Gap Gauge to check the Flexion Gap before Posterior Cutting

摘要

The present invention relates to a knee joint replacement (Total Knee Anrthroplasty) used for the knee joint including the tibia and femur to be treated, and more particularly, to measure the distance between the posterior femur section and the proximal tibia section during artificial knee surgery. It includes a measuring part that can be measured, and the measuring part is coupled to the slot of the posterior femur cutting guide located on the distal cut surface of the femur and is positioned to check the bending interval before cutting the posterior femur, and the measuring part is before cutting the posterior femur, proximal tibia A first measuring unit positioned in a space between the cutting surface and the cutting guide to measure a bending interval, the first measuring unit includes a cutting slot coupling unit coupled to the slot of the cutting guide, and a tibia seated on the proximal tibia cutting surface Including a seating portion, the cutting slot coupling portion is configured to be coupled to the cutting slot of the cutting guide, a blade inserted into the cutting slot of the cutting guide, and a gap gauge by receiving a lower portion of the cutting guide when the blade is inserted It relates to a gap gauge and a unit capable of confirming the bend gap before cutting the posterior femur including a cutting block receiving groove to secure the insertion depth of the femur.
