Abstract
A device for the patient-specific, individual anatomic placement of bore channels when attaching artificial ligaments to bones, namely for use in placing boreholes on the thigh and lower leg during anterior cruciate ligament reconstruction, is provided with a probe () to be introduced into a joint via an arthroscopy portal and with a targeting head () disposed on the distal end of the probe. The targeting head () comprises a targeting template () which is produced individually using a 3-D imaging method, in particular 3-D magnetic resonance tomography (3-D-MRT) or 3-D computer tomography (3-D-CT), and which is a negative imprint of the osseous surface relief in the region where the torn ligament attaches to the bone in question, in particular where the cruciate ligament attaches to the thigh or lower leg. The targeting template () comprises at least one passage () for marking the bore channel that is to be produced on the bone, and a hand grip () is provided on the proximal end of the probe () for holding and positioning. The invention also relates to a method for producing a corresponding device.
