Patent JP-2003515425-A (JP)
IPC: A61B17/66
Filed: 1999-12-10
Abstract: The invention relates to a device for exerting axial forces on bone fragments or vertebral bodies. The inventive device comprises a first connecting element, a second longitudinal connecting element which is displaceable relative to the first connecting element and a longitudinal support with a longitudinal axis and a front end that can be linked with the first connecting element. A tubular sleeve is coaxial relative to the longitudinal axis in which the longitudinal support is displaceable parallel to the longitudinal axis and comprises a front end that is directed against the first connecting element. At least one first lever rotatably links the front end and the second connecting element and at least one second lever is rotatably disposed on the first connecting element and on the second connecting element so that a relative movement between the front end and the first connecting element results in a relative movement between the first and the second connecting elements along a line that substantially extends traversely to the longitudinal axis.
