Abstract
The invention relates to a drilling jig for the determination of the axis of a femur head prosthesis. A guide tube ( ), around whose longitudinal axis ( ) a sensing probe can be rotated, has a rounded head ( ) which is supported in a housing ( ) pivotable in all directions and fixable by first clamping elements ( ), in order to fix its longitudinal axis in a desired angle. The housing ( ) is displaceable in all directions transversely to its longitudinal axis with respect to a base part ( ) which can be anchored to the femur head ( ) and fixable by two clamping elements ( ) in order to define the position of the longitudinal axis ( ) of the guide tube ( ) by rotation of a sensing probe around this longitudinal axis ( ) relative to the cross-section of the femur neck ( ).
