PROBLEM TO BE SOLVED: To provide a sizing caliper for determining an optimum size of a femoral component of a knee prosthesis.SOLUTION: A sizing caliper 1 includes a caliper body 2, a drill guide body 6b, a stylus tower 4, and a stylus 3 with scale slidably linked to the stylus tower. The caliper body, drill guide body, and stylus tower are slidably joined to each other by a link pin 5 extending laterally through these. When the caliper body and stylus tower are moved linearly in the opposite direction with respect to the grill guide body, the caliper body and stylus tower are moved linearly at an equal ratio to the drill guide body. |
