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

Abstract

The invention discloses a metal trabecular bone, which comprises at least three intersecting metal trabecular supports, and a micro-topological grid structure is embedded in the metal trabecular bone, and the micro-topological grid structure is connected with the metal bone trabecular The trabecular support has at least three intersections, and part of the outer surface of the metal trabecular is provided with a bone trabecular coating. The trabecular bone of the present invention is formed by regular or irregular arrays of hollowed-out unit structures in three-dimensional space, which not only has an obvious weight-reducing effect, but also satisfies the stiffness and strength of different parts of the parts at the same time, avoiding stress shielding, Achieve a good match of high strength and high weight loss ratio; in addition, human bone grows into the trabecular bone structure and can be integrated with the bone, so that the trabecular bone prosthesis can be firmly combined with the bone bed, and can Induce bone ingrowth to the greatest extent so as to achieve long-term biological fixation of the prosthesis. At the same time, the invention also discloses a bone implant comprising the metal bone trabecular.

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...
