Abstract:
A drilling jig for the determination of the axis of a femur head prosthesis (27) having a guide tube (6) around whose longitudinal axis (14) a sensing probe (13) can rotate in a plane of rotation (15) to sense a neck (16) of the femur at the transition to its femur head (10) and to centre the position of the longitudinal axis (14) with respect to the neck (16) of the femur by a displacement of the guide tube (6), wherein the guide tube (6) is pivotally mounted with a rounded head (7) in a housing (3) and can be fixed with first clamping elements (5) at a designated pivot angle &agr; of its longitudinal axis (14) relative to the longitudinal axis (17) of the housing (3); and the housing can be displaced in any direction transversely to its longitudinal axis (17) with respect to a base part (1) with a cut-out (37) which is provided for the fastening to a femur head (10) and can be fixed in a designated displacement position by second clamping elements.
