Surgical instruments of the preparation of the femur for the placement of a transplant double beam intended to reconstruct a ligament crosses previous

摘要

This instrumentation surgery (1) comprises an ancillary positioning (30) for the production of the femur (f) of a tunnel designed to receive a first of the two beams of a transplant. This ancillary positioning comprises an elongate body (31), the distal part (35) is provided, at its free end, a head (36) for insertion in a tunnel (f) carried out beforehand through the femur and intended to receive the second beam of the transplant. In order to improve the precision and efficiency of the ancillary device for positioning, the insertion head has an external surface (36a) substantially frustoconical divergent towards the remainder of the distal part.
