Femoral shaft preparation and surgical instrument assembly for implantation of femoral rod, has receiving cavity worked by smoothing rasp including section corresponding to shape and dimension of chosen size of femoral rod

摘要

The assembly has a covered elongated body comprising a proximal part for working in a metaphyseal zone of a femur (27) and a distal part for working in a diaphyseal zone of the femur. A calibrator (1) comprises a section that is realized in a manner to deeply work in a receiving cavity of an implant comprising a femoral rod (T2) with different sizes. The cavity is worked by a smoothing rasp including a section corresponding to shape and dimension of chosen size of the femoral rod, where the rasp is made of plastic material. An independent claim is also included for a method for dimensioning a femoral shaft preparation and surgical instrument assembly.
