Abstract
Abstract An aiming apparatus for making transverse bores in a patient's bone in register with the holes or bores of an osteosynthesis aid in the bone, especially an interlocking nail, comprises an elongated holder for the accommodation of an aiming member adapted to be brought into the beam path of an X-ray apparatus, a reception head for receiving a drill or wire drill rotatably supported in the holder, and a power drive supported by the holder for rotatably driving the reception head. The reception head is made of a material transparent to X-ray radiation.
