Preparation method and use of medical metal artificial bone trabecula

Abstract

The invention discloses preparation and application of metal artificial bone trabecula for medical purposes. The structural design of the metal artificial bone trabecula is completed by a computer, and then inputted in an electron beam fusion former; the high temperature generated by electron beams is used to carry out the stratified scanning and high-temperature fusion to titanium alloy powder in the former so as to obtain the metal artificial bone trabecula with bio-cancellous bone morphology, strength and elasticity modulus and a rough and loose outer surface formed by a porous structure. The obtained artificial bone trabecula has mechanical and biological characteristics similar to a human bone, high surface friction coefficient, stable structure and wide range of application, and is applicable to various bone defects, bone filling, bone supporting, bone remodeling and bone repair in a human skeletal system as well as bone restoration of bone remodeling and bone repair of different bone joints of a human body.

Description

Technical field

[0001] The invention relates to the technical field of orthopedic medical materials, in particular to a medical metal artificial bone trabecular. Background technique

[0002] As we all know, in clinical orthopedic surgery, bone repair, bone filling and bone support are commonly used treatment methods. Bone defects caused by bone tumors, intervertebral disc lesions, osteoarthritis and trauma are very common in clinical practice. Parts involve various parts of the human skeletal system, including the skull, trunk bones, limb bones and joints. In various operations that require bone grafting, some require filling of bone defects to restore bone continuity and bone volume, some require structural bone grafting to support stability or fusion, and some Reconstruction or reshaping is required to achieve the purpose of restoration. The source of bone graft is divided into autologous bone or allogeneic bone. Due to its strong regeneration ability, fast healing, an...
