発明の名称 (英語) SPINAL FUSION IMPLANT NEW
発明の概要(英語) The purpose of the present invention is to provide a spinal fusion implant capable of preserving turning properties of vertebral bodies, and in addition, capable of preventing false screwing (false insertion) of screws. Connection plates 3 constituting a spinal fusion implant 101 each have, on a ventral-side surface 3b, a convex-shaped portion 8 that is fitted into a concave-shaped portion of an intervertebral joint 53. In addition, a center hole 3d through which a center rod 4 is slidably inserted is formed on a side surface of the connection plate 3, such that the center of the hole is positioned closer to the back side than a virtual line L1 connecting midpoints on arc-shaped contour lines C of the concave-shaped portions of the adjacent intervertebral joints 53 when viewed from the head side of a human body.
従来技術、競合技術の概要(英語) BACKGROUND ART
As this kind of technology, for example, be those described in Patent Document 1. Spinal fixation system of the Patent Document 1, the fixing member is fixed to the vertebral body are referred to as the screw, the screw rod and a coupled to each other. Patent Document 1 for example as disclosed in Fig. 5, regarding the 1 vertebra of the present screw 2, screwed to the vertebral body are fixed (puncturing). Then, a total of 2 sets are arranged in parallel, a plurality of screw and rod, the relative position of adjacent vertebral bodies are fixed. In addition, each of the vertebral body in order to more firmly fixed, and the horizontal adjacent rods may be connected to the connector disclosed in the literature.
In addition, in Patent Document 1 is not particularly described, in the above-mentioned screw, rod, and the horizontal connector, formed of a metal material such as titanium.
