Metal bone trabecula and bone implant comprising metal bone trabecula

Abstract

The invention discloses a metal bone trabecula. The metal bone trabecula comprises at least three crossed metal bone trabecula supports, a micro-topological grid structure is embedded into the metal bone trabecula, and at least three intersection points are formed between the micro-topological grid structure and the metal bone trabecula supports. The bone trabecula is formed by regularly or irregularly arranging hollowed-out unit structure bodies in a three-dimensional space, the weight reducing effect is obvious, meanwhile, the requirement of rigidity and strength of different areas of partscan be met at the same time, stress shielding is avoided, and good matching of high strength and high weight reduction ratio can be achieved; in addition, after growing into the bone trabecula structure comprising a micro-topological grid, human body sclerotin can be fused with bone, bone ingrow can be induced to the largest extent, and accordingly long-term biological fixation of a prosthesis canbe achieved. Meanwhile, the invention further discloses a bone implant comprising the metal bone trabecula. The bone implant can achieve personalized customization through 3D printing, the process issimplified, and the economic cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of bone trabeculae, in particular to a metal trabecular bone and a bone implant comprising the metal trabecular bone. Background technique [0002] There are bone trabeculae constructed in the orthopedic implant part, which are mainly used to form the internal channel of the implant part, with their excellent porosity and bone ingrowth characteristics, they have been widely used in the field of orthopedic implants in recent years Applications. However, if the structure of the metal trabecular bone is only uniformly distributed and lacks the bionic characteristics of the real structure of the human body, the structural strength of certain parts of it is often due to the uneven force characteristics of the human body during the actual service after implantation. Insufficient, but the structural strength of other parts has been designed. If the structure of the metal trabecular bone is not in the best state of...

Problems solved by technology

However, if the structure of the metal trabecular bone is only uniformly distributed and lacks the bionic characteristics of the real structure of the human body, the structural strength of certain parts of it is often due to the uneven force characteristics of the human body during the actual service after implantation. Insufficient, but the structural strength of other parts has been designed. If the structure of the metal trabecular bone is not in the best state of bonding with the bone, it will directly affect the early stability of the prosthesis, which will also affect the growth of the bone. Conducive to long-term stable prosthesis service
