LOW-MODULUS MEDICAL IMPLANTATION POROUS SUPPORT STRUCTURE

Title:

LOW-MODULUS MEDICAL IMPLANTATION POROUS SUPPORT STRUCTURE

Document Type and Number:

WIPO Patent Application WO/2016/023403

Kind Code:

A1

Abstract:

A low-modulus medical implantation porous support structure used for being implanted into a bone tissue is formed by sequentially overlaying multiple basic units in a three-dimensional space along three-dimensional directions. Each basic unit is formed by a quadruple prism body or a hexagonal prism body with a central communication hole, formed by four or six side walls. Each side wall is formed by an X-shaped framework structure formed by intersecting two square ribs. The central communication holes of adjacently arranged basic units along the axis of the quadruple prism body or the hexagonal prism body are mutually communicated. The structure reduces the implantation modulus, ensures that the implantation body modulus perfectly matches the implantation strength, improves the configuration of a traditional metal implant, optimizes the mechanical distribution and reduces the stress shielding effect; the structure has a regular through hole structures, is beneficial to the ingrowth of bone tissues, and can enhance the mutual locking between the bone tissue and the implant, and can shorten the rehabilitation time of a patient.
