Osteosynthesis Screw with Angular Indexing and Universal Screwdriver Compatibility
Summary
USPTO granted patent US12605194B2 to NOVASTEP on April 21, 2026, covering an osteosynthesis clamping screw with a multi-lobe socket design. The invention features at least three regular socket shapes with vertices inscribed in a circumscribed circle, with adjacent vertices connected to form convex indexing lobes whose radius of curvature equals the circumscribed circle radius, enabling universal compatibility with complementing screwdriver shapes. The patent contains 9 claims and was filed on January 31, 2022 under application number 18275078.
What changed
USPTO issued patent US12605194B2 to NOVASTEP on April 21, 2026, covering a new osteosynthesis clamping screw design with a socket comprising at least three regular shapes and convex indexing lobes. The socket geometry allows evenly angular distribution to accept complementing screwdriver shapes, creating universal compatibility across driver types.
Medical device manufacturers and orthopedic implant companies should note this intellectual property grant for potential licensing discussions or design-around considerations in the osteosynthesis screw space. The patent's indexing lobe geometry may represent a design alternative for surgical fixation devices requiring angular positioning control.

Abstract
The present invention relates to a clamping screw (6) for osteosynthesis, comprising at least one screw thread (7, 10) along a main axis (X) and, at its end referred to as the apex end (11), having a socket (12) which, about said main axis (A), has evenly angularly distributed shapes designed to accept complementing shapes of a screwdriver (19) engaged in said socket (12), notable in that the socket (12) of the screw (6) comprises at least three regular shapes (13) of which the vertices are inscribed inside a circle referred to as circumscribed circle (30) and at least two adjacent vertices of the socket (21) are connected to form a convex lobe referred to as indexing lobe (16) of which the radius of curvature is equal to the radius of the circumscribed circle (30).
