Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] The embodiment of the invention discloses a metal bone trabecular interface fixing structure. Such as figure 1 As shown, it is a structural schematic diagram of the interface fixation structure for metal trabecular bone according to the embodiment of the present invention. The interface fixing structure for metal trabecular bone includes: at least three intersecting metal trabecular bone brackets 1 and metal trabecular bone protrusions 2 . One end of the metal trabecular bone protrusion 2 is arranged at the intersection of at least three intersecting metal trabecular bone brackets 1 .

Abstract

The invention discloses an interface fixing structure for metal bone trabeculae. The interface fixing structure for the metal bone trabeculae comprises at least three intersected metal bone trabecula supports (1) and a metal bone trabecula projection (2), and one end of the metal bone trabecula projection (2) is arranged at the intersection of the at least three intersected metal bone trabecula supports (1). By the aid of the metal bone trabecula projection which can penetrate into a bone to form a pile driving effect, a bone trabecula prosthesis can be steadily combined with a bone bed, a contact area of a bone trabecula surface and a synostosis surface is unaffected, porosity of the metal bone trabecula is unaffected as well, and bone ingrowth can be induced to the maximum extent so as to realize long-term biological fixation of the prosthesis.

Description

technical field [0001] The invention belongs to the technical field of metal trabecular bone, and in particular relates to an interface fixing structure for metal trabecular bone. Background technique [0002] 3D printed metal trabecular bone has been widely used in the field of orthopedic implants in recent years due to its excellent porosity and bone ingrowth characteristics. However, if the surface of the metal trabecular bone lacks friction with the osseointegration surface, it will directly affect the early stability of the prosthesis, and then affect the bone ingrowth, which is not conducive to long-term prosthesis fixation. At present, the method of increasing the roughness of the surface of metal trabecular bone is used to increase the friction force. However, this inevitably reduces the surface contact area, which is not conducive to bone ingrowth, and affects the long-term biological fixation of the prosthesis. Contents of the invention [0003] The purpose of ...
