Abstract

The invention relates to a device for exerting axial forces on bone fragments or vertebral bodies. The inventive device comprises A) a first connecting element (1); B) a second longitudinal connecting element (2) which is displaceable relative to the first connecting element (1); C) a longitudinal support (4) with a longitudinal axis (5) and a front end (6) that can be linked with the first connecting element (1); D) a tubular sleeve (8) that is coaxial relative to the longitudinal axis (5) in which the longitudinal support (4) is displaceable parallel to the longitudinal axis (5) and that comprises a front end (9) that is directed against the first connecting element (1); E) at least one first lever (12) that rotatably links the front end (9) and the second connecting element (2); F) at least one second lever (13) that is rotatably disposed on the first connecting element (1) and on the second connecting element (2) so that G) a relative movement between the front end (9) and the first connecting element (1) results in a relative movement between the first and the second connecting element (1; 2) along a line (20) that substantially extends traversely to the longitudinal axis (5).
