Description
Technical field
The collapsible tool system field that the present invention relates to the fixing Anatomical Reconstruction shin bone stop footmark of orthopaedics district, is specifically related to a kind of orthopaedics posterior cruciate ligament of knee joint Anatomical Reconstruction system.
Background technology
Posterior cruciate ligament of knee, be called for short PCL, refer to front part of condyle lateral surface in human body knee joint femur, the fine and close collagenous tissue sending after articular cartilage, from fossa intercondyloidea, upper, interior oblique tibial plateau rear, under, outside, terminate in ridge trailing edge between tibial plateau condyle and the ligament structure that forms. Have vasa vasorum and neural distribution at its strand, shin stop two ends, major function is avoid shin bone rear heavy, with kneed rear in and together with rear outer complex, maintain kneed backward and rotational stabilization.
But, once PCL damage is repaired pretty troublesome. Clinical statistics both domestic and external shows, the reconstruction operations amount of PCL fracture is far fewer than anterior cruciate ligament of knee joint, and to rebuild relevant surgical experience obviously on the low side especially to PCL; Add PCL shin bone stop district and be positioned at area intercondylaris posterior, popliteal nest blood vessel and Neural Area that next-door neighbour's danger is dangerous. Therefore, this operation only has safe and effective development of small part large hospital ability at present at home, for being engaged in most of basic hospitals of trauma care, the dislocation of knee joint that relates to PCL fracture usually needs clinical operation treatment, but aforesaid two reasons have hindered the popularization of PCL reconstruction operations in basic hospital. So find the PCL operation method of " safe, effective, easy ", and design accordingly corresponding operation tool, just become and promote PCL reconstruction, reduce operation risk and reduce the of paramount importance link of learning difficulty.
