Abstract

The bone trabecula structure of the utility model is provided with holes in the transverse and vertical directions on the basis of the trabecula with burrs, so that the trabecula structure not only keeps the original advantages on the basis of ensuring the strength of the trabecula, improves the adhesion, increment and differentiation capacity of osteoblasts, is beneficial to bone growth, has large friction force and is beneficial to the initial stability; the interconnection intercommunity is higher, and what make nutrients etc. can be transported is more smooth, has increased the place area of metabolism, makes the bone grow into the progress more rapidly, and the bone growth effect is more firm.

Description

Bone trabecula structure

Technical Field

The utility model relates to a medical appliance, in particular to a bone trabecula structure.

Background

In the prior art, the trabecular bone has single diameter and single aperture, is not favorable for meeting the requirements of bone ingrowth, better soft tissue ingrowth and cell proliferation, can not eliminate the problems of stress shielding phenomenon and the like; the 3D printing cushion block belongs to a micropore structure, the aperture is small, bone grafting cannot be carried out in the operation, and the bone growth effect is relatively poor; the spacer prosthesis is relatively heavy; the elastic modulus is high, and the stress shielding phenomenon is easy to occur after the operation.

Therefore, a bone trabecular structure with high stability and good bone ingrowth effect is urgently needed.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a bone trabecula structure, bone trabecula surface is equipped with unevenness's burr structure, and bone trabecula is provided with more than one allies oneself with the through-hole, through inclined hole interconnect between the intercommunicating pore, allies oneself with the through-hole and also passes through inclined hole UNICOM with the bone trabecula outside.

Furthermore, the shape and arrangement mode of the burr structure can be adjusted.

Further, the number of the communication holes is 1-3.

Furthermore, the inclined holes are unevenly distributed in the radial direction of the trabecular bone and are distributed at different angles of the section of the trabecular bone.

Further, the trabecula is manufactured by 3D printing and made of tantalum or titanium.

Furthermore, the diameter of the trabecula is 1mm-2 mm;

further, the shape and arrangement of the preferred burr structure can be adjusted, thereby increasing the roughness of the overall structure.

Further, the diameter of the communicating hole is preferably 0.2mm to 0.3 mm.

Furthermore, the diameter of the inclined hole is preferably 0.1mm-0.2 mm; the through holes and the inclined holes are used for conveying nutrient components to positions required by bone production through a siphon effect.

The trabecular bone body is manufactured by 3D printing and is made of tantalum or titanium.

The utility model has the advantages of it is following:

1. the porous structure of the 3D printed trabecula is uneven, and is more beneficial to different bones

2. The 3D printing trabecula is different from the traditional trabecula structure. The traditional trabecular bone is divided into uniform and non-uniform (with burrs) trabecular bone, which is beneficial to bone ingrowth and primary stabilization. The bone trabecula structure of the utility model is provided with holes in the transverse and vertical directions on the basis of the trabecula with burrs, so that the trabecula structure not only retains the original advantages on the basis of ensuring the strength of the trabecula, improves the adhesion, increment and differentiation capacity of osteoblasts, is beneficial to bone growth, has large friction force and is beneficial to the initial stability; the interconnection intercommunity is higher, and what make nutrients etc. can be transported is more smooth, has increased the place area of metabolism, makes the bone grow into the progress more rapidly, and the bone growth effect is more firm.
