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.

Abstract

The invention discloses a 3D printing bionic bone trabecular structure lumbar vertebra fusion device for lumbar surgery, a manufacturing method and application. The device is characterized by comprising a solid support which comprises a horizontal surface soil support (1), a front end solid support (3) and a tail end solid support (4); the middle of the solid support is in a porous structure (2). The device is used for minimally invasive surgery, a human body cancellous bone structure is fully imitated, the fusion time is short, and a lot of autogenous bones are not required to be grafted. The osteogenesis effect is better by the aid of the support function.

Description

technical field [0001] The invention relates to a 3D printing bionic bone trabecular structure lumbar fusion device, a manufacturing method and an application. Background technique [0002] At present, in lumbar spine surgery, it is necessary to remove the diseased intervertebral disc and replace it with an artificial lumbar 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. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a 3D printed bionic trabecular bone structure lumbar fusion d...
