structure (2) is arranged in the middle of the entity support. The porous structure simulating the cancellous bone of the human body is manufactured in the 3D mode, a bone ingrowth support is provided, and the osteogenesis process is promoted; support pillars are additionally arranged on the periphery and on the sides to improve mechanical property, the elasticity modulus of the entity support is made to be close to that of a contact surface, and then shielding is avoided. Implantation of human bone is not needed, bone taking amount in surgery can be further reduced, the number of operative wounds is reduced, and surgery can be finished in a minimally invasive mode.

Description

technical field [0001] The invention relates to a surgical 3D porous structure imitating human cancellous bone, in particular to a 3D printing bionic bone trabecular structure cervical fusion device, a preparation method and an application thereof. Background technique [0002] At present, cervical spine surgery mainly includes anterior surgery and posterior surgery. In anterior surgery, it is necessary to remove the diseased intervertebral disc and replace it with an artificial cervical fusion cage. The fusion devices currently used clinically need to be implanted in a large number of autologous or allogeneic bones to achieve the purpose of intervertebral fusion. In the case of insufficient autologous bone, the ilium needs to be removed, which will cause additional damage to the patient. If too much allogeneic bone filling material is implanted, there will be an inflammatory reaction or an allogeneic exclusion reaction, which will cause the failure of the operation. Conte...
