Gap Gauge and Unit Capable of Checking Flexion Gap Prior to Cutting of Posterior Femur

摘要

The present disclosure relates to total knee arthroplasty used for a knee joint including a tibia and a femur of a patient. More particularly, the present disclosure relates to a gap gauge and a gap gauge unit capable of checking a flexion gap before femur posterior cutting. The gap gauge includes a measurement unit configured to be capable of measuring a gap between a femur posterior cutting surface and a tibia proximal cutting surface during artificial knee joint surgery. The measurement unit is coupled to and positioned in a slot in a femur posterior cutting guide placed on the femur posterior cutting surface so as to check a flexion gap before femur posterior cutting. The measurement unit includes a first measurement unit placed between a tibia proximal cutting surface and the cutting guide before the femur posterior cutting so as to measure the flexion gap.
