Composite titanium body for spinal implant interbodies
The granted patent US12064354B2 describes a composite interbody system designed for spinal applications. The system features a body with distinct anterior and posterior faces, a top portion, and a bottom portion, all separated by a medial portion. The anterior face is constructed from a solid metal alloy, while the top and bottom portions are made from a porous metal. The design includes two locking mechanisms that utilize inwardly extending channels for securing bone screws. Each locking mechanism consists of a cylinder with tabs that project into corresponding bores, allowing for secure anchoring of bone screws. The system is engineered to enable the tabs to be displaced by the pressure of inwardly moving bone anchors, ensuring a stable fixation.
Further specifications detail that the anterior face and medial portion may be formed from a single piece of titanium alloy, with the porous metal comprising diffusion-bonded sheets of porous titanium. The manufacturing process involves carving a solid titanium body to create voids for the top and bottom portions, followed by diffusion bonding of porous titanium to these voids. Additionally, the patent outlines that at least one of the bores may be partially threaded to engage with the corresponding threads of the bone screws, enhancing the interbody system's stability and functionality. This innovative design aims to improve the performance and reliability of spinal fixation devices.
