Embodiment Construction

[0014] The supporter of the present invention is preferably made of metal tantalum. structured as figure 1 As shown, the supporter of the present invention is provided with a downwardly extending cylindrical side wall 3 on the edge of the circular top plate 1 , and the middle part of the cylindrical side wall 3 is made of uniformly distributed longitudinal gratings 2 . The cylindrical side wall 3 may extend downward at a slightly outward angle, or may extend downward at an angle perpendicular to the top plate 1 . The cylindrical side wall 3 is perpendicular to the top plate 1, which is beneficial to the smooth implantation of the support. After implantation, the instrument will open the outer support of the grid to form a figure 2 As shown in the shape, this expanded shape can not only effectively fill the cavity in the bone, but also facilitate the implantation and growth of new bone.

[0015] In the built-in bone support of the present invention, a circular through hole ...

Abstract

The invention discloses a built-in bone support device. In the built-in bone support device, the edge of a circular top disc is provided with a cylindrical side wall which is extended outward; and the middle part of the cylindrical side wall is provided with longitudinal grids which are distributed uniformly. The designed support device can be used for treating large-area osteonecrosis and bone collapses caused by the large-area osteonecrosis, and achieves the effects of easing pain, repairing the inner structure of a femoral head, and recovering the femoral head. The built-in bone support device can only be used for treating femoral head necrosis and can also be used for treating osteonecrosis of other parts.

Description

technical field [0001] The invention relates to the technical field of osteonecrosis treatment, in particular to a built-in bone support. Background technique [0002] In the prior art, implanting a support into the bone cavity is used to treat bone collapse caused by necrosis of the femoral head. Chinese patent CN2699849 discloses a support therapy device for necrosis of the femoral head, which is made of a Ni—Ti alloy stent, and the stent is in the shape of a hollow tennis ball, which is formed by cross braiding of metal wires. The stent made of memory alloy cannot have proper therapeutic effect after being implanted in the human body because its deformability is not enough to restore the structure and shape when it is finalized. Contents of the invention [0003] The purpose of the present invention is to provide a built-in bone support suitable for deformation after being implanted into the human body, so as to effectively treat the collapse problem caused by osteonec...
