Intersomatic Implant and Tool for Installing Such an Implant

摘要

The present invention concerns an intersomatic implant (2) comprising a body (4) suitable for being inserted between two vertebrae (1) to space them a predetermined distance apart, the body (4) being provided on either side, respectively, with a contact surface (5, 5′) with die corresponding vertebrae (1). The body (4) is formed from an oblong part of predetermined thickness provided at a first so-called proximal end with a gripping cam (9) mounted movable in rotation relative to the part about an axis perpendicular to the two surfaces (5, 5), between two predetermined angular positions. The contact surfaces (5, 5′) are either parallel or substantially parallel to one another, and each contact surface (5, 5′) of the body (4) with a corresponding vertebra (1) comprises a set of curved longitudinal protrusions (7, 7′, 7″) which decrease in height towards the distal ends thereof.

主权项

1. An intersomatic implant (2) comprising a body (4) that can be inserted between two vertebrae (1) to part them by a determined distance and fit a bone graft, the body (4) being equipped on each side and respectively with a contact face (5, 5′) for contact with the corresponding vertebra (1), the body (4) being formed of an oblong component of said determined thickness equipped at a first end, called the proximal end, with a gripping cam (9) mounted with the ability to rotate with respect to the component about an axis perpendicular to the two faces (5, 5′), between two determined angular positions,
characterized in that the contact faces (5, 5′) are parallel or substantially parallel, and in that each contact face (5, 5′) of the body (4) for contact with a corresponding vertebra (1) comprises a set of curved longitudinal reliefs (7, 7′, 7″) substantially parallel to the lateral walls (6, 6′) of a height that decreases toward their distal ends, and the reliefs consist of ribs or of grooves and/or of an alternation of at least one rib and of at least one groove.
