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
The invention belongs to metal bone trabecula technical field, be specifically related to a kind of metal bone trabecula interface fixed structure.
Background technology
3D prints metal bone trabecula with the porosity of its excellence and Bone Ingrowth characteristic, is widely used in recent years in orthopaedics implant field.But, if the bone trabecular surface of metal lacks the frictional force with synosteosis face, directly can affect the early stage stability of prosthese, and then affect Bone Ingrowth, be unfavorable for that long-term prosthese is fixed.The method that metal current bone trabecula surface increases roughness increases frictional force.But this unavoidably reduces contact surface area, be unfavorable for Bone Ingrowth again, affect prosthese chronobiological and fix.
Summary of the invention
The object of the embodiment of the present invention is the above-mentioned deficiency overcoming prior art, provides a kind of metal bone trabecula interface fixed structure, bone trabecula prosthese can be made firmly to be combined with bone bed.
In order to realize foregoing invention object, the technical scheme of the embodiment of the present invention is as follows:
A kind of metal bone trabecula interface fixed structure, comprising: at least three crossing metal bone trabecula supports, also comprise metal bone trabecula protruding, the point of intersection of at least three crossing metal bone trabecula supports described in one end of described metal bone trabecula projection is arranged on.
Further: the length of described metal bone trabecula projection is 200-2000 micron.
Further: the shape of described metal bone trabecula projection is cylindrical.
Further: the diameter of described metal bone trabecula projection is 30-120 micron.
Further: the diameter of described metal bone trabecula projection is identical with the diameter of described metal bone trabecula support.
Further: the angle between described metal bone trabecula projection and described metal bone trabecula support that each intersects is equal.
Further: the angle between the adjacent described metal bone trabecula support intersected is equal.
The present invention has following beneficial effect:
1, the metal bone trabecula interface fixed structure of the embodiment of the present invention is protruding by arranging metal bone trabecula, this metal bone trabecula projection can be deep in bone and form pile-driving effect, bone trabecula prosthese is firmly combined with bone bed.
2, the metal bone trabecula interface fixed structure of the embodiment of the present invention does not affect the contact area in metal bone trabecula surface and synosteosis face, the bone trabecular porosity of metal is not affected yet, Bone Ingrowth can be induced to the full extent, thus reach the long-term biological fixation of prosthese.
Accompanying drawing explanation
Fig. 1 is the structural representation of the metal bone trabecula interface fixed structure of the embodiment of the present invention.
In figure 1, metal bone trabecula support; 2, metal bone trabecula is protruding.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiments of the invention disclose a kind of metal bone trabecula interface fixed structure.As shown in Figure 1, be the structural representation of the metal bone trabecula interface fixed structure of the embodiment of the present invention.This metal bone trabecula interface fixed structure comprises: at least three crossing metal bone trabecula supports 1 and metal bone trabecula projection 2.One end of this metal bone trabecula projection 2 is arranged on the point of intersection of at least three crossing metal bone trabecula supports 1.
The metal bone trabecula interface fixed structure of the embodiment of the present invention is by arranging metal bone trabecula projection 2, this metal bone trabecula projection 2 can be deep in bone and form pile-driving effect, bone trabecula prosthese is firmly combined with bone bed, and this metal bone trabecula interface fixed structure does not affect the contact area in metal bone trabecula surface and synosteosis face, the bone trabecular porosity of metal is not affected yet, Bone Ingrowth can be induced to the full extent, thus reach the long-term biological fixation of prosthese.
Preferably, the length of this metal bone trabecula projection 2 is about slightly less than bone trabecula diameter.Therefore, the length of this metal bone trabecula projection 2 is 200-2000 micron.
Preferably, the shape of metal bone trabecula projection 2 is cylindrical, improves its bio-imitability.
In a preferred embodiment, when metal bone trabecula protruding 2 is cylindrical, the diameter of this metal bone trabecula projection 2 is 30-120 micron.In an additional preferred embodiment, the diameter of metal bone trabecula projection 2 is identical with the diameter of metal bone trabecula support 1.The selection of the diameter of above-mentioned metal bone trabecula projection 2 makes it not affect the contact area in metal bone trabecula surface and synosteosis face as much as possible, the bone trabecular porosity of metal is not affected yet, Bone Ingrowth can be induced to the full extent, thus reach the long-term biological fixation of prosthese.
Preferably, the angle between metal bone trabecula protruding 2 and each metal bone trabecula support 1 intersected is equal.The angle of the adjacent metal bone trabecula support 1 intersected is equal.Above-mentioned design makes this metal bone trabecula interface fixed structure more firm.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
