Embodiment 1

[0033] The embodiment of the present application discloses a bone filling block with a tantalum metal porous structure layer, referring to figure 1 , including a substrate 1 and a tantalum metal porous structure layer 2 on the surface of the substrate 1 . Compared with titanium alloy, tantalum metal has better biocompatibility, smaller elastic modulus, more effective reduction of stress shielding, higher porosity, and more conducive to inducing bone ingrowth, which is more conducive to bone remodeling. It is an ideal bone implant material.

[0034] Wherein, in this embodiment, the matrix 1 is a network glassy carbon body, the tantalum metal porous structure layer 2 has a pore diameter of 200-800 μm, a wire diameter of 100-700 μm, and a porosity of 50%-80%.

[0035] Reticular glassy carbon is a three-dimensional network microporous material composed of glassy foam. It has low density, high chemical stability, specific surface area, and high structural strength. The pore diamet...

Abstract

The invention relates to a bone filling block with a tantalum metal porous structure layer, a manufacturing method and an application. The filling block comprises a base body and the tantalum metal porous structure layer on the surface of the base body. The manufacturing method comprises the step of forming the tantalum metal porous structure layer on the surface of the base body. The beneficial effects are as follows: the highly interconnected honeycomb structure on the surface of the filling block can provide wide bone ingrowth, the high friction coefficient of the material provides good initial stability for an implant, the low elastic modulus can reduce stress shielding, the tantalum metal material has good strength and ductility, is relatively stable in chemical property and can resist chemical erosion, tantalum also has good biocompatibility, and the manufacturing method is simple and easy to implement.

Description

technical field [0001] The present application relates to the field of medical orthopedic bionic materials, in particular to a bone filling block with a tantalum metal porous structure layer, a manufacturing method and an application. Background technique [0002] Trabecular Knee Filler is an implantable prosthesis used in knee replacement surgery, mainly for bone defect conditions in knee replacement surgery, to provide surgeons with an alternative structural graft Sexual prosthesis, suitable for reconstruction of knee joint bone defects caused by severe degeneration, trauma or other pathological changes. [0003] At present, most of the filling blocks in related technologies are 3D printed titanium alloy trabecular structures. [0004] In view of the related technical solutions mentioned above, the inventor believes that there are the following defects: 3D printing technology uses high-power laser beams to work, the power consumption is relatively large, and the manufactu...
