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, wherein 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, wherein 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, wherein 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, wherein the first measurement unit includes a cutting slot coupling unit coupled to the slot in the cutting guide and a tibia seating portion seated on the tibia proximal cutting surface, and wherein the cutting slot coupling unit includes a blade configured to capable of being coupled to the cutting slot in the cutting guide and inserted into the cutting slot in the cutting guide, and a cutting block reception groove configured to receive a lower portion of the cutting guide during insertion of the blade so as to secure an insertion depth of the gap gauge.
